EXHIBIT 10.12

                              EMPLOYMENT AGREEMENT

      This Employment Agreement (this "Agreement") is entered into this 30th day
of August, 1999 (the "Effective Date") by and between DAVID P. TUSA ("Employee")
and BILLING CONCEPTS CORP., a Delaware corporation (the "Company").

                                   WITNESSETH:

      WHEREAS, the Company and Employee desire to enter into an agreement to
establish the terms of Employee's employment with the Company and to set forth
each party's duties and obligations to the other;

      NOW, THEREFORE, in consideration of the foregoing premises, the mutual
agreements contained herein and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, this Agreement is
entered into to read as follows:

                                    ARTICLE I
                                     DUTIES

      1.1 DUTIES. During the term of this Agreement, the Company agrees to
employ Employee as Senior Vice President and Chief Financial Officer of the
Company, and Employee agrees to serve the Company in such capacities or in such
other capacities (subject to Employee's termination rights under Section 4.2) as
the Board of Directors of the Company may direct, all upon the terms and subject
to the conditions set forth in this Agreement.

      1.2 EXTENT OF DUTIES. Employee shall devote all of his business time,
energy and skill to the affairs of the Company as the Company, acting through
its Board of Directors, shall reasonably deem necessary to discharge Employee's
duties in such capacities. Employee may participate in social, civic,
charitable, religious, business, education or professional associations, so long
as such participation would not materially detract from Employee's ability to
perform his duties under this Agreement. Employee shall not engage in any other
business activity during the term of this Agreement without the prior written
consent of the Company, other than the passive management of employee's personal
investments or activities which would not materially detract from Employee's
ability to perform his duties under this Agreement. Notwithstanding the above,
Employee may spend one (1) business day per week through September 30, 1999 at
the offices of his former employer in Houston, Texas.

                                   ARTICLE II
                               TERM OF EMPLOYMENT

      2.1 GENERAL TERM OF EMPLOYMENT. The term of this Agreement shall commence
on the Effective Date and continue for a period of one (1) year. The term of
this Agreement shall be

                                       1
<PAGE>
automatically extended on each one (1)-year anniversary of this Agreement for an
additional one-year term unless, at least thirty (30) days prior to the end of
the then effective one-year term, the Company shall give Employee written notice
of its election to terminate this Agreement as of the end of the then effective
one-year term. In the event the Company elects to so terminate this Agreement,
the Company shall pay Employee, within fifteen (15) days of the effective date
of such termination, a lump-sum payment equal to (without discounting to present
value) one times his then effective annual base salary under Section 3.1 hereof.
Payment of such sum by the Company shall constitute Employee's full severance
pay, and the Company shall have no further obligation to Employee arising out of
such termination. This Agreement is also subject to earlier termination as
hereinafter provided.

                                   ARTICLE III
                                  COMPENSATION

      3.1 ANNUAL BASE COMPENSATION. As compensation for services rendered under
this Agreement, Employee shall be entitled to receive from Company an annual
base salary of $175,000 (before standard deductions) during the initial term of
this Agreement. Employee's annual base salary shall be subject to review and
adjustment by the Compensation Committee of the Company (the "Compensation
Committee") on an annual basis, provided that any such adjustment shall not
result in a reduction in Employee's annual base salary below $175,000 without
Employee's consent. Employee's annual base salary shall be payable at regular
intervals in accordance with the prevailing practice and policy of the Company.

      3.2 APARTMENT AND UTILITIES. The Company will provide Employee with a
Company-paid furnished corporate apartment in San Antonio, Texas, through
February 29, 2000, or such later date if deemed appropriate in light of duties
necessary in his capacity as Senior Vice President and Chief Financial Officer.

      3.3 INCENTIVE BONUS. As additional compensation for services rendered
under this Agreement, the Compensation Committee may, in its sole discretion and
without any obligation to do so, declare that Employee shall be entitled to an
annual incentive bonus (whether payable in cash, stock, stock rights or other
property) as the Compensation Committee shall determine. If any such bonus is
declared, the bonus shall be payable in accordance with the terms prescribed by
the Compensation Committee.

      3.4 RELOCATION EXPENSES. The Company will reimburse Employee for expenses
incurred in moving his household from Houston, Texas to San Antonio, Texas, up
to an aggregate of $52,500, pursuant to the terms of the Employee Relocation
Agreement effective August 30, 1999 by and between the Company and Employee, a
copy of which is attached hereto as Exhibit "A." The Company understands that
Employee may choose to lease a residence in San Antonio and purchase a home at a
later date; therefore, relocation expenses are deemed to include those expenses
related to the later home purchase and associated move.

                                       2
<PAGE>
      3.5 OTHER BENEFITS. Employee shall, in addition to the compensation
provided for in Sections 3.1, 3.2, 3.3 and 3.4 above, be entitled to all
benefits available to Company executives, including the following:

            (a) MEDICAL, HEALTH AND DISABILITY BENEFITS. Employee shall be
entitled to receive all of the medical, health and disability benefits that may,
from time to time, be provided by the Company to its executive officers.

            (b) OTHER BENEFITS. Employee shall also be entitled to receive any
other benefits provided by the Company to all employees of the Company as a
group, or all executive officers of the Company as a group, including any profit
sharing, 401(k), deferred compensation or retirement benefits.

            (c) VACATION PAY. Employee shall be entitled to an annual vacation
as determined in accordance with the prevailing practice and policy of the
Company.

            (d) HOLIDAYS. Employee shall be entitled to holidays in accordance
with the prevailing practice and policy of the Company.

            (e) REIMBURSEMENT OF EXPENSES. The Company shall reimburse Employee
for all expenses reasonably incurred by Employee on behalf of the Company in
accordance with the prevailing practice and policy of the Company, including
those necessary to maintain his professional license.

                                   ARTICLE IV
                                   TERMINATION

      4.1 TERMINATION BY THE COMPANY WITHOUT CAUSE. Subject to the provisions of
this Section 4.1, this Agreement may be terminated by the Company without cause
upon thirty (30) days' prior written notice thereof given to Employee. In the
event of termination pursuant to this Section 4.1, the Company shall pay
Employee, within fifteen (15) days of the effective date of such termination, a
lump-sum payment equal to (without discounting to present value) (a) one half
(1/2) of his then effective annual base salary under Section 3.1 hereof if such
termination occurs during the first twelve (12) months of the term of this
Agreement or (b) one times his then effective annual base salary under Section
3.1 hereof if such termination occurs after the first twelve (12) months of the
term of this Agreement. Payment of such sum by the Company shall constitute
Employee's full severance pay, and the Company shall have no further obligation
to Employee arising out of such termination.

      4.2 VOLUNTARY TERMINATION BY EMPLOYEE FOR GOOD REASON. Employee may at any
time voluntarily terminate his employment for "good reason" (as defined below).
In the event of such voluntary termination for "good reason," the Company shall
pay Employee, within fifteen (15) days of the effective date of such
termination, a lump-sum payment equal to (without discounting to present value)
(a) one half (1/2) of his then effective annual base salary under Section 3.1
hereof if such termination occurs during the first twelve (12) months of the
term of this Agreement or (b)

                                       3
<PAGE>
one times his then effective annual base salary under Section 3.1 hereof if such
termination occurs after the first twelve (12) months of the term of this
Agreement.

            For purposes of this Agreement, "good reason" shall mean the
occurrence of any of the following events:

            (a) Removal from the offices Employee holds on the date of this
Agreement or a material reduction in Employee's authority or responsibility,
including, without limitation, involuntary removal from the Board of Directors,
but not including termination of Employee for "cause," as defined below;

            (b) A reduction in the Employee's then effective base salary under
Section 3.1; or

            (c) A requirement that Employee relocate more than thirty-five (35)
miles from the Company's current corporate headquarters; or

            (d) The Company otherwise commits a material breach of this
Agreement.

      4.3. TERMINATION BY THE COMPANY FOR CAUSE. The Company may terminate this
Agreement at any time if such termination is for "cause" (as defined below), by
delivering to Employee written notice describing the cause of termination thirty
(30) days before the effective date of such termination and by granting Employee
at least thirty (30) days to cure the cause. In the event the employment of
Employee is terminated for "cause," Employee shall be entitled only to the base
salary earned PRO RATA to the date of such termination with no entitlement to
any base salary continuation payments or benefits continuation (except as
specifically provided by the terms of an employee benefit plan of the Company).
Except as otherwise provided in this Agreement, the determination of whether
Employee shall be terminated for "cause" shall be made by the Board of Directors
of the Company, in the reasonable exercise of its business judgment, and shall
be limited to the occurrence of the following events:

            (a) Conviction of or a plea of NOLO CONTENDERE to the charge of a
felony (which, through lapse of time or otherwise, is not subject to appeal);

            (b) Willful refusal without proper legal cause to perform, or gross
negligence in performing, Employee's duties and responsibilities;

            (c) Material breach of fiduciary duty to the Company through the
misappropriation of Company funds or property; or

            (d) The unauthorized absence of Employee from work (other than for
sick leave or disability) for a period of thirty (30) working days or more
during any period of forty-five (45) working days during the term of this
Agreement.

                                       4
<PAGE>
      4.4 TERMINATION UPON DEATH OR PERMANENT DISABILITY. In the event that
Employee dies, this Agreement shall terminate upon Employee's death. Likewise,
if Employee becomes unable to perform the essential functions of the position,
with or without reasonable accommodation, on account of illness, disability or
other reason whatsoever for a period of more than six (6) consecutive or
nonconsecutive months in any twelve (12)-month period, this Agreement shall
terminate effective upon such incapacity, and Employee (or his legal
representatives) shall be entitled only to the base salary earned PRO RATA to
the date of such termination with no entitlement to any base salary continuation
payments or benefits continuation (except as specifically provided by the terms
of an employee benefit plan of the Company).

      4.5 VOLUNTARY TERMINATION BY EMPLOYEE. Employee may terminate this
Agreement at any time upon delivering thirty (30) days' written notice of
resignation to the Company. In the event of such voluntary termination other
than for "good reason" (as defined above), Employee shall be entitled to his
base salary earned PRO RATA to the date of his resignation, but no base salary
continuation payments or benefits continuation (except as specifically provided
by the terms of an employee benefit plan of the Company). On or after the date
the Company receives notice of Employee's resignation, the Company may, at its
option, pay Employee his base salary through the effective date of his
resignation and terminate his employment immediately.

      4.6   TERMINATION FOLLOWING CHANGE OF CONTROL.

            (a) Notwithstanding anything to the contrary contained herein,
should Employee at any time within 12 months of the occurrence of a "change of
control" (as defined below) cease to be an employee of the Company (or its
successor), by reason of (i) termination by the Company (or its successor) other
than for "cause" (following a change of control, "cause" shall be limited to the
conviction of or a plea of NOLO CONTENDERE to the charge of a felony which,
through lapse of time or otherwise, is not subject to appeal, or a material
breach of fiduciary duty to the Company through the misappropriation of Company
funds or property) or (ii) voluntary termination by Employee for "good reason
upon change of control" (as defined below), then in any such event, (1) the
Company shall pay Employee, within 45 days of the severance of employment
described in this Section 4.6, a lump-sum payment equal to (without discounting
to present value) one half (1/2) of his then effective annual base salary under
Section 3.1 hereof if such termination occurs during the first twelve (12)
months of the term of this Agreement or one times his then effective annual base
salary under Section 3.1 hereof if such termination occurs after the first
twelve (12) months of the term of this Agreement, (2) Employee shall be entitled
to all benefits provided under Section 3.5 hereof for one year from such
termination, to the extent continuation of such benefits is not prohibited by
applicable state and/or federal law, and (3) immediately prior to the effective
date of such termination, all outstanding stock options held by Employee not
already vested and exercisable shall become fully vested and exercisable.

            (b) As used in this Section, voluntary termination by Employee for
"good reason upon change of control" shall mean (i) removal of Employee from the
offices Employee holds on the date of this Agreement, (ii) a material reduction
in Employee's authority or responsibility, including, without limitation,
involuntary removal from the Board of Directors, (iii) relocation of the
Company's headquarters from Bexar County, Texas, (iv) a reduction in Employee's
then

                                       5
<PAGE>
effective base salary under Section 3.1 or (v) the Company otherwise commits a
breach of this Agreement.

            (c) As used in this Agreement, a "change of control" shall be deemed
to have occurred if (i) any "Person" (as such term is used in Sections 13(d) and
14(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
is or becomes a "beneficial owner" (as defined in Rule 13d-3 under the Exchange
Act), directly or indirectly, of securities of the Company representing more
than 30% of the combined voting power of the Company's then outstanding
securities, or (ii) at any time during the 24-month period after a tender offer,
merger, consolidation, sale of assets or contested election, or any combination
of such transactions, at least a majority of the Company's Board of Directors
shall cease to consist of "continuing directors" (meaning directors of the
Company who either were directors prior to such transaction or who subsequently
became directors and whose election, or nomination for election by the Company's
stockholders, was approved by a vote of at least two thirds of the directors
then still in office who were directors prior to such transaction), or (iii) the
stockholders of the Company approve a merger or consolidation of the Company
with any other corporation, other than a merger or consolidation that would
result in the voting securities of the Company outstanding immediately prior
thereto continuing to represent (either by remaining outstanding or by being
converted into voting securities of the surviving entity) at least 60% of the
total voting power represented by the voting securities of the Company or such
surviving entity outstanding immediately after such merger or consolidation, or
(iv) the stockholders of the Company approve a plan of complete liquidation of
the Company or an agreement of sale or disposition by the Company of all or
substantially all of the Company's assets.

      4.7 EXCLUSIVITY OF TERMINATION PROVISIONS. The termination provisions of
this Agreement regarding the parties' respective obligations in the event
Employee's employment is terminated are intended to be exclusive and in lieu of
any other rights or remedies to which Employee or the Company may otherwise be
entitled at law, in equity or otherwise. It is also agreed that, although the
personnel policies and fringe benefit programs of the Company may be
unilaterally modified from time to time, the termination provisions of this
Agreement are not subject to modification, whether orally, impliedly or in
writing, unless any such modification is mutually agreed upon and signed by the
parties.

                                    ARTICLE V
                   CONFIDENTIAL INFORMATION AND NONCOMPETITION

      5.1 NONDISCLOSURE. During the term of this Agreement and thereafter,
Employee shall not, without the prior written consent of the Board of Directors,
disclose or use for any purpose (except in the course of his employment under
this Agreement and in furtherance of the business of the Company) confidential
information, proprietary data or trade secrets of the Company (or any of its
subsidiaries), including but not limited to customer, business planning or
business strategy information, except as required by applicable law or legal
process; provided, however, that confidential information shall not include any
information known generally to the public or ascertainable from public or
published information (other than as a result of unauthorized disclosure by
Employee) or any information of a type not otherwise considered confidential by
persons engaged in the same business or a business similar to that conducted by
the Company (or any of its

                                       6
<PAGE>
subsidiaries). All documents which Employee prepared or which may have been
provided or made available to Employee in the course of work for the Company
shall be deemed the exclusive property of the Company and shall remain in the
Company's possession. Upon the termination of Employee's employment with the
Company, regardless of the reason for such termination, Employee shall promptly
deliver to the Company all materials of a confidential nature relating to the
business of the Company (or any of its subsidiaries) which are within Employee's
possession or control.

      5.2 NONCOMPETITION. The Company and Employee agree that the services
rendered by Employee hereunder are unique and irreplaceable. For this reason and
in consideration of the benefits of this Agreement, specifically including but
not limited to applicable termination pay provisions, as well as
confidential/proprietary/trade secret information provided to Employee, Employee
hereby agrees that, during the term of this Agreement, he shall not (except in
the course of his employment under this Agreement and in furtherance of the
business of the Company (or any of its subsidiaries)) (i) engage in, as
principal, consultant or employee, any segment of a business of a company,
partnership or firm ("Business Segment") that is directly competitive with any
significant business of the Company in one of its major commercial or geographic
markets or (ii) hold an interest (except as a holder of less than 5% interest in
a publicly traded firm or mutual funds, or as a minority stockholder or
unitholder in a form not publicly traded) in a company, partnership or firm with
a Business Segment that is directly competitive, without the prior written
consent of the Company.

      5.3 VALIDITY OF NONCOMPETITION. The foregoing provisions of Section 5.2
shall not be held invalid because of the scope of the territory covered, the
actions restricted thereby or the period of time such covenant is operative. Any
judgment of a court of competent jurisdiction may define the maximum territory,
the actions subject to and restricted by Section 5.2 and the period of time
during which such agreement is enforceable.

      5.4 NONCOMPETITION COVENANTS INDEPENDENT. The covenants of Employee
contained in Section 5.2 will be construed as independent of any other provision
in this Agreement, and the existence of any claim or cause of action by the
Employee against the Company will not constitute a defense to the enforcement by
the Company of said covenants. Employee understands that the covenants contained
in Section 5.2 are essential elements of the transaction contemplated by this
Agreement, and but for the agreement of Employee to Section 5.2, the Company
would not have agreed to enter into such transaction. Employee has been advised
to consult with counsel in order to be informed in all respects concerning the
reasonableness and propriety of Section 5.2 and its provisions with specific
regard to the nature of the business conducted by the Company, and Employee
acknowledges that Section 5.2 and its provisions are reasonable in all respects.

      5.5 COOPERATION. In the event of termination, and regardless of the reason
for such termination, Employee agrees to cooperate with the Company and its
representatives by responding to questions, attending meetings, depositions,
administrative proceedings and court hearings, executing documents and
cooperating with the Company and its legal counsel with respect to issues,
claims, litigation or administrative proceedings of which Employee has personal
or corporate knowledge. Employee further agrees to maintain in strict confidence
any information or knowledge Employee has regarding current or future claims,
litigation or administrative proceedings involving

                                       7
<PAGE>
the Company (or any of its subsidiaries). Employee agrees that any communication
with a party adverse to the Company, or with a representative, agent or counsel
for such adverse party, relating to any claim, litigation or administrative
proceeding, shall be solely and exclusively through counsel for the Company.

      5.6 REMEDIES. In the event of a breach or threatened breach by the
Employee of any of the provisions of Sections 5.1, 5.2 or 5.5, the Company shall
be entitled to a temporary restraining order and an injunctive restraining the
Employee from the commission of such breach. Nothing herein shall be construed
as prohibiting the Company from pursuing any other remedies available to it for
such breach or threatened breach, including the recovery of money damages.

                                   ARTICLE VI
                                 INDEMNIFICATION

      The Company shall indemnify and hold harmless Employee from any and all
claims (whether in court or before a regulatory or administrative body),
liabilities, damages and expenses, including without limitation reasonable
attorneys' fees incurred by Employee or his agents, arising out of or related to
the acts or omissions (including negligence) of Employee in the provision of
services or performance of duties under this Agreement. This indemnification
section shall survive and continue in full force and effect after the expiration
of this Agreement.

                                   ARTICLE VII
                                   ARBITRATION

      Except for the provisions of Sections 5.1, 5.2 and 5.5 dealing with issues
of nondisclosure, noncompetition and cooperation, with respect to which the
Company reserves the right to petition a court directly for injunction or other
relief, any controversy of any nature whatsoever, including but not limited to
tort claims or contract disputes, between the parties to this Agreement or
between Employee, his heirs, executors, administrators, legal representatives,
successors and assigns and the Company and its affiliates, arising out of or
related to the Employee's employment with the Company, any resignation from or
termination of such employment and/or the terms and conditions of this
Agreement, including the implementation, applicability and interpretation
thereof, shall, upon the written request of one party served upon the other, be
submitted to and settled by arbitration in accordance with the provisions of the
Federal Arbitration Act, 9 U.S.C. ss.ss.1-15, as amended. Each of the parties to
this Agreement shall appoint one person as an arbitrator to hear and determine
such disputes, and if they should be unable to agree, then the two arbitrators
shall choose a third arbitrator from a panel made up of experienced arbitrators
selected pursuant to the procedures of the American Arbitration Association (the
"AAA") and, once chosen, the third arbitrator's decision shall be final, binding
and conclusive upon the parties to this Agreement. Each party shall be
responsible for the fees and expenses of its/his arbitrator, and the fees and
expenses of the third arbitrator shall be shared equally by the parties. The
terms of the commercial arbitration rules of the AAA shall apply except to the
extent they conflict with the provisions of this paragraph. It is further agreed
that any of the parties hereto may petition the United States District Court for
the Western District of Texas, San Antonio Division, for a judgment to be
entered upon any award entered through such arbitration proceedings.
