A DMC can help you fill in an income and expenditure form to work out where your money is being spent each week or month. This will leave an amount to be split between the companies you owe money to. The DMC will contact the companies for you to explain your arrangement. They will then make an Offer of Payment which is affordable for you.
Once accepted, you will only need to make one payment to the debt management company. They will send payments to your creditors on your behalf after collecting the funds from you as arranged with them.
This is a long-term way of repaying your debts and can also impact your credit file. It is worth remembering you can do the above yourself directly with the companies you are in debt to. Most companies will be more than happy to arrange an affordable payment plan with you rather than having to deal with a debt management company.
