Accounting software for contractors varies in pricing based on your needs, volume, company size, or how many users will access the software. Some companies don’t offer flat-rate or upfront pricing; rather, you’ll need to contact the company to get custom pricing.  For the companies that do offer upfront pricing, expect to pay around $12 to $49 per month, with some software costing several hundred dollars per month. Most companies charge per user and bill monthly, while others require an annual commitment. Also keep in mind that some companies might charge a one-time implementation fee, which can be as high as $30,000.
