For consultants and firms, your inventory is time. We track billable work, unbilled WIP, retainers, and client invoicing, so your revenue is recognized correctly and your profit per client is clear.
Clean books are the difference between running your professional services business on real numbers and running it on guesswork. We give you accurate, up to date bookkeeping and clear reporting, so every decision, from pricing to hiring to your next investment, rests on what is really happening in your business, not a rough estimate at year end.
Why it is different
When you sell time and expertise, revenue timing matters. Work is often done before it is billed, retainers are paid before work is done, and profit varies a lot by client. Getting this wrong makes your numbers misleading.
We track billable work and unbilled WIP, handle retainers and deferred revenue correctly, keep client invoicing tight, and report profit by client, so your books reflect the real economics of your practice.

Professional services accounting guide
Consultants, architects, engineers, IT firms, therapists, accountants and other professional services firms sell time and expertise. The key numbers are not inventory or margins on goods. They are billable hours, realization, collections and profit per client.
Time worked but not yet invoiced is real value. Tracking unbilled time by client and invoicing on a fixed schedule (weekly, biweekly or at milestones) is one of the fastest ways to improve cash flow.
Advance retainers are earned as work is performed, so they sit in deferred revenue or client deposits until then. Law firms holding client money must follow their state’s trust account (IOLTA) rules. Those funds are never the firm’s income and must be reconciled to each client’s ledger.
Service firms often do the work weeks before they’re paid. A weekly AR aging review, clear payment terms and online payment links shorten that gap. Use the free AR aging tool and the invoice generator.
Many firm owners operate as an S corporation. S corp owners who work in the business must take a reasonable salary through payroll before distributions. Your books should separate owner salary, distributions and reimbursed expenses clearly. See payroll services.
Classes in QuickBooks or tracking categories in Xero let you see revenue and direct costs by partner, office or service line, so you can price new work with confidence. For freelancers and solo consultants, see our bookkeeping for consultants guide.
