What is professional services accounting?

Professional services accounting is bookkeeping and reporting for firms that sell expertise: consultants, agencies, architects, law and design firms. It tracks revenue and costs by client and project, separates billable from non-billable spend, and shows margin by engagement. Zeni's AI Accountant codes activity as it lands, and your Zeni team closes the books each month.

Your standards

Every number comes with its reasoning.

Each AI suggestion arrives with its reasoning and confidence, so you and your Zeni team can see why a contractor bill or software charge landed on a project. Approval rules route bills to the right partner, and nothing changes in a closed period. Change history on every entry keeps reviews simple.
