Payment Tracking

Always Know What You're Owed

Accounting clients often run on monthly retainers with additional charges for quarterly filings and tax season work. The invoice dashboard shows every client and their payment status — Draft, Pending, Paid, or Overdue — so you always know which engagements are settled and which need follow-up.

Why Accountants and CPAs Choose ServiceInvoicing

Generic invoicing tools don't understand retainer billing, engagement types, or the documentation your clients expect. ServiceInvoicing does.

Engagement-Specific Fields Built In

Capture service type, billing period, entity type, tax year, and returns filed without squeezing critical details into a notes field.

Retainer and Project Billing

Bill monthly retainers, quarterly filings, and one-time engagements as separate line items — with clear descriptions your clients can reconcile against their own records.

Professional PDFs Your Clients Expect

Your invoices look clean and authoritative — with your firm name, contact details, and all engagement information on one well-organized document.

Works from the Office or Remotely

Create invoices from client meetings, update payment status from your phone during tax season, and review annual revenue from anywhere you work.

Built to Scale With Your Practice

Start free with your first client. Invite staff accountants as you grow. Add custom schemas for new service lines as your practice expands.

Complete Client and Engagement History

Every client, every engagement, every invoice is stored and searchable — so you can pull up prior period invoices or resend a PDF at tax time in seconds.
