Better than QuickBooks
QuickBooks charges monthly fees to store your data on their servers, buries core invoicing features behind upsells, and forces you into their ecosystem. Booker delivers more capable invoicing — three-level tax logic, automatic lifecycle tracking, fractional quantities, per-line service dates — with an AI assistant that answers business questions in plain English. QuickBooks doesn't do that at any price tier.
Smarter invoicing
Create professional invoices with automatic sequential numbering. Pull line items from a product and service catalog with default pricing, or type custom entries. Three-level tax logic (customer × product × line item) handles complex tax scenarios that QuickBooks oversimplifies. Invoices move through a clear lifecycle — Draft, Sent, Partial, Paid — with automatic overdue detection. Print directly from the browser or save as PDF.
Customer & payment tracking
Maintain a complete customer database with multiple service addresses per customer, tax-exempt flags, and organizational groups. Record cash, check, or other payments with automatic status transitions and overpayment prevention. Customers are soft-deactivated, never deleted, so invoice history is always preserved.
AI business assistant
A built-in AI chat assistant with read-only access to the full database. Ask plain-English questions — "How much did we bill the Johnsons last year?" "Show me all overdue invoices over $500." "Revenue by month for 2025?" — and get instant answers grounded in real data, never hallucinated.
Deploy your way
Run Booker as a standalone Windows desktop app with a one-click installer — no technical knowledge required. Or deploy on a local office server with Docker for multi-user access. Or host in the cloud for remote access from anywhere. Your data, your infrastructure, your choice.
QuickBooks migration
Migrating from QuickBooks? Booker includes a one-time import pipeline that reads QB Excel exports and brings in customers, invoices, line items, and payments with intelligent FIFO payment matching. Years of historical data preserved in minutes.
