One place for every client and every invoice
Design studios, marketing teams, development shops and creative agencies juggle a mix of billing: project quotes, deposits, milestone invoices, monthly retainers and the odd extra request. When each client has a different currency, contact and set of terms, a spreadsheet quickly stops being enough.
BooksBat keeps your clients, your services and your billing history together. Send branded quotes that clients accept online, turn them into invoices with one click, and put retainers on a recurring schedule. The dashboard shows what is outstanding, what is overdue and which clients bring in the most, and because BooksBat is full small business accounting, your expenses, bills and profit and loss live in the same account.

- Connect your own tools with the REST API, or let an AI assistant create and send invoices through the MCP server.
Billing habits that keep agency cash flowing
- Quote before you start. An accepted quote is a clear record of scope and price that both sides can point to.
- Take a deposit on new projects. It confirms the client is committed and covers early costs.
- Invoice retainers on the same day each month. A predictable invoice is easier for a client's finance team to process.
- Keep scope changes separate. Quote extra work as its own line or quote, so the retainer stays clean.
- Check the aging report weekly. Catch overdue invoices early, while a friendly reminder still works.
