Your VAT100 return from the books, not a spreadsheet

Every invoice, bill, credit note and advance feeds the return for the period you choose. Open any figure to see the documents behind it, then file with confidence.

  • All nine VAT100 boxes
  • Rates by date, so older documents keep their own rate
  • Warnings for documents dated in a filed period

Know where you stand, every day

The executive dashboard shows revenue, expenses, profit, cash, receivables and payables at a glance, with charts for the year and an action centre for what needs attention.

Made for the UK

Local tax rules, already set up

The UK edition comes with the UK's tax rates, return layout and chart of accounts, so you start working on day one.

VAT 20%, 5% and 0%

Standard, reduced and zero rates per line on every invoice, bill and credit note.

VAT100 figures

All nine boxes for the period, built from your books, with drill-down to the documents behind each figure.

Rates that update themselves

Tax rates are stored with the date they start, so every document keeps the rate of its own date. New official rates arrive as a file digitally signed by Baats LLC and apply from their start date. You can also add your own rate.

Card payments on invoices

Connect Stripe, Checkout.com, PayPal, Square or Mollie and let customers pay invoices online.

Reports for your accountant

Profit and loss, balance sheet, cash flow and trial balance, exported to Excel or PDF.

Payroll basics

Employee records, payroll runs posted to the books and salary slips by email. PAYE and RTI submissions are not included yet.

How does the free trial work?

Download the edition you want and install it. It runs with every feature for 15 days. After that your books stay readable and printable, and you enter a product key to keep working.

Do I need to host it myself?

The web edition runs on your own server or hosting with Node.js 22.5 or newer. The Windows edition installs on a PC in a few clicks. If you need help choosing or setting up, talk to us.

Can I manage more than one company?

Yes. Each company gets its own set of books with its own users, package and product key, all from one installation.

Can I import my existing data?

Yes. Use the Excel template to import customers, customer invoices, suppliers, supplier bills and expenses, and enter opening balances per account, customer and supplier.
