What it does for you

  • Finds any invoice or bill

    One question reaches every company - your AI app reads their invoices and bills and finds them by customer, supplier, amount or date.

  • Sends invoices

    Creates invoices, estimates and credit notes, and sends invoices and estimates, in the right company.

  • Records bills and expenses

    Bills, expenses with their receipts, and payments - kept the way your program keeps them.

  • Explains bank lines

    Explains the lines on your bank feed in FreeAgent and records bank entries in Xero.

  • Shows who owes you

    Totals by customer and supplier, overdue invoices and the cash forecast.

  • Read only where you want

    Each company has its own read-only switch: on, Multi Books changes nothing there.

Your books

  • Each company has its own read-only switch - on, every write there is refused before FreeAgent or Xero is asked.

  • Multi Books never moves money - it makes no payment and charges no card. An invoice it approves in Xero is collected only by a Direct Debit you set up there.

  • The words of every record are screened for prompt attacks before they reach your AI app, and the words of everything it writes before they reach your program.

  • We keep no copy of your books. They are read from FreeAgent or Xero each time your AI app asks.

  • Made by Lumman Ltd, London.
