The $3,000 AI Invoice Desk for Small Businesses

It reads every invoice that lands in your inbox, checks it against your vendors and past invoices, logs the clean ones as ready to pay and holds anything that looks wrong.

Free. We'll email you a link to confirm. Privacy

  • Every invoice is read and logged within minutes of arriving, with the vendor, the amount and the due date.
  • Duplicates, new vendors, changed bank details and unusual amounts are held, with the reason in plain English, before anyone can pay them.
  • One email each morning shows what is due this week and what is waiting for your decision.
