What Hubdoc does, by its own pages
Hubdoc’s help centre describes it as a data capture tool that reads key details such as contact, date and amount from documents and creates transactions in QuickBooks or Xero, while storing the documents. You email bills and receipts to your Hubdoc address or upload photos from the mobile app, then publish them; you reconcile in your accounting software afterwards.
The help centre also says Hubdoc is set up as a separate organisation with a 30-day trial, and that the organisation becomes read-only after the trial until payment details are added. Xero’s UK site separately describes its own smart document capture, included on its small business plans, which scans documents and prepopulates records. Xero users should compare both options before adding a separate tool.
