How it fits together
One loop, four sides.
Every integration does one of four jobs. Nothing here is a widget you have to wire up yourself.
Money in
Bank and payment feeds land as categorised transactions, matched to invoices.
Paperwork in
Receipts, invoices and meeting notes arrive from wherever you already keep them.
Ask Finn anywhere
Same accountant, same books, whichever window you happen to have open.
Filings out
Returns go straight to HMRC and Companies House, after you approve them.
