Bank lines booked to your accounts, on your own computer.
bonfyre books learns from the lines a client has already categorised and books a new month from that. The lines it is unsure of go to a local model, which sees how similar lines were booked before. Transactions never leave the computer.
One month of 1,500 lines

What is in it, and what is not
Working now
Learning from a categorised history, booking a bank or card export, a local model for the unsure lines, review for anything still unclear, and a receipt per line.
Not yet
Connecting to a bank or to the client's accounting software. Lines arrive as an export and leave as a CSV.
The books stay theirs
A booked line is a suggestion the client or their bookkeeper can change; a held line is not booked.
Run it yourself
Books on your own machine
