You approve every entry.

Books drafts and reads. You decide what goes into your books.

Nothing recorded without you
An invoice is issued and a payment recorded only when you reply with the exact words. A note or a photo is never approval.
GST rates come from you
You choose the rate for each sales category. Books may suggest one from your approved list; it never sets it.
Every number has a source
Your message, a saved record, the receipt image or the issued invoice. You can always see where a figure came from.
Reports from your ledger
Sales, GST charged, dues and bank reports are calculated from double-entry books, with their dates shown.
