Purchases & expenses — common questions
What's the difference between an expense and a purchase bill?
Expenses are for spend settled immediately from cash or bank. Anything bought on credit — pay-later terms, supplier accounts — is a purchase bill, which tracks the payable until you settle it. OneBooks does both.
Can I photograph receipts instead of typing them?
Yes — upload the photo in the AI assistant. It extracts the supplier, date, lines and Sales tax exactly as printed and shows you a draft purchase; one tap posts it through the same accounting engine as manual entry.
How do purchase returns work?
Record a debit note against the bill: cost and Sales tax reverse correctly, the payable adjusts, and any refund is an explicit separate step — so the paper trail stays complete.
Can I route a bill line to a specific account?
Yes — each purchase line can post to the asset or expense account you choose, so equipment doesn't get buried in cost of goods and your reports stay meaningful.
