Approving bills and duplicate detection
Approving a bill is the moment it becomes real: it posts to your ledger as a payable expense, GST included, dated by the invoice date.
What approval sets in motion
The expense appears in your Profit & Loss and the payable in You owe on the dashboard.
The GST input credit flows into the right return period.
When the payment later appears in your bank feed, Reconcile proposes the match against the approved bill — so the expense is never double-counted. See Matching payments to invoices.
Duplicate detection
The Inbox flags documents that look like something you have already processed — same supplier, same amount, same or similar date. This catches the classic cases: a supplier emailing the invoice twice, a statement uploaded after the invoice, or the same receipt photographed and forwarded.
Handling a duplicate flag
Open both documents and compare references — two genuinely different bills can coincidentally match on amount.
If it is a true duplicate, dismiss the document rather than approving it. Dismissed documents are kept, not deleted.
If it is legitimately a second identical charge (a repeating subscription, say), approve it — the flag is advisory.
