Needs your reviewWhy this looks like a business expense
Review the suggestion and amend if anything doesn’t match your records.
Nothing is filed without your approval.

xontax helps you build a reviewable workflow earlier, so you’re not stitching together categorisations at the last minute.

Connect the bank feed and start reviewing decisions while the data is fresh.
Less manual mapping
AI proposes matches with explanations, then uncertain items are surfaced for review.
