Problem
VAT becomes difficult when the invoices do not reconcile.
Missing purchase invoices distort the quarterly result.
Repeated invoice numbers and mixed VAT rates require careful review.
Manual categorisation makes Model 303 totals hard to trust.
Last-minute reconciliation leaves little time to fix exceptions.

FAQs
Questions specific to vat and model 303.
Does the IVA workflow support Model 303?+
Yes. Zottio includes a Model 303-focused VAT review workflow for quarterly preparation.
Can Zottio detect duplicate invoices?+
Zottio stores invoice numbers and can make repeated-number review visible, but full duplicate-detection logic is still a product gap.
Are VAT rates categorised automatically?+
Zottio extracts VAT-rate data from documents and shows it for review; exceptions stay visible before totals are trusted.
Does Zottio submit VAT automatically?+
No. The product prepares and explains the draft position; users or advisors review filing decisions.
