Onzli application
Onzli
Prepare, check and submit your UK VAT returns from the accounting data you already keep, with each step explained as you go.
£6.50 per accepted return, including VAT. No subscription.
You pay nothing to sign up. New businesses are guided through setup straight away.What you get
Everything you need to file with confidence
- A guided setup that takes you from sign-up to your first return, one step at a time.
- A read-only connection to ERPNext: pick your company from a list, and nothing in your books is ever changed.
- Onzli finds the accounts that hold your VAT from how your own invoices use them, and asks you to confirm them.
- You decide once what each tax template means for VAT, with a reason. Anything that depends on an undecided template is held back, never guessed.
- All nine boxes calculated and checked before anything is filed, with a clear list of anything that needs your attention.
- Approval by a second person by default, or by one person with extra safeguards.
- Submission to HMRC with the declaration, HMRC's receipt kept for you, and a safe way to check the outcome if HMRC's answer is delayed.
- Roles for everyone in your business, two-step verification for sensitive actions, and a VAT receipt for every payment.
