Why Onzli
Why pay every month for something you do four times a year?
HMRC requires VAT-registered businesses to file through Making Tax Digital software. Much of that software is sold as a monthly subscription, even though most businesses file only once a quarter.
Onzli charges per return instead. If you file four times a year, you pay for four returns, and nothing in between.
How it works
Three steps, and you stay in control
- Step 1
Connect
Connect your ERPNext books, or import your VAT figures from a CSV file. Then link HMRC once, with your own Government Gateway sign-in.
- Step 2
Check
See all nine boxes before anything is sent. If something is unclear, Onzli asks you rather than guessing.
- Step 3
Submit
Approve, make the declaration and submit. You keep HMRC's receipt, and we charge £6.50 only once HMRC accepts it.
Pricing

Choose annualBuilt to be trusted
Your tax return, handled carefully
Read-only by design
Onzli reads your accounting data. It never creates, changes or deletes anything in your books.
You approve every return
Preview the figures first. Nothing reaches HMRC until a return is approved and you make the declaration.
Bring your bookkeeper
Invite your accountant or bookkeeper with their own login and role. Ask for a second person to approve if you want one.
Secure and recorded
Two-step verification, encrypted connections, data kept separate for every business, and a record of every action.
Questions
Common questions
Does Onzli work with my accounting software?
Connects to Xero. Onzli also connects directly to ERPNext. Using different software? Import your VAT figures from a CSV file instead.
What happens if HMRC rejects my return?
You are not charged. You see HMRC's reason, put it right, and submit again.
What do I need to get started?
Your VAT registration number and the Government Gateway sign-in you use for HMRC. You connect HMRC once, inside Onzli.
Can my accountant or bookkeeper use it?
Yes. Invite them with their own login and choose what they can do. You can require a second person to approve each return.
Can I cancel?
Pay as you file has nothing to cancel: you only pay per accepted return. On an annual plan, you can cancel any time and we refund what you paid, minus £6.50 for each return already filed.
