MTD VAT Software That Puts You in Control of Every Submission

If you're VAT-registered, Making Tax Digital for VAT isn't optional - HMRC has required digital records and digital submission for VAT returns since the rules came into force. What is optional is how much control you keep over your own data along the way. WDI Billing is MTD VAT software built around a simple principle: your books stay yours, and nothing reaches HMRC until you decide it's ready.

Most VAT return software treats compliance as something that happens to you in the background. We built ours the other way round. You keep digital records, you prepare your VAT return whenever you like, and you submit VAT return HMRC data only when you actively press file. No silent syncing. No surprise submissions. No black box.

Three modes: Records, Prepare, File

WDI Billing separates bookkeeping from submission into three clear modes, so you always know exactly what state your VAT data is in:

• Records - your invoices, receipts and transactions are logged and categorised in one MTD-compliant digital record, satisfying the digital links requirement without any data leaving your account.
• Prepare - the default mode for every VAT-registered user. Your VAT return is calculated, checked and ready to review - line by line, box by box - entirely offline from HMRC's systems.
• File - only when you actively choose to submit. This is the one step that talks to HMRC, and it happens because you clicked the button, not because a background job ran overnight.

This matters because VAT-registered businesses are already inside the MTD mandate - there's no "wait and see" here. But being compliant doesn't mean handing over a live feed of your finances. Prepare mode means you can build, correct and review your VAT return as many times as you need before that one deliberate act of filing.

Built for HMRC-recognised VAT submission

WDI Billing connects directly to HMRC's Making Tax Digital service to submit your VAT return in the correct format, whichever VAT scheme you're on - standard, flat rate, or cash accounting. The software handles the digital link chain from source transaction through to submitted return, so you're covered on the digital records requirement as well as the filing requirement.

Because everything is prepared and reviewed before it's sent, you can catch a miscoded expense, a missing invoice, or a duplicate entry before it ever becomes part of a live submission - not after.

Submit your VAT return with a clear audit trail

Every VAT return you file through WDI Billing leaves a complete, exportable trail: what was in the return, when it was prepared, when it was reviewed, and when it was filed. If your accountant needs to check a quarter's figures, or you need to demonstrate your working to HMRC, that trail is yours to export at any time - not locked inside a proprietary format you can't take with you.

Who MTD VAT software is for

This page is for any VAT-registered business - sole trader, partnership, or limited company - that needs to keep digital VAT records and submit returns through MTD. If you haven't registered for VAT yet, or you're approaching the point where you might need to, our VAT registration UK guide walks through the registration process and what changes once you're in the VAT system.

If you're managing VAT alongside wider bookkeeping and Self Assessment or Income Tax obligations, our broader Making Tax Digital software page covers how WDI Billing handles MTD across both VAT and Income Tax.

Still on spreadsheets? You don't have to give them up

If you already track VAT figures in a spreadsheet and just need the digital link to HMRC, you don't need to rebuild your whole process. Our MTD bridging software lets you keep the spreadsheet and use WDI Billing purely for the compliant submission step.

Receipts and expenses, without losing control

VAT returns are only as accurate as the records behind them. WDI Billing includes document ingestion so you can photograph or upload receipts and invoices as they arrive, with optional AI-assisted categorisation - entirely opt-in. Prefer to enter everything manually? The software works exactly the same way without AI switched on. Either way, nothing about your receipts is sent anywhere until you choose to include it in a prepared return.

Bring your accountant in, on your terms

Need a second pair of eyes on your VAT return before you file? WDI Billing supports accountant and advisor access - a break-glass style login that lets your accountant review, query or adjust records without you handing over your main account credentials or giving them standing access you didn't ask for.

Clean exports, no lock-in

Your VAT records and prepared returns can be exported cleanly at any time, including formats your accountant will recognise. If you ever decide to move to another package, or hand records to a new advisor, you take everything with you. There's no fee per invoice and no penalty for wanting your own data in your own hands.
