Making Tax Digital Software - MTD Compatible | WDI Billing

Making Tax Digital Software That Keeps Your Books Yours

Looking for Making Tax Digital software that does what HMRC asks without handing over control of your business data? WDI Billing is MTD compatible software built around a simple idea: your records live with you, and nothing is ever sent to HMRC until you decide it's ready. We call it Prepare mode - you press file, nothing streams to HMRC automatically.

Most accounting platforms are built to push data outward as fast as possible. We built WDI Billing the other way round: digital records that satisfy the letter of Making Tax Digital, an approval step you control, and a filing button that only fires when you click it.

What HMRC-recognised software actually needs to do

Making Tax Digital doesn't require you to hand real-time visibility of your finances to HMRC - it requires digital record-keeping, a digital link between your records and your return, and submission through HMRC-recognised software. That's it. Anything beyond that is a product choice made by the software vendor, not a legal requirement.

The "digital link" requirement trips a lot of businesses up. In practice it means that once a transaction is entered digitally, it has to flow through to your return without being manually retyped or copied into a spreadsheet cell by cell - a screenshot pasted into a bridging tool, or figures keyed in from a paper printout, breaks that chain. WDI Billing keeps every invoice, expense and receipt in one continuous digital record from the moment it's captured to the moment it's filed, so the link is never broken and you're never left wondering whether a workaround counts.

WDI Billing is built to meet exactly what's required:

  • Digital records of income and expenses, kept continuously rather than reconstructed at deadline time
  • A genuine digital link from source records through to the figures submitted, with no manual re-typing that breaks the chain
  • Direct, HMRC-recognised submission when you're ready to file
  • Full audit trail so you (or your accountant) can see exactly what was sent and when

Prepare mode: you press file, nothing streams automatically

This is the part most MTD compatible software gets wrong. Many platforms treat continuous background syncing to the tax authority as a feature. We treat it as your decision to make. In WDI Billing, invoices, expenses and receipts are captured and organised in the background, but they stay in your account, under your control, until you actively choose to submit.

That's Prepare mode: everything is ready to file the moment you want it filed, but nothing leaves your account before then. If you want to review, correct, or simply sit on a period before submitting, you can. Your books stay yours - not a live feed to a government system.

In practice that looks like this: a landlord or sole trader raises invoices and logs expenses as they go through the quarter, WDI Billing organises them into the shape HMRC expects, and at quarter end the figures sit in Prepare mode waiting for a final check. You can amend a miscategorised expense, add a missing receipt, or simply leave it a few extra days while you double-check something with your accountant - none of that is possible if your software has already streamed the data across in the background.

Built for MTD for Income Tax and MTD for VAT

WDI Billing covers both major strands of the programme, so you're not stuck stitching together two tools:

  • MTD for Income Tax software - digital record-keeping and quarterly updates for sole traders and landlords brought into scope as MTD for Income Tax (MTD ITSA) rolls out. Full detail on who's affected and when is in our MTD qualifying income guide.
  • MTD VAT filing - if you're VAT-registered, submission is already mandatory under Making Tax Digital. See our dedicated MTD VAT software page for how we handle VAT returns specifically.

Whichever strand applies to you, the underlying promise doesn't change: Prepare mode keeps the filing decision with you, every quarter, every return.

Is your business affected by Making Tax Digital?

Making Tax Digital has been rolling out in phases, with different start points depending on your qualifying income and whether you're VAT-registered. Rather than guess at figures here, we've laid out the exact thresholds and dates in our guide to MTD qualifying income, and a broader explainer in what is Making Tax Digital if you're starting from scratch.

If you're a sole trader specifically, our Making Tax Digital for sole traders guide walks through what changes for you in plain terms - and how a tool built around Prepare mode makes the transition far less disruptive than switching to always-on accounting software.

What good MTD compatible software should include

Beyond the bare legal minimum, we think MTD software should actually make your life easier. Compliance is the floor, not the whole product - so alongside the core record-keeping and filing mechanics, WDI Billing includes:

  • Receipt and document scanning, with AI reading the detail if you opt in - or fully manual entry if you'd rather it worked without AI at all
  • Clean exports at any time, so your data is never locked inside our platform
  • Accountant access on your terms - a "break-glass" login you grant and can revoke, not a permanent open door
  • No per-invoice fees or usage penalties for running your business the way you run it

Records, Prepare, File: three modes, one product

WDI Billing runs on three modes so you're never forced into more automation than you want:

  • Records - straightforward digital bookkeeping, nothing submitted anywhere
  • Prepare (the default) - your figures are organised and ready to file, but submission is a deliberate action you take
  • File - the actual, user-triggered submission to HMRC through recognised software

Whether you only need MTD-compliant record-keeping today or you're ready to file quarterly updates, you move between modes without switching software or re-entering data. Moving from a spreadsheet, a shoebox of receipts, or another accounting platform doesn't mean starting your records from zero either - you can bring historic data in and export everything back out again at any point, so choosing WDI Billing is never a one-way door.
