MTD compatible software is a genuinely confusing category to shop in, largely because HMRC's own recognised software list treats dozens of very different tools as interchangeable entries on a single page. A full accounting platform and a receipt-capture app can sit side by side on that list, as though choosing between them were the same kind of decision. It is not, and it is a different question again from whether bridging software is still enough for a given client in the first place.
The confusion clears up once you stop treating "MTD software" as one purchase decision and start treating it as two. This is the two-layer model that most accountants have not consciously applied, even though it is how their actual software stack already works in practice.
Why the HMRC recognised software list does not help you choose
HMRC's list exists to confirm which software can technically communicate with its systems, not to rank software by suitability, usability, or fit for a particular type of practice. A tool appearing on that list tells you it meets the minimum bar for compatibility. It tells you nothing about whether it will actually reduce your workload or your clients'.
That is precisely why so many practices find the list overwhelming rather than useful. Scrolling through it looking for "the best one" is the wrong question, because the list contains tools built for entirely different jobs.
The two-layer model
Most practices, whether they have named it this way or not, already run MTD compliance through two distinct layers of software.
Layer one: the accounting software. This is the system of record, Xero, QuickBooks, FreeAgent, or Sage, that holds the ledger, generates the return figures, and submits them to HMRC through MTD-compatible APIs. This is the layer most conversations about "MTD software" are actually about, and it is the decision most practices have already made, often years before MTD for Income Tax became relevant.
Layer two: the capture layer. This is how the underlying transaction data, receipts, invoices, bank feeds, actually gets into that accounting software in a form that is accurate and digitally continuous. This layer is where most of the day-to-day admin burden actually sits, and it is the layer practices most often leave unexamined, relying on manual entry or a client's own inconsistent habits rather than a dedicated tool.
Separating these two decisions matters because they are evaluated against completely different criteria, and conflating them leads practices to either overpay for accounting software chosen for capture features it handles poorly, or underinvest in capture because they assumed the accounting software's built-in tools were good enough.
How to evaluate the accounting software layer
If this decision is already made for your practice, and for most it is, the main question is whether it is being used correctly for MTD purposes rather than whether to switch. Confirm the software's MTD for Income Tax functionality is properly enabled for each client, including property income clients specifically, not just the VAT-related MTD features many practices have had running for years already. Confirm quarterly update submissions are set up correctly and that the software's digital record-keeping meets the continuity requirement, not just the final figures being accurate, which assumes clients are already properly registered and authorised in the first place.
For practices genuinely evaluating a change, the criteria that matter most are integration depth with the tools your practice already relies on, pricing that scales sensibly with client count rather than penalising growth, and how well the software handles the specific complexity of your typical client, property income, multiple income streams, or straightforward sole trader accounts, since these vary significantly between platforms.
How to evaluate the capture layer
This is the decision worth spending more time on, because it is where the actual admin savings live, and where the difference between tools is largest.
Extraction accuracy on real client receipts, not a vendor's demo receipts, is the first thing to test. Run your own messiest client receipts, crumpled, faded, photographed at an angle, through any tool before committing, since accuracy on clean sample data tells you little about how it performs on what your clients actually submit, the same due-diligence approach behind the accountant's checklist for choosing a new receipt scanning tool.
Digital continuity, specifically whether the capture layer keeps an unbroken digital link from the original receipt through to the figure that lands in your accounting software, is the requirement most tools glaze over in their marketing but that MTD actually cares about. A tool that requires manual re-entry at any point breaks that chain.
Integration with your specific accounting software, checked directly rather than assumed from a badge on the vendor's website, since integration quality varies from a genuinely native connection to a clunky CSV export that still needs manual work at the other end.
Client-side friction, how easy the tool makes it for your clients to actually submit receipts, matters as much as anything on this list, because a capture layer clients do not use consistently provides no benefit regardless of how accurate its extraction is.
Putting the two layers together
Once you have settled the accounting software layer, usually already done, evaluate capture layer options specifically for how well they sit alongside it rather than in isolation. Receiptflow is built as the capture layer that works alongside any MTD-compatible accounting software, extracting and categorising client receipts and feeding the result straight into your existing platform, rather than asking a practice to replace a system that is already working.
This is the practical answer to the confusing HMRC list: you are not choosing one MTD compatible tool. You are choosing an accounting platform (if you have not already) and a capture layer, evaluated separately, against the criteria that actually matter for each, in the same way thinking of leaving Dext prompts a fresh look at what to check in any tool.
Receiptflow is MTD-ready and integrates with your existing accounting software. Start a free trial and see how the capture layer decision looks once it is separated from the accounting software you have already chosen.
