Why Most Practices Get This Decision Wrong
Using a checklist for choosing a receipt scanning tool is not something most accountants think they need. You watch a demo, the extraction looks sharp, the price seems reasonable, and you move forward. It is only six months later, when you are manually correcting supplier names, chasing clients to re-upload blurry photos, and realising the Xero sync is not quite what it appeared in the demo, that the real cost becomes clear.
This is not a rare story. Receipt scanning software looks similar across providers at a surface level. The differences that actually matter - OCR accuracy on handwritten receipts, how duplicates are handled, what happens when a client submits the same receipt twice do not tend to come up in sales calls unless you ask directly.
This checklist gives you the 10 questions to ask before you commit, whether you are evaluating your first tool or switching away from one that has not worked out. If you have not shortlisted candidates yet, our review of the five main UK options is a reasonable place to start.
The 10 Questions to Ask Before You Sign Up
1. What is the actual OCR accuracy rate on real documents?
Every receipt scanning tool claims high accuracy. What you need to know is accuracy on your clients' documents: crumpled till receipts, faded thermal paper, photos taken in poor lighting, handwritten mileage logs.
Ask the vendor to process a batch of real documents from your client base during the trial. Compare the extracted data against the originals. A tool that performs at 97% on clean, high-resolution invoices may drop to 80% on the receipts your clients actually submit. At 80% accuracy, you are spending more time correcting data than you would have spent entering it manually.
Receiptflow's extraction is built to handle exactly these edge cases, including handwritten documents and damaged receipts. See how the extraction engine works.
2. How does the tool handle duplicate receipts?
Clients submit the same receipt twice more often than you might expect: once by photo, once by email forward, occasionally both via the mobile app and the web uploader. If the tool does not catch this automatically, you end up with duplicate transactions in Xero or QuickBooks that your team has to identify and remove manually.
Ask specifically: does the tool flag potential duplicates before posting? Can you configure the sensitivity threshold? Is this included in the pricing tier you are being quoted, or is it a higher-tier add-on?
Receiptflow detects and flags duplicate submissions automatically, without any configuration required. Find out how Receiptflow handles duplicate detection.
3. How deep is the accounting software integration?
There is a significant difference between a tool that connects to Xero and a tool that integrates well with Xero. The former pushes data across; the latter maps supplier names to existing contacts, applies the correct nominal codes based on your chart of accounts, handles VAT treatment correctly for both standard and zero-rated purchases, and syncs without creating reconciliation problems.
During the trial, run a batch of test transactions through the integration and check what actually lands in your accounting software. Do not rely on the integration description in the product documentation.
Receiptflow's Xero and QuickBooks integrations are built for accountants, not just end users. Explore the integrations.
4. Is the pricing per client or per transaction volume?
This matters more than the headline price. A tool priced per transaction can become significantly more expensive as client volumes grow, or during busy periods like year-end when submission rates spike. A per-client model is usually more predictable for a growing practice.
For context: Dext charges around £391 per month for 50 clients. Receiptflow's Essential plan covers 50 clients at £150 per month less than half the cost, with no feature bloat to navigate. If you are comparing tools, work out the annual cost at your current client count and your projected count in 12 months, not just the monthly headline figure.

5. What happens to your data if you leave?
This question does not come up often enough. Before you migrate client data into any platform, ask: can you export all documents and extracted data if you decide to switch? In what format? Is there an export fee?
For practices dealing with MTD for ITSA and expanding digital record-keeping requirements, the ability to access and export historical transaction data is not optional. Make sure you have a clear answer before you sign.
6. How long does onboarding actually take?
Vendors tend to describe onboarding optimistically. Ask for the average time from sign-up to a practice being fully operational, based on real client data rather than the quickest case they can name. Ask specifically about client-side onboarding: how are clients invited, how do they submit documents, and what support is available if they struggle with the upload flow?
The onboarding experience for your clients is part of the product. A tool your clients find confusing will generate support requests that cost your team time. See how Receiptflow onboards practices and their clients.
7. What is the actual support response time?
Check the support SLA before you need it. Is support available by phone, or email only? What is the average first response time? Is there a dedicated account contact for practices above a certain size?
It is worth checking review platforms like Capterra or G2 for comments specifically about support quality. Vendors can describe their support offering however they like; customers will tell you what it is like when something goes wrong.
8. Can you test it with a pilot group of clients before rolling it out?
A tool that works well for straightforward expense receipts may struggle with specific document types common to certain industries: construction subcontractor invoices, mileage claims, foreign currency receipts, fuel cards. Before committing your whole client base, run a pilot with 5 to 10 clients whose document types represent the breadth of what you handle.
If the vendor does not offer a trial period long enough to run a meaningful pilot, treat that as a signal. Receiptflow offers a free trial with no credit card required, giving you time to test with real clients before making a decision.
9. Is the interface something your clients will actually use?
Client adoption is the hidden variable in every receipt scanning implementation. The most accurate extraction engine is worthless if clients continue emailing you PDFs because they find the app too confusing to use consistently.
If possible, get two or three clients to try the mobile submission flow before you make a decision. Watch where they hesitate. Notice what they have to ask you about. A clean, simple interface that clients adopt quickly is worth more in practice than a feature-rich one they avoid.
Receiptflow is designed with client simplicity as a core principle, not an afterthought. Try out and experience the simplicity yourself..
10. What does the product roadmap look like for the next 12 months?
Receipt scanning software sits at the intersection of OCR technology, accounting software APIs, and HMRC's digital requirements. All three are changing. Ask the vendor what features are planned for the next year, and more importantly, ask how they handle updates to integrations when Xero or QuickBooks changes its API.
A vendor with a clear, actively developed roadmap is a meaningfully different proposition from one where the product has been largely static for the last two years.
How to Structure Your Evaluation
Once you have your answers, score each question on a simple 1 to 3 scale: 1 for a weak or evasive answer, 2 for an adequate answer, 3 for a strong, specific answer with evidence. Add up the scores. Any tool scoring below 20 out of 30 warrants serious scrutiny before you commit.
If two tools are closely matched, weight questions 1 (OCR accuracy), 3 (integration depth), and 9 (client usability) more heavily. These three factors drive the majority of the ongoing time cost in running a receipt scanning workflow. Everything else is easier to work around.
A Note on Switching Costs
If you are already on a tool that is not working, the calculus around switching is worth thinking through carefully. The switching cost is real: data migration, client re-onboarding, the time to reconfigure coding rules. But the ongoing cost of staying on a poor-fit tool is also real, and it compounds every month.
The practices that get this decision right the second time tend to be the ones that slow down the evaluation process rather than speeding it up. A two-week proper trial with real documents and a small pilot group costs a few hours. A 12-month contract with the wrong tool costs considerably more.
If you are at that point now, Receiptflow's free trial is a reasonable place to start the comparison. No credit card, no commitment, and you can bring in real client documents from day one.
