Dext Alternative: Why UK Accounting Firms Are Switching to AI Agents
Dext (formerly Receipt Bank) has been a staple in UK accounting practices for years. It solved a real problem: getting invoice and receipt data out of paper and PDFs and into the accounting software without manual typing. For many firms, it was the first step toward automating bookkeeping.
But the technology landscape has shifted significantly since Dext first launched. What counted as automation five years ago — scanning a receipt and extracting the total, date, and supplier — is now just one small piece of the puzzle. Practices that rely on Dext still spend substantial time reviewing extractions, correcting VAT codes, fixing nominal account coding, and handling everything that happens after data capture.
This article looks at why firms are exploring alternatives, what the current options are, and what to consider if you are thinking about making a change.
What Dext does well
Credit where it is due. Dext built a solid product for document capture. The mobile app for photographing receipts works well. The email forwarding feature is convenient for clients who receive invoices digitally. The supplier database is extensive, which helps with recognition accuracy on common UK suppliers. And the Xero integration, while basic, is reliable.
For firms that only need to capture data from invoices and receipts and push it to the ledger as draft transactions, Dext does the job. The problem is that most firms need more than that.
Where Dext falls short
VAT coding accuracy
This is the most common complaint we hear from practices switching away from Dext. Dext extracts the VAT amount from an invoice reasonably well. But extracting the number is different from determining the correct VAT treatment.
Is this standard-rated, reduced-rated, zero-rated, or exempt? Is it a reverse charge service from overseas? Is it a CIS transaction that needs a different treatment? Dext relies heavily on supplier-level rules, which means if a supplier provides both standard-rated and zero-rated goods, you need to manually check every invoice. For practices handling complex VAT scenarios across multiple clients, the correction overhead is significant.
It stops at data capture
Dext captures data from documents. That is where its job ends. But bookkeeping involves much more: bank reconciliation, working papers, prepayments, accruals, fixed assets, and financial close. If you use Dext, you still need separate tools or manual processes for everything that comes after invoice capture.
This creates an odd workflow where you automate one part of the process (getting data from paper to the ledger) but still do everything else by hand. The time savings are real but limited.
Per-client pricing at scale
Dext charges per client. For a small practice with 10–20 clients, the cost is manageable. But as you scale to 50, 100, or 200 clients, the per-client model becomes expensive. Practices processing high volumes have told us their annual Dext bill can run into the tens of thousands — a significant overhead for what is essentially a data capture tool.
Limited learning
Dext gets better at recognising specific supplier formats over time, but it does not learn the contextual patterns that make a bookkeeper effective. A human bookkeeper knows that when Client A buys from Supplier X, it always goes to “Motor Expenses”, but when Client B buys from the same supplier, it goes to “Distribution Costs”. Dext does not make these contextual connections at the client level without manual rule setup.
What AI-native alternatives offer
The newer generation of bookkeeping tools uses large language models and AI agents rather than OCR with machine learning. The practical difference is significant.
End-to-end bookkeeping, not just capture
Briefcase, for example, handles the full bookkeeping workflow: invoice capture, data extraction, VAT determination, chart of accounts coding, bank reconciliation, working papers, prepayments, accruals, and fixed assets. The AI does not just read the document — it does the bookkeeping.
Contextual learning
AI agents learn from your corrections at the client level. When you correct a VAT code or reclassify a transaction, the AI learns that pattern for that specific client. Over time, it needs fewer corrections and can handle more transactions autonomously. This is fundamentally different from setting up supplier rules — the learning is continuous and contextual.
Connolly Accountancy switched from Dext to Briefcase and now has 65% of transactions auto-published without any human review, with 99% accuracy. Their team processes work four times faster than they did with their previous workflow.
Autopilot publishing
When the AI is confident in its output, it can publish directly to Xero or QuickBooks without human review. This is the step change that OCR tools cannot offer. Instead of reviewing every transaction, you only review the ones the AI flags as uncertain. For many firms, this reduces review volume by 50–70%.

Comparing the alternatives
If you are looking to move away from Dext, here are the main options and how they compare.
Briefcase
Best for: Practices that want to automate end-to-end bookkeeping, not just data capture. AI agents handle everything from invoice capture to financial close.
Key differences from Dext: Full bookkeeping automation (not just capture), contextual AI that learns per client, Autopilot auto-publishing, integrated bank reconciliation, working papers, and VAT handling. Wilson Partners achieved 97% field-level accuracy and 3x processing efficiency.
Integrations: Xero and QuickBooks.
AutoEntry (Sage)
Best for: Practices already in the Sage ecosystem looking for a like-for-like Dext replacement at a lower price point.
Key differences from Dext: Credit-based pricing (can be cheaper at lower volumes). Now tightly integrated with Sage. Accuracy is generally comparable to Dext, though some firms report it is slightly less reliable on complex documents.
Limitations: Same fundamental limitations as Dext — it is a data capture tool, not end-to-end bookkeeping. Sage integration focus means less investment in Xero compatibility.
Hubdoc (Xero)
Best for: Practices that want basic document capture included with their Xero subscription (Hubdoc is included free with Xero).
Key differences from Dext: Free with Xero. Good for fetching supplier documents automatically (utility bills, bank statements). Less capable on ad-hoc invoice extraction than Dext.
Limitations: Limited extraction accuracy compared to dedicated tools. No learning or AI capabilities. Xero-only.

Switching from Dext is simpler than most firms expect. Here is what the process actually looks like.
Your data stays in Xero/QuickBooks
All your historical transactions, supplier records, and chart of accounts live in your accounting software, not in Dext. When you connect a new tool to the same Xero or QuickBooks account, it has access to the same data. There is no export/import process needed.
Redirect document uploads
The main workflow change is redirecting where documents go. Instead of emailing invoices to your Dext address or uploading through the Dext app, you send them to the new tool. For client-facing workflows (where clients photograph receipts), this means updating the app they use.
The AI learns fast
AI-native tools like Briefcase learn from your existing ledger data in Xero or QuickBooks. They do not start from zero — they analyse your historical transactions to understand your coding patterns, supplier mappings, and VAT treatments from day one. Most firms see good accuracy within the first batch of invoices, with significant improvement over the first few weeks as the AI processes more documents and receives corrections.
Run both tools in parallel initially
There is no reason to make a hard switch. Many firms run both tools in parallel for 2–4 weeks, processing the same invoices through both to compare accuracy and workflow. This eliminates risk and gives your team time to adjust. Once you are confident in the new tool, cancel the old one.
Frequently asked questions
What is the best alternative to Dext for UK accountants?
It depends on what you need. If you want full bookkeeping automation including VAT coding, bank reconciliation, and auto-publishing to Xero or QuickBooks, Briefcase is the most comprehensive option. If you want a like-for-like document capture replacement, AutoEntry or Hubdoc (free with Xero) are the closest alternatives.
Can I migrate from Dext to another tool easily?
Yes. Your historical data lives in Xero, QuickBooks, or Sage — not in Dext. Switching means connecting the new tool to the same accounting software and redirecting your document upload workflow. There is no data migration required. Most firms run both tools in parallel for a few weeks before fully switching.
Why are accounting firms leaving Dext?
Common reasons include: per-client costs adding up at scale, VAT coding still requiring heavy manual correction, the tool only handling data capture rather than end-to-end bookkeeping, and wanting AI that learns from corrections rather than requiring manual rule setup. Firms processing high volumes find the review overhead with Dext still significant.
How does AI-agent bookkeeping differ from Dext?
Dext uses OCR and machine learning to extract data fields from documents. You then review and correct each extraction before publishing. AI agents understand documents in context — they determine VAT treatment, map to the correct nominal accounts, learn from your corrections, and can auto-publish when confident. The result is less human review, higher accuracy over time, and end-to-end automation beyond just document capture.
Getting started
If you are evaluating Dext alternatives, the best test is to run a real comparison on your actual client data. Start a free Briefcase trial, connect one Xero or QuickBooks client, and process a batch of invoices. Compare the accuracy, VAT handling, and workflow against what you get from Dext.
