AI-powered receipt and invoice scanning has become one of the most practical applications of machine learning for UK accounting practices. By eliminating manual data entry for supplier invoices, employee expenses, and bank statements, these tools free up significant time in bookkeeping workflows. This review covers the four main tools in the UK market: Dext, AutoEntry, Hubdoc, and Xero's built-in capture features.

Why document capture tools matter for practices

Manual data entry is expensive, error-prone, and dull. For a practice managing bookkeeping for 20 SME clients, even modest savings per client per month add up to meaningful efficiency gains across the year. The economics are compelling when you consider that a junior bookkeeper spending two hours per client per month on data entry costs far more than a document capture subscription.

Beyond cost, there is an accuracy argument. AI OCR tools, trained on millions of invoices, can extract structured data from a standard UK VAT invoice faster and with fewer errors than a tired human entering data manually. The remaining error rate, while real, is concentrated in predictable categories: handwritten documents, poor-quality photographs, and unusual layouts. Once you know where errors occur, you can design review processes to catch them.

The tools in this category also solve a client relationship problem. Chasing clients for receipts is a perennial frustration for bookkeepers. Mobile capture apps, which allow clients to photograph and submit receipts via their smartphone, significantly reduce the friction and improve the quality and timeliness of document submission.

Dext: the market leader reviewed

Dext (rebranded from Receipt Bank in 2021) is the dominant document capture tool for UK accounting practices. It integrates with Xero, QuickBooks Online, Sage Business Cloud, FreeAgent, and several other platforms. The core workflow is straightforward: clients or practice staff upload documents via the mobile app, web browser, email, or direct bank feed connection; Dext extracts the data; reviewed and approved items are pushed to the accounting platform.

What Dext does well

Accuracy on standard UK VAT invoices is high. The tool reliably extracts supplier name, invoice date, invoice number, net amount, VAT amount, VAT number, and currency. The supplier learning feature means that once you have confirmed the correct nominal code for a supplier, Dext applies it automatically to future documents from that supplier. The history-based learning reduces the review burden significantly after the first few months with a new client.

The multi-currency support is strong. For practices with clients dealing with overseas suppliers or operating internationally, Dext handles a wide range of currencies and applies the relevant exchange rate. The bank statement extraction feature, which can process PDF bank statements and push transactions to the accounting platform, is particularly useful for clients who are slow to set up bank feeds.

Dext limitations

Dext is priced per client, and for practices with a large number of smaller clients, the costs can accumulate. The pricing structure suits practices managing substantive bookkeeping for a portfolio of SMEs but is harder to justify for clients who generate only occasional documents. The interface, while functional, has received mixed feedback from practitioners who find it less intuitive than competing tools.

Pricing starts at approximately £15–£20 per client per month for practice accounts, with volume discounts available. Dext offers practice pricing plans that include a set number of client connections, which can reduce the per-client cost at scale.

AutoEntry: the Sage-native option

AutoEntry was acquired by Sage in 2019 and is now tightly integrated with the Sage product family. For practices primarily using Sage 50 or Sage Business Cloud, AutoEntry is the natural first choice for document capture. The integration is deeper than most third-party connections, which reduces the configuration overhead and makes reconciliation more straightforward.

AutoEntry uses a credit-based pricing model rather than a subscription. Credits are consumed when documents are processed, and unused credits roll over. This model works well for practices with variable document volumes and avoids the situation where you are paying for capacity you are not using.

The accuracy is broadly comparable to Dext for standard UK documents. AutoEntry supports receipt capture, invoice capture, and bank statement processing. The mobile app is functional, though Dext's app is generally considered more polished. AutoEntry also supports supplier statement reconciliation, which can save time for clients with high transaction volumes.

Hubdoc: the Xero-bundled option

Hubdoc is included at no additional cost with Xero Starter, Standard, and Premium plans and with Xero Partner plans. For practices using Xero as their primary platform, this makes it a compelling starting point, as there is no additional subscription cost for the core functionality.

Hubdoc's differentiating feature is its ability to connect directly to supplier and bank portals to collect statements automatically. Rather than waiting for clients to submit documents, Hubdoc can pull bank statements, utility bills, phone bills, and other recurring documents directly from the source. For practices with clients who are consistently late in providing documents, this automated collection can transform the bookkeeping workflow.

The limitation is that the OCR accuracy is generally considered slightly lower than Dext or AutoEntry for complex documents. For straightforward UK invoices with standard layouts, this rarely matters. For clients with unusual document types or who deal with many overseas suppliers, the accuracy difference may justify paying for a dedicated capture tool.

Xero Capture and built-in features

Xero's own mobile app includes a capture feature that allows clients to photograph receipts directly, which are then matched against bank transactions in Xero. For clients who generate a relatively small volume of receipts and are comfortable using the Xero app, this built-in feature may be sufficient without any additional tool.

The built-in feature does not match the capability of dedicated capture tools for high-volume or complex use cases. It lacks the batch processing, bank statement extraction, and portal connection features that Dext and Hubdoc provide. However, for simple client profiles, avoiding an additional subscription is a reasonable choice.

Accuracy rates and supported formats

All four tools support JPEG, PNG, and PDF input. JPEG and PNG photographs work best when the document is well-lit, held flat, and captured from directly above. PDF files, particularly those generated digitally rather than scanned, typically yield the highest accuracy.

Typical accuracy rates for well-photographed, standard UK VAT invoices are 90–97% across all four tools for the key numeric fields. Accuracy drops for handwritten documents (which none of the tools handle reliably), receipts from non-standard formats (such as till receipts on thermal paper), and documents in languages other than English.

All four tools allow manual correction of extracted data, and the learning mechanisms mean that corrections feed back into future predictions for the same supplier. Establishing clean initial coding decisions is therefore important; errors made early in a relationship with a tool tend to persist unless actively corrected.

Which tool suits which type of firm

  • Xero-primary practices managing SME bookkeeping: Start with Hubdoc (included in your Xero plan) and evaluate whether the accuracy and feature set is sufficient. If volume grows or you need bank statement processing at scale, consider Dext as an upgrade.
  • Sage-primary practices: AutoEntry is the natural fit. The integration depth and the credit-based pricing model work well for Sage-focused firms.
  • Mixed-platform practices with high document volumes: Dext's multi-platform integration and volume pricing make it the most practical option. The per-client pricing is worth paying for the reliability and the breadth of integrations.
  • Sole practitioners with a small client base: Xero Capture or Hubdoc will handle the volume adequately. Avoid paying for dedicated capture tools until the volume justifies the cost.

All four vendors offer free trials or demo accounts. Running a controlled comparison with a sample of your real client documents is the most reliable way to assess accuracy for your specific context before committing to a subscription.
