CassKai vs Dext: a specialised receipt-OCR tool, or full accounting with OCR built in?

Dext excels at one thing: capturing and reading documents (receipts, supplier invoices) at volume, then pushing the data into an accounting tool. We embedded expense-receipt OCR directly into CassKai (Tesseract.js + GPT-4o AI), with accounting, invoicing, e-invoicing and cash management behind it — to avoid a capture tool on one side and the accounting on the other.

Careful, verifiable comparison

Dext offers may change. Non-public pricing or edition-specific features are flagged as such; always verify the official quote or documentation before deciding.

Overview

Dext (formerly Receipt Bank, renamed in 2020) is a highly regarded specialised capture and pre-accounting tool, particularly among Anglo-Saxon chartered-accounting firms and bookkeepers. Its core business: capturing documents (receipt photo, email forwarding, drag-and-drop), reading them via OCR / AI (supplier, amount, tax, date), then publishing the extracted data into an accounting tool (Xero, QuickBooks, Sage...). Dext also handles supplier rules, automatic matching and a multi-client dashboard for firms. On this specific niche, it is one of the best products on the market, with a reputedly very high extraction accuracy.

Key positioning point: Dext is not an accounting suite. It is a capture / pre-accounting building block that sits upstream of an accounting tool. You do not keep a general ledger, produce a balance sheet, or file VAT in Dext: you feed the tool that does the accounting. Dext is therefore almost always complementary, not a frontal replacement for an accounting tool.

What this implies in 2026:

CassKai, published by Noutche Conseil, embeds capture inside the platform: expense-receipt OCR uses Tesseract.js in the browser for text extraction, complemented by a GPT-4o AI layer for categorisation, anomaly detection and entry pre-filling. Behind it, you have full accounting (4 standards: PCG, SYSCOHADA, IFRS, SCF), customer invoicing, France e-invoicing (PPF / PA) and UEMOA, cash management, payroll (15 countries) and CRM. The idea is not to claim parity with Dext's multi-client capture throughput in a practice, but to cover an SME's needs without having to plug a separate capture tool onto its accounting.

Strengths

CassKai

  • Natively embedded expense OCR (Tesseract.js + GPT-4o AI): capture a receipt and the accounting entry is pre-filled and categorised in the same tool, with no connector to a third-party software.
  • All-in-one platform: capture lives next to accounting, invoicing, e-invoicing, cash management, payroll and CRM. Dext only does capture; CassKai does capture AND the suite.
  • 4 native accounting standards (PCG, SYSCOHADA, IFRS, SCF): Dext is centred on Anglo-Saxon Xero / QuickBooks; CassKai handles France AND the OHADA zone in the same product.
  • Franco-African coverage (France + 33 countries) with native Mobile Money and UEMOA e-invoicing — ground Dext does not address at all.
  • Transparent EUR SaaS pricing (29 / 79 / 199), full suite included, with no per-document billing and no extra accounting subscription to stack.

Dext

  • Document-capture specialist: extraction accuracy reputed among the highest on the market (supplier, amount, tax, date), on receipts and supplier invoices at volume.
  • Built for practices: multi-client dashboard, supplier rules, approval workflows and productivity designed to process hundreds of documents a day across multiple files.
  • Strong accounting integrations: mature connectors with Xero, QuickBooks, Sage and others, making it easy to slot Dext into an existing stack.
  • Maturity and reliability: a product installed for years across tens of thousands of firms and businesses, with a proven mobile capture app.
  • Deliberately complementary approach: Dext plugs upstream of an existing accounting tool, an advantage for those wanting to keep their accounting and just industrialise document capture.

Target Audience

Dext remains an excellent choice if your need is precise: you are a chartered-accounting firm or a bookkeeper processing hundreds of documents a day across many client files, already tooled up on Xero / QuickBooks / Sage, and you want the best capture tool to feed your accounting. On that ground, Dext is hard to beat and its multi-client throughput is a real strength.

CassKai is built for you if:

Let us be honest: for very large-scale document capture in a multi-file practice, Dext is a specialist and CassKai does not aim to match its raw capture throughput. For an SME wanting OCR plus all the accounting in a single tool, CassKai takes the lead.

Migration Guide

Replacing (or avoiding) a Dext + accounting-software combo with CassKai typically happens in 3 steps over 3 to 6 weeks:

  1. Step 1 - Assessment (week 1): we identify what Dext captures today (expense receipts, supplier invoices) and where that data lands (Xero, QuickBooks, Sage...). The goal is to bring capture + accounting into a single tool, CassKai.
  2. Step 2 - Accounting data migration (weeks 2-3): export the general ledger, trial balance, customer / supplier sub-ledgers and fixed assets from your current accounting tool (CSV format). CassKai's import wizard proposes mapping to the target chart of accounts (PCG, or SYSCOHADA for an OHADA subsidiary). Documents already captured in Dext can be exported and kept as archives.
  3. Step 3 - Capture switchover (weeks 3-6): your staff start photographing their receipts and expense reports directly in CassKai (Tesseract.js OCR + GPT-4o AI), which pre-fills and categorises the entry. You stop Dext once the switchover is confirmed, and cancel the replaced accounting software subscription in parallel. Keep Dext / old-software archives for the legal retention period (10 years in France).

Our support team assists you free of charge during the 30-day trial to frame the accounting migration and test the OCR on your real documents.

Frequently Asked Questions

Is Dext a competitor of CassKai or a companion?

Dext is above all a complementary tool: it captures documents and feeds an accounting tool, it does not keep the books itself. CassKai includes expense-receipt capture (OCR) within a complete accounting platform. So if you currently use Dext + an accounting tool, CassKai can replace both at once for an SME. We stay honest: for multi-client capture throughput in a practice, Dext is a specialist and we do not claim 1:1 parity on that specific aspect.

What OCR technology does CassKai use for expense receipts?

CassKai uses Tesseract.js in the browser for text extraction from receipts and invoices (a proven open-source OCR engine), complemented by a GPT-4o AI layer to structure the data (supplier, amount, tax, date), categorise the expense, detect anomalies and pre-fill the accounting entry. The advantage: everything happens in the platform, the entry is directly integrated into your accounting, with no export or connector to a third-party tool. Dext, for its part, has a mature, highly accurate extraction engine dedicated to capture — its core business — but then publishes to an external accounting tool.

Is CassKai's OCR as accurate as Dext's?

Let us be transparent: Dext has made document extraction its sole core business for years, with accuracy reputed among the best on the market on very high volumes and varied receipt formats. CassKai's OCR (Tesseract.js + GPT-4o AI) is designed for an SME's everyday needs — expense receipts, supplier invoices on a rolling basis — and the pre-fill remains manually verifiable before posting. For an SME, this is amply sufficient and the native integration offsets the difference in specialisation. For a practice processing tens of thousands of heterogeneous documents a month, Dext keeps the edge on raw extraction performance.

Does Dext cover the OHADA zone and Mobile Money?

No. Dext is centred on the Anglo-Saxon ecosystem (Xero, QuickBooks) and does not address the SYSCOHADA standard, UEMOA standardised invoicing, or Mobile Money (M-Pesa, MTN MoMo, Wave, Orange). For an SME or group with operations in Cote d'Ivoire, Senegal, Cameroon or elsewhere in the OHADA zone, these are structural gaps. CassKai handles these obligations natively and covers France + 33 African countries.

How much does CassKai cost versus Dext plus an accounting tool?

CassKai is billed at 29 / 79 / 199 EUR per month (public pricing), OCR and full suite included. With Dext, you add Dext (billed per document volume or per client for practice plans, pricing not publicly disclosed in EUR) PLUS the accounting software Dext publishes to. The cumulative total of a Dext + accounting combo often exceeds a single platform for a comparable scope. As always, compare the total monthly cost of your stack (all tools) to CassKai's pricing, not the price of an isolated tool.

Can I keep Dext and use CassKai only for accounting?

Technically, nothing stops you from continuing to capture documents in Dext and then entering / importing into CassKai. But the point of CassKai is precisely to avoid that stacking: with expense-receipt OCR built in, you generally no longer need a separate capture tool for an SME's needs. We do not offer a native two-way sync connector with Dext — we are an integrated alternative, not a companion. For very high-volume practices attached to Dext, parallel use (Dext export → CassKai import) remains possible while evaluating.
