Dext Expense Capture and Bookkeeping API
Dext (formerly Receipt Bank) expense capture and bookkeeping automation REST API for accounting firms, bookkeepers, and SMBs to automate receipt scanning, expense extraction, and accounting software synchronization. Enables AI agents to manage receipt and invoice image submission for OCR extraction automation, handle extracted line item data retrieval (supplier, amount, tax, date) for expense categorization automation, access client document inbox management for accounting firm client data automation, retrieve bank statement import and transaction matching for bookkeeping automation, manage supplier rules and category assignment for automated expense coding automation, handle expense report approval workflow for corporate expense management automation, access VAT/GST tax code extraction for tax compliance automation, retrieve integration with QuickBooks, Xero, and Sage for direct accounting software posting automation, manage client portal and team access for accounting practice management automation, and integrate Dext with accounting software and corporate card platforms for end-to-end expense-to-ledger automation.

⚡ Reliability
Best When
An accounting firm, bookkeeper, or SMB wanting AI agents to automate receipt capture, OCR extraction, expense categorization, and accounting software synchronization using Dext's bookkeeping automation platform.
Avoid When
OCR EXTRACTION ACCURACY FOR AUTOMATED POSTING: Dext OCR extraction accuracy varies by document quality, language, and supplier format; automated accounting software posting without human review of extracted data creates incorrect ledger entries for poor-quality receipts; implement confidence score threshold review before automated posting for unreviewed extraction results. VAT/GST PARTIAL EXEMPTION FOR MULTI-JURISDICTION BUSINESSES: Automated VAT code extraction by Dext may not correctly handle partial exemption or mixed supply businesses; automated VAT posting without accountant review of tax code assignment creates VAT return errors; partial exemption businesses require manual tax code review even with automated extraction. GDPR DATA PROCESSOR ROLE FOR CLIENT DOCUMENT STORAGE: Dext stores client receipt and invoice images as data processor; accounting firms using Dext API for client data processing must maintain data processing agreements with clients; automated client document ingestion without GDPR data processing agreement creates controller-processor compliance gap for EU clients.

Known Gotchas
- ⚠ OCR PROCESSING ASYNC WEBHOOK PATTERN: Dext document OCR extraction is asynchronous; document submission returns a document ID but extracted data is not immediately available; automated data pipelines must listen for webhook events for extraction completion before fetching results; synchronous document-to-data pipelines that poll immediately after submission will receive incomplete extraction
- ⚠ DUPLICATE DOCUMENT DETECTION TOLERANCE: Dext duplicate detection uses image hash comparison; automated receipt ingestion from multiple sources (email forwarding, mobile app, API) can create duplicate documents if the same receipt is submitted via multiple channels; implement document hash deduplication in automated ingestion layer before Dext submission to avoid duplicate accounting entries
- ⚠ SUPPLIER RULE TRAINING DATA DEPENDENCY: Dext automated category assignment relies on supplier rules configured per client; automated expense categorization for new suppliers without existing rules requires fallback category; automated posting of uncategorized items creates accounting software entries in default catch-all category requiring manual reclassification
- ⚠ ACCOUNTING SOFTWARE POSTING REVERSAL COMPLEXITY: Dext posts to accounting software (Xero, QuickBooks) as published transactions; automated posting errors require manual reversal in the accounting software — Dext API does not support automated reversal of already-posted transactions; implement pre-posting validation before automated accounting software publication
- ⚠ MULTI-CURRENCY FOREIGN EXCHANGE RATE SOURCE: Dext applies exchange rates for multi-currency receipts from its own rate feed; automated multi-currency expense reporting must reconcile Dext's applied rate with the corporate card FX rate to avoid P&L currency variance; automated multi-currency posting without rate source reconciliation creates accounting restatement risk for companies with material foreign currency expenses
