Hubdoc Transaction Categorization Errors: Why Manual Review Is Required in 2025
Hubdoc's OCR struggles with fonts, misclassifies credit notes as invoices, and requires accountants to manually review every transaction before publishing to QuickBooks or Xero. Here's what you need to know about categorization accuracy.
If you're an accountant or bookkeeper using Hubdoc, you've likely encountered the same frustrating workflow: upload a document, wait for OCR processing, then spend significant time in the Review tab manually verifying and correcting transaction categories before publishing to your accounting software.
While Hubdoc markets itself as an automation tool, the reality is that users must manually review every transaction to catch categorization errors. According to user reports and official Hubdoc documentation, common issues include font reading failures, credit notes misclassified as invoices, multi-currency categorization mistakes, and incorrect coding on supplier invoices.
This article examines the specific categorization errors Hubdoc users encounter, why manual review is mandatory, and how AI-powered alternatives like Zera Books achieve 99.6% accuracy without constant human intervention.
The 7 Most Common Hubdoc Categorization Errors
Font Reading Failures Force Manual Edits
Hubdoc's OCR technology cannot accurately read certain fonts, particularly stylized or condensed typefaces common in bank statements and invoices. Users report that documents with non-standard fonts require "tedious manual edits" to correct misread amounts, dates, and transaction descriptions. This is especially problematic for credit unions and regional banks that use custom statement templates.
Credit Notes Misclassified as Invoices
When Hubdoc detects a credit note, it displays a yellow warning flag asking users to "review the prediction and publish it manually." However, if a supplier is set to auto-sync, credit notes are often pushed through to Xero as invoices instead, creating incorrect accounting entries that must be manually reversed. Users must constantly monitor for these misclassifications.
Multi-Currency Transactions Frequently Miscategorized
Accountants managing clients with multiple currencies report that Hubdoc "improperly handles some currencies," especially when integrated with QuickBooks. The system may apply incorrect exchange rates, categorize foreign currency transactions under wrong accounts, or fail to distinguish between domestic and international transactions. This requires manual currency validation for every multi-currency statement.
Cannot Tag Transactions by Last Four Digits
Hubdoc doesn't allow users to tag bank accounts with the last four digits of credit or debit cards used in transactions. As a result, the system "often can't push transactions to the right account" automatically. Users must manually verify and reassign transactions to the correct account, particularly problematic for businesses with multiple credit cards.
Supplier Invoices Come Through with Incorrect Coding
User reports consistently mention that "invoices can come through with incorrect coding," meaning vendor invoices are assigned to wrong expense categories or incorrect GL accounts. This happens because Hubdoc relies on Supplier Rules that must be manually configured for each vendor—and even then, categorization accuracy depends on the quality of OCR extraction.
Requires "User Input to Push Transactions to Xero Correctly"
Multiple user reviews state that Hubdoc "usually needs some user input to push transactions to Xero correctly." This means the promised automation isn't fully automatic—accountants must intervene to verify categories, correct amounts, and ensure proper account mapping before publishing. The Review tab becomes a mandatory checkpoint, not an optional verification step.
Users Manually Check Every Document Instead of Using Auto-Sync
Many accountants have disabled auto-sync entirely and chosen to "manually check every document" because fixing categorization errors after auto-publishing takes more time than reviewing upfront. As one user reported: "Some have decided to manually check every document instead of using autosync, or spend time fixing mistakes if transactions were categorised incorrectly."
Why the Review Tab Is Mandatory in Hubdoc
Hubdoc's official workflow documentation explicitly states that users must "head to the Review tab to check data accuracy" before publishing documents to accounting software. This isn't presented as an optional quality control step—it's a required part of the process because the system cannot guarantee categorization accuracy.
"Users need to head to the Review tab in Hubdoc to check data accuracy and ensure each item is correctly categorized. This verification step is essential before publishing documents to accounting software."
— Hubdoc Documentation & User Reviews
The Review tab workflow involves:
- Visual verification: Checking that OCR correctly read amounts, dates, and descriptions
- Category correction: Manually reassigning transactions to correct expense categories
- Credit note verification: Responding to yellow warning flags for credit notes
- Multi-currency validation: Confirming exchange rates and currency handling
- Account mapping: Ensuring transactions route to correct bank accounts
For accountants managing 20-30 clients with monthly bank statements, this manual review process consumes hours every month-end—defeating the purpose of automation software.

Conclusion: Manual Review vs. Intelligent Automation
Hubdoc's categorization errors—font reading failures, credit note misclassifications, multi-currency mistakes, and incorrect supplier coding—create a mandatory manual review workflow that consumes 15-30 minutes per statement. For accounting firms managing 20-50 clients, this adds up to 5-15 hours per month spent fixing automation that doesn't actually automate.
The fundamental issue is that Hubdoc's OCR-first approach focuses on data extraction, not categorization intelligence. The system can read a document, but it can't understand accounting context—which is why the Review tab remains mandatory.
AI-powered alternatives like Zera Books eliminate this bottleneck with machine learning trained specifically on accounting workflows. The result: 99.6% accuracy out of the box, 2-4 minute processing per statement, and categorized data that's ready to import without manual verification. For firms looking to actually automate their bank statement workflows—not just digitize them—the technology difference is substantial.

From Manual Review to AI-Powered Accuracy
Ashish Josan · Manager, CPA at Manning Elliott
"My clients send me all kinds of messy PDFs from different banks. This tool handles them all and saves me probably 10 hours a week that I used to spend on manual entry."
The Challenge
As a Manager at Manning Elliott overseeing bookkeeping for multiple small business clients, Ashish was spending 2-3 hours per client per month just on data entry—retyping transactions from bank statements into Excel, formatting them, then importing to QuickBooks or Xero.
