Veryfi Scanned PDF Accuracy Issues: Why Financial Documents Need Purpose-Built OCR
Veryfi claims 99.56% accuracy on receipts, but accountants working with scanned bank statements face a different reality. Character misinterpretation, missing decimal points, and faint text extraction failures create cascading errors that break reconciliation workflows.
Veryfi's OCR Limitations with Scanned Financial Documents
Veryfi's OCR engine performs well with high-quality receipt images but encounters systematic problems when processing scanned bank statements. The pattern of failures reveals limitations in handling the specific challenges of financial document processing.
Character Misinterpretation on Low-Quality Scans
Users report consistent OCR errors with blurry or distorted images. The system extracts 7 as 1, or 5 as 3, causing transaction amounts to be recorded incorrectly. A $750 wire transfer becomes $150, breaking bank reconciliation entirely.
The problem compounds when decimal points blur. OCR misplaces extracted information, turning $1,234.56 into $123,456 or $12.3456. These aren't minor transcription errors—they're fundamental failures that require manual verification of every scanned statement.
Missing Faint Text and Incomplete Data Extraction
When text is too faint or unclear due to poor scan quality, Veryfi's OCR skips those portions entirely. Transaction descriptions vanish. Account numbers become partial strings. Date fields extract as empty values.
One documented case: business cards with faint colored text caused Veryfi OCR to lose complete words. For bank statements, this means missing check numbers, incomplete payee names, and dropped transaction rows that only surface during manual review.
300 DPI Requirement Creates Workflow Friction
Veryfi documentation specifies 300 DPI as optimal for PDF processing. This technical requirement creates immediate problems for accounting firms receiving client documents. Small business owners scan statements at default settings (often 150-200 DPI). Banks email PDF statements at web-optimized resolutions below 300 DPI.
The result: accountants must either reject client documents and request rescans (adding days to turnaround time) or accept lower accuracy rates that eliminate the value of OCR automation. Neither option works for month-end close workflows.
Reduced Accuracy for Multi-Currency Bank Statements
Veryfi's documentation states: "less accuracy can be expected for documents in different languages and currencies." For accounting firms handling international clients or businesses with foreign bank accounts, this limitation breaks the product's core value.
A CPA processing statements from Canadian and US entities must accept degraded accuracy on half their documents. There's no published metric for how much accuracy drops—just the acknowledgment that the system performs worse when bank details appear in non-English languages or non-USD currencies.
15-Page Document Limit Requires Manual Splitting
Veryfi's API restricts single document processing to 15 pages maximum. Business checking accounts frequently generate 20-30 page monthly statements. Processing these requires splitting PDFs manually before upload, then reassembling results afterward.
Custom account configurations can raise this limit, but require contacting support and potentially additional charges. For bookkeepers processing 50+ client statements monthly, the page limit adds friction to every conversion workflow.
No Feedback Loop for Accuracy Improvement
Users report concerns about the lack of a feedback mechanism to report actual data and improve OCR performance. When Veryfi misreads a transaction amount or misses a line item, there's no structured way to correct the error and train the system.
This creates a static accuracy ceiling. The same types of errors repeat across similar document formats because the OCR engine doesn't learn from its mistakes. Accounting firms process the same bank's statements monthly, encountering identical extraction failures each cycle.
Why Scanned PDFs Fail with General-Purpose OCR
General OCR engines optimize for text documents—contracts, articles, forms with clean layouts. Financial statements present different challenges that require specialized training data and extraction logic.
Tabular Data Misalignment
Bank statements arrange transactions in columns: date, description, debit, credit, balance. Low-quality scans cause column boundaries to blur. General OCR reads left-to-right, extracting "01/15" then "$1,234.56" without understanding which value belongs to which column. The description text flows into the amount field.
Decimal Point Recognition Failures
Financial amounts require precise decimal placement. A blurred period becomes ambiguous. General OCR doesn't know that $1,23456 is impossible—it extracts whatever characters appear. Purpose-built financial OCR applies validation rules: amounts must have exactly two decimal places, commas appear every three digits from the right.
Header and Footer Contamination
Every page of a multi-page statement repeats the same header (account number, date range, bank name) and footer (page numbers, disclaimers). General OCR extracts these as transaction rows. The result: duplicate account numbers appearing as transaction descriptions, page numbers mistaken for amounts. Cleaning this requires custom post-processing logic.
Multi-Line Transaction Descriptions
Bank statements often wrap long descriptions across multiple lines. "ELECTRONIC DEPOSIT / PAYROLL / COMPANY NAME INC" spans three lines. General OCR treats each line as a separate transaction. Financial-trained OCR recognizes continuation patterns and concatenates multi-line descriptions into single transaction records.
The Image Quality Trap
Veryfi's 300 DPI requirement isn't arbitrary—it's the threshold where character recognition becomes reliable for general OCR models. Below that resolution, the difference between "7" and "1" collapses to a handful of pixels. The decimal point disappears entirely.
But requiring 300 DPI PDFs misunderstands how accounting firms receive documents. Clients email screenshots of mobile banking apps. Businesses forward PDF statements generated at 72 DPI for web viewing. Older statements exist only as physical copies scanned at whatever settings the office copier defaults to. Rejecting these documents means rejecting the reality of bookkeeping workflows.

How Zera OCR Handles Low-Quality Scanned PDFs
Zera OCR doesn't reject low-quality documents—it's designed for them. The system trains on 2.8 million bank statements spanning every quality level accountants encounter: crisp digital PDFs, faded photocopies, smartphone photos, ancient scanned statements from file cabinets.
Financial Document Specialization
Training exclusively on financial documents means Zera OCR understands what's possible in this domain. It knows transaction amounts must balance to opening and closing balances. It recognizes that descriptions follow bank-specific patterns. When character recognition returns ambiguous results, the system applies financial logic to resolve conflicts.
Multi-Pass Extraction Strategy
Zera OCR runs multiple extraction passes at different confidence thresholds. The first pass captures clear, high-confidence text. Subsequent passes focus on problematic regions using enhanced preprocessing: contrast adjustment, noise reduction, edge sharpening. Faint text that disappears in the first pass becomes readable in later passes.
Decimal Point Validation
Amount fields undergo post-extraction validation. The system checks that currency amounts follow standard formatting: optional thousands separators every three digits, exactly two decimal places. When OCR returns malformed amounts, validation rules correct the structure. $1234.5 becomes $1,234.50. $12.345 triggers re-extraction of that specific field.
Bank Format Recognition
Rather than requiring templates for each bank, Zera OCR identifies statement layouts dynamically. It recognizes Chase's transaction table structure differs from Bank of America's. It knows Wells Fargo uses different header terminology than Citi. This format awareness guides extraction logic without manual configuration.
No Page Limits, No DPI Requirements
Zera Books processes bank statements of any length. The 30-page business checking statement uploads as a single PDF. The system automatically segments pages, extracts transactions, and assembles a complete transaction history. No manual splitting. No configuration requests.
Document resolution becomes irrelevant. A 72 DPI screenshot from a mobile banking app processes with the same accuracy as a 600 DPI scan. The OCR engine applies appropriate preprocessing based on detected image quality rather than rejecting low-resolution inputs.
This matches the reality of bookkeeping workflows. Clients send whatever documents they have in whatever format they received them. The OCR system adapts to documents rather than forcing documents to meet technical requirements.
"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."
