Hubdoc's 1,000 Document Daily Upload Cap
Hubdoc enforces a hard limit of 1,000 documents per 24-hour period, with individual files capped at 35MB. For accounting firms managing 20+ clients during tax season, this creates an immediate bottleneck.
Real-World Impact
A bookkeeping firm with 30 clients averaging 40 bank statement pages each needs to process 1,200 pages monthly. With Hubdoc's 1,000 document daily cap, you'll hit the limit processing just 25 clients in a single batch upload session.
The 35MB file size restriction compounds the problem. Multi-account consolidated statements from enterprise clients frequently exceed this limit, forcing manual document splitting before upload. This pre-processing step adds 5-10 minutes per oversized statement.
Unlike true batch processing systems, Hubdoc's volume restrictions require careful planning around the 24-hour reset window, creating workflow disruptions during month-end close periods.
Processing Queue Delays During Tax Season
Hubdoc uses a queue-based processing system where documents wait in line for OCR extraction. During peak accounting periods (January-April tax season, December year-end close), users report processing delays extending 8-10 hours from upload to completion.
Upload batch of client statements
Documents still processing in queue
These delays cascade through accounting workflows. Teams waiting on processed data to begin reconciliation lose entire working days to queue bottlenecks. One CPA firm reported missing a client filing deadline because Hubdoc's processing queue delayed critical financial statement extraction by 12 hours.
The queue-based architecture means processing speed varies unpredictably based on system load. While low-volume off-season uploads might process in minutes, firms can't rely on consistent turnaround times when managing deadline-driven work.

Contact Volume Performance Degradation
Hubdoc's performance degrades significantly when connected to Xero organizations with large contact databases. According to Xero support documentation, Hubdoc becomes unusable with clients having 43,000+ contacts and shows noticeable slowdowns at just 1,000 contacts.
Performance Degradation Thresholds
This limitation disproportionately impacts accounting firms serving enterprise clients, ecommerce businesses with extensive customer databases, or property management companies tracking hundreds of tenants. Firms managing high-volume clients face a choice: accept degraded Hubdoc performance or exclude their largest clients from automated workflows.
The contact volume issue compounds during multi-account processing, where document matching across multiple bank accounts requires cross-referencing contact data repeatedly.
Why Accounting Firms Need True Batch Processing
True batch processing means uploading 50+ documents simultaneously and receiving processed results within minutes, regardless of system load or time of year. For accounting firms, this capability transforms monthly workflows from multi-day marathons into same-day operations.
Tax Season Scalability
Process 200+ client statements in parallel without queue delays
Predictable Turnaround
Consistent 5-10 minute processing regardless of volume
No Pre-Processing
Handle 100MB+ files and multi-account PDFs without splitting
Batch processing eliminates "per-page anxiety" - the constant mental calculation of whether processing another client's documents will trigger overage fees or hit volume caps. Firms using unlimited batch systems report 30-40% faster month-end close cycles simply by removing upload hesitation.
The efficiency gains compound at scale. Processing 50 clients with 5-document upload batches (250 total documents) requires 50 individual upload sessions with Hubdoc's daily cap. True batch processing handles this in a single 10-minute upload session. Explore automated reconciliation workflows that leverage batch processing.

Zera Books Unlimited Batch Processing
Zera Books processes bank statements, financial statements, invoices, and checks with zero upload caps, no file size restrictions, and no queue delays. The platform is built specifically for accounting firms managing high document volumes across multiple clients.
What's Included in Unlimited Batch Processing
Unlike Hubdoc's queue-based system, Zera Books uses parallel processing architecture that scales with upload volume. Processing 10 documents takes the same time as processing 100 documents - typically 5-10 minutes from upload to downloadable Excel/QBO files.
The platform includes AI-powered transaction categorization that auto-maps extracted data to QuickBooks and Xero chart of accounts, eliminating the manual categorization step that consumes 30-45 minutes per client with basic conversion tools.
