Quick Answer
Nanonets pricing ranges from $0 (free tier with severe limits) to $499+/month depending on document volume. For accounting firms processing 50+ statements monthly, costs typically land between $200–$500/month. Zera Books offers unlimited processing at a flat $79/month — no volume calculations needed.
1How Nanonets Structures Its Pricing
Nanonets uses a freemium model with volume-based tiers. The free tier is heavily limited — designed more for testing than production use. Paid plans range from approximately $0.30 per document on lower tiers to custom enterprise pricing for high-volume users. Nanonets also offers quotation-based pricing for organizations with specific requirements.
The challenge for accounting firms is that Nanonets doesn't clearly publish per-document costs for bank statement conversion specifically. Their pricing page focuses on general document processing — invoices, receipts, forms — making it difficult to compare costs for the specific use case accountants care about most.
2Calculating Your True Nanonets Cost
To estimate your Nanonets cost, you need to calculate total monthly documents. A mid-size firm with 25 clients typically processes 2–3 bank statements per client per month (checking, savings, credit card). That's 50–75 documents before factoring in multi-page statements or additional document types.
At Nanonets' reported $0.30 per document rate, 75 documents equals $22.50/month — but this assumes single-page documents. Multi-page bank statements often count as multiple documents. A 12-page annual statement could cost $3.60 alone. During tax season when firms process 6–12 months of back statements per client, costs can spike 3–4x in a single month.
Why Flat-Rate Pricing Matters for Accounting Firms:
- No monthly cost calculations — predictable budgeting every month
- Tax season volume spikes don't trigger surprise invoices
- No "should I process this?" decisions based on per-document cost
- Scale from 10 to 100+ clients without upgrading plans
3Step-by-Step: Calculate and Compare Your Costs
Count Your Monthly Documents
Tally all bank statements you process monthly. Include all accounts per client — checking, savings, credit cards. Don't forget multi-page statements count as multiple documents on volume-based plans.
Factor in Peak Season Volume
Tax season typically brings 3–4x normal volume. If you process 60 statements in October, plan for 180–240 in January. Volume-based pricing means your cost fluctuates dramatically — a significant challenge for firm budgeting.
Add Setup and Training Time
Nanonets requires model training for optimal accuracy. For bank statements, this means uploading training documents and iterating on extraction accuracy before production use. This initial investment isn't reflected in per-document pricing.
Compare to Flat-Rate Alternatives
Once you have your monthly volume, compare against flat-rate tools like Zera Books ($79/month unlimited). For firms processing 50+ documents monthly, the flat rate typically delivers better value and eliminates cost variability entirely.
Evaluate Feature Completeness
Price per document isn't everything. Check whether the tool includes AI categorization, client management, and direct accounting software integration — features that reduce downstream workflow time.

5Best Practices for Evaluating Document Processing Costs
Calculate total cost of ownership, not just per-document price. Include setup time, training data preparation, accuracy improvement iterations, and downstream manual work that results from lower extraction quality.
Model peak season costs separately. If your business is seasonal (tax preparation, year-end close), calculate your highest-volume month. Volume-based tools can become 3–4x more expensive during peak periods.
Factor in workflow automation value. A tool that includes AI categorization and direct QuickBooks integration saves 30–45 minutes per client. That time savings often exceeds the cost difference between tools.
Prefer specialized tools over general-purpose platforms. Nanonets is a general document processing tool. For bank statement conversion specifically, purpose-built bank statement converters typically deliver better accuracy and more relevant features.
6Summary: Volume Pricing vs Unlimited Processing
Nanonets is a powerful general-purpose document processing platform. For enterprises handling diverse document types at massive scale, their volume-based pricing can make sense. But for accounting firms focused primarily on bank statement conversion, the per-document model creates unnecessary cost complexity and budget unpredictability.
Zera Books eliminates this complexity with flat-rate unlimited processing, purpose-built for the accounting workflow. At $79/month with AI categorization, client management, and support for all four financial document types, it delivers more accounting-specific value at a predictable cost.
