What This Means for Your Firm
With Klippa, you get invoice data extraction—but you still need to manually categorize transactions, assign to clients, and format for your accounting software. With Zera Books, you upload an invoice and get a QuickBooks-ready file with AI-categorized line items in seconds.
Time saved per invoice: 30-45 minutes when you factor in categorization, client assignment, and export formatting. At 20 invoices per week, that's 10-15 hours recovered.
Pricing: Custom Volume-Based vs Unlimited Flat Rate
Klippa's pricing scales with document volume. Zera Books charges $79/month regardless of how many invoices you process.
Klippa Pricing
Based on volume and field count
- Contact sales for custom quote
- Pricing varies by document volume
- Additional costs for more fields extracted
- No published pricing tiers
- Potential overage fees at high volumes
"Pricing depends on the amount of fields and document volume to be processed."
Zera Books Pricing
Unlimited conversions, all features
- Unlimited invoice processing
- Process bank statements, financial statements, checks too
- AI transaction categorization included
- Client management dashboard included
- No overage fees, no per-page charges
Cost Predictability for Accounting Firms
Klippa's volume-based pricing makes sense for enterprises with predictable document flow. But for accounting firms, invoice volumes spike during tax season, month-end close, and audit prep. With Zera Books' flat $79/month, you never worry about usage tracking or surprise bills.
Example scenario: Processing 200 invoices in January, 800 in April (tax season). With Klippa, your costs fluctuate. With Zera Books, you pay the same $79 every month—and you can process bank statements and financial statements with the same subscription.
"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."
