ProperSoft vs Zera Books: AI Categorization Comparison
ProperSoft converts bank statements to Excel but stops there. No AI categorization means you spend 30-45 minutes per client manually categorizing transactions in QuickBooks. Zera Books AI auto-categorizes with 95%+ accuracy, cutting that time to 2-3 minutes. Here's the complete breakdown.

The ProperSoft Workflow: Where Time Goes
ProperSoft does one thing: converts bank statement PDFs to Excel or CSV files. After that, you're on your own for categorization. Here's what that actually looks like for an accounting firm processing 20 clients per month.
Convert with ProperSoft
Upload PDF bank statement, get Excel file with raw transaction data.
Time: 2-3 minutes
Import to QuickBooks
Open QuickBooks, import CSV, map columns, verify dates and amounts.
Time: 5-7 minutes
Manually Categorize
Go through 150+ transactions one by one, assign categories, fix vendor names.
Time: 25-35 minutes
Total time per client: 32-45 minutes
For a firm with 20 clients per month, that's 10-15 hours of manual categorization work. Every single month.

Real ROI: ProperSoft vs Zera Books for Growing Firms
Let's compare actual costs for a bookkeeping firm processing 20 clients per month. We'll calculate both software costs and the value of time spent categorizing transactions.
| Metric | ProperSoft | Zera Books |
|---|---|---|
| Software Cost (Annual) | $49/year | $948/year ($79/month) |
| Time per client (including categorization) | 32-45 minutes | 2-3 minutes |
| Monthly time (20 clients) | 10-15 hours | 40-60 minutes |
| Annual time spent | 120-180 hours | 8-12 hours |

| Total Annual Cost | $6,049-$9,049 | $1,348-$1,548 |
ProperSoft Total Cost
$6,049-$9,049/year
Software is cheap, but manual categorization eats 120-180 hours annually
- 30-45 min manual work per client
- No scalability as you add clients
- Bottleneck during month-end close
Zera Books Total Cost
$1,348-$1,548/year
Higher software cost, but AI saves 112-168 hours of manual categorization
- 2-3 min AI-powered workflow per client

Annual Savings: $4,500-$7,500
Zera Books saves a 20-client firm between $4,500-$7,500 per year compared to ProperSoft when accounting for the value of time spent manually categorizing transactions. As you add more clients, the gap widens further.
"But What About AI Accuracy?"
The most common objection to AI categorization is accuracy concerns. Here's the reality: Zera AI at 95%+ accuracy is more reliable than manual categorization, and you still review everything before import.
Manual Categorization Reality
After 30 minutes of categorizing 150+ transactions, accuracy drops significantly:
- Attention fatigue leads to categorization errors
- Inconsistent rules across similar transactions
- Different categorizers use different logic
- No feedback loop to improve over time
Zera AI Categorization
AI doesn't get tired, maintains consistency, and improves with every correction:
- 95%+ accuracy validated by CPA professionals
- Consistent categorization rules across all transactions
- Learns from your corrections to improve accuracy
- You still review before importing to QuickBooks
The Real Accuracy Comparison
When you factor in human error from fatigue, inconsistency, and lack of domain knowledge, Zera AI's 95%+ accuracy typically matches or exceeds manual categorization accuracy—while completing the work in 5% of the time.

When ProperSoft Makes Sense (Rare Cases)
ProperSoft works for a very specific scenario: you only process 1-2 bank statements per month, and you already have a fast categorization workflow in your accounting software. But even then, the time savings from AI categorization usually justify the higher cost.
ProperSoft Edge Cases
Single personal statement monthly
If you only process your own bank statement once a month, the $49/year cost is reasonable
Already fast at manual categorization
If you can categorize transactions in 10 minutes, AI savings are minimal
No plans to scale
If you're not adding clients, you won't see compounding time savings
Zera Books for Everyone Else
Processing 5+ clients monthly
AI categorization saves hours with each additional client
Bookkeeping firms
Client management dashboard + AI categorization essential for scale
Month-end close bottlenecks
Eliminate the categorization delay when processing 20+ statements at once
The Verdict: AI Categorization Changes Everything
ProperSoft converts PDFs to Excel. That's it. Zera Books converts PDFs, auto-categorizes with AI, manages clients, and integrates directly with your accounting software. The price difference is negligible when you factor in the value of time saved.
Choose ProperSoft if:
- You process 1-2 personal statements monthly
- You're extremely fast at manual categorization
- Budget is the only consideration
Choose Zera Books if:
- You process 5+ clients monthly
- You want to eliminate manual categorization
- You value time more than $79/month
