Cash flow is the lifeblood of business, and invoicing is the heart that pumps it. Yet most businesses treat invoicing as an afterthought, manual processes that delay payment, introduce errors, and consume countless hours of administrative time.
The average B2B invoice takes 38 days to get paid. 60% of small businesses struggle with cash flow due to late payments. These aren't just statistics, they're constraints on your ability to grow, hire, invest, and survive unexpected challenges.
Invoice automation transforms this equation. By eliminating manual steps, ensuring consistent follow-up, and making payment effortless, you can dramatically accelerate cash flow while reducing the cost of getting paid.
The Cash Flow Crisis
Late payments are an existential threats to growing businesses.
The payment gap reality:
- Average B2B payment: 38 days past invoice date
- 60% of invoices are paid late
- Cash flow problems are the #1 reason small businesses fail
What this costs you:
- Delayed investments and missed opportunities
- Borrowing costs to bridge gaps
- Time chasing payments instead of serving customers
- Stress and uncertainty about financial position
The True Cost of Manual Invoicing
| Cost Category | Manual Process | Automated Process | Annual Savings (100 invoices/month) |
|---|---|---|---|
| Time per invoice | 15-30 min | 2-5 min | $15,000-25,000 |
| Error rate | 10-15% | <1% | $6,000-10,000 |
| Follow-up time | 10 min/invoice | 0 (automated) | $10,000-15,000 |
| Late payment interest | 8-12% of AR | Reduced 50%+ | $5,000-15,000 |
| Total Annual Cost | $36,000-65,000 |
For a business sending 100 invoices monthly, manual processes cost $36,000-65,000 annually, far exceeding the cost of automation.

|---|---|---|
| Average | 45 days | 32 days |
| Median | 38 days | 27 days |
| 90th percentile | 75 days | 50 days |
Working capital impact: For a business with $1M in annual receivables, reducing DSO from 45 to 32 days frees approximately $35,000 in working capital, permanently available for other uses.
Cash Flow: Get Paid 7-14 Days Faster
- Invoice sent 3 days faster (immediate generation)
- Payment made 4 days faster (online payment convenience)
- Follow-up saves 5 days (automated reminders)
