When to Use Each

Choose Instant Invoice:

  • ✓ You invoice from contracts + receipts
  • ✓ Speed is critical (10 sec vs 15 min)
  • ✓ You hate manual data entry
  • ✓ You attach reimbursement receipts

  • ✓ You invoice 2-5 times per month

Choose Wave:

  • ✓ You need unlimited invoices
  • ✓ You want payment processing
  • ✓ You need accounting reports

Our Recommendation

If you invoice 1-10 clients per month and value your time highly: Instant Invoice saves you hours with AI automation. The free tier (5/month) covers you.

If you invoice 20+ clients or need accounting features: Wave is better. Unlimited invoices, payment processing, full accounting. The manual data entry trade-off is worth it for high-volume invoicing.
