Frequently asked questions
- Does StiffProof require an account, like Wave?
- No. Wave's Starter plan is free but still requires creating an account. StiffProof's generator works with no signup at all — an account is an optional convenience layer, not a requirement to use the tool.
- Is StiffProof free the way Wave Starter is free?
- Both have a genuinely free tier for creating documents. The difference is what happens after: StiffProof's free tier has no document caps and stays free forever; upgrading (flat $7/mo, no per-invoice metering) adds convenience, never previously-free features.
- What does Wave charge for payment processing?
- Wave's Starter plan charges 2.9% + $0.60 per card transaction (3.4% + $0.60 for Amex); its paid Pro plan ($19/mo) waives the flat fee on the first 10 transactions each month.
