Frequently asked questions
- Does Invoice Simple have a free plan?
- It has a 14-day free trial of its Premium features, after which the cheapest plan is Essentials at $6.99/mo — and that plan is capped at 3 invoices a month. Invoice Simple does also run a free web invoice generator that opens straight into an editor without a signup form, which is worth knowing before you compare subscription prices. StiffProof takes the second approach and stops there: the generator is the free tier, it is unlimited, and it stays that way.

- How many invoices can I send on Invoice Simple?
- It depends which plan you are on: Essentials ($6.99/mo) allows up to 3 invoices a month, Plus ($14.99/mo) up to 10, and Premium ($21.99/mo) is unlimited. The invoice count is the tier boundary — paying more is how you raise it. StiffProof never meters documents in any tier, which is one of the four promises in our honesty pledge.

- Is Invoice Simple's payment processing cheaper than StiffProof's?
- It depends how you get paid. On US cards Invoice Simple lists "up to 3.49% + 49¢" against our flat 3.4% + 30¢, and on US bank transfers 1% + 30¢ capped at $15 against our 1% capped at $10 — so we are cheaper on both. But Invoice Simple's in-person Tap to Pay is 2.79% + 49¢, which beats our card rate for anyone taking payment on site, and we have no in-person equivalent.
