Most of the surprise in an e-signature invoice comes from a few mechanics rather than from the headline price. They are worth understanding before you compare any two quotes, including ours.
The account is the unit, the invite is the cap.
Business, Business Premium and Enterprise are priced per account, not per user, and users are unlimited. Shown to a visitor from Austria, that is €8, €15 and €30 per month billed annually, or €20, €30 and €50 billed monthly. Every annual plan includes 100 signature invites per account per year, and monthly plans 10 per month. Above that the plan switches to pay-as-you-go rather than stopping you.
Enterprise is the realistic tier for a growing team.
Approval steps and conditional fields are Enterprise features. Payment collection, online notarisation and EU data residency start at Business Premium, and the entry Business plan has none of them. Compare the tier you would actually run, not the lowest price on the page.
Full API access comes with the sales-led Site License, priced per signature invite from $1.50 with volume discounts. AES and QES are only available there, QES as a paid extra through trust service partners, and so are the native Salesforce, Microsoft Dynamics 365 and HubSpot integrations. Separate API plans start at $146 per month billed annually for 1,000 invites a year.
Contract management is a different product.
SignNow stores signed documents without limit, with folders and search, but it has no metadata extraction, renewal reminders or AI review. airSlate sells contract lifecycle features as a separate product, so if your evaluation started because signed contracts were getting lost, that is the second line item to price in.
What to ask for in writing.
Ask any vendor on your shortlist for the same three numbers: the total annual cost at your real document volume, what happens when you exceed the allowance, and what the second and third year look like after any first-year discount. Those three answers reorder most shortlists more than any feature table does.
