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.
Unlimited requests, capped templates.
Every paid web plan includes unlimited signature requests, and only senders pay: someone who just receives and signs a request is not a sender. What is capped is the number of templates, at 5 on Essentials, 15 on Standard and unlimited on Premium. The free plan allows three signature requests a month for one user, and paid plans come with a 30-day trial.
Standard is the realistic team plan.
Essentials is a single-user plan at US$15 per month, billed annually. Standard is the plan for small teams, at US$25 per user per month billed annually and starting at US$600 a year for two users. It adds in-person signing, advanced signer fields and the HubSpot integration. For five or more users, Dropbox asks you to contact sales.
The team features are quoted.
EU data residency, SSO, SMS authentication, multi-team administration and the Salesforce integration sit in Premium, which is for five or more users and is sold through a custom quote. Salesforce is additionally listed as an add-on at extra cost. If any of those is a must-have, the Standard price is not the number to compare.
Advanced and qualified signatures are an API purchase.
The API is a separate product with its own plans: API Essentials at US$75 per month for 50 signature requests, API Standard at US$250 per month for 100, and API Premium on request. Dropbox Sign eID, which provides AES and QES through providers such as Swisscom, Belgian eID or itsme, is an add-on on API Premium. If your contracts need a qualified signature, that is the line item to ask about.
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.
