Why your "Free" API trial is a ticking time bomb
Most eSignature SaaS companies follow the same playbook. They lure you in with a limited free tier or a low-cost starter plan. Then, as soon as your startup starts to scale, they hit you with per-envelope fees that eat your margins.
The real cost of SaaS signing
- DocuSign: Charges upwards of 4.00 per document on many plans once you exceed a small limit.
- Dropbox Sign: Often requires an annual commit just to access basic API features.
- Vendor Lock-in: Your sensitive legal documents are stored on their servers, making it hard to leave.
DocuSeal replaces this model. It is an open-source, API-first platform. By hosting it on Opsily, you get the convenience of a managed service without the predatory pricing of enterprise SaaS.

We were paying per user on everything and it added up fast. Now we run five apps for less than one of those old plans. My finance team finally stopped asking questions.
