eSignature API Pricing: What You Actually Pay — GoodSign vs. DocuSign vs. Adobe Sign
The Number That Changes the Calculation
Most eSignature pricing pages are designed to obscure cost, not communicate it. "Contact sales" buttons, feature tiers, per-seat minimums, overage clauses — by the time you've mapped your actual usage against a vendor's pricing grid, you've already lost an hour. Here's the short version: subscription-based APIs charge you whether you send or not. Pay-per-use eSignature APIs charge you only when you do.
GoodSign is built on the second model: $1.50 per envelope, no monthly fee, no user limits, API included from day one. The rest of this page breaks down exactly what that means at different sending volumes, shows you what the API actually looks like to integrate, and explains how the credit system works under the hood.
Direct Cost Comparison: GoodSign vs. DocuSign vs. Adobe Sign
The table below uses realistic volumes — freelancers, agencies, and growing SaaS teams integrating eSignature into their products. DocuSign and Adobe Sign both require plan upgrades or add-ons before you can automate a single send. GoodSign's API is included from day one.
| Scenario | GoodSign | DocuSign Standard | Adobe Sign |
|---|---|---|---|
| 50 envelopes/month, 1 user | $75/month | ~$25/month (capped at 100) | ~$20/month (annual) |
| 200 envelopes/month, 5 users | $300/month | ~$125/month + overages | ~$120/month + overages |
| 500 envelopes/month, 10 users | $750/month | ~$250/month + significant overages | ~$240/month + overages |
| Quiet month — 0 envelopes | $0 | $25–$250/month | $20–$240/month |
| API access | Included, all plans | Paid add-on or higher tier | Higher tiers only |
| Webhook support | All plans | Paid tiers only | Enterprise only |
| User limits | None | Per seat | Per seat |
The quiet month row is the one most teams underweight. Agencies lose clients. Freelancers take breaks. SaaS products have seasonal lulls. Subscription pricing bills you regardless. At 10 users, DocuSign charges ~$250/month during a month you sent nothing. GoodSign charges zero.
The overage dynamic cuts the other way too. DocuSign's standard plan caps envelopes per user — exceed that cap and you're paying overage rates on top of the subscription. GoodSign has no cap. Every envelope costs $1.50, whether it's your first or your five hundredth that month.
A Real Cost Calculator Example
Take a mid-size agency sending roughly 300 envelopes per month across a team of eight. Here's what the annual bill looks like side by side.
GoodSign: 300 × $1.50 × 12 = $5,400/year. Zero seat fees. API included. Slow months cost proportionally less — if August drops to 80 envelopes, August costs $120.
DocuSign Business Pro (8 seats): Approximately $400–$500/month at list pricing before overages, plus API access fees depending on tier. Annual total: $4,800–$6,000+ before overages kick in. A single high-volume month can push that figure significantly higher.
Adobe Sign (8 seats): Similar per-seat structure, approximately $350–$450/month on an annual commitment. Overages apply beyond the plan's envelope allocation. Annual total: $4,200–$5,400+, again before overages.
The honest read: at moderate, consistent volume, subscription tools can appear competitive. The moment your volume fluctuates — up or down — GoodSign's model becomes materially cheaper and far more predictable. There's no penalty for growth and no waste during slow periods.
What the GoodSign REST API Actually Looks Like
Pricing is only half the evaluation. The other half is whether the API is straightforward enough to ship without a week of reading documentation.
