20 users. 200 WhatsApp sends. 50 selfie validations. On ZapSign, this scenario costs R$ 310 per month — just in extras, on top of the plan. On Signater: R$ 0.
ZapSign advertises accessible prices, but the list of additional charges transforms the real cost into something very different from what appears on the pricing page. Each essential feature — from WhatsApp sending to identity validation — comes with a separate price tag. This comparison puts the numbers side by side so the decision is based on data, not promises.
The Brazilian electronic signature market is experiencing accelerated expansion. Companies of all sizes are migrating analog processes to digital — and the right platform choice directly impacts cash flow. A per-unit pricing model may seem cheap at first but becomes unpredictable as volume grows. Predicting the monthly budget should be simple, not a guessing game.

Beware of "unlimited plans"
In recent months, hundreds of companies have migrated from platforms like ZapSign to Signater. The most frequent reason: frustration with promises that don't deliver. Plans marketed as "unlimited" often hide per-feature charges, confusing interfaces that slow down operations, and support that doesn't resolve issues. The result is that teams end up avoiding the very tool they're paying for.
With Signater, everything is truly included — SMS, email, selfie with liveness detection, unlimited users, and self-service API. No credits, no per-send charges, no billing surprises. The price you see is the price you pay.
