If your team needs weeks to learn to navigate a digital signing platform, something isn't working. Electronic signatures exist to simplify processes — not create new ones. When basic features are hidden in confusing menus and access to essential resources depends on contacting the sales team, the promise of agility turns into yet another layer of bureaucracy.
Signater was designed with an absolute focus on user experience. Anyone on the team can create, send, and manage documents for signing in minutes — without training, without lengthy manuals, without frustrations. The search for a platform that truly works day to day, with autonomy and without surprises, is what motivates so many companies to migrate.
Electronic signature adoption in Brazil follows an accelerated curve. Market research indicates that 95% of companies already use or plan to adopt this technology in the coming years. In this scenario, choosing the right platform isn't an operational detail — it's a strategic decision that impacts productivity, costs, and end-client experience.

Intuitive interface from first access
While new D4Sign users spend weeks adapting to the system, anyone on Signater's team starts operating in minutes — the result of continuous investments in user experience.
The cost of a complex interface goes beyond the time lost in the initial learning curve. Each new team member needs training, each poorly placed feature generates support tickets, and each unnecessary click multiplies across hundreds of documents per month. Companies using platforms with poor usability report up to 3x more time spent on administrative tasks related to document signing.

All without scheduling meetings, waiting for approvals, or filling out forms.

Beware of "unlimited plans"
In recent months, hundreds of companies have migrated from platforms like D4Sign 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.
