What to look at while you test

Most tests are done the wrong way: the person writes nicely, the bot replies nicely, and the real customer breaks everything in the first week.

01

Build with your business, not with an example

Use your services, your prices and your rules. That is where you see whether the tool has somewhere to keep them or only repeats default text.

02

Write like your worst customer

Half a sentence, two questions together, a typo, audio and a question nobody anticipated. That is the test that matters.

03

See what is left afterward

When the conversation ends, check whether it became a contact, a deal and a task somewhere, or stayed only in the WhatsApp history.

04

Ask for the full-account price

Monthly fee, charges per conversation, per person and per connected number, plus what Meta charges separately. That is where the bill grows later.

How to run the test in one afternoon

Without installing anything and without changing the number your customers already use.

  1. Teach the business in a conversation

    The same way you would explain it to a new employee: what you sell, what it costs, what time you open and what must never be promised.

  2. Connect WhatsApp by scanning a code

    The agent starts answering on your number. You don't install an app, don't design a flow and don't need technical people.

  3. Talk to it as a customer

    Send messy text, audio and a hard question. Then open the dashboard and see what was recorded from the conversation.

What each type of test makes clear

Five questions that separate the tool that holds up from the one that only demos well.

A free trial is not the same as a free plan forever

Worth separating the two before deciding. Testing before paying is for seeing the tool work with your business. Running free forever doesn't exist anywhere serious: conversations cost model usage and infrastructure, and whoever promises unlimited free charges somewhere else.

There is no lock-in and no standard setup fee.

Frequently asked questions

Can I test before paying?
Do paid plans have a trial?

No. The paid plan is charged right away.

Do I need to change my number to test?

No. The agent answers on the number your customers already know, and you take over the conversation from the dashboard whenever you want.

Does the annual plan have a trial?
What do I lose if I cancel later?

There is no lock-in and no penalty. The number is yours: the plan provides the connection slot, not the number.

How much does a paid plan cost?

From US$ 75 per month on the Start plan. The full lineup, with what changes at each step, is at certu.com.br/planos.
