WhatsApp for solar panel installers

Customers send a screenshot of their inverter app. The installer who can explain it is up on a roof.

Short answerFor solar panel installers it works like this: customers keep the WhatsApp number they already know, and every message goes automatically to the installer. Photos, videos, voice notes and locations come along too. The installer replies in their own WhatsApp with the standard Reply function, and the customer receives the answer from the business number. No new number, no extra app, about 2 minutes to set up and the first 30 days free.

What it costs

You start with 30 days of Pro+ free, without payment details. After that you choose Pro at €87 per month (2,000 messages) or Pro+ at €142 per month (unlimited), or you stay on free Basic with 25 customer messages per month. You cancel with one click and your paid month simply runs to its end.

Honestly: what it does not do

InBetween sends each customer conversation to one recipient at a time, for example the installer or the planner; on Pro or Pro+ new customers are offered to all your coworkers. It does not split messages by topic, and it is not scheduling software or a CRM. It is also not an official Meta product: you link your number the same way as WhatsApp Web.

How it works, in 3 steps

  1. Create an account at app.in-between.tech with your email address and a password. No card needed.
  2. Connect WhatsApp: scan the QR code or enter the pairing code, exactly like WhatsApp Web. Your phone keeps working as normal.
  3. Enter your coworker's number. From then on every customer message reaches your coworker. When they reply, the answer goes back to the customer from your business number.

Photos, locations, voice notes and documents come along. With Pause you stop forwarding temporarily, for example in the evening. Messages wait until you switch it back on.

Forward customer messages automatically. Replies go back from your number.

Frequently asked questions

Can I separate service and sales?

Not automatically. Messages follow the customer, not the topic: each customer stays with one recipient, who passes them on if needed. That is deliberately kept simple.

Do I need a new WhatsApp number?

No. You connect your existing WhatsApp or WhatsApp Business number, the same way you would connect WhatsApp Web. Customers keep messaging the number they already know.

Can my coworker see customer phone numbers?

Not by default. Your coworker sees "Customer 1", "Customer 2" and so on. You can choose to show numbers in the dashboard.

How much does it cost?

New accounts get 30 days of Pro+ free without a card. After that you can stay on free Basic (25 customer messages per month), or choose Pro at €87 per month (2,000 messages) or Pro+ at €142 per month (unlimited). Cancel monthly.
