FAQ

Before you get started.

Is Outbound OS free?

Yes. The complete software is open source under AGPL-3.0. You can install it yourself without a software subscription. Hosting, WhatsApp messaging and other providers can have their own costs.

What can you set up for my business?

We offer installation, a direct Meta WhatsApp connection, email and lead-source setup, contact imports and a team walkthrough. Managed hosting and ongoing assistance are also available. We agree the scope and quote before work starts.

Can I keep my existing WhatsApp number?

We first check your current number and Meta Business account. A number already connected through another provider may need a migration. We plan that with you before making changes.

Does this include the WhatsApp messaging fees?

Software and setup services are separate from Meta messaging charges and other provider costs. Your proposal will explain which infrastructure costs are included and which are billed separately.

Can I move to self-hosting later?

Yes. Managed setup uses the same open-source product. You can export your data and run your own instance. We can include a handover in your service scope.
