Platforms

Five platforms. One partnership.

Five products your customers already shop for, each built on a CommStack platform you can sell as your own. Resell one or bundle them all. They share the same numbers, the same partner hub and the same API, so adding a second platform is a conversation, not a new supplier.

How it works

From hello to your first customer.

One line, five stops. We work alongside your team from the first call to go-live, then get out of the way so you can sell.

Start the conversation →

  1. 01Apply Tell us who you are

    Tell us about your business, your customers and the platforms you're interested in. We only work with partners, never direct.

  2. 02Agree Under NDA

    Sign a mutual NDA and receive the partner pack: wholesale pricing, feature matrices and coverage. Then the partner agreement and service schedules for what you'll sell.

  3. 03Brand Make it yours

    Point your domains at us. Studio sets up the certificates and shows you the DNS records to add, and you choose colours, fonts and the sign-in page your customers see.

    portal.yourbrand.comyour coloursyour sign-in

  4. 04Onboard With our team

    Discovery, kickoff, training and go-live sessions with our team, so you're confident selling and supporting from day one.

  5. 05Sell And bill your way

    Provision from the Hub (or the Partner API, on request), drop customers into their dashboard with single sign-on (Early access), and bill from real usage data.

Partner tools

Run it from our Hub, or from your own platform.

Everything you sell is managed in one place. Prefer to automate? Provisioning, numbers, porting, sign-in links and usage are in the Partner API, on request.

  • Partner HubYour command centre: services, numbers, porting, support and billing data, behind two-factor sign-in.
  • Partner API (Early access)Provision every platform, mint sign-in links and pull usage into your own systems. Every change can be dry-run first and safely retried.
  • StudioWhite-label every customer portal, on request: domain, colours, fonts and a choice of sign-in templates.
  • Single sign-on (Early access)One-time links, made through the Partner API, take customers from your portal straight into their phone system, SMS or AI Agents dashboard.

The detail lives in the partner pack.
