White-label software for agencies. Build client apps with AI and resell them

How agencies use AI to build custom software for clients and resell it under their own brand in 2026. CRMs, portals, agents. With recurring revenue instead of one-off projects.

Building a client app in AITIZER

Agencies have a math problem: projects end, payroll doesn't. The agencies growing fastest in 2026 have found a way out. They build custom software for clients with AI and charge a monthly fee to run it, under their own brand.

Why now

Two years ago a custom CRM for a client was a three-month project. Today you can describe it, build it in an afternoon and spend the rest of the week on the details that make the client happy. The cost of building collapsed; the value of a system that fits the client's process did not.

What agencies are selling

  • Industry CRMs. Real estate, clinics, schools, gyms, law firms.
  • Client portals. Status, files, invoices, approvals.
  • AI agents on WhatsApp. Lead qualification, bookings, support.
  • Internal tools. Approvals, stock, field service, quoting.
  • Dashboards. The numbers the owner checks every morning.

How white-label works on AITIZER

  1. Build each client's system in its own workspace. Isolated data, users and agents.
  2. Publish on the client's domain with your branding or theirs (Pro and above).
  3. On Business, white-label the platform itself: your logo, colors and domain for the admin area, so clients log in to your product.
  4. Charge monthly. You pay one plan; the client pays you for the outcome.

Pricing your offer

A simple model that works: a setup fee that covers discovery and the first build, plus a monthly fee that includes hosting, the AI agent, small changes and support. Price on value. Hours saved, leads captured. Not on the hours you spent.

Keep the client, keep the exit

Clients worry about lock-in. Show them the exit: their data exports as CSV at any time, and from the Pro plan every table has a full REST API and the app's code can be exported to GitHub. Counter-intuitively, an easy exit makes clients stay.

Build it on AITIZER. Free, no card
