SaaS vs Redistribution Rights – Explained

Two powerful ways to resell software. Choose what fits your business.

What is SaaS?

You host. Clients sign up.

You host the software on your server. Clients create accounts, use it, and pay you monthly. As admin, you control every client from one dashboard.

  • Recurring revenue — they stay on your product and pay every month.
  • One installation, many clients (multi-tenant). You do not ship a new installer for each sale.
  • Client registration by tier: Freelancer max 30, Startup max 80, Company unrestricted.
  • Multi-tenancy type: Freelancer and Startup share one database. Company gets a separate database per client.
What are Redistribution Rights?

You install per client.

This version has a multi-installation facility. You install the software separately for each client. The license in the software controls piracy or misuse.

  • One-time fee per client — or your own price — under your white-label brand.
  • Unlimited installation within your tier: Freelancer max 30 clients, Startup max 80, Company unrestricted.
  • Each client is a separate install (single-tenant), with full source code and lifetime updates.
  • License Management System on the Company tier locks installs (domain locking) so leaked copies cannot run.
Key Difference

How you deliver — and how you get paid.

SaaS: You host it on your server. Clients sign up and pay monthly. One installation serves all clients (multi-tenant).

Redistribution Rights: Multi-installation facility. You install the software separately for each client (single-tenant). A license key in the software controls piracy or misuse.

  • SaaS caps who can register on your hosted product. Redistribution caps how many times you may install.
  • SaaS Company isolates data with a separate database per client. Redistribution Company isolates copies with a License Management System.
  • Same partnership prices either way: Freelancer $399, Startup $649, Company $999.

Both models include full source code, white label branding, lifetime updates, and support.

Your brand, your customers, no royalties, no recurring fees.
