White-Label SaaS: What It Is and How to Build It

White-label SaaS lets other businesses buy your software and resell it under their own brand to their own customers. It's a powerful B2B2B revenue model where a single partner relationship can bring you dozens of end customers.

What White-Label SaaS Looks Like

A white-label SaaS removes your branding and replaces it with the partner's brand. Their customers see the partner's logo, colors, and domain — they don't know your product exists. The partner pays you a wholesale rate and charges their customers retail pricing.

Technical Requirements

Building white-label into your SaaS requires:

• Custom domains — each partner's app runs on their own domain (e.g., app.theircompany.com)
• Dynamic theming — logo, primary color, and fonts loaded per-domain from your database
• Email from-address customization — transactional emails sent from the partner's domain
• Subdomain isolation — data is segmented per partner, so partners can't see each other's customers

Custom Domain Architecture

Use a wildcard DNS record (*.yoursaas.com) and handle domain routing in your server middleware. For partner custom domains (their actual domain), use a platform that supports wildcard SSL certificates — Replit's custom domain feature supports this pattern.

Pricing White-Label Access

White-label licenses command significant premiums: $500–2,000/month for the white-label capability, plus a per-customer or per-seat fee on top. Partners expect to pay more because they're reselling at a markup — your product needs to give them enough margin to make the partnership worthwhile.

When to Add White-Label

Don't build white-label in your MVP. Add it when you have a partner who specifically requests it and is willing to pay for it. White-label is a feature worth building for the right partner relationship — not a speculative investment before you have demand.

Pricing Your White-Label Offering

White-label customers are not buying software — they are buying a business in a box. Price accordingly. A $99/month product used by an agency to serve 50 of their own clients should cost significantly more than $99/month in white-label form. Common structures include a flat agency fee ($299–999/month) plus per-seat charges for their end clients. Always require a minimum contract term for white-label agreements — monthly white-label churn is operationally expensive and the economics rarely justify it at lower price points.
