WHMCS advertises plans starting from $15.95 per month. That sounds reasonable until you start adding up everything else you need.
The WHMCS Licence
The Starter plan caps you at 250 active clients. When you cross that threshold, you move to Growth at $25.95 per month and then Business at $49.95 per month. Annualised: $191 to $599 per year just for the licence.
The Server WHMCS Runs On
WHMCS requires its own hosting environment separate from your website. Minimum viable: a basic VPS at $10-20 per month. Recommended: a managed VPS at $30-60 per month. Annualised: $120 to $720 per year.
The Template and Add-Ons
WHMCS ships with a default template that looks like every other WHMCS installation. A premium template costs $50-150. Common paid add-ons include domain registrar integrations, fraud detection and custom payment gateways, adding $200-500 per year.
The Real Annual Cost
A mid-sized operation on WHMCS Growth plan with a VPS server, premium template and basic add-ons costs approximately $931 per year. Compare this to MHM Theme: a one-time purchase running on your existing WordPress installation with no monthly licence and no add-on ecosystem required for basic operation.
