Pricing

Flat, or a ladder you climb forever.

Every Blesta license includes unlimited clients — the price never changes because your business grew. WHMCS prices by client count, in eleven tiers, so success literally raises your bill.

At the top of that ladder the difference stops being subtle: WHMCS's unlimited tier runs $1,999.95/mo. Blesta starts at $17.95/mo — about 1% of the price — and you can skip subscriptions entirely with a one-time owned license.

Source access

Read it. Audit it. Extend it.

Blesta ships as readable PHP — all but six files (three for licensing, three for Blesta AI). Debug in production, audit the security yourself, and customize anything without waiting on a vendor. It's a commercial license, not open source — but the code is yours to see.

WHMCS encodes its core with ionCube. You can't read what runs your billing, can't independently audit it, and customization stops where the hooks and templates end.

Security & transparency

Billing software keeps secrets. Vendors shouldn't.

Your billing system holds customer data and payment flows — how a vendor handles vulnerabilities matters as much as how it prevents them.

Public security advisories for every vulnerability
Patches shipped before known exploitation
Readable source — audit it independently
TOTP two-factor, anti-fraud checks, responsible disclosure program

WHMCS

Vulnerabilities often patched without public advisories
Theme compromises in its ecosystem in 2023–2024 (HostX, ClientX, CloudX)
Encoded core prevents independent auditing
Two-factor authentication available

Multi-company

Every brand. One login.

Run multiple hosting brands? Blesta's multi-company support is native: one installation, one staff login, each company with its own domain, branding, settings, and clients. Additional companies are a simple add-on — $5/mo or $95 one-time each.

WHMCS has no native equivalent. You either buy third-party modules or run — and license — a separate installation per brand.

FAQ

The questions everyone asks.

Which is cheaper — Blesta or WHMCS?

Blesta, at every size. It starts at $17.95/mo with unlimited clients; WHMCS starts at $34.95/mo capped at 250 clients, and reaches $1,999.95/mo for unlimited. Blesta also offers owned licenses ($350–$500 one-time) that end recurring fees entirely — WHMCS is subscription-only.

Can I migrate from WHMCS to Blesta?

Yes. The Import Manager is built into every Blesta install and migrates clients, contacts, services, packages, invoices, transactions, and support tickets from WHMCS at no extra cost. Run it during your free trial and verify everything before you buy.

Can I really read and modify Blesta's code?

All but six files ship as readable PHP — three are encoded for licensing and three for Blesta AI. You can audit, debug, and extend everything else. Blesta is commercially licensed, not open source, but the code is open to you as a customer. WHMCS encodes its core with ionCube, so its internals are off-limits.

Which is more transparent about security?

Blesta publishes a public advisory for every vulnerability and ships patches quickly. WHMCS has historically patched issues without advisories, and its encoded core can't be independently audited. Blesta also runs a responsible disclosure program for researchers.

Does Blesta support multiple companies or brands?

Yes — natively. One installation and one staff login run all your brands, each with its own domain, branding, settings, and clients. Additional companies are $5/mo or $95 one-time each. WHMCS requires third-party modules or fully separate licensed installations.

What about integrations — doesn't WHMCS have more?

WHMCS's third-party marketplace is larger. Blesta ships 78 first-party integrations — 40+ provisioning modules, 30+ payment gateways, 12 registrars — built and maintained by us, with the Marketplace covering the long tail. If something's missing, the readable codebase makes custom modules straightforward, and it's possible to sponsor development of popular requests.
