Below about thirty clients WHMCS is cheaper — a fact usually left out. Above that the gap runs the other way and widens. What the difference actually buys on each side.
Ilinca Bostan6 min readClientexec is the quietest name on most hosting billing shortlists and the cheapest published entry point with unlimited clients. WHMCS is the category default. Providers comparing them are usually asking one question: what am I giving up for the price difference?
Here is what both vendors publish, read on 18 August 2026.
How this was sourced. FluxBilling publishes this comparison and sells a competing product. Every WHMCS and Clientexec figure was read from the vendor's own pricing page on 18 August 2026 and both sources are linked at the end. Prices change, so check the source before you buy. Figures are in the currency each vendor publishes with no exchange rate applied.
Clientexec sells two leased plans, both unlimited: Branded at $1.00 for the first month then $16.95/month, and Unbranded at $1.00 for the first month then $19.95/month. Both include unlimited clients, products, servers, tickets and orders, lifetime updates, unlimited support, a 30-day free trial, and a complimentary $12 eNom domain reseller account.
WHMCS prices by active client count on two ladders. Self-hosted licences are $34.95/month for 250 clients, $54.95/month for 500 and $84.95/month for 1,000. Fully managed cloud plans are $9.99/month for 25 clients, $25.00/month for 100 and $75.00/month for 300, with additional clients at $0.40 each on Starter (up to 50) and $0.25 each on Growth and Expansion. Prices exclude tax; there is a 30-day money-back guarantee.
| Clients | WHMCS | Clientexec |
|---|---|---|
| 25 | $9.99/mo (cloud Starter) | $16.95/mo |
| 100 | $25.00/mo (cloud Growth) | $16.95/mo |
| 250 | $34.95/mo (Plus) | $16.95/mo |
| 500 | $54.95/mo (Professional) | $16.95/mo |
| 1,000 | $84.95/mo (Business) | $16.95/mo |
| Above 1,000 | Not published on the self-hosted ladder | $16.95/mo |
All figures USD as published on 18 August 2026, branded tiers where both exist.
This is the part usually left out of the comparison. WHMCS cloud Starter at $9.99/month undercuts Clientexec's $16.95 for a small provider, and includes a managed deployment that Clientexec's leased licences do not — you are not patching a billing server. For someone starting out with twenty customers, WHMCS is both cheaper and less work.
The crossover arrives fast. By 100 clients WHMCS cloud Growth is $25.00 against $16.95, and by 250 the self-hosted ladder is $34.95 against the same $16.95. From there the gap only widens, and at the top of the published WHMCS ladder it is roughly five to one.
The ecosystem, and it is not close. WHMCS documents around 25 server modules and roughly 70 payment gateway modules, and the third-party market around it is larger than everything else in this category combined. Registrars, control panel vendors and datacenter suppliers publish WHMCS modules as a matter of course. If you need a specific integration, WHMCS is the platform most likely to already have it, and that is worth real money if the integration you need is unusual.
A managed option. WHMCS's cloud ladder removes the job of running the billing server. Clientexec's published plans are licences you install and operate.
Migration tooling that reads from more sources. WHMCS's ImportAssist is free to licence holders and imports from Blesta, Clientexec, HostBill and other WHMCS installations. Clientexec ships a WHMCS importer covering clients, packages, invoices, tickets and servers, tested against WHMCS 8.x. Both directions are supported, but the inbound path to WHMCS is broader. Detail in which platforms ship an importer.
A flat bill. Growth stops being a line item. For a provider with a long tail of small accounts this is structural, not a discount — per-client pricing charges the same for a €3 customer and a €400 one.
A real trial. Thirty days free plus a $1 first month means you can evaluate on your own data before committing. WHMCS offers a 30-day money-back guarantee, which is a refund rather than a trial.
Support and updates folded in. Clientexec advertises unlimited support and lifetime updates within the lease, so there is no separate renewal to budget.
Neither publishes a built-in datacenter infrastructure layer — no rack elevations, no hardware inventory with out-of-band credentials, no IP address management with allocation on provisioning, no switch or PDU tracking. For a shared hosting or VPS-resale business that is irrelevant. If you rack machines, it is a second subscription plus an integration, and it usually costs more than the difference between these two. We priced that route in which platforms include DCIM, IPAM and colocation.
FluxBilling is a subscription platform: Lite €4.95/month (10 clients), Starter €24.95/month (250 clients), Professional €34.95/month (500 clients), Business €44.95/month (unlimited clients). White-label branding is a €50/month add-on on any tier. Self-hosting is Business-tier only, a €500 one-time fee on top of the subscription. No free trial; 14-day money-back guarantee.
Stating the obvious: on unlimited clients, Clientexec at $16.95 is well under our Business tier at €44.95, and it offers a 30-day trial where we offer a refund window. If your requirement is the cheapest unlimited-client platform with a way to try it first, this comparison has already answered you and the answer is Clientexec. WHMCS's ecosystem is likewise far larger than ours.
Our argument is only relevant if you own hardware: DCIM, IPAM, rack management, hardware inventory and bare-metal provisioning are in every tier including Lite, plus WHMCS and EasyDCIM importers on every tier. If you have no hardware, that is a feature you will not use.

Pick WHMCS if you are small enough that the cloud tier is cheaper, if you want someone else running the server, or if your business depends on a module that only exists in its ecosystem.
Pick Clientexec if you have or expect more than a couple of hundred accounts, want the bill to stop scaling with them, and want to evaluate on live data before paying.

If you want to own your billing platform rather than rent it, these are the two options — and beyond that they are almost nothing alike. One product versus four, and where each wins.
A thousand customers paying four euros is a different billing problem from forty paying four hundred. Per-client pricing, support load and involuntary churn decide this segment, not feature counts.
VPS billing looks simple until a customer resizes. Which platforms support your hypervisor, which edition it sits in, and the five flows that actually break.
