Today we will discuss which billing system is better for your requirement. In most forum you will notice that this question is being asked frequently.
Let us first talk about WHMCS. WHMCS was leading billing system in the past several years and the reason was, there was no other system which was providing all features at such low rate. Also, support system is built-in WHMCS. This reduces the cost of additional support system. WHMCS comes with lots of modules for control panels, registrars, payment gateways. There is no separate cost to get all this modules. That means, once you get license, you can use any modules available in WHMCS.
As of WHMCS 7.0, they announced about price change and their license structure. You can refer our recent post. They will be now charging based on number of active customers. This may cost more for those users who have more than 250+ active clients. This may affect WHMCS sales as well because many users may go for alternative license like Blesta.
Blesta is an alternative billing system. They are gaining market day by day. Most users prefer Blesta over WHMCS because you can see all code except 2-3 files. This is good for those who are looking for custom development. The main drawback may be modules. Currently limited control panel, registrar and payment gateway modules available for Blesta compare to WHMCS. But most of the users find them sufficient.
While comparing the price, Blesta cost less compare to WHMCS. If you purchase Blesta license from reseller like LicensePal, you can get license start from $9.95/month. You will get discount on monthly license while purchasing from such reseller.
