I am looking for something that can provide a helpdesk, a decent api and excellent invoicing/billing/crm features, at either a more affordable price, or ideally an open source solution.
Can anyone recommend anything?
NOTE: It needs to run on a typical LAMP stack.
We use WHMCS because we are a webhosting company. It's perfect for that, but we also realised it can be used for other purposes. Specifically, we have started using parts of WHMCS for other businesses for these reasons: - Excellent Invoicing / Billing / CRM - Excellent Helpdesk - Decent API with an "Internal API" option. The problem is, WHMCS is most likely as expensive as it is because of the web host specific features it provides. And it's gotten even more expensive now that they limit it by number of clients.
