Recurring Contract Billing For WHMCS will open up the chance for you to offer products and services on the basis of fixed-term contracts. By virtue of the ability to precisely set the contract time frame, you will be no longer bound by the predefined billing cycles which you had to use until now.

The module will let you choose which of your products shall require clients to confirm a contract before ordering. In case you place such an order in the admin area, the customer will be emailed a link to easily view and accept the contract. You are also provided with the option to upload contracts directly from the admin area for chosen clients and services. A single contract can be formulated in various languages as well as assigned a discount value and penalty amount applicable in case of its breach. You will even be free to pick the way each contract should be signed - it can be done either through the checkbox tick, file upload or by means of the electronic signature. No less important is the opportunity to define a renewal type of every contract along with its trial period, that is days when a client may resign without any financial consequences. Customers will not face penalties also if they cancel the contract during the previously specified time period before its expiration. Additionally, you will be able to send ending contract notifications with renewal possibilities plus monitor key statistics and logs thanks to transparent tables located on the dashboard.

Recurring Contract Billing For WHMCS will decidedly widen the scope of pricing and billing functionalities in your system. Order the module today and take the best route towards greater business flexibility!

    Having trialled this module extensively before purchasing, it has proven to be a very useful module, making up for a shortfall in WHMCS’s default capabilities. The need to obtain signed contracts before provisioning services is vital for many hosting businesses, especially for our as we move into facilitating other services that require a minimum-term commitment. Currently, WHMCS does not support anyway of tying-in customers into a contractual period before provisioning services. With this module, we have been able to get signed contracts from our clients before services are automatically provisioned – allowing us to provide different levels of discount off their monthly charge, based on how long they have committed to in their contract. Cannot recommend this enough.
