Recurring Contract Billing For WHMCS will give you the flexibility to offer your products and services through fixed-term contracts. Empowered to choose how long each contract lasts, you are no loner stuck with the predefined billing cycles, and can customize your setup to suit your specific invoicing needs.

This module makes it easy to control which products require clients to confirm a contract before placing an order. When you initiate an order in the admin area, the customer will be emailed a link to conveniently view and accept the conditions. You also have the option to upload contracts directly from the admin area for specific clients and services. Contracts can be created in multiple languages and can include a discount value as well as penalty amount for any breaches. Additionally, you can choose how they are signed - whether through a checkbox, file upload, or electronic signature.

You will be able to define the renewal type for each contract and manage additional settings, affording customers the ability to end it without facing any financial consequences - either during a trial period or within a specific timeframe before the contract expires. To ensure everyone stays informed, the module enables you to send notifications to your clients regarding their expiring contracts and renewal options. Along with this, it allows you to track essential statistics and logs through clear and accessible tables located right on the dashboard.

Ditch the ordinary! Invest in Recurring Contract Billing For WHMCS today and let it propel your business toward newfound levels of pricing and billing freedom.

    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.
