Custom WHMCS modules

We help implement an agreed billing workflow with admin controls and verified results.

How the service works and what is included

We lock in the scope, boundaries, and verifiable deliverables before starting.

For billing system owners

Your WHMCS setup needs a specific action, extra feature, or external system link. It is essential to define what triggers the scenario and what should happen to the service, order, or document. Billing customization requires strict boundaries and thorough testing.

A module tailored to your task

You receive a module built for your agreed billing workflow along with manageable admin settings. Delivery packaging and documentation are defined in the specification.

What we lock in the requirements

Before estimating, we inspect the environment and required actions. Billing scenario: we define the trigger event, rules, expected outcome, and exception handling, specifying financial operations with extra clarity. Admin panel and access: we align on administrator settings and required permissions, keeping secrets out of general task descriptions. Versions and integrations: we document the WHMCS version, related add-ons, and external interfaces, verifying that the required interaction is supported.

Compatibility and support

In the specification, we record the WHMCS version and third-party add-ons tested with the module. Support, updates, and future modifications are agreed upon before ordering. Other billing platforms require a separate evaluation.

Workflow and preparation

Execution stages and what is needed to get started.

Development process

We analyze the task and check existing modules and WHMCS capabilities. We agree on requirements, settings, and acceptance criteria. After development, we test normal operations and error cases using safe sample data. We hand over the deliverable, while installation and changes on the live billing system are arranged separately.

Information needed for an estimate

We need your WHMCS version, a list of affected add-ons, and a description of the workflow. Send an anonymized sample of the expected output and a list of exceptions. Specify any external systems involved and who is responsible for sign-off; live credentials will be requested separately via a secure channel.

Pricing and support

Cost and timeline are determined by the agreed specification and testing scope. Before ordering, we discuss handover, support, and update terms. Custom development and our own off-the-shelf modules follow different terms; for existing solutions, we confirm availability and scope separately.

Frequently asked questions

Can payment handling be customized?

Such a task must be described and verified against the selected payment services and WHMCS capabilities. We do not confirm scope without an assessment.

Do you need access to our live billing system?

Access requirements depend on the task. Testing is performed on agreed safe sample data or a staging environment.

Will the module be manageable from the admin panel?

Yes, agreed administrator settings are part of the requirements. The system owner should clearly see where to adjust relevant parameters.

What if we use a different billing platform?

This page covers WHMCS. We can evaluate another platform under a separate brief, without promising compatibility in advance.
