Custom WordPress Plugins, WHMCS Modules, and Integrations

If your website or billing system lacks a feature, we first check whether an existing solution fits the job. If not, we align on the requirements and build a custom plugin, module, or integration with admin settings you can adjust without touching code.

Choose your platform and task

WordPress Plugins

Website and WooCommerce features managed directly from the WordPress dashboard.

WHMCS Modules

What to include in your inquiry

Name the platform, current version, and required user or system action. Explain what happens now and what the outcome should be. For data transfer, specify the source and destination systems, the trigger event, and the field list. You can illustrate with sample data.

From requirements to testing

Ongoing support and future updates are arranged separately.

Step 01

We check whether an off-the-shelf module already solves the problem.

Step 02

We verify system compatibility and limitations, then agree on scope and pricing.

Step 03

We build the solution, test the defined scenarios, and hand it over as agreed.

How much does plugin development cost?

Pricing depends on the features, third-party APIs and limitations, source data quality, and testing requirements. Before quoting a price or turnaround in business days, we need to clarify this scope. Once agreed, you receive a priced proposal, and we arrange access handover as the next step. Pricing page

Frequently Asked Questions

Do I always need to order a custom plugin right away?

Not always. First we look for a suitable existing solution. Custom development is only needed when off-the-shelf features or controls do not cover the agreed task.

Will settings be accessible without editing code?

For WordPress plugins, dashboard manageability is a standard deliverable. We define the exact settings in the requirements.

Can any CRM be connected to the website?

That depends on the API, access permissions, and limitations of the specific systems. Tell us which systems you use and the desired workflow, and we will verify compatibility before sending a proposal.

Do you support the module after handover?

Support terms, compatible versions, and future updates are specified in the proposal. They are not automatically bundled into initial development.

Missing a feature?

Describe what needs to happen and in which system, and we will first check if a ready-made solution exists.
