  • Compatible with WooCommerce or Gravity Forms where relevant
  • Ready-to-install plugin files supplied with basic usage notes
  • 1 revision included

Built around your requirements

When an off-the-shelf plugin cannot do what your business needs, this service focuses on building something tailored from scratch. Rather than adapting a generic tool, the plugin or addon is coded to match your specific logic, keeping the codebase lean and avoiding awkward workarounds. The result is designed to sit comfortably within your existing WordPress setup, whether that is a single install or a more layered environment with several plugins working together.

What can be built

Work ranges from standalone custom plugins to addons for widely used tools such as WooCommerce and Gravity Forms. On the WooCommerce side, that might mean new payment gateways, tailored shipping options, distinct product types or bespoke admin utilities. For Gravity Forms, typical additions include extra conditional logic, new field types or webhook triggers. Third-party API work forms a central part of the offering too, covering shipping providers, print-on-demand services, Slack and Google tools such as Maps, Sheets and Calendar. If your project calls for a connection or extension not covered here, a quick message before ordering will confirm whether it can be accommodated. Development is supported by AI-assisted tools that speed up routine coding and review tasks, while the overall logic and quality checks remain hands-on.

How the process works

You start by outlining what the plugin should do, which API is involved and any plugins it needs to work alongside. Scope and feasibility are confirmed before development begins, so expectations are aligned from the outset. Once built and tested in a separate development environment, the finished plugin is handed over through the order manager together with plain-language usage notes so you can install it without difficulty.

Who this suits

This is intended for businesses that need functionality beyond what standard plugins offer and want code built specifically for their workflow. After delivery, you can request adjustments within the agreed revision allowance, and communication takes place in English on working days. If you are not certain your idea fits the scope, reaching out beforehand is welcome so guidance can be given ahead of ordering.

What happens after you buy

Your order opens its own thread here the moment it is paid, and everything about that order - questions, changes and the final report - happens in it.

Questions people ask

What information do I need to provide before you start?

Provide a clear outline of the plugin's purpose, the third-party API or APIs involved, any credentials or documentation links, and details of related plugins such as your WooCommerce or Gravity Forms version. More detail upfront means a faster start.

Does this package cover more than one API integration?

The package covers one third-party API integration. For projects needing several API connections, get in touch before ordering so the scope and price can be assessed properly.

Will the plugin work with my existing theme and other plugins?

Plugins are written to recognised WordPress coding standards to reduce conflicts, though compatibility across every theme and plugin combination cannot be promised without knowing your setup in advance. Share your environment details when ordering.

Do you provide the plugin code or install it for me?

Finished plugin files are delivered through the order manager as a zip file, which you upload via your WordPress admin area. If installation support is needed, this can be discussed separately.

What counts as a revision?

A revision covers fixes or small tweaks within the original agreed scope, such as correcting a bug. Requests that change the original brief or add new functionality would be treated as separate work.

Can you build addons for plugins other than WooCommerce and Gravity Forms?

Yes, addons can be developed for other established WordPress plugins beyond WooCommerce and Gravity Forms. Share your specific requirements to discuss what is possible.

Do you sign NDAs or keep project details confidential?

Project details are handled with discretion. If a formal non-disclosure agreement is required, raise this before ordering so terms can be agreed in advance.

How do AI tools assist your development process?

AI tools help speed up tasks like generating boilerplate code and supporting initial reviews, while architecture decisions and final quality checks remain carried out manually to keep delivery to a professional standard.
