How we work
Our plugin & extension development process
Seven stages, each with a visible output you can review and approve before the next one begins. No black box between kickoff and launch.
- 01
Discovery
We map the platform, the gap in functionality and the best extension point to build from.
- 02
Strategy
Architecture, API approach, marketplace requirements and timeline agreed in writing before build.
- 03
Design
UI reviewed and approved before development starts, including admin screens and settings pages.
- 04
Build
Clean, documented code built to platform coding standards, with demos at every milestone.
- 05
QA & Testing
Cross-version, cross-browser and edge-case testing before submission or deployment.
- 06
Launch
Marketplace submission handled or private deployment to your environment.
- 07
Support
Ongoing updates to stay compatible as platforms release new versions.
Why choose us
A plugin team that thinks about the platform
A plugin that works on your site today can break the day a platform releases a major update. Every decision we make is measured against long-term compatibility and review standards, not just getting something to work right now.
Talk to us-
Built to platform standards
Every plugin, app or extension is coded to the platform's own coding and review standards, so it passes marketplace review and stays stable across updates.
-
Security by default
Input sanitization, output escaping, nonce verification and capability checks are part of every build, not an afterthought before submission.
-
Clean integration with existing tools
Extensions connect to your CRM, ERP, payment systems and third-party APIs so data flows automatically instead of being re-entered.
-
Performance that does not slow the host
Poorly written plugins are the single biggest cause of slow WordPress and WooCommerce sites. We write lean code that does not add to the problem.
-
Marketplace-ready from day one
We build with Shopify, WordPress and Magento review guidelines in mind from the first commit, so submission is not a scramble at the end.
-
You own the code
Full IP assignment on every contract. The plugin, app or extension belongs to you outright, with no licensing fees on your own product.
-
Overlap with your hours
Three to four hours of daily overlap with US, UK and Canada time zones, so reviews and decisions happen in your working day.
-
Long-term compatibility
We keep your extension updated as platforms release new versions, so a WordPress major update does not break your site the next morning.
Questions, answered
Plugin & extension development FAQs
Which platform should I build my plugin or extension on?
It depends on where your users are and what problem you are solving. WordPress plugins reach the largest install base. Shopify apps target merchants on a growing platform with a clear monetization path. Chrome extensions sit inside the browser across any website. VS Code or Figma plugins target developers and designers. We recommend honestly after a short call.
Can you build a plugin or app to sell on a marketplace?
Yes. We build for the WordPress Plugin Directory, Shopify App Store and Magento Marketplace, handling the coding standards and review guidelines each platform requires so submission is not a scramble.
How much does plugin or extension development cost?
Most projects land between $3,000 and $40,000 depending on complexity and the number of integrations. A focused single-purpose extension sits at the lower end; a full Shopify app with billing and an admin interface sits higher. Every quote is itemized before work begins.
How long does it take to build a plugin or extension?
A focused single-feature extension typically takes 3 to 6 weeks. A multi-feature app with billing, settings and third-party integrations usually runs 8 to 16 weeks. You see a working build early and a demo every sprint.
Can you add features to an existing plugin or extension we already have?
Yes. We audit the existing codebase first, identify technical debt that needs addressing before adding features, then build on a clean foundation so new features do not introduce instability.
Do you build private plugins for internal use or only marketplace products?
Both. Many clients need a plugin that solves a specific problem on their own site or in their own Shopify store and has no need for a public listing. Private builds follow the same coding standards.
Will the plugin stay compatible when the platform releases new versions?
We code to current platform APIs rather than deprecated workarounds, which significantly reduces compatibility risk. Our maintenance plans also include testing and updates each time a major platform version is released.
What happens after the plugin or extension launches?
Every project includes a handover, documentation and a warranty window for fixes. Most clients move onto a maintenance plan covering platform compatibility updates, security patches and a bucket of improvement hours.
Ready to build a plugin or extension that actually holds up?
Tell us what platform and what problem. We will recommend the right approach, the realistic cost and the timeline, usually within one business day.
