When no existing plugin does what you need, or only half does it, we code it for your website, your process and your users. [Tell us what you need](https://baqueiro.es/en/contact/) ## Tired of solutions that “almost” work? Generic plugins solve generic problems. For what’s specific to your business, you need a tool made to measure. ### What you need is… - …a feature no plugin on the market offers. - …to replace five different plugins with a single lightweight solution. - …to connect your WordPress site to an external system (CRM, ERP, a supplier’s API). ### We build the plugin you’re missing We write WordPress plugins from scratch, following the platform’s coding and security standards. The result does exactly what you need, with no unnecessary options, and fits your website and the way you work. [ What for ] ## What kind of plugins we develop Most requests fall into one of these four categories. ### Integrations Syncing your website with a CRM, an ERP, a payment gateway or a supplier’s API, so data isn’t copied by hand. ### Replacing plugins Swapping several overlapping plugins for a single one that does just what’s needed, with less load and fewer conflicts. ### Business features Forms with their own logic, calculators, private areas, approval workflows: what your website has to do and no plugin does well. ### Custom WooCommerce Pricing, shipping or stock rules your shop needs and off-the-shelf extensions don’t cover. ## A custom plugin is an investment in performance and security Stacking generic plugins takes its toll on speed and security. Why your own solution works out better in the long run: ### Optimized performance A single plugin doing the work of five loads far less code, and that shows in the visitor’s experience and in your Google rankings. ### Security and reliability With code you control, there are no surprises: no unexpected conflicts and no risk of the author abandoning the plugin and leaving it without security patches. ### Exactly the right features The plugin does what you need, without confusing menus or options that only slow down your admin and complicate your team’s work. [ What’s included ] ## From requirement to installed plugin What’s part of every build, whether it’s a small plugin or a complex integration. - Requirements analysis and technical scope in writing - Development following WordPress best practices - A clear settings panel, in your language - Integration with APIs and external services - Clean, commented and optimized code - Compatibility and performance testing in a staging environment - Security to WordPress standards (nonces, permissions, data validation) - User documentation and help with installation [ Our own plugins ] ## What we sell, we also use This website runs on our own theme and plugins: the contact form, cookie and GDPR management, appointment booking and content for search engines and AI. Some of our plugins are for sale in our store. We also build custom internal tools.

It did this by hand and it took hours. ### The solution We built a plugin that connects to the CRM’s API. Every hour it checks for new properties, updates existing ones and removes those sold, with photos, prices and descriptions, with no human intervention. ### Results - Over 20 hours of work saved every month. - Properties updated on the website in real time. - No manual data entry errors. [I have a similar challenge](https://baqueiro.es/en/contact/) [ FAQ ] ## Common questions about plugin development How much does a custom plugin cost? It depends on the complexity. A simple plugin can take a few dozen hours; a complex integration with an external system, hundreds. That’s why the first step is always an analysis of the requirement, after which we give you a fixed quote. Will it be compatible with my theme and my other plugins? Yes. We follow WordPress best practices so it sits well with the rest of your website, and we test it in a staging environment that mirrors your site before installing it. What happens when WordPress updates? A well-written plugin survives normal updates without changes. When a new version of WordPress or PHP requires adjustments, we make them as part of a maintenance plan or as a one-off job. Do you offer maintenance for the plugin? Yes. Like any software, your plugin may need security or compatibility updates over time. Our [maintenance](https://baqueiro.es/en/services/maintenance-and-support/) plans cover that. Do I get documentation? Yes. We deliver commented code and a user guide for the settings panel, so you or any other developer can understand and maintain it. Can I sell the plugin you built for me? Yes. When the project is finished, the source code and intellectual property of the plugin are yours. You can use it, modify it or sell it as your own product.
