Custom WordPress Plugins
A custom WordPress plugin that adapts your site to your business
We build bespoke WordPress and WooCommerce plugins for companies that need something more than a ready-made plugin from the catalogue. If your site, store or sales process requires its own form, calculator, configurator, API integration, client panel or automation — we will prepare a solution tailored exactly to the way you work.
We do not install yet another heavy plugin that does “everything and nothing”. We design a feature that is meant to solve a specific problem: to speed up customer service, simplify sales, automate repetitive tasks or connect WordPress with the other systems in your company.
- A plugin for your specific process
- 100% your code — no subscriptions
- No unnecessary features or conflicts
- Compatibility with WordPress updates
- API integrations: CRM, ERP, wholesalers
- Code documentation + 60 days of support
When it makes sense
- off-the-shelf plugins do not solve your problem
- you use several plugins just to get one feature
- the site runs slowly because of an excess of add-ons
- you need an integration with an external system
- your company’s process is non-standard
- you want to own the code
- WooCommerce needs modifying for your model
- you care about a solution without recurring licences
Off-the-shelf plugins do not always fit your process
Most ready-made WordPress plugins are built with mass use in mind. They have dozens of features you do not use but which still weigh down the site, the admin panel and the database. The problem arises when your company needs a specific action — its own quote form, a price calculator, a connection between WordPress and a CRM or non-standard WooCommerce logic.
In that situation, adding more ready-made plugins often only complicates the system. A custom plugin lets you do exactly what you need — without unnecessary features, conflicts and pointless subscriptions.
When an off-the-shelf one is better
- a ready-made plugin solves the problem well
- the plugin is stable and lightweight
- it does not require many workarounds or modifications
- the cost of the licence is much lower than a custom build
- the feature is standard (CF7, WPForms, GravityForms)
We do not push custom code for the sake of it — if a ready-made plugin is enough, we will tell you straight.
What does a custom WordPress plugin give you?
You are not buying “a piece of code”. You are buying a solution to a process that today takes up your team’s time, generates errors or blocks further sales.
More control over your site
You do not have to adapt your company to the limitations of an off-the-shelf plugin. The plugin is built around your process, your customers and the way your team works.
Less manual work
A custom plugin automates repetitive tasks: notifications, recalculating prices, generating enquiries, importing data and syncing with other systems.
Faster customer service
If the customer can calculate a price, configure a product, send a complete set of data or check the status of their case themselves, your team spends less time on repetitive questions.
Better sales
A calculator, a configurator or a well-designed form can shorten the path from interest to enquiry. The customer understands the offer faster and finds it easier to decide.
A more stable solution
Instead of combining several random plugins, you can build one module that achieves a specific goal. Fewer conflicts, easier maintenance.
No dependence on licences
Your own plugin can work without recurring external licences. The code is prepared for your site and can be developed further.
What we can build for you

Benefit: You move part of your customer service into the panel, and the customer gets quick access to the most important information.
Examples of custom plugins
Concrete scenarios in which a custom plugin solves a real business problem better than any ready-made plugin from the catalogue.
Service quote calculator
For companies with a variable price that depends on parameters — area, dimensions, location, number of products, service variant or additional options.
WooCommerce product configurator
For stores selling products with many variants — made-to-measure furniture, bundles, packages, personalised elements or technical products.
B2B enquiry form
For companies collecting specific enquiries from business customers — with attachments, option selection, company details and automatic assignment to a department.
WooCommerce integration with a wholesaler
For stores automatically fetching products, prices, photos, descriptions or stock levels from an external source (XML, API, BaseLinker).
Client panel
For companies giving customers access to files, case statuses, documents, order history or individual information after logging in.
Order handling automation
For stores automatically changing statuses, sending notifications, passing data to other systems or generating sales reports.
What you get as part of building a custom plugin
The work is not just code. It is process analysis, a specification, logic design, programming, testing, documentation and post-deployment support.
Process analysis
- establishing exactly what the plugin should do
- who will use it
- what data should flow through it
- integrations, roles, scenarios
Benefit: We know whether you need a simple module, an integration, a panel or a larger system inside WordPress.
Functional specification
- views and fields
- user roles
- dependencies and conditions
- notifications and integrations
- use cases
Benefit: Before coding begins you know exactly what will be built.
Logic design
- the process flow from the customer’s side
- the process flow from the administrator’s side
- validation and error handling
- optimising the UX of the panel
Benefit: The plugin does not just “work” — it is practical in day-to-day use.
Plugin programming
- PHP 8.4 + WordPress Plugin API
- JavaScript / REST API
- WooCommerce API and hooks
- webhooks and WP-CLI
- code compliant with WPCS standards
Benefit: A solution tailored to the site, with no unnecessary features or random workarounds.
Testing on a staging environment
- tests of forms and data
- tests of permissions and roles
- tests of conflicts with other plugins
- user scenarios
- 2 rounds of fixes included
Benefit: A lower risk of problems after the plugin goes live on production.
Deployment on the site
- installation on production
- configuring how it works
- data migration (if needed)
- checking the integrations
- verifying correctness
Benefit: A finished solution working on the real site, not just in tests.
Documentation and instructions
- a user guide (PDF)
- technical documentation (Markdown)
- inline-commented code
- a short usage recording (optional)
Benefit: You are not dependent on one person — the plugin can be developed and serviced in the future.
Post-deployment support
- 60 days of post-deployment support
- minor fixes and questions
- fine-tuning how it works
- a plan for further development
- optional ongoing care
Benefit: You have time to test the plugin in real work, not just in a test version.
How the collaboration works
Six stages — from the functional brief, through the specification and development, to deployment, documentation and 60 days of support after launch.
Functional brief
Mapping: what exactly the plugin should do, how it should behave and what it should integrate with.
Effect: You know that no one is quoting “blind” — first we understand the process.
Specification and quote
We present a technical specification + a final quote with a schedule.
Effect: You accept a specific scope of work and know the final cost before we start.
Development
We code the plugin, test it on a staging environment and show you progress.
Effect: You see the work as it happens and can raise comments along the way.
Testing and fixes
Tests with your team, with 2 rounds of fixes included in the price.
Effect: The plugin is polished before it reaches production.
Deployment and documentation
Installation on production, code and usage documentation, training.
Effect: You can use the plugin from day one, without getting lost in the panel.
60 days of support
Minor fixes, questions and fine-tuning of how it works in real use.
Effect: We respond to the things that only come to light in everyday work.
How much a custom plugin costs
The price depends on the number of features, integrations, views, user types, data sources and the level of testing. Before quoting we prepare a short functional brief in order to define the scope well.
The four most common levels of complexity in our practice:
| Scope | Examples | Who it is for | Net price |
|---|---|---|---|
| Simple plugin | one specific feature: a form, a simple calculator, additional fields, a small automation | companies with a single narrow problem to solve | from PLN 500 net up to PLN 1,500 net |
| Medium plugin | an extended quote calculator, a product configurator, a larger form, a WooCommerce module | sites and stores with a more complex process | from PLN 1,500 net up to PLN 3,000 net |
| API integration | connecting WordPress with a CRM, ERP, wholesaler, warehouse or courier system, webhooks | companies connecting WordPress with another system | individual net quote |
| Panel / custom system | a B2B client panel, a request-handling module, an extended workflow with roles | companies needing a larger module inside WordPress | individual net quote |
The final price depends on the number of features, integrations, views, user types, data sources, the level of testing and the scope of documentation. The quote is fixed — we do not surprise you with extra costs along the way.
Plugins ready for SEO and AI models
A custom plugin can support technical SEO if it is well designed. Your own module can generate optimised subpages, structured data, indexable content, automatic linking, FAQ sections, product catalogues, landing pages or technical elements that support visibility.
If the plugin generates content, subpages, FAQs, catalogues, configurators or product data, we design them to be readable not only for the user, but also for Google and AI models (AI Overview, AI Mode). A well-prepared data structure helps AI systems better understand the offer, product variants, customer questions and the hierarchy of information.
When designing plugins we make sure they do not create chaos in indexing: correct URLs, controlled noindex, canonicals, structured data and the impact on Core Web Vitals.
What we watch in the code
- URLs and structure
- indexing and noindex
- canonicals
- H1–H3 headings
- loading speed
- structured data
- compatibility with SEO plugins
- impact on Core Web Vitals
- the way content is generated
