Calculators with your own rules
Base prices, surcharges, quantities or distances: inputs and calculation rules are defined so that results can be checked against agreed examples.
BAUVERIS / Software
Custom WordPress plugins and software for your workflow
Need a feature built around your own process? BAUVERIS develops custom WordPress plugins, calculators and focused web applications. We define the inputs, business rules, data and integrations before development. TransferCalc, our own WordPress product, shows how a fare calculator and ride enquiry workflow can work together.

Built around your task
Forms and administration views
Multi-step enquiries, conditional fields and appropriate status views can support a defined workflow. We plan which data is stored and who can access it.
Integrations with existing services
Where a suitable API is available, data can be sent or retrieved. Access, documentation, running costs and failure behaviour are clarified in advance.
What we agree before development
- Inputs, rules, outputs and the limits of the required feature.
- The existing WordPress and PHP versions, theme, plugins, hosting and an appropriate test environment.
- Data fields, permissions, retention requirements and required integrations.
- Concrete use cases and expected results for acceptance.
- The scope of installation, documentation, handover and future support.
Custom development costs
Calculation rules, interfaces, data, integrations and testing determine the development effort. We provide a proposal for the agreed scope after clarifying the requirements. Hosting, external API fees, licences and later extensions are identified separately. Buying TransferCalc provides the described product; commissioning a custom plugin is a separate service.
Packages and pricing scope ↗Turn a defined workflow into a testable feature
When does a custom WordPress plugin make sense?
A custom plugin can be appropriate when existing extensions do not fit your business rules or enquiry process. We first consider whether configuration, an existing extension or a focused custom implementation can solve the task.
If the application should run independently of WordPress, a separate web application may be more suitable. The workflow, users and existing technology guide that decision.
Testing, documentation and handover
We define examples with expected results, including valid and incomplete input, calculation boundaries, permissions and unavailable external services. These cases support checking the agreed features in the test environment.
Planning also covers installation, configuration, usage guidance and known limits. Source code delivery, usage terms and future maintenance are set out in the proposal.
PORTFOLIO
TransferCalc: our own WordPress plugin development
TransferCalc
The task: calculate transfer fares using defined rules and collect non-binding ride enquiries. BAUVERIS developed TransferCalc as its own WordPress product.
The plugin connects vehicle classes, pricing rules and surcharges to an enquiry form. Its administration view supports status management and CSV export. Fixed routes can work without Google; optional Google services require your own credentials and may incur external charges.
TransferCalc is shown here as an example of our development work. It does not confirm bookings or provide payment processing or driver dispatch. Product features and requirements are explained on its product page; a custom application is planned separately.

Common questions
What do you need to assess a custom plugin?
Describe your current process, the required feature and an example with inputs and the expected result. WordPress and PHP versions, installed plugins and available integrations are also helpful. Any required access is arranged afterwards.
Do I need an existing WordPress website?
A WordPress plugin needs a suitable WordPress installation. Hosting, the theme and existing plugins are considered during planning. If the website also needs to be built, the website and plugin can be scoped as separate parts of one project.
Can you build a calculator or an enquiry form?
Yes, for a clearly defined task. We agree the calculation rules, required fields, validation and expected results. Data storage, email delivery or transfer to another service are included only as agreed parts of the scope.
How is the functionality checked before handover?
We agree use cases and expected results, then check the implementation in the agreed environment. Depending on the feature, this includes invalid input, permissions and unavailable integrations. Acceptance criteria and documentation are defined in advance.
Will I receive the source code, and can the software be extended?
Source code delivery, usage terms, documentation and third-party components are addressed in the proposal. Future extensions are assessed against the existing architecture and additional effort, then agreed separately.
Are updates and maintenance included?
Updates, compatibility checks and ongoing support are agreed for the application. TransferCalc has the product-specific terms described on its product page; these do not automatically apply to custom development projects.
Can AI features or external APIs be integrated?
For a suitable task, we can plan an external service integration. We clarify API availability, data permissions, ongoing costs and failure cases. Large ERP, CRM or dispatch systems are not automatically part of the service.
