Custom web development that keeps you moving

You get a clear definition of what a feature should do before we write code. We walk through your current process: who enters information, where does it go, and what result does the customer expect? An inquiry form might require a staff review before sending anything to the CRM. That decision shapes development more than the appearance of the form.

We document the required data, who can access it, and what stays outside the first version. We assess existing services for their capabilities and limits. A small integration may be enough, preventing a specific request from quietly turning into a complex platform.

For a new feature, we establish which data it actually needs and when that data can be removed. An inquiry should not automatically leave complete customer records in several systems. We review the purpose of each field and agree on what gets sent to a connected service. You define retention requirements based on your business process and obligations; we translate those decisions into technical behavior.

Our tests include deletion. Does an inquiry disappear only from the screen, or also from active storage and connected systems? Backups may have a different retention period, which we document explicitly. We also check error logs for unnecessary personal data. That keeps a useful integration manageable when someone asks to correct or delete their information.

An integration should respond clearly when another system does not answer. We check the API documentation, access permissions, and available test environment before building the connection. We then establish which source is authoritative. If inventory can change in two places, for example, we need to know which system determines availability and when the website retrieves that information again.

We have built this for clients. For Verhuurwinkel, several API integrations connect the client's ERP system and Storyblok directly to the frontend. The products come straight from the ERP. For Figur, a custom booking flow sends visitors to Crossuite or, for some specialists, to Calendly.

We test missing data, expired access, and duplicate messages. Where retries are safe, we configure them; where they could create duplicate requests, we add protection first. You know which errors staff can handle and which need technical investigation. For sales processes, we coordinate this with the online store.

You can review the main feature before we build every variation. We start with a small working version using representative examples, anonymized where needed. For a calculator, that includes empty fields, invalid values, and rounding. For search, we check what visitors see when nothing is found. We test behavior, rather than only checking whether a button responds when clicked.

We separate testing from production and agree on the checks required for acceptance. The frontend gets appropriate fields, useful error messages, and as few unnecessary scripts as possible. For content-rich sites, an Astro website can provide the foundation; features that need a server get a separate, suitable hosting setup.

After delivery, you should know how the solution works and who can intervene. We document important data flows, settings, and external services. We grant access only where needed; secret keys do not belong in the browser or a shared design file. You get an explanation of what you can manage, such as copy or notification addresses, and what requires a technical change.

Before launch, we establish how to restore a previous code version and what that means for stored data. New API versions and changes to your business process may require later adjustments. Our website maintenance arrangements define which checks continue and how we review further work before carrying it out.

Custom web development means building features and integrations around your process, instead of bending your process to fit a theme or plugin. It makes sense when standard software forces an awkward process, creates excessive manual work, or sends visitors to another tool unnecessarily. One well-built integration or inquiry flow may be enough. We ask for a specific example of the problem: which data are you retyping, which step fails, or which information must a customer currently piece together themselves?

We first define the data, failure scenarios, and management boundaries. Then we test the smallest working part with real examples, making expansion an informed decision. If an existing service or plugin is reliable enough, we prefer to use it. You do not need custom software for a problem that already has a good solution. Comparing freelancers and agencies?
