In short
What custom
development means.
Custom development is software built around your business instead of the other way round. Baslon Digital builds web apps, portals, internal tools and integrations, and connects bookings, payments, CRMs and automations to your website so that admin runs itself. If a ready-made tool would do the job, we'll say so. Every project starts with a free call, and the scope and price are agreed before work begins.

Practical software,
built around you.
From a single integration to a bespoke app, the aim is the same: remove the manual work and make the next step easy for your customers and your team.
Internal tools
Tools that replace spreadsheets and repeated manual steps for your team.
Third-party integrations
Connections between your website and the services you already rely on, such as CRMs and payment providers.
Bookings, payments and automations
Bookings, payments and follow-up wired into your site so that admin runs itself.
Wix custom development
Custom functionality for Wix and Wix Studio websites where the standard features aren't enough.
Improvements to existing builds
Fixes, testing and new features for a site or app that already exists.
Is it the right choice?
Custom isn't always
the answer.
We'd rather recommend the simpler option when it serves you better.
Choose custom when
Existing apps and plugins can't do what you need, or you're working around their limits with spreadsheets and manual steps.
Choose off-the-shelf when
A ready-made tool already does the job. It's usually quicker and more affordable, and we can help you set it up and connect it.

What is custom development?
Custom development means building software or features around your specific needs instead of relying only on ready-made tools. It can be a web app, a customer portal, an internal tool, or a connection between the systems you already use.
When do I need custom development rather than an off-the-shelf tool?
Usually when an existing app or plugin can't do what your business needs, or when you're working around its limits with spreadsheets and manual steps. We'll tell you honestly if an existing tool would do the job, because that is often cheaper and quicker.
Can you build on top of my existing Wix website?
Yes. We work with Wix and Wix Studio and can extend a site with custom functionality and connect it to third-party services. We'll confirm what is realistic on Wix for your project during a free call.
Can you connect my website to a CRM, payments or booking system?
Yes. Connecting bookings, payments, CRMs and automations to your site so that admin runs itself is a core part of our work. The right approach depends on the tools you already use.
How much does custom development cost and how long does it take?
It depends on what is being built, so we don't publish fixed prices or timescales. After a free call we agree the scope, price and schedule in writing before work begins.
Will I own what you build?
We agree ownership, hosting and access arrangements in writing before work begins, so there are no surprises later.
Do you provide support after launch?
Yes. We offer ongoing updates, testing and fixes so your site or app keeps improving after launch. You can also choose to look after it yourself.
