Sites and systems built around the process.

Websites, online shops, apps and management software built for the way the company already works — not for whatever the template allows.

Where operations seize up

Companies grow. Spreadsheets do not

01

Data scattered everywhere. Customers in one file, orders in another, the rest in WhatsApp threads. Nobody can answer a simple question without opening four things.

02

Manual work repeated. Copying from the site into the invoicing software, from invoicing into the spreadsheet. It is time paid for twice and the door errors come in through.

03

Programs that do not talk to each other. Each tool solves its own piece and none of them shows the whole. The company's overview lives in two people's heads.

04

Held hostage by an off-the-shelf system. You pay a licence every month for features you never use, and the one you actually need is always missing.

A sample of our work

Design before code

Nothing goes into development without being designed and approved screen by screen. That is the phase where changing your mind is still cheap.

What we build

Four fronts, from the site to the whole operation

Some are done in weeks, others live for years and grow with the company. In the diagnosis we separate what is urgent from what can wait.

01 — Building from scratch

Website creation

The website is the only channel that is truly yours. Social media, portals and ads are rented ground — the rules change and your reach evaporates. The site stays, as long as it loads fast, gets found and takes visitors through to contact.

  • Structure built for SEO from the first page
  • Bespoke design, no bought template
  • Speed and Core Web Vitals measured before delivery
  • Content management so your team publishes without calling us

02 — Building from scratch

Online shops

Selling online is not putting products on a page. It is stock that adds up, shipping that does not eat the margin, a short checkout and a back office someone can work in every day without suffering.

  • Catalogue, variants and stock management
  • Payments and shipping wired to what you already use
  • Checkout cut back to the essentials so you do not lose the basket
  • Connection to invoicing and couriers

03 — Systems and operations

Mobile apps

An app is justified when there is repeated use, work away from the desk, or a need for notifications and offline operation. When none of that applies, a site that sits well on a phone solves it better and costs less.

  • An app for iOS and Android from a shared codebase
  • Installable web apps when the store is not worth it
  • Fieldwork with syncing afterwards
  • Publishing and follow-up in the app stores

04 — Systems and operations

ERP and management systems

Customers in one place, orders in another, invoicing in a third and the rest in spreadsheets only one person knows how to open. Bringing it all into a single base is what turns reports into decisions.

  • Customers, quotes, orders and invoicing connected
  • Dashboards with what matters to each role
  • Stock, scheduling and HR as the case requires
  • Migration of the data you already have, without starting from zero

No small print

What stays yours when the project ends

A system only the supplier can touch is not a company asset, it is a chain. That is why this is written down before we start, not after.

Ownership · what we hand over with the project

Code

Source delivered and documented

It lives in a repository in the company's name. Another team can pick it up without asking us anything.

Data

Exportable database

It comes out in an open format whenever you want, without asking anyone's permission.

Access

Everything in the company's name

Domain, hosting and accounts created in your name from day one.

Licences

No rent for the software

You pay for what you use — hosting and third-party services. The system itself carries no compulsory monthly fee.

Manual

Documentation with the project

How it is put together, where it is hosted and what to do when something goes wrong.

Team

Training before go-live

The people who will use it learn before the system replaces what was there. Nothing is forced on anyone.

What we work with

Technology chosen by the problem

There is no favourite language. There is the one that solves the case, that someone can still pick up in five years, and that does not tie the company to a single supplier.

How we work

From the first sketch to a working system

At the end of each phase there is something you can see and test. There is never a long stretch where the client only gets news.

Phase 01

Diagnosis

We walk through the current process with the people who run it every day, not just with those who describe it.

Process mapped

Phase 02

Architecture and design

Screens designed and linked together. Changing your mind here costs no development.

Clickable prototype

Phase 03

Development

Built in parts, with a working version in testing at the end of each one.

Version in a test environment

Phase 04

Delivery and evolution

Data migration, team training and follow-up after going into production.

System in production

Frequently asked questions

What people ask us before going ahead

There is no price list, and be wary of anyone who has one. The price comes from how many processes the system has to cover, the integrations needed and how many user profiles exist. What we do is budget in phases: a first useful version with the essentials, and the rest later, with the system already paying its way.

A corporate website and an ERP with six modules do not live on the same timescale. After the diagnosis we give you a phased calendar, with dates for each delivery instead of a single date at the end — so you see the work moving instead of waiting in the dark.

Not always. When there is a ready-made program that fits, we say so and help install it — it is cheaper and more honest. Bespoke development is justified when the process is what sets the company apart, or when the licences for several programs already cost more than building what is missing.

In most cases, yes. Invoicing software, CRMs, online shops, couriers and banks usually have an API. When they do not, there are other routes — file imports, scheduled tasks — and we tell you up front if any of them is fragile.

It migrates. It is one of the most laborious parts of the project and the one we give most attention to, because a new system with incomplete data loses the team's trust in the first week. We run the migration in a test environment first and only go live once the company has validated it.

No. The code, the database and the hosting access are yours and they come documented. If one day you want to change supplier, another team can pick the project up. We carry on because the work is worth it, not because there is no way out.

Smart diagnosis

Get a plan before you leave your details

One minute No commitment

It is not a contact form under another name: every answer changes the next question — and it asks for no details at all to start.

  • The questions adapt to what you answer
  • At the end you get the concrete places to start
  • If you would rather talk now, WhatsApp answers in under an hour

          A flawless system with nobody arriving is still a system standing still

          Building is half the job. The other half is getting the right people there — and that is with us too.
