Services · Custom software & portals

Software that fits your process. Not the other way round.

Sometimes there is no program that fits your process, and the heart of the business is a spreadsheet. Then we build you an internal portal or your own program, small and made for exactly your purpose. It runs in your accounts. Checks and updates are optional. Code and data belong to you.

What we actually do

Start small, made for exactly your purpose, and stay with you afterwards.

Internal portals

One place for orders, systems, appointments or documents, in the browser and on the phone. Your team and, if you like, your customers can access it.

Small programs

A tool for exactly one purpose: costing quotes, planning materials, documenting inspections.

Services without a screen

Some tasks need no screen, only an interface that other programs or agents use. Whether with a user interface or without, we decide case by case.

Connected to your programs

What we build exchanges data with accounting, ERP or shop. Nobody retypes between old and new.

Care on request

We set everything up in your own accounts. They belong to you; we are only invited. If you like, we keep an eye on things for a monthly fee. It is not required.

Typical examples

This is what it looks like in typical businesses. These are examples, not customer cases.

Trades · Building services

Maintenance contracts

TodayMaintenance contracts, systems and appointments are kept in a spreadsheet. Inspection reports are filled in on paper and typed up.

AfterwardsTechnicians see systems, appointments and inspection reports on their phones. Customers get their reports in the portal.

Trade · Specialist wholesale

Special orders

TodaySpecial orders for customers run on notes and emails. Nobody knows for sure what has been ordered, delivered or collected.

AfterwardsA small program shows every special order with its status. When the goods arrive, the customer is notified automatically.

Services · Surveyor’s office

Reports and site visits

TodayOrders, site visits and reports are kept in three programs and a calendar.

AfterwardsAn internal portal brings together order, appointment, photos and report. Everyone in the team sees the status.

How it works

In the customer portal after launch: see every step and approve the commission before we implement it.

  1. 01

    Describe

    In the customer portal after launch: You describe what the program should do and upload your current list or examples.

  2. 02

    Proposal

    We get back to you with a proposal: what gets built first and how it works with your programs, at a fixed price per result.

  3. 03

    Approval

    You review the description and approve it in the portal. We split larger projects into small steps that you approve one by one.

  4. 04

    Build and hand over

    We build, test with real data and move over your existing data. We hand over the program with documentation in your accounts. Care is optional.

How you engage us

You can engage us for custom software in three ways. With fixed prices instead of open timesheets.

Consulting

We clarify whether you really need custom software or whether an existing program is enough, and describe what would need to be built.

Implementation

We build, test with real data and hand everything over documented. Code and data belong to you.

Care on request

We set everything up in your own accounts. They belong to you; we are only invited. If you like, we keep an eye on things for a monthly fee. It is not required.

Is this right for you?

A good fit if …

a spreadsheet is the heart of your business, you cannot find a suitable program for your process or standard software forces you into detours.

Not a good fit if …

a good program for your purpose already exists. Then we would rather set up that program than build something new, and we tell you so up front.

More about advice

Frequently asked questions

Who owns the software?

You do. Code, data and documentation belong to you. You can also have someone else look after the software later.

Where does the software run?

In your own accounts, in the cloud or on your server in Germany. Data is stored on servers in the EU. You own the accounts; we are only invited.

What happens to our spreadsheet?

We move the data into the new program and check it with you. Until everything is right, the spreadsheet can keep running.

Isn’t ready-made software cheaper?

Often it is. That is why we first check whether a suitable program exists. We only build what you cannot buy in that form, and we start small.
