Service

There is no standard product for your task. So we build one that does exactly what you need.

Custom software development for companies with 5 to 250 employees. AI agents are part of this software: with the permissions of their role and a human who approves.

Starting situation

Does this sound familiar?

  • Your business model has a peculiarity that no software reflects. You have tried add-ons, macros and workarounds. Now nobody can hold it all together any more.

  • Your qualified employees spend 60% of their day looking things up, gathering information and passing it on.

  • You want to use AI in your company, not as a window that answers questions, but as something that gets tasks done.

    What an AI employee is
  • A module you need cannot be bought: four-eyes payment approval, goods receipt with a weighing record, an invoice with the mandatory details for your industry.

Why off-the-shelf software fails at your peculiarity

Standard software reflects the average; at the decisive points, your company is not average. The usual options: adapt to the software or live with workarounds. Both cost you every day.

At W&K Connect, custom software development means: we first write down how your workflow really runs and who decides what, and then build the software around your peculiarity, not the other way round. This is how modules, interfaces and AI agents come about for companies with 5 to 250 employees, and you own the source code we develop for you. Process first, software second. → How we work

Approach

How custom software development works with us: from the task to a running system

  1. 01

    Task and logic (1–2 weeks).

    What should the software or the agent do, and what not? Where does the data come from, where do the results go, who approves? We write it down, you sign it off.

    1–2 weeks

  2. 02

    Building in stages (from 4 weeks, each stage 2–4 weeks).

    After each stage you see something that works, not slides.

    from 4 weeks, each stage 2–4 weeks

  3. 03

    Deploying AI agents.

    One agent per role that works in your ERP or CRM and in the document storage, and opens the case when a call comes in.

  4. 04

    Proving.

    Before: time per case, error rate, lead time. After: the same numbers. Then you decide on the rollout.

  5. 05

    Operating and developing further.

    Software that runs is never finished. We stay on it: updates, new requirements, new roles.

Result

What you own at the end: running software, AI agents and the source code

  • Software that reflects your logic: web applications, ERP and CRM modules, interfaces, portals, mobile applications for the warehouse and field service.

  • AI agents per role that work in your systems according to your rules and identify themselves as AI.

  • A separate memory per customer, kept apart from every other.

  • You own the source code we develop for you. It comes with documentation that another developer understands, so that you are not dependent on us.

  • Operation in a German data centre or on your own infrastructure. Critical data is processed offline and locally; we connect external language models only for non-critical data and only as processors under Art. 28 GDPR.

What we have already built, without customer names

  • Custom ERP modules that could not be bought: four-eyes payment approval, goods receipt with a weighing record, an invoice with a reverse charge note.

  • A telephony connection that opens the caller in the system and files the call note with the case.

  • AI agents in more than 20 roles in several companies, including at our own company in management and accounting, each with its own memory and its own permissions.

Examples

Typical starting situations for custom development

Example scenarios, sorted by type of workflow. The industry is only an example in each case.

Sales or CRM with a peculiarity, for example buying from customers with valuation.

Pricing follows rules that are not in any software. We build goods receipt with the weighing record, pricing logic and supporting document in one case.

Trade & precious metals

Production or maintenance, for example asset history.

The experience of the master technicians is not written down anywhere. An agent for maintenance knows the asset history and maintenance plans and answers the new colleague.

Manufacturing & mechanical engineering

Service or telephony, for example a service provider with many calls.

A call comes in, the customer opens in the system, the call note goes to the case, the callback becomes a task.

Warehouse, for example food.

A mobile module for order picking and goods receipt, built for a few actions per item.

Food & logistics

Your process is different? That is exactly where we start. → First call

What we work with: systems, devices and interfaces

Odoo, Bitrix24, SAP Business One, HubSpot, our own developments; scales, label printers, scanners, telephony, banking, online shops. We use whatever solves your task, not tied to any vendor.

For whom custom development pays off

Companies with 5 to 250 employees that have a task no standard product solves, or that want to use AI agents as a working role rather than as a chat window.

Every AI agent identifies itself as AI (EU AI Act, Art. 50). We do not use AI that evaluates employees, recognises emotions or makes personnel decisions. If we process personal data on your behalf, we conclude a data processing agreement (DPA) with you under Art. 28 GDPR. → AI transparency

Frequently asked questions about custom development

When is custom development worthwhile instead of standard software?

Custom development is worthwhile if your peculiarity affects the heart of your business (pricing, goods receipt, project workflow) and the workaround costs time every day. If the peculiarity lies at the margins, a module in the existing system is often enough.

Who owns the source code?

You own the source code we develop for you. It comes with documentation that another developer can use to continue the work.

How does ‘building in stages’ work, and what do we see when?

After each stage of 2–4 weeks, you see something that runs: a module, a screen, an interface. You test it with real cases and steer the next stage.

Can we start with a pilot for one process?

Yes, a pilot for one process is the usual start: a fixed scope, one number before and the same number after.

How do custom software and AI employees fit together?

The AI employee is a component that we place in your software or your ERP: one agent per role, with memory and permissions. What it may do and where it stops is defined by the permissions and approval concept.

What does it cost to operate a custom development?

The running costs of a custom development depend on who operates it (we or your IT), how many AI roles are working and how many interfaces need to be maintained. We give you a price range in the first call.

What the price depends on: → Pricing & pilot models

What an AI employee may do and where it stops: → AI employees

→ All questions

Next step

Describe the task for which nothing suitable exists. In the first call, we tell you whether existing building blocks are enough or custom development is the more honest route, and where a first milestone lies.

30 minutes, one process from your daily work, no slides.

We build new where what exists is not enough, and combine what exists where building new would be wasteful. Your task decides, not the catalogue.
