Custom software for your business.
Built from ready-made modules – affordable, and it belongs to you.
When an off-the-shelf product is no longer enough and an agency is too expensive, there is a third way. We build you a system from proven modules that fits your workflows – not the other way around.
At some point, the patchwork just isn't enough
A growing business needs more than a website and an invoicing program. Customer data, quotes, orders, routes, contracts, employees, working hours – it all starts in Excel, then turns into a patchwork of tools that know nothing about each other. Every piece of information gets typed in two or three times.
There are three common answers to this problem – and all three have a catch:
- Cobbling together five to ten SaaS subscriptions. Low entry cost, but the tools don't integrate, data is scattered across different providers, and nothing can be customised. You work the way the software dictates.
- Buying a large standard software solution. Powerful, but oversized, expensive, with months of rollout – and you adapt your business to the software, not the other way around.
- Having custom software built by an agency. A perfect fit – but costs five figures, because every time you start from scratch.
The made-to-measure option in software
Think of clothing:
- Off the rack is standard software and SaaS kits – available immediately, low entry cost, but it never fits quite right.
- The bespoke suit is full custom development from scratch – a perfect fit, but expensive and time-consuming, because every piece is made by hand.
- We are the made-to-measure option in between. Proven patterns – our ready-made modules – are tailored to your business. The result fits excellently, but costs only a fraction of the bespoke suit.
The best of both worlds: the fit of custom work at a price that is achievable for a mid-sized business. Possible because we don't start from scratch – we build on our own, proven foundation.
Why this works
Custom-fit, but affordable
The standard modules are ready. You pay for the customisation and the individual parts – not for reinventing CRM or invoicing.
One system instead of a patchwork
A customer is created once and flows through all modules – quote, order, route, invoice, contract. One login, one database, everything interconnected.
The software adapts to you
You don't have to squeeze your workflows into the constraints of a standard software. We map how you actually work – and build on top where a standard module isn't enough.
It belongs to you
Self-hosted on your own server with a German hosting provider. Code and data belong to you, in standard formats, migratable at any time. No subscription lock-in.
It grows with you
You start with the modules you need today and add more later. No "all at once" project, but a system that scales alongside you.
The building blocks
Six standard modules are ready to go – selected, configured and customised for your business as needed
CRM
Manage customers and contacts centrally, email integration, address matching, duplicate checking. The cornerstone that all other modules connect to.
Order & Invoice
From order to invoice in one seamless flow – including e-invoice (XInvoice / ZUGFeRD), PDF generation, payment tracking and export to your accountant.
Sales
Manage leads and opportunities in pipelines, follow-up reminders, activities. So nothing falls through the cracks.
Route Planning
Plan appointments and assignments, optimise routes, mobile view for field staff. Born from real-world use.
Employees
Personnel master data (encrypted), absences, working hours, documents. Sensitive data with extra protection.
Contract Management
Store contracts, track terms and deadlines, automatic reminders before cancellation and renewal dates.
And what the standard modules don't cover, we build on top
This is exactly the part that turns the toolkit into your solution: a special approval workflow, an interface to an industry portal, a report that doesn't exist anywhere else, a process that only runs this way in your business. Standard modules and custom modules run in the same system, with the same data, one login – no break between "standard" and "custom".
Where it helps, the modules come with AI support – classifying documents, summarising texts, extracting data. Structured according to our principle: simple routine tasks via local models on your side (no data leakage), demanding tasks optionally via more powerful models. You decide how far the AI reaches outward.
From patchwork to system
Markus' landscaping and gardening business ran on Word, Excel, a whiteboard and paper notes. Step by step, a system emerged: first the CRM, so all customers are in one place. Then quotes, orders and invoices – an accepted quote becomes an order with one click and later an invoice. Then route planning, which accesses the same orders. The crews now log their hours on mobile instead of paper slips.
A customer is created once – and appears everywhere they're needed. Markus no longer calls anyone back with "let me check on that."
One family, one foundation
Our ready-made products are built on the same foundation as your custom solution. Whether you start small with a website (OpitzWorks: Page), use a ready-made specialist product (Care, Archive), or need your own system right away – you grow within one family instead of having to piece together isolated solutions later. And as with everything we build, this holds true: code and data belong to you, are hosted with a German provider, and can be migrated at any time.
There is deliberately no fixed price – because it is custom-made. The price depends on which modules you need and how much individual work is involved. The key point: the standard modules are already built, so you pay for selection, setup and the custom parts, not for reinventing standard features. That is exactly what makes custom-made affordable here. We'll work out the specifics in a free conversation.
That's true for a complete new development – and that's exactly what we don't do. The standard modules are ready. You pay for the selection, the setup and the individual parts, not for reinventing CRM or invoicing. That's why custom-made is affordable here.
You can – if your workflows are exactly as the software intends. Usually they aren't, and then you end up adapting your business to the software instead of the other way around. Add to that often high costs, lengthy rollouts and a cloud where your data resides. Our system maps how you work, and the data stays with you.
Quite the opposite. Being small means you don't need enterprise-level features, just exactly what fits you. And that's precisely what makes the modular approach affordable. You start with one or two modules and grow from there.
You keep everything. Code and data belong to you, stored in standard formats on your own hosting. The system keeps running, even without us, and another developer can take it over – it is based on widespread, long-lived technologies, not obscure ones.
