Quotes used to be assembled by hand from ERP data, price lists and emails. Today an internal tool produces the finished quote. checked, calculated, delivered as a PDF.
Costing tool + ERP integration
You bring the problem.
We build what you need.
Clesk is the engineering agency for companies whose processes no longer fit off-the-shelf software. We listen first, then we plan, then we build. software, automations and integrations that fit your business exactly. And we stay on it until it runs. And after that, too.
Every project starts with a sentence like this.

Diagnosis
Your systems are islands. Every bridge between them is currently a person with two screens. expensive, slow, and the main source of errors.
How we build it
We connect the systems through their interfaces, bidirectionally and fault-tolerantly. What used to be retyped flows automatically. with a log, so you can always see what was transferred when.
Outcome
Zero duplicate entry, no more transfer errors. and your people get back to their actual jobs.
What we do for you.
/01
Consulting & concept
We analyse your processes and tell you honestly what is worth digitising. and what isn’t. The result is a plan with priorities, effort estimates and sequence.

When no standard software fits your process, we build your own: internal tools, client portals, planning and costing tools. maintainable and fully yours.
Learn more →/03Automation
Recurring manual work disappears: booking invoices, syncing data, generating reports and documents. Runs at night, on weekends. without you.
Learn more →/04Integration
ERP, CRM, shop, accounting. we connect what currently runs side by side. Your systems stay, the duplicate entry in between disappears.

Why clients stay with us.
Principle 01
Understand first, build second.
Before the first line of code we look at your business. We don’t sell technology. we solve your problem. Sometimes the answer is: “You don’t need us for that.”
Principle 02
Fixed price, no surprises.
After the analysis you get a proposal with a clear scope, clear price and clear date. Changes are discussed before they cost money. not after.
Principle 03
Your code belongs to you.
Source code, access, documentation. all yours. No vendor lock-in, no dependency. You could continue with anyone else at any time. You just won’t want to.
Principle 04
We stay on it.
Software is finished when it runs. and it only runs when it’s looked after. Monitoring, updates, evolution: from one team, the one that built it.
What “solved” looks like here.
