Save money inside your business, not just on the shopfront.
Siebweb builds custom dashboards, CRMs, internal tools and automated workflows from 1,500 € net, AI-accelerated and human-reviewed, that save your business time and money on the work customers never see.
A website brings customers in. Custom software fixes what is slow, manual and expensive inside your business: the admin, the bookings, the follow-ups, the reporting nobody has time for. We build it with AI, so you get real, working tools at a fraction of what an agency dev team would charge.
Internal dashboards
Your numbers, bookings and jobs in one place, instead of five spreadsheets.
Custom CRM
A pipeline shaped to how you sell, so no lead or follow-up is ever dropped.
Automated workflows
Bookings, reminders, follow-ups, invoicing. The repetitive stuff, handled.
Connect what you use
Stitch your existing tools together so data stops living in silos.
Support and internal chat
Shared inboxes and team tools that keep everyone on the same page.
A fraction of agency rates
AI-built, human-checked. Real software without funding a twelve-person team.
Bring us the problem. We build the solution.
Every business runs on a handful of processes that are slow, manual or scattered. Tell us where it hurts, and we build the exact tool that fixes it. Here are the ones we are asked for most.
The problem
Your data lives in five spreadsheets and three apps, and nobody trusts any of them.
We build: a unified database and dashboard
One source of truth. Your numbers, jobs and customers in one place, always current, so decisions stop being guesswork.
The problem
Leads and clients slip through the cracks because you track them in your head and your inbox.
We build: a custom CRM
Shaped to your actual pipeline, not a generic tool you fight with. Every lead, follow-up and deal, visible and never dropped.
The problem
Customer questions arrive by email, WhatsApp, Instagram and phone, and things fall through.
We build: a customer support tool
A shared inbox or simple help desk that pulls every channel into one queue, so nobody waits and nothing is missed.
The problem
Your team coordinates over private WhatsApp chats and lost email threads.
We build: an internal chat and coordination tool
One place for your team to talk, assign and track work, tied to your own data instead of scattered across apps.
The problem
Invoicing and bookkeeping eat hours, and things get forgotten or paid late.
We build: invoicing and bookkeeping tools
Invoices generated and sent, payment reminders on autopilot, and figures that reconcile themselves. Fewer late nights, fewer mistakes.
The problem
Bookings, reminders and follow-ups are all done by hand, every single day.
We build: automated workflows
The repetitive work runs itself, bookings, reminders, follow-ups, reports, so your team gets its hours back.
Stop doing by hand what software should be doing for you.

It runs on a server you own and control. Your data, your rules.

We support and evolve it
Tools are living things. We keep yours working and grow it as your business changes.
Real software at a fraction of agency dev rates.
Because we let AI do the heavy lifting, not a twelve-person team. Already have a website with us? This is where it gets interesting. Not sure yet? Start with a website, the low-risk way to see how we work, then grow into the tools that save you money inside.
From 1,500 €, scoped to exactly what you need.
Fixed, transparent prices. No hidden fees. No long lock-in contracts.
Common questions, straight answers.
What does custom software cost?
From 1,500 € net, scoped to what you need. We quote line-item and transparent, so you know the price before you say yes.
How is it cheaper than an agency?
We let AI do the heavy lifting and a human own the quality, so there is no twelve-person team for you to fund. Real tools, a fraction of the cost.
Do I need a website with you first?
No. If you already have one with us, this is the natural next step, but you can start here. Not sure? Start with a website, the low-risk way to see how we work.
What exactly can you build?
Unified databases and dashboards, custom CRMs, customer support tools, internal chats, invoicing and bookkeeping tools, booking and reminder workflows, and Google review automation. If it is a repetitive internal process, we can usually build a tool for it.
Can you connect my existing tools?
Yes. We stitch what you already use together so your data stops living in silos and starts flowing where it needs to.
Who owns the software?
It runs on infrastructure you own and control. Your data, your server, your rules.
Do you keep supporting it?
Yes. Tools are living things. We keep yours working, patched and evolving as your business changes.
