Your ERP does 80%.
You compete in the other 20%.
You feel the gap between your ERP, your CRM, and your actual business process. That's where competitive advantage lives. We help you to close it.
Trusted Clients
No more adjustment of your internal processes to the limitations of your ERP
Your ERP handles procurement. Your CRM tracks customers. But between them? Spreadsheets. Workarounds. Manual data transfers. And that one person who "just knows how it works."
You didn't get into business to become a software company. But the software gap is costing you in speed, in errors, in opportunities your competitors are catching first. Sound familiar?
Disconnected Systems
No real-time data flow between ERP, CRM, and operations. Every handoff is a manual step.
Too many Excel Files
Spreadsheets, copy-paste, and "that one person who knows" - fragile, slow, error-prone.
Costly ERP Customization
Six-figure SAP quotes. 14-month timelines. And every SAP upgrade breaks your changes.
Competitive Blind Spots
While you reconcile data, competitors with connected systems make faster decisions.
The missing LINK between your systems.
You can have a software that is customized for your internal processes giving your team one seamless experience with single sign-on and real-time data. Easy, affordable and on predictable way. No hidden costs.
Your ERP
SAP, Dynamics, etc.
The missing LINK
One login. Real-time data.
Your CRM
Salesforce, HubSpot, etc.
Other Systems
MES, WMS, BI, Legacy
No More wait
Your team signs in once and works across all connected systems without noticing the boundaries. One login. Every system. Zero friction.
No More Yesterday's Data
Pull, transform, and transfer data between your ERP, CRM, and any other system. Not last night's export / import. Right now.
No More Working Around Your Software
Not a plugin. Not another SaaS subscription. Software designed around exactly how your business operates - because no off-the-shelf product was.
No More Vendor Lock-In
Runs on your infrastructure. Under your control. No recurring license you can't walk away from. You own it. Completely.
Five phases. No surprises. You pay when we deliver
No software development experience needed. Every phase has clear deliverables, a fixed price, and a decision point where you choose whether to continue.
Discovery: 1–2 days, on-site
We come to you. We sit with your team, the people who actually use the systems. We map workflows, identify gaps, and document exactly what needs to be built. You walk away with scope, timeline, investment and technical feasibility before a single line of code is written.
✓ You Receive
Detailed Product Requirements Documentation: scope definition, architecture recommendation, realistic timeline, and fixed budget for the next phases.
What This Protects You From
Building the wrong thing. Underestimating complexity. Starting without knowing the real cost. Endless costs due to paying hourly rates without clear scope.
Proof of Value: Typically 4-6 weeks
First Working Version: Typically 6-10 weeks
Alpha Release: Typically 4-6 weeks
Production Launch: Typically 2-4 weeks
You pay when we deliver. Not before.
You pay when we deliver. Not before.
Every phase has a fixed price and a clear deliverable. If we don't deliver, you don't pay.
"Our invoices say 'delivered,' not 'hours worked.'"
| PHASE | DELIVERABLE | PAYMENT |
|---|---|---|
Discovery | PRD (Product Requirements Documentation) | ✓ On delivery |
Proof of Concept | Technical Feasibility | ✓ On delivery |
MVP | Working Software | ✓ On delivery |
Alpha | Complete Feature Set | ✓ On delivery |
V1.0 Launch | SLA Based Production Deployment | ✓ On delivery |
Your people design the product. From day one.
Your end users are involved at every phase. They're not learning a new system - they are designing one with their needs.
Discovery: They show us the real workflows
Your operators, salespeople, and warehouse staff, the ones who know the workarounds and the frustrations.
MVP: They test it with real tasks
Not in a demo environment. With real data, real scenarios, real pressure.
Alpha: They refine it
Feedback becomes features. Edge cases become handled. Friction becomes flow.
Launch: They champion it
Adoption is natural because your team was part of building it. No change management crisis.
We deliver on time because we don't guess.
Each phase eliminates a category of risk. By the time we're building V1.0, there are no surprises left. That's not optimism. That's a decade of developed process.

Everything you need to know before your first custom software project.
Before You Start
No. Most of our clients haven't, and that's the point.
You know your operation. You don't need to know software. Our process exists so the people who understand your daily work, not a technical team, can describe what's broken, and we handle everything from there.
Every phase has a defined deliverable, a fixed timeline, and a decision point where you choose whether to keep going. You're never asked to guess what comes next.
That's the first thing we settle together, before you spend real money.
In Discovery we map your actual workflows against what your current systems can already do. Sometimes the answer is configuration, not code. If it is, we say so, and you'll have spent 1-2 days getting that clarity instead of six months building something you didn't need.
Custom software earns its place when your process is your competitive edge and no off-the-shelf tool models it accurately. The clearest signal: your team works around your ERP instead of with it.
The difference shows up the day your ERP upgrades.
Customizing SAP means changing the system from inside its own limits, and every upgrade can break what you changed. Custom software is a separate layer built around your process. It connects to your ERP through APIs, reads and writes data in real time, and doesn't depend on the ERP's architecture.
The practical version: ERP customization is quicker for small tweaks but turns expensive and fragile at scale. Custom software is more flexible, fully yours, and survives ERP upgrades without rework,
For a typical mid-market integration, plan on roughly 4 to 6 months from Discovery to production.
Discovery is 1-2 days on-site. Proof of Concept runs 2-4 weeks. MVP development takes 6-10 weeks. Alpha refinement adds 4-6 weeks. Production launch is 2-4 weeks.
Those are working estimates. Discovery gives you the real number, specific to your systems, your complexity, and how fast your team can move with us.
We come to you for 1-2 days and sit with the people who actually run the systems. Not just management. Operators, sales, warehouse, anyone who touches the process.
We watch the real workflows, map the software, tools, and plugins you use, ask a lot of questions, and document where your systems fall short of what the business needs.
You don't prepare technical documentation. You make the right people available for a couple of hours a day, the ones who know the workarounds and the "we've always done it this way." They're our most valuable source.
You walk away with a Discovery Report: scope, an architecture recommendation, a realistic timeline, and a fixed-price proposal for the next phase.
Technical Details
If it has an API or a database we can reach, we can connect to it.
For DACH companies that usually means SAP (S/4HANA, ECC, Business One), Microsoft Dynamics, Sage, proALPHA, or abas on the ERP side, and Salesforce, HubSpot, Dynamics 365, or Pipedrive on the CRM side. We also connect to warehouse management, MES, document management, BI tools, and proprietary legacy applications.
An older system with no modern API isn't a dealbreaker. We've integrated with systems older than the internet. We confirm feasibility during the Proof of Concept, before you've committed to a real budget
Your team logs in once, with the credentials they already use (Active Directory, Azure AD, Google Workspace, or any SAML or OAuth2 provider), and reaches the custom solution and every connected system without logging in again.
To the person using it, it feels like one system. Underneath, the software authenticates against each connected platform securely and in real time.
Your choice, and we build for both.
Many DACH clients keep it on-premise or in a private cloud for data sovereignty and compliance, and we fully support that. The software runs on your infrastructure, under your control, with no data leaving your environment unless you decide it should, and no dependency on our servers.
Prefer cloud? We deploy to your provider of choice: AWS, Azure, or any EU-based cloud.
Data sovereignty isn't a feature we add later. It's a decision we make on day one.
The software is GDPR-native and NIS2-ready by design: your data stays inside your infrastructure boundaries, every integration runs over encrypted connections, and access controls and audit logging are built in from the start. No external dependencies that quietly create compliance exposure.
Your compliance and IT security teams get full documentation.
We pick the stack that fits your environment, your team, and the problem, rather than forcing one we prefer.
For integration work that usually means .NET, Java, Node.js, or Python on the backend; React, Angular, or Vue on the frontend; REST, GraphQL, SOAP, and message queues to connect systems; and Docker, Kubernetes, and CI/CD underneath.
We decide during Discovery and document every choice, so you can always see why.
Very little, by design.
Because the custom solution talks to your ERP through APIs instead of modifying it internally, an ERP upgrade means we update the integration layer, not the whole application.
Planning a full replacement, say SAP ECC to S/4HANA? We can build the solution ERP-agnostic from the start, so the switch takes minimal rework.
Process, Cost & Risk
Every phase has a fixed price and a defined deliverable, and you pay when that deliverable is finished and accepted. Not before.
No hourly billing. No timesheets. No invoices for "work in progress." Discovery is paid on delivery of the Discovery Report. Proof of Concept on successful technical validation. The same through MVP, Alpha, and V1.0.
If we don't deliver what was agreed, you don't pay. Our invoices say "delivered," not “hours worked.”
Yes, and you keep everything.
Every phase is built to stand on its own. Stop after Discovery and you leave with a full report. Stop after Proof of Concept and you know whether the integration is technically feasible.
At any exit point you own all of it: code, documentation, architecture decisions. No lock-in. No penalty for stopping.
Scope changes happen on every project. What matters is having a process for them.
Ours: every change runs through a structured evaluation. We assess the impact on timeline and cost, lay out your options, and you decide. Nothing gets built without your explicit sign-off.
And because Discovery and MVP testing validate assumptions early, surprise changes are rare to begin with.
You have three options. We maintain it under a support agreement with defined SLAs. Your team maintains it, and we hand over fully documented code plus training. Or a hybrid, where your team runs day-to-day and we handle the complex changes.
The software is built so any competent development team can maintain it, not only us. You're never locked into working with us. You keep working with us because it makes sense.
Why Intertec
You could. But hiring experienced integration engineers in the DACH region takes 4-6 months, and onboarding and aligning them takes another three.
That's close to a year before a single line of production code exists, and you'd be running a software team, which isn't your business.
We bring a team that has built this kind of solution for over a decade, with proven processes and architecture patterns. You reach production faster, at lower risk, without permanently growing headcount for a one-time need.
Five things, and they're the five things our competitors can't put on their own website.
You pay on delivery. Milestones, not hours. Our invoices say "delivered."
Discovery comes first. 1-2 days understanding your business before we propose anything, which kills the assumptions that turn into expensive mistakes.
The team stays. Under 5% turnover on long engagements. The engineer who maps your systems in Discovery is the one who deploys the solution.
Your data stays yours. On-premise where you need it, GDPR-native, NIS2-ready by default.
We know your world. Product companies, ERP integrations, and how your end customers experience the result. We don't need six weeks to learn your industry.
Our home market is the DACH region and Western Europe. We work in English and German, and our delivery teams run on Central European time.
Based elsewhere but your needs line up with what we do? We're glad to talk.
Getting Started
Thirty minutes. No pitch, no slides.
We ask about your systems, what's hurting, and what you're trying to reach. You ask us anything. By the end we'll both know whether this is worth exploring, and if it is, Discovery is the next step.
That's exactly what Discovery is for.
It's low-commitment and fixed-price, built to give you clarity: what's possible, what it costs, what the timeline looks like, whether or not you go forward with us.
Worst case, you walk away with a professional assessment of your systems and a clear recommendation. Most clients find that worth having, no matter what they decide next.
