Custom integrations and APIs.
Connect your tools, your data, your systems. Without locking in to one vendor.
Custom integrations and APIs are the connective layer that makes your business tools talk to each other. We build custom APIs, webhooks, middleware and ETL flows so your CRM, ERP, shop and databases sync automatically, with no manual re-entry and no lock in to a single vendor.
Custom integrations and APIs are for Swiss SMBs and growing commercial companies already running several tools that do not talk to each other. If your team re-enters the same data twice, or you are preparing for automation and AI that depend on clean, connected data, this is the foundation to build first.
Your tools don't talk to each other. Your CRM ignores your ERP, your accounting ignores your shop, your forms ignore your databases. Every manual flow is wasted time and a source of errors.
We build custom integrations between your systems : custom APIs, webhooks, middleware, ETL. When a tool lacks a proper API, we build a layer on top. When a native connector is enough, we use it (Zapier, Make, n8n). We avoid excessive lock in to a single vendor.
Why disconnected tools cost you more than you think
Your tools do not talk to each other. Your CRM ignores your ERP, your accounting ignores your shop, your forms ignore your databases. Every manual copy and paste is wasted time and a fresh source of errors.
The hidden cost is not just the hours. It is the duplicate records, the orders that slip through, the numbers that never quite reconcile. As your business grows, those gaps widen until reporting becomes guesswork.
Take Legumes Express, a Geneva fresh produce distributor. Orders arrived through several channels and were retyped into the stock and invoicing systems by hand, which meant late deliveries and reconciliation that never quite matched. Once those flows were connected, the daily re-entry that used to swallow hours of an operator's morning simply disappeared, and the order errors that came with it disappeared too.
Custom integrations close those gaps for good. Instead of one more dashboard to check, your systems exchange data the moment it changes, quietly and reliably, in the background.
- Manual re-entry between CRM, ERP and accounting eats hours every week.
- Disconnected systems create duplicate and conflicting records.
- Off the shelf connectors break the day a tool lacks a proper API.
- Vendor lock in turns a small change into an expensive migration.
Our approach to custom integrations and APIs
We start from your real workflows, not from a connector catalogue. The goal is a layer that fits your business, that you own, and that does not trap you with one vendor.
Custom integrations and APIs connect your business systems so data moves automatically and accurately. We design and build custom REST or GraphQL APIs, webhooks for real time bidirectional sync, middleware that decouples your systems, and ETL pipelines that consolidate your data. When a tool lacks a proper API, we build a clean layer on top of it. When a native connector is genuinely enough, we use it, with Zapier, Make or n8n, rather than over engineering. Everything ships with monitoring and alerting, so a broken sync is caught before it reaches your team or your clients. On a typical two system sync we see manual re-entry drop close to zero and copy related errors fall sharply, freeing several hours a week per operator. The result is a connected stack you control, sized for a Swiss SMB or a scaling commercial team.
- Map the workflows and the data that actually move between teams.
- Design the contract: custom REST or GraphQL APIs with clear schemas.
- Build the connective layer: webhooks, middleware, ETL where each fits.
- Reuse native connectors (Zapier, Make, n8n) only where they hold up.
- Wrap a custom API layer around tools that lack one.
- Ship monitoring and alerting so failures surface fast.
- Document everything so your team stays independent.
What you get with MAWT
You get a connected stack, not a pile of brittle scripts. Each integration is built to be observed, maintained and extended, by us or by your own people.
Because we are Geneva-based and work as an extension of your team, there are no intermediaries and no layers between you and the senior humans building your integrations. You know exactly what runs and why.
It is the same playbook we ran for Legumes Express: scope the flow that hurts most, ship a sync that holds up under real daily volume, then extend it once it proves itself. You feel the time saved in the first weeks, not after a year long platform project.
- Custom REST or GraphQL APIs designed around your data.
- Webhooks and bidirectional sync that keep systems in step in real time.
- Middleware that decouples your systems so one change never breaks the rest.
- SaaS connectors when relevant, custom layers when they are not.
- Monitoring and alerting so issues are caught before you are.
Who custom integrations are for
This service fits Swiss SMBs and growing commercial companies that already run several tools and feel the friction between them. If your team keeps re-typing the same data into two systems, you are ready for it.
It is equally relevant when you are adding automation or AI on top of your stack: clean, connected data is the prerequisite. Integrations are the plumbing that makes everything downstream reliable.
- Teams losing hours to manual data transfer between tools.
- Businesses preparing for automation or AI that need clean data first.
- Companies wary of being locked in to a single vendor.

Native connector vs custom integration
| Native connector (Zapier, Make, n8n) | Custom integration and API |
|---|---|
| Fast to set up for standard, supported tools | Built around your exact workflows and edge cases |
| Breaks when a tool lacks a proper API | We build a clean API layer on top of any tool |
| Logic and ownership sit inside the vendor | You own the layer and the logic |
| Per task pricing scales with volume | Predictable cost once built, no per action fees |
| Limited control over error handling | Monitoring and alerting built in from day one |
Custom integrations connect your CRM, ERP, shop and databases so data syncs automatically.
We build custom APIs, webhooks, middleware and ETL, and use native connectors only where they fit.
When a tool lacks a proper API, we build a clean layer on top of it.
For Legumes Express, connecting the order and stock flows removed hours of daily re-entry and the errors that came with it.
Every integration ships with monitoring and alerting and no excessive vendor lock in.
Connected, clean data is the prerequisite for any automation or AI you add later.
