Systems that talk to each other — instead of sitting side by side.
We build interfaces that connect your existing software: ERP, CRM, online shop, accounting. Instead of entering data manually in three systems at once, a clean API integration keeps everything in sync in real time. Built once — it runs automatically, with error monitoring and retry logic for production use.

Typical Challenges
Your sales team works in HubSpot, but orders and invoice status live in Weclapp. Result: sales reps constantly check the ERP for updates. A direct API sync shows real-time status without switching systems.
Your Shopify store shows "in stock" but Weclapp says zero. Customers order unavailable products — cancellations and frustration follow. Real-time ERP-to-shop sync prevents this permanently.
Every month, someone types invoices from ERP into your accounting software. 200+ invoices × 3 minutes = 10 hours of tedious work — with 2-3% error rate. An API connection does it in seconds, error-free.
Monthly reports require manual data compilation from 3-4 systems in Excel. It takes 3-5 days — every month. Integrated systems generate reports at the click of a button.

In Detail
Your systems should talk to each other — not turn you into a data courier.
Everyday life in a typical SME: copying data from Weclapp into the CRM, entering shop orders manually in the ERP, typing invoices from the ERP into the accounting software. That costs 200+ hours a month — and produces transfer errors that get more expensive with every knock-on mistake.
A professional system integration connects your tools seamlessly and in both directions: ERP ↔ CRM ↔ shop ↔ accounting. Data flows automatically, in real time, both ways. An order in the shop appears in the ERP immediately. The delivery status from the ERP shows up in the shop. The invoice flows into accounting automatically. Without a single manual step.
We integrate systems at API level — not via CSV exports or copy and paste. That means type-safe data transfer, error handling when an API fails, retry logic for uninterrupted operation and a monitoring dashboard that warns you proactively before data becomes inconsistent.
Typical integrations: Weclapp ↔ Shopify (stock and order sync). HubSpot ↔ Weclapp (360° customer view). DATEV/Lexware ↔ ERP (automated bookkeeping). Multi-channel sync (your own shop + Amazon + eBay in one central ERP). Every integration starts with a free process analysis.

Real Project
For fiber4net, a fibre optic provider, we built a bidirectional interface between Weclapp ERP and Shopify. Store orders automatically flow into the ERP; order status and tracking numbers flow back.
✓ 200+ manual exports per month eliminated. Order processing time reduced from 4 hours to 15 minutes.
Our Process
We analyse your current software landscape and find the weak points: where is data transferred manually? Where do double entries cause errors? Which systems have APIs, which need workarounds? The result is an integration roadmap prioritised by business impact.
We define how data should flow between the systems — with clear rules for priority, error handling and logging. Each interface gets a data model: which fields are mapped, which transformations are needed and how conflicts are resolved (e.g. when the same product has different prices in two systems).
Building the interfaces with extensive tests. We test edge cases before they show up in production: what happens on a timeout? With invalid data? When the third-party system updates its API version? Every integration has a staging environment for test runs with real data structures.
Step-by-step deployment with parallel operation: the integration first runs in shadow mode alongside the manual process until everyone involved is convinced. Then the full switch-over, with a monitoring dashboard that shows the sync status of every system in real time.
