Your systems finally talk to each other.
The problem
One customer, three versions of the truth.
When shop, CRM and accounting run separately, the same customer exists three times, in three different states. Someone reconciles that by hand at the end of the month.
ERP

Customer no. K-10412

After the integration: one record.
Changes travel to every system on their own. Nobody retypes, nobody reconciles.
How we connect
Four routes, one goal.
Which route fits depends on the systems and the volume of data. Often it is a combination.
Two-way sync
Changes on one side land on the other. Conflicts are resolved by fixed rules, not by chance.
Event-driven
An order, a payment or a status change immediately sets off the next steps.
Scheduled runs
For large volumes: nightly syncs with a report of what was transferred and what was not.
Bridge without an API
Systems without an interface can be connected too: through files, email inboxes or database access.
Typical connections
One event, four systems
One order. Everything else happens on its own.
This is what an integration looks like in daily use: one event in one system, and the others follow without anyone having to think of it.
Trigger
An order comes in through the shop
A customer completes the checkout. From here, the integration takes over.
Stock adjusted
The items are reserved and the ERP inventory is correct.
Draft invoice created
Line items, prices and customer data are already filled in.
Customer history updated
The purchase shows up in the CRM, so sales sees the current picture.
Shipping prepared
The label is created and the tracking number goes out to the customer.
Operations
Reliability is the actual job.
Building an integration is the smaller part. Keeping it running quietly for years is the bigger one.
Buffering instead of data loss
If a system is unreachable, transfers wait and catch up as soon as it is back.
Every transfer logged
You can look up at any time what was transferred, when, and where it went.
Alerts before anyone notices
If something gets stuck, we and you get a message. Not the customer.
Changes without downtime
New fields or systems can be added without breaking the running connection.
Common questions
Typical questions before connecting systems.
Usually yes. In that case we work with exports, file drops, email inboxes or direct database access. We assess how stable each route is and discuss it with you before we build.
No. Transfers are buffered and caught up once the system is reachable again. Afterwards, the log shows you what was recovered.
Either we do or your team does. You get documentation and access to the log. If you want, we take over monitoring and maintenance.
No. The code belongs to you, the connection runs in your environment, and the documentation is enough for others to keep working on it.
