The problem
Two applications both claim to be current. Staff retype the record, and a change in one never reaches the other.
System and API integration
Connect the applications you already run.
When two systems both claim to be current, we connect one flow at a time and leave the rest in place. A rewrite is not the integration.
- KeepThe applications that already run
- ConnectOne flow, with a failure path
- AfterSomeone is told when a sync stops
Orders
- Customer
- Total
- Status
Accounts
- Same customer
- Same total
- Same status
A change in Orders is sent to Accounts. If it fails, a person is told. No live order is created.
Illustrative. The real payload is agreed from the systems you already run.
Where an integration starts
The first conversation is the record that has to exist in two places, not a new platform.
The hidden cost
The wrong total, the missed status, and the person who copies between screens. Both systems still load.
The outcome
One flow keeps those fields together. You can see the payload, the failure path, and who is told when a sync stops.
How a connection actually gets built
Three parts. The other applications stay where they are.
1 · The systems
The two applications you already run, including an ERP, a shop, mail, or a product we host. We do not replace them to connect them.
2 · One flow
The fields that must match, the direction, and what happens when the other side rejects the record. Other flows wait.
3 · After
A log and a person who is told when the sync stops. That care is a separate agreement. A rewrite stays on application modernisation.
What you can check
You can open the connection before it is left running.
- Field list
- Which values must match, and which system is the source for each.
- Payload
- A sample of what is sent, using realistic data, with secrets removed.
- Failure path
- What happens when the other system is down or rejects the record.
- Alert
- Who is told, and how the failed item can be sent again.
- Contract
- Scope, credentials handling, and later flows as separate lines.
Where this sits
Related work you can open. Measured client results are shared only with permission.
- Application modernisationWhen an older application should stay, and only one module should move.
- Workflow automationWhen the gap is a repeated hand-off, not a missing connection.
- Enterprise applicationsWhen the two systems should become one application.
- Spreadsheets to softwareWhen one side of the flow is still a workbook.
- Ecommerce engineeringWhen the shop and the back office do not share stock or orders.
- Product catalogueSystems a connection can sit on, instead of a new platform.
After launch is scoped separately
An API can change shape, and a sync can stop while both screens still load. Care means a named owner and a way to see the failed item. We do not promise uptime.

We reply with the one flow we would connect first, what we would leave in place, and who would be told when it stops.
