If you have built essentially the same JTL-Wawi integration for several clients, a JTL Cloud App may let you maintain shared business logic once and configure merchant-specific differences instead of deploying separate copies. The change does not replace Wawi: in the model described by JTL-Software Engineering, each merchant keeps Wawi local and connects it to JTL Cloud. The trade-off is that you take on app hosting, uptime, maintenance, and separation of each merchant’s data.
How to tell whether an integration is reusable
Review recent client projects by the problem they solve, not by the names of the customers. A repeated request is a useful starting point, but it is not enough on its own: the core workflow should be stable while merchant-specific mappings or thresholds can be handled as configuration.

- The same need has come up with multiple clients.
- The central logic remains similar even when field mappings, thresholds, or preferences differ.
- The workflow is not dependent on one merchant’s unusual process.
- A merchant could understand the app’s purpose and value from a listing without first needing a bespoke sales meeting.
Examples include accounting exports, shipping and label workflows, reporting dashboards, marketplace-specific data preparation, and stock or purchasing alerts. These are product ideas, not confirmation that a particular JTL API scope supports each one; check the relevant current JTL documentation before designing around an API capability.
What changes when you move it to a JTL Cloud App?
The proposed model connects a merchant’s local JTL-Wawi installation to JTL Cloud, which in turn connects to the Cloud App. The merchant does not have to replace Wawi. The app owner supplies and operates the cloud application; the merchant still needs the local Wawi API connection running for the app to work with Wawi data.
#1 Best Overall
JTL-Software Engineering’s article states that the setup requires JTL-Wawi version 2.2.0 or higher, a JTL ID to connect Wawi to JTL Cloud, and the JTL-Wawi API started with cloud connectivity enabled. Treat that version and setup as the article’s stated prerequisite, not a guarantee of current compatibility: verify the current requirements and setup instructions with JTL before implementation. JTL-Software Engineering’s article says: “Your Cloud App can only work with JTL-Wawi data when the required JTL-Wawi API connection is running.”
How to test the idea before public distribution
Start with a workflow you already understand
Choose a willing existing client whose integration is already in use. Define the shared workflow and identify which client-specific values can become configuration rather than separate code paths. Package that workflow as a private app and share it with specific merchants using activation codes, as described in the JTL-Software Engineering article.
Use a second merchant to test reuse
Add another client with a different setup. If supporting that client requires changing core logic for every merchant, the product may still be too bespoke. If the differences fit configuration, you have stronger evidence that one app can serve more than one merchant. This is a practical validation step, not a quantified test or guarantee of market demand.

The article proposes submitting a proven app for public App Store review after testing it across merchant setups. It says private apps avoid the public review path, but it does not establish current review rules or timelines. Check JTL’s current app distribution requirements before planning a launch.

Compare a shared app with repeated bespoke deployments
| Decision area | Separate client deployments | Shared Cloud App |
|---|---|---|
| Installation and maintenance | Each client deployment creates its own installation, update checks, and support work. | Shared application logic can reduce duplicated deployment work, while the app owner maintains the shared service. |
| Client differences | Differences can be handled in client-specific code or configuration. | Mappings and other merchant-specific settings need to be configuration; shared logic should remain in the app. |
| Access and support | Support may require access and knowledge tied to each client’s environment. | The app owner supports a cloud service, but each merchant still depends on an available local Wawi API connection. |
| Operations and data | Responsibilities are distributed across the separate deployments. | The app owner is responsible for shared hosting, uptime, monitoring, maintenance, and keeping each merchant’s data and configuration separate. |
| Distribution | Work is delivered directly to each client. | Private sharing can be used for validation; public distribution involves an App Store review path described by the article. |
| Revenue and services | Implementation and support can be sold per client. | The app can coexist with onboarding, customisation beyond the standard product, and consulting on surrounding workflows. |
This is a qualitative decision framework, not a cost comparison: the source provides no deployment-cost or revenue figures.
What operating responsibilities come with the app?
- Hosting and uptime: the app owner must keep the cloud application available. Managed hosting and basic monitoring may help, but they are not automatically included in the JTL Cloud App model described here.
- Monitoring and maintenance: you are responsible for detecting and addressing service issues and maintaining the app as the integration evolves.
- Merchant isolation: keep each merchant’s data and configuration separate. The JTL tenant is an important part of mapping a merchant to the corresponding records in your own app.
- Connection support: Wawi remains local, so the merchant’s API connection must be running and configured for cloud connectivity when the app needs Wawi data.
These duties are part of the product decision, not incidental deployment details. A shared app may reduce duplicated client deployments while concentrating service and tenant-isolation responsibility in the app owner.

Productising an integration does not require ending client services. The source identifies onboarding assistance, customisation for needs outside the standard app, and consulting on related workflows as possible services alongside the product.
