FAQs

Should we buy an app or build one?

We compare existing options against the actual workflow, data access, integration needs and ongoing cost. Custom development makes sense when there is a specific gap worth owning.

Can the app connect to an ERP or warehouse?

Yes, subject to the target system’s available interfaces. We define the source of truth, identifiers, failure handling and reconciliation before building the connection.

What access will the app need?

Permissions are mapped to the agreed features and reviewed with your team. We avoid requesting access that the implementation does not need.

Can you distribute the app to other merchants?

Distribution changes the implementation and review requirements. We agree whether the app is for your business or a broader merchant audience and check the current platform requirements before scoping release.

Who operates the app after launch?

Hosting, credentials, monitoring, incident ownership and API maintenance are assigned in the handover. An ongoing support engagement can be agreed separately.

Will this change the customer checkout?

Only when checkout behaviour is explicitly in scope and supported by the store’s setup. An operations app can work entirely behind the storefront.

Which task still needs a spreadsheet?
