In brief
Before development, document the entire order journey, from payment through delivery to returns.
Plan the workflow first
Define product types, the inventory source, delivery methods and payment solutions. Multiple countries, currencies or subscriptions may introduce different technical requirements.
Trace a sample order through every system involved. Where is data copied manually? Who handles a stalled process? These questions determine the integrations needed.
Platform and extensibility
Alongside ease of use, consider update options, integrations and total ownership costs. Plugins and external services may introduce additional fees and dependencies.
In the test environment, check product variants, inventory changes, failed payments and refunds. An attractive product page does not replace a working order flow.
Launch and security
Cart and checkout caching need particular care in a purchasing flow. Back up before updating and test core journeys in the payment provider’s official test environment.
Consult an expert on privacy, consumer protection and billing requirements for the relevant market. The technical implementation should follow those approved requirements.
Operating costs
Budget for hosting, domains, maintenance, payment costs and licenses. Content updates and customer support time are part of ongoing operation too.
After launch, monitor purchase errors and inventory consistency. A successfully submitted request does not always mean an order has been fully processed.
- Goal: a specific business task and acceptance criteria.
- Testing: mobile journeys, forms and integrations.
- Handover: documentation, access and an operational owner.
