Availability changes between browsing and picking.
Define where stock is owned, when it is reserved and how unavailable items or substitutions are communicated to the customer.
Build grocery commerce, internal tools and connected workflows with a team that knows what happens between the basket and the doorstep.
Discuss your next projectGrocery software needs to connect the customer experience to a changing physical operation. Availability can move while an order is being picked; a substitution affects the basket; delivery capacity changes the promise a store can make. These details shape the application and the systems behind it.
Retter brings grocery and quick commerce experience to customer apps, ordering platforms, operational tools and integrations. A new tool can start from a short description of the problem. Our role is to understand the business rules and connections that make it useful in the daily operation, as we do today for istegelsin, CarrefourSA, A101 and Spinneys.
Define where stock is owned, when it is reserved and how unavailable items or substitutions are communicated to the customer.
Connect store selection, service areas, capacity and order status so the application reflects the fulfillment model.
Create focused operational views for picking issues, missing information and customer decisions, with clear ownership of the next action.
The first project does not have to replace the entire grocery platform. It could make substitutions easier to manage, connect a stock feed, improve a customer journey or give store teams a shared view of exceptions. We identify the people involved and the systems that own the relevant records before defining the release.
For a wider platform build, the same questions extend across catalog, price, payment, picking and delivery. We work through how those systems exchange information and how the operation responds when information is delayed or incomplete. Testing should include the difficult everyday cases, not only a successful order.
AI can help interpret a shopping request, prepare a response or summarize operational information. The task needs appropriate product and order data, clear limits and a way for the team to check the result. Stock commitments, payment changes and customer communication require explicit rules about who or what can act.
Our industry knowledge helps identify those boundaries. The goal is to improve a real workflow while preserving accountability for the customer promise. A conversational interface is one possibility; a reliable integration or a better staff tool may be the more useful first step.
