Grocery delivery platform development.
Grocery has problems that ordinary e-commerce does not.
Grocery delivery is not a normal store. Items are sold by weight so the final total differs from the basket. Stock is genuinely perishable. Customers need substitution preferences because something will be out. Deliveries run in slots with finite capacity, and someone has to physically pick the order in an efficient route around the shop.
What’s included
- Delivery slots with per-slot capacity limits
- Weight and measure-based pricing with final-total adjustment
- Substitution rules and customer preferences
- Picking lists ordered by store layout
- Driver assignment and route planning
- Real-time order tracking for the customer
- Age-restricted item handling at handover
Slot capacity is the constraint
You can only deliver what you can pick and drive. Slot capacity has to reflect real picking and driving throughput, and close automatically when full — otherwise you promise deliveries you cannot make.
Substitutions decide whether they order again
Something will be unavailable. Whether the customer accepts a substitute, wants a refund, or would rather you called, has to be captured per item at ordering. Getting substitutions wrong is the most common reason grocery customers do not come back.
Common questions
How is weight-based pricing handled?
Estimated at checkout, adjusted at picking, with the customer notified and only the actual amount charged.
Can drivers use an app?
Yes — a mobile-friendly view with their route, order details and proof of delivery.
Can customers track their delivery?
Yes, with live status and driver location where you want to expose it.
