Grocery App Development — Questions Answered
10 direct answers. No sales language.
Grocery app development in the UK typically costs £25,000–£70,000+ for a three-app platform (customer, picker, rider) with admin dashboard, depending on store count and integration complexity. Mtoag provides a fixed quote after a free scoping call.
A focused MVP with customer, picker, and rider apps takes 8–12 weeks from kick-off to launch. Multi-store platforms with real-time inventory sync across many locations take 12–18 weeks. Every project receives a fixed timeline in the Technical Specification.
Yes. Mtoag builds real-time inventory sync layers connecting existing POS and warehouse management systems to the customer-facing app via webhooks, so stock counts stay accurate without manual updates.
Yes. Substitution logic is built into both the customer app (preference settings) and the picker app (approval flow), so out-of-stock items are handled without cancelling the whole order.
With route-optimised dispatch and a well-staffed store, 20–30 minute delivery windows are achievable for local orders. The realistic minimum depends on store density, rider availability, and order volume — Mtoag scopes this during discovery.
Yes. Multi-store and dark-store architecture is standard — the admin dashboard manages inventory, orders, and dispatch across any number of locations from one screen.
Yes. All payment integrations use PCI DSS compliant processors (Stripe, Apple Pay, Google Pay) with tokenised card data — card details never touch Mtoag or client servers directly.
Yes, 100%. All source code, design files, and documentation created for your project belong to you from day one, written into every Mtoag contract as standard.
Yes. The dispatch engine assigns riders based on live location, current load, and delivery zone — reducing manual coordination and keeping delivery windows consistent during peak hours.
Every project includes a 30-day post-launch support window covering bug fixes at no extra cost. Ongoing maintenance, POS integration updates, and feature development are available on a monthly retainer.
