Denes Deli Sandwich App

Our client runs an independent deli known locally for award-winning sandwiches, salad bowls, and a wide range of customisable lunch items. With a loyal customer base and a busy lunchtime rush, they needed a faster, simpler way to take custom orders without the back-and-forth of phone calls and emails.

The brief was clear: replace the manual ordering process with a digital experience that gives customers full menu access, lets them customise every order, and delivers a clean, standardised order to the kitchen. In under a month, we delivered a working web app ready for real customers.

Where the Client Was Before Shape

The client already offered click and collect, but the existing setup had clear limits:

  • The current system only offered their most popular sandwiches and salad bowls, with no real customisation
  • Custom orders required customers to phone or email, creating friction at peak times
  • There was no way for customers to save favourites or quickly reorder a previous order
  • Every custom order was handled manually, slowing service and making consistency harder for the kitchen

They needed a single digital flow that handled custom orders end-to-end, freed up staff time, and made repeat ordering effortless for regulars.

What Shape Delivered

We worked with the client using our rapid product development approach, the same process behind our Product Accelerator, and shipped a working web app in under a month.

Product strategy and MVP scope

We started with a focused discovery session to map the existing ordering journey and pinpoint exactly where customers and staff were losing time. From there we scoped a tight MVP around the highest-value features: full menu customisation, fast sign-in, order history, and favourites. Anything that did not directly serve those goals was deferred.

End-to-end ordering experience

We designed a simple, guided journey covering sign-in, building a custom order, scheduling collection, and confirming with the kitchen. The user flow replaces what used to be a phone call or email back-and-forth with a single, structured process that customers can complete in under a minute.

Standardised orders for the kitchen team

Every order is converted into a clean, colour-coded confirmation email so the kitchen receives a consistent, easy-to-read summary instead of phone notes or scattered messages. Categories are visually grouped, removing the manual interpretation that used to slow service at peak times.

Frictionless customer accounts

Sign-in is passwordless: customers receive a one-time code by email and log in with a single tap. There are no passwords to reset and no friction blocking a hungry customer mid-order, while accounts remain secure. Saved order history and favourites make repeat ordering effectively one tap.

Digitised Process
We moved a fragmented manual process into a structured digital and automated solution
Rapid MVP
We delivered this app to the client in less than 4 weeks

A scalable technical foundation

We built on a modern, lightweight stack chosen to ship quickly without painting the client into a corner:

  • Flutter for the front end, so the same codebase can be extended to iOS and Android when the client is ready, without a rewrite
  • Python for a modular backend, split into focused services that stay maintainable as features are added
  • Supabase for authentication and data, including the OTP feature powering passwordless sign-in
  • Jinja2 for structured, templated confirmation emails
  • Railway for development and production hosting, giving the client a stable, low-overhead setup with room to scale

The result is an MVP that is genuinely production-ready and built to grow, not throwaway code that will need replacing in six months.

Key Features We Shipped

The live app includes:

  • Passwordless OTP sign-in - log in with an email code, no passwords to remember
  • Full menu customisation - build any sandwich, salad bowl, or order combination from the full menu in a single flow
  • Order history - every order is automatically saved and one-tap reorderable
  • Favourites - save favourite items and add them to any order with a single tap
  • Auto-generated confirmation emails - structured, colour-coded order summaries sent to the deli and copied to the customer
  • Direct customer communication - the confirmation email creates a shared thread between the customer and the deli for any follow-up

For customers, ordering a custom lunch is now as fast as picking from a saved list. For the business, every order arrives in the same clean format, removing the guesswork of phone notes and scattered emails.

The Results

The project delivered concrete outcomes for the client:

  • Working product in under a month, from discovery through to a deployed web app
  • A full custom ordering flow that replaces phone and email orders end-to-end
  • Standardised, structured orders delivered to the kitchen as colour-coded summaries
  • A cross-platform-ready codebase, so the same product can be extended to iOS and Android without a rewrite
  • A modular architecture built to grow with the business as new features are added
