Retail apps built for the way London shops, from Oxford Street to the last mile.

Codeeo handles ecommerce app development London retailers can run every day: iOS and Android shopping apps tied to live stock, branch collection, delivery slots and loyalty. We build for flagships on Oxford Street and Regent Street, independent labels around Shoreditch and Spitalfields, and online brands whose customers order between Tube stops, at a desk in the City or from a flat where nobody is home to sign for a parcel.

Our team of 80+ works from Dubai, Riyadh and Karachi and has delivered 200+ projects across the UAE and the US. London clients work with us remotely: discovery, design reviews and sprint demos run by video call, and every decision is written up afterwards.

What a London shopping app can include

Features shaped by how Londoners actually buy.

A London customer rarely buys in one sitting. They browse on the Overground, check a size at lunch near Tottenham Court Road, then collect on the way home from a branch closer to where they live. Many rent flats where parcels vanish from communal hallways or end up three doors down. Visitors from abroad add another layer, shopping in the West End with cards and addresses from elsewhere.

The features below follow those habits. We order them the way most London retailers prioritise, but a first release only carries what your stores, stock feed and couriers can support on launch day. Anything that depends on a system you are still replacing goes into a later phase, so the app never promises a service your team cannot deliver. For a London retailer, the usual order is stock accuracy first, then collection, then delivery promises, because each step relies on the one before it.

Explain your project
  • Live stock by branch

    A shopper in Islington can see whether the Covent Garden store holds their size before crossing town. We connect to your EPOS or stock system and set refresh rules, so an item that sold an hour ago stops showing as available. Where branches share a stockroom or move items between them daily, we show an honest estimate rather than a precise count.

    Fewer wasted trips and fewer complaints at the counter.

  • Collection from any branch

    Customers order online and pick a branch near home, work or a station they pass through. Store staff get a pick list, mark items ready and trigger a notification, and the app shows a collection code at the till. If the item is elsewhere, the app can offer a transfer to the chosen branch with a realistic ready date.

    Online orders that bring people into your shops.

  • Delivery slots by postcode

    You decide which postcode districts get same day, next day or evening windows. Since the ULEZ covers every borough and central streets carry the Congestion Charge, slot rules can match where your vans and courier partners serve efficiently. Cut-off times can differ by area, so a Zone 1 customer and a customer near the M25 each see a promise that suits their address.

    Delivery promises you can keep across a sprawling city.

  • Flat and concierge delivery

    Delivery notes, concierge desks, parcel lockers and a named neighbour are captured at checkout and passed to the courier. Where the carrier supports it, proof of delivery photos appear in the order history. Customers can update instructions after ordering until the parcel leaves the warehouse.

    Fewer lost parcels and fewer where is my order calls.

  • Offline basket underground

    Product pages, basket and wishlist stay usable when signal drops between stations. Changes sync once the phone reconnects, and the checkout waits for a confirmed connection before taking payment. Images and prices are cached sensibly, so the app does not eat into a customer's data allowance.

    Browsing on the commute turns into orders, not abandoned sessions.

  • Limited drops and queues

    Release times, a fair virtual queue or a ballot, one per customer limits and checks against automated buying. Store staff can see who secured an item for in-store collection on release day. After the drop, unclaimed reservations return to stock automatically at a time you set.

    Launches that reward real customers rather than resellers.

  • In-store appointments

    Personal shopping, tailoring fittings, alterations and beauty consultations booked at a chosen branch, with reminders and notes the staff member sees before the customer arrives. Bookings sync with staff rotas so a branch never accepts more appointments than it has people to serve. Deposits for made-to-measure work can be taken at booking where you want them.

    Shop floor time booked by people ready to buy.

  • Visitors from abroad

    International addresses, shipping rules by destination and clear duty information at checkout for tourists who want to send purchases home rather than fill a suitcase. Size guides can show UK and European sizing side by side for shoppers who think in different measurements. Order confirmations explain clearly that import charges in the destination country may apply.

    West End visitors keep buying after they fly home.

  • Loyalty scanned at the till

    A digital membership card that your EPOS reads, with points and rewards shared between the app, the website and every branch. Tiers, birthday rewards and member-only previews can all be configured by your marketing team. Members who rarely visit a store still collect points on every app order, and lapsed members can be won back with a targeted reward rather than a blanket discount email.

    One customer record, wherever they spend.

  • Merchandising and store console

    Your head office team edits banners, collections and push campaigns, while branch managers handle collection orders and appointments from a tablet behind the counter. Roles keep head office, branch and warehouse permissions separate. Branch managers also see their own collection queue and the customers booked in that day, without access to the wider company figures.

    Trading changes go live without waiting for a developer.

Who this is for

Four kinds of London retailer we build for.

London retail covers department-store scale flagships, a few dozen shops strung along the Northern line, and labels that started on Instagram and now rent a unit on Carnaby Street. Each needs a different first release. Picking the right starting point usually matters more than the length of the feature list. We look at where your sales come from today, which stores carry the most collection potential and how your customers already talk to you, then shape the first version around that evidence.

01

Chains with branches across several boroughs

With stores in Kensington, Clapham and Canary Wharf, your biggest wins tend to be branch stock, collection and loyalty that works at every till. We start there, link the app to your stock and EPOS data, and give branch managers a simple console. Delivery slots by postcode follow once collection volumes show where demand sits. Later phases often add appointments for services such as alterations, which keeps footfall in branches that sit away from the main shopping streets. Branch teams usually adopt the tools faster when the first release asks little extra of them.

Collection often outperforms home delivery for chains in inner London.

02

Independent labels in East London

A designer or concept store around Shoreditch, Spitalfields or Hackney usually sells small runs and relies on a loyal following. The app becomes the place for drops, early access for members and story-led product pages. We keep the admin simple enough for a small team to run alongside the shop. Push notifications are kept rare and relevant, because a following built on trust tends to switch them off quickly when they feel like advertising. Members can be offered first look access the evening before a public release, which rewards the customers who supported you from the start.

Small teams need fewer screens, not fewer features.

03

Online brands opening a showroom or pop-up

When an online-first brand takes a Soho or Coal Drops Yard space, customers expect to try items, book a fitting and then order the right size for delivery. We connect the app to the showroom so a shopper's session continues from the fitting room to the checkout. Stock in the showroom and the warehouse is shown separately, so customers know what they can take home today. Fitting notes from the showroom follow the customer into the app, so a later reorder in the right size takes seconds. Showroom bookings can also be capped to the number of fitting rooms you have.

04

Grocers, florists and fast delivery operators

If you deliver within hours across a handful of boroughs, the app needs tight slot capacity, substitutions, driver tracking and cut-off times that change with demand. We design the rider and picker tools alongside the customer app so promises match what the team can physically do. We also plan for weekend and evening peaks, when demand from flats across inner London can outstrip rider capacity within an hour. Substitution preferences are captured at checkout so pickers know what a customer will accept, and drivers can confirm handovers with a photo or code.

How a London retail app moves from first call to the app stores.

  1. 01Discovery by video callWe walk through your stores, stock feeds, couriers and trading calendar on screen, then agree the customers, features and launch window for the first version in writing. Key people from stores and operations join.
  2. 02Systems and data auditWe check what your EPOS, warehouse and ecommerce platform expose, how often stock updates and where data conflicts, before any screen is designed around it. Gaps are listed with an agreed fix for each.
  3. 03Design for one-handed useScreens are tested for a shopper holding a rail on a crowded train: large tap targets, short checkout, saved addresses and clear delivery choices. Accessibility checks follow WCAG 2.2. Prototypes are shared before build.
  4. 04Build with fortnightly demosWorking builds arrive in short sprints, shown on video call and installed on your team's phones, so feedback comes from people who know your customers. Store staff are invited to the demos where useful.
  5. 05Testing in real conditionsWeak signal, awkward postcodes, collection at a busy branch and loyalty scanned at a real till are all tested before the app reaches the stores. Fixes are retested on the same devices.
  6. 06Launch around your calendarRelease dates avoid the run up to Christmas and Boxing Day sales, giving staff time to learn the tools before the heaviest trading weeks. A support plan covers the first trading weeks.

Technology

What we build this with.

We pick the stack around what you already run: your ecommerce platform, EPOS, warehouse system and payment provider. Native or cross platform is decided by the features you need, the in-house skills you have and who will maintain the app after launch. We document every integration so your own developers or another supplier can take over without starting again.

Questions London retailers ask before commissioning an app.

It depends on how many of your systems the first release must connect to.

An app that reads from one ecommerce platform moves faster than one that also talks to EPOS in every branch, a warehouse system and a loyalty engine. We agree the first release in discovery, list each integration, and write the dates into the scope before design starts. Fixed trading moments, such as a store opening or a collection launch, are planned backwards from that date. Larger programmes are split into phases so the first version reaches customers sooner.
