Smart Vending Platform Development

WebOsmotic built the full digital platform behind Mabel, a smart retail brand that sells chef-made fresh food from smart machines. A customer orders and pays in the app, then collects on the way past. The build covers backend development, cloud engineering, DevOps, and mobile app development, from the mobile app to payments, machine link, and cloud setup.

Mabel sells chef-made fresh food from smart machines. A customer orders and pays in the app, then collects on the way past. Behind that simple experience sits a complex system, and WebOsmotic built all of it, from the mobile app to the backend, payments, machine link, and cloud setup.
The whole model had to be proven on a single machine before it could scale, and the worst outcome in click-and-collect is charging for an order that cannot be released. WebOsmotic engineered the platform to make payment and machine confirmation settle as one decision, ordering, payment, and stock working together as a single reliable system, ready for the rest of the business to build on.

Challenges in Building a Smart Vending and Click-and-Collect Platform

Deliverables — Smart Vending Platform Features Built for Mabel

Results — Impact of the Mabel Smart Vending Platform

Payment and collection consistency: a customer could pay without being able to collect, so payment confirmation and machine availability had to be treated as a single transaction decision.
Real-time inventory synchronisation: fresh stock changed throughout the day, with app orders, walk-up sales, and restocking all affecting the same inventory in real time.
Automated expiry-based pricing: food value decreases as expiry approaches, requiring prices to automatically step down and synchronise with the machine.
Hardware simulation before deployment: with no physical hardware available during development, every stage of the workflow needed a realistic device simulator to respond like the production machine.
Concurrent inventory allocation: multiple customers could attempt to purchase the same final unit, requiring transactional controls to prevent two orders from claiming the same stock while keeping machine interactions responsive.

Working machine simulator: a simulator that reproduces the machine’s side of the exchange, allowing the complete ordering and collection flow to be built and tested before any physical device was connected.
Payment and machine confirmation as one decision: an order reaches the charged state only after both payment and machine confirmation succeed, with the capture implemented in one controlled code path that can only be reached once.
Two locks for two problems: one lock determines which order gets the final unit of stock, while another prevents the same order from being processed twice when multiple backend instances run concurrently.
Automatic expiry pricing: prices decrease automatically as food approaches expiry, with the app menu and machine following the same pricing rules.
Scalable, observable cloud platform: the platform is designed to run across multiple servers, with UK data residency, failure alerts routed to a person, and charged-but-undelivered orders logged for review.

Proved that one machine could work, creating a platform the rest of the business can build on, with ordering, payment, and inventory working as one system.
WebOsmotic delivered a tested platform in four weeks, before any physical machine was connected, by removing the hardware dependency from development.
Protected money and stock at every step: customers are never charged twice, abandoned checkouts do not hold inventory, failed collections trigger refunds, and the machine’s own stock report takes precedence when discrepancies occur.
Built for UK data residency and multi-server scalability from day one, allowing the platform to grow as more machines come online without requiring a rebuild.
Turned a complex, multi-system operation into a production-ready, scalable platform that provides a strong foundation for the rest of the business.

Mabel set out to prove one machine could work. What came out of it is a platform the rest of the business can build on, where ordering, payment, and stock already work as one system. Removing the hardware dependency from development let WebOsmotic deliver a tested platform in four weeks, before a physical machine was connected. The engineering decisions protect money and stock at every step: a customer is never charged twice, a failed collection returns the money, and the machine’s own stock report wins when there is a disagreement. Built for UK data residency and multi-server scale from day one, the platform grows without a rebuild as more machines come online. This case study shows what smart vending platform development looks like end to end, from discovery to a production-ready, scalable platform.

How much does it cost to build a smart vending or click-and-collect platform like Mabel?

A smart vending platform with a mobile app, payment and machine confirmation logic, and cloud infrastructure typically costs between $35,000 and $95,000, depending on the number of machines and integrations.

How long does it take to build a click-and-collect platform without hardware in hand?

A first tested platform can take as little as 4 weeks when a machine simulator replaces physical hardware during development, with a full production rollout typically taking 3 to 6 months.

Can the platform scale to support more machines without a rebuild?

Yes. The cloud architecture is built to run across multiple servers and support additional machines as the business grows, without requiring a new platform.

Does the platform handle stock conflicts when multiple customers order the same item?

Yes. Locking logic settles which order gets the last unit in stock and prevents the same order from being processed twice.
