ÇAK: a discount platform that reduces food waste
A platform where bakeries, greengrocers, restaurants and markets list the products they couldn’t sell during the day at a discount, and users buy them with an in-app wallet and pick them up at the store. It consists of a customer app, a business app and a website.

Products thrown away every day
A large share of the products left at the end of the day in bakeries, greengrocers and restaurants is thrown away unsold. For the business, that means lost products and lost revenue.
For users, there is no easy way to find quality products at a good price. Announcing discounts is also time-consuming and expensive for small businesses.
What we built
ÇAK (customer app)
Explore and map
Deals are shown in “Biggest discounts”, “Almost gone” and “Recommended for you” lists and on a map.
Wallet
Users top up their wallet securely with iyzico and buy with a single tap.
Delivery code
Products are picked up within the time window set by the business by giving a delivery code.
Cancellation and refund
Orders can be cancelled before pickup, and the amount goes back to the wallet.
Ratings and invites
Users rate the business after each pickup and can suggest or invite businesses they want to see.
ÇAK İşletme (business app)
Three-step application
The business enters its details and submits its documents, and the team reviews the application.
Adding products
The business decides which products to sell, how many, at what time and at what discount. There are three discount types: same-day products, promotions and products with damaged packaging.
Happy hour
Time-limited discounts help balance customer traffic.
Sales notifications
Each sale triggers a push notification, email or SMS.
Wallet and payouts
Revenue from completed orders is tracked in the business wallet and paid out on the dates in the agreement.
ÇAK Web
Website
Separate pages for users and businesses, FAQs, the membership agreement and a form to suggest businesses.
Challenges and solutions
Challenge
Secure payment without cash at pickup.
Solution
A wallet balance through iyzico; payment is held until both sides confirm, then transferred to the business.
Challenge
Keeping business quality high.
Solution
An application process with document review, plus user ratings after every pickup.
Challenge
Crowds and waiting at the store.
Solution
Businesses set the pickup windows, and happy hour steers customers to quieter times.
