Mobile appE-commerce & marketplacesOriginal by Koçtaş
Koçtaş is one of Turkey's leading DIY and home improvement chains, comparable to B&Q, Home Depot or OBI. In stores like this, customers usually shop for a project: a bathroom renovation, painting, garden landscaping. The app makes the whole job easier by bringing together tools that calculate the right quantities, store stock, delivery of bulky items and installation services. Being able to offer services as well as products is the foundation of loyalty.
To build something similar you need a technical catalogue of tens of thousands of items, area and quantity calculators, bulky delivery and click-and-collect options, installation and tradesperson booking, and store stock integration. In addition to the customer app and web store, a job tracking screen for service teams and a panel for managing the catalogue and services should be built.

The hard parts
Large technical catalogue
Many products have different units of measure and attributes; with poor data quality, search and filters become useless.
Delivery cost calculation
For heavy and bulky items, pricing that does not account for zone, floor and vehicle type leads to losses.
Service quality management
Installation is often delivered by subcontracted crews; job tracking, ratings and complaint handling must be well designed.
Business model
Revenue comes mainly from product sales; installation, assembly and delivery services bring extra revenue and high customer satisfaction. Trade accounts for tradespeople and contractors, bulk purchase discounts and payment-on-terms options attract the professional segment. Promotion fees charged to brands can be an additional line.

Choosing a company to build an app like Koçtaş
Most people searching “build an app like koctas” are really looking for a reliable app development company. When comparing quotes, check four things:
- Can you try similar products they have shipped, in the stores or live?
- Are the source code, design files, servers and store accounts transferred to you by contract?
- Do they show a working demo every two weeks, with written scope and acceptance criteria?
- Are maintenance, scaling and GDPR/security costs written into the quote?
Copyright and trademarks
A business model and features are generally not protected on their own, but the Koçtaş name, logo, interface design, content and source code are. That is why we build a product with similar functionality but your own brand, design and code. This is not legal advice; we recommend a trademark search before launch.
