KakeMart is a B2B ordering platform connecting restaurants and retailers with suppliers. Everything from product search and ordering to credit-payment invoicing and LINE notifications is completed on a single platform.
Ordering experience, credit-payment billing, order & shipping management, LINE integration ─ a new-platform launch story of building the functions B2B trade needs, from scratch in-house in seven months, across three screens for stores, suppliers and operators.
KakeMart runs a B2B wholesale ordering business that connects restaurants and retailers with suppliers. It operates a platform where stores can source the goods they need — produce, meat, dairy, seasonings and more — from multiple suppliers in one place.
To move ordering — once centered on phone, fax and handwriting — online, all the way through credit-payment billing, we launched a dedicated platform from scratch.
None of these were mere feature additions — each was a business requirement tied directly to the workload of stores and suppliers, transaction accuracy, and cash flow. A greenfield build required a design that could satisfy them all at once.
We built four domains from scratch, in-house — ordering experience, credit-payment billing, order & shipping management, and LINE integration — by combining a Laravel API, three screens, and automatic document generation. It is the launch of a new ordering platform that connects stores and suppliers online, without relying on phone or fax.

This platform delivers not technical metrics but continuous business outcomes — ordering efficiency, transaction accuracy, and a lighter closing-work load.
