CLIENT
About the client

KakeMart — a leading domestic name driving B2B distribution.

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.

CHALLENGE
Design challenges to solve

The four structural requirements demanded of B2B ordering.

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.

Move phone and fax ordering online
With phone & paper, mishearing & transcription errors happen easily.
Automate credit-payment billing
When month-end invoicing is manual, closing work piles up.
Make the latest stock and prices shareable
When price lists are stale, inquiries & mix-ups increase.
Make order and shipping status visible
When progress is invisible, handling inquiries eats up time.

ARCHITECTURE
The architecture we built together

Turning B2B trade into an unstoppable platform across four domains.

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.
