DELIVERED SCOPE
The scope that was actually built.
- 01Mobile transaction flow
- 02Catalog and order structure
- 03Reporting and offline-first direction
INTERFACE EVIDENCE / FROM THE WORKING PRODUCT
One interface at three levels: system, flow, and control detail.
01 / THE PROBLEM
A useful system starts with the right problem.
Small businesses need fast transaction tools, yet complex products often create more work and assume a permanently stable connection.
A POS experience focused on essential cashier tasks, a clear catalog structure, and an offline-first foundation for daily operations.
02 / SYSTEM FLOW
One continuous flow. No isolated features.
01Choose product→
02Create order→
03Confirm payment→
04Daily summary
03 / PRODUCT DECISIONS
The decisions that shaped the product.
CORE CONSTRAINTKeeping daily operations simple while creating a data foundation that can grow.
Offline as a baseline
Core operations are not designed around the assumption of a perfect connection.
Summary, not noise
The dashboard surfaces essential operating signals without flooding the user with data.
04 / OPERATIONAL VALUE
What the product brings into daily operations.
- 01The transaction flow is shorter and clearer
- 02Product and sales data become more structured
- 03Product development follows real operating needs
