Without stopping ordering, into the next decade.

MartCube is a BtoB e-commerce platform supporting corporate ordering. It unifies quotations, credit sales and bulk ordering into one, connecting business partners, purchasing staff and operations.

A business transformation story: migrating a legacy EC that 'went down in peak season, scattered operations across Excel, and left price management to individuals' onto a cloud platform through a 10-month, zero-downtime renewal.

CHALLENGE

The business challenges faced

Four business challenges holding back growth.

None of these were technical issues, but management challenges tied directly to sales opportunities, operational efficiency and continued trade. A renewal that solved them without stopping the service was needed.

The ordering EC went down in peak season

At month-end when access spiked, the old platform went down under heavy load, and orders were lost.

Quotations and ordering scattered in Excel

Quotations and bulk ordering were run over email and Excel, increasing transcription errors and manual work.

Per-company pricing managed by individuals

Pricing for each partner was managed by hand by individual staff, creating handover and accuracy problems.

Security upkeep was difficult

With the aging platform, vulnerability response could not keep up, posing compliance risks.

TRANSFORMATION

The transformation achieved together

Without stopping the business, into the next decade across four domains.

Without ever stopping ordering, we migrated from the old EC to a new cloud platform. Storefront and admin were renewed as one, delivering all four domains at once.
