B2B e-commerce and wholesale

Industry

B2B commerce that dealers want to order on. Platforms renewed, onboarding on time.

Wholesale runs on dealers who order the same things fast and expect their own terms. I own the product and the technical decisions behind B2B ordering platforms, from UX and specifications to the systems they connect to.

The challenge

01

Your dealers shop like consumers at home. Your platform still makes them call.

When ordering is slow, dealers phone, email or order elsewhere, and your team re-types orders by hand. Every wrong price, stock figure or customer term costs margin and trust. AI can take over product data, quotes and order questions, but only on a platform that stays exact.

Questions

FAQ

Can you onboard a new customer on a fixed date?

Yes. I scope the custom requirements and backend work so the date holds, and keep the team on one plan.

Yes. Integrations are part of the architecture, decided and written down before the build.

Where do agents help in wholesale?

In product data, quoting and order questions, inside clear rules on prices and customer terms.
