Meet Vendplex: B2B ordering, finally simple.
Most wholesale orders still arrive by phone, WhatsApp and spreadsheets, and every one of them gets re-typed. Vendplex puts your sales reps, your customers and your back office on one mobile-first platform, with group and tier pricing, delivery route planning and real-time ERP sync.
- — One app for customers, sales teams and admins
- — Customer-specific and volume-based pricing
- — Real-time ERP integration, no re-keying
Customers
A catalog that feels like B2C, with wholesale rules underneath.
Sales team
Live stock, dues and order status while they are with the buyer.
Back office
Pricing, routes and ERP postings without a morning of re-entry.

Proof, not promises
Stores, apps and platforms we have engineered for real traffic and real operations.

Why YUJ
Why teams choose YUJ
AI-native delivery

We build our own product
Vendplex means we know what it takes to run software in production, not just hand it over.

Flexible engagement
Fixed-scope projects, dedicated teams or monthly growth retainers, whichever fits your stage.
One accountable partner
Store, WhatsApp, AI and integrations from one team, so nothing falls between vendors.
