Why build your B2B wholesale portal on OpenCart?
OpenCart includes native customer group architectures and tiered price columns. We extend it into an enterprise B2B platform: customer contract pricing tiers, Quick Order bulk upload via XLSX/SKU list, PDF invoices with tax breakdown, partner account portals, and real-time ERP inventory synchronization.

FAQ
Frequently asked questions
How does a B2B portal differ from a conventional B2C web store?
B2B portals prioritize speed, repeat orders by SKU, customer-specific pricing contracts, credit limits, and official PDF invoicing over impulse buying.
Can we operate both retail and wholesale channels on a single OpenCart site?
Yes. Guests and retail consumers see standard retail prices, while authorized wholesale partners see contract pricing and bulk reorder tools.
How do wholesale buyers receive official tax invoices?
Upon checkout confirmation, the system automatically compiles an official PDF pro-forma invoice complete with tax IDs and payment bank details.
