How long does a Magento B2B build take?

Typical phased timelines:

• B2B Audit: 1 – 3 days — discovery + written report.
• Standard B2B Build: 8 – 10 weeks — B2B module setup, companies/roles, quote workflow, multi-tier pricing, requisition lists, 1 ERP connector, Net-30 + credit limits, sales-rep dashboard, blue-green deploy.
• Enterprise B2B: 12 – 16 weeks — everything above plus multi-region orchestration, headless GraphQL B2B, multiple ERP integrations, custom sales-rep CRM, ABM integration.

Add 2 weeks for UAT with your real B2B buyers, regression QA, and the production cutover. We work daily on staging with review access from week 2.
