Cost + timeline + your credentials, what does a Magento office-supplies build actually look like?

Realistic ranges for a mid-market office-supply dealer ($1M, $20M GMV) migrating to or building on Magento:

• Audit: $499 fixed-fee, ~20h @ $25/hr, 5 business days. Catalog SKU review, current contract pricing rules, punchout provider gap, GSA/AbilityOne metadata completeness, sustainability claim audit. Written 12-18 page report.
• Build: $4,999 fixed-fee, ~200h @ $25/hr, 6 weeks. Catalog import + tiered pricing rules + Coupa cXML punchout + multi-location address book + Net-30 via Apruve + subscription auto-ship for top 50 SKUs.
• Custom enterprise: typically $50k, $180k for a full procurement portal with 5+ punchout providers, GSA Schedule daily price-file sync, AbilityOne flag routing, multi-region delivery, full sustainability claim audit. Quote in 24 hours.
• Hosting: $400, $2,000/mo on Cloudways / Hyperlex / dedicated. Multi-location dealers with overnight delivery commitments need over-provisioned + CDN.
• Ongoing: $1.5k, $5k/mo retainer for continuous procurement-platform integrations (each new enterprise punchout customer = 2-4 weeks of integration work).

My credentials: Adobe-Certified Magento + Hyvä developer, 8+ years building B2B procurement stores for office-supply dealers, MRO suppliers, and industrial distributors competing against Staples Business Advantage, ODP Business Solutions, Quill, Amazon Business, and Uline. The patterns repeat across categories, contract tiered pricing, cXML / OCI punchout, Net-30, multi-location, sustainability flags, and Magento + Hyvä handles all of them on one instance.
