Edge cases, tiny single-chair clinic vs DSO with 50+ locations, does the same Magento store fit both?

Yes, if you architect customer groups + B2B Companies correctly, one Magento store handles both extremes cleanly. The two ends:

Tiny single-chair clinic (the long tail):

• Self-serve signup, no credit check, card-on-file or first-time bank ACH
• Auto-ship subscriptions for high-velocity consumables (gloves, masks, pouches), the highest-leverage move for retention
• One buyer (the dentist or the office manager), one ship-to address
• Simple product search + reorder-from-history UX
• Optional Net-30 after 90 days of card-paid orders + a soft credit check

DSO with 50+ clinics (the head):

• Corporate account at the DSO HQ, 50+ clinic ship-to addresses under it
• Multi-buyer roles: clinic office managers can request, regional managers approve up to $5k, DSO procurement director approves > $5k
• Location-level reporting (which clinic ordered what, when, how much)
• Contract pricing per category, negotiated annually, applied automatically
• Net-45 or Net-60 on a single AR account, ERP-synced (Sage Intacct, NetSuite, Microsoft Dynamics)
• Required PO number per order
• Practice-management API integration that pulls used-product lists from each clinic’s Dentrix / Eaglesoft / Open Dental / Curve / Carestack instance
• EDI 850/855/856/810 with the DSO’s procurement system if they have one
• BAA signed, HIPAA audit-trail enforced, 21 CFR Part 11 electronic signatures if they have a research arm

The architecture: customer-group-based visibility + Magento B2B Companies (Adobe Commerce) or Aheadworks Company Accounts + Amasty B2B Suite (Open Source). Same SKU pool, shared inventory, totally segregated pricing + payment-terms + reporting visibility per account type. Magento is the only mid-market platform that handles both extremes without forcing a split-stack architecture.
