Cost, timeline, and credentials, what does this actually cost and who’s building it?

Realistic ranges for a vet-supply distributor at $2M-$10M GMV:

• Audit: $499 fixed-fee, 5 business days, ~20h @ $25/hr. Catalog import dry-run + distributor agreement feasibility + DEA workflow + cold-chain plan + practice-management integration shortlist. Written report.
• Build: $4,999 fixed-fee, 6 weeks, ~200h @ $25/hr. Full catalog + 1 distributor drop-ship + 1 practice-mgmt API connector + DEA workflow + cold-chain rules + Rx validation. Most independent vet-supply distributors land here.
• Custom enterprise: quote in 24h, multi-week engagement. Multi-distributor orchestration (3-4 of the big four), multi-state DEA (CA, NY, FL, TX edge cases), full FDA-CVM with quarterly mock audit, equine/bovine specialty workflows, multi-region (US/UK/AU). Typical $30k-$120k depending on scope.
• Hosting: $400-$1,500/mo on Cloudways / dedicated. Vet-supply traffic is steady (no flash-sale spikes) so over-provisioning is unnecessary; cold-chain shipping APIs need outbound reliability though, so dedicated egress matters.
• Ongoing: $2k-$6k/mo retainer for distributor onboarding + new practice-mgmt connectors as your clinic customers ask + quarterly compliance audits (CSOS, cold-chain, FDA-CVM mock).
