When upgrading to Silver or Gold pays off
Model break-even on the $500/mo jump from Bronze to Silver against fulfillment savings per shipment. If volume-based pricing saves $3 per order and you ship 200 orders per month, that is $600 in logistics savings against $500 in added SaaS — before counting enhanced analytics and full white-label customization. Below that volume, you may be paying for a feature you do not yet use.
Gold adds priority allocation and API access on top of Silver's volume fulfillment. High-growth DTC brands scaling patient portal orders may value allocation during supply constraints; prescriber-side clinics batching refills may care more about per-vial drug cost than portal allocation. Match tier to the bottleneck you actually have.
