The line items to confirm in writing
Work through each of these with White Label Rx and get the answer in your quote, not in conversation. Shipping and handling: is it per order, per box, flat, or free above a threshold, and does cold-chain add cost? Payment processing: is a card or ACH fee passed to you on each transaction? Platform or software fee: is there a recurring access charge separate from drug cost? Account minimums: is there a minimum order or monthly volume, and what happens if you miss it? Rush or expedited charges: what triggers them? Returns, cancellations, and reships: who absorbs the cost when an order is wrong or rejected?
Once you have those answers, recompute your per-vial landed cost by spreading every applicable fee across the vials in a typical order. The headline drug rate almost always looks better than the all-in number; your patient pricing and margin model should be built on the all-in figure. If a fee is variable, ask for the typical case so you can plan, not just the best case.
