Why patient-portal stacks often validate late
Patient-facing checkout optimizes for conversion speed — patients complete branded transactions quickly. Deep prescriber-side validation across a multi-patient staff cart is a different engineering priority. RxFul may perform checks in fulfillment pipelines, but if those checks are not visible before payment, staff discover problems after charge.
Bring three deliberate errors to an RxFul demo: malformed SIG, prescriber not licensed in the patient's state, and a SKU you know is constrained. Note whether payment is blocked or whether you learn later from the pharmacy.
