Not the same as the $12,000 offline license. The Calculator Pass is browser-only online access. The offline license is a downloadable, phone-portable copy of the calculator meant for enterprise procurement. Different buyer, different SKU.
“You are purchasing full-catalog online access for the email you sign in with. Online only; no download.”
Listed prices exclude any applicable sales tax; Stripe adds the correct state and local rate at checkout where required by law. Enterprise B2B orders (RIDDLE contracts, QBeam SKUs) settle by wire under a signed PO and are quoted net of tax unless a resale certificate is on file.
