# BayStacker > BayStacker is diagnosis-first transmission shop management software and shop operating system: > the complaint, the decoded VIN and the first finding become one diagnosis case, Analysis A > returns a ranked hypothesis with the next test and the rework risk, and the work order, > R&R and bench labor, teardown inspection findings, unit build sheets, torque converter and valve body > core tracking, QC verification gate, warranty rework ledger and invoice read from that same record. BayStacker is sold per location per month, in two editions ($149 USD Intelligence and $499 USD Full OS), with a 7-day free trial (a card is required when the trial starts and first charged when it ends) and 1,000 analysis runs a month. It is built for transmission shops, powertrain rebuild shops, fleet operations and general repair shops with a transmission bay; the people who use it are service writers, diagnosticians, builders, R&R technicians, parts staff, QC inspectors and owners. It has no labor guide, no integrated supplier parts ordering and no two-way texting, it does not process card payments (payments are recorded on the invoice), and it has no direct import from Tekmetric, Shopmonkey or any other system: history comes in as a CSV file after a dry run.
