It is not a payroll service or a payment processor; it only estimates.
Every build runs the engine against the CRA's published payroll deduction tables (T4032, claim code 1, bi-weekly, 13 jurisdictions) and Revenu Québec's source-deduction table: 10,260 rows. A build that disagrees with them does not deploy.
