F1: GetCustomerStatementAsync/GetVendorStatementAsync on IFinancialReportService;
StatementLineDto; CustomerStatementDto/VendorStatementDto; Statement action on
CustomersController + VendorsController; Statement views + PDF download via
StatementPdfHelper (QuestPDF); Statement button on Customer/Vendor Details pages.
F2: PaymentTermsParser static helper (CalculateDueDate, ParseEarlyPaymentDiscount);
EarlyPaymentDiscountPercent/Days on Invoice entity; GetCustomerPaymentTerms AJAX
endpoint on InvoicesController auto-populates Terms + due date on customer select;
early payment discount notice on Invoice Create.
F3: TaxRate entity (Name/Rate/State/IsDefault/IsActive, tenant-filtered);
IUnitOfWork.TaxRates + UnitOfWork + ApplicationDbContext; TaxRatesController
(Index/Create/Edit/Delete/ToggleActive, CompanyAdminOnly); GetTaxRateForCustomer
AJAX endpoint; Tax Rates in Settings gear menu.
Also fixes AddVendorCredits migration: VendorCreditApplications FKs changed from
CASCADE to NoAction to resolve SQL Server error 1785 (multiple cascade paths).
Migration: AddPaymentTermsAndTaxRates applied locally; 200/200 unit tests pass.
