The eAccounting /supplierinvoices LIST payload omits RemainingAmount, and
reading the absence as 0 made every migrated supplier invoice fully paid
(ElvaSmultron: 290/290 imported as paid, including two open payables).
SupplierInvoiceApi has no IsCancelled/IsBooked/IsSent either, so the shared
status derivation could never produce an open supplier invoice.
- Supplier invoices: paid = PaymentStatus in (Paid=6, PaidInBank=9); bank
in-flight states stay open; missing RemainingAmount now falls back to the
invoice total instead of a settled-looking 0; lifecycle from Status
(0=Draft, 2=Deleted) + overdue from PaymentStatus (4, 7).
- Sales invoices: paid = PaymentStatus 0 (enum: 0=Paid, 1=Unpaid, 2=Overdue)
with the old RemainingAmount check as fallback only.
- IsCreditInvoice now maps to invoiceTypeCode '381' on both sides: credit
notes have negative totals, could never satisfy 'remaining 0 && total > 0'
and fell through to 'draft', surfacing on the dashboard as overdue unsent
invoices.
- PaymentDate now feeds lastPaymentDate so paid_at is the real payment date
rather than the invoice date.
