The result is mapped into the Bright-facing BrightInvoice model.

SonWin is a BALANCE-FORWARD ledger: payments are not matched per-invoice.
The "remaining amount" and the payment status are both derived from the running account balance (løbende saldo) as of each invoice line, computed in SQL.

DEV info

When running on local machine bypassing the Swagger UI:

Visibility/filtering is configuration-driven. Each filter toggle is resolved as "local appsettings config wins, otherwise defer to the company's BCHEC flag" (Sonlinc.BCHED, cached in memory).

The SQL is assembled from pure-SQL fragments so only the active clauses appear in the executed statement.

...

The endpoint returns a JSON array of invoice objects (no wrapper). Each object contains a nested `Info` array of supplementary key/value (or title/value) entries.

INVOICE STATUS LOGIC (MapInvoiceStatus, first match wins):

1. KORTSTATUS = 99 InvoiceStatus derivation (MapInvoiceStatus), in order:
1. KORTSTATUS == 99 -> "cancelled"
2. TotalAmount (KR) < 0 -> "credited"
3. SettlementDate (UDLIGNDATO) set -> "paid" (regardless of PaidAmount)
4. PaidAmount >= TotalAmount -> "paid"
5. DueDate < today (and not fully paid)-> "overdue"
6. PaidAmount > 0 -> "partly_paid"
7. otherwise -> "unpaidcancelled"
(collection / reminder / deferred_* / investigation / paid_out are never returned — TODO.)

PaidAmount source: OUTER APPLY over Sonlinc.AKOND where TARIFART='PBSI' for the same INSTNR+FORBNR+UDEBNR+REGNINGNR+FIRMANR; SUM(KR*ANTAL)*-1

(PBSI rows are negative), ISNULL(...,0). Not exposed as its own response field — only feeds RemainingAmount and the status derivation.

confirmed cancelled)
2. TotalAmount (KR) < 0 -> "credited" (credit note)
3. UDLIGNDATO set OR running saldo <= 0 -> "paid" (account square through this line; balance-forward)
4. DueDate (FORFDATO) in the past -> "overdue"
5. otherwise -> "unpaid"
('partly_paid' is intentionally never produced.)

PERIOD LOGIC (MapPeriod): month span = (EndDate - StartDate) in whole months;

2→"2month"
3→"3month"
6→"6month"
12→"12month"
anything else (incl. missing dates or 1-month) -> "1month".

- AfregnType (AKOND.AFREGNTYPE) used only by ServiceId (KØL -> cooling)
- KortStatus (AKOND.KORTSTATUS) used only by status (== 99 -> cancelled)
- KortType (AKOND.KORTTYPE) selected, currently unused in mapping
- SettlementDate (AKOND.UDLIGNDATO) used only by status
- CollectiveBillNr (AKOND.SAMLREGNINGNR) selected; also used as a WHERE filter
- HasPdf (EXISTS check) used only by InvoiceType
- PaidAmount (PBSI sum) used by RemainingAmount + status
