Credit notes, duplicate detection and deleting invoices

Getting money back from a supplier — for a returned item or a billing correction — had no place to go in SNDQ. Register a credit note against a purchase invoice, whether it arrives through Peppol or you enter it manually, and apply it to reduce what's still owed. A purchase invoice's detail page now also includes a timeline of everything that's happened to it.

Catching a duplicate invoice — the same one sent twice, or entered manually after already arriving through Peppol — meant noticing it yourself. SNDQ now checks automatically across however the invoice arrived (Peppol, email, or manual upload), flagging a likely duplicate with a confidence level based on the invoice number, supplier, amount and date. Checks are scoped to one building, so invoices from different buildings are never flagged against each other.

A purchase invoice can now be deleted from its detail page — as long as it hasn't been paid, allocated, or has a payment already in progress. Deleting one also cleans up its accounting entries, and unlinks it from any Peppol invoice it came from, so that invoice can be matched again later if needed.

Purchase invoice creation launched in December, but assigning a cost still worked the way it does for Building Manager — by ledger account. It now works properly here too: assign a cost using cost categories instead, either to a single building or split across several, matching how these workspaces are actually structured.

Mark a supplier as paid by direct debit, and every purchase invoice from that supplier is flagged the same way automatically — though it can still be turned off for a specific invoice if needed. Once marked, the option to create a manual payment for that invoice is hidden, since the bank handles it directly.

Most costs are split between owners right away, using a distribution key. A purchase invoice can now be marked as a deferred cost — held back from that split, so it isn't allocated until you decide it should be.
