Pay several bills with one payment

When one bank payment covered several bills (a batched supplier payment, a Stripe sweep, one cheque for two invoices), match them all to that single bank transaction:

1. Go to Ledger › Expenses (the Bills and Receipts list).
2. On an approved bill, click its purple Match pill.
3. Pick a bank transaction whose amount is larger than that bill. Because it overshoots one bill, the picker flips to the combine pane.
4. Tick the other bills this payment covered. A running Selected total: $X of $Y shows how much of the transaction you've allocated.
5. Click Match N invoices to this transaction.

TALISK_HQ records a separate payment against each bill and closes them. If the bills don't add up to exactly the transaction amount, the last bill takes a partial allocation: it stays open for the rest.

If you select more bills than the payment covers

The payment is allocated to the bills in the order you ticked them, capped at what each bill still owes. If it runs out before the last bill, that bill would be paid nothing, so TALISK_HQ refuses the whole match instead of linking a bill you didn't actually pay. The button tells you which bill is the problem ("Tail Co would be paid $0 — deselect it"); untick it and match it separately.

A bill that gets a small partial allocation is fine: that one is a real payment and stays open for the remainder. Only $0 is refused.

A credit note can't be combined with bills you are paying

A payment going out settles bills; a vendor credit note is settled by the refund coming in. So the combine pane lists only what the chosen transaction can settle: against a payment going out, your credit notes are left off the list. Match a credit note to the refund deposit instead. One refund that covers several credit notes works the same way as one payment covering several bills: start from a credit note's Match pill, pick the larger refund, and tick the other credit notes it covered. If a combined match that includes one reaches TALISK_HQ some other way, it is refused and names the credit note.

Preconditions: each bill must be Approved first (an unapproved bill has no Accounts Payable to relieve), the bank transaction must be unmatched, every bill must be in CAD (a foreign-currency bill is paid on its own, in one payment or in several: see "Pay a foreign-currency bill in instalments from your CAD account") and every selected bill must receive at least a cent of the payment.
