How does “Building a run” work on the Payment Runs page?

Tick bills into a named draft run; the panel beside the table carries the running total and a subtotal per company, because each company pays from its own account. A bill may be paid in part — the rest stays outstanding and returns to the list once the run is settled. Where the run needs approval (over the limit, or every run, as the company's rule says) it waits in the queue at the top of Build run for a second person; the builder never approves their own. Generate the bank file in the layout set for the paying account, upload it at the bank, and when the bank has paid press Mark as paid: Saral records the payment on each bill in Xero from the account the file debited, dated the file's payment date. A bill paid another way — a card, a journal, an intercompany loan — is marked paid from the bills table without a file. Remittance advices are drafted for each supplier when the run is marked paid and sent when a person presses Send all, unless your account made them automatic or switched them off. A bill BillScan records as paid from another company's account — a group card paying a sister company's bill — needs nothing here: it is put in a run of its own, marked paid from that account, and both intercompany entries go to Xero; until then it is listed under Paid by another company on Build run, and one that could not be carried says why, with Retry.
