Multi-vendor payouts

Always-on rule for multi-vendor-payouts  ·  Source

• Put a vendor_id on every sellable line. Do not pay a line that has no vendor.
• Record commission as ledger entries. Do not rewrite the line price to remove the fee.
• Write payable entries only after the shopper's payment is confirmed. Authorization is not a payout.
• Hold entries until the stored refund window or delivery rule. Upcoming balance is not the payout sum.
• Stamp payout_id on entries in the same transaction that creates the batch. Retry the provider with the batch idempotency key.
• A refund adds reversing entries. Do not delete the original sale entries.
• Keep tax and shipping in their own entries, credited to the party the marketplace named.
• Sum the ledger at payout time. Do not also sum the original order totals.
• Record who is merchant of record. Do not assume it is the vendor.
