INVOICING
Invoices grouped per buyer with hammer, premium, and tax computed — sent, tracked, and remindable.
After the sale, every buyer owes you exactly one thing: a correct invoice, promptly. SoldSheet groups each buyer's lots onto one invoice, computes premium and tax from the auction's settings, and sends it — then tracks who has paid and nudges who hasn't.
Checks haven't died in this industry, so invoices work without payments connected: record a check or cash payment against any invoice and the books stay right.
