An invoice that has been sent is not a sale that has been completed. It is a request for money, and until the money arrives and is matched to that request, the sale is still open. Many small manufacturers and distributors treat the send button as the finish line. The goods have gone out, the tax invoice is with the buyer, and attention moves to the next order. Then a payment arrives with no reference, a buyer says they paid last week, and someone starts scrolling through chats and bank entries to work out who still owes what. Chasing by memory is where cash gets lost. What holds up better is one list of outstanding invoices, tracked against payments received. In Bloom Biz App, the invoice and payment sit in the same platform as the quotation, order and dispatch behind them. Overdue amounts are visible in that list, so your accounts staff can start from the amounts due instead of searching for them. Treat the sale as finished when the payment is matched, not when the invoice is sent.
