Votrechien - we are exclusively online on several marketplaces. The op mentions having to pay his invoices and invoice profitability. These are financial transactions and you should use an accounting system - whether QB or something more robust. We track our orders by marketplace and state/country, items, etc. Our invoices are entered, we have reminders to pay items, payment terms built in, etc. This is standard stuff.
