Scenario: Over the last couple of months, Craig spent about $300 on soil for various landscaping jobs. Now that the jobs are done, he sees that he spent about $100 of it each on 3 of his customers: Red Rock Diner, Paulsen Medical Supplies, and Kookies by Kathy. How can you add these to their invoices without going into each of the old expense transactions? This is a perfect time to create a zero-dollar transaction.
