Subtracting Cost of item from Sales total after Invoice was paid
Hi there, I'm a brand new quickbooks user converting my first business year of manual bookkeeping to quickbooks and made a mistake on the first sale. I'm using the EasyStart version which does not include inventory tracking. About 10% of my business is refurbishing items we purchase for re sale, 90% is items customers send to us for refurbishing. Our first sale was for 2 items we purchased, refurbished and sold. At the time of invoicing the customer I forgot to figure out where to put the cost of each item so it gets subtracted from our sales profit and the original purchase prices added to expenses. I can't figure out how to make this adjustment now after the customer has paid the invoice. I've tried creating a COGS account setup as an inventory type account inputting the items and costs manually but nothing I seem to do makes any adjustments to our overall sales amount or even appear in the COGS account we created, the account balance stays at 0.00. Any help to get this mistake corrected and a solution for future COGS sales so the cost is always going to expenses and the remaining to sales profit is appreciated!
