Hi there capebretongas,
It's important that all your transactions are entered correctly so that your company's financials can be shown accurately. QuickBooks Desktop is a great software able to help you keep track of sales and expenses so you can see the profit of your business. I can point you in the right direction for assistance with the sales price.
In order to know the most effective way to make sure all your prices are updated according to rising costs, I recommend reaching out to the QuickBooks Dekstop support team. They'll be able to verify your account in order to see the way you update your costs and prices and provide the most effective way to make sure all is updated in the most effective and accurate way possible. You can reach them using the methods provided in the QuickBooks Desktop software support policies.
if you have any other questions, feel free to reach out here.
