Welcome to the Community. It's essential to correctly record your sales tax to keep your books balanced. QuickBooks Online is a great program that offers the ability to track your sales tax to make sure that the correct amount is reported to the CRA. I'd be glad to point you in the right direction to record daily sales with sales taxes as separate entry.
To record your sales with sales taxes as separate entries, I encourage you to use the journal entries. The journal entry will allow you to choose your sales and sales tax accounts. If you're unsure of which accounts to use for journal entry, I recommend contacting an accountant. They'll be able to point you in the right direction to record your journal entry to keep your books balanced. If you don't have an accountant, we can help you locate a ProAdvisor in your local area.
Let me know if you have any questions, I'll be happy to help.
