Thanks for joining the thread, @DanaM12. Yes, discounting your invoices will lower your monthly sales.

It's important to note that offering discounts to your customers will affect your monthly sales figures, as a portion of the sales will be categorized as discounts given and recorded in the Discounts Given income account. 

If you want to avoid reducing your sales figures, you may consider providing credits to your customers instead of discounts. However, I strongly recommend consulting with an accountant to ensure this approach aligns with your business structure.

Additionally, running a detailed financial report provides a comprehensive overview of your business' status. 

Please return to this thread if you have other concerns with your discounts. We'll be here to help you in any way we can.
