I've read all your replies on this thread, @rgonzalez21. I have solution about your voiding concern.  

I'll share some information about voiding bills and checks in the current period without affecting prior years. This way, your books will stay accurate at all times. 

Voiding current checks will not affect the previous years, whether reconciled or not. They will only affect prior years if the bill/bill payment you'll want to create/void is dated back to the previous years. That said, you can directly void or delete them. 

Do the following: 

1. Go to the Vendors tab and select Vendor Center. 
2. Open the appropriate bills and checks you want to void one at a time. 
3. Click the Delete drop-down, then pick Void. You'll see a VOID in the Memo field. 

To void multiple bills and bill payment check, you can follow the instructions outlined by my peer Giovan_G above.
