Hello, Niki.

Thanks for getting back to us. I'd like to shed some light and explain the journal entry number sequencing in QuickBooks. 

Just to give some ideas on the two questions, the JE numbering sequence will keep on continuing to the next number. So, we're unable to automatically assign the same JE number for the depreciation entry. 

As for notation, you can add another set of letters on the ENTRY NO. field. Though, take note that QuickBooks will always use the numbers for sequencing. 

So, what you can do is to manually edit the ENTRY NO. field to start the sequence again and notate a particular month.  Another option for the notation is to simply use the MEMO column. Here's a sample screenshot: 

Manually editing can be achieved regardless if you're using a standard journal entry or recurring journal entries. If you opted to have QuickBooks automatically create those entries, make sure to go back to them and start editing the ENTRY NO. field. 

Though, you'll want to use the Add to my Reminders List instead and create the JEs. This way, you can review the accounts and the corresponding amounts then notate them properly and take control of the sequencing. 

We do have a bunch of video tutorials in QuickBooks Desktop. If you want to learn the ropes in recording your customer transactions or vendor bills, check them out here: Videos for QuickBooks Desktop (make sure to set QuickBooks Desktop under Videos for, then select a topic). 

Want to tackle the Reports feature in the program? I'm sure this article will come in handy: Understand reports.

I'd be happy to show you around the program if you have other things to set up (banking, customer lists, reports, etc..). Lay down the details on what you need to do and I'll gladly help you out again.
