How do you close a financial year & balance forward to the next year?

I can show you how you can close your books, darylbenecke-gma.

You close your books to prevent changes. This locks your books so no one can edit your accounting data before the closing date. Here's how: 

1. Click the Gear icon at the upper-right and select Account and settings.
2. From the Advanced menu, click Accounting.
3. Select the preferred financial year, accounting method. 
4. Toggle to close the books and enter the Closing date and select the desired preference. 
5. Select the default tax rate selection and then Save and then Done.
