QuickBooks 2016 scheduled backup not Working

Here’s a guide to every data field you can add to a QuickBooks invoice, so you can customize it best for what your business needs!

To bring up the invoice form, click Create (+) > Invoice.

Plain invoice

Here is the simplest, most bare bones, plain cheese, QuickBooks invoice:

Invoice with the works

And here’s that same invoice, loaded up like a pizza with everything:

Invoice no.
Why use it: To enter your own transaction numbers. If you turn this off, QuickBooks automatically numbers the transactions.
Example: If you use classes to track departments/divisions, you can have retail invoices R1, R2, etc. and wholesale invoices W1, W2, etc. QuickBooks conveniently keeps the letter (based on the last invoice) and increments the number automatically for you!
How to set it: Gear > Company Settings > Sales > Custom transaction numbers.

Shipping address, Ship via, Shipping date, Tracking no., and Shipping (in subtotal)
Why use it: To track a separate shipping address, method, date, tracking number, and amount.
How to set it: Gear > Company Settings > Sales > Shipping.
Related setting: Gear > Advanced > Chart of accounts > Shipping account.

Location1
Why use it: To assign transactions to different physical locations.
Examples: Stores, sales regions, counties, properties.
How to set it: Gear > Company Settings > Company > Track locations.

Custom fields (up to three)2
Why use it: To include any other information you want to track.
Examples: Sales rep, assistant, driver, preferred delivery date, contractor’s license number.
