Having your invoice numbers different from the default number sequence is needed in some countries, where the number must match an existing sequence.
Note: The following guide is relevant if you are using the template designs that are provided within the Order Printer Pro app.
It is possible to have a custom invoice number sequence in your documents through a small change to the template code. The way to do it would be to find this code in your template:
{{ name }}
And replace it with:
#{{ order_number | minus: xxxx }}
Note: You must replace the xxxx in the above code with the correct number to start your sequence.
You can also change
{{ name }}
to
#{{ order_number | plus: xxxx }}
If what you need instead is to increase your order number.
The order number starts at 1 for your first Shopify order, so you need to do the math and adjust the number to get the correct number series based on your needs.
