Sequential numbers for invoices, exclude contact form

[Andre_B]

I’m using 3 forms on my site to collect customer orders and invoices. To comply with regulations by financial institutions in my country invoices need to have sequential numbers.

I’m using the entry ID of GF to create the invoice number and publish it in the customers notifications.
The problem with this procedure is that the entry ID sequence will count every form submission, in my case one contact form as well.
Is there any way to assign a different numbers pool to the contact form? Or any other solution?
I’d hate to install another form plugin for the contact form.

This is possible with our Unique ID plugin and a simple snippet for indicating which Unique ID fields should share the same sequence (e.g., pool).

Any questions, let me know!

Thanks for the response but this is another paid subscription plugin. Not an option for me at this price point and the model itself.
