Hi there, charles-bokamoso.

Let me help with your question about setting up terms in QBO. I'd also like to ask if the statement date similar to the invoice date? If so, you can use the Net 30 terms. Here's how:

1. Go to the + New button and select Invoice.
2. Click the drop-down list for Terms and select Net 30.
3. Enter all other details of the invoice. 
4. Click Save or Save and send. 

If it's different from the invoice date, we're unable to set up other terms based on the statement date. QBO will use the due date or terms assigned based on the invoice date. 

I'd also like to share a few more guide articles and reference just in case you might need them in your future tasks:

• Due Date and Invoice Date Do Not Match When Using Due on Receipt Term
• Report of Invoices That Are Due on a Specific Day
