Hi Lana Wright ,

Thanks for reaching out to us with your concern. Here’s a step that might resolve the issue:

1. Open the Payables/Receivables Ledger and select the Supplier/Customer you’re creating an invoice for.
2. Click on the Options tab.
3. In the Early Payment Terms section, ensure that both the % and pay within days options are not selected if you don't want discounts calculated for early payments.
4. Set the net amount due within the correct number of days (15 days for Net 15).
5. Click Save and Close.
6. Repeat these steps for other Suppliers/Customers if necessary.

Please make sure that you follow these steps exactly, as any deviation might cause the due dates to default to the end of the following month. If you've done this and the issue persists, it may be a good idea to check if there are any updates available for your software or to reach out to Sage 50 Canada support directly for further assistance.

If you need additional help, please let us know!

Warm Regards,
Erzsi

I wish we had this kind of control in Sage 50 Canada but I don't think you are using this version.  If you are using the US version, the moderator will move your message to the correct forum.
