Hi TED GREENWALD ,

Thank you for reaching out. Have you been able to resolve this issue or are you still experiencing difficulties?

Could you please confirm if you have a payment service like Stripe or PayPal connected to your Sage 50? This is a known issue related to pending invoice payments from such services when opening a company file in single-user mode. Also, knowing the specific version of Sage 50 you're using will help in providing more accurate guidance.

If you haven't already, please try these steps:

1. Disconnect from the internet and log in to Sage 50 in single-user mode. This can be a temporary workaround.
2. Check under Setup > Settings > Receivables > Invoice Payments and ensure the "Automatically download payments when the company opens" box is unchecked.

If these steps don't resolve your issue or if you need further assistance, please let us know. We're here to help guide you in the right direction and suggest additional resources or steps as needed.

Warm Regards,
Erzsi
