There might have been a change in the integration between Harvest and QuickBooks Self Employed (QBSE), Sylvie.  I'm here to help point you in the right direction. 

To resolve this issue effectively, I recommend contacting Harvest support directly. They can provide detailed insight into any recent updates that may be impacting this feature and help you find a solution. 

I'm providing this resource to help you personalize your invoice. Adjusting the design, layout, and information fields allows you to create invoices that reflect your brand and offer clearer, more detailed information to your clients. For more details, please check out this article: Create and customize invoices in QuickBooks Self-Employed.

If there's anything else you need assistance with or if you encounter any further issues, please don't hesitate to reach out, Sylvie. I'm here to ensure everything runs smoothly for you.
