Hi there, 050260tt. Thank you for your prompt response on the thread.

I see where you're coming from, there could be various reasons why the company is not displaying. One possible reason might be that the customer's display name matches their name.

Here's how you can edit your customer's file:

1. Go to Customers.

1. Next, click the customer's name.
2. On the upper right side, click Edit. 

1. Under Customer's Display Name, please edit the display name of your customer to their company name.

1. Click Save.

Once done, you can see the company name on the invoice itself.

Please note: That if you fill in the first and last name of your customer, it will also appear on the invoice. Additionally, the name on the screenshots is sample only. If issue persists, can we please have a screenshot to see your set-up.
