I’m unable upload a company logo any ideas how as it keeps saying make sure I own the logo, which I do and under the 2Mb size?

I'll make sure you can upload your company logo in QuickBooks Online (QBO), Michael.

I appreciate you for sharing the details of your concern and ensuring the size of your logo. 

Aside from the logo size, you also want to ensure the company logo is in a .gif, .bmp, .png, .jpg, .jpe, or .jpeg file format. This way, you can efficiently upload it in your QBO. 

Once you have your logo in one of those file types, you can refer to these steps on how to upload it to your QBO account.

1. Go to the Gear icon and select Custom form styles.
2. From the New style drop-down, select the appropriate form type.
3. Go to the Design tab, then select Add your unique logo.
4. Select the box with Add a logo +, then the plus icon on the next window.
5. Locate and select the image you want to use.
6. Select Open. Once uploaded, click Save, then Done.
