Hello there, @Denisplpro.

I'd feel the same if some features aren't working, like changing the logo size, in QuickBooks Online (QBO). I want to ensure you can change the size of the logo so you can get back to working order.

To clarify, have you tried performing all the troubleshooting steps shared by my colleagues above? If you haven't yet, I suggest doing it so.

If you get the same result after performing the troubleshooting steps, I recommend contacting our QuickBooks Support Team. This way, they can further check on this matter and provide in-depth troubleshooting steps to get this resolved. They can also create an investigation ticket if other users are experiencing the same.

To reach them, you can follow the steps below:

1. Sign in to your QuickBooks Online account.
2. Click the Help button.
3. In the QuickBooks Assistance chatbox, select Talk to a human and choose I still need a human.
4. Select Contact Us.

Just in case you want to add custom fields to your sales forms in QBO, you can check out this article for more guidance: Add custom fields to sales forms and purchase orders in QuickBooks Online.

Feel free to leave a comment below if you have other concerns or follow-up questions about this. The Community forum is always open to help.

My client currently uses Word for her invoices and her logo stretches across the entire top of her invoices.  She is new to QB and can't understand why her invoice cannot look the same as it does in Word.  Even if we make it Centered and Large, it doesn't stretch all the way across the top.  How do I do that?

Welcome to the Community space, @JamieCC1.

Your logo is an essential element in establishing your company's brand and personality. In QuickBooks Online (QBO), you can add a logo and customize it so it will look better. 

 Here are the specific logo requirements:

• a .gif, .bmp, .png, .jpg, .jpe, or .jpeg file
• smaller than 10 MB
• 24-bits or less in bit depth (or color depth)
• square-shaped since rectangles don't work
• using the standard RGB color space
• convert to an RGB image using tools (such as Adobe Photoshop) if your logo is CMKY-formatted. 

If you choose to resize the logo to Small, Medium, or Large, please note that the height and width of the logo will remain fixed and cannot be further changed. 

Once you ensure that your logo meets the requirements mentioned above, you can upload it to QBO. To add and make your logo larger, you can follow these steps:

1. Go to Settings, then select Custom Form Styles.
2. Click the Standard to edit. 
3. Go to the Design tab, then select Add your unique logo
4. Click Save, then adjust the size and placement of your logo as desired.
5. Once you've made the changes, select Done. 

Now, you can print and email your invoices. To learn more, check out this article: Email or print multiple sales forms.

Just to let everyone know, I FINALLY figured out a fix to this issue!! I used Illustrator for this so my instructions will be for someone using Illustrator. Hopefully you can figure out how to make the necessary adjustments for the program you are using.

1. Go to "New File"
2. Width > 184 px
3. Height > 80 px
4. Color Mode > RGB Color 
5. Raster Effects > High (300 ppi)
6. Click "Create"
7. Add your logo to the Artboard
8. Then go to "File > Export > Export As > Save as type: JPEG

I sincerely hope this helps someone because it was very frustrating for me while trying to figure out!
