Hi, how do I put my own logo on the estimates/invoices?

Hi there, glowgreen.

I'm glad to have you here and be able to help you add your own logo on the sales form.

We can use the Custom form Style feature to attach a logo in the invoices. It helps personalise your sales forms and provide business branding by adding your company details especially attaching your own logo.

Let's follow the steps below to get these things possible. Here's how:

1. Go to the Gear icon.
2. Select Custom Form Styles under Your Company.
3. Click the New style drop-down arrow at the upper-right corner. If you have an existing template and want to add a logo there, just locate the invoice template. Then, hit Edit under the Action column.
4. Under the Design tab, hit the Make logo Edits section.
5. Click the Plus sign icon and select the file. 
6. Hit Save, then Done.

QuickBooks recommend these things to add your logo successfully and in a timely manner:

• square-shaped
• a .gif, .bmp, .png, .jpg, .jpe, or .jpeg filesmaller than 10 MB
• 24-bits or less in bit depth (or colour depth)
• using the standard RGB colour space. ​​​​​

Also, I encourage you to visit these articles. Each of them contains further information about the process and tips on how to design your templates:

• Add, customise, or remove logos on sales forms.
• Customise your invoices, estimates, and sales receipts in QuickBooks Online.

• Import custom form styles for invoices or estimates.

Let me know if you need further assistance with the process. I want to make sure that you'll be able to do it. Take care!
