If you would like to display a company logo on invoices and other correspondence, you need to upload a log in Company>My company:

There are requirements with regards to size and file type. The logo should ideally be a PNG or JPG imange between 150px wide and 150px long - if it is bigger than that on any of the size it will be resized by Rapid ERP and the results may be slightly inferior in image quality.

Once the image has been upload, you can select where in the header would you like it to appear - Centered (Top), aligned to the left (Left) or to the right (Right).
