In case the size of your own signature is disproportionally big compared to the signature of your client on your quotation, you do the following.
- Click on your name/picture in the right hand top corner
- Click on "My account"
- Click on "Create now" next to "Signature".
- You need to upload your signature in the exact size that you want to see on your quotation.If you have no experience with resizing images you can find some tutorials over here.
