I can even provide you some templates which is exceptional than the usual one available in Xero.
1. Send me specimen as you like to see it in Xero.
2. Invite me in your Xero account with access level at least Standard to test the docx file.
3. Relax and I will knock you to review the outcome and seek your feedback. No worries I will edit until you find it as per your desire (subject to inherent limitations of Xero).
$30 for each DOCX file
$20 for each additional one after first one.
For first one it will be USD30 and for next each ones it will be USD20 only for the same company.
Yes I am a professional chartered accountant so that wouldn't be a problem.
