Customize invoice template

I need the invoice template ready for clients by Monday. Update our current invoice so the service description shows first, the VAT line is labeled "Tax (VAT 20%)" and the due date is highlighted in red when overdue. Use our company name Freelance Press, include bank details and a footer with "Payment terms: Net 14". Check layout on mobile before saving the template.

Before I send this to clients, make the invoice easier to approve: move the total due to the top-right, bold the savings or discount line so it is obvious, and add a one-line note that explains what is invoiced (for example: "June copywriting retainer, 12 hours"). Flag any missing legal or tax details that would make a client pause.

I was editing the Freelance Press invoice template and the service descriptions rearranged unexpectedly; the VAT label reverted to "Tax" and the due date formatting disappeared. I need to send this to three recurring clients on Friday and I’m worried invoices will look unprofessional. Tell me the most likely cause and the exact fixes I should apply now so I can send clean invoices.

Every few months our invoice templates lose the VAT label and render badly on phones, costing me hours fixing and sometimes a late payment. Where is this pattern coming from — user error, template versioning, or export quirks — and what routine should I adopt so the invoice template is stable and always mobile-friendly? Give one small habit to change first.
