Watch out for

HTML rendering engines often ignore external stylesheets so you must inline all CSS rules directly into the HTML tags.
Currency formatting can cause alignment issues in tables so always pad numbers with leading zeros or fixed decimal places.
Google Drive API quotas may be exceeded if many invoices are generated simultaneously so add a small delay between uploads.
Email attachments have size limits that vary by provider so compress the PDF or use a cloud link for large files.
