Custom Excel Invoice Template

I need a clean, editable Excel invoice that already contains my company logo and a clear section for payment details. The sheet should let me list both product-based lines (item name, quantity, price) and service-based lines (service description, hours, rate) in the same document, with totals updating automatically.

Please set up the usual invoice header (invoice number, date, bill-to, ship-to) and build in the formulas so subtotals, any taxes I may add later, and the grand total calculate without extra work. A well-structured summary area that highlights the amount due will help the client spot it quickly.

The final file must be delivered in .xlsx format, unlocked for future edits, and designed so I can swap out the logo or tweak colours without breaking the formulas. If you’ve created similar templates before, a quick screenshot or sample would be appreciated.
