Thank you for your payment.

Response:

My Dearest Mr. Doe,

Pray, permit me to take pen in hand and offer, with the utmost sincerity and gratitude, my profound thanks for your timely and generous remittance. Rare indeed is the pleasure that I derive from correspondence of such a felicitous nature, and rarer still is the privilege of addressing a gentleman of your esteemed character and noble disposition.

Your payment, received with all due ceremony, has graced our humble establishment like a ray of golden sunlight filtering through the ancient boughs of a venerable oak. It is not merely the settling of accounts that stirs my heart, but rather the cherished confidence you bestow upon us—a trust which we hold as dearly as any precious relic or priceless heirloom.

Allow me to assure you, most honourable sir, that your patronage is the very lifeblood of our humble enterprise. You have, with a stroke of your pen, renewed the bonds of commerce and camaraderie which unite us, and for this, I am ever in your debt.

May fortune and felicity attend your every step, and may the days to come bring you as much satisfaction as your esteemed custom has brought to us. Should you require aught, whether great or small, pray do not hesitate to command our service, for it would be our greatest pleasure to attend to your wishes with the utmost devotion and alacrity.

With deepest respect and abiding appreciation, I remain— Your most obedient and grateful servant,

[Your Name] [Your Title or Company, if applicable]

I fell like I should change my default invoicing letter. Much better than the default QuickBooks one.
