For the past several months I have used PayPal's invoicing. (Not been doing this for years and years.) Admittedly, I opted for this because of its ease of receiving payment and its ease of use. I am not a bookkeeping whiz nor am I an accountant. So PayPal has made invoicing and receiving payments so easy. And maybe I've been lucky. I send out my invoice, and boom, the next day I receive a message that I have received payment!

(I'm assuming this may not always be the case.)
What I just don't like is that I can't customize what my invoice looks like. Is that egotistic? I suppose the main purpose of sending out an invoice is to receive payment -- not a time to demonstrate creative skills . . . BUT I WANT TO DO THAT!
Have I gotten carried away with my invoices? Don't answer that. I get carried away with everything!
Does anyone else use PayPal for invoicing, and if so, do you know of any secrets to customize your invoice?
