New here, and trying to finish a project

Hi there! I stumbled upon this website and was surprised with the vast amount of useful information I can get here about a variety of financial subjects. I could REALLY used someone's help here... I'm finishing up a final project for my master's degree, which includes building a marketing campaign for a specific product bank in my country. The thing is, I'm stuck at the slogan! I've done everything else, but the slogan is literally killing me. I'm not a native english speaker, and because the slogan needs to be in english, I can't really find a way to confirm which term adapts better. I found many websites with witty financial terms, but without proper context it's really like shooting in the dark here.

The message I want to pass on is: We can guarantee your payments to your supplier, and opposite to that, the collections you are about to make from your customers. It's basically a type of factoring system, but with a implemented guarantee behind it. Because of this guarantee, the company that sold something and is collecting the payment can request an anticipation to the bank, without the customer being charged early. It's like I request a loan until the payment is settled.

I had many slogans ready, but the ones I like the most are:
Secured Payments, Early Collections
Guaranteed Payments, Early Collections.
Secured Payments, Flexible Collections.
Early and Secured Settlements.

I also thought of using terms such as Safer, Anticipation

I guess my questions are:

- Are these terms "Secured, Early, Flexible" the most adequate in a bank/financial context, considering what I'm looking for? What would be the best option to use here? Even my english friends are not working in this area and cannot give my a conclusive opinion :|

Any feedback would be of course most welcome, and I apologize humbly for my intrusion in this domain, and if I crossed the line by asking help like this.

Cheers!
