No change required. Zen Cart is smart enough to send the right URL from each separate store.
You'll find answers to this and many other questions in the FAQs area: https://www.zen-cart.com/tutorials/index.php?article=229
In the FAQ, you mention:
"There is one caveat: Your customers will see the name of your PayPal account when making payment ... even if that doesn't match your store's name."
It's true. This is a fairly big negative since consumers may be confused or dismayed by seeing "Soulless Corp" in big letters at the top of the page when they jump over to paypal to make their payment...especially since they were ordering a product from "funkypants.com"!
One nice way to minimize this shock effect is to create different page styles over at paypal.com that will match each of your incoming websites in style. You can do this at paypal.com in the Profile section by clicking on "custom payment page styles". You will see the default page style when you view that page, then just click on "add" to make a new style. Name it, for example, "funkypantsstyle", enter a funkypants logo URL, set a funky background color, etc., then click save. Do this again to create a different style page for each of your incoming websites (e.g. funkypants.com, monkeyfood.com, etc.).
Now go back to your Zen Cart admin page for funkypants.com. Click on modules, then payment, then select the paypal module. Edit this module and change the page style from Primary to funkypantsstyle. Save.
Next time your customer is making a payment, when they jump over to Paypal, a nice big funkypants logo will appear on the top of the paypal page. Sure, it will still have "Soulless Corp" printed in a couple of places on the page, but it will not be as disturbing to the consumer with the big funkypants logo showing at the top of the page.
OK, not ideal, but that's the best I could come up with based on the limitations of current Paypal system.
