What options are there for external landing pages that capture payment information? We don't need a full shopping/checkout experience, so SuiteCommerce doesn't seem like a match. These landing pages would be distributed to new customers, so the Customer Center isn't an option here. Can online forms be leveraged here? I'm concerned about PCI compliance.

I had to resort to building a suitelet to take in payments through our gateway.

2021.2 release has native support for this

Yes NetSuite added this to their latest release Also MerchantE has an app to add a Pay Now button to your invoices for customers to click and remit payment

Doesnt reference my account still have a checkout?

The external payment page in 2021.2 is part of SuiteCommerce. If that's not one of your modules you can't use it.

@Travis Zuri I was able to set it up in our release preview account without SuiteCommerce, and don't see that requirement mentioned anywhere in the documentation

Oh, maybe I should have just tried it, our NetSuite rep said I had to have SuiteCommerce when I asked him about the feature
