Anyone integrate Stripe into NetSuite before? ~ how many hours did that take?

There is a company called suitesync.io that has the integration. Depending on the scope and your proficiency with both then you are probably looking at 100-150 hours

I think that Stripe acquired suitesync?

Yes they did

Stripe acquired Suitesync and they work with Myers holum in USA to implement. there is no off the shelf connector. Every implementation cost a bit

@_ludlow We had quote of 6000 USD from Myers-Holum for NetSuite and Stripe integration based on our business requirements but we decided to go with Braintree
