Int’l sales tax compliance -- What service to use?

Stripe says we need to start collecting sales tax/VAT for the UK, Switzerland, EU, a couple provinces in Canada, and UAE.

Who should we use for this stuff?

I know taxjar does US, and our accountant suggested Avalara for international but I’ve heard they’re expensive and don’t have great support.

If it matters, we’ll probably be adding PayPal as a payment method down the line in addition to stripe.
