Hey! I'm a PM at Stripe working on solving VAT/GST/sales tax pain points for our users. Would be great to connect and hear more about what you're looking for. Please do correct me if I'm wrong, but it sounds like your main pain point is around specifically handling the collection, and then remittance and filing of tax for all countries/jurisdictions you have nexus in? Or is it actually the difficulty with issuing customers compliant invoices across all countries you sell to (e.g. ensuring VAT ID is shown, language is local, etc.)?
Either way, would be great to connect -- kmoriarty@stripe.com
