Poscow: Upgrade international checkout for Squarespace online store

I’ve struggled with Squarespace’s limitations—clunky international shipping quotes, confusing tariff, no VAT/GST automation, and basic discount options. It’s frustrating when tools like TaxJar fall short and customers assume we’ve got it covered. That’s why I built PosCow, a plugin that seamlessly upgrades your Squarespace checkout to: Show instant international shipping rates (powered by GoShippo). Auto-calculate VAT/GST with Stripe Tax, tailored to your business thresholds. Unlock flexible discounts (think BOGO, Buy2AGet1B, loyalty perks, and more). We’re launching PosCow in beta, and I’m inviting a select group of US-based Squarespace stores to join early. As a beta user, you’ll get direct support from me directly, anytime and of course, a say in shaping the future tool. Spots are limited to keep this beta tight-knit.
