A straight, feature-by-feature look at how the two compare - pricing, invoicing, payments, and everything in between. Every Cosmobill claim here is enforced in the product; every Square data point is sourced from squareup.com's own pricing/feature pages and official fee schedule.
Square's free plan is unlimited on invoice volume where Cosmobill's caps at 5/mo - but Square has no PayPal option and no time/expense tracking at any tier. See the full table below for everything else.
Square details above come from squareup.com's official invoicing fee schedule and Square's own press materials on Invoices Plus, as of when this page was written - pricing pages change, so if something here looks off, treat squareup.com as the source of truth for their current plans. Worth flagging directly: Square's pricing is genuinely confusing right now because two separate structures coexist - an invoicing-specific "Square Invoices Plus" at $20/month (custom templates, milestone schedules, multi-package estimates), and a much broader unified "Square Plus" business subscription at $49/month covering point-of-sale, staff, and inventory management well beyond invoicing. This page compares against the $20/mo invoicing-specific tier since that's the direct analog to Cosmobill's own plans; if you land on Square's general pricing page you may see the $49/mo figure instead, which reflects a much wider product bundle. Square Invoices is a capable free product for anyone already in the Square ecosystem, with real strengths Cosmobill doesn't match - Afterpay checkout, batch invoice sending, and file attachments on its free tier among them. Where Cosmobill differs is PayPal checkout and built-in time/expense tracking, neither of which Square Invoices offers at any price. Every Cosmobill row marked available on a plan is a feature that actually ships in the product today, not a roadmap item.
