Best checkout & cart platforms in 2026
On score, Ticket Tailor comes out on top: no subscription and no percentage commission, just a small flat fee per paid ticket, with free-entry tickets at no cost. It's built for selling event tickets, though, not digital products. If you sell downloads, courses or software, compare Payhip (free to start, 5% per sale on the free plan and 0% on Pro), Lemon Squeezy (5% + 50¢ per sale, with global tax handled for you) and SamCart (high-converting checkouts and one-click upsells for a flat monthly price with a 0% platform fee).
The right pick really turns on your fee math. Flat-rate carts (SamCart, SendOwl, PayKickstart, Stan Store) charge a fixed monthly price and take 0% of sales, so they win at higher volume. Merchant-of-record platforms (Lemon Squeezy, Paddle, FastSpring) charge ~5-6% per sale but handle global tax and VAT for you, ideal for software when compliance matters more than margin.
