Best checkout for digital products in 2026 (fees compared)
The best checkout for digital products in 2026, with honest fee math: SamCart's 0% cart vs merchant-of-record tools like Lemon Squeezy and Paddle.
The best checkout for digital products in 2026 is SamCart for most sellers — its high-converting pages and one-click upsells come with a 0% platform fee, so you keep your revenue minus payment processing. But the right pick turns entirely on your fee math and whether you want someone else to handle global sales tax. This guide does the honest math so you can choose.
There are two kinds of checkout for digital products, and confusing them costs you money.
Flat-fee carts vs merchant-of-record
Flat-fee carts (SamCart, ThriveCart) charge a fixed monthly or one-time price and take 0% of your sales. You handle your own sales tax. They win as volume grows because their cost doesn’t rise with revenue.
Merchant-of-record (MoR) platforms (Lemon Squeezy, Paddle) charge a percentage per sale — around 5% + 50¢ — but become the legal seller of record. They remit VAT and global sales tax for you and bundle payment processing into that single fee. You trade margin for zero tax compliance.
The trap: a percentage fee feels small on one sale and brutal at volume. The honest math below shows where the lines cross.
The fee math, honestly
Here’s what each tool actually costs. Flat-fee carts list a monthly or one-time price; MoR and pay-per-sale tools list their cut. Processor fees (typically ~2.9% + 30¢ via Stripe/PayPal) apply on top of flat-fee carts but are bundled into the MoR fee.
| Tool | Model | Price / fee | Handles tax? |
|---|---|---|---|
| SamCart | Flat-fee cart | $59/mo (annual), 0% platform | No |
| ThriveCart | Pay-once cart | $495 one-time, 0% platform | No |
| Lemon Squeezy | Merchant of record | 5% + 50¢/sale, $0/mo | Yes |
| Paddle | Merchant of record | 5% + 50¢/sale, $0/mo | Yes |
| Gumroad | Pay-per-sale | 10% + 50¢/sale, $0/mo | Yes (VAT) |
| Payhip | Freemium cart | 5% (free) → 0% ($99/mo) | Yes (VAT) |
A worked example. Say you sell a $50 product, 100 times a month — $5,000 in revenue:
- SamCart: $59 flat. Your effective platform cost is roughly 1.2% of revenue, and it falls as you sell more.
- Lemon Squeezy / Paddle: 5% + 50¢ × 100 = $300 in MoR fees on that $5,000 — but tax compliance is handled.
- Gumroad: 10% + 50¢ × 100 = $550. Easy, but the priciest at this volume.
At low or unpredictable volume the math flips: a $0/mo pay-per-sale tool costs nothing until you make a sale, while SamCart’s $59 is due regardless. Drag your real numbers in the pricing calculator to see exactly where you land.
SamCart — the conversion-first pick
SamCart is built for one thing: converting checkout pages. Its Core plan is $79/mo ($59 annual) with a 0% platform fee, and the one-click upsells, order bumps, and cart-abandonment recovery are designed to lift average order value. No free tier and only a 7-day trial, so it suits sellers with enough volume that $59/mo is trivially repaid. If keeping your revenue and maximizing each sale matters more than offloading tax, start here.
ThriveCart — pay once, own it
ThriveCart is the same fee-free, upsell-heavy idea as SamCart but with a genuine one-time price: $495 for the Standard lifetime license, no monthly bill, no cut on sales. The newer Pro+ feature set adds $295/yr from year two, but the core cart stays pay-once. If you’re confident you’ll keep selling, the lifetime license pays for itself within a year versus any monthly cart. See SamCart vs ThriveCart for the head-to-head.
Lemon Squeezy and Paddle — let someone else handle tax
Lemon Squeezy and Paddle are merchant-of-record platforms: both charge 5% + 50¢ per sale with no monthly fee, and both become the legal seller so they remit global VAT and sales tax for you. Lemon Squeezy adds a 1.5% surcharge on international and PayPal payments; Paddle’s effective rate rises with its currency-conversion spread. These are the right call for software and SaaS, or any seller in many tax jurisdictions where compliance would otherwise eat an accountant’s fee. Compare them in Paddle vs Lemon Squeezy.
Gumroad and Payhip — easiest to start free
Gumroad is the simplest way to sell within minutes: no monthly fee, 10% + 50¢ per direct sale, and it handles VAT and delivery. The 10% is high once you’re selling regularly — see the math above — but it costs nothing until you do. Payhip is a similar freemium route: 5% per sale on its free plan, dropping to 2% then 0% on paid tiers, with built-in EU VAT. Both are great for validating an offer before committing to a paid cart.

FAQ
What’s the difference between a flat-fee cart and a merchant of record? A flat-fee cart like SamCart charges a fixed price and takes 0% of sales — you handle your own sales tax. A merchant of record like Lemon Squeezy or Paddle charges ~5% + 50¢ per sale but becomes the legal seller, remitting global VAT and sales tax for you.
Do these fees include Stripe or PayPal processing? For flat-fee carts (SamCart, ThriveCart), no — standard processing of ~2.9% + 30¢ is charged separately by Stripe or PayPal. On merchant-of-record platforms (Lemon Squeezy, Paddle), processing is bundled into their single 5% + 50¢ fee.
Which checkout is cheapest at high volume? Flat-fee carts win as you scale because their cost doesn’t grow with revenue. At a few thousand sales a month, SamCart or ThriveCart’s 0% platform fee beats Gumroad’s 10% or Lemon Squeezy’s 5% + 50¢, which keep climbing per sale. Check your numbers in the pricing calculator.
Is ThriveCart really a one-time payment? Yes — the ThriveCart Standard license is a genuine one-time $495 with no monthly fee and no platform cut on sales. The Pro+ feature set carries a $295/year cost from year two, but the core cart stays pay-once.
