Ecommerce Platforms With No Transaction Fees: The Real Math

No ecommerce platform makes card payments free — someone always pays the processor. What "0% transaction fees" should mean is that the platform takes nothing on top of your processor's rate. ShopsWired, BigCommerce, and self-hosted WooCommerce all charge 0% platform fees; Shopify charges an extra 0.5–2% (by plan) only when you use a payment provider other than Shopify Payments. On $500K a year, a 2% surcharge is $10,000 — more than most platforms' entire subscription cost.

Two fees, one checkout — learn to separate them

Every card payment you take is really two charges stacked in the same line item, and merchants routinely blame the wrong one.

• The processor fee. What Stripe, Square, PayPal, Adyen, or your merchant acquirer charges to move the money. In the US this is usually somewhere around 2.9% + 30¢ for online card payments, with lower negotiated rates as volume grows. This fee is unavoidable — it pays the card networks, the issuing bank, and the processor. No platform can make it disappear.
• The platform surcharge. An extra percentage the software takes for the privilege of letting the transaction happen on their system. This one is pure margin for the platform. It is entirely avoidable, and it's the only number worth shopping around for.

When a platform says "no transaction fees," it should only ever mean the second one. If a page says "no transaction fees" and then quietly charges you 2% because you brought your own gateway, that isn't 0% — that's a gateway lock-in fee with better copywriting.

Where the major platforms actually land

Published pricing changes, and regional rates differ — always confirm on the vendor's own pricing page before you commit. As of this writing, the shape of the market looks like this:

Shopify

No additional platform fee when you use Shopify Payments. Use any other gateway and Shopify adds a per-transaction fee that scales down with your plan tier — roughly 2% on Basic, 1% on the mid tier, and 0.6% on Advanced, with lower rates on Plus. That's a real, defensible business model: they subsidize the platform with payments revenue. But it means "0% transaction fees" is conditional on using their processor, and if you have a negotiated rate elsewhere, an existing merchant account, or you sell in a country where Shopify Payments isn't available, the surcharge is your problem.

BigCommerce

0% platform transaction fees on every plan, with your choice of gateway. The catch isn't a percentage — it's the annual online sales thresholds attached to each plan. Cross one and you move up a tier. It's a revenue-linked cost, just billed as a plan upgrade instead of a percentage.

WooCommerce / self-hosted

No platform surcharge, because there is no platform company in the middle. You pay hosting, and you pay in labor: updates, plugin conflicts, security patching, performance work, and someone on call when checkout breaks on a Saturday. For a lot of stores this is genuinely the cheapest option on paper and the most expensive in practice.

Wix and Squarespace

Both have moved to 0% platform transaction fees on their commerce plans. They're strong for small catalogs and content-first sites; the trade-off shows up later, in how far you can customize checkout logic, pricing rules, and B2B behavior.

ShopsWired

0% platform transaction fees on every plan, with any gateway. You connect one active payment provider per store — Stripe, Square, PayPal, and others — through a gateway plugin, and the processor's standard rate is the entire cost of taking money. We don't get a cut of your sales, so we have no incentive to steer you toward a particular processor.

The savings curve

The math is simple, and it's the whole argument:

annual surcharge = annual online revenue × platform fee %

$250,000 × 2.0%  =  $5,000/yr
$500,000 × 2.0%  = $10,000/yr
$500,000 × 1.0%  =  $5,000/yr
$1,000,000 × 0.6% =  $6,000/yr
$2,000,000 × 0.6% = $12,000/yr

Two things jump out. First, the surcharge grows with revenue while a flat subscription doesn't — so the gap widens exactly as you succeed. Second, the tiers that reduce the percentage are also the expensive ones, so you're often paying more subscription to pay less percentage, and the crossover is worth calculating rather than assuming.

Compare total platform cost, not headline price. A $39/mo plan with a 2% surcharge on $500K of revenue costs $10,468 a year. A $99/mo plan with no surcharge costs $1,188 a year regardless of whether you do $200K or $2M. Run your own numbers on our pricing page before you decide anything based on the monthly figure alone.

The fees nobody puts in the comparison table

Platform surcharge is the loudest cost, not always the biggest. When you're modeling the real number, count these too:

• App subscriptions. The most common way a "cheap" plan gets expensive. Subscriptions, B2B price levels, product reviews, advanced search, faceted filtering — on some platforms each of those is a monthly app bill. Check what's native before you compare plans. On ShopsWired, subscriptions and recurring billing, tiered B2B pricing, quantity price breaks, faceted search, a visual page builder, custom domains with SSL, and transactional emails ship with every store.
• Gateway lock-in. If you can't leave a processor without paying a penalty, you can't negotiate with it. A 0.2% improvement on your processing rate is worth real money at volume, and only available if switching is free.
• Currency and cross-border fees. These sit with the processor and are easy to forget when you expand into a second market.
• Revenue-linked plan thresholds. A percentage by another name. If your plan tier is tied to annual sales, model the upgrade you'll hit next year, not the plan you're on today.

Being straight about our own trade-offs

0% is real on ShopsWired, and it isn't the only line on the bill. Our pricing is a flat per-shop subscription — Pro at $99/mo, Business at $249/mo, Enterprise at $499/mo, plus a Dedicated single-tenant option — with pay-as-you-go compute for container jobs on top. Container jobs are opt-in, they're for heavy work like image processing, PDF generation, OCR, scraping, and builds, and you set a monthly compute budget cap yourself. Settings → Usage shows storage, compute spend against your cap, and your plan's rate limits, so the variable part is visible before it's a surprise.

Higher tiers buy you throughput, background-task capacity, storage, scheduled-job frequency, and longer data retention — not a lower cut of your sales, because there is no cut. Live chat support comes with Business and Enterprise; Pro gets email and the documentation.

The honest summary: if you're doing $50K a year, a percentage-based platform may well be cheaper than any flat subscription, and you should take that deal. The math flips somewhere in the low-to-mid six figures, and after that it never flips back.

How to check a platform in five minutes

1. Find the phrase "transaction fee" on their pricing page and read the footnote attached to it.
2. Ask specifically: what is the fee if I use my own payment gateway instead of yours?
3. Ask whether plan tiers are tied to annual sales volume.
4. List the features you need, and check which are native versus paid apps. Price the apps.
5. Multiply your projected 12-month revenue by the surcharge, and add the subscription and the apps. That total is the comparison.

Do that for three platforms and the decision usually makes itself. Growth is the thing that should cost you more in fulfillment and ads — not in software rent on every order you've already earned.
