Shopify Third-Party Gateway Fees and Self-Hosting Math

Shopify still bills a separate transaction fee on every order a store routes through an outside payment gateway, and for sellers that Shopify Payments will not serve, that fee is a fixed cost of staying. The Shopify pricing page, checked on October 5, 2026, lists third-party transaction fees of 2 percent on Basic, 1 percent on Grow, 0.6 percent on Advanced, and 0.2 percent on Plus. Hemp and CBD shops, firearms accessory catalogs, and other restricted merchants pay it on top of their specialty processor’s rate. In June, Shopify’s removal of electronic nicotine delivery systems (ENDS) showed that the catalog behind those payments can be withdrawn on about two weeks’ notice.

This article is analysis. Fee schedules, policy language, and the ENDS timeline come from Shopify’s own pages and from Reuters reporting. Break-even figures and replatforming judgments are EC4IM calculations and are marked Analysis.

Which sellers pay the surcharge because Shopify Payments is closed to them

Shopify’s own page for CBD merchants states that “Shopify Payments doesn’t support the sale of hemp, cannabidiol (CBD), and tetrahydrocannabinol (THC) products” and points those stores to compatible third-party providers. Shopify continues to host hemp stores that meet its U.S. requirements, so the gateway surcharge is built into the business model for that group rather than imposed as a penalty.

Firearms-related goods sit behind a similar wall. A Shopify FAQ site that read the Help Center on August 30, 2026 quotes the Shopify Payments eligibility page as excluding “tobacco and related products, firearms, holsters, ammunition, or weapons,” among other regulated categories. EC4IM has not independently reloaded that eligibility page for this article, so the quotation is attributed to that secondary read. EC4IM earlier outlined what high-risk merchants build when Shopify Payments is unavailable.

Supplements are not named in that quoted eligibility line. A supplement brand meets the surcharge only when its card traffic runs through an outside gateway, whether by choice or after a processor review, and the math below applies to it on the same terms.

What the third-party fee is calculated on

The fee base is wider than the product price. Shopify’s Help Center page on third-party transaction fees on Shopify bills gives the formula as the cost of products minus discounts, plus tax, plus shipping charges, multiplied by the plan rate. The page also says the fees “aren’t returned to you when you issue an order refund” and are charged in addition to whatever the outside provider takes.

Shopify’s third-party payment providers page adds that the fees apply to all third-party and alternate gateways even when Shopify Payments is active. PayPal and manual payments are excluded only for stores that have Shopify Payments turned on, which leaves a store locked out of Shopify Payments without that exemption.

Analysis. Take a $120 order of hemp tinctures with $9 in shipping and $7.80 in sales tax on the Basic plan. The fee base is $136.80, so Shopify’s 2 percent comes to about $2.74 before the gateway’s own charge. If the buyer returns the order, the merchant refunds $136.80 and keeps paying the $2.74.

Where the Shopify plan tiers cross over

On yearly billing, the pricing page lists Basic at $29 a month, Grow at $79, and Advanced at $299. Plus starts at $2,300 a month. Each step up lowers the third-party rate, so a busy restricted store can buy its way down the ladder.

Analysis. Counting only the plan fee and the surcharge, Grow becomes cheaper than Basic once a store routes about $5,000 a month through an outside gateway. Advanced overtakes Grow near $55,000 a month, and Plus does not overtake Advanced until roughly $500,000 a month. The table below uses the same two cost lines and ignores feature differences between plans, app subscriptions, and the gateway’s own pricing.

Monthly gateway volume	Basic (2%, $29)	Grow (1%, $79)	Advanced (0.6%, $299)
$10,000	$229	$179	$359
$40,000	$829	$479	$539
$100,000	$2,029	$1,079	$899

A store on Grow processing $40,000 a month through a specialty gateway therefore pays about $5,750 a year to Shopify in plan and surcharge alone. Because tax and shipping sit inside the fee base, the real figure for a store that collects both will run somewhat higher than a product-revenue estimate suggests.

How the ENDS removal closed a category in two weeks

Reuters reported on June 23, 2026 that Shopify planned to bar vapes after pressure from a coalition of U.S. state attorneys general. On July 10, Reuters reported that Shopify had confirmed a June 24 merchant notice stating, “Due to changes in legal restrictions on the sale of Electronic Nicotine Delivery Systems (ENDS), Shopify no longer supports the sale of these products.” The notice told merchants to remove e-cigarette products by July 8 or risk product suspension or store termination. A spokesperson for California Attorney General Rob Bonta, who led the coalition with the City of New York, told Reuters the decision applies globally.

Token of Trust, an age verification vendor, wrote on June 25 that it had reviewed one of the notices and that it covered e-cigarettes, e-liquids, vaporizers, parts, and refills regardless of nicotine content. The company also reported that Shopify offered affected Shopify Plus merchants an early contract exit without penalty. Beyond confirming the notice, Shopify did not comment to Reuters.

Shopify’s Acceptable Use Policy, read by EC4IM on October 5, 2026, still does not mention vapes, nicotine, tobacco, or firearms. It works by principle and tells merchants they are “responsible for following the rules of your platform, your partners, and the law.” Rigby, a commerce development agency, made a related point in an August 18 review of the ban, noting that the policy had been equally silent in the week Shopify removed the category.

Analysis. Nothing in the public record says Shopify plans to remove CBD, firearms accessories, or supplements. Every surcharge projection a restricted seller builds still assumes the catalog survives the year, and the ENDS removal shows that assumption rests on a vendor decision that can follow outside regulatory pressure within weeks.

What self-hosting removes and what it adds

WooCommerce, the open-source commerce plugin for WordPress, says on its pricing page that the core platform is free, with “no platform fees, no revenue share,” and that payments carry only the chosen processor’s fees. The same page estimates hosting at $25 to $350 a month for most stores. Paid extensions, developer time, and security work come on top.

Analysis. A payback period is the simplest way to test a move. Add up what leaving Shopify removes each month, meaning the surcharge, the plan fee, and any Shopify-only apps. Subtract what self-hosting adds each month, such as hosting, paid extensions, and a maintenance retainer. Then divide the one-time migration cost by the difference. In a hypothetical case with a $10,000 migration and $150 a month in new hosting and extension costs, the $40,000-a-month Grow store above saves about $329 a month and breaks even in roughly 30 months. The same assumptions applied to a $100,000-a-month Advanced store produce a monthly saving near $749 and a payback of about 13 months. Real migration quotes vary widely and should replace these placeholders.

Analysis. At about $10,000 a month in gateway volume, the Basic or Grow surcharge runs $100 to $200 a month, which falls inside the $25 to $350 monthly hosting range WooCommerce cites. For those stores, fees alone seldom justify a rebuild. The calculation shifts once catalog risk enters it. A merchant whose revenue would collapse if a category were withdrawn is paying for control as well as lower fees.

Self-hosting moves work onto the merchant. A WooCommerce checkout needs patching, backups, and payment-page monitoring, which EC4IM covered in its guide to WordPress hardening for high-risk WooCommerce checkouts. The processor also remains a gatekeeper. Rigby’s review notes that the same attorneys general coalition wrote to nine payment companies in April 2026 about tobacco and nicotine sales, a reminder that no platform choice removes the acquiring dependency.

How the decision differs by vertical

CBD and hemp. Shopify hosts compliant hemp stores but sends their card payments to outside providers by policy, so the surcharge is permanent for as long as the store stays. Stores approaching the Grow-to-Advanced crossover have the most reason to model a move.

Nicotine. ENDS sellers no longer have a Shopify option under the June notice. The notice language Reuters quoted named ENDS only, so sellers of other nicotine products, such as the pouches covered in EC4IM’s nicotine pouch compliance checklist, should confirm their own standing with Shopify instead of reading it from the vape notice.

Firearms accessories. The eligibility line quoted by the FAQ site groups holsters with firearms, and the same source reports that the Shop sales channel refuses related accessories. EC4IM’s comparison of WooCommerce and BigCommerce for firearms accessory sellers covers platform fit for that group in more detail.

Supplements. Brands that qualify for Shopify Payments avoid the surcharge entirely, which makes self-hosting a question of catalog control rather than fees. Brands already pushed onto an outside gateway face the same ladder as CBD shops.

Fees, refunds, and catalog risk in one budget

Shopify’s third-party fee runs from 2 percent on Basic to 0.2 percent on Plus, applies to tax and shipping as well as products, and stays with Shopify when an order is refunded. Hemp shops and other sellers that Shopify Payments turns away pay it every month on top of specialty processing. The ENDS removal added a second cost that no fee table shows, because a hosted catalog can close in about two weeks. By EC4IM’s estimates, small restricted stores land near even after self-hosting costs, while stores routing $40,000 to $100,000 or more a month through outside gateways can recover a $10,000 migration in roughly one to three years under the same assumptions, before any value is placed on owning the catalog.
