All platform, processing, and marketplace figures reflect 2026 published pricing verified against Shopify, Stripe, and Amazon official rate pages; cost ranges are estimates and vary by business model, product category, and location.
TL;DR — Quick Verdict
- A lean solo store realistically launches for $500–$5,000; a branded store with inventory and paid ads runs $10,000–$50,000+ in the first 90 days.
- Shopify’s Basic plan costs $39/month ($29/month billed annually), but the platform fee is under 15% of true first-year spend — inventory and customer acquisition consume the rest.
- Payment processing is the tax you never escape: Shopify Payments and Stripe both charge 2.9% + 30¢ per online sale on entry tiers, meaning roughly $3.20 on every $100 order.
- Amazon’s Professional plan ($39.99/month) plus referral fees (default 15%) plus FBA fulfillment typically consume 30–45% of each sale’s price — far more than Shopify’s stack for most sellers.
- The average e-commerce customer acquisition cost now sits at $68–$84 and has climbed roughly 40% since 2023, making marketing the single most underestimated line item.
- Recommendation: Start on a hosted platform’s entry plan, keep your app stack lean, and budget for acquisition before design — the store is cheap; the customers are not.
Software is usually the smallest slice of what it costs to run an online store — often under 15% of true first-year spend, according to 2026 industry cost breakdowns. Yet nearly every “start for $29” pitch anchors new founders on the platform fee and ignores the two line items that actually decide profitability: inventory and customer acquisition. The result is a store that launches beautifully and bleeds quietly.
Real numbers vary enormously. A lean dropshipping-style launch on Shopify Basic can go live for $500–$2,000, while a branded store with held inventory, custom design, and paid ads routinely crosses $10,000 before its first sale, per 2026 launch-cost data from multiple e-commerce analysts. This guide breaks down every real cost layer — platform subscriptions, payment processing, marketplace fees, apps, and marketing — with the arithmetic each carries. We name the three platforms most founders actually compare (Shopify, Amazon, and Stripe) and model the monthly math so you can plan with figures instead of slogans.
What E-Commerce Setup Actually Costs in 2026
Startup spend splits into one-time costs (entity registration, initial website build, first inventory buy) and recurring costs (platform subscription, apps, processing fees, marketing). The one-time bucket is where the widest ranges live, because “a store” can mean a $500 template or a $25,000 custom build.
Registering a U.S. e-commerce business runs roughly $130 to $1,000 depending on state and whether you file yourself, with an LLC being the most common structure for new sellers. Website design sits on top of the platform fee: a template-based store runs $500–$5,000, while a custom-designed site with unique branding typically costs $5,000–$25,000 and enterprise builds exceed that. If you’re weighing a done-for-you approach against a DIY build, the tradeoffs mirror those in any business website build vs buy pricing decision.

Notice what dominates the branded column: inventory and marketing, not software. That pattern holds across nearly every serious launch, which is why founders who obsess over the $39 subscription and ignore the $5,000 ad budget consistently run out of runway.
Platform Subscription Costs: Shopify Plan by Plan
Shopify runs the most-searched pricing table in e-commerce, and 2026 brought a rename. The former “Shopify” mid-tier is now “Grow,” and every paid plan carries a 25% discount when billed annually.

The card rate matters as much as the subscription. Move from Basic (2.9% + 30¢) to Grow (2.7% + 30¢) and you save 0.2% on every online sale — worthwhile only once volume makes that fraction exceed the $66/month plan gap. That break-even lands near $8,000 in monthly sales, per 2026 platform analysis. If you’re comparing Shopify against a franchised retail model with prescribed systems, the calculus resembles the broader franchise vs independent cost comparison. One more trap: using a third-party payment gateway instead of Shopify Payments adds a surcharge — 2% on Basic — on top of your processor’s own fee.
Payment Processing Fees: The Cost You Can’t Design Around
Every sale carries a processing fee, and the headline rate rarely tells the whole story. Stripe’s standard U.S. rate is 2.9% + 30¢ per successful online card charge, with no monthly or setup fee on the standard plan — so a $100 sale nets you $96.80 after $3.20 in fees.
That flat 30¢ is punishing on small baskets. On a $10 order, the same 2.9% + 30¢ works out to 5.9% effective, nearly double the rate on a $100 order. Founders selling low-priced items feel processing fees far more sharply than the percentage suggests, which is why average order value belongs in every pricing model. Getting that number right is the core of pricing with margin and overhead.

Two levers reduce this cost. First, ACH: at 0.8% capped at $5, a $1,000 B2B invoice paid by bank transfer costs $5 instead of $29.30 on a card — a meaningful saving for wholesale sellers. Second, volume: merchants processing past roughly $5M annually can negotiate interchange-plus pricing below the flat 2.9%, but only if they ask. Whether you route payments through your storefront or a separate terminal, the same fee logic drives POS hardware and processing fees.
Shopify Store vs Amazon Marketplace: Which Is Cheaper to Operate?
The fee structures are built differently. Shopify charges a fixed subscription plus a card rate you control by using Shopify Payments. Amazon charges a subscription plus a referral commission plus, if you use fulfillment by Amazon, per-unit fees — a stack that compounds.
Amazon’s Professional plan costs $39.99/month with no per-item fee, while the Individual plan charges $0.99 per item and blocks ads, the Buy Box, and repricers. Referral fees run 8–17% by category, defaulting to 15%, and Amazon froze those percentages for both 2025 and 2026. FBA fulfillment fees rose an average of $0.08 per unit effective January 15, 2026. Together, Amazon’s fee stack typically consumes 30–45% of a product’s selling price, per multiple 2026 seller-fee breakdowns.

Verdict
For a brand building a repeat-customer base, Shopify is dramatically cheaper to operate per sale — its platform take runs roughly 3.5% versus Amazon’s 23–27% once referral and fulfillment stack. But Amazon buys you built-in traffic and Prime eligibility that Shopify never provides. The honest answer: Shopify wins on unit economics; Amazon wins on customer acquisition. Many sellers run both — Shopify for margin and brand, Amazon for volume and discovery.
Monthly Operating Costs: Apps, Themes, and the Recurring Stack
The subscription is the floor, not the ceiling. Around 87% of Shopify stores use paid apps, averaging six per store, and most stores spend $200–$1,000/month on apps once the base platform is running, per 2026 e-commerce cost data.
Build a realistic monthly budget from the ground up. A lean solo store’s genuine fixed cost lands around $30–$70/month plus processing, if the owner uses a free theme and keeps apps minimal. A growing brand’s stack looks very different — email marketing, reviews, abandoned-cart recovery, and analytics apps push recurring software past $350/month before ads.

These recurring costs are where the “cheap store” myth dies. If you’re planning to bring on help to manage fulfillment or customer service, layer in the true cost of hiring a first employee — and decide early whether that role is a hire or a contractor, because the employee vs contractor cost difference carries real misclassification risk.
Marketing: The Line Item Everyone Underestimates
Here’s the number that reshapes every budget: the average e-commerce customer acquisition cost now sits at $68–$84, and it has climbed roughly 40% since 2023, per 2026 aggregated benchmark data from Ringly.io and Mobiloud. Google Ads CPCs rose 12.88% year-over-year, and Meta CPMs jumped 20%, so every dollar buys less reach than a year ago.
CAC varies wildly by vertical. Pet brands win at around $23, supplements hit roughly $89, and luxury goods can top $120, according to 2026 DTC benchmark data. A store selling $50 products at an $80 CAC is underwater on the first order and depends entirely on repeat purchases to survive — which is why lifetime value, not CAC alone, decides whether a brand is viable.
Most new store owners start with $500–$1,000/month on marketing, though disciplined founders begin near $0 with organic social and SEO. If you’re sizing this line against revenue rather than guessing, anchor it to marketing budget benchmarks by revenue size. Whatever the figure, treat acquisition as a fixed cost of doing business, not an optional extra you add once sales appear — because without it, sales rarely appear.
What Most People Get Wrong About E-Commerce Costs
Three mistakes recur across nearly every failed launch, and each one traces back to mis-budgeting a specific line.
Mistake 1: Budgeting for the platform, not the customer. Founders memorize the $39 Shopify fee and never model the $80 CAC. Consequence: the store launches funded and dies unfunded within three months. Correct action: build your budget backward from acquisition cost times target orders, then add platform and inventory on top.
Mistake 2: Ignoring the processing math on low-price products. A seller listing $8 items assumes 2.9% is trivial, missing that the flat 30¢ makes the effective rate 6.6%. Consequence: margins vanish at scale. Correct action: model fees on your actual average order value, and raise AOV through bundling before scaling ad spend.
Mistake 3: Skipping legal and licensing groundwork. New sellers often launch without checking category-specific requirements, then face fines or forced shutdowns. Consequence: unplanned costs and downtime. Correct action: confirm your obligations up front — requirements vary sharply, as the range of business license and permit costs by industry shows. If you’re building a brand name worth defending, factor in USPTO trademark filing and attorney costs before a competitor claims it first.
Is Launching an E-Commerce Store Worth It in 2026?
The answer turns on margin and patience, not enthusiasm. Run the conditional logic honestly before committing capital.
An online store is worth launching if your product carries at least a 3:1 lifetime-value-to-CAC ratio — the minimum for sustainability cited in Shopify’s 2026 research — and if you can fund three to six months of operating costs before profitability. At an $80 CAC, that means each customer must generate roughly $240 in lifetime revenue, achievable in repeat-purchase categories like consumables but difficult for one-time big-ticket items.
It is not worth launching if you’re relying on a single paid channel with no organic or email backbone, because a 2:1 or lower LTV:CAC ratio leaves you break-even at best and one algorithm change from insolvency. Sellers in that position should either fix unit economics first — higher AOV, better retention — or reconsider the model entirely. If you’re weighing an online store against buying into an established system with built-in demand, the decision framework parallels the sale vs liquidation vs transfer exit costs analysis that governs any business you might one day want to leave cleanly. And if you’ll operate with a co-founder, settle ownership and roles in writing early to avoid the steep partnership dispute legal fees that sink otherwise-viable ventures.
Frequently Asked Questions
How much does it cost to start a Shopify store in 2026?
A lean Shopify store costs around $30–$70/month in fixed fees — the Basic plan at $39/month ($29 billed annually) plus a free theme and minimal apps — before processing fees of 2.9% + 30¢ per sale. Adding inventory, a premium theme, and paid ads pushes a realistic branded launch to $2,000–$10,000 in the first 90 days, per 2026 startup-cost data.
Is Amazon or Shopify cheaper for selling online?
Shopify is cheaper per sale for brands with repeat customers — its platform take runs roughly 3.5% versus Amazon’s stacked referral (default 15%) plus FBA fees that consume 30–45% of the sale price. Amazon’s advantage is built-in traffic and Prime eligibility, which Shopify doesn’t supply. Many sellers use both platforms for different strengths.
What are the hidden costs of running an online store?
The biggest overlooked costs are customer acquisition (averaging $68–$84 per customer in 2026, up 40% since 2023), paid apps ($200–$1,000/month for growing stores), payment processing on low-price items, and business insurance ($300–$800/year). Software is often under 15% of true first-year spend; inventory and marketing dominate the rest.
How much are payment processing fees for e-commerce?
Both Stripe and Shopify Payments charge 2.9% + 30¢ per online card sale on entry tiers — about $3.20 on a $100 order. That flat 30¢ hits small baskets hard, reaching a 5.9% effective rate on a $10 sale. ACH bank transfers cost far less at 0.8% capped at $5, per Stripe’s 2026 pricing verified July 8, 2026.
How We Researched This Article
Every platform, processing, and marketplace figure in this article was verified against primary rate documentation before publication. Subscription and card-rate figures for Shopify were confirmed against Shopify’s 2026 published U.S. pricing as reported by NerdWallet and StyleFactory Productions, both citing the platform’s official pricing page. Payment-processing rates were drawn from Stripe’s official pricing documentation, cross-referenced against multiple 2026 rate trackers, with the flat 2.9% + 30¢ domestic rate and ACH, Terminal, and dispute fees verified as current to July 8, 2026.
Amazon marketplace figures — the $39.99 Professional plan fee, the $0.99 Individual per-item fee, the 8–17% referral range, and the January 15, 2026 FBA fulfillment increase — were confirmed against seller-fee analyses from Feedvisor and Repricer, both citing Amazon’s official Seller Central announcements. Customer acquisition cost benchmarks were compiled from 2026 aggregated data reported by Ringly.io and Mobiloud, with vertical-level figures cross-checked against DTC benchmark reports.
Startup-cost ranges are modeled composites, not single-source point figures — they synthesize 2026 launch-cost breakdowns across several e-commerce cost analysts to produce defensible low and high bounds. Where provider-specific or period-specific point data was unavailable, we report ranges and label them as estimates rather than fabricating precision. All comparison-table math (per-sale fee modeling) is calculated by the author from the verified published rates and clearly marked as illustrative. Research was last conducted August 2026.
