How Much Does It Cost to Build an Online Store in 2026?

The build itself costs little: $500 to $2,000 in year-one software on a DIY builder or AI platform, or $5,000 to $50,000 with an agency. The full first year, with ads, inventory, and processing, typically lands between about $1,300 and $68,000 depending on the path you pick.

This is a SoGood post. SoGood.ai is an AI operator that builds and runs physical-product stores, so we sell one of the three paths compared below. Every range in this article is an industry figure, not our price list, and we have flagged the costs that no tool, ours included, can remove.

Every line item in the cost of an online store

Most cost guides quote the platform fee and stop. That number is real, but it is one of the smallest checks you will write. Seven line items cover nearly everything an online store costs in year one.

Two things to notice before the detail. First, only two of the seven lines are one-time costs; everything else recurs, which is why year-one totals beat launch quotes as a planning number. Second, the bottom three rows are identical on every path, because no builder, agency, or AI tool sells products for free or runs ads for free.

Domain: $10 to $20 a year

A .com from a mainstream registrar runs $10 to $20 a year. Buy it yourself, in your own account, even if someone else builds the store; owning the domain is what keeps every other decision reversible.

Platform or build: the number everyone budgets for

On the DIY path, Shopify Basic costs around $39 a month, and competing builders sit in the same $29 to $79 band. If even that monthly fee grates, there are Shopify alternatives with no monthly fee, though most trade the fee for higher per-sale costs.

An agency build for a small ecommerce brand typically runs $5,000 to $50,000 one-time, depending on custom design and integrations. AI operator platforms sit near DIY pricing, roughly $20 to $100 a month as an industry range; SoGood itself is a software subscription that includes the build.

Theme and apps: the quiet creep

The base platform rarely stays base. A paid theme is $0 to $350 one-time, then reviews, email, bundles, and loyalty apps add $10 to $50 a month each, and a $39 store quietly becomes a $150 store. That creep is deliberate; it is how software vendors price, and it is worth a periodic subscription audit.

Payment processing: the fee no path removes

Card processing costs around 2.9% plus $0.30 per transaction at standard Stripe or platform rates. On $30,000 of first-year sales that is roughly $900. Budget it as a percentage of revenue, because no builder, agency, or AI tool makes it go away.

Products and inventory: the first real money

A first inventory order for a small physical-product brand typically costs $500 to $5,000, and what you sell drives that number more than where you sell it. Picking products worth selling is a bigger cost decision than picking a platform.

Dropshipping cuts the upfront stock bill to zero, but you pay for it per order in supplier margin. If cash is the constraint, starting without inventory is a legitimate year-one move; just treat it as deferred cost, not free.

Ads: the biggest recurring line

Plan on $300 to $3,000 a month if you want strangers to find the store. The first few months are partly tuition: you pay to learn which creative and audiences convert. AI marketing tools stretch the budget by making each test cheaper, but the spend itself stays.

Your labor: the biggest hidden line

Fifteen hours a week at $25 an hour is more than $18,000 a year of unpaid work. Most "cheap" stores are expensive stores paid for in evenings and weekends. If you would run that math when budgeting AI cost per employee, do not skip it for yourself.

The build is the small number

In a typical $11,000 first year, the domain, theme, platform, and apps together cost about $1,300, roughly 12% of cash spend. Ads and inventory take about $9,000, and your own labor is worth more than every cash line combined.

The practical implication: haggling over a $10 difference in platform fees optimizes the wrong line. The levers that actually move your total are ad efficiency, inventory bets, and how many operating hours you can take off your own calendar.

DIY vs agency vs AI operator: the same bills, split differently

This is the budget half of a decision we examined in do you still need an ecommerce website agency. All three paths pay the same domain, processing, inventory, and ad bills. What changes is the build fee, the subscription stack, and whose hours run the store.

The agency path front-loads the cost and keeps charging: a $12,000 build plus a $1,500 monthly retainer is $30,000 in year one before a single ad runs. That retainer line is exactly what founders mean when they say they fired their marketing agency.

An AI operator collapses the build fee and several tool subscriptions into one bill and takes a real share of the operating hours: storefront, sourcing legwork, ad drafts, email, social, and CRM. Be clear about what it does not do; it will not out-polish a good agency, and it removes zero dollars of ad spend or inventory. The walk-through of starting an online store with AI shows where those hours actually go.

Year one at three budgets

Ranges are honest but hard to plan with, so here are three concrete year-one scenarios. Each one excludes the value of your own hours, which is the quiet subsidy behind every low number. The spread between them comes almost entirely from ads, inventory, and who does the work, not from the platform fee.

Low, around $1,300: a dropshipping store on a DIY builder with a small ad budget. It is a real way to start and a fragile one; dropshipping margins are thin because a supplier gets paid on every order, and $700 of yearly ad spend is too little to learn quickly.

Typical, around $11,000: a small stocked brand on DIY or AI-operator software, with roughly $3,000 in inventory and $500 a month in ads. This is where most serious first years land, and note that under $1,500 of it is the build.

High, around $68,000: an agency build with a retainer, $10,000 of stock, and $2,000 a month in ads. You are buying polish and other people's hours; the store is not meaningfully more expensive to run, you have simply hired out the running.

Cheap to start is not cheap to run

Launch cost and run cost are different questions, and most guides only answer the first. A store that works gets more expensive: winning products need restocking, working ads earn bigger budgets, and processing fees grow with every sale. Only the platform fee stays flat.

Walk the typical store through its own year to see it. Month one costs about $600: platform, theme, domain, and a first small ad test. Month twelve, with the store working, costs about $1,400: the same $40 of software, plus $700 in ads that are now earning their keep, a $500 restock, and processing on real sales. The store got healthier and the bill went up; that is what success costs.

So budget the year, not the launch. A useful rule: whatever your build and software cost, expect the running of the store, in ads, stock, and hours, to cost three to five times that in year one. If that multiple worries you, shrink the inventory bet or the ad budget, not the theme.

Where you can cut safely, and where you cannot

Safe cuts live in the software column. Start on a free theme, skip every app until a specific problem demands one, and hold the app stack under $50 a month for the first six months. None of that slows the business down, because customers never see your admin panel.

Unsafe cuts live in the demand column. Cutting the ad budget below a few hundred dollars a month does not save money; it just stretches the learning phase across more months of platform fees. Underordering a winning product to save cash converts your best seller into an out-of-stock page.

The one cut that looks safe and is not: your own time. Doing every job yourself works until the hours run out, and for most founders they run out around the same week the store starts working. Decide in advance which jobs you will hand off, and to whom or to what, before that week arrives.

The bottom line for your budget

Three questions pick your path. If you have hours but not cash, DIY is the honest choice: under $2,000 of software and a lot of your evenings. If you have cash and want polish plus a human team, an agency runs $30,000 or more in year one and earns it on brand-critical builds. If you want most of the operating hours handled without agency pricing, an AI operator is a software subscription that covers build and operations, while ads, stock, and processing stay at full price.

Whichever you choose, write the budget in this order: labor, ads, inventory, processing, then software. That is the order the money actually leaves in, and it is the order almost every cost guide gets backwards.
