How Much Does a BigCommerce Store Cost to Build and Run?

"What's this going to cost us" is usually the second question in a discovery call, right after "can you do this." For BigCommerce specifically, the honest answer has more moving parts than a single number, because the platform fee, the build cost, and the ongoing running cost behave very differently from each other. This post breaks down each piece with real ranges so you can budget accurately instead of guessing.

The Platform Fee, and the Threshold Trap

BigCommerce's plan pricing looks simple until you notice the fine print about annual online sales. As of this writing, the tiers run roughly like this:

Plan	Monthly Cost	Annual Sales Threshold
Standard	~$39/mo	up to $50,000
Plus	~$105/mo	up to $180,000
Pro	~$399/mo	up to $400,000
Enterprise	custom pricing	no cap

Once a store crosses its plan's threshold, BigCommerce moves the account to the next tier automatically, regardless of whether the merchant needed any new features. This is the single most common budgeting mistake we see: a business plans around the Plus plan's $105 monthly fee, has a strong holiday season, crosses $180,000 in trailing annual sales, and gets bumped to Pro at nearly four times the monthly cost. Model your expected revenue growth against these thresholds before committing to a plan, and build the next tier's cost into your year-two projections.

Build Costs: What You Actually Pay to Launch

Build cost depends almost entirely on how much customization the storefront needs. We break it into three tiers based on real project ranges.

Theme Licensing Costs

Before you get to labor, factor in the theme itself. BigCommerce's free themes are usable but limited in layout variety, while premium Stencil themes from the marketplace or third-party theme shops typically run $150 to $350 as a one-time license fee. A small number of premium themes come with more advanced built-in modules (mega menus, lookbooks) that push the price closer to $500. This is a small line item compared to labor, but it is worth budgeting separately since some agencies quote it apart from build hours.

Template Setup ($2,000 to $6,000)

This covers taking a purchased or free Stencil theme, applying your branding, configuring products and categories, setting up basic apps (reviews, email capture, shipping rules), and launching. It suits a straightforward catalog under a few hundred SKUs with no unusual business logic. Timeline is typically 3 to 5 weeks.

Custom Theme Development ($8,000 to $30,000)

This is a theme built or heavily modified from scratch to match a specific brand and UX requirements: custom product page layouts, bespoke filtering, unique merchandising modules, and integrations with tools like Klaviyo or a loyalty platform. Most mid-market brands doing a serious rebrand or migration land in this range. Timeline runs 6 to 12 weeks depending on integration count.

Headless Build ($30,000 to $120,000)

A fully decoupled storefront, typically Next.js on the frontend consuming BigCommerce's GraphQL Storefront API (often through the Catalyst framework), with custom checkout flows, advanced personalization, and multi-storefront or B2B logic. This tier is for businesses where storefront performance, design control, or system integration complexity justifies the investment. Timeline is 3 to 6 months, and the number of ERP, PIM, or third-party integrations is usually the biggest cost driver within this range, more than the frontend design itself.

Our team scopes each project individually through BigCommerce development engagements, since the honest cost driver is almost always integration complexity, not visual design.

What You Will Pay Every Month After Launch

App Subscriptions

Because BigCommerce ships more native functionality than Shopify, a typical store runs fewer paid apps, often 4 to 8 rather than 15 or more. Still, expect real costs for reviews (around $15 to $60/mo), email marketing beyond the basics (Klaviyo scales with list size, often $50 to $500+/mo), loyalty or subscriptions ($50 to $300/mo), and advanced search or filtering on larger catalogs ($50 to $200/mo). A reasonable mid-market app stack lands between $250 and $900 a month.

Payment Processing

BigCommerce charges no platform transaction fee, so your only cost here is your payment gateway's standard processing rate, typically 2.6 percent to 2.9 percent plus 30 cents per transaction through providers like Stripe, PayPal, or Authorize.net. This is where BigCommerce quietly saves money compared to platforms that layer an additional fee on top of gateway costs; on a $1 million revenue store, avoiding even a 1 percent stacked fee is $10,000 a year.

Ongoing Support and Maintenance

Most stores retain a developer or agency for updates, seasonal changes, bug fixes, and small feature additions. Retainers we typically see range from $500 a month for light, occasional support to $3,000 to $8,000 a month for stores running frequent promotions, integrations, and active feature development. Skipping this entirely is a false economy for anything beyond a very small store; theme and API changes happen, and an unmaintained store degrades in subtle ways (broken tracking pixels, outdated shipping rules) that are expensive to untangle later.

A Three Year Total Cost of Ownership Example

Consider a mid-market apparel brand launching with a custom theme build, starting on the Plus plan, and growing from $150,000 to $600,000 in annual revenue over three years.

Year one: Custom theme build ($18,000), Plus plan for 12 months ($1,260), app stack averaging $400/mo ($4,800), light support retainer ($500/mo, $6,000), payment processing at 2.9 percent on $150,000 (~$4,350). Year one total: roughly $34,400.

Year two: Revenue crosses the Plus threshold mid-year, so plan cost blends toward Pro ($3,000 for the year), app stack grows to $600/mo ($7,200), support retainer increases to $1,500/mo ($18,000) as promotional activity ramps up, processing on $350,000 ($10,150). Year two total: roughly $38,350.

Year three: Pro plan for the full year ($4,800), app stack at $750/mo ($9,000), support retainer at $2,000/mo ($24,000) with a mid-year feature project added ($8,000), processing on $600,000 ($17,400). Year three total: roughly $63,200.

Three year total: approximately $136,000, or an effective run rate that grows from roughly 23 percent of year-one revenue down to about 11 percent of year-three revenue as fixed build costs amortize against a larger sales base. Your numbers will move depending on app choices and how much custom development you commission along the way, but this shape (front-loaded build cost, steadily rising operating cost tied to growth) is typical.

Where BigCommerce Saves You Money

1. No platform transaction fee, regardless of payment gateway, which is a direct and compounding saving as revenue grows.
2. More native features (product options, B2B tools, multi-channel selling) mean fewer paid apps than a comparable Shopify build, which reduces both subscription cost and the integration risk of stacking many third-party tools.
3. Included staging environments and stronger native API limits reduce the custom development sometimes needed on other platforms just to build a safe deployment workflow.

Where Costs Sneak Up

• Revenue threshold plan jumps, as covered above, catch merchants who budget only for their current tier.
• App costs that scale with volume, particularly email marketing platforms and some review tools, can quietly double as your list or order count grows.
• Support retainers that start too small. A $300/mo retainer covers almost nothing once you are running regular promotions, and emergency fixes billed hourly outside a retainer cost more than the retainer would have.
• Headless and integration scope creep. ERP and PIM integrations routinely take longer than estimated because the third-party system's API documentation is incomplete or its data is messier than expected; budget a contingency of 15 to 20 percent on any integration-heavy project.

If you compare this against a Shopify or WooCommerce build for the same catalog, the numbers often land within striking distance of each other for a straightforward store, but diverge meaningfully once transaction fees and app counts are factored in for larger catalogs. We also build on those platforms through our ecommerce development services, so we can give you a real comparison rather than a platform-biased one.

FAQ

Does BigCommerce charge extra for using my own payment gateway?

No. Unlike some competing platforms, BigCommerce does not add a transaction fee on top of your payment processor's standard rate, no matter which gateway you use.

How much should I budget for a first-year BigCommerce build as a small business?

A straightforward template-based launch typically runs $2,000 to $6,000 in build cost plus the Standard plan fee, app subscriptions of $100 to $300 a month, and a light support arrangement. Total first-year cost for a small catalog is often $10,000 to $20,000 including operating costs.

Is a headless BigCommerce build worth it for a smaller store?

Usually not. Headless makes sense when you need storefront performance at scale, deep system integrations, or highly custom UX that a Stencil theme cannot deliver. For most stores under $2 million in revenue, a well-built custom theme delivers similar results for a fraction of the cost.

Will my monthly costs go down after the initial build?

Somewhat, but expect them to rise over time as revenue grows, since plan tier, app usage, and support needs generally scale with order volume rather than staying flat.
