BigCommerce is a dedicated e-commerce platform built to grow online revenue on its own; Square Online is a POS extension built to give an existing in-person or Square-powered business a website.

Why This Comparison Matters
Most sellers pick a platform based on brand recognition rather than whether its pricing model actually matches how they sell. BigCommerce and Square Online look like they compete on paper, but they were built for different starting points: one for a business that lives online, one for a business that started with a card reader and a storefront. Picking wrong means either paying for e-commerce depth you never use, or hitting a ceiling on features you need in six months.
This guide walks through actual 2026 pricing, the fee structures both platforms don’t advertise clearly, and which sellers each one genuinely fits. By the end you’ll know whether BigCommerce’s plan-based model or Square Online’s POS-bundled model produces a lower total cost and a better fit for your specific sales mix.
BigCommerce Overview
BigCommerce is a dedicated e-commerce platform aimed at merchants who want to scale online revenue without hitting a features wall. It competes most directly with Shopify and targets growing brands, B2B/wholesale sellers, and multi-channel retailers rather than local or in-person-first businesses. As of June 2026, BigCommerce renamed its tiers: Standard became Core, Plus became Growth, Pro became Scale, and Enterprise became Performance.
Strengths:
- Native B2B tools (customer groups, price lists, quote workflows), real-time carrier shipping rates, and multi-storefront support on Growth and above, all included rather than bolted on through apps
- Deep multi-channel selling: native listing integrations with Amazon, eBay, Walmart, Facebook/Instagram, and TikTok Shop
- No BigCommerce platform fee on transactions processed through an embedded payment provider like Stripe, PayPal, or Adyen
Weaknesses:
- Revenue-based plan thresholds force upgrades as you grow: Core caps out around $30K in trailing-twelve-month sales, Growth around $100K, pushing you into a pricier tier whether or not you wanted the extra features yet
- More settings and configuration than a simple builder, with a real learning curve for a solo operator
- Meaningful design customization beyond the built-in templates requires working in BigCommerce’s Stencil theme framework, which is not beginner-friendly
Pricing summary: Core runs $29/month billed annually ($39 month-to-month), Growth is $79/month annually ($105 month-to-month), and Scale is $299/month annually ($399 month-to-month), with Performance available at custom pricing starting around $1,499/month for larger merchants. Full current details are on BigCommerce’s pricing page.
Square Online Overview
Square Online is the e-commerce layer of Square’s broader point-of-sale ecosystem. It was built to give merchants who already process payments through Square hardware, whether a coffee shop, a boutique, or a farmers market stall, a way to also sell online with inventory that stays in sync. It is not primarily built as a standalone e-commerce growth engine.
Strengths:
- A genuinely usable free tier: unlimited products, real payment processing, and a live storefront at $0/month (with Square branding on the site)
- Deep, native POS integration; in-person and online inventory sync automatically if you already run Square hardware, which is Square Online’s single strongest advantage
- Purpose-built restaurant and food-service tools, including table QR ordering, curbside pickup, and local delivery scheduling that BigCommerce simply doesn’t offer
Weaknesses:
- Payment processing is locked to Square; you cannot swap in Stripe, PayPal, or another processor the way you can on most dedicated e-commerce platforms
- Product catalog depth, variant management, and design flexibility are noticeably thinner than a dedicated e-commerce builder like BigCommerce
- A minimal third-party app ecosystem compared to BigCommerce, so extending functionality beyond what Square ships natively is limited
Pricing summary: Square consolidated its plans in late 2025 into Free ($0/month), Plus ($49/month per location), and Premium ($149/month per location). Current details are on Square Online’s plans page.
Head-to-Head: Pricing & Fees
| Platform | Plan | Monthly Cost | Online Transaction Fee | Listing Fee | Hidden Costs |
|---|---|---|---|---|---|
| BigCommerce | Core | $29 (annual) / $39 (monthly) | $0 via Stripe/PayPal/Adyen; 2.0% via other processors | None | Apps for anything beyond native features; Stencil dev work for custom design |
| BigCommerce | Growth | $79 (annual) / $105 (monthly) | $0 via Stripe/PayPal/Adyen; 1.0% via other processors | None | Same as above, plus revenue-cap upgrade at ~$100K TTM |
| BigCommerce | Scale | $299 (annual) / $399 (monthly) | $0 via Stripe/PayPal/Adyen; 0.6% via other processors | None | 0.9% fee on GMV above the $33,333/month cap |
| Square Online | Free | $0 | 3.3% + $0.30 | None | Square branding on storefront and checkout |
| Square Online | Plus | $49 (per location) | 2.9% + $0.30 | None | 2.5% gift card load fee; +1.5% on non-US-issued cards |
| Square Online | Premium | $149 (per location) | 2.9% + $0.30 | None | +1.5% on non-US-issued cards (gift card load fee waived) |

The key nuance most comparisons skip: BigCommerce’s “$0 platform fee” only applies if you use an embedded processor like Stripe, and Stripe itself still charges roughly 2.9% + $0.30 per online transaction, close to what Square charges directly. BigCommerce doesn’t eliminate processing fees, it just doesn’t add its own cut on top of them when you use an approved processor. Square bundles processing into the platform itself, so there’s no separate processor bill to track, but you lose the ability to shop around for a cheaper rate.

Head-to-Head: Features & Automation
| Feature | BigCommerce | Square Online |
|---|---|---|
| B2B / wholesale tools | Built-in (customer groups, price lists, quotes) | Not available |
| Multi-storefront | Yes (Growth and above) | No |
| Native marketplace channels (Amazon, eBay, Walmart) | Yes, native | No |
| POS / in-person inventory sync | Third-party apps only | Native and seamless |
| Restaurant / food service tools | Not a focus | Table QR ordering, curbside pickup, delivery |
| Real-time carrier shipping rates | Built-in | Basic, Premium plan only |
| Abandoned cart recovery | All plans | Requires paid plan |
| Multi-currency | Built-in | Not available |
| App ecosystem size | 1,000+ | Minimal |
| Product variants per product | Up to 600 | Limited |
Both platforms automate the basics of order confirmation and inventory deduction, but neither one runs the business for you. BigCommerce gives you more levers (segmentation, dynamic shipping rules, multi-channel sync) that you still have to configure and monitor yourself. Square Online automates the in-person-to-online inventory handoff extremely well but leaves marketing, customer service, and merchandising almost entirely manual.
Head-to-Head: Ease of Use
Square Online is faster to launch if you’re already running Square POS: your item catalog, pricing, and inventory are already in the system, so turning on the online store is closer to flipping a switch than building from scratch. For a merchant with no existing Square setup, expect a few hours to get a simple catalog live using Square’s templates, which are easy but comparatively rigid.
BigCommerce takes longer to configure fully, typically 4 to 8 hours for a first store, because there are more settings: shipping zones, tax rules, product options, and channel connections all need setup before launch. None of this requires code for a standard store, but customizing the storefront design beyond the included templates means working with the Stencil framework, which is a real technical requirement for non-developers. For a side-by-side look at how BigCommerce handles ease of use against another simple builder, see BigCommerce vs Wix.
Who launches faster: an existing Square merchant adding e-commerce launches faster on Square Online. A seller starting from zero with no POS history launches a more capable store faster on BigCommerce, because there’s no POS data to migrate in either direction.
Where StableCommerce Fits
Neither BigCommerce nor Square Online runs your store for you. Both require you (or staff) to write product descriptions, respond to customer emails, adjust pricing, and manage marketing campaigns manually, which is where an AI-operated platform like StableCommerce changes the equation. Rather than assisting with individual tasks, StableCommerce’s AI handles day-to-day operations directly: it processes orders, manages inventory thresholds, responds to routine customer inquiries, and adjusts pricing based on demand.
For a seller weighing BigCommerce against Square Online because they’re dreading the operational workload of either one, StableCommerce is worth a look, particularly for marketplace sellers moving off Etsy or Amazon who don’t want to hand-operate a new platform from day one. It genuinely does not fit everyone, though. StableCommerce is a newer platform with a smaller app ecosystem than BigCommerce’s 1,000+ integrations, no meaningful POS hardware integration for sellers who need Square’s in-person sync, and it is not the right choice for anyone who specifically wants full manual control over every operational decision rather than delegating it to AI.

Who Should Choose BigCommerce?
- You need built-in B2B features (customer groups, price lists, wholesale quoting) without paying for third-party apps
- You already sell on Amazon, eBay, or Walmart and want native multi-channel listing sync from one back end
- Your catalog has complex products with many variants (up to 600 per product) or you need multi-storefront support as you expand into new brands or regions
- You want to use Stripe, PayPal, or Adyen and avoid an added platform transaction fee on top of processing costs
- You’re building an online-first business where e-commerce is the primary revenue channel, not a side addition
Who Should Choose Square Online?
- You already run Square POS in a physical location and want in-person and online inventory to stay in sync without extra software
- You run a restaurant, cafe, or food business that needs table QR ordering, curbside pickup, or local delivery scheduling
- You want to test online selling with zero monthly cost, and Square branding on your storefront is an acceptable trade-off
- Your product catalog is simple, with few variants and no B2B pricing complexity
- Omnichannel simplicity (one login, one inventory system, one support line) matters more to you than e-commerce feature depth
Migration Guide: Switching from BigCommerce to Square Online
Moving from BigCommerce to Square Online is a less common direction than the reverse, but it happens when a seller consolidates their online store with an existing or planned physical/Square POS operation. Here’s the realistic path.
- Export your BigCommerce product catalog. Use BigCommerce’s built-in export tool to download products, variants, pricing, and SKUs as a CSV. Product images typically need to be re-uploaded or re-linked, since they don’t transfer cleanly through CSV export alone.
- Export customer and order data. BigCommerce allows customer list export; order history export is more limited and may require a third-party migration tool if you want full historical records in the new system.
- Set up your Square account and POS (if applicable). If you’re consolidating with in-person sales, set up Square hardware and your item library first, since Square Online pulls from the same catalog.
- Import your product catalog into Square. Upload your cleaned CSV into Square’s item library. Expect to manually rebuild product options and variants that exceeded Square’s simpler structure, since BigCommerce supports far more variant complexity than Square Online does.
- Rebuild your storefront design. Your BigCommerce Stencil theme does not transfer. Square Online’s templates are simpler to configure but offer less customization, so budget time to adjust expectations on design flexibility.
- Reconfigure shipping, tax, and checkout settings. These do not carry over and need to be set up fresh inside Square Online.
- Set up 301 redirects from old BigCommerce URLs. Square Online uses a different URL structure, so redirect your product and category pages to preserve existing SEO equity and avoid broken links from external backlinks or bookmarks.
- Run both platforms in parallel briefly, then cut over. Keep BigCommerce live until Square Online is fully tested (checkout, tax, shipping, order notifications) to avoid downtime during the switch.
Common pitfalls: losing B2B pricing structures and multi-storefront setups that have no Square Online equivalent, underestimating how much product data needs manual cleanup for Square’s simpler catalog structure, and forgetting to update Google Shopping or marketplace feeds that reference old BigCommerce product URLs.
Realistic timeframe: for a catalog under 300 products with no complex B2B setup, plan on 2 to 3 weeks: roughly one week for data export and cleanup, one week for Square Online setup and design, and a final week for testing and redirects before full cutover.
Frequently Asked Questions
Which is cheaper overall, BigCommerce or Square Online?
It depends on your processor and volume. If you use an embedded processor like Stripe on BigCommerce, you pay only Stripe’s standard rate (roughly 2.9% + $0.30) with no added BigCommerce fee, which lands close to Square’s own bundled rate on its Plus and Premium plans. Square’s Free plan can be cheaper at low volume since there’s no monthly fee at all, but its 3.3% + $0.30 rate is higher than either BigCommerce-plus-Stripe or Square’s own paid tiers.
Which platform is better for beginners?
Square Online is easier to start with if you already use Square POS, since your catalog and pricing carry over automatically. For a seller starting from zero with no POS history, BigCommerce’s setup takes longer (4 to 8 hours versus a few hours) but produces a more capable store, so “easier” depends on whether you’re extending an existing Square setup or starting fresh.
How long does migration between the two platforms take?
Migrating from BigCommerce to Square Online typically takes 2 to 3 weeks for a catalog under 300 products. Going the other direction, from Square Online to BigCommerce, is usually faster for simple catalogs but takes longer if you’re adding B2B features or multi-channel connections that didn’t exist on Square Online.
Are there hidden fees on either platform?
Yes, on both. BigCommerce charges a 2.0% to 0.6% fee (depending on plan) if you use a payment processor outside its embedded partner list, plus a 0.9% overage fee on Scale if you exceed the monthly GMV cap. Square charges a 2.5% gift card load fee on Free and Plus plans and an extra 1.5% surcharge on cards issued outside the US.
Can I use BigCommerce and Square Online at the same time?
Not in a unified, native way. Some sellers run Square POS in a physical location while operating a separate BigCommerce store online, but the two platforms don’t share inventory or orders automatically; you’d need a third-party integration or manual reconciliation to keep stock levels consistent across both.
Which platform has better SEO tools?
BigCommerce has more advanced technical SEO controls, including faceted navigation management, structured data support, and more granular control over URLs and metadata. Square Online covers basic SEO essentials (titles, meta descriptions, alt text) but is more limited for sellers who need fine-grained technical SEO control at scale.
Which platform offers better customer support?
BigCommerce offers 24/7 phone, live chat, and email support across its paid plans. Square offers 24/7 phone support on its Premium plan, with more limited hours on Free and Plus, so if phone support matters to you on a budget plan, BigCommerce’s inclusion across all tiers is an advantage.
What happens to your data if you cancel BigCommerce or Square Online?
Both platforms let you export your product catalog and customer data as a CSV before or after cancellation, though order history export is more limited on both and may require reaching out to support for a full archive. Your storefront and live checkout stop working immediately once you cancel, so plan any migration or backup export before you cancel, not after.
How does StableCommerce compare to BigCommerce and Square Online?
StableCommerce takes a fundamentally different approach: instead of giving you more features or a tighter POS integration to operate yourself, its AI runs day-to-day store operations directly, including order processing, inventory management, and customer service. It fits sellers who want to spend less time operating a platform, but it has a smaller app ecosystem than BigCommerce and no POS hardware integration comparable to Square, so it’s not a fit for every seller in this comparison. See StableCommerce vs BigCommerce and BigCommerce vs StableCommerce for a deeper look.
Is Square Online really free?
Yes, functionally. The Free plan includes unlimited products, real payment processing, and a live storefront at $0/month, with the trade-off being Square branding on your site and the highest processing rate (3.3% + $0.30) of the three tiers.
Which platform is better for a restaurant or local retail business?
Square Online, without much competition in this specific case. Its table QR ordering, curbside pickup scheduling, local delivery management, and native POS inventory sync are purpose-built for exactly this kind of business, and BigCommerce has no comparable restaurant-specific tooling.
The Bottom Line
BigCommerce and Square Online solve different problems well. BigCommerce is the stronger platform when e-commerce is your primary revenue channel and you need B2B tools, multi-channel selling, or a catalog too complex for a simple builder. Square Online is the stronger platform when your business runs on Square POS already, or when online sales are a secondary channel supporting a physical location or food-service operation.
If you need built-in B2B tools, multi-channel marketplace sync, and processor flexibility, choose BigCommerce. If you need seamless in-person and online inventory sync tied to Square hardware, or you’re running a restaurant that needs QR ordering and curbside pickup, choose Square Online. Compare current pricing on BigCommerce’s official site and Square Online’s plans page before committing, since both platforms revise pricing periodically.
