Picking an ecommerce platform is a five-year decision disguised as a two-week research task. Most stores don't fail because of bad marketing. They fail because they picked a platform that couldn't handle their actual growth, or paid for capability they never needed.
Here's how to make this decision properly, without getting talked into whatever platform your developer prefers building on.
Before comparing platforms, answer three questions honestly:
1. How many SKUs will you carry in year two, not month one?
2. How much do you need to customize the buying experience?
3. What's your realistic budget for year one, including the platform, development, and ongoing maintenance?
These three answers eliminate most of the guesswork below.
Hosted platforms (Shopify, BigCommerce)
You rent the infrastructure. The platform handles hosting, security patches, and PCI compliance for you. Setup is fast, usually 4-8 weeks for a standard store, and monthly costs run $29-$400+ depending on plan tier, before transaction fees and app costs.
This is the right call for most stores under 1,000 SKUs that don't need deep custom logic. The trade-off is less control: you're building within the platform's rules, and heavy customization means paying for third-party apps that pile up monthly fees fast. A store running 15-20 apps on Shopify can easily add $500-$1,500 a month on top of the base plan.
Open-source, self-hosted (WooCommerce, Magento Open Source)
You own the code and the hosting. WooCommerce runs on WordPress and is the lower-cost, lower-complexity option here, good for stores that want content and commerce tightly integrated (a blog-driven or content-heavy brand, for instance). Magento Open Source (now Adobe Commerce's free tier) handles far larger catalogs and more complex B2B logic, but needs a developer to maintain it properly. Neither has a licensing fee, but you're paying for hosting, security, and developer time instead.
Budget for WooCommerce builds typically runs $8,000-$25,000 for a mid-complexity store, plus ongoing hosting and maintenance. Magento builds start higher, often $25,000-$80,000+, because the platform is heavier and needs more specialized development.
If WooCommerce is the direction you're leaning, hire for the platform specifically. Plugin conflicts and checkout performance issues on WordPress are common, and a team that specializes in WooCommerce and WordPress development will catch problems a generalist web developer won't.
Headless / custom commerce
The storefront and the backend are decoupled, letting you build a fully custom frontend (in React or another framework) on top of a commerce engine handling inventory, payments, and orders. This is the right call when you need something no off-the-shelf theme can do: a highly branded shopping experience, multi-channel selling (web, app, in-store POS, marketplaces) from one inventory source, or extremely high traffic that standard platforms struggle to scale for.
Cost and timeline are both significantly higher, often $50,000-$150,000+ and 4-6 months for a full build, because you're essentially building custom software rather than configuring a template. This only pays off when the customization is actually driving revenue, not just aesthetic preference.
Because a headless build is closer to custom software development than a platform configuration, the same criteria for choosing any custom software development company apply when picking who builds it, not just the usual ecommerce agency checklist.
Catalog size and complexity. Under 500 SKUs with straightforward variants: hosted platforms handle this well. Thousands of SKUs, complex variant matrices, or multi-warehouse inventory: lean toward Magento or a headless build.
B2B vs. B2C. B2C stores are well served by Shopify or WooCommerce. B2B stores with tiered pricing, quote workflows, or purchase order billing usually outgrow hosted platforms fast and need either Magento's B2B extensions or a custom build.
International sales. Multi-currency, multi-language, and region-specific tax handling are stronger out of the box on BigCommerce and Magento than on base Shopify, though Shopify Markets has closed much of that gap.
Team capability. If you don't have an in-house developer and don't plan to hire one, a hosted platform is the realistic choice regardless of what else fits, because self-hosted platforms need ongoing technical maintenance that someone has to own.
Growth trajectory. If you're building for a specific, near-term scale event, a funding round, a national retail rollout, a major marketing push, plan the platform around where you'll be in 18 months, not where you are today. Migrating platforms mid-growth is expensive and risky; it's cheaper to slightly over-build now than to replatform during your busiest quarter.
If you're not confident in that 18-month picture yet, don't guess. An MVP-first approach lets you launch a scoped store, confirm real demand, and make the bigger platform call with actual sales data instead of a forecast.
A lot of stores start on Shopify, hit a wall around 2,000-3,000 SKUs or a complex B2B requirement, and then face a costly replatforming project. This isn't a failure of Shopify, it's a failure of not sizing the decision to year-two reality during initial planning.
If there's a real chance you'll need Magento-level complexity or a headless build within 18-24 months, it's often cheaper to build there from the start than to migrate later. Migration projects run 30-50% more expensive than a comparable greenfield build, because you're also handling data migration, redirect mapping, and SEO preservation on top of the build itself.
The platform decision isn't just about launch cost. Hosted platforms bundle security and updates into the subscription. Self-hosted platforms need someone actively maintaining plugin updates, security patches, and server performance, or you're exposed to the same vulnerabilities that hit outdated WordPress sites regularly.
Budget for ongoing maintenance as a real line item: typically 15-20% of the initial build cost annually for self-hosted platforms, less for hosted platforms since that's baked into the subscription fee.
The platform sets your ceiling. The development partner determines whether you actually reach it. A rushed Shopify build and a rushed Magento build both fail the same way: slow load times, broken checkout flows, and a site that looks fine in a demo but breaks under real customer traffic. Ask for load-time benchmarks on stores they've shipped, ask how they handle post-launch support, and get a clear scope document before development starts, not a verbal agreement.
If you'd rather work with a full-service website development company in India that can advise on the platform decision itself rather than just execute whatever you've already chosen, bring them in before you finalize the platform, not after.
Don't pick a platform because it's what your developer knows best or what a competitor uses. Size the decision to your actual catalog, customization needs, and 18-month growth plan. Hosted platforms win on speed and low maintenance. Self-hosted and headless win on control and scale, at a real cost in budget and complexity. Get this decision right up front, because replatforming later costs more than building right the first time.
If you want a second opinion on which platform fits your specific catalog and growth plan, that's worth a short conversation before you commit budget.
