Picking an e-commerce stack at $5K MRR is not the same problem as picking one at $500K MRR. The mistake most small stores make is buying the stack of a brand five stages ahead — too much tooling, too little revenue. Below: the categories that matter, the tools that actually deliver at each stage, and a decision matrix you can use today.

Core features your store actually needs
Before tool shopping, get clear on the basics. Your store needs four things that work without bolt-ons: a product catalog you can update without dev help, payments that don't fail at checkout, an inventory view that matches reality, and a way to run promos without creating spaghetti.
Skip anything that promises "all-in-one growth platform" — that's marketing for "expensive tool you'll outgrow in six months." Modular wins. Pick best-in-class per category and integrate.
Picking your platform
The platform decision compounds. Switching is painful — migrate when you have to, not when you want to.
Under $10K MRR: Shopify (Basic plan, $39/mo). Hosted, fast to launch, payments built in. Don't waste time on self-hosted at this stage.
$10K–$100K MRR: Shopify (Shopify or Advanced plan) or WooCommerce (WordPress) if you have dev resources and need deep customization. Webflow eCommerce works for design-heavy brands with small SKU counts.
$100K–$1M MRR: Shopify Plus (~$2.5K/mo) starts paying for itself with checkout customization and Shopify Functions. BigCommerce is a credible alternative — better for B2B-heavy ops.
$1M+ MRR: Magento (Adobe Commerce) for complex catalogs. Otherwise stay on Shopify Plus and stack headless if you need a custom storefront (Hydrogen, Next.js).
Squarespace and Wix Stores are fine for hobby tier — once you cross $5K MRR they're a tax.
Marketing tools that move revenue
Email and SMS still drive 25-40% of e-commerce revenue for stores that take them seriously.
Email: Klaviyo wins above $5K MRR — segmentation, flows and Shopify integration are best-in-class (~$45/mo at 1K contacts, scales hard). Mailchimp is fine below that, but you'll outgrow it.
SMS: Postscript or Attentive in the US (compliance handled). Outside US, Klaviyo SMS works in most markets.
Reviews: Trustpilot for brand trust signals, Yotpo or Loox for product reviews on PDPs, Judge.me for the budget option ($15/mo).
Ads: Meta Ads Manager and Google Ads remain the workhorses. TikTok for younger demos, Pinterest for visual products. Don't outsource campaign setup to "growth agencies" charging 20% of spend until you're past $50K/mo ad spend.
Content: Long-form blog content still drives organic traffic — but only if you commit to 12+ months. Treat SEO as compounding asset, not quick win.
Analytics: knowing what your customers do
GA4 is the default and free — set it up properly with enhanced ecommerce events from day one. Skip it and you'll regret it in month six when you can't answer "where did this revenue come from?"
Lightweight alternatives: Plausible or Fathom ($14-19/mo) for privacy-friendly tracking. Less feature-rich but no cookie banner needed in the EU.
Product analytics: Mixpanel or Amplitude once you have funnels worth optimizing (usually $50K+ MRR). Both have free tiers that work for smaller stores.
Session replay & heatmaps: Microsoft Clarity (free, surprisingly good) or Hotjar ($32/mo). Watch 20 sessions a week — you'll find conversion blockers your dashboards miss.
Customer support analytics: Tools like Gorgias and Zendesk give you ticket data tied to customer LTV. Useful from $20K MRR.
Payments: not just Stripe vs PayPal
Payment failure is silent revenue death. Pick a stack that minimizes friction at checkout.
Default: Stripe for cards globally. Best developer experience, transparent pricing (~2.9% + 30¢ in US), strong fraud detection.
Add PayPal: Roughly 15-25% of US/EU buyers prefer it. Skipping PayPal costs you sales — uncomfortable but true.
Wallets: Apple Pay, Google Pay, Shop Pay if on Shopify. One-click checkout converts dramatically better on mobile.
BNPL: Affirm, Klarna, Afterpay — adds 10-20% AOV in target categories (apparel, beauty, furniture). Fees are higher but offset by lift.
B2B: Stripe Invoicing, Resolve, or Apruve for net terms. Skip if you're pure DTC.
Ops & fulfillment: ShipStation ($10/mo+) for label printing and multi-channel orders. ShipBob or Easyship for 3PL fulfillment once you cross 100 orders/day. Linnworks or Brightpearl for inventory across multiple sales channels — only worth it from $50K MRR up.
The right answer at $5K MRR is "as little tooling as possible." The right answer at $500K MRR is "best-in-class per category, integrated tightly." Most stores get this backwards — they buy the stack of brands five stages ahead and burn cash.
