E-commerce Startup Stack Under $100/Month
You need a store, email marketing, analytics, and automation to launch an e-commerce brand. Most startups overspend on each category. Here's a complete stack for $67.59/month that covers everything you need from launch through your first $50K in revenue — every price verified against actual vendor pages.
The Complete E-commerce Stack
| Category | Tool | Plan | Monthly Cost |
|---|---|---|---|
| Store | Shopify | Basic | $39/mo |
| Email Marketing | Brevo | Starter | $9/mo |
| Analytics | Plausible | Starter | $9/mo |
| Automation | Make | Core | $10.59/mo |
| Total Monthly Cost | $67.59/mo | ||
Store: Shopify Basic ($39/mo)
Shopify Basic at $39/mogives you a full online store, 2 staff accounts, basic reports, and up to 77% shipping discounts. Shopify Payments eliminates the 2% transaction fee — use it unless you have a specific reason for another processor.
Hidden costs to watch:Paid apps average $20–$50/mo each. Premium themes run $180–$350 one-time. Start with a free theme and zero paid apps. Add apps only when you can measure their impact on revenue.
Why not WooCommerce?WooCommerce is free to install, but hosting ($7–$40+/mo), security patches, plugin conflicts, and maintenance time add up. For a startup focused on selling — not managing infrastructure — Shopify's managed experience is worth $39/mo.
Email Marketing: Brevo Starter ($9/mo)
Brevo Starter at $9/mo gives you 5,000 emails/month with no daily limit and basic reporting. The key advantage: Brevo charges by emails sent, not contacts stored. You can have 100,000 contacts on the free plan. Starter removes the 300 emails/day cap.
Why not Mailchimp?Mailchimp Free limits you to 250 contacts and 500 sends/month. Mailchimp Essentials ($13/mo at 500 contacts) gets expensive fast as your list grows because Mailchimp charges per contact. Brevo's contact-unlimited model is fundamentally better for e-commerce stores building large customer lists.
Analytics: Plausible Starter ($9/mo)
Plausible Starter at $9/mogives you privacy-friendly analytics for 1 site with 10K pageviews/month, 3-year data retention, and email/Slack reports. The script is under 1KB — it won't slow your store. No cookies means no consent banner needed for GDPR compliance.
Why not Google Analytics? GA4 is free but complex to set up correctly, requires a cookie consent banner, and the interface is overwhelming for e-commerce founders who need quick answers. Plausible gives you traffic sources, top pages, and conversion tracking in a single dashboard.
Automation: Make Core ($10.59/mo)
Make Core at $10.59/mo gives you 10,000 operations/month with unlimited scenarios. Use it to sync new Shopify orders to Brevo, auto-tag customers by product type, send review requests 14 days post-purchase, and update inventory in Google Sheets.
Why Make over Zapier?Zapier Professional costs $29.99/mo for only 750 tasks. Make Core gives you 10,000 operations for $10.59/mo — roughly 13x more volume per dollar. The visual builder takes slightly longer to learn, but the cost savings compound monthly.
What to Skip
- Klaviyo: The gold standard for e-commerce email, but starts at $45/mo for 1,001+ contacts. Brevo at $9/mo handles 80% of what startups need. Switch to Klaviyo when your email revenue justifies the premium.
- Shopify apps (most of them): The average Shopify store uses 6 paid apps at $20–$50/mo each. Start with zero. Add apps one at a time, measure revenue impact for 30 days, and remove any that don't pay for themselves.
- Hotjar/Heatmaps: Interesting but not actionable until you have 1,000+ monthly visitors. Focus on traffic first, optimization second.
- Paid social media tools: Post manually until you consistently publish 5+ times per week. Buffer Essentials ($6/channel/mo) is the first upgrade worth making.
Common Mistakes E-commerce Startups Make
- Installing 10 Shopify apps on day one. Each app adds cost ($20–$50/mo), potential conflicts, and page load time. Start with zero apps. Shopify's built-in features cover more than you think.
- Choosing Mailchimp because it's familiar. Mailchimp charges per contact. E-commerce stores build large customer lists fast. Brevo charges per email sent, which is fundamentally cheaper for stores with big lists and moderate send frequency.
- Skipping email marketing entirely. Abandoned cart emails alone recover 5–15% of lost sales. At $9/mo, Brevo Starter is the highest-ROI tool in this entire stack.
- Paying for Shopify ($105/mo) before needing it. Basic ($39/mo) handles up to 77% shipping discounts and 2 staff accounts. Upgrade to Shopify plan only when you need 5 staff accounts or better shipping rates.
Frequently Asked Questions
Can I start even cheaper?
Yes. Use Brevo Free (300 emails/day, Brevo branding), Plausible's 30-day trial, and Make Free (1,000 ops, 2 scenarios). That drops fixed costs to $39/mo (Shopify only). But you'll outgrow the free tiers quickly once orders start flowing.
Why Shopify and not WooCommerce or BigCommerce?
Shopify gives startups the fastest path to a working store with the least technical overhead. WooCommerce requires managing WordPress hosting. BigCommerce has revenue-based mandatory plan upgrades ($50K, $180K thresholds). For a startup, Shopify Basic's simplicity is worth the $39/mo.
When should I switch from Brevo to Klaviyo?
When email generates 20%+ of your revenue and you need advanced product recommendation emails, predictive analytics, and deep Shopify integration. That typically happens around $10K–$20K/mo in revenue.
