Who this stack is for
You run an e-commerce store as a side business or a growing full-time hustle doing $1k–$30k/mo in revenue. You ship physical or digital products. You’re on Shopify or you plan to be. You are one person, or two if you count your friend who helps pack orders.
If you’re a dropshipping arbitrage operator, this stack still applies but you’ll need more automation glue (Oberlo → AutoDS → etc.). That’s a different playbook.
If you’re an established DTC brand at $50k+/mo, the shape of this stack is right, but every tool should level up — Klaviyo over Mailchimp, Gorgias over Inbox, proper 3PL integration, etc.
The essential stack (Day 1)
Store platform: Shopify Basic
Shopify at $39/mo (Basic) handles the store, hosting, SSL, checkout, payments, and 98% of what a side hustle needs. If you’re philosophically anti-SaaS or already running a WordPress site, WooCommerce is fine but you’ll spend time on hosting + plugins that Shopify hands you.
Email marketing: Mailchimp (or Klaviyo if $10k+/mo)
Mailchimp is the right pick if you’re under $10k/mo — Shopify integrates it out of the box, the free tier covers 500 contacts, and the effort-to-result ratio is good. At $10k+/mo, switch to Klaviyo — the revenue attribution and segmentation are categorically better, and you’ll earn back the higher price from the first flow you build.
Bookkeeping: QuickBooks Online
QuickBooks Online with Shopify integration gives you sales tax by state automatically, COGS tracking, and the export your accountant wants at tax time. Simple Start ($35/mo) is enough until you have employees or inventory complexity.
Password manager: 1Password
1Password lives up there with your store and bookkeeping — it’s infrastructure. Shopify admin password, payment gateway admin, email platform, supplier portals — all need to live somewhere that isn’t your browser’s memory.
Add these as you grow
- Klaviyo at $10k+/mo — better revenue attribution than Mailchimp; will pay for itself.
- ShipStation at $5k+/mo in orders — unified shipping across USPS + UPS + FedEx rates.
- Gorgias when support email ≥ 10/day — Shopify-native helpdesk beats gmail tabs.
- Shopify Audiences if running Meta/Google ads at $2k+/mo.
Skip these (but everyone recommends them)
- Dedicated CRM (HubSpot Starter, Pipedrive) — Shopify’s customer data + Klaviyo’s flows are your CRM. Don’t add a third system.
- Dedicated product review platform (Yotpo, Loox) — Shopify’s free Product Reviews app handles this until you’re at real scale.
- Advanced inventory management (Cin7, DEAR) — Shopify’s native inventory is enough under ~1,000 SKUs.
Shopify app sprawl — the warning
Shopify App Store is a trap. Every app is $10–30/mo, adds a bit of “value,” and suddenly you’re at $300/mo in apps. Audit quarterly:
- List every Shopify app charge. Billing → Apps.
- For each: last 30-day usage? If you can’t answer “yes, I used it X times last month” — uninstall.
- Target: total app spend ≤ $50/mo at $5k/mo revenue. Scale with revenue, not ambition.
Total monthly cost
At day-1 prices:
- Shopify Basic: $39
- Mailchimp (under 500 contacts): Free
- QuickBooks Online Simple Start: $35/mo
- 1Password Individual: $3/mo
- Total: $77/mo
Scale up: Klaviyo at $30-100/mo, ShipStation at $10-50/mo, apps at $30-70/mo. A $15k/mo store can easily be paying $250/mo in SaaS and still be healthy margin-wise.
FAQ
Shopify or WooCommerce for a side hustle?
Shopify unless you have strong reasons to be on WordPress (content strategy, existing site, philosophical preference for self-hosting). The hours you save on infrastructure are worth the monthly fee.
Do I need Klaviyo from day one?
No. Mailchimp is cheaper and easier to get running. Switch when the math justifies it (usually around $10k/mo or when basic email ROAS isn’t enough).
Should I run ads before email marketing is dialed in?
No. Emails to existing customers are 10x the ROAS of cold ads. Fix the email engine first. Then add ads.
