E-commerce quotes are all over the map because "online store" describes everything from 10 products sold by one person to 10,000 SKUs with warehouse integrations. Here is what each level actually costs and what you get.
Level 1: Configured platform store ($1,500 to $5,000)
Shopify, WooCommerce, or similar, set up properly: a premium theme customized to your brand, your products loaded, payments and shipping configured, taxes set, tested end to end with a real order.
This is the right choice for most businesses selling under a few hundred products. You are not paying for software, you are paying for someone to configure a machine that would take you 60 frustrating hours to configure yourself, and to configure it right.
Level 2: Customized store ($5,000 to $15,000)
Custom design instead of a themed one, plus real integrations: your inventory system, your POS, your fulfillment provider, subscription products, wholesale pricing, or multi-currency.
Best when the store IS a significant part of your revenue and the standard templates genuinely limit how you sell. The price is mostly integration work; connecting your systems is slower and riskier than setting up a standalone store.
Level 3: Custom platform ($20,000+)
Your own code, your own checkout, your own everything. Justified when your selling model is unusual (marketplaces, rentals, custom-configured products, B2B contract pricing) and no platform can express it.
Justified rarely. I have talked more owners out of this tier than into it, because "I want to own it" usually costs $30,000 to avoid $3,600 a year in platform fees, while taking on all security, compliance, and maintenance yourself.
Where the money actually goes
| Item | Typical share |
|---|---|
| Product page and checkout work | 30 to 40% |
| Design and mobile polish | 20 to 25% |
| Integrations (shipping, tax, inventory) | 15 to 25% |
| Product data entry and cleanup | 10 to 20% |
| Testing with real orders | 10 to 15% |
Note what is missing: nobody expects it, but product data cleanup is often the biggest delay. 400 products with inconsistent names, missing sizes, and iPhone-quality photos will stall any build.
The ongoing fees, honestly listed
- Payment processing: about 2.9% + $0.30 per transaction (cheaper rates exist at volume)
- Platform: $29 to $299/month for Shopify tiers, or hosting costs if self-hosted
- Apps and plugins: $20 to $200/month once you add reviews, upsells, and email tools
- Maintenance: $80 to $300/month (updates, payment health, product update help)
These recurring numbers are why the "free website" offers exist. The platform needs you subscribed forever. That trade can still be worth it, but do the 3-year math, not the monthly math.
Where I see owners overspend
Custom design before product-market fit. Your store's design matters less than your photos, your product descriptions, and your shipping prices. Get selling with a clean configured store, then invest revenue in customization that data justifies.
Where underspending costs more
Checkout and mobile. A slow or awkward mobile checkout quietly taxes every single sale. If you spend extra anywhere in level 1, spend it there. One recovered sale per day pays for the difference within a year for most stores.
Tell me what you sell, how many products, and where you sell now. I will tell you which level fits and what it should cost, including the parts other quotes leave out.
