How to Choose an E-Commerce Platform: 8 Questions That Save You Time and Money
When you start searching for an e-commerce platform, you’ll find dozens of comparison tables. They all look similar: checkboxes, star ratings, monthly prices. The problem is that most of them measure what’s easy to measure — not what’s easy to break.
Here are 8 questions you should answer before committing to anything.
1. What Will You Actually Pay Per Year?
The base price is just the entry fee. Real annual costs also include:
- Transaction fees — some platforms take 0.5–2% of revenue on top of the payment gateway fee
- Plugins — shipping carriers, ERP sync, loyalty program, B2B pricing. Each can cost €10–80/month
- Themes — premium designs are often a one-time €50–300 fee
- Developer time — if the platform requires a developer for customizations, budget €50–150/hour
Example: A €29/month plan + 3 plugins × €25/month = €979/year instead of the advertised €348.
Before choosing, calculate the real annual cost for your specific use case.
2. What’s Built-In vs. What Requires a Plugin?
This is the key distinction most comparisons ignore.
| Feature | Built-In | Plugin |
|---|---|---|
| Responsibility for functionality | Platform | Third party |
| Extra monthly fee | No | Yes |
| Risk of breaking after updates | Low | High |
| Support contact | One (platform) | Multiple |
The more critical functions depend on plugins, the greater your operational risk.
3. Does It Work for the CZ/SK Market?
Large global platforms treat this region as “just another European market.” Verify specifically:
- Payment gateways: GoPay, Comgate, Finby — not just Stripe
- Carriers: Zásilkovna, GLS, Czech Post, Slovak Post, PPL — with automatic label generation
- ERP/accounting: Kros, Pohoda — with order synchronization, not just CSV export
- Admin language: Czech/Slovak, not English-only
4. Can You Manage It Yourself?
Try this quick test before buying:
- Add a new product with 3 variants
- Set up free shipping above €50
- Create a discount on a specific product
- Change the text on the homepage
- Add a new shipping method
If you need to watch a tutorial or call support for any of these — that’s a noted weakness.
5. How Fast Does Support Respond?
When your payment gateway stops working on a Monday morning after a weekend sale, it matters whether someone gets back to you in one hour or 48 hours.
Before purchasing:
- Send a test message through support chat or email
- Track the response time and quality
- Verify whether support is available in your language
6. What Happens When a Plugin Breaks?
Plugins are built by third parties — small companies or individual developers. They can:
- Raise prices without warning
- Stop developing the product
- Break compatibility after a platform update
Ask yourself: Who is responsible when the plugin your payment gateway or shipping depends on breaks?
7. How Is the SEO?
E-shops live on organic traffic. Before choosing, verify:
- Configurable meta title and description per product and category
- URL structure (ideally
/category/product, not/p?id=123) - Load speed (Google PageSpeed score > 85)
- Canonical URLs and hreflang for multi-language stores
- Automatic sitemap.xml generation
8. What If You Scale?
Switching platforms after a year of operation is painful — data, SEO rankings, customer accounts, reviews. Before choosing, ask:
- Limits: How many products, orders, and customers does the plan support?
- Pricing at scale: How do fees change once I exceed X orders/month?
- API access: Is it available if I want a custom mobile app or integration?
- Data portability: Can I export my full product and customer database?
Key insight: The right platform isn’t the one with the longest feature list — it’s the one you can manage without external help and that won’t surprise you with hidden costs six months in.
