A new feature alone is not a reason to invest. This overview offers topics to evaluate in your store, not a ranking of the Czech market or a return forecast. Start with a problem visible in orders, support or operating costs.
This overview has eight topics to test in your own store, not a ranking of the Czech market or a return forecast. Start with one documented obstacle in orders, support or operating costs. Google's threshold for good LCP is 2.5 seconds at the 75th percentile of visits, assessed separately for mobile and desktop. For delivery, calculate the date from actual stock, dispatch cut-offs and carrier terms. I can help with a specific brief through custom e-shop development from €3,200.
1. Recommendations and search
A larger catalogue may benefit from search that understands a typo or a customer's name for a product. Complementary products can justify testing recommendations. AI is one option; manually maintained relationships may suffice for a small catalogue.
What to check for recommendations
- Data and availability check product data quality and recommended stock availability
- Metric choose first: completed orders, margin or unsuccessful searches
- Privacy assess behavioural personalisation against privacy and consent requirements
- Cost and upkeep compare the benefit with tool costs and maintenance time; a larger basket need not mean more profit
2. Social networks as a sales channel
An advertisement linking to your store is different from checkout completed within an app. Catalogue, product tagging and checkout availability can differ by country, account and platform. This article does not claim that every Meta Shops or TikTok Shop feature is available to Czech merchants.
Before integrating, verify eligible countries, order transfer, fees and returns in the platform's current terms. A real product demonstration linking to its detail page may be enough for an initial test. Measure completed purchases and cost, not just views.
3. Specific material and packaging information
Instead of a broad "eco-friendly" label, provide substantiated details: packaging composition, recycling instructions, product origin or spare-part availability. Offsetting emissions alone does not establish that delivery has no climate impact.
Second-hand or refurbished goods can broaden the range if you can describe their actual condition and sale terms. Assess logistics, inspection and returns costs; loyalty and higher margins cannot be promised in advance.
4. Payment methods based on actual use
This table is a checklist, not a Czech popularity statistic.
| Method | What to check before launch |
|---|---|
| Card | Fees, failed payment and refunds |
| Bank transfer | Matching and unpaid stock reservations |
| Digital wallet | Supported devices, gateway and a real test |
| Cash on delivery | Price and uncollected parcel costs |
| Deferred payment | Provider terms, cost and returns handling |
Deferred payment is not automatically interest-free or suitable for every range. Decide from the actual contract and test results.
5. A delivery promise you can meet
Choose delivery methods from parcel dimensions, destination and carrier capabilities. A locker may not fit a bulky product, and same-day delivery may not cover the customer's address.
A delivery promise step by step
- Price and options show them before a binding order
- Date calculate from actual stock, dispatch cut-offs and carrier terms
- Tracking provide it after dispatch where available
- Changes promise them after ordering only if operations actually support them
6. The mobile journey from product to payment
Find your mobile traffic share in your own measurement. Regardless of that share, test variant selection, forms, the keyboard, price summary and return from payment on a phone.
Google's good LCP threshold is 2.5 seconds at the 75th percentile of visits, assessed separately for mobile and desktop. One fast laboratory run does not demonstrate that result. LCP methodology.
Checkout screen count alone does not determine quality. Clear errors, preserving entered data and visible costs matter. An installable web application is an optional feature with development and support costs, not a mandatory shop foundation.
7. Content that helps selection
A guide helps when customers need to compare compatibility, sizes or usage. Do not launch a blog simply to increase article count. Start with support questions and add answers to the relevant product or category.
Actual use, dimensions or limitations can be more helpful than generic sales copy. Obtain permission for customer photographs and describe review origins truthfully.
8. Automation with a human handover
An automatic dispatch notice or order-status lookup can reduce manual work if it accesses correct information. Check AI responses about returns, prices and stock against current rules and data.
Customers should know whom they are communicating with and have an accessible route to a person. Test missing orders, integration failures and questions the system cannot answer before launch.
Legal checks for your actual operation
Check discount displays, review information, personal data and cookies against your store's features. These are not changes that all started simultaneously in 2026.
Accessibility depends on statutory scope and exemptions; see e-shop accessibility. AI obligations vary with role and use; not every AI text requires identical labelling. See the AI Act article for details and transition rules.
Choosing a priority
Select one evidenced obstacle and define cost and evaluation. Expand a feature based on results, including margin, returns and support work. None of these directions guarantees payback.
What to take away
- A new feature alone is not a reason to invest; start with an obstacle you see in orders, support or operating costs.
- The overview offers topics to evaluate, not a ranking of the Czech market or a return forecast.
- For each idea, choose the metric first and compare the benefit with tool costs and maintenance time.
- Check the availability of social platform features and payment terms in their current conditions and with your own test.
- Build the delivery promise on actual stock, dispatch and carrier capabilities.
- None of these directions guarantees payback; expand a feature based on results, including margin, returns and support work.
