ANSWERS TO YOUR E-COMMERCE QUESTIONS
What is the real impact of load speed on e-commerce conversion rates?
In online retail, every single second of delay costs on average 10% in lost revenue, and 100ms of latency reduces conversions by 1% to 7%. An Astro Headless storefront loading in under one second removes checkout friction, cuts cart abandonment rates in half, and maximizes average order value (AOV).
Should I choose Shopify Headless or WooCommerce Headless?
It depends on your commercial requirements: Shopify Headless is ideal for international scaling with managed checkout infrastructure. WooCommerce / Stripe Headless is optimal to preserve 100% of your margins with 0% platform transaction fees and total database control. Stacky engineers both architectures seamlessly.
Can I keep my current back-office tools (Shopify, WooCommerce, ERP)?
Yes, 100%. We do not disrupt your logistics, stock management or order fulfillment workflows. We only decouple the public front-end to make it instantaneous, syncing real-time inventory and orders via secure APIs and webhooks.
How are customer payments and financial data secured?
Security is uncompromising. No sensitive financial information touches your servers: transactions are end-to-end encrypted and handled directly by PCI-DSS Level 1 certified processors (Stripe, Shopify Checkout, Mollie, Apple Pay, Google Pay).
Can we integrate tracking pixels (GA4, Meta, Klaviyo) without slowing down the site?
Yes. Powered by Astro Islands Architecture, marketing scripts and third-party tracking pixels run asynchronously in dedicated web workers without blocking UI rendering or dropping your 95+/100 Google Lighthouse score.
How much does a Headless E-Commerce store cost at Stacky?
Packages start at €2,490 ex. VAT for Starter (up to 25 products, Stripe/Shopify checkout, 95+/100 score), €4,890 ex. VAT for Pro Scaling (expanded catalog, instant predictive search, stock sync), and €7,900 ex. VAT for Enterprise solutions. 1 year of global Edge CDN hosting is included.
