What kind of ROI can I expect from an eCommerce agency?
A well-developed and designed eCommerce store delivers an average ROI of 10%-30%.
However, the return on investment depends on your goals, platform type, target markets, business benchmarks, success metrics, and ongoing marketing strategies.
For instance, a Shopify fashion brand has an average conversion rate (CVR) of 1.6%-1.9%. But home electronics see higher returns at a CVR of 3%-3.6%, while the beauty and personal care sector experiences an average CVR of 6.5%-6.8%.
Here are the general global benchmarks of eCommerce store development and optimization:
Conversion rate: 1-2%
Average order value: $50-$100
Cost per click: Below $1
Cost per acquisition: Below $25
How long does it take to build an eCommerce website?
The time required to build an eCommerce website depends on scope, platform, content volume, and the number of integrations involved. Based on averaged industry timelines from established eCommerce projects, typical ranges are as follows:
Simple template-based stores usually take 4 to 8 weeks, covering discovery, light design customization, product setup, QA testing, and launch.
Mid-sized custom stores generally take 8 to 16 weeks, allowing time for custom UI/UX design, feature development, integrations, testing, and post-launch fixes.
Complex stores with integrations often require 4 to 6 months, as custom functionality, third-party systems, performance optimization, and extended QA increase build time.
Full migration projects typically take 8 to 20 weeks, depending on catalog size, data cleanup, SEO preservation, and parallel testing.
What platform should I choose for my eCommerce site?
The right eCommerce platform depends on your business size, customization needs, internal resources, and long-term growth plans.
Shopify is best for small to mid-sized businesses that want fast setup, reliable hosting, and an all-in-one solution with minimal technical overhead.
WooCommerce is best for content driven businesses that already use WordPress and need flexible customization with lower upfront costs.
Magento, also known as Adobe Commerce, is best for large or complex stores that require deep customization, advanced catalog management, and enterprise integrations.
BigCommerce is best for growing brands that want strong native features, multi-channel selling, and scalability without heavy custom development.
Headless commerce is best for brands that need maximum flexibility across web, mobile, and emerging channels while decoupling the frontend from the backend.
