Why Aviance

A slow, plugin-heavy store costs you sales every single day.

Pre-made theme stores slow down under traffic spikes and suffer from checkout drop-offs. Here is the Aviance advantage.

What matters Template or generic agency An Aviance build Engineered for ROI
Page Speed Bloated with 30+ third-party apps and slow rendering times Under 1.2s product load speed with native custom code and zero app bloat
Mobile Checkout Multi-step clunky checkout that frustrates smartphone shoppers Frictionless one-page mobile checkout with Apple Pay & Google Pay
Scalability Crashes or slows to a crawl during flash sales and marketing pushes Engineered for high concurrent traffic spikes with edge caching
Catalog Filtering Slow full-page reloads when customers filter by size, color, or price Instant AJAX/Faceted filtering without frustrating page reloads
Code & Data Ownership Restricted by proprietary limits or monthly subscription fees on basic tools You own all custom theme code, customer data, and repository access

Engineered for mobile revenue

Over 70% of e-commerce traffic is mobile. We design thumb-accessible shopping journeys that convert on smartphones.

Strict checkout testing

Every payment gateway, coupon code, tax rule, and shipping fee calculation is tested with live test transactions before launch.

Zero app dependency bloat

We build features natively (swatches, bundles, countdowns, popups) directly in clean code rather than adding paid, slow apps.

01How much does it cost to build an e-commerce website in 2026?

The cost to build an e-commerce website depends on the platform, catalog size, and custom feature requirements. A custom Shopify or WooCommerce store for small-to-medium businesses typically ranges between $800 and $1,800. Larger enterprise storefronts with custom product configurators, multi-currency checkout, and ERP inventory sync range from $2,500 to $6,000+. We provide a detailed written scope with guaranteed fixed milestone pricing.

02Should I choose Shopify or WooCommerce for my online store?

Shopify is best if you want an all-in-one hosted solution with minimal server management, built-in fraud prevention, and reliable global checkout out of the box. WooCommerce is the better choice if you want 100% control over your database, zero platform transaction fees, extensive custom content integration with WordPress, and total server autonomy. During our discovery phase, we evaluate your transaction volume, margins, and technical needs to recommend the ideal platform.

03How long does it take to build and launch an e-commerce store?

A standard custom e-commerce store build takes between 6 and 8 weeks from initial kickoff to live launch. This includes 2 weeks for UX/UI design and wireframes, 3 weeks for frontend theme coding and platform setup, 1 week for product catalog migration and payment gateway integration, and 1 week for end-to-end checkout testing and launch QA. Urgent store launches can be phased or expedited upon request.

04Which payment gateways can you integrate into my store?

We integrate all major global and regional payment gateways, including Stripe, Razorpay, PayPal, Apple Pay, Google Pay, Klarna, Afterpay, Authorize.net, and Cash on Delivery (COD) with OTP verification. All integrations comply strictly with PCI-DSS requirements and 3D Secure 2.0 (3DS2) protocols to minimize fraudulent chargebacks.

05Can you migrate my products, customers, and order history from my old store?

Yes, we handle complete data migrations without data loss or downtime. We securely migrate your product catalog (including images, variations, and tags), customer records, order history, and coupon codes from platforms like Magento, OpenCart, Wix, BigCommerce, or custom databases into Shopify or WooCommerce. We also configure 301 redirects for all legacy product URLs to preserve your existing Google SEO rankings.

06Will my store load quickly on mobile devices?

Yes. Mobile speed is our top priority because over 70% of e-commerce transactions occur on mobile devices. We build lightweight, bespoke themes that avoid bloated multi-purpose templates and unused third-party plugins. We utilize modern image compression (WebP/AVIF), defer non-critical scripts, and implement aggressive caching to guarantee sub-1.5 second product page loads and 90+ mobile Lighthouse scores.

07Can non-technical team members manage products and inventory easily?

Yes, absolutely. We configure intuitive back-end admin dashboards where non-technical staff can effortlessly add new products, adjust pricing, manage inventory levels, print shipping labels, and review sales analytics. We also provide a recorded video training session and a written handover manual tailored specifically to your store setup.

08What is headless commerce and do I need it?

Headless commerce separates the front-end presentation layer (built with modern frameworks like Next.js or React) from the back-end e-commerce database (like Shopify or Medusa.js). It delivers instant, sub-second page transitions, complete design freedom, and seamless omni-channel experiences. Headless is ideal for high-growth brands generating over $1M annually or teams with complex custom UI requirements.

09How do you protect my e-commerce store from security threats and fraud?

We implement SSL encryption, enforce secure HTTPS protocols, set up Cloudflare DDoS protection, configure rate-limiting on checkout endpoints, and implement AI fraud detection rules (such as Stripe Radar or Razorpay Thirdwatch). On WooCommerce builds, we harden server environments, disable XML-RPC, and maintain automated daily off-site cloud backups.

10Do you provide ongoing maintenance and support after launch?

Yes. E-commerce stores require continuous care to ensure payment webhooks function smoothly, software remains patched, and traffic spikes do not disrupt checkouts. Our e-commerce care plans start from $65 per month and include 24/7 uptime monitoring, plugin security updates, automated backups, and a monthly pool of developer hours for promotional banners and conversion improvements.
