Why E-commerce & Online Retail Companies Choose TAIT
Off-the-shelf store builders are fast to launch but hard to scale once you need custom pricing rules, B2B accounts, multiple warehouses or a marketplace model. TAIT builds e-commerce platforms around your catalog and operations: headless storefronts on Next.js, a Node.js commerce backend or a headless platform such as Shopify or commercetools, and integrations with the payment, tax, ERP and shipping providers you already use in the US or Europe.
Headless Storefronts
Next.js front ends decoupled from the commerce engine, so design, speed and content can evolve without replatforming.
B2B & Wholesale Logic
Customer-specific price lists, quotes, minimum order quantities, credit terms and reorder flows for trade buyers.
Payments & Tax for US and EU
Stripe, Adyen or PayPal checkouts with SCA-ready flows for Europe and sales-tax/VAT calculation through services like Avalara or Stripe Tax.
Core Web Vitals First
Image optimization, edge caching and server rendering so product and category pages stay fast on mobile.
Custom Modules & Features
Every component is designed around the way your business actually operates.
Product Catalog & Search
Variants, bundles, faceted filters and search tuned to how your customers actually shop.
Custom Checkout
One-page checkout, saved addresses, discounts, gift cards and multi-currency pricing.
ERP & Inventory Sync
Two-way integration with NetSuite, SAP, Odoo or your in-house system for stock, orders and invoices.
Shipping & Fulfillment
Rates and labels through carriers or 3PLs, split shipments and tracking notifications.
Marketplace Engine
Vendor onboarding, commissions, payouts and per-vendor catalogs for multi-seller models.
Admin & Analytics
Back office for orders, returns and promotions, with event tracking wired to GA4 or your data warehouse.
How we build your platform.

We build in short sprints with React, Next.js and Node.js, with demos you can review every step of the way.
Integrations & Cloud
We connect your third-party tools and data, and deploy on AWS or Vercel with monitoring from day one.
Support & Growth
After launch we maintain, monitor and improve the platform, including performance and technical SEO.
E-commerce & Online Retail Development FAQ
Do you work with Shopify, or only fully custom builds?
Both. We build custom storefronts on top of Shopify, commercetools or other headless platforms, and fully custom Node.js backends when the business model needs it. We recommend the option after reviewing your catalog, volume and integrations.
Can you migrate our existing store without losing SEO?
Yes. We map every old URL to its new equivalent with 301 redirects, preserve product data and structured data, and check indexing after launch.
How do you handle time zones with a US or European team?
Buenos Aires is 1 to 2 hours from the US East Coast and 4 to 5 hours from Central Europe, so we schedule daily overlap for calls and keep async updates in your project tools.
How is pricing structured?
After a short discovery call we send a written scope with a fixed estimate per phase, or a monthly retainer for ongoing development and maintenance.
