This list covers Montevideo web developers with verifiable e-commerce delivery records, not agencies that added a Shopify logo to their portfolio page.

E-commerce sites handling card payments must be PCI DSS compliant-Shopify Payments and Stripe handle this by default; self-hosted payment processing requires a formal PCI Level 1 or Level 4 audit.
Buyer's Checklist
These are the questions and checks that separate e-commerce specialists from general web agencies who will list your sector on their homepage after you sign.
Published live stores with page speed scores above 80 on GTmetrix-ask for the report before signing
Checkout A/B testing experience: agencies that have run live split tests understand what moves conversion rates beyond gut instinct
Local payment method integrations: Stripe, PayPal, and any market-specific gateways active in Montevideo
SEO-ready product architecture: canonical URLs, structured data for products (Schema.org/Product), faceted navigation without crawl debt
Post-launch support with defined SLA-e-commerce sites fail during peak traffic, usually when you least want to be calling a developer
Platforms & Tech Stack
Shopify / Shopify Plus
Best for speed to market. Custom theme development on Shopify 2.0 gives full design control without leaving the hosted platform. Shopify Plus is the correct choice above £500,000 annual GMV.
WooCommerce
Best when the client already runs WordPress or needs customisation beyond Shopify's API surface: subscription logic, complex tax rules, multi-currency with local rounding.
Headless (Next.js + Shopify Storefront API)
Recommended for stores exceeding 10,000 monthly transactions or brands that require sub-1-second product pages. Higher build cost; dramatically better Core Web Vitals scores.
Magento 2 / Adobe Commerce
Enterprise choice for multi-store, multi-language, multi-currency setups. Requires a dedicated Magento-certified developer-not all Montevideo agencies have this.

Questions & Answers
Pre-brief questions that e-commerce businesses in Montevideo ask before commissioning a web project.
Shopify is the default recommendation for most Montevideo businesses launching a new store-faster to build, easier to operate, and lower ongoing maintenance. WooCommerce is the right choice when the client already runs WordPress or needs more complex customisation. Headless commerce (Next.js + Shopify API) suits stores exceeding £1M GMV where load speed and UX directly impact revenue.
A Shopify store with brand-customised theme costs £1,500–£5,000 in Montevideo. A custom WooCommerce build with product filtering and payment gateway integration runs £5,000–£18,000. Enterprise headless commerce starts at £25,000. Ongoing costs include hosting (£20–£200/month), platform fees (Shopify £29–£299/month), and maintenance retainers.
A Shopify store with a customised premium theme takes 1–3 weeks. A custom WooCommerce build is 4–8 weeks from brief to launch. A headless commerce platform with custom checkout flows and ERP integrations is 12–24 weeks. Timelines extend when product data, photography, or payment gateway approvals are delayed.
E-commerce development requires specific expertise that general web developers often lack: checkout conversion optimisation, inventory management integration, tax and shipping logic, and PageSpeed compliance affecting Google Shopping rankings. Ask any candidate agency to show you 3 live stores and their current Core Web Vitals scores in Google Search Console.
