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 app 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 South Yarra
SEO-ready product architecture: canonical URLs, structured data for products (Schema.org/Product), faceted navigation without crawl debt
Post-launch support with a 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 becomes the correct choice at high annual GMV, from around £500,000 in the UK and the local equivalent elsewhere.
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 South Yarra agencies have this.

Questions & Answers
Pre-brief questions that e-commerce businesses in South Yarra ask before commissioning an app project.
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 mobile app developers often lack: checkout conversion optimisation, inventory management integration, tax and shipping logic, and App Store ratings 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.
A properly scoped mobile app development contract for a South Yarra business should include: a fixed-price quote (not hourly with uncapped scope), a detailed scope of work document, a timeline with specific milestones and delivery dates, ownership of all source code and assets on completion, a warranty period of at least 30 days post-launch for bug fixing, and clear terms for revision rounds. Avoid any contract that includes a retainer obligation as a condition of handover, this is a red flag in the South Yarra mobile app development market.
A standard business app for a South Yarra company takes 2–4 weeks from brief to launch (assuming content is provided on time). A custom web application with integrations typically takes 6–12 weeks. E-commerce sites with product catalogue setup take 3–8 weeks. The most common cause of delays in South Yarra web projects is late content delivery from the client, agree a content deadline before the project starts and the timeline holds reliably.
For most South Yarra businesses, a remote mobile app development agency delivers equivalent or better results than a local studio, at 20–40% lower cost. The key factors are: quality of portfolio (verifiable through live URLs, not PDF screenshots), communication responsiveness (same-day replies are the baseline for professional agencies), and clear ownership transfer on handover. Physical location has not been a meaningful differentiator for mobile app development quality since 2018. Tecklogist serves clients across Australia and 40+ countries entirely remotely.
The three most reliable verification methods for South Yarra businesses evaluating mobile app developers are: 1) Live portfolio links, the agency should provide direct URLs to live sites they built (not PDF mockups), which you can test for speed, mobile quality, and design; 2) Client references, ask for contact details for two recent clients in a similar sector; 3) Technical audit, ask the developer to explain how they would handle a specific technical challenge for your project. A developer who cannot answer this clearly has not built what they claim. Tecklogist provides live portfolio URLs, verified client references, and a free technical scoping call for every South Yarra project enquiry.
