About Datadial

Software that fits a business, rather than the other way round, is the line this agency has taken since 1998. It builds bespoke software and online shops from London and the Cotswolds, and its developers are based in the United Kingdom.

How a bespoke software project runs

The company lays out a three-step process. Discovery and planning begins with the client's business objectives and requirements, and ends in a fixed-price proposal with realistic timelines. The build stage uses sprints with regular check-ins, and clients are included in a Teams chat and speak straight to the people writing the code, with no account managers in between. After launch, the company delivers tested, documented software with training for the client's team and provides managed hosting, maintenance and support. It says this approach avoids budget overruns from unclear specifications, delays from poor project management and systems that cannot scale.

E-commerce on several platforms

Shops are a long-standing specialty. Datadial develops bespoke .NET e-commerce sites and works with Magento 2, WooCommerce and Shopify. Its portfolio runs across sectors including automotive, fashion, food and wine, health and beauty, home and garden, property, publishing, textiles and curtains, travel, weddings and events, and education.

Custom systems and integrations

Beyond shops, the firm lists progressive web apps and specialist software such as science lab management, an online call centre system and a curtain ordering system. It integrates third-party systems, including Opayo and PayPal payments, Orderwise, Dez Rez and the Domus property management package, and it offers corporate web hosting, branding and graphic design.

Marketing that sits alongside the build

The agency also runs online marketing: search engine optimisation, content marketing, Core Web Vitals work, local search, conversion rate optimisation, digital PR, link building and recovery from Google penalties, plus social media and reputation management. Paid campaigns cover Google and Bing ads, Google Shopping, Amazon, TikTok, Pinterest, Facebook and Instagram, display remarketing and email marketing.
