Sydney web design and software firm offering ERP systems, custom apps and SEO for small businesses

Web and mobile app developer building business systems, dealer portals and site support for UK companies

For more than fifteen years, the web and mobile developer Interlockdigital Ltd has produced bespoke sites, smartphone apps and browser-based business tools. It also takes over the support of existing sites and systems, fixing faults, tightening security and adding functions to older investments.
For manufacturers and wholesalers, the firm builds online tools for dealers and distributors. A dealer can place orders online at the terms agreed for that account, and the back office stays in step with stock, fulfilment and accounts. The company says the aim is to lower the cost of serving a dealer network, to increase sales through dealers and to free the sales team to open new accounts.
Smartphone apps are built for Android and iOS, linked to a client's web presence and to its back-office systems. The firm uses React Native and Cordova to produce apps for Android, iPhone and iPad, and its customers include organisations that want a secure customer service app or a members' app for a community of users.
The firm builds and maintains large content-managed websites with several languages and sites, with search optimisation and brand control built into the system. Clients who want a single team to run their web estate can use this service. Where a client already runs an ASP.NET, WordPress, Drupal or Expression Engine site, the company will take over its support and extend it.
Connections between separate business systems are made with XML, databases, CSV files and web services, so that information held in one package reaches the others without manual re-keying. The firm also supports ASP.NET and ColdFusion systems that are still in use, and it treats the repair and extension of those systems as a routine part of its work.
The firm offers an online sales integration for businesses that use the Opera accounting package. The company says it can help Opera users add an online shop to their service and can help them move to a newer version of the software. Its products and technologies include Nitor, the content management system it has integrated, and a Flickr component it developed for that system.
The company says its clients awarded it Recommended Agency Register status, a list the company describes as agencies that consistently exceed their customers' expectations. Recent projects named on its site include an online ordering system for a made-to-order curtain and blind maker, a customer service app for a treatment group, a mobile app for a cycle-touring community and a training platform for aircrew.
Interlockdigital Ltd is a web and mobile development company that was formerly known as Gauge Web Services. It builds custom websites, smartphone apps and web-based business systems, and takes over support of existing sites.
