Efficion Consulting cover

About Efficion Consulting

Based in St. Louis, Missouri, and founded in 2003, Efficion Consulting is a web application developer. It builds and links web applications for organizations that want their websites to do more for their business. Its builds draw on third party products and newer development tools, with the platform for each project chosen to suit it.

Website design and development on open platforms

The firm designs and develops websites on WordPress and DotNetNuke, a content management system built on Microsoft technology. It says it can customize sites with its own skins and modules, so that a client can have a design of their own rather than being limited to a standard theme. The company says its strength is the more technical side of web development, and that it builds sites that are fast, clean and responsive without relying on large numbers of plug-ins that slow a site down.

Online stores on ASP.NET and AbleCommerce

For retailers, Efficion builds e-commerce sites and online stores on ASP.NET and the AbleCommerce platform. The company describes its store work as part of the same development practice as its websites, so that a client's catalog, checkout and wider site are built to work together.

Connecting software and business systems

A major part of the work is integration. Efficion selects, implements and links business software of the kinds used for customer relationships, resource planning, order handling and help desk work. It also connects websites with older legacy systems and with third party software, so that information moves between them without manual re-keying.

Automated order and payment flows

The firm describes a project for a wholesale business whose sales volume had grown quickly. Efficion modernized the company's custom order management system and built automated integrations with partners' systems, using APIs, electronic data interchange and SQL. The aim was to pass order and payment information between systems automatically, removing manual steps and simplifying accounting and reconciliation.

Project management and issue tracking tools

Efficion also builds project management and issue tracking systems, which let teams record work, follow problems and see progress in one place. These tools are offered alongside the websites and integrations, for clients who want to manage their own development and support work.

Search visibility for new sites

The firm offers search engine optimization, with the aim of helping new sites rank in search results. This work is delivered with the site build, so a client's new pages are set up for search from the outset rather than adjusted afterwards.

Range of clients

The firm's examples include a national litigation firm, for which it maintains the main website, hosting, landing pages, subsidiary sites and an intranet, a local moving company whose new site was built with search work, an executive search firm whose WordPress site was built with a design agency, and a company that runs a site about outdoor destinations near St. Louis. These examples show work from small businesses to large organizations.

Technologies used

Across its projects the firm works with WordPress, DotNetNuke, ASP.NET and responsive front-end design.
