An enterprise website usually means a main domain plus regional versions, brand sites, microsites and internal hubs for employees, often run by different teams on different systems. A corporate website redesign at that size is mostly consolidation: deciding what merges, what stays local, and who can publish once the agency has gone. The 10 agencies below all name work for very large organizations on their own websites.
Five measures decide the order: how many live sites each agency names, whether it reports results for named clients, how large and complex its enterprise projects are, its range across CMS platforms, migrations and multi-site setups, and how deep its team runs.
How to choose
If you run too many sites
Consolidation work is the closest match. Isadora Agency merged a client's eight employee benefits websites into one hub, and Code and Theory designed one centralized CMS for a group of 39 local news stations.
If the site sells online
Merkle and VML lead with commerce. Merkle moved a retailer's online store to Shopify, and VML re-platformed 46 online stores across five brands for a technology products distributor.
If the site serves many countries
Valtech built a global Sitecore platform for an accounting and payroll software company that marketing teams in different countries can test and update, and Bounteous built a shared content model for a company that sells in more than 100 countries. Isadora built regional versions of a benefits hub for Asia-Pacific, Latin America, Europe, the Middle East and Africa.
If a campaign launches with the site
Critical Mass and Monks pair website work with brand campaigns and media. Monks delivered an asset manager's new identity, go-to-market plan and omnichannel marketing as one program, and Critical Mass keeps brand creative, experience design and commerce within the same team.
Several projects on this list start with too many websites
Several cases on this list are about reducing the number of sites. News Corp had benefits information on eight separate websites before Isadora merged it into one hub. Code and Theory designed one centralized CMS for TEGNA's 39 local news stations, and Premier Farnell's regional commerce platforms were pulled together when VML re-platformed 46 of its online stores.
Consolidation projects get tested after launch: the useful evidence is whether the client's own teams can publish across the merged estate, and whether the agency was asked back for regional versions or new brands.
Six of the 10 agencies belong to larger groups
Code and Theory (Stagwell), Merkle (dentsu), VML (WPP), Monks (S4Capital) and Critical Mass (Omnicom) are each part of a holding company, and Work & Co belongs to Accenture, a consultancy. A group-owned agency can bring in sister firms for media, data or commerce, which suits a program that covers all three.
Isadora is female-owned, with 11 to 50 people. Its News Corp relationship has run for more than eight years, with the same agency handling CMS and plug-in updates, site audits and each year's enrollment content.
What enterprise website design costs
Isadora's project inquiry form is the only published price among these agencies. Its website and product design budgets start with a $95K to $165K band and run through two middle bands to a top band of $401K and above. The other nine quote after a discovery phase, and several of them sell websites alongside data, media or commerce services, so a quote may bundle that work.
At enterprise size, the bill is driven by how many sites are being merged, how many languages and regions need content, which systems the CMS has to exchange data with, and whether the agency stays on to maintain the platform. It's easier to compare a quote that prices migration, integrations and post-launch support as separate lines.
