"We Use Sage." A Guide to What Your Customer Really Means.

In our last post, we explained why Sage is a fragmented federation of acquired products. Now, it’s time to map that federation.

When a customer says, "We use Sage," they could mean a 20-year-old desktop program or a brand-new, multi-tenant cloud platform. Your integration strategy depends entirely on knowing the difference.

This post is the decoder ring. We will map out Sage's two distinct portfolios—the established desktop world and the high-growth cloud world—so you can pinpoint exactly what your customer is using.

The Legacy Champions (The Desktop World)

This portfolio is the foundation of Sage's massive market share. These products are powerful, deeply entrenched, and regionally specific.

• In North America (US & Canada): The market is dominated by Sage 50 US (formerly Peachtree), Sage 50 Canada (formerly Simply Accounting), and Sage 100 (formerly MAS 90/200).
• In the UK & Ireland: The key product is Sage 50 UK & Ireland (formerly Sage Line 50).
• In Mainland Europe: The fragmentation is even deeper. Key markets have their own "local champion" products, such as:
  • France: Sage 50 & Sage 100 (both from the acquired Ciel line).
  • Germany: Sage 50 & Sage 100 (distinct German products).
  • Spain: Sage 50 (from Contaplus) & Sage 200 (from Murano).

The integration challenge for this portfolio is significant. These are distinct codebases that often lack modern, server-side APIs.

The Modern Growth Engine (Mapping the Cloud Portfolio)

This is where Sage's strategic focus, investment, and high-growth lie. For SaaS companies, this is the future-proofed opportunity. But "cloud" is not one platform. The cloud portfolio has its own critical fragmentation.

North American-Focused Cloud

• Accounting (Mid-Market): Sage Intacct. This is the flagship API-first platform, which is now expanding globally.
• HR (Mid-Market): Criterion. The new (October 2025) acquisition to bolster US HCM and payroll.

European-Focused Cloud

• Accounting (Pan-European SMB): Sage Active. This is the new, strategic cloud-native platform for France, Germany, and Spain.
• Accounting (UK Mid-Market): Sage 200 UK. The modern, cloud-enabled solution for the UK, notable for its well-supported REST API .
• The Legacy Exception: Sage 100 Germany. Unlike its API-hostile namesakes in the US and France, the German Sage 100 is an exception, offering a modern REST API.

The Global Cloud Portfolio (Products for All Markets)

• Accounting (Small-Biz): Sage Business Cloud Accounting (formerly Sage One). The global competitor to Xero, primarily in the Anglosphere.
• HR (Global SMB): Sage HR (formerly CakeHR).
• HR (Global Mid-Market): Sage People (formerly Fairsail). A powerful HCM built on the Salesforce platform.
• ERP (Global Mid-Market): Sage 300 (formerly Accpac).
• ERP (Global Enterprise): Sage X3. A powerful, customizable ERP for manufacturing and distribution.
• CRM (Global): Sage Sales Management (formerly ForceManager).

Your Integration Strategy Is Not for "Sage"

The Sage ecosystem is really two complex ecosystems. The legacy desktop world is fragmented by region . The modern cloud world—where Sage is focusing its future—is fragmented by region, market segment, and technology.

The cloud portfolio alone is a mix of a dozen distinct platforms. Knowing this map is the first step. The next is understanding the technical implications. In our final post, we'll dive into the API playbook and show you why integrating with Sage Intacct is a completely different project than integrating with Sage Active or Sage 100 France.
