Is Microsoft Dynamics SL the same as Solomon?

Yes. Dynamics SL was originally sold as Solomon Software before Microsoft acquired it and rebranded the product. Many longtime users still call it Solomon, and both names refer to the same ERP system.

What does Microsoft Dynamics SL do?

Dynamics SL combines project management and financial management in one system, so project-driven companies can handle job costing, billing, time and expense tracking, distribution, and core accounting from a single platform. Its strength lies in keeping project data and financial data connected.

Is Microsoft Dynamics SL still available to new customers?

No. Microsoft closed Dynamics SL 2018 to new customers on September 30, 2023, so organizations that do not already own it can no longer purchase the product. Existing customers may still be able to add perpetual users to their current Dynamics SL system until January 15, 2030, subject to their licensing and service-plan arrangements. However, Microsoft’s extended product support ends earlier, on July 11, 2028.

Will Dynamics SL stop working after July 11, 2028?

Your software will not switch off on that date, but Microsoft's extended support ends, which means no further security updates or fixes will be available. Continuing to run SL past that point exposes your business to growing security, compliance, and integration risks, which is why Microsoft recommends planning a migration ahead of the deadline.

What is replacing Microsoft Dynamics SL?

Microsoft points SL customers to Dynamics 365 Business Central, its modern cloud ERP for small and midsize businesses. Business Central is positioned as the successor to mid-market legacy Dynamics products and delivers similar functionality with cloud flexibility and automatic updates.

Can Dynamics SL data be migrated to Business Central?

Yes. Microsoft provides cloud migration tools that can move supported financial, customer, vendor, inventory, open-transaction, and selected historical data from Dynamics SL to Business Central. Project records, custom tables, integrations, and specialized historical data may require additional assessment, mapping, or migration work. A structured SL to Business Central migration plan helps protect data integrity, identify unsupported records, and confirm that critical information is accounted for before go-live.
