Sage 100 to Dynamics 365 Data Migration
Moving from Sage 100 to Business Central? Settle automates the mapping between Sage's module-based tables and D365's data entity framework — restructuring charts of accounts, customer records, and inventory for the Microsoft platform.

Enterprise migrations routinely run months behind schedule. Yours doesn't have to.
This guide is for VPs of IT, data architects, and migration leads at companies moving data from Sage 100 to Microsoft Dynamics 365 — whether you're scoping, planning, or mid-program.
Sage 100 stores data in module-specific tables (AR_Customer, AP_Vendor, CI_Item, GL_Account) on Pervasive or SQL Server, while Dynamics 365 Business Central uses AL-based entities with posting groups, number series, and dimensional accounting. Settle translates Sage's on-premise ERP data to Business Central's cloud model automatically.

How Settle automates your Sage 100 to Microsoft Dynamics 365 migration
Settle analyzes Sage 100's chart of accounts and proposes the Business Central dimensional decomposition — splitting embedded segments into G/L accounts and dimension values based on naming patterns.
Posting group assignments are generated automatically — Settle analyzes Sage's transaction patterns to recommend Customer, Vendor, Inventory, and General posting groups with correct GL account linkage.
Multiple extraction formats supported — direct SQL Server access, Pervasive ODBC, or CSV exports. Settle profiles whichever format you can provide from Sage 100.
Settle validates trial balance reconciliation after migration — ensuring Sage 100 and Business Central balances match as of cutover date.

Common challenges migrating from Sage 100 to Microsoft Dynamics 365
Chart of accounts to Business Central dimensions
Sage 100 uses a flat or minimally segmented COA. Business Central uses G/L accounts with global dimensions, shortcut dimensions, and dimension values. The restructuring requires analyzing Sage's account naming patterns to identify embedded segments that should become dimensions.
Explore related migrations →Posting group configuration
Business Central uses posting groups (General, Customer, Vendor, Inventory) to control GL account assignment on transactions. Sage 100 assigns GL accounts directly on transactions. Setting up posting groups and mapping historical data to the correct posting logic requires careful analysis of Sage's transaction patterns.
Explore related migrations →Number series and document numbering
Sage 100 uses sequential numbering per transaction type. Business Central uses configurable number series with prefixes and gaps. Migrated documents must preserve original numbers while Business Central's series starts from the correct next value.
Explore related migrations →Inventory costing and tracking
Sage 100's inventory costing methods (FIFO, LIFO, Average, Standard) must map to Business Central's costing method field. Lot and serial tracking configurations differ between platforms. The valuation method must align before inventory data can load correctly.

10 data objects typically migrated
| Source Object | → | Target Object |
|---|---|---|
| AR_Customer | → | Customer |
| AP_Vendor | → | Vendor |
| GL_Account | → | G/L Account + Dimensions |
| GL_DetailPosting | → | General Journal |
| CI_Item | → | Item |
| SO_SalesOrderHeader | → | Sales Order |
| PO_PurchaseOrderHeader | → | Purchase Order |
| AR_OpenInvoice | → | Sales Invoice |
| AP_OpenInvoice | → | Purchase Invoice |
| PR_Employee | → | Employee |
Typical enterprise migrations include 500K–10M+ records across these objects. Settle handles profiling and mapping at enterprise scale.
The cost of manual Sage 100 to Microsoft Dynamics 365 migration
Sage 100 to Dynamics 365 Business Central is a natural upgrade path for Microsoft-aligned companies. Sage 100 runs on Windows with Office integration, so companies already familiar with the Microsoft ecosystem often prefer Business Central over NetSuite. This migration is common among companies at the $10M–100M revenue range that want cloud ERP, Power BI reporting, Teams integration, and Power Automate workflows — all native to the Microsoft stack.
The migration translates Sage 100's module-based tables to Business Central's entity model. Sage's flat chart of accounts needs Business Central's dimensional restructuring with G/L accounts, global dimensions, and shortcut dimensions. Customer and vendor records need posting group assignments. Inventory items need Business Central's item tracking and costing configuration. The platforms use different transaction processing models.
Companies typically manage this during a Business Central implementation using RapidStart Services or CSV imports. The posting group configuration and dimensional accounting setup are the most manual parts.
Consulting-led delivery for migrations in this class typically runs $250K–$600K. Settle prices it fixed and scoped — read the full cost breakdown.
