RMDB vs Microsoft Dynamics 365 Business Central: SMB Cloud ERP vs Scheduling
Business Central is Microsoft's small-to-mid business cloud ERP with a manufacturing module. RMDB is finite-capacity scheduling. Different scope, different deployment effort.
The short answer
Business Central is a solid choice for small-to-mid manufacturers wanting Microsoft-aligned cloud ERP with broad capability. RMDB adds the finite-capacity scheduling depth BC manufacturing scheduling does not match. The combination works well for BC shops with serious scheduling needs.
RMDB is the product this comparison is written about. EDGEBIC is its current generation and carries the same scheduling engine forward; see the upgrade path.
Why this comparison matters
Microsoft Dynamics 365 Business Central (the cloud successor to Dynamics NAV / Navision) targets small-to-mid businesses with general-purpose ERP plus industry modules. The Manufacturing extension adds BOM, MRP, work orders, and basic scheduling for manufacturing customers. Microsoft's ecosystem (Power BI, Power Apps, Office 365) makes BC particularly attractive for shops already standardized on Microsoft.
BC manufacturing scheduling handles work order sequencing and basic capacity loading. It is not finite-capacity APS in the technical sense — sequence-dependent setup, what-if branching, and constraint-aware automatic optimization are not part of its scope. For shops with simple sequential routings, BC scheduling is sufficient; for shops with complex setup-dependent logic, it is not.
RMDB adds finite-capacity scheduling depth and works beside Business Central through Excel, CSV or database import-export masks, the documented method for Microsoft Dynamics. For BC shops with growing scheduling complexity, RMDB is the targeted upgrade without disrupting the rest of the Microsoft-aligned ERP.

Pricing comparison
RMDB (installed base)
Now EDGEBIC
RMDB licenses stay supported; new licenses are EDGEBIC (RMDB 2.0) by User Solutions
EDGEBIC (current generation)
$25,000 or $35,000
One-time perpetual license, APS or Complete
Microsoft Dynamics 365 Business Central
$70–$100/user/month (Essentials or Premium)
Per-user subscription
RMDB is no longer sold as a new license, and existing RMDB installations remain fully supported by User Solutions; current pricing is for EDGEBIC (RMDB 2.0) by User Solutions.
Business Central is per-user subscription, $70/user/month (Essentials) or $100/user/month (Premium — required for manufacturing). A 20-user mfg shop runs $24K annually. RMDB, now EDGEBIC (RMDB 2.0) by User Solutions, at $25,000 (APS) or $35,000 (Complete) one-time with updates included, covers the scheduling depth. Combined BC + RMDB is typically cheaper than higher-end alternatives.
Where each tool wins
RMDB does this better
- BC shops where scheduling depth has become the constraint
- Operations with sequence-dependent setup complexity
- Manufacturers needing on-premise scheduling option
- Shops preferring one-time scheduling license
- Operations needing what-if scenario branching
Microsoft Dynamics 365 Business Central does this better
- Small-to-mid manufacturers wanting Microsoft-aligned ERP
- Operations leveraging Microsoft ecosystem (Power BI, Power Apps, Office 365)
- Companies preferring cloud-only deployment with Microsoft Azure
- Shops with simpler scheduling needs that BC built-in covers
- Manufacturers wanting general business ERP plus manufacturing module
Which one should you pick?
Choose RMDB if…
BC shops where scheduling has become the bottleneck. Also for small-to-mid manufacturers needing focused finite-capacity scheduling depth.
Choose Microsoft Dynamics 365 Business Central if…
Small-to-mid manufacturers $1M–$50M wanting Microsoft-aligned cloud ERP with broad business capability, where scheduling complexity is modest.
Switching from Microsoft Dynamics 365 Business Central to RMDB
A practical migration path that most manufacturers complete in days, not months.
- 1
Keep Business Central for ERP
BC continues handling financials, order management, inventory, and core ERP. Only scheduling moves to RMDB.
- 2
Map BC exports to import masks
Work orders, routings, and BOMs exported from Business Central come into RMDB through Excel, CSV or database import masks, mapped once and saved; schedules and completion data go back out the same way.
- 3
Define RMDB scheduling rules
Map work centers, shift calendars, setup time logic. BC routing data populates the base configuration.
- 4
Parallel run for 2 weeks
Compare RMDB schedule against BC output and shop floor reality.
- 5
Transition fully
Move scheduling to RMDB. BC scheduling unused; BC subscription continues for ERP value.
Frequently asked questions
Does Business Central require the Premium tier for manufacturing?+
Yes — the Manufacturing module requires BC Premium ($100/user/month vs $70 for Essentials). For a manufacturing shop, Premium is the typical license.
How well does BC manufacturing scheduling work?+
It handles work order sequencing, basic capacity loading, and material planning. It is not finite-capacity APS. For shops with sequential routings and basic capacity needs, BC scheduling is sufficient. For shops with sequence-dependent setup or alternate routing complexity, the gap is structural and RMDB is the typical add-on.
What about Microsoft Power BI integration for scheduling reporting?+
BC has native Power BI integration. RMDB, now EDGEBIC (RMDB 2.0) by User Solutions, exports schedules and dates to Excel, CSV or database tables, which Power BI can read alongside BC data. EDGEBIC also has its own reports for OEE, utilization, on-time delivery and earned value.
Is BC the same as Dynamics NAV or AX?+
BC is the cloud successor to NAV (Navision). NAV was the small-to-mid product; AX (now Finance & Operations) was the enterprise product. BC inherits NAV's capability and architecture; it is targeted at small-to-mid businesses including manufacturing.
What is the total 5-year cost for a 25-user manufacturing shop?+
BC Premium at $100/user/month × 25 users × 60 months = $150K. RMDB-engine scheduling: EDGEBIC APS (RMDB 2.0) by User Solutions at $25K one-time, updates included, no per-seat annual fee. Combined ~$175K with substantially better scheduling than BC alone.
