RMDB vs Epicor: Honest Comparison for Manufacturers Who Just Need Better Scheduling
Epicor Kinetic is a complete enterprise ERP — powerful, expensive, and built for large mid-market firms. RMDB is finite-capacity production scheduling that installs in 5 days and starts at $5,000. Here is how they really compare.
The short answer
Epicor Kinetic is the right call for manufacturers who need a fully integrated ERP spanning financials, HR, supply chain, and production — and have the budget ($50k–$200k+/year) and runway (12–18 months) to match. RMDB is the right call when your real problem is the production schedule: you need finite-capacity planning, drag-and-drop Gantt, setup-time modeling, and bottleneck visibility without replacing your existing ERP or committing to an 18-month implementation.
Why this comparison matters
Epicor Kinetic (formerly Epicor ERP) is one of the most established names in mid-market manufacturing software. It covers the full breadth of enterprise operations — general ledger, accounts payable, CRM, supply chain, production orders, quality, HR, and more. For a $50M+ manufacturer ready to consolidate every business system into one vendor, Epicor Kinetic is a serious contender.
The friction appears when manufacturers realize how much of the Epicor investment exists outside the scheduling problem they actually need to solve. Epicor's Advanced Planning and Scheduling (APS) module is a powerful tool — but it sits on top of a full ERP implementation that takes 12 to 18 months and costs $50,000 to $200,000 or more annually. For job shops, machine shops, and make-to-order manufacturers with 10 to 300 employees, that is not a scheduling upgrade. That is a complete business transformation with a scheduling component buried inside it.
RMDB by User Solutions takes the opposite approach. It is a pure finite-capacity scheduling and production planning system — nothing more, nothing less. It integrates with Epicor (and Epicor JobBOSS, QuickBooks, Sage, Dynamics, SAP, and any other ERP you already have), installs in 5 days, and costs a fraction of the Epicor APS bundle. This page is the head-to-head comparison between the two, built for manufacturers trying to decide whether to buy all of Epicor or just replace the scheduling piece.

The pricing gap between RMDB and Epicor is not incremental — it is an order of magnitude. A full Epicor Kinetic deployment for a mid-market manufacturer typically costs $50,000 to $200,000 or more per year once you account for user licenses, modules, implementation services, and annual maintenance. RMDB starts at a one-time $5,000 and most shops land between $10,000 and $30,000 all-in. If your primary need is finite-capacity scheduling rather than a complete ERP replacement, the math makes RMDB difficult to argue against.
Where each tool wins
RMDB does this better
- Pure finite-capacity scheduling depth — the thing Epicor APS charges a premium for and requires a full ERP to access.
- Implementation speed — 5 days vs 12–18 months. You are running a real schedule before the end of week one.
- Total cost — $5,000 one-time vs $50,000–$200,000+/year recurring.
- Works alongside your existing ERP — no platform migration required.
- Drag-and-drop Gantt with constraint-aware reschedules available to all users out of the box.
- Setup-time sequencing and bottleneck analytics without additional module fees.
- Right-sized for job shops and make-to-order manufacturers with 10–500 employees.
Epicor does this better
- Complete ERP suite — financials, HR, CRM, supply chain, and production all under one roof.
- Purpose-built for large mid-market manufacturers ($50M+ revenue, 100+ employees) who need enterprise-wide software consolidation.
- Stronger supply chain and procurement workflows for companies with complex multi-site sourcing.
- Deep industry-specific compliance modules (defense, automotive, aerospace) built into the platform.
- Single vendor for everything — one support contract, one implementation partner, one upgrade cycle.
Which one should you pick?
Choose RMDB if…
Your real bottleneck is the production schedule — not missing financials or HR software. You have multi-step routings, setup times, finite resources, and daily reschedules. You already have (or want to keep) a separate ERP or accounting package, and you need finite-capacity scheduling to work alongside it rather than replace everything you have. Budget matters and 5-day implementation beats 18-month transformation.
Choose Epicor if…
You are a mid-to-large manufacturer ($20M–$500M+ revenue) that needs a single vendor to consolidate financials, HR, CRM, supply chain, and production. You have a multi-year IT roadmap, an executive sponsor, a dedicated implementation budget, and the organizational bandwidth for an 18-month enterprise software project. The scheduling module is one item on a longer list of business systems you need to replace.
Switching from Epicor to RMDB
A practical migration path that most manufacturers complete in days, not months.
- 1
Identify what Epicor is solving vs what scheduling needs
Many manufacturers considering Epicor only need better scheduling — not a new ERP. We help you map your current pain points to specific capabilities so you buy only what solves the actual problem. If you have an existing ERP that handles financials well, RMDB adds scheduling depth without displacing it.
- 2
Export production data from your current system
Whether you are coming from Epicor JobBOSS, an older Epicor version, or any other ERP, we export the entities that matter for scheduling: work centers, routings, BOMs, open orders, and shift calendars. Standard CSV or direct database connection — whatever your system supports.
- 3
Build finite-capacity routings in RMDB
If your current system uses infinite-capacity or simplified routings, we rebuild them in RMDB with proper setup times, resource constraints, and sequencing rules. This is where finite-capacity scheduling starts paying off — the schedule finally reflects how your floor actually runs.
- 4
Wire RMDB into your existing ERP or accounting system
RMDB integrates with Epicor, Epicor JobBOSS, QuickBooks, Sage, Microsoft Dynamics, SAP, and any other ERP via API or file-based exchange. Production data flows both directions without re-keying — schedulers work in RMDB while accounting and purchasing stay in whatever system they already use.
- 5
Train your schedulers and go live in 5 days
Standard 5-Day Implementation Framework — RMDB is configured, integrated, and your team is running live finite-capacity schedules before the end of week one. Compare that to 12–18 months for a full Epicor Kinetic rollout.
Frequently asked questions
Is RMDB a replacement for Epicor?+
RMDB replaces the scheduling and production planning layer of Epicor — specifically the finite-capacity APS functionality. It does not replace Epicor financials, HR, CRM, or supply chain. Many manufacturers use RMDB alongside an existing ERP (including Epicor products like JobBOSS) so they get best-in-class scheduling without ripping out the rest of their software stack.
Does RMDB integrate with Epicor or Epicor JobBOSS?+
Yes. RMDB integrates with Epicor Kinetic, Epicor JobBOSS, and other Epicor products via API or file-based exchange. Production orders, work centers, BOMs, and routings flow into RMDB for scheduling, and schedule results flow back. You keep Epicor for what it does well and add RMDB for finite-capacity scheduling depth.
Why would I buy RMDB instead of just getting the Epicor APS module?+
Three reasons: cost, time, and fit. Epicor APS requires a full Epicor Kinetic implementation — you cannot buy the scheduling module standalone. That means $50,000–$200,000+/year and 12–18 months before you see a finite-capacity schedule. RMDB starts at $5,000 one-time and goes live in 5 days. And RMDB is purpose-built for scheduling in a way a module inside a generalist ERP cannot match.
What size manufacturer is RMDB right for?+
RMDB is built for job shops and make-to-order manufacturers with 10 to 500 employees. Customers include GE, Cummins, and BAE Systems divisions alongside single-location machine shops. Epicor Kinetic is typically a better fit for manufacturers over $20M revenue with 100+ employees who need enterprise-wide software consolidation.
Can I keep my current ERP and just add RMDB for scheduling?+
Yes, and this is the most common path. RMDB is designed to sit alongside your existing ERP — whether that is QuickBooks, Sage, Dynamics, Epicor, JobBOSS, SAP, or anything else. You do not need to replace your ERP to get finite-capacity scheduling. RMDB integrates with what you already have.
How long does RMDB implementation take compared to Epicor?+
RMDB uses a standard 5-Day Implementation Framework. Most manufacturers have a live finite-capacity schedule running before the end of week one. A full Epicor Kinetic implementation typically takes 12 to 18 months. If your scheduling problem is urgent, waiting 18 months is not a plan — it is a delay.
