RMDB vs Cetec ERP: Open Cloud ERP vs Finite-Capacity Scheduling
Cetec ERP is a credible cloud ERP for small-to-mid manufacturers with predictable pricing and open architecture. RMDB is finite-capacity scheduling. Different focus, complementary scope.
The short answer
Cetec ERP is a strong fit for $1M–$50M manufacturers wanting cloud ERP with predictable per-user pricing. RMDB adds scheduling depth that Cetec's built-in scheduling does not match. Combination handles ERP + APS at small-shop economics.
Why this comparison matters
Cetec ERP differentiates on two axes: open architecture (rest APIs everywhere, customer can extend) and predictable pricing ($40-$60/user/month with no hidden tier upgrades). For small-to-mid manufacturers tired of opaque ERP pricing and locked-down systems, Cetec is genuinely appealing.
Cetec scheduling is functional for shops with sequential routings and basic capacity needs. It does not extend to finite-capacity APS — sequence-dependent setup, what-if scenarios, alternate routing logic are not part of its scope. For Cetec shops with growing scheduling complexity, the gap shows up as missed ship dates and reactive replanning.
RMDB adds finite-capacity depth and integrates with Cetec via its open APIs. The setup is unusually clean given Cetec's API-first design. For Cetec shops where scheduling has become the constraint, the combination is a focused upgrade that preserves Cetec's small-shop economics.

Cetec ERP
$40–$60/user/month
Predictable per-user subscription
Cetec is one of the most pricing-transparent ERPs in the market: $40–$60/user/month for the entire system. A 20-user shop runs $10K–$14K annually. RMDB at $5K–$20K one-time covers the scheduling depth. Combined approach is one of the lowest total-cost options in the small-to-mid manufacturing space.
Where each tool wins
RMDB does this better
- Cetec shops needing finite-capacity scheduling depth
- Operations with sequence-dependent setup complexity
- Manufacturers needing on-premise deployment (defense, IP-sensitive)
- Shops wanting one-time licensing for scheduling capability
- Operations needing alternate routing and what-if scheduling logic
Cetec ERP does this better
- Small manufacturers wanting cloud ERP with predictable per-user pricing
- Operations needing open APIs for custom integrations
- Shops new to ERP wanting transparent total cost
- Manufacturers preferring cloud-only deployment with built-in maintenance
- Companies valuing Cetec's specific UI and API-first design
Which one should you pick?
Choose RMDB if…
Cetec shops where scheduling depth has become the constraint, or shops $5M+ needing finite-capacity scheduling alongside existing ERP.
Choose Cetec ERP if…
Small-to-mid manufacturers $1M–$30M wanting cloud ERP with low per-user pricing, open APIs, and predictable cost — without enterprise platform complexity.
Switching from Cetec ERP to RMDB
A practical migration path that most manufacturers complete in days, not months.
- 1
Keep Cetec for ERP
Cetec continues handling estimating, work orders, costing, accounting, and customer-facing functions. Only scheduling moves to RMDB.
- 2
Configure Cetec API integration
Cetec's REST APIs make integration unusually clean. Work orders, routings, and BOMs flow into RMDB via API; completion data flows back the same way.
- 3
Configure RMDB scheduling logic
Define work centers, shift calendars, setup time rules. Cetec routing data populates the constraints automatically.
- 4
Parallel run for 2 weeks
Compare RMDB schedule against Cetec's built-in output. Validate against shop floor reality.
- 5
Transition fully
Move scheduling to RMDB. Cetec scheduling unused; Cetec subscription continues for ERP value.
Frequently asked questions
Is Cetec really only $40–$60/user/month?+
Yes, that is Cetec's public pricing. There are some module add-ons that extend the price but the base ERP is genuinely in that range. This pricing transparency is unusual in the manufacturing ERP market.
How does Cetec's open API help with RMDB integration?+
Significantly. Most ERPs require direct database access or vendor-built integrations. Cetec's REST APIs are documented and stable, which makes RMDB integration faster to build, easier to maintain, and less dependent on Cetec internals.
Can Cetec handle complex scheduling on its own?+
Not really. Cetec scheduling is functional for sequential routings and basic capacity loading. It is not finite-capacity APS. Cetec's strength is the rest of the ERP — scheduling is the area where adding a specialized tool (RMDB or similar) is most often beneficial.
Is Cetec a good choice for very small shops?+
Yes — Cetec scales down well to 5–10 employee operations because of the per-user pricing model. Small shops that need ERP but cannot justify $20K+ annual subscriptions find Cetec genuinely accessible.
What is the total Cetec + RMDB cost for a 20-user shop over 5 years?+
Cetec at $50/user/month × 20 users × 60 months = $60K. RMDB $10K one-time + $1.5K/year support × 5 = $17.5K. Combined ~$77.5K — one of the lowest total-cost options in the small-mid manufacturing scheduling space.
