LillyWorks Review: Pricing, Features, Pros and Cons

LillyWorks is a manufacturing-focused ERP built around a single, differentiating idea: shop floor scheduling should be dynamic, not static. While most ERP systems rely on traditional infinite or finite scheduling algorithms that break down the moment a machine goes offline or a material shipment runs late, LillyWorks uses its proprietary Protected Flow Manufacturing (PFM) methodology to reprioritize work in real time. For small and mid-sized make-to-order manufacturers, this approach can be transformative.

But LillyWorks is not a full-featured, do-everything ERP. It lacks HR and payroll modules entirely, and its broader functional depth outside of production planning and financials is limited compared to established players like Epicor or Infor. The question for any prospective buyer is whether LillyWorks’ scheduling intelligence and fast implementation offset what it doesn’t do. For the right shop, the answer is often yes.

What Is LillyWorks?

LillyWorks is a cloud-based ERP platform designed specifically for make-to-order and job shop manufacturers. The company was founded by the Lilly family, whose manufacturing software roots stretch back to the 1960s. Dick Lilly launched VISUAL Manufacturing in 1991, one of the early Windows-based manufacturing ERP systems. The current generation, brothers Mark and Michael Lilly alongside partners David Layne and Scott Filiault, built LillyWorks around a methodology they call Dynamic Production Method (DPM), which encompasses three principles: Pragmatic Planning, Proper Pacing, and Predictive Prioritization.

Headquartered in Hampton, New Hampshire, LillyWorks is a small, privately held company with an estimated 10 to 50 employees. It serves roughly 70 customers, primarily small to mid-sized manufacturers in sectors like electronics, machinery, and metal fabrication. The company offers two products: PFM as a standalone scheduling tool that integrates with an existing ERP, and PFM Enterprise, a complete ERP solution combining production planning with financial management. The vendor claims over 55 years of manufacturing software development heritage, and blog activity through early 2026 confirms ongoing product development.

LillyWorks Key Features

Protected Flow Manufacturing (PFM) Scheduling

This is the core differentiator. PFM replaces traditional scheduling algorithms with a threat-level prioritization system that constantly recalculates which job is most critical at any given moment, across any work center, machine, person, or tool. Rather than generating a static schedule that immediately starts degrading, PFM dynamically adjusts as conditions change on the shop floor. The system uses demand-driven MRP (DDMRP) algorithms to manage material flow, aiming to reduce work-in-progress (WIP) while improving on-time delivery. LillyWorks claims clients achieve 90% to 100% on-time delivery rates using this approach.

Job Simulation

LillyWorks includes a predictive simulation engine that can model hundreds of work orders in minutes. This lets production managers test “what-if” scenarios before committing to a plan: what happens if a machine goes down, a rush order comes in, or a supplier delivers late. The vendor describes this as predictive AI, though the specifics of the underlying technology are not detailed on their website. For shops that frequently deal with shifting priorities and surprises, this capability addresses a real pain point that most traditional ERPs handle poorly.

Real-Time Shop Floor Visibility

The system provides real-time WIP status and costing data, giving production managers and shop floor personnel live visibility into where every job stands. A visual flowchart interface maps the production process, making it straightforward to follow job progress through each routing step. The system also functions as a “GPS” analytics tool, identifying delays, bottlenecks, and material shortages before they derail the schedule. Automated job release controls maximize material flow by releasing work only when the shop floor is ready for it.

Bill of Materials and Shop Floor Routings

LillyWorks supports both convergence product structures (multiple subassemblies coming together into a finished product) and divergence structures (parts separating to different routings). This flexibility matters for manufacturers with complex assemblies or those producing byproducts. The system handles unit of measure conversions between operations and provides standard BOM and routing definition tools. These are table-stakes features for manufacturing ERP, but LillyWorks implements them within the context of its PFM methodology, so routing data feeds directly into the dynamic scheduling engine.

Financials Module

PFM Enterprise includes a full financial management module covering sales orders, shipping and invoicing, returns and credits, payment allocations, purchase orders, receiving, and three-way matching. Additional financial capabilities include a configurable chart of accounts, credit card payment processing, banking integration, financial budgeting, commission tracking, and “as of” aging reports. The module provides drill-down reporting for both customer and supplier data. It can operate as a standalone financial system or with configurable integration into the production side of the platform.

Quoting and Estimating

The system includes tools for RFQs (requests for quote), quoting, and estimating. One implementation review highlighted that users discovered significant product costing issues during the go-live process, suggesting the quoting and costing tools surface pricing inaccuracies that may have gone undetected in prior systems. For job shops where accurate quoting directly affects margins, this functionality is critical.

Customer Inquiry Portal

LillyWorks includes a customer inquiry portal that gives your clients direct visibility into order status without requiring phone calls or emails to your team. This is a feature that many larger ERPs offer but that smaller manufacturing systems often lack. It can reduce administrative overhead and improve customer satisfaction, particularly for shops managing dozens or hundreds of active orders.

Mobile Access

As a web-based SaaS application, LillyWorks is accessible from any device with a browser, including smartphones and tablets. The vendor also offers a dedicated iOS mobile app (LillyWorks PFM Mobile). However, the mobile app experience is a weak point: it carries a 1.0 out of 5.0 rating on the Apple App Store, with the sole review reporting constant crashes. Browser-based mobile access appears to be the more reliable option at this time.

LillyWorks Pricing and Plans

LillyWorks does not publish pricing on its website. The vendor uses a subscription-based, per-user-per-month pricing model, and quotes are customized based on company size, module selection, and deployment scope. Annual commitment plans with automatic product updates are available.

Third-party sources report varying price estimates, which likely reflect differences between the PFM standalone product and PFM Enterprise, as well as volume discounts:

These figures come from third-party review platforms and should be confirmed directly with LillyWorks. The wide range ($30 to $100 per user per month) suggests that pricing depends heavily on which product you select (PFM standalone vs. PFM Enterprise) and the size of your deployment. No free plan exists. Free demos are available upon request, but a self-service free trial has not been confirmed in current sources.

The vendor emphasizes low upfront costs relative to traditional on-premise manufacturing ERP systems. For a 20-user deployment at an estimated midpoint of $75/user/month, you would be looking at roughly $18,000 per year in subscription fees before implementation costs. That is significantly less than deploying a system like Epicor or Infor, though the scope of functionality is also narrower.

Integrations

One of LillyWorks’ strategic strengths is its ability to work alongside existing ERP systems rather than requiring a full rip-and-replace. The PFM standalone product is specifically designed as a scheduling overlay that connects to your current ERP via a standard connector. The vendor lists compatibility with the following platforms:

• Epicor
• IQMS (now DELMIAworks)
• Infor SyteLine
• Infor M1
• Microsoft Dynamics
• Sage
• Oracle
• Plex
• Acumatica
• Salesforce
• QuickBooks

LillyWorks states it offers a “standard connector for most manufacturing ERP” systems, which suggests a pre-built integration framework rather than custom point-to-point connections for each platform. One third-party source reports that LillyWorks does not support a public API, which may limit custom integration options for shops with homegrown systems or less common ERP platforms. We recommend confirming API availability directly with the vendor if custom integration is a requirement for your environment.

There is no mention of Zapier, Make, or other middleware platform support in any of our research.

Customer Support

LillyWorks offers phone, email, and chat support, included as part of the standard subscription contract. Training is available both online and onsite, and the vendor provides a dedicated implementation team for new deployments.

Support quality is one of LillyWorks’ clear strengths. The implementation team is described as “extremely supportive,” and the onboarding process covers core workflows including order entry, engineering models (BOM and routings), RFQs, purchase orders, build/ship processes, and inventory management. Online training is structured and appears thorough enough that customers can get operational without requiring expensive consultant-led implementations.

The company’s small size cuts both ways here. On the positive side, customers get direct access to people who know the product deeply, rather than being routed through tiered support queues. On the other hand, a 10-to-50 person company has limited support capacity, and response times during peak periods may vary. Support appears to be English-only.

Pros and Cons

LillyWorks delivers real value in a narrow but important area of manufacturing operations. Here is where it excels and where it falls short.

Who Should Use LillyWorks?

Best fit: Small to mid-sized make-to-order manufacturers and job shops with 10 to 200 employees who struggle with on-time delivery, excessive WIP, and shop floor scheduling chaos. If your current ERP generates a schedule that is obsolete by mid-morning, LillyWorks’ PFM approach directly addresses that problem. Metal fabrication shops, electronics manufacturers, and custom machinery builders are the vendor’s sweet spot.

Also consider LillyWorks if: You already have an ERP system you are reasonably happy with but need better production scheduling. The PFM standalone product lets you keep your existing financial and operational systems while adding dynamic scheduling on top. This is a lower-risk, lower-cost entry point that avoids a full ERP migration.

Not a good fit for: Manufacturers who need a comprehensive, all-in-one ERP with HR, payroll, advanced warehouse management, or deep e-commerce capabilities. LillyWorks does not cover these areas. Companies with more than a few hundred employees may find the platform’s scope too limited, and organizations in process manufacturing (food, chemicals, pharmaceuticals) rather than discrete manufacturing should look elsewhere. Additionally, if your team relies heavily on mobile apps for shop floor data entry, the current state of the iOS app is a concern.

LillyWorks Alternatives

JobBOSS2

JobBOSS2 by ECI Software Solutions is a direct competitor targeting the same job shop and make-to-order audience. It offers broader ERP functionality out of the box, including more mature quoting and estimating tools and a larger customer base. However, it uses traditional scheduling methods that lack LillyWorks’ dynamic PFM approach. Choose JobBOSS2 if you need a more full-featured job shop ERP and are willing to sacrifice scheduling sophistication.

Epicor Kinetic

Epicor Kinetic is a far more comprehensive manufacturing ERP covering everything from financials to HR to supply chain management. It serves mid-market manufacturers who need deep functionality across the business. The tradeoff is cost and complexity: Epicor implementations typically take months and cost significantly more. If you have outgrown LillyWorks’ scope or need enterprise-grade capabilities, Epicor is the logical step up. Notably, LillyWorks’ PFM can integrate with Epicor, so some shops use both.

Plex by Rockwell Automation

Plex is a cloud-native manufacturing ERP with strong shop floor control, quality management, and supply chain capabilities. It is better suited for larger manufacturers (200+ employees) and those in regulated industries requiring traceability. Plex costs more and requires more implementation effort, but its functional breadth dwarfs LillyWorks. Consider Plex if your manufacturing complexity and company size justify the investment.

MIE Trak Pro

MIE Trak Pro targets small job shops and offers a tightly integrated manufacturing ERP with scheduling, quoting, quality, and inventory in a single system. It is simpler and more affordable than enterprise options, putting it in the same weight class as LillyWorks. MIE Trak Pro has broader general ERP features but lacks LillyWorks’ unique dynamic scheduling methodology. It is a solid alternative if you want a more traditional, all-in-one approach for a small shop.

Infor CloudSuite Industrial (SyteLine)

Infor CloudSuite Industrial is a mature manufacturing ERP with particularly strong planning and scheduling capabilities, including advanced planning and scheduling (APS) add-ons. It handles mixed-mode manufacturing environments better than LillyWorks and offers significantly more depth in financials, CRM, and supply chain. However, it is more expensive, more complex to implement, and takes longer to deliver ROI. Like Epicor, LillyWorks’ PFM can integrate with SyteLine, making them complementary rather than strictly competitive.

Frequently Asked Questions

What is Protected Flow Manufacturing (PFM)?

PFM is LillyWorks’ proprietary scheduling methodology that replaces traditional ERP scheduling algorithms with a dynamic, threat-level prioritization system. Instead of generating a fixed schedule, PFM continuously recalculates which jobs are most critical based on real-time shop floor conditions, material availability, and due dates. The goal is to reduce WIP, eliminate bottlenecks, and improve on-time delivery.

Can LillyWorks work with my existing ERP system?

Yes. LillyWorks offers PFM as a standalone scheduling product that integrates with most major manufacturing ERP systems, including Epicor, Infor SyteLine, Infor M1, Microsoft Dynamics, Sage, Oracle, Plex, Acumatica, and QuickBooks. A standard connector is available for most platforms. This allows you to add dynamic scheduling without replacing your current ERP.

How long does LillyWorks take to implement?

Implementation timelines vary by source and scope. Third-party estimates range from 2 to 4 weeks for small businesses deploying PFM standalone, up to 2 to 3 months for full PFM Enterprise implementations. This is significantly faster than most traditional manufacturing ERP deployments, which often take 6 to 12 months or longer.

Does LillyWorks offer a free trial?

A self-service free trial is not currently confirmed. The vendor does offer free demos upon request. Contact LillyWorks directly to discuss demo options and any trial arrangements that may be available for your specific situation.

What industries is LillyWorks best suited for?

LillyWorks is designed for discrete, make-to-order manufacturing and job shop environments. It is particularly well suited for electronics manufacturing, machinery production, and metal fabrication. It is not designed for process manufacturing industries such as food and beverage, chemicals, or pharmaceuticals.

Does LillyWorks include financial management features?

The PFM Enterprise product includes a full financials module with sales orders, purchase orders, invoicing, payments, three-way matching, banking, budgeting, and configurable chart of accounts. The PFM standalone product does not include financials and is intended to work alongside an existing ERP’s financial system.

Is LillyWorks cloud-based or on-premise?

LillyWorks is a cloud-based SaaS application accessed through a web browser. There is no on-premise deployment option. This means no server hardware to maintain, automatic updates, and access from any location with internet connectivity. A dedicated iOS mobile app also exists, though its current quality is questionable based on App Store feedback.

The Bottom Line

LillyWorks occupies a unique position in the manufacturing ERP market. Its Protected Flow Manufacturing methodology is genuinely different from what you will find in traditional scheduling tools, and for shops where on-time delivery and WIP reduction are urgent priorities, it can deliver measurable results quickly. The ability to deploy PFM as a standalone scheduling layer on top of an existing ERP is particularly smart, lowering the risk and cost of adoption.

The limitations are real, though. This is a narrow product from a small company. No HR, no payroll, a troubled mobile app, and a feature set that several reviewers have called thin outside of its scheduling core. If you need a comprehensive ERP that covers every business function, LillyWorks is not it. But if your shop floor is where the pain is, and you are tired of static schedules that fall apart before lunch, LillyWorks deserves serious evaluation.

We rate LillyWorks 3.7 out of 5 overall. It is excellent at what it focuses on, but its limited scope, small vendor size, and gaps in broader ERP functionality keep it from competing with more complete solutions. For make-to-order manufacturers with 10 to 200 employees who prioritize production scheduling above all else, it is one of the most targeted and effective tools available.
