Approval Workflow
From part creation to approved BOM — every step is controlled, traceable, and auditable.
Traditional PLM software costs 10–100× more. Lite PLM delivers the core functionality manufacturing teams actually use — at a fraction of the price.
Centralized repository for all parts, components, and sub-assemblies. Images, supplier data, SAP and Customer PN cross-references included. The single source of truth for all your manufacturing parts.
Build complete Bill of Materials parent-child structures with unlimited depth. Expand, collapse, add, edit, and delete — all in a clean BOM tree interface built for engineers.
Draft and Approved states enforced at all times. Clone previous revisions. Lock approved BOMs no unauthorized edits, ever. Full BOM version control for every product.
Raise Engineering Change Notices (ECN) and Change Requests (ECR) with auto-generated CN numbers, priority, impacted parts, and reviewer assignment before any revision is created.
Two-level sequential approval routing — Reviewer 1 must approve before Reviewer 2 is notified. Real-time status: Pending, Approved, Rejected. Full BOM approval process control.
Side-by-side BOM revision comparison with color-coded diff - Added (green), Removed (red), Modified (yellow). Instant clarity across any two BOM revisions.
Every BOM change, approval, and rejection is permanently logged with timestamp and user. Filter by date, part, or action type. Full traceability for manufacturing compliance.
Export BOM to PDF via Power Automate. Custom layouts, your logo, your columns — fully configurable. Automate BOM release notifications and downstream ERP updates.
Create Parts
Add parts to the Part Master with all metadata — number, description, supplier, UOM, SAP reference, and image. Every component in one searchable database.
Build Multi-Level BOM
Assemble multi-level Bills of Materials in draft mode. Add, edit, and arrange parent-child structures freely until your BOM is complete and ready for review.
Approve & Lock Revision
Submit for two-level BOM approval. Reviewer 1 signs off, then Reviewer 2. BOM is locked and released on final approval — no unauthorized changes possible.
Raise ECN & Revise
Need changes? Raise an approved Engineering Change Notice (ECN/ECR) first — then create the next revision, cloned from the last approved BOM. Full audit trail maintained.
One-time setup fee + optional Annual Maintenance Contract (AMC). No per-user PLM licensing — deploy to your entire organisation on Power Apps & SharePoint.

Everything you need to know about PLM software, BOM management, and Lite PLM
Lite PLM is an affordable Product Lifecycle Management (PLM) software built natively on Microsoft Dynamics 365, Power Apps, and SharePoint. It provides complete Bill of Materials (BOM) management, revision control, Engineering Change Notice (ECN/ECR) workflows, two-level approval routing, where-used impact analysis, BOM comparison, and audit trails — all without per-user licensing fees. It's designed for small to mid-sized manufacturers who need serious change control without the cost of traditional PLM systems.
Lite PLM by Apptomax is one of the best BOM management tools for small and mid-sized manufacturers. It runs on Microsoft Power Apps and SharePoint — platforms your team likely already pays for — and offers multi-level BOM creation, revision control, engineering change management, and approval workflows. The Professional plan starts at a one-time setup fee of $899 USD with no per-user fees, making it significantly more affordable than Arena PLM, Siemens Teamcenter, or PTC Windchill.
An Engineering Change Notice (ECN) — also called an Engineering Change Request (ECR), Change Notice (CN), or Engineering Change Order (ECO) — is a formal document that initiates and tracks a change to a product's design or BOM. Lite PLM auto-generates CN numbers, captures priority level, impacted parts, and reviewer assignments. Crucially, no new BOM revision can be created without a first approved CN, ensuring every BOM change is traceable and documented.
Lite PLM is built on Microsoft Power Apps and SharePoint, which are included in most Microsoft 365 business plans. It also integrates with Microsoft Dynamics 365 for ERP cross-referencing. No additional PLM software license is required — Lite PLM is deployed on top of tools your organization likely already subscribes to, keeping total cost of ownership very low.
A multi-level Bill of Materials (BOM) is a hierarchical list of all components, sub-assemblies, and raw materials needed to manufacture a product, showing parent-child relationships at every level. For example: a Laptop Assembly contains a Motherboard sub-assembly, which in turn contains a Processor, RAM, and other components. Lite PLM supports unlimited-depth multi-level BOMs with full expand/collapse tree navigation, making it ideal for complex manufactured products with many layers of sub-assemblies.
Where-used analysis (also called impact analysis) is a PLM feature that lets you search for any component part and instantly see every assembly, sub-assembly, and BOM revision that uses it. This is critical for assessing the full scope of an engineering change before making it — for example, if you're changing a connector part, you can immediately see all 12 products that use it. Lite PLM includes a built-in Where-Used module accessible from the Part Master.
Traditional enterprise PLM software like Siemens Teamcenter, PTC Windchill, or Arena PLM can cost $5,000–$100,000+ per year in per-user licensing and implementation. Lite PLM offers an affordable alternative: a one-time Professional setup fee of $899 USD plus an optional $49/month AMC, with no per-user fees. Your entire organization accesses it through Power Apps and SharePoint — making it one of the most cost-effective PLM solutions for small manufacturers.
The Professional plan of Lite PLM supports SAP Part Number and Customer PN cross-referencing within the Part Master, letting you map your PLM part numbers to SAP material codes. The Enterprise plan includes full SAP/ERP integration — bidirectional synchronization of BOMs, parts, and change orders between Lite PLM and your ERP system. Contact us to scope your specific SAP integration requirements.
Yes. Lite PLM is specifically designed to support the document and change control requirements common in ISO 9001, IATF 16949 (automotive), and AS9100 (aerospace) certified environments. Key compliance features include: locked approved BOMs (no unauthorized edits), mandatory Engineering Change Notice (ECN) before any revision, two-level approval workflow with full signoff records, permanent audit trail with timestamp and user for every action, and where-used impact analysis before changes are made.
What industries is Lite PLM designed for?
Lite PLM is used by manufacturers across electronics, automotive components, aerospace sub-assemblies, industrial equipment, consumer goods, medical devices, and capital goods. Any company that designs and manufactures a product with a structured BOM — and needs to manage revisions and engineering changes in a controlled, auditable way — is a fit for Lite PLM.
