Bullows Paint Equipment ERPNext Implementation
Precision in Production: Transforming Project and Product Planning for Bullows Paint Equipment
Manufacturing
Key Results Achieved
The Challenge: Spreadsheet-Driven Planning with No Visibility
Multiple parallel projects, resource conflicts, and blind production scheduling made reliable delivery nearly impossible.
Unclear Project Priorities
Multiple construction projects were being run in parallel without clear visibility into which ones were critical and which could flex. This led to poor prioritisation, missed deadlines, and little clarity on project profitability or the true status of active sites.
- Poor project prioritisation
- Missed deadlines
- No clarity on project profitability
Constant Resource Crunch
There was no structured way to assess how limited resources would impact delivery timelines. Teams were repeatedly pulled in different directions, creating ongoing resource conflicts without understanding the real cost or trade-offs of those decisions.
- No resource impact assessment
- Ongoing resource conflicts
- Hidden trade-off costs
Blind Production Scheduling
Standard production practices ignored demand swings, buffer requirements, and realistic lead times. It was nearly impossible to predict when finished goods would be ready or identify which materials were genuinely constraining production.
- Ignored demand swings
- No buffer requirements
- Unrealistic lead times
Overreliance on Excel
Project planning and MRP were heavily dependent on spreadsheets, which were time-consuming to maintain and often outdated by the time reports were completed. There was no single, integrated view of material status and no automated triggers for reordering.
- Time-consuming spreadsheets
- Outdated reports
- No automated reorder triggers
No Material Visibility
There was little to no insight into what needed to be produced in advance, where true shortages existed, or where buffer stock was held. This led to production stoppages, last-minute purchasing, and frustrated customers waiting on delayed orders.
- Production stoppages
- Last-minute purchasing
- Delayed customer orders
Business Impact Before Implementation
Benefits
Structured project and production planning replacing spreadsheet chaos
Realistic Project Scheduling with Critical Path & Critical Chain: Implemented an advanced planning engine combining critical path and critical chain. Project-level buffers replaced task-level padding, resulting in far more realistic and reliable schedules.
Clear, Visual Project Tracking: Rolled out Gantt charts highlighting critical and feeding paths, along with fever charts that show resource load across the critical chain. Management could instantly see what was at risk and where to focus.
Theory of Constraints-Driven Manufacturing Planning: Designed a TOC-based MRP system where demand is driven by actual customer orders. Buffer items are pre-built and ready, and lead times reflect real production capability.
Smart Buffer Management: Set up automatic reorder triggers at the item level using clear Green, Yellow, and Red zones. This removed manual guesswork and helped prevent material shortages before they disrupted production.
Priority-Based Material Planning: Introduced Required By logic that explodes BOMs and sequences materials based on manufacturing priority. Planning runs automatically when buffers are checked and can also be triggered manually based on sales order urgency.
End-to-End Visibility Through Reporting: Delivered 20+ custom reports covering MTO shortages, Sales Order and Work Order full-kit status, real-time material availability, and buffer health with color-coded indicators.

Testimonial
Feedback from Bullows Paint Equipment management.
When we started working with Yagna and Hybrow Labs, our Purchase and Production planning at Bullows Equipment was largely managed through Excel sheets. It worked for a while, but as we grew, it became increasingly difficult to track priorities, ensure timely material availability, and coordinate across departments.Yagna's team introduced us to a Theoy of Constraints (TOC)-based Material Planning Module, and the change has been remarkable. The system provides complete visibility into what to buy, what to produce, and what to prioritize all in real time. Our Purchase and Production teams now work in sync, with far fewer follow-ups and much greater clarity. The module is an integral part of ERP Next (our ERP system)The implementation has replaced spreadsheets with a robust, system-driven approach that helps us manage flow across operations with ease. It's practical, effective, and has already made a measurable difference in how we plan and execute our Work.What we appreciate most about Yagna is their hands-on approach they didn't just install TOC, ERPNext a system; they made sure it worked for our reality. Their deep understanding of and their commitment to results truly stand out.We're happy to recommend Yagna and Hybrow Labs to any organization looking to bring focus, visibility, and flow to their material and production planning processes for results.
