ERPDrive for Fabrication Units & Job Shops
Run drawing-based, made-to-order fabrication with full revision control, welder qualification logging, and mill TC stacking - so every job ships with documents auditors actually accept.
The pain points generic ERP doesn't solve
Tally and BUSY handle accounting. SAP and Microsoft Dynamics need 4-month implementations. Neither is built for these specific fabrication units & job shops pain points:
Drawing and revision control across the shop
Customer sends drawing rev 3; cutting starts; rev 4 arrives mid-job. Without rev control at item + BOM + production order level, you weld to the wrong drawing and scrap a week of work.
Welder qualification and procedure logging
OEM and EPC customers require WPS (Welding Procedure Specification), PQR (Procedure Qualification Record), and welder qualification per ASME IX or ISO 9606. Excel spreadsheets get lost; auditors fail you.
Material certificate traceability (Mill TC → Product TC)
Customers want a TC stack: which mill plate went into which weldment, with chemical analysis and mechanical properties. Without lot-and-heat-linked inventory, this is a multi-day reconstruction job.
Sub-contracted operations (machining, plating, NDT, painting)
Heavy fab outsources machining of mating surfaces, hot-dip galvanizing, ultrasonic / radiographic testing, and painting. Each is a GST job-work transaction with challan, return, and ITC-04 implication.
Per-job costing for MTO/ETO work
Every job is different: 5-tonne weldment vs 50-tonne weldment, different drawing, different alloy, different welder hours. Quote-to-cost variance per job needs to be tracked, not aggregated.
Cutting plan optimization for plate stock
A 3m x 12m HR plate costs ₹2-5 lakh. Poor cutting plan wastes 8-15% as scrap. Manual nesting in AutoCAD is slow; optimal nesting needs an order book view.
The ERPDrive demo flow for your factory
Here is exactly what we will show you in a 30-minute demo. Every screen uses real industry workflows, not generic sample data:
- Drawing-based item master with rev control
Each fabricated item is keyed to a drawing number + revision. When the customer sends rev 4, you supersede rev 3 with a click; open production orders are flagged for review.
- Job/project BOM with cutting list
BOM for a 5-tonne weldment: 12mm HR plate (qty per cutting list), 8mm plate, structural beams, fasteners, welding consumables, paint. Cutting list shows nesting plan for plate optimization.
- Material inwards with Mill TC
When 10mm HR plate arrives from JSW, the Mill TC PDF is attached to the inwards. Plate lot and heat number are recorded. The TC moves with every cut piece downstream.
- Welder allocation + WPS log per joint
Production order has a welding plan listing every weld joint, the WPS to be used, and the qualified welder allocated. Welder logs in, scans the joint barcode, performs weld, marks complete. WPS + welder qual + date logged automatically.
- Sub-contract operation (machining + galvanizing + NDT)
After welding, the weldment goes to a machining sub-contractor. System generates GST challan, e-way bill, and tracks pending return. When it returns, receipt is captured; if galvanizing is next, the cycle repeats.
- TC consolidation at dispatch
On final dispatch, one click generates the TC stack: drawing rev, material Mill TCs (per piece), welder qualifications, WPS used, NDT report, dimensional inspection, FAT (Factory Acceptance Test) result. Customer-ready PDF in 30 seconds.
- Job-wise actual vs quote variance
Per project, the system shows quoted vs actual: material cost, welder hours, machining sub-contract, scrap, overhead. Variance > 5% triggers a review before next quote to that customer.
- E-way bill with all axles + multi-leg
Heavy fab dispatch often needs over-dimensional cargo (ODC) EWB. System calculates validity at 1 day per 20 km automatically and generates EWB with vehicle weight, dimensions, and route.
Modules tailored for fabrication units & job shops
Out-of-the-box features (no custom development needed):

"Job-wise costing changed how we quote. Earlier we were averaging across all jobs and slowly losing margin on the complex weldments. Now we see quote-vs-actual per job and the complex jobs are repriced. Three of our recurring product variants got a 12% price correction last quarter without losing a single customer."Measured outcomes
- Per-job margin variance visibility (3 product variants repriced +12%)
- Sub-contract pending challans 24 → 3 (closed the open ones)
- Customer TC stack delivery: 2 days → same-day dispatch

Frequently asked questions
How does drawing revision control work in ERPDrive?
Each item is keyed to a drawing number + revision. When the customer sends a new rev, you create the new rev as a child of the old one. Open production orders, quotations, and inventory referencing the old rev are flagged. You decide whether to supersede or run both in parallel.
Does ERPDrive support welder qualification per ASME IX?
Yes. Welder masters store qualifications by process (SMAW, GTAW, GMAW, FCAW), position (1G/2G/3G/4G/5G/6G), base metal P-number, filler metal F-number, and expiry date. WPS library stores procedures. Production order auto-suggests qualified welders per joint.
Can ERPDrive track Mill TC from raw material to dispatched weldment?
Yes. Mill TC PDF is attached at material inwards along with plate lot and heat number. As plates are cut, welded, machined, and packed, the lot ID travels through. At dispatch, the TC stack PDF aggregates: Mill TCs (per piece) + welder qual + WPS + NDT + dimensional inspection.
How does the sub-contract module handle GST and EWB?
When you send a weldment to a machining sub-contractor, the system generates Form GST CHA challan + e-way bill in one screen. The challan is logged with the 1-year deemed-supply deadline. When the weldment returns, receipt closes the challan. ITC-04 quarterly is auto-generated.
How do we handle ODC (over-dimensional cargo) for heavy fab dispatch?
ERPDrive auto-detects ODC dimensions from item master and calculates EWB validity at 1 day per 20 km (vs 1 day per 200 km for normal cargo) per Rule 138(10). Vehicle Part B is entered once per shipment.
What is the typical implementation time for a fabrication unit?
1 week for a 50-150 employee single-location unit. We pre-load welder qual templates, common WPS, and standard structural item codes (ISMB, ISMC, ISA, plate grades) so master setup is template-driven.
Can ERPDrive run alongside our existing project management software?
Yes. ERPDrive handles items, BOMs, production, inventory, sub-contract, GST, dispatch. If you use a separate PM tool (MS Project, primavera) for milestones, we can integrate via API or run side-by-side with daily sync.
