The Fabric Tracking Challenge
For fashion brands that manage their own production — whether in-house or through CMT (Cut-Make-Trim) units — fabric inventory tracking is fundamentally different from finished goods tracking. Fabric is a continuous material measured in metres, comes in rolls of varying lengths, and undergoes transformation through cutting, stitching, and finishing. Tracking it accurately from procurement to finished garment is one of the hardest problems in fashion operations.
In India, where most fashion brands source fabric from mills in Surat, Bhilwara, Erode, or Ludhiana, the challenge is compounded by quality variations between rolls, shrinkage after washing, and the gap between theoretical fabric consumption and actual consumption on the cutting floor.
Fabric Roll Tracking
Receiving and Inspection
Every fabric roll that enters your warehouse should be individually registered with the following data:
- Roll ID: A unique barcode-based identifier
- Fabric type and composition: 100% cotton, poly-cotton blend, silk, etc.
- Colour and lot number: Critical for colour consistency across garments
- Received length: Measured at your facility, not just taken from the supplier's invoice
- Width: Actual usable width after selvedge
- Quality grade: A/B/C based on your inspection — defects per 100 metres
- Supplier and purchase order reference
A manufacturer in Tirupur found a consistent 3–5% shortfall between supplier-invoiced lengths and actual measured lengths across their fabric rolls. Over a year, this amounted to over ₹12 Lakh in fabric they were paying for but never receiving.
Storage and Lot Management
Fabric storage requires lot discipline. Rolls from the same dye lot should be stored together and used together to prevent colour variation in finished garments. A kurta with a slightly different shade on the collar because it was cut from a different dye lot is a quality failure that leads to returns.
- Organise storage by fabric type, then by colour, then by lot number
- Use FIFO (First In, First Out) to prevent fabric from ageing in storage
- Monitor storage conditions — humidity and temperature affect fabric quality, especially for silk and natural fibres
- Conduct monthly physical counts and reconcile with your system
Bill of Materials (BOM)
The BOM is the recipe card for every garment you produce. It lists exactly how much of each material is needed to make one unit. A proper BOM for a kurta might include:
- Main fabric: 2.5 metres of cotton cambric
- Lining fabric: 0.8 metres of cotton voile (for the yoke)
- Interlining: 0.3 metres of fusible interlining (for the collar)
- Thread: 150 metres of matching polyester thread
- Buttons: 7 units of 14mm shell buttons
- Labels: 1 brand label, 1 care label, 1 size label
- Packaging: 1 poly bag, 1 hang tag, 1 barcode sticker
The BOM should include a wastage allowance — typically 5–10% for fabric, accounting for cutting waste, defective pieces, and end-of-roll losses.
BOM Accuracy and Cost Control
Your BOM directly determines your product cost. If your BOM says a kurta needs 2.5 metres of fabric but the cutting floor actually uses 2.8 metres, you are losing ₹30–₹50 per garment on that style alone. Multiply that across a production run of 5,000 units and the loss is ₹1.5–₹2.5 Lakh.
- Create the BOM during the sampling stage with accurate measurements
- Validate the BOM against actual consumption in the first production batch
- Update the BOM if actual consumption consistently differs from theoretical
- Track fabric utilisation percentage: (fabric in finished garments / fabric issued from store) x 100
Wastage Calculation and Control
Fabric wastage in Indian garment manufacturing typically ranges from 8% to 18%, depending on the garment type and cutting efficiency. Understanding where your wastage occurs is the first step to controlling it.
Types of Fabric Wastage
- Cutting waste: The fabric between pattern pieces that cannot be used. This is the largest component, typically 8–12%.
- End-of-roll waste: The last few metres of a roll that are too short to cut a full set of pattern pieces
- Defect waste: Sections of fabric with printing defects, weaving faults, or stains that must be discarded
- Shrinkage: Fabric that shrinks during pre-wash or finishing, reducing usable area
Investing in marker efficiency — the layout of pattern pieces on fabric before cutting — can reduce cutting waste by 2–4 percentage points. For a brand using ₹2 Crore of fabric annually, that translates to ₹4–₹8 Lakh in savings.
From Raw Material to Finished Goods
The transformation from fabric to finished garment involves multiple stages, and your tracking system should follow the material through each one:
- Fabric store: Raw material is received, inspected, and stored. Stock is measured in metres.
- Cutting: Fabric is issued against a production order, cut into panels. Track metres issued vs. panels received.
- Stitching: Panels become garments. Track units entering and exiting stitching, plus rejects.
- Finishing: Washing, ironing, labelling. Track units through each finishing step.
- Quality check: Final inspection. Units are graded as first quality, second quality, or reject.
- Finished goods store: Approved garments are packed and enter finished goods inventory. Stock is now measured in units.
Each stage transition should be recorded in your system. This creates a complete audit trail from fabric roll to finished garment and allows you to identify exactly where material or units are being lost in the process.
Technology for Fabric Tracking
Spreadsheets break down quickly when tracking raw materials through production. You need a system that supports dual units of measure (metres for fabric, units for garments), BOM-based material reservation, roll-level inventory with lot tracking, and production order management that links fabric consumption to finished goods output. A fashion ERP with built-in production tracking provides this foundation and connects your raw material inventory to your finished goods inventory in a single system.
