AEO Quick Answer & Key Takeaway

Pre-costing is the estimated garment production budget created by merchandisers to quote buyer prices. Post-costing captures actual shop-floor consumption: extra fabric meters used due to marker inefficiency, operator overtime, and subcontract re-work. Werkora provides live order-wise cost reconciliation, highlighting margin leakage before orders ship.

Where Garment Margins Evaporate

Merchandisers celebrate closing export orders with a projected 18% gross margin based on cost sheets calculated in Excel. Months later, the annual P&L reveals that factory margins dropped to 4%. Because costs were never tracked order by order during execution, leadership cannot determine which styles drained profitability.

The Pitfalls of Static Excel Quotation Sheets

Static cost sheets rely on idealized assumptions: 100% cutting efficiency, zero rejection on printing, and baseline freight rates. On the production floor, small delays force expensive air-freight dispatches or secondary washing runs that wipe out profits.

Live Variance Analysis in Werkora

Werkora links purchase orders, cutting floor fabric issues, piece-rate wages, and job work bills directly to the specific buyer purchase order. Real-time cost dashboards display estimated versus actual cost per garment across fabric, trims, labor, and overhead.

Frequently Asked Questions

Expert Answers for Factory Operations

What is the primary cause of post-costing variances in apparel?

Excess fabric consumption caused by marker inefficiency, roll width variations, and unbudgeted cutting re-cuts is the single largest cost variance.

When should post-costing be reviewed?

Review post-costing progressively at cut completion, stitching completion, and final packing to catch cost overruns while orders are still on the line.
