GST In Fabric Costing: Break-Even, Invoice, And Net Payable
A practical GST walkthrough for textile quotations: what to compute ex-GST, what to show on invoice, and how to track net payable.
Step 1: Finalize Ex-GST Cost
Your technical and commercial decision starts with ex-GST cost per meter. This is the real operating baseline.
Do not mix tax into base production economics while deciding structure or budget fitness.
Step 2: Add GST For Invoice View
Once ex-GST sell price is set, compute output GST and invoice value (inclusive GST).
Keep both views visible in one result panel so sales and accounts can align quickly.
Step 3: Estimate Net GST Movement
Net GST payable per meter is output GST minus input GST. If input exceeds output, you carry credit.
Tracking this at quotation stage reduces surprises during settlement cycles.
- Output GST = sell_price_ex_gst × gst_rate
- Input GST = break_even_ex_gst × gst_rate (simplified planning view)
- Net payable = output GST - input GST
