🧾 Bill / GST Line Editor

Edit any bill line below — product name, qty, price, taxable amount (subtotal), HSN code, or GST rate — then click Save on that row. Editing a line always recomputes its CGST/SGST from the taxable amount and GST rate, and updates that bill's total automatically. Use Sync to pull the current HSN/GST rate straight from the product (handy for old bills billed before GST was set up) — or Sync All (range) to backfill every line shown at once.
