Upload a Bill of Entry PDF to see product/HSN/cost/duty data as a table, then export what you need.
Add freight, insurance, handling, etc. Each is split across every item below, in proportion to that item's assessable value (falls back to INR invoice value) — so higher-value items absorb proportionally more of the shared cost. The result lands in the "landed_cost" column.
One Bill will be created per vendor invoice group below. Lines are booked by account, not by item, so stock on hand is never touched by this push. The SKU is still written into the line's name/description for reference; a matched SKU also gets categorized under that item's own purchase account instead of a generic one.
One Purchase Voucher will be created per invoice group below, dated to that invoice's own date. Each item's rate is unit price × exchange rate; the group's combined landed cost (from the panel above) is posted as one "Handling Charges" line, and the voucher number is set to the invoice number.
