Receive stock, then enter the extras

What you'll see · App dashboard → Receipts
  • Received: Transfer #1042 · 3 SKUs · 240 units
  • Freight $1,180.00 · Duty $620.00 · Brokerage $0.00

Allocate and preview new costs

Choose how to spread the extras — by value, quantity, or weight. The workbench previews the new weighted-average unit cost for every line before anything is written, so you see the math first.

What you'll see · App dashboard → Workbench
  • Basis: value — $1,800 of extras spread in proportion to each line's invoice value
  • Widget A: $4.00 → $9.63 per unit (×120)
  • Widget B: $9.00 → $21.66 per unit (×80)
  • Widget C: $2.00 → $4.81 per unit (×40)
