Split second-round shipping across every order, down to the last won.

Paste your order list, enter what the forwarder actually charged, and get a per-buyer amount that adds up to the invoice exactly, plus a settlement post you can paste straight into your group chat. Your roster stays in the browser, so the next round is one number.

Step 1

Your round

Write name, weight on each line. Grams by default; write kg for kilograms. Tabs, commas and semicolons all work, so a spreadsheet column pastes in directly.

Added on top of each buyer's shipping share. Leave at 0 if you do not charge one.

How it works

Paste the list, collect the right amounts

  1. Paste one line per order with the buyer's name and their weight or item count.
  2. Enter the forwarder invoice and pick the unit your buyers can actually transfer.
  3. Copy the settlement post, or download the PDF for the buyer who asks how you got their number.

Rounding is handled by the largest-remainder method, so the charged amounts add up to the invoice to the last unit instead of leaving you a few hundred won short.

FAQ

Before you use it

Is this free?

Yes. This version has no payment, no account, and no order limit below 300 lines per round.

Will the amounts really add up to my invoice?

Yes. Every share is computed in minor currency units and the rounding shortfall is handed out one unit at a time to the orders with the largest fractional remainder. The sheet states how far rounding moved any single order from its exact share.

Which split should I use?

Weight matches how forwarders actually bill, so it is the fairest for mixed order sizes. Item count is simpler to explain. Even is for rounds where every order is the same parcel.

Do I have to retype my buyers every round?

No. This round is kept in your own browser, so the next time you open the page the list, the currency and the rounding unit are still here. Change the invoice total and split again. Clear this round wipes it.

Is my order list uploaded?

No. The split runs entirely in this tab, and the saved round is stored in your browser only. Neither the list nor the amounts ever leave your device.
