For container lessors
Container leasing software that bills from what really happened
Your boxes are out on hire, in depots and on the way back. Krak Stack follows each one from release to return and turns the dates into per diem invoices, without a spreadsheet in between.

What it does
Three things you stop doing by hand
Per diems retyped from emails
Free days and per diems counted per container from the pickup and drop-off dates, invoiced from them.
Returns you discover late
Returns with their progress, depot reports read for you, silent depots flagged.
No idea what a box really earns
The result of each lease and of each container over its life, rents and sale together.
