    Why legacy breaks

    Operations don't break.The seams between tools do.

    When stock, releases, leasing, trading and invoicing live in different tools, every handover is retyped somewhere, and that is where errors creep in.

    Three things your spreadsheet cannot do

    Bank reconciliation that learns

    Connect Revolut Business or Airwallex, or import a statement. Each payment comes with ranked invoice proposals that improve with every match you validate. Only unambiguous matches are confirmed automatically.

    Depot stock reports, read for you

    Depots keep sending their stock report by email. Krak Stack reads it, matches each line to your inventory and shows what does not match.

    Per diems from the movements

    Free days are counted per container from the pickup and drop-off dates. The per diem invoice is built from those dates, not retyped.

    Yes. Krak Stack is built for the people who run container operations day to day: lessors, traders and mixed operators, not for administrators. Screens follow how the business already works, so teams learn it in days, with no legacy ERP experience required.

    That's the goal. Inventory, contracts, releases, returns and invoicing live on one shared record instead of a spreadsheet next to the screen, so there's less exporting, less re-entering the same data twice, and less time spent reconciling files between teams.

    Yes, and they share the same container registry. A unit can move between leasing and trading without re-keying data.

    Yes. Releases, returns, claims and invoicing are native modules on the same container record: a pickup or a drop-off updates the container, the deal and the per diems, and invoices are raised from the deal.
