Everyday
This chaos sound familiar?
Mivly turns that chaos into order.
Warehouse says one thing, sales another?
Orders go out while issues and stock catch up later. Shortages show up at picking, not at the quote.
Invoices and KSeF lost in the inbox?
Due dates, e-invoice status and overdue amounts live in email or in accounting's head? The dashboard shows what needs action today.
Dashboard
Start the day knowing what needs a decision.
The day inbox gathers signals from the whole company: invoices for KSeF, overdue payments and orders waiting for a move.
