Usage Difference = Total Issued to Kiosk − Closing. Enter the month's total issuance, adding up every delivery if the item went out in several drops. If you already know the usage figure, type it into the last column and it overrides the calculation.

Export one file per branch from Sortly and drop it here. The quantity column becomes Total Issued to Kiosk for the month you pick. Nothing is written until you have seen the summary and pressed Import.

Every account here has the same full access — the issuance figures, the usage entry, the item list and prices, and both branches. Give one to each manager rather than sharing yours, so you can see who is signed in and remove an account when someone leaves.
