Revision or creation of an order portal

For our daily incoming and outgoing orders, we need assistance with an order portal. Currently we use an online exel table - so that it can be viewed on every computer. We would be grateful for assistance in revising or even developing a simple app or program. The following criteria should be met: - self-updating -> at least every 15 minutes - several users need access (at least 4 at the same time) - Orders should be sorted automatically according to the latest delivery date - automatic data backup on server - copy as pdf / xls on server - Reminder 2 hours before exit (that courier must be ordered) - Search field for patient names (search in all orders incl. Not visible archive) - Linking to folders on server "Farbnahme"
