Put an end to daily sorting, scanning, and forwarding

Today

Letters are opened and distributed by hand
Every day, someone has to sort post, scan documents, and carry them around the office.
Email attachments scattered across inboxes
Invoices and contracts are stuck in personal inboxes, and no one has an overview.
Documents reach the relevant people too late
Days pass between receipt and processing, and tasks are left sitting idle.
No centralised filing system
Paper in folders, PDFs on the file server – nothing is searchable or auditable.
