Free Document Management System – Google Sheets Apps Script

A document register for organisations that hold papers with dates on them — certificates, licences, contracts, compliance files — where the question is always the same: whose document is this, and when does it expire.

Company decides what you see

Every login belongs to a company. When a user uploads a document, the company and the uploader's name are stamped onto the record automatically, so nobody can file a document under someone else's company by accident or otherwise. Users see their own company's documents; the admin sees every company's. For a group with several subsidiaries, or an agency handling several clients, that is the whole access model in one column.

Documents and their files

Each record carries a document ID, a name, an issue date and a due date, with the file itself uploaded to your own Google Drive folder while a progress indicator runs. Editing a record can also replace the attached file, and deleting asks first.

Filters that build themselves

The company filter is not a list you maintain — it is assembled from the users that exist, so creating a user under Company C makes Company C appear as a filter option the next time the page loads. A date range filter sits alongside it, which is how you pull everything falling due this month.

Setup

Create a Drive folder, paste its folder ID into the script, and the uploads land there under your own account. The register itself lives in your Google Sheet.
