Google Drive for Client Files: 3 Risks

Google Drive works well for internal teams sharing work in progress. For client files -- tax returns, contracts, deliverables, case files -- it creates three specific problems: permissions that are easy to misconfigure, files tied to an employee's Google account that leave with them, and a per-user billing model that grows with your headcount rather than your client base. A dedicated client portal solves all three.

The Permission Problem With Google Drive

When you share a Google Drive folder with a client, the default setting is often "anyone with the link" -- meaning anyone who receives that link can view, download, and forward it. A client shares it with their assistant. Their assistant shares it with a vendor. You have no visibility into any of it. For firms handling confidential documents, that exposure matters.

Sharing errors are easy to make, too. It takes one wrong click to send a folder invitation to a client's personal Gmail instead of their work account, granting access to the wrong person or confusing the client entirely. There is no per-file access log showing who opened what and when -- only basic Drive activity, visible to the folder owner.

Using Drive for clients also ties file access to their Google account. If a client forgets their Google password, switches accounts, or uses the wrong one, the sharing breaks -- and the back-and-forth takes up your time. More importantly, if you ever need to prove delivery -- that a specific client opened a specific document on a specific date -- Drive's activity logs give you folder-level events at best, not the per-file timestamp an audit or dispute requires.

For tax professionals, the stakes are formal: the IRS advises tax professionals that protecting client data is the law -- federal regulations require tax preparers to create and enact security plans to protect client data. A folder shared on open-link settings would not meet that standard.

Files That Leave When Employees Do

Google Workspace's Shared Drives fix the ownership problem in theory: files in a Shared Drive belong to the organization, not the individual. In practice, this only works when every editor has a Workspace license and IT follows a clean-exit checklist every single time someone leaves.

A team member who stored client folders in their own Google Drive -- rather than in a Shared Drive -- takes those files when their account closes. Even when caught, the fix is manual: find every folder they owned or had edit access to, transfer ownership, then deactivate. One missed folder and a client's confidential documents sit in a closed account with no clean recovery path.

The Cost Math

Google Workspace Starter costs $7.00 per user per month (as of October 2026). A five-person firm pays $35/month for the infrastructure to share files. Each new hire adds another $7, regardless of how many clients you take on. Per-seat pricing works against you in a client-services business where revenue comes from clients, not headcount.

• Google Workspace Starter: $7.00/user/month (October 2026) -- a 5-person team pays $35/month
• Every new hire adds $7/month; adding 25 clients adds $0
• ProjectSend Cloud Pro starts at $19/month -- includes 3 seats and 25 active client accounts
• Same 5-person team on Pro: $27/month ($19 + two extra seats at $4 each)
• Adding a 26th client account: $0.40 -- adding a 6th team seat on Workspace: $7.00

What a Client Portal Does Differently

A dedicated client portal gives each client their own private area inside your branded portal -- not a shared folder they could accidentally navigate out of or forward to anyone. Every upload, download, and preview is logged with a timestamp: you can see exactly who opened which file and when. The security model covers encryption in transit and at rest, 2FA, and an audit log you can export -- without claiming certifications that don't exist.

Your files stay with your firm. When an employee leaves, their access ends; the client data does not move with them. And because ProjectSend is open-source under GPLv2 -- with 2,000+ stars on GitHub (2024) -- you can migrate to a self-hosted setup at any time. The code is open. So is your exit.

Switching isn't complicated. Email attachments and file-sharing tools each have their own tradeoffs worth understanding before you choose a replacement.

When to Switch From Drive to a Client Portal

Google Drive still makes sense for internal collaboration, shared documents your team edits together, and files that never leave the organization. A client portal becomes the right choice when:

• You send confidential files to external clients regularly -- tax returns, contracts, financial statements, case files
• You need a record of who downloaded which file and when (audit trail for compliance or disputes)
• You want your brand -- logo and colors -- on the portal your clients log into, not a Google-branded folder
• Client files need to stay with the firm when an employee leaves -- without a manual cleanup process
• You want to pay per client account, not per team member -- so your costs grow with client revenue, not headcount
