The True Cost of Manual DSAR Processing: Why Spreadsheets Don't Scale

What Does a Single DSAR Actually Cost?

Handling Data Subject Access Requests manually costs more than many businesses expect. In our illustrative example below, staff time comes to about €260-€440 per request (about 8-13 hours at €35/hour, adding up the task times in the table). Your figures will differ, and that’s before you factor in the risk of errors that can lead to regulatory action.

Let’s break it down.

The Hidden Costs of Manual Processing

1. Staff time (illustrative)

A typical manual DSAR involves:

And that’s assuming nothing goes wrong.

2. Opportunity Cost

When your team spends 8+ hours on a single DSAR, they’re not:

• Serving customers
• Generating revenue
• Working on strategic projects

For a business receiving 5 DSARs per month, that’s 40-65 hours of productive time lost.

3. Risk of Errors

Manual processes lead to mistakes:

• Missed deadlines: Risk of DPC enforcement notices and fines
• Incomplete responses: Regulatory investigation costs
• Privacy breaches: Accidentally sharing third-party data

One error can cost more than years of DSAR processing.

4. No Audit Trail

When the DPC asks “how did you handle this DSAR from 18 months ago?” — what do you show them?

With manual processing, you’re relying on email threads and spreadsheets that may be incomplete, deleted, or impossible to find.

The Automation Advantage

In this illustrative example, a platform cuts the time from 8-13 hours to about 1-2 hours. This is an assumption, not a measured result.

Calculate Your Savings

Monthly DSARs: 5 Manual hours per DSAR: 10 Hourly cost: €35 Monthly manual cost: €1,750 (5 × 10 hrs × €35)

With a platform (assumed): Hours per DSAR: 2 Monthly cost: €350 (5 × 2 hrs × €35) + platform fee

Illustrative annual saving: about €16,200 after a Starter plan at €590 a year ex VAT (€1,400 a month saved × 12 = €16,800, minus €590), based on the assumptions above, not measured results. Starter allows 5 cases a month.

When Does Automation Make Sense?

Immediately if you:

• Receive more than 2 DSARs per month
• Have data in multiple systems
• Need to demonstrate compliance to clients or regulators
• Want to reduce legal/compliance risk

Consider it if you:

• Are growing and expect DSAR volume to increase
• Handle sensitive data (health, financial, HR)
• Operate in regulated industries

The Real Question

It’s not “can we afford DSAR automation?” — it’s “can we afford not to have it?”

One missed deadline. One incomplete response. One accidental disclosure. Any of these can cost more than a decade of platform fees.
