The problem

No one has time to check every client for every claim.

The claims are real, and year after year they go unused. The specialists have the time — and charge 10–30% of whatever they recover.

The solution

From DATEV export to finished calculation.

For each client, staedy shows where there's money to recover — with the amount, an honest assessment, and a traceable rationale.

Retroactive

The first run surfaces what's been left behind across the open years.

Ongoing

Every export after that is checked — new entries, new deadlines, before they lapse.

With a draft

If you want, staedy drafts the client letter alongside it. You sign it off.

Privacy.
That's staedy.

It all runs offline, on your own computer. The browser just opens the file — no connection to the outside, no upload, no server, no account. staedy never sees your client data.

The upside

Value for your clients. A fee for your firm.

What staedy finds becomes billable work.

New fee income

Every claim you file is billable work that didn't exist before.

Client loyalty

Nothing holds onto a client like getting their money back.

Winning new clients

“We'll check whether you're leaving money on the table.” A concrete pitch.

Always current

When the law changes, the new version arrives.

Every update comes by email, with a short note on what changed. No server, no portal, no login.

The next step

See it on your own book of business.

A short message is all it takes. Then a conversation and a run across a few of your own clients — local, no commitment. If the result convinces you, we go from there.
