For accounting & bookkeeping firms
One client's fraud becomes every client's doubt
Invoices and financial documents are your entire job — and your clients trust you to send them safely. Adlerwacht protects every document you send, without changing how your firm already works.
Built for firms whose job is other people's money
If your firm sends invoices, statements, or financial documents to clients by email — and especially if one or two people handle this for the whole practice — you're the exact profile this was built for. A single incident doesn't just cost one client money; it puts your firm's name on every other client's mind.
What it protects, specifically
Accounting and bookkeeping firms are targeted precisely because they handle money flows for many clients at once — a single compromised mailbox, yours or a client's, can expose invoice threads for every relationship running through it.
- Every client document — never sitting in an inbox in a form a hacked account could open, whether it's your mailbox or your client's.
- Delivery to the right client, and only that client — locked to a passkey, not just whoever's currently logged into the inbox.
- The document's contents — no altered invoice, no swapped account number, exactly what was sent is what arrives.
How this shows up in practice
An accountant sends a quarterly invoice to a long-standing client, from the same account they've used for years. Somewhere along the way — a reused password, a login on public WiFi — that account has already been quietly broken into. The attacker watches the thread, waits for the real invoice, and sends a follow-up: 'we've switched banks, here's the corrected account number.' It comes from the real thread, the real sender name, the real wording. The client pays it, in full, because nothing about it looked wrong.
Why accounting and bookkeeping firms choose Adlerwacht
Near-zero IT setup
No new software to learn, no changes to your existing email or practice-management tools — client documents are protected without adding a step to your day.
End-to-end protection, not a policy to remember
Clients unlock each document with a passkey, not a password — nothing to phish, nothing that degrades because someone forgot to double-check on the one invoice that mattered. New clients get an SMS-verified first check, confirmed by someone at your firm.
Priced for a practice, not a corporation
Plans start at €79 a month, and every new client relationship gets the same SMS-verified check as every other, included on every plan — nothing extra to remember to turn on for a first-time client.
