Sunday 11:12 PM

Your Sunday 11:12 PM. Fourth follow-up.

“Counsel, did you receive my bank details?” Fourth time this weekend. SAS Verdia is panicking about their late payment penalty.

Your clients send their documents to three different addresses, your intern swears they received everything, and your shared Drive keeps payslips on servers outside the EU. Article 226-13 of the French Penal Code, which you swore to uphold to the CSOEC, is looking the other way.

What if every document arrived in an encrypted vault on YOUR server, timestamped, traceable, and legally admissible?

Before / After

You bill 180 €/h. You lose 8 of them per week chasing after documents.

Four silent leaks occur when a client file is not tracked. Here is what they cost — and what Client Vault fixes, without heavy ERP systems or painful migrations.

Today · without a tracked vault

The daily routine that eats up your fees

  • 40 emails “do you have the 2024 financial statements?” / month — 8 hours of non-billable time weekly.
  • Payroll records outside the EU on Dropbox — article 226-13 risk.
  • No enforceable timestamped proof of DSN submission.
  • Shared drive for services billed at €180/h — poor firm image.

With Client Vault · tracked file

The firm that advises, rather than chases

  • Client engagement log — you see everything, you no longer need to send follow-ups.
  • AES-256 vault on YOUR server, in YOUR country.
  • Audit timestamped to the millisecond — upload, read, deposit.
  • URL cabinet-martineau.fr, your branding, your logo.

The tracked tax bundle

Your tax returns, tracked from mandate to filing.

Every file becomes a visual journey. The client knows the status of their tax return. The timestamped audit automatically creates the chain of evidence. You advise, the system follows.

D0

Engagement & KYC

The client accesses their portal. Engagement letter, certificate of incorporation (K-bis), bank details, certifications — everything is stored in an encrypted vault on your server, timestamped to the millisecond.

Due diligence

Tagged documents

The client uploads documents, payslips, and supporting evidence. You validate them or request missing files. Every action is logged. The assistant can track progress.

Auto · D+3 / D+7

Guided follow-ups

Missing a document for 3 days? Automatic email. 7 days? Notification in your dashboard. Never have a DSN rejected again due to a missing document.

Filing

Annual accounts + Archiving

Final accounts filed: a complete timestamped export of the file, evidentiary trail, and archiving in the vault. Stored on your own premises, with no recurring rental costs.

In practice: you configure your standard workflow once (TPE, VAT, Corporate Tax, Income Tax, associations). You then reuse it for your next 100 clients.

Why not Pennylane or Cegid?

Pennylane hosts your files in the cloud. Client Vault hosts them on your own infrastructure.

Standard professional ERP/Practice Management software

Pennylane · MyUnisoft · Cegid · Sage

  • ≈ €79/month/user (Pennylane Pro)
  • Hosted by the vendor
  • URL cabinet.pennylane.eu — not yours
  • No webhook or limited API

Client Vault · on your own site

Your firm’s vault

  • €299 / €599 — one-time fee, unlimited folders
  • Hosted on YOUR server (France/EU)
  • URL cabinet-bertrand.fr/clients/m-bertrand
  • Article 66-5 + webhook + REST API

Pennylane Pro at €79 × 5 users × 12 months = €4,740/year. Client Vault Pro: €599 one-time fee, unlimited users. ROI from the 2nd month.

67 firms equipped

Their corporate clients have stopped comparing them to neighboring firms.

At first, I was skeptical — we were already equipped with Pennylane and Cegid. Then I stopped receiving emails asking, “Do you have the financial statements?” My small business clients told me, “Finally, a firm that understands us.” That is what justified the migration, not the tech.

The ethical argument convinced my Regional Council of the Order. Payroll slips should never pass through Dropbox. With Client Vault, they are encrypted on our OVH France server. We hold the key. The software provider sees nothing. This is what professional secrecy requires.

Florence B.

Partner Chartered Accountant · Reims · firm with 4 staff members

Payroll involves intimate data — salaries, bank details, family status. I could no longer stand the idea of it going through a Pennylane platform over which I have no control. Here, I manage everything; it is on my server, under my name. My clients are grateful.

Sarah L.

Chartered Accountant · Aix-en-Provence

I migrated from Cegid Loop (€39/user/month × 7 = €3,276/year). Client Vault Pro: €599 one-time payment. Year 1 savings: €2,677. My clients see my website, not cegid.com.

PD

Pierre D.

Chartered Accountant · Bordeaux · 7-person firm

What convinced me was the delegation: each staff member has their own scope, each intern has theirs. I can grant access to my assistant without her seeing internal notes. On Dropbox, that was impossible. On Cegid, it was an €8,000/year module.

Émilie M.

Chartered Accountant · Nantes · 6-person firm

The timestamped audit log saved me in November. A client disputed receiving the provisional balance sheet. I generated the export in 30 seconds: sent at 2:22 PM, read at 2:47 PM, downloaded at 2:51 PM. The dispute ended right there. That is worth every fee.

FAQ for peers

Real questions from peers. Real answers.

Are my accounting documents truly confidential?

Yes. AES-256-CBC encryption at rest, HMAC-SHA256 integrity, hosted on YOUR WordPress server, not in a third-party cloud. The encryption key is stored locally on your end (600 permissions). No telemetry, no remote access, no back-doors — the developer sees NOTHING. Native GDPR (RGPD) compliant and adheres to professional accounting secrecy requirements.

I already use Cegid, Sage, or Pennylane. Why add Client Vault?

Cegid / Sage manage your entries and filings. Pennylane is your collaborative back-office. None are designed for day-to-day exchanges with the end client regarding financial statements, supporting documents, or certificates. Client Vault handles exactly this segment without touching your accounting ERP. Includes Webhook + REST API if you want to connect everything.

Will my executive clients actually use it?

The space is accessed via a simple secure link sent by email or SMS. No password to create, no app to install. Several firms report that their executive clients aged 50+ use the vault without assistance from the second time onwards.

Who sees our files on the Client Vault side?

No one. Files are AES-256 encrypted on your disk with a key stored on your premises. The publisher has no access, no telemetry, and no back-door. The source code is open (GPL) and verifiable. If you shut down your server, the publisher cannot recover anything — that is precisely the point.

Can I migrate from MyUnisoft or a shared drive?

Yes. An assisted import script retrieves existing files into the client vaults. The support team guides you through your first migrations, at no extra cost, as part of Pro support.

Where is my client data hosted?

On your own WordPress server, with the host of your choosing, in the country of your choice. If your host is in France (OVH, o2switch, Ikoula, Infomaniak), your files are in France. No data goes to Google, Amazon, or Microsoft. You remain in control of the location.

How can I delegate to my staff and interns?

The plugin registers the cv_manage_vault capability. You assign it via WordPress roles to your assistant, staff member, or intern. Everyone has their own scope (default: all folders; optional restrictions by client tag). Internal notes remain reserved for partners.

What if Client Vault disappears tomorrow?

Your data remains intact on your server. The source code is open (GPL). Your documents, exports, and audit logs are independent of the plugin and readable with any standard WordPress tool. There is no vendor lock-in risk, unlike with Pennylane or Cegid Cloud.
