In brief: if you are a WordPress agency already serving professional firms — lawyers, notaries, chartered accountants — and you see your clients managing their documents via Drive, WhatsApp, or WeTransfer, you are in an ideal position to offer them a sovereign vault. Here is the two-minute pitch, the technical argument, the business model, and how to handle the most frequent objections.
You are a WordPress agency with a small team. You have been managing a law firm’s website for three years. You can see that its partners send legal documents via email, that clients upload their files to an improvised shared Drive, and that no one in the firm knows where the latest version of a file is. You have already told yourself this is a risk for them, but you do not know how to approach it commercially. This article provides the method.

Why your agency is in an ideal position
Three factors give you an advantage that no American SaaS provider can copy. First factor: the existing relationship. You are already the firm’s technical contact. You have their trust. When you suggest a change, your credibility is higher than that of a salesperson making a cold call.
Second factor: your technical legitimacy on WordPress. The firm will not have the expertise to evaluate a business plugin on its own, choose a host, harden an installation, integrate an SSL certificate, or configure a child theme. That is exactly your job. Where a turnkey SaaS reduces your role to zero, a sovereign plugin makes you indispensable.
Third factor: your business model. You are already billing your client for a maintenance subscription or a development package. Adding a business-oriented plugin like Client Vault means expanding the scope of the existing contract. You are not creating a new business relationship; you are extending the one that is already working.
The two-minute pitch
Here is a script that you can adapt and use as is during your next regular meeting with your client firm. “I noticed, while managing your site this year, that your clients are sending their documents via email and WhatsApp. As you know, Article 66-5 and the GDPR impose a certain level of discipline on these channels. Most of the firms I see are not truly compliant, but the risk has not materialized as long as no client has asked questions. That is starting to change.”
There is a simple path that does not require changing your management software or disrupting your daily routine: a digital safe installed on your WordPress, hosted in France, where your clients deposit their documents in a private space and where every action is tracked. For you, it means zero follow-ups, and compliance becomes a structural process rather than a constant battle. For your clients, it is more reassuring and more professional.
On the technical side, I take care of everything: hosting, installation, configuration, branding, training your staff, and annual support. You give me one day to configure it, and you have it in production. The entry cost is limited, and everything remains on your WordPress, so you retain control if you want to change anything tomorrow. Would you like to look at a demo together next week?”
Technical arguments for a law firm
When a firm asks you why not use Septeo, Closd, or Jarvis Legal, here are the angles to take. Septeo and Secib are tailored for established firms with volumes that justify their complexity and pricing. For a firm with fewer than ten lawyers, the cost-benefit ratio is rarely aligned. Closd is excellent for M&A transactions, but irrelevant for the day-to-day operations of a general practice firm. Jarvis Legal lost its independence with the 2024 LexisNexis acquisition — its roadmap now follows the group’s agenda.
When a firm asks you why not use Clio, here is the angle. Clio is the global leader in legal SaaS, with an excellent product. However, it is a Canadian and American software publisher. All the firm’s data falls within the scope of the CLOUD Act. For a French firm, this requires a post-Schrems II impact assessment that no one keeps up to date. The administrative risk is latent.
When a firm asks you why not just use a well-organized Drive, here is the angle. A Drive provides neither strict segmentation by client, nor enforceable timestamping, nor access traceability, nor definitive deletion upon request. On paper, some of these elements can be configured, but in practice, no firm has the time to maintain them. And the RIN (Internal Regulations) is not interested in what is configurable; it is interested in what is tracked.
The economic model for agencies
For each Client Vault deployment at a professional firm, your margin is built on four lines. First line: initial setup. Count one to two agency days, billed at the standard daily rate. This is when you install the plugin, configure firm branding, integrate the SSL certificate, harden WordPress, and create initial user accounts.
Second line: training. Half a day to a full day for partners and their staff. This training is billed separately and is essential for the deployment to succeed. Without training, the firm will revert to its old channels within the week.
Third line: annual support and maintenance. Added to the existing contract or a dedicated one. Client Vault updates, WordPress updates, verified backups, user support. This line is recurring and constitutes the bulk of the margin over time.
Fourth line: evolutions. Sooner or later, the firm will want a specific integration with their billing software, or a new type of document request, or a customized workflow. These developments are billed as a fixed price or on a time-and-materials basis, relying on documented WordPress hooks.
For an agency that already has five to ten firms in its portfolio, Client Vault deployment on a few of them can represent a stable, predictable revenue stream that replicates as you gain new clients.

Handling the three most frequent objections
“We already use Septeo.” Honest answer: Septeo covers billing, practice management, and accounting—Client Vault complements this with a client portal and document collection, areas where Septeo is not best positioned. Both can coexist. Do not present yourself as a direct competitor; present yourself as a client-focused complement.
“We want a turnkey SaaS, not something we have to maintain.” Honest answer: the sovereign path requires you to trust your provider for maintenance—that is precisely their role. They handle updates, backups, and support. The firm has no more mental load than with a SaaS, yet retains data ownership and the choice of hosting provider.
“We don’t have a budget.” Honest answer: how many hours per week do you lose chasing clients for documents? For a four-person firm, those hours often represent several thousand euros per month in internal labor costs. The Client Vault deployment pays for itself in a few months on this gain alone. And the regulatory risk hanging over your current practice only has a price tag on the day it materializes—it is better not to wait.
Honest limitations
Client Vault is not for every agency. If your business is purely design-focused without deep WordPress expertise, deployment and support will quickly become a burden. You need at least one developer or technical lead who masters WordPress hooks, security, and hosting.
Likewise, some firms refuse the WordPress path on principle and prefer SaaS. It is not your role to convince them against their will. Focus on firms whose culture of technical autonomy and sovereignty is compatible with your proposal.
Let’s get to know each other
If you are a WordPress agency and this pitch resonates with your professional clients’ needs, let’s have a video call. Twenty to thirty minutes to understand your portfolio of firms, look at a typical deployment, and see if Client Vault aligns with your service offering. The discussion can also lead to cross-referencing work for agencies that want to position themselves as deployment partners.
Frequently asked questions
Can a WP agency resell Client Vault to its clients?
Yes. The business model is based on the value you provide in terms of integration: configuration, training, support, and updates. The plugin itself is licensed to the client’s firm, and the agency charges for the support and services provided.
How much should I charge for the Client Vault setup?
This varies according to your daily rate. Plan for one to two days of initial setup for a standard firm, plus half a day to a full day for training. At standard French WP agency rates, this represents a consistent budget that is easy to justify to the firm.
Do you need to be certified to install Client Vault for a firm?
No formal certification required. A good command of WordPress, hooks, security, and French hosting is sufficient. For paramedical professionals requiring HDS hosting, your agency must be familiar with the specifics of OVHcloud Healthcare or Outscale.
How should Client Vault be positioned against Septeo?
Not as a direct competitor. Septeo covers firm billing and accounting; Client Vault covers the client portal and document collection. Both can coexist depending on the firm’s needs.
Which WP agency clients are the most profitable for Client Vault?
Professional firms with four to twenty employees: lawyers, notaries, chartered accountants, brokers, Qualiopi trainers, liberal paramedical professionals, and real estate agencies. These structures are large enough to make a deployment profitable and have the regulatory sensitivity that justifies the investment.
Is there a partner program?
A support framework for WordPress agencies is gradually being structured. Let’s discuss this during a demo to review the terms based on your profile and the volume of firms you plan to equip.
