One login.
Every client.

Run CSRD, EU Taxonomy and double materiality for 20-200 client organisations from a single partner workspace. Each client fully isolated. Your team, your roles, your review trail.

How it works

01

Sign up as a firm

At onboarding, choose “I manage ESG/CSRD for multiple client companies.” That flags your workspace as a partner account — no separate product, same ESGMaster.

02

Add your clients

Create a client organisation in a few clicks — name, industry, country, size. Each one gets the full platform: emissions engine, ESRS wizard, AI gap analysis, reports.

03

Switch and work

One switcher in the sidebar moves you between clients instantly. Every client's data is isolated — nothing bleeds across organisations, and every action is attributed in the audit trail.

Built for the channel

Multi-client workspace

Manage as many client organisations as you take on, from one login. No juggling separate accounts or spreadsheets per client.

Full data isolation

Each client organisation is a fully separate tenant. Client A can never see Client B's emissions data, reports, or audit trail — enforced at the application layer on every request.

Team roles for your firm

Invite associates and reviewers to your firm's workspace with owner / admin / editor / viewer roles. Manage who can touch which client's data.

AI-powered for every client

The same AI gap analysis, ESRS drafting and report generation your own clients would pay €9,000/yr for — available across your whole book of business.

Assurance-ready audit trail

Every calculation and edit is logged per client, timestamped and attributable — the trail your engagement sign-off and any third-party assurance work will need.

White-label & SSO

On the roadmap for firms managing larger client rosters — talk to us if this is a blocker for a specific engagement.

The arithmetic

One closed firm managing 20+ client organisations is worth more than 20 individual self-serve signups — and your clients get a platform, not a spreadsheet.

Questions firms ask us

Is this a separate product from the main ESGMaster platform?

No — same platform, same engine. Your firm gets a “partner” workspace type with a client switcher layered on top. Nothing about the underlying CSRD/VSME product changes.

How is billing structured?

Custom — typically a per-client seat pack or a percentage of client ACV, negotiated with your firm rather than a fixed self-serve price. Email us and we'll work out what fits your client roster.

Can a client log into their own organisation directly?

Not in the current version — client organisations you create are managed through your firm's workspace only. If direct client login becomes a requirement for your engagement, tell us — it's on the roadmap.

What happens to a client's data if we stop managing them?

Their organisation and all its data stays intact and exportable — removing a client from your workspace doesn't delete anything.

Do you support VSME (the simplified standard for SMEs)?

The VSME module is on our near-term roadmap alongside the full CSRD suite — useful if some of your clients are exempted SMEs responding to bank or customer ESG questionnaires rather than filing full CSRD.

Custom pricing — per-client seat or firm contract
