Earn with Vizibli: How Sustainability Consultants and Carbon Accountants Are Building More Profitable Practices
Carbon accounting is in demand. CSRD, SECR, UK SDR, and PPN 006/21 have created a generation of SME clients who need expert help — fast.
The problem isn't winning the work. It's delivering it profitably.
Most consultants are spending a disproportionate share of their time on data collection, calculation, and formatting — not on the advice that clients are actually paying for.
Vizibli changes that. It's a platform built to take the operational weight off carbon professionals so they can do more client work, with the same team, at better margins.
Here's how it works in practice.
1. Cut 90% of the admin out of Scope 1, 2 and 3 calculations
The most time-intensive part of carbon accounting isn't the expertise — it's the data wrangling. Chasing clients for utility bills. Re-formatting purchase ledger exports. Manually matching spend lines to emission factors. Cross-checking against GHG Protocol categories. For a typical SME client, this can absorb 10–15 hours per engagement before any analysis begins.
Vizibli connects directly to a client's existing accounting software — Xero, QuickBooks, Sage, Odoo, Joblogic — and automates the calculation of Scope 1, 2 and 3 emissions using approved GHG conversion factors.
The platform maps spend data to emission categories, applies the correct methodology, and produces a structured output that's ready for review — not ready to be built from scratch.
The result is a 90% reduction in the time consultants spend on data processing.
The calculations are transparent: every figure is traceable to a source, every factor is documented, every assumption is visible. That means your reports aren't just fast — they're audit-ready and compliant with GHG Protocol, SECR, and CSRD reporting standards.
Ltt Group, who work across construction and property services, were able to handle a significantly larger volume of carbon engagements without increasing the time their consultants spent on each one. The data pipeline that used to take days was down to hours. Their team spent that recovered time on analysis, client conversations, and recommendations — the work that differentiates a consultant from a spreadsheet.
2. Manage all your clients in one platform — and take on more without growing headcount
Most consultants manage carbon projects across a patchwork of spreadsheets, shared drives, and email threads — one per client, none of them consistent. It works until it doesn't.
Onboarding a new client means building everything again. Updating methodology means updating it everywhere. Reviewing last year's figures means hunting through folders.
Vizibli gives you a single platform to manage every client engagement. Each client has their own workspace, connected to their own data sources, with their own emissions history and reporting outputs. You can see across all of them at once — or drill into any one of them in minutes.
The commercial implication is direct: the capacity constraint in most sustainability consultancies isn't expertise, it's time. If processing one client's annual carbon data takes 15 hours and you have 20 clients, that's 300 hours a year on admin. Cut that by 90% and you've freed up 270 hours — the equivalent of adding a team member without the cost.
Disruption House are using this to scale their carbon offering without scaling their team. They are able to move from working with a handful of clients on carbon reporting to managing a much larger portfolio, confident that the platform would handle the calculation burden while their consultants handled the thinking.
For Sealand Projects, the ability to manage multiple ongoing client relationships from one place, with consistent methodology and comparable data across all of them, was what made the practice model viable at the size they wanted to operate.
3. Build recurring revenue with clients who stay
Advisory engagements are typically one-off or annual. A client commissions a carbon report, gets their GHG inventory, and that's the year done. The consultant starts from zero the following year. There's no compounding value, no retention dynamic, no reason for the client relationship to deepen over time.
Vizibli changes the economics. Because the platform holds a client's historical emissions data — connected live to their accounting systems — the value of the relationship increases the longer it runs. Year-on-year comparisons become automatic. Reduction tracking becomes meaningful. The consultant moves from producing a snapshot to managing a programme.
This creates the conditions for a subscription-based service model.
Consultants using Vizibli can package their service as a monthly or annual retainer: the platform handles data and calculations, the consultant handles strategy, reporting, and client advisory. The client gets a continuous relationship and improving data quality. The consultant gets predictable, recurring income.
The longer a client stays on the platform, the richer their data becomes — and the harder it is to replicate elsewhere.
That's not lock-in by design; it's lock-in through value. Clients who have two or three years of comparable, auditable emissions data tied to their live accounts aren't going to start again on a spreadsheet.
Ltt Group, Sealand Projects, and Disruption House all operate with exactly this model. Their consultants aren't starting from scratch each year.
They're building on a foundation that gets more valuable over time — and their client relationships reflect that.
Accuracy, compliance, and audit-readiness
For any consultant putting their name to a carbon report, the quality of the calculation methodology isn't optional. Clients face real regulatory scrutiny. Reports produced under SECR are submitted to Companies House. CSRD obligations carry legal weight. PPN 006/21 is tested at tender.
Vizibli uses approved conversion factors, applies GHG Protocol methodology across all three scopes, and maintains a full audit trail from raw spend data through to published figures. Every calculation is traceable. Every factor is documented. Every report can be interrogated, challenged, and verified.
That matters to your clients — and it matters to you.
Consultants who produce Vizibli-powered reports aren't asking clients to trust a spreadsheet. They're providing a documented, transparent methodology that stands up to scrutiny.
You stay in control of data quality, with a manual check before any report is visible to a client. And the data stands up to third party audit.
How to get started
Vizibli offers a partner programme for sustainability consultants and carbon accountants. You get access to the platform, onboarding support, and the commercial framework to offer it as a service to your clients.
