Where most teams get stuck
Where most teams get stuck
Most teams can calculate carbon numbers. The difficulty starts when those numbers need to be trusted, explained, or reviewed later.
Aligning across teams with different assumptions
Rebuilding calculations from scattered spreadsheets
Problem
The problem is rarely effort. It is the workflow.
Carbon reporting often starts in spreadsheets, then spreads across copied formulas, email threads, and last-minute checks. Teams lose time reconciling versions, rechecking calculations, and explaining numbers that are hard to trace back to source activity. This is where spreadsheet-based workflows start to break down, even when the numbers themselves are technically correct.
Manual checking keeps returning
Multiple files, copied formulas, and side notes create recurring rework before each review or reporting deadline.
Internal review breaks across teams
Finance, sustainability, and operations often work from partial context, so the same number gets challenged in different places.
Delays appear when reporting matters most
When the source activity and calculation basis are hard to explain, reporting slows down right when teams need a defensible answer.
Solution
A structured workflow from activity data to reporting
Teams record and organize activity data in one place. Karvoix applies factor-backed calculations, keeps the calculation context readable during review, and helps teams generate structured reporting outputs from the same underlying workflow.
Built for ongoing carbon accounting work, not one-off reporting exercises
Instead of rebuilding logic each cycle, teams work from a system designed for calculation, review, reporting, and traceability. That makes the process easier to revisit, explain, and use across recurring reporting periods.
Input
Recorded activity data
Calculation
Factor-backed carbon logic
Output
Review-ready reporting
Capture and organize activity data
Give the reporting process a more stable starting point than disconnected sheets and copied summaries.
Keep calculations readable during review
Teams can inspect the basis of the result instead of treating the number as something they simply receive.
Generate reporting from the same workflow
The same structured process supports internal review, snapshots, and reporting outputs without separate reconstruction.
Carbon Operations API
Connect the CFO API baseline to real operating systems
Karvoix is not just a reporting dashboard. It is a backend-backed Carbon Operations API baseline that teams can already connect to ERP, logistics, manufacturing, or internal reporting workflows through a controlled phase-1 integration path.
Start from activity data your systems already produce
Send activity through the calculate API or the CSV import baseline using the same guarded surface the backend actually supports today.
Karvoix calculates and stores carbon truth in the backend
Results are calculated and persisted in one system of record rather than derived temporarily in client-side logic.
Read activity back and inspect ledger trace later
Teams can read submitted activity back and inspect historical trace through the ledger when numbers need to be explained later.

Quickstart, API reference, and developer surfaces are shared during controlled pilot onboarding.
Real API baseline
A narrow but usable public integration surface already exists
The current phase-1 baseline includes activity submission, facility support, activity readback, ledger trace, CSV validate/import baseline, and credential surfaces for API keys, service accounts, and webhooks.
Included in this baseline
- activity submission and calculate API
- facility support
- activity readback
- ledger trace
- CSV validate/import baseline
- API key / service account / webhook surfaces
Not included in this phase-1 scope
- full dashboard API
- analysis API
- monitoring API
- factor governance API
- async bulk ingestion
- full developer platform
This is the current phase-1 public integration baseline for pilot and controlled rollout, not a full public platform.
Quickstart, API reference, and developer surfaces are shared during controlled pilot onboarding.
Differentiation
More usable than spreadsheets, more durable than ad hoc reporting
Karvoix is not just a place to store totals. It helps teams review how numbers were formed. Activity data, factor-backed calculation context, and reporting outputs stay closer together, so internal reviewers are not left chasing logic across files.
More reliable than spreadsheets
Teams work from a connected workflow instead of rebuilding carbon logic across files, tabs, and copied calculations.
More durable than consultant-only handoffs
Internal teams keep a system they can revisit between reporting cycles instead of relying on one-off output packages.
More reviewable than lighter tools
Karvoix keeps calculation context closer to the result, so the workflow supports real review rather than summary viewing alone.

How it works
A clearer path from source activity to reported numbers
Each step keeps the process closer to the underlying activity data and easier to review than a spreadsheet-led workflow.
01
Input activity data
Teams record or import the activity data behind the numbers, creating a cleaner starting point than disconnected sheets.
02
Apply factor-backed calculations
Karvoix applies carbon calculations using factor-backed logic where appropriate, making the basis easier to review than formulas and comments.
03
Review and trace results
Users inspect totals, contributors, and movements with the supporting context still visible, reducing back-and-forth during internal review.
04
Generate structured reports
Reports and snapshots come from the same structured workflow, making reporting more repeatable and less dependent on manual reconstruction.

Product proof
Real product surfaces for real review work
The screenshots below are meant to show workflow evidence: what teams see, what they can review, and how Karvoix supports ongoing reporting work rather than decorative dashboards.
Dashboard preview
A dashboard that gives internal review a clearer starting point
This is where teams see headline totals, recent movement, and the first signals that need explanation without opening a maze of spreadsheets first.
Analysis preview
Analysis surfaces that help explain what changed
The analysis view shows how contributors, categories, and period movement can be inspected in one place when teams need to defend or discuss the number.
Reports preview
Reporting views built for recurring review, not one-off exports
These surfaces show how summaries and snapshots can stay tied to recorded activity and calculation context before they are shared more broadly.
