Why did you build a multi-tenant architecture rather than separate deployments per client?

Multi-tenant with role-based access means one codebase and one deployment serves every organisation, so updates to emission factors or reporting logic reach all tenants at once rather than needing 20 separate upgrades. It also keeps hosting cost per customer far lower, which matters when you are selling into mid-market sustainability teams with constrained budgets.

Emission factors and ESG reporting standards change constantly — how do you handle that?

We keep emission factors and reporting templates as configurable data rather than hardcoded logic, so a standards change is a data update rather than a redevelopment cycle. The platform pulls live carbon data through external APIs where available, and we scope an ongoing support arrangement for the reporting templates that shift most often, such as CSRD-aligned outputs.

Our auditors will question the numbers. Can the reported figures be traced back to source?

Yes — this was a core design requirement, since a reporting accuracy improvement is meaningless if an assurance provider cannot test it. Every calculated figure retains its input data, the factor applied and the timestamp, so a reported total can be decomposed back to the underlying entries during an audit.

Do you work fixed-price or time and materials for a platform like this?

For the initial discovery and a well-defined first release we generally work fixed-price so you have budget certainty for approval. Ongoing feature development after launch usually moves to a dedicated team or capped time-and-materials model, because product priorities shift once real customers are using the platform.

Project Type

SaaS Platform

The client is a European ClimateTech venture building carbon accounting software for mid-sized and large enterprises. Its customers operate across several EU member states, often with complex supply chains, multiple sites and reporting obligations that are tightening every year under frameworks such as the Corporate Sustainability Reporting Directive (CSRD) and the wider ESG disclosure agenda.

For these enterprises, sustainability reporting has moved from a voluntary marketing exercise to a board-level compliance requirement. The client recognised that sustainability teams needed more than spreadsheets: they needed a dependable SaaS product that could ingest emissions data continuously, calculate footprints consistently and produce audit-friendly reports. Technology was therefore the product itself, not a supporting function, and the platform had to be robust enough to win enterprise trust.

Confidential Client

This project was delivered under a Non-Disclosure Agreement. The client operates in the Sustainability sector (ClimateTech) and is based in Europe.

The Challenge

Prospective customers were tracking Scope emissions in sprawling Excel workbooks maintained by a handful of analysts. Data arrived late from facilities, conversion factors were applied inconsistently, and every reporting cycle involved weeks of manual reconciliation. As enterprise data volumes grew, these spreadsheets became fragile, slow and almost impossible to audit, leaving organisations exposed when regulators or investors asked how a number had been derived.

On the technical side, the client needed a platform that could serve many organisations from a single deployment without any risk of one tenant seeing another's data. It also had to pull live emissions data from external carbon APIs, handle bursts of calculation load around reporting deadlines, and generate structured ESG reports that sustainability managers could hand to auditors with confidence. Building this as a monolith would have limited how quickly new modules and integrations could be added.

Our Solution

PapaSiddhi designed and delivered a multi-tenant carbon accounting SaaS platform on a scalable microservices backend written in Node.js, with MongoDB as the primary data store. Tenant isolation and role-based access control were built into the data model from day one, so analysts, sustainability leads and administrators each see only what their role permits within their own organisation. Separate services handle data ingestion, emissions calculation, reporting and user management, allowing each to scale independently.

The React front end delivers AI-driven emission dashboards that refresh with real-time data pulled through Carbon API integrations, giving users an up-to-date picture of emissions by site, activity and category. An automated ESG compliance report generator assembles structured outputs designed to support CSRD-style disclosure, while export-ready analytics let teams share charts and tables with boards and auditors. The responsive interface works equally well on desktop and tablet for site managers in the field. Delivery followed an iterative, sprint-based approach, with the client reviewing working increments regularly. This allowed reporting templates and dashboard views to be refined against real customer feedback before general release.

Results & Outcomes

Enterprises moved from fragile spreadsheets to a single intelligent SaaS platform for emissions tracking across all their sites.
Reporting accuracy improved by 70% thanks to consistent, automated calculation logic and live carbon data feeds.
Manual data entry time fell by 85%, freeing sustainability analysts to focus on reduction strategy rather than data wrangling.
Automated ESG report generation gave customers compliance-ready outputs designed to support EU disclosure requirements such as CSRD.
The multi-tenant microservices architecture allowed the client to onboard new enterprise organisations from one deployment without re-engineering.
Real-time dashboards strengthened sustainability decision-making at board and operational level.

Enabled enterprises to track emissions more efficiently, improved reporting accuracy by 70%, and enhanced sustainability decision-making. Reduced manual data entry time by 85% and ensured full ESG compliance readiness.

Frequently Asked Questions

A carbon accounting platform at this scope — emissions tracking, analytics dashboards and compliance reporting — typically runs four to six months to a production-ready first release. We usually ship a working tracking and reporting core first so your sustainability team can start capturing real data while the analytics and multi-tenant layers are still being built.
