Persefoni is a well-known carbon accounting platform often marketed to enterprise finance teams. Many mid-market and lean enterprise teams evaluate it and then ask whether a more transparent, self-serve alternative exists. OffGridFlow is that alternative.

What OffGridFlow does differently

  • Published methodology: every factor source, calculation method, and standards alignment is documented at /methodology — version v2026.1.0 right now.
  • Public pricing: $6,500, $10,800, $15,000, and custom tiers listed on the pricing page. No per-employee add-ons.
  • Sample evidence pack: downloadable redacted audit packet at /evidence so prospects see the output quality before they sign.
  • Self-serve path: CSV upload to first report in under two hours, no mandatory consultant engagement.
  • Honest operations: live status page, published architecture, no fabricated testimonials or unverified certifications.

When to choose Persefoni instead

If you need a large enterprise rollout with dedicated implementation consulting, an extensive supplier-engagement module, and integration with a CSM team — Persefoni is the established choice. OffGridFlow is optimized for mid-market and lean enterprise teams that want defensibility without the consulting premium.

Frequently Asked Questions

Why consider OffGridFlow instead of Persefoni?

OffGridFlow publishes its methodology, factor sources, and sample audit packet before you sign a contract. Pricing starts at $6,500/year and is listed publicly. Self-serve CSV upload reaches a draft report in under two hours — no consultant engagement required.

Is OffGridFlow as comprehensive as Persefoni?

OffGridFlow covers the full Scope 1/2/3 calculation surface, all five major frameworks (CSRD, SEC, SB 253, CBAM, IFRS S2), and cloud connectors (AWS, Azure, GCP, SAP). Persefoni has a longer enterprise feature list; OffGridFlow has a narrower, more defensible core with the essentials in place.

How does support compare?
