About FairLedger

The fair-value evidencing platform for UK payment and e-money firms.

FairLedger turns your own transactional and pricing data into defensible, board-ready Consumer Duty evidence — reproducible on demand, without a consulting engagement.

What it is

FairLedger is a multi-tenant SaaS platform that auto-evidences the two quantitative Consumer Duty outcomes — Price & Value and Products & Services — for UK payment and e-money firms.

You upload your orders and published price lists. FairLedger validates every row, computes reproducible fair-value metrics, flags outliers against your own pricing, and assembles a board pack your compliance committee can defend line-by-line.

What used to be a quarterly consulting deliverable becomes a repeatable operational output — versioned, auditable, and produced from source data your firm already owns.

Why it matters

Consumer Duty made the evidence bar quantitative. Most firms are still answering it qualitatively.

The FCA now tests whether firms can produce numerical fair-value evidence on demand. Boards need it. Auditors ask for it. Regulators expect it in the format FairLedger produces.

Quantitative by default

Fair-Price Gap, price dispersion, margin distribution and SKU-level outliers — computed from your data, not estimated.

Defensible by design

Every metric ties back to the source batch, the row range, the price list version and the run timestamp. Nothing is a black box.

Board-ready output

A one-click PDF board pack with headline metrics, outlier tables, methodology appendix and sign-off block.

How it works

From CSV to board pack in four steps.

01

Ingest

Drop in orders and price-list CSVs. Row-by-row Zod validation preserves invalid rows for review.

02

Analyse

Reproducible metric snapshots: revenue, margin, dispersion, Fair-Price Gap, top-SKU breakdown.

03

Evidence

A tenant-scoped Evidence view with immutable snapshots and full audit trail across every run.

04

Publish

Export the branded board pack PDF, complete with methodology appendix and version stamp.

Platform

Built like a regulated system, not a spreadsheet macro.

Multi-tenant workspaces

Owner / admin / member / viewer roles per workspace, with tenant-scoped row-level security on every table.

Private by construction

Storage is folder-isolated per tenant. Row-Level Security enforced in the database. No cross-tenant reads, ever.

Immutable snapshots

Every analysis run writes a metric snapshot tied to the input batch — reproducible months later for audit.

Audit trail

Every ingest, delete, member change and evidence export is logged to a tamper-evident audit log.

Board pack PDF

Branded React-PDF output with headline metrics, Fair-Price Gap tables, top SKUs and a methodology appendix.

Operational metrics

Revenue, margin, price dispersion, monthly time series and top-10 SKU breakdown — refreshed on every batch.

Who it's for

Purpose-built for the UK payments mid-market.

Payment institutions

Authorised PIs producing fair-value evidence across merchant and consumer product lines.

E-money institutions

EMIs evidencing pricing outcomes across cards, wallets and cross-border rails.

BaaS platforms

Programme managers evidencing outcomes for downstream branded programmes.

Compliance teams

Second-line functions who need a defensible, repeatable evidencing operating model.

Principles

The commitments the product is built on.

Reproducible

Any metric shown in the app can be re-derived from the exact batch and price list that produced it.

Defensible

The methodology is documented, versioned and printed alongside every board pack — nothing is hidden.

Operationally lean

Built to be run by compliance and finance teams — not to require a data science function.
