What it does

Purpose-built PSA categorisation and reporting

PSA preparation is often slow, manual and time-sensitive. Expense files arrive in different formats, descriptions are inconsistent, and the tax treatment still requires judgement. PSA.I standardises the workflow — from raw data to a defensible PSA result.

Flexible data ingestion

Upload spreadsheet-based data from finance, payroll, expense or general ledger sources. Column mapping supports client-specific file layouts.

AI classification with confidence

Each row receives a suggested PSA category and a confidence score, helping reviewers prioritise exceptions and edge cases first.

Reviewer-in-the-loop workflow

Categories can be confirmed, overridden or reassigned. The platform supports professional judgement rather than replacing it.

Data quality checks before review

Normalisation, duplicate detection and error handling clean the data up front, so reviewer time isn't wasted on avoidable noise.

HMRC-aligned reporting output

Once review is complete, PSA.I produces a grossed-up PSA calculation, including Class 1B NIC, ready for review and reporting.

Why PSA.I is different

Designed for the work, not around it

PSA.I is built specifically for PSA categorisation and reporting — not adapted from a general classifier or a general document tool.

Purpose-built for PSA

Designed around PSA workflow, categorisation and reporting, with dashboarding features to monitor progress.

Per-engagement isolation

Each PSA has its own data, category library and learning history. Confirmed patterns for one engagement do not bleed into another.

Defensible audit trail

Every upload, suggestion, override and final categorisation is recorded, supporting internal governance and HMRC enquiry readiness.

Human judgement built in

The platform is designed to accelerate review, not bypass it. Reviewers remain in control of every final categorisation.

Learns over time

Confirmed reviewer decisions improve future suggestions within each engagement, making the process more efficient as work progresses.

HMRC-aligned output

Produces a grossed-up PSA calculation by benefit type, including Class 1B NIC, ready for reporting.
