Built by a licensed audit firm

Developed by A4 Services Limited — a licensed audit and accounting practice. Not a tech startup guessing at audit.

02/ 04

100% of your general ledger reviewed

Our GL Anomaly Agent tests every single transaction — not a sample. Duplicate entries, unusual journals, late postings all flagged.

03/ 04

Your data stays yours

SOC 2 certified infrastructure, GDPR compliant. Your documents and financials are never shared or used to train models.

04/ 04

White-labelled to your firm

The client portal, all communications and documents are branded under your accountancy firm. Clients never see A4 Services.
