PPCS works exclusively with firms that handle sensitive financial and personal data — where trust, confidentiality and defensible governance aren’t optional extras.
From sole practitioners to 100+ partner firms across the UK.
Practical governance that fits smaller teams and client-first workflows.
Protect employee data, HMRC credentials and the workflows that move salaries.
Independent assurance and standards-aligned controls your regulators recognise.
Cyber Security and AI Governance are becoming the two questions every accountant is asked — by clients, insurers, and regulators. PPCS covers both, delivered as a single, joined-up programme.
Protect client data, meet insurer expectations, and demonstrate a defensible security posture.
Show clients, insurers and regulators that your firm’s use of AI is safe, documented and defensible.
Good governance should be strong enough to hold up under audit, but practical enough that your team actually adopts it. That balance sits at the centre of everything we do.
Delivered around how firms actually operate — client deadlines, busy season, small teams. No generic templates, no unnecessary overhead.
Controls sized to your firm, not to a Big-4 audit team. The right level of documentation for your maturity — no more, no less.
Aligned to recognised standards (Cyber Essentials, ISO 27001, AIGAS, ISO 42001) so evidence holds up with clients, insurers and regulators.
Every firm is at a different point. These are the two ladders we help you climb — one step at a time, with real work delivered at each stage.
AIGAS is the first practical AI governance framework built specifically for accounting, bookkeeping and payroll firms — the sector-specific bridge between everyday AI use and ISO 42001. PPCS is a founding delivery partner.
Delivered by practitioners, tailored to accounting workflows, and short enough to fit around fee-earning work.
Phishing, credential hygiene, safe file handling — practical training for every member of the team.
What your staff need to know before touching ChatGPT, Copilot or embedded AI in Xero & Sage.
Board-level training on AI risk, oversight, sign-off, and evidence — aligned to AIGAS and ISO 42001.
There are plenty of generalist cyber consultants and plenty of AI hype merchants. We are neither.
Every framework, template and control is written for accounting, bookkeeping, payroll and audit workflows.
Cyber Essentials, ISO 27001, AIGAS and ISO 42001 — translated into work your team can actually do.
Governance that helps you win larger clients, satisfy insurers, and reduce breach risk — not just paperwork.
25+ years in accounting software and technology. You deal with practitioners, not junior consultants.
“Accounting firms don’t need more theory. They need a framework strong enough to stand up to scrutiny, and practical enough that their team will actually use it. That’s what we build.”Sal Nasser Founder of PPCS • Chair of the AIGAS Standard
