The problem

Spreadsheets won't survive an ICAEW review.

Most ACSP-registered firms are running identity verification today across four tools: a shared Excel workbook, an Outlook folder of client correspondence, a network drive of PDF documents, and a separate IDV provider's web console.

None of those tools generate a tamper-evident audit trail. None of them track which client owes which fee. None of them survive a supervisor inspection unscathed.

Endorser is a single workflow that replaces all four — built for the way UK accountancy firms actually work, not the way Silicon Valley assumes they do.

What you get

Automation, regulated verification, defensible evidence.

Three things every ACSP-registered firm has to do — run the verifications, prove the work to a supervisor, and keep a per-client record. Endorser does all three in one workflow, so you stop reconciling between tools that were never built for this regime.

i.
Automation

Verify at scale, automatically.

Bulk-send verification requests to hundreds of directors and PSCs in a single action. The recipient runs a regulated, biometric-grade check on their phone in under three minutes. 94% of clear cases auto-pass — no human review needed.

ii.
Regulated

Audit-grade evidence, on demand.

Per-client, per-individual, per-date-range. Every export is signed, timestamped, and hash-chained. The audit trail your AML supervisor wants — generated in one click, not stitched together from a spreadsheet and a network drive.

iii.
Operations

Track and report.

Per-client verification logs ready for billing, audit, or supervisor review. Every verification has a cost line. Every client has a running total. Export to your existing systems in one click — Xero, QuickBooks, your DMS, or a generic CSV.

The flow

From client list to evidence pack, in four steps.

Step 01

Import your clients.

Pull directors and PSCs directly from Companies House. Or upload a CSV. Endorser organises them by client, by deadline, by status.

Step 02

Send verification.

Select individuals, send a branded link by email. They complete the check on their phone in under three minutes.

Step 03

Review and approve.

Clear cases auto-pass. Edge cases land in your manual review queue. Every action is logged with a tamper-evident hash.

Step 04

Export the evidence.

One click generates a signed PDF and JSON evidence pack, ready for your AML supervisor or for your billing system.

The differentiator

Every action, chained and signed.

Endorser writes every material action — sign-in, verification result, evidence pack download — into a hash-chained log. Each row hashes the previous row. A regulator can verify the chain in front of you and prove that nothing has been altered.

The maths

What Endorser saves your firm.

Manual ACSP verification takes 30-40 minutes of staff time per individual, across spreadsheets, Outlook, a shared drive and a separate IDV provider. Endorser replaces all four with 2-5 minutes of supervised review. Pull the slider to see what that adds up to across your book.
