For ACSP-registered accountancy firms

The endorser's workflow.

You're the one putting your firm's name to every Companies House identity verification. Endorser is the platform that makes that workflow audit-grade — so you can run the verifications, generate the evidence pack your AML supervisor expects, and bill your clients without the spreadsheets.

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.

i.
Audit risk grows with every verification logged outside a system of record.
ii.
Firms underestimate verification volume by 30-50%, missing PSCs and LLP members.
iii.
£35-per-verification revenue is impossible to track in a shared spreadsheet.
iv.
November 2026 is closer than the average partner has scheduled for.
The product

One workflow. Three jobs.

Endorser handles the three things every ACSP-registered firm has to do, and does them in one place — so you stop reconciling between tools that were never built for this regime.

i.

Verify identities at scale.

Send verification requests in bulk. Individuals complete the check on their phone via an integrated IDV provider. Status returns to your dashboard in seconds. Manual review queue for the edge cases.

ii.

Generate evidence packs.

Per-client, per-individual, per-date-range. Every export is signed, timestamped, and tamper-evident. The audit trail your AML supervisor wants — without the spreadsheet hygiene.

iii.

Track and bill the fee.

Every verification has a cost line. Every client has a running total. Monthly export to your existing billing system, or invoice direct from Endorser. Margin protection, automatic.

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.
