Relay

Audit automation, built by auditors

Half your audit can be automated by AI.Relay does that half.

Relay does the keying, the tying out, the rebuild every time the figures change — so your time goes to the numbers that don't look right.

Latest from the blogCloser to the EvidenceAn auditor's real work is the ten seconds it takes to sign. AI can build the workbook — but only if every figure stays traceable, so scepticism has evidence to land on, not just a conclusion to trust.

Under the hood

What Relay is built on.

Relay is built across seven layers, from the AI models up to the audit interface, so the work it produces is accurate, reviewable, and safe to use on a real engagement.

01

Large Language Models

Relay is model-agnostic, selecting the best model for each task. The better the models get, the more ambitious the experiences we can build.

02

Agentic Harness

The agentic harness is the orchestration engine turning general-purpose LLMs into audit-specific agents. LLMs are necessary but insufficient for audit work.

03

Data and Integrations

Native integrations with your audit methodology, engagement software, email, Excel, and more. The aOS operates as part of the firm's ecosystem, not alongside it.

04

Context and Knowledge

The agent is constantly evolving, learning from current-year and prior-year workbooks in real time while referencing client emails and submitted source documents.

05

Audit Capabilities

Audit-specific domain knowledge with reference to local and international standards such as IFRS and GAAP, ISA methodology, and Office and Google suite workflows.

06

Product and Interface

Purpose-built surfaces for every audit workflow: drafting, research, preparation, client delivery, and workpaper finalisation. Built from the ground up for audit.

07

Security and Governance

The foundation that makes the aOS enterprise-ready: ethical walls, cross-matter isolation, audit trails, and secure data storage according to your organisation's requirements.

How it works

Audit execution, run by agents — reviewed by you.

You run the audit. Relay's agents do the execution — planning prep, evidence requests, population testing, exception analysis, and reviewer-ready write-ups — and bring every step back to you to sign off.

Audit Bench

Benchmarking audit judgement, not chat.

Audit Bench is our AI evaluation framework for real-world audit work. It uses lifelike audit scenarios to benchmark how different models plan, inspect evidence, apply methodology, and produce reviewer-ready output.

Designed with chartered accountants

Cases are shaped with practising audit judgement so models are tested against how audit work actually breaks.

FAQ

Questions auditors ask.

What makes Relay different from other AI audit tools?

Relay works across the whole engagement rather than one workpaper at a time. When you're working in receivables, it already holds the bank statements, the client's emails about term sheets, the invoices and the open testing workbook to cross-reference. When the client's figures change, everything affected updates.

What happens to our client's data?

Relay keeps no client files. Source documents and drafted workbooks are never retained. What we do keep is an encrypted map of the engagement — file metadata, content summaries and how the documents relate to each other, plus limited account and security records. We keep it for as long as you're using Relay, so you don't have to re-upload each period, and we delete it when you stop using Relay or ask us to. Some AI processing happens outside South Africa; this is covered by POPIA's cross-border rules and set out in full in our privacy policy.

Is our data used to train AI models?

No, never. Every AI provider Relay uses is contractually bound to zero data retention: prompts and outputs are never stored after processing and are never used to train or improve any model.

Does it integrate with CaseWare?

Relay reads the files CaseWare produces on your computer — templates and workpapers included — so the two work together. Use both for as long as you like. Relay is built to replace legacy engagement software with something simpler and more powerful, but you can decide how it fits into your workflow.

Can it use our firm's templates and methodology?

Yes. Relay drafts workpapers from your own templates and methodology — your formatting, your referencing, your documentation standards — and applies them consistently across every engagement.

What does this mean for our audit team?

Audits are done in a fraction of the time, and quality goes up. Relay does the manual work; your team reviews, judges and signs.

What does it cost?

Each engagement gets its own price, based on its size. The price is set before the audit starts and doesn't change with how it runs.
