AI for audit and assurance firms

Catch engagement risk as it moves, not after the fact

Cimba takes the manual, repetitive parts of the audit off your team's plate, sampling and tie-outs, chasing client documents, assembling workpapers, and surfaces what needs a partner's attention while the engagement is still ongoing. It runs your firm's methodology, not a generic one, and every step stays source-linked and auditable.

Awaiting conclusion from the engagement senior. Accept, amend, or reject is recorded against them.

The problem

Busy season is manual, not hard

Most audit hours do not go to the judgment work that needs a trained auditor. They go to the manual load underneath it, pulling samples, tying out numbers, chasing documents, formatting the file, and that load is what turns busy season into 70-hour weeks and wears down the people you most want to keep.

By hand

Samples and tie-outs by hand

Pulling samples and tying out numbers eats senior hours, and a sample still leaves most of the population untested.

Stalled

Chasing client documents

Requesting, tracking, and reconciling support from client ERPs, spreadsheets, and email stalls the whole engagement.

Too late

Risk surfaces too late

When everything is examined at the end, issues show up mid-review instead of early, when they are cheaper to fix.

Cimba takes that manual load off the plate and surfaces what needs a human look while the engagement is still moving, so your team spends its hours on risk and judgment.

Why audit firms choose Cimba

Your method, your evidence, your sign-off

Your methodology, not a generic one

Cimba ships with the standard procedures every audit engagement runs. Then it reads your audit manual, your prior-year files, your Alteryx flows, and your Excel tests, and publishes them as your firm's versioned library. Your method, running the same way on every engagement.

Manual work, off the plate

Sampling, tie-outs, document collection, and workpaper prep run automatically, so seniors and managers stop spending busy season on grunt work.

Catch risk as it moves

Instead of examining everything at the end, Cimba surfaces what needs a partner's attention while the engagement is still ongoing, with its Next Best Action, so issues surface early.

Full-population coverage where the data allows it

Every journal entry, every payroll gross-to-net calculation, every depreciation line, every instance of an automated control, tested rather than sampled. Where sampling is the right method, the method, parameters, and seed are recorded, so an inspector can reproduce the exact sample years later.

Auditable by design

Every step lands on a source-linked, append-only trail that records actor and timestamp. Click any figure and trace it to the GL line, transaction, or document behind it.

One consistent method, at scale

Approved workflows are versioned and deterministic, so every engagement runs the same trusted way, not a different spreadsheet each quarter. Standardize across the whole firm.

Governed and deployable your way

SOC 2 Type II, role-based access, per-engagement isolation, SaaS or inside your own VPC for sensitive client data.

Who it's for

Built for the way your firm actually runs

Large and global firms

Standardize testing across thousands of engagements on one versioned, auditable method, expand what is automated firm-wide, and deploy inside your own VPC at scale.

Growing and mid-market firms

The standard procedures come ready to run, and your own methodology goes in on top, so you deliver Big-Four-caliber audits at a fraction of the tech spend and win work above your weight.

Internal audit teams

Move from periodic reviews to continuous assurance. Cimba monitors controls and transactions year-round and routes exceptions to the owner.

And the companies that run on Cimba come to their audit with a complete, source-linked trail already in place.

How it works

Connect, test, flag, conclude, document

Five steps, and a named person owns the conclusion at every one of them.

1

Connect

Point Cimba at the client ledgers, ERPs, and files in scope.

2

Test

It examines the full population continuously against your firm's procedures and risk criteria.

3

Flag

What needs a human look surfaces as the engagement moves, ranked by risk, with the cause traced and support linked.

4

Conclude

A named person accepts, amends, or rejects each flagged item, and that decision is recorded with them against it.

5

Document

Every step lands on an append-only trail and drops into the workpaper, ready for review.

The routines

The testing your team repeats every engagement, run the same way every time

Configured once against your firm's methodology, then run on every engagement. Each routine is auditable the same way, and each one records how it reached its conclusion.

Journal entry testing

Full population. Completeness is proved to the trial balance first, then entries are scored against your firm's own risk criteria.

Revenue

MUS sampling, with cut-off tested on both sides of year end.

Receivables

Ageing re-performed from invoice dates rather than accepted from the client's report, and subsequent receipts matched to specific invoices.

Cash

Confirmations issued and received by the firm, never routed through the client.

Payroll

Gross-to-net recomputed for the full population and tied to the filings.

Expenditure

Search for unrecorded liabilities, with coverage stated.

Fixed assets

Depreciation recalculated over the full register.

Inventory

Count selections generated in advance. A person performs the observation.

Analytics

The expectation is committed before the recorded figure is shown.

Controls

Attribute sampling, with the upper deviation limit compared to tolerable rather than the observed rate.

The comparison

Not a tool bolted on. A way to run the work

Not a data-prep tool, not a chatbot, not a scripting environment. An auditable way to run the work.

If it cannot run your methodology, prove its coverage, and show how it reached a conclusion, it is a tool, not a way to run the audit.

Trust

Every conclusion traceable to the line behind it

An audit team uses Cimba to test 100% of journal entries and auto-assemble the support, cutting sample prep and document chasing and pulling exceptions forward weeks, so reviewers get time back.

Frequently asked questions

No. It does the manual and population-level work, the sampling, tie-outs, evidence, and workpaper prep. A named person accepts, amends, or rejects every flagged item, and the conclusions and sign-off stay with your team.

Yours. Cimba ships with the standard procedures every engagement runs, then reads your audit manual, your prior-year files, your Alteryx flows, and your Excel tests and publishes them as your firm's versioned library. Your methodology stays your methodology.

Role-based access, per-engagement isolation, SOC 2 Type II, and SaaS or your own VPC. If the client uses Cimba too, independence is not affected: Cimba is a tool the firm operates, not a service provided to the client, and the two sides are separate tenants with per-engagement isolation.

It reads from major ERPs, ledgers, warehouses, and Excel, with no rip-and-replace.

Yes. A source-linked, append-only trail records actor and timestamp on every query, result, and action, including who accepted or amended each flagged item.

Those are powerful, but you build and maintain the workflows and they stop at the data. Cimba runs your firm's methodology as a versioned library, works across client stacks, flags risk while the engagement is still moving, and records how it reached every conclusion.

Yes. It monitors controls and transactions year-round and routes exceptions to the owner.
