The work that never shows up on an invoice

You didn't build a firm to run a collections desk.

Four kinds of repetitive operational work quietly eat your team's week. None of it requires an accountant — but all of it lands on one.

300+

chase emails a season

Your team spends the first two weeks of every engagement asking the same clients for the same five documents.

Day 12

and still no clear picture

Halfway through the month and nobody can say which closes are actually done without pinging three people.

2–3 wks

to onboard one client

A signed client waits while intake, portal access, and document requests crawl through manual handoffs.

3,000+

transactions, 12 that matter

Reviewers scroll past thousands of clean transactions to catch the handful of real exceptions.

How we work

From one workflow to a system that runs itself.

We start narrow and prove it before we expand. No six-month implementation, no committee.

01

We map one process

On a 15-minute call we pick a single repetitive workflow you run today and trace exactly how it works — the steps, the tools, the handoffs, the points it breaks.

02

We design the automation

You get a plain-English plan: what gets automated, what stays human, what data is touched, and the numbers behind it. You approve it before anything is built.

03

We build on your stack

It connects to the tools you already run — QuickBooks, Xero, TaxDome, Gmail — through scoped, read-where-possible connections. No rip-and-replace, no new tool for clients.

04

We tune it with you

We pilot on a handful of clients, watch the real numbers, and tighten the system month over month. You see what it caught and what it saved.

Built on tools you already trust

No rip-and-replace. No new login for your clients.

The fastest way to lose an accounting firm's trust is to ask it to bet its workflow on a tool nobody's heard of. So we don't. Crest builds on top of the software you and your clients already use every day.

  • Built on your existing tools

    We connect to QuickBooks, Xero, TaxDome, Gmail and the rest of your stack. Nothing to migrate, nothing for clients to learn.

  • Not a black box

    Every system is documented in plain English: what it touches, what it does, and what stays human. You can see and explain how it works.

  • Read-only by default

    Connections are scoped to the minimum data needed and read-only wherever possible. Nothing writes to a client's books without your sign-off.

Run a tool that isn't here? If it has an API, we can almost certainly build on it.

The numbers

What this actually moves.

Concrete targets, not slogans. These are the outcomes we design each system to hit — and measure against once it's live.

11 hrs

Staff time saved per close

From eliminating manual document chasing on a ~40-client book.

3.5 days

Off the average month-end close

Mostly recovered by catching blocked steps on day 4, not day 18.

94%

Of transactions filtered before review

Only genuine reconciliation exceptions reach a human.

9 days

Faster client onboarding

Sequential manual handoffs collapsed into one automated flow.

Figures are modeled targets for a representative 2–20 staff firm, shown while we build our published case studies. We'll commit to your numbers, on your data, before you sign.

See it run on your firm's actual workflow.

A focused 15-minute call. We look at one repetitive process you run today and show you exactly how it gets automated — no slides, no obligation.

Built for US & Canadian firms with 2–20 staff.
