About
One person in Sydney, building websites and software for accounting firms.
What Mushin does
- Websites
- A new website for an accounting firm, with the copy written for you. It starts with a free written review of the site you have now.
- Automation and AI
- The mechanical work a firm still does by hand, done by code, with the exceptions handed to a person. Scoped per firm, one workflow at a time.
- Trust account audits
- The mechanical pass of a real estate agent trust account audit, handed back as working papers. Your firm stays the auditor.
- Vigil
- A review of offshore bookkeeping in Xero. It runs the checks a senior would do by hand before the BAS goes in, and shows only what it flagged. In a paid pilot.
The audit tool and Vigil are built the same way: code does the mechanical work, every figure keeps its source, and the exceptions go to a person. A website is a different kind of job, sold as one: a fixed price, a fixed scope, and a site your firm owns.
Who you are dealing with
I am Jesse Jenkins. Mushin is a one-person business in Sydney, NSW, with no team behind the name and no one else doing the work. When something needs explaining or fixing, the person you email is the person who built it, whether that is your website, the audit tool or Vigil.
On a trust audit, no other person sees the files you upload, and every service that touches them is named on how it works. Vigil reads your Xero and never writes to it: it edits nothing and lodges nothing. A website I build belongs to your firm: the domain and the code.
Why the audit tool exists
It was built for a Sydney firm that audits real estate agent trust accounts. The partner who runs those audits put the manual checking at roughly 4 hours per audit: twelve reconciliations to read, six figures a month to tie, a sample of receipts to draw and find on the bank statement. The tool now does that pass unattended in about 10 minutes and hands back three CSVs per trust account.
It was then made repeatable: a reproducible sample, a double-read on every figure, a review queue that names what a human needs to look at, and an output that declares its own scope limitation. That is the product on the trust audit page, and how it works is written to be checked line by line.
Where to start
The simplest first step is the free website review: one page on your firm's current site, with a score, 5 findings and the fixes, by email within one business day.
