Margin Books

One person, in Adelaide, who answers the phone.

Books done by someone who has to do their own.

Margin Books is me, Joshua Dsa. Business owner, accounting graduate, and someone who learned bookkeeping the hard way before deciding to do it properly for other people.

Halo Glo is a body contouring and aesthetic clinic in Mawson Lakes. Two staff, a few treatment rooms, a lot of receipts.

Where this came from

Running Halo Glo

When I opened the clinic I let receipts pile up, reconciled in a panic before BAS and paid an accountant to untangle it. Most of what I was paying for was data entry at accountant rates. So I learned to do it properly: bank rules, receipt capture, weekly reconciliation, a one page report I'd actually read. The books went from a quarterly crisis to a Tuesday morning job.

External audit at KPMG

Working in KPMG Adelaide's audit team showed me the other side: what auditors and accountants look for in a set of books, where small businesses go wrong, and how much easier everything is when the records are right the first time. That standard is what I bring to a salon's Xero file.

The Adelaide University Tax Clinic

Part of the National Tax Clinic program, where students help people who can't afford a tax agent, supervised by qualified tax professionals. Sole traders with ATO letters, businesses behind on BAS, people negotiating payment plans. Nearly every problem started the same way: nobody had kept the books.

Margin Books exists to stop that before it starts. Fixed prices, written down, for the salons, cleaners, cafés and trades around me.

If a client's accountant ever says "who did these books?", the answer should be "good question, they're tidy".

How I work

Weekly, not quarterly

Small errors are cheap to fix in the week they happen.

Your file, your software

Xero and Hubdoc are in your name. You keep everything.

With your accountant

They keep doing your tax, from a reconciled file.

Questions in batches

One list a week, not a message per receipt.

Read only, always

I see your feeds through Xero. I never hold your banking login.

Plain English

If a line needs an accounting degree to read, it's rewritten.
