Bookkeeping Across the Hawaiian Islands

Balanced to the penny.

I am a QuickBooks bookkeeper for small businesses across Hawaii. Every account reconciled every month, so the numbers on your reports are ones you can do something with.

It costs nothing. We go through your QuickBooks together and I tell you what I see, whether you hire me or not.

What messy books cost

Profit looked 15,595.00 higher than it was.

Most books I open look clean from the outside. Underneath, they are built wrong, so your CPA has to go digging before they can file anything, and your reports do not tell you much.

In this example, that meant income tax on money the business never made. The free diagnostic is how I find it, and a bookkeeping cleanup is how I fix it.

How it works

The work, in four stages.

You can stop after any of them.

    Free Diagnostic

    We go through your books together. Within five business days I show you what I found and what I would do about it, on a call, in a short video, or in writing.

  2. II47

    Cleanup and Catch-Up

    If the books need fixing, you get a fixed price up front, based on what the diagnostic found. No hourly meter.

  3. III80

    Monthly Bookkeeping

    Monthly bookkeeping with every account reconciled to the penny. At year end your CPA gets books they don’t have to dig through.

    Profit and Cash Flow Advisory

    Once the books are right, the pieces start to fit. We use them to see where your profit comes from and to get ready for the slow months.

Hawaii GET

Hawaii has its own rules.

General Excise Tax is charged on gross income, so when income gets counted twice in the books, GET gets paid twice too. Nobody notices until someone goes looking. I look every month.

Kauai0.5% since 2019Oahu0.5% since 2007Maui0.5% since 2024Hawaii Island0.5% since 2020

4.5% on every island today, up to 4.712% passed on. If your books go back before 2024 on Maui, or before 2020 on Hawaii Island, the rate for those years was lower, and a catch-up has to use it.

My books were always super clean, and my CPA loved that there was nothing to fix at year-end.

About

Your Hawaii bookkeeper.

I’m Rodrigo Guerrero. I kept the books for my own businesses first, then spent two years training before I opened Crucible Ledger Co. This work fits what I believe in. It helps people, instead of just looking like it does. I am thorough, and I care whether your business makes it. Give it a few months and I start to feel less like your bookkeeper and more like a business partner.
