I had no idea my top seller was barely breaking even after ads and returns. Mark has fixed all of this. That one insight basically paid for the whole service. Wish I'd done this a year ago! A++++

I’ve worked with RMK Group Consulting for a few months now and couldn’t be happier. They helped me clean up years of messy records and now handle everything monthly. If you’re a small business owner, you need them in your corner! Mark has made bookkeeping so easy. He helped set up QuickBooks, categorized everything, and sends me reports I can actually understand. I’m spending more time running my business and less time stressing over finances.

We had been recording Amazon payouts into QuickBooks as a single line item for months. Mark broke everything out — fees, ad spend, refunds — and now we actually know what we're making. Our CPA stopped complaining too, which is a bonus

Thank you Mark!

Your Bookkeeper Doesn't Understand E‑Commerce — and It's Costing You

What "generic bookkeeping" actually looks like

✕Amazon payouts dumped as one big mysterious deposit — fees, refunds, and ad costs invisible
✕No idea which products are actually profitable after marketplace takes their cut
✕Books are months behind and tax season is approaching fast
✕Your CPA charges extra because they have to untangle what should already be clean
✕Sales tax nexus obligations? Completely ignored
Every month with messy books is a month you're making decisions in the dark. You can't confidently reorder inventory, you can't tell if your ad spend is paying off, and you dread every conversation with your CPA.

The problem isn't you — it's that your bookkeeping wasn't built for e‑commerce.
