Yes I have recently taken over bookkeeping for a small company and see issues. The owner who previously did the books doesn't know what the issues are and I would like to clean them up.

By Lanell Flanagan on 3/18/2026

Very thorough information. I learned a lot and feel more comfortable about cleaning up my client's accounts. I'm sure that I will also refer back to this training again.

By Kochhar CPA on 9/22/2025

There's some good tips in here. Most of this covered what I already knew. I suppose i was hoping for the best way to spot and fix errors in QBO that have been handed off from a new client who has made a mess of the bank feeds and doubling up transactions for 2 years. The screen video was pretty laggy and jumpy making it hard to follow for anyone completely new to the procedures presented.

By Lisa Kirby-Martin on 7/2/2025

This was a nice methodical approach to cleanup. I really appreciated the extra videos for QBO, and I picked up a couple of tips I hadn't thought of before. Thank you!!

By Darlene Wallace on 5/9/2022

The instructor goes through a lot of detail and is very thorough. I would recommend this course to level up your skills. The videos are not long and they are interesting in the way in which presented.

By Cathy Francis on 2/28/2022

Very, very helpful. I've been a bookkeeper for years, but new to Quickbooks Online, and it is so very limited in what it allows a bookkeeper to do. I took on a client and was lost about how to proceed, where to find things, how to clean up years of mistakes. This course is walking me through the entire cleanup process and is teaching me where to go to get things done, since I really should not use journal entries to fix problems. Stellar - thank you!

By Shirley P. Linton on 8/24/2021

I feel we needed some resource material to practice especially in correcting the reconciliation from a previous period. Didn’t quite understand what was done with the difference of $100 or $110. Secondly the P & l should show a corrected layout if there was no time to go through all those items that should have been changed to cost of goods sold- raw materials.

By Carolyn Sutton on 7/8/2021

The instructor is knowledgeable, easy to understand and follow, and offers great explanations and step by step examples. Great course to take if you need a little more clarity and a better workflow system on how to clean up messy books.

By Jennifer Ulbricht on 5/3/2021

This is a great course for intermediate learners. I already had a solid foundation but there were significant gaps in my education when it came to real-world application. This has helped tremendously with legitimate job skills. You also can't beat the price. Many of the other courses I looked into were hundreds or thousands of dollars and most of it was stuff I already knew. This is paying for itself already!

By Flora Kozma on 4/26/2021

Having a good time learning so much. I am wondering about the questions area. Does the instructor write back as I have noticed that others have asked questions that I would like to know about too and there is nothing showing.
