QuickBooks Online Inventory Management (Udemy.com)

Learn Every Possible Thing That You Could Ever Need When Managing Inventory In QuickBooks Online

4.6

Last updated April 2026

Our take

Based on the ratings of 97 students, a sample of their written reviews and the syllabus, as the course stood in April 2026. No course pays to be reviewed.

This is a focused, 4.2-hour walkthrough of inventory in QuickBooks Online, spread over 23 lectures. The description says it was built on the Plus version, and that Plus, Advanced and the accountant edition are the only plans that track quantity on hand. It covers item types, purchase orders, invoices, vendor bills, returns, reports and fixing mistakes. It also adds some FIFO costing theory and the periodic method. The requirements list assumes you already know basic QuickBooks Online transactions.

Students mostly praise Mark Smolen's teaching. Words that keep coming up are clear and detailed, one reviewer adds plenty of examples, and another liked the audible voice. Another says it covers odd transactions that rarely happen but still matter. The complaints are small. One reviewer felt it ran long on simple topics, another hit a few outdated steps that needed some googling, and a one-star review points to typos, including an expense that should have been COGS. A three-star reviewer said it did not match their version of QuickBooks.

It was last updated in April 2026, after the outdated-step complaints were posted. The rating is 4.6 from 97 reviews, and 63 of them are five stars. It stops at merchandise, though. One reviewer wanted a follow-up on raw materials and work in progress for manufacturers. For a shop, store or distributor on QBO Plus, it looks like a solid, short fix for inventory confusion. Anyone else can pass.

Best forBookkeepers and small merchants who know basic QuickBooks Online and now need to track stock quantities correctly.
Skip it ifYou run a manufacturer needing raw materials and WIP, or you use a QuickBooks version other than Online.

Pros

  • Covers purchase orders, returns, reports and error fixing in one place
  • Reviewers call the teaching clear, detailed and full of examples
  • Updated April 2026 and rated 4.6 across 97 reviews
  • Explains FIFO costing and the periodic method in plain terms

Cons

  • Assumes you already know basic QuickBooks Online transactions
  • Reviewers report typos and a few outdated steps
  • Built for QBO Plus, with no manufacturing or WIP coverage
I always feel confident in the material upon completing the videos. He is detailed, thorough, and gives plenty of examples.

Labeled All Levels, but it assumes basic QuickBooks Online experience and suits bookkeepers or owners handling stock.

Course Description

This QuickBooks instructional course will give you everything you need to know about using the inventory section in QuickBooks Online Plus Version, Accountant's edition or QBO Advanced. These are the only subscriptions that track inventory quantity. You will be a great expert in everything that relates to buying and selling or generally managing merchandise when using QuickBooks Online. These videos will give you the best possible explanation for every topic covered.

You will learn about the list of products and services in QuickBooks online. This will enable you to add “non-inventory” parts to the items list and when to use non-inventory parts. It shows how to activate the QuickBooks inventory module for tracking quantities on hand for your merchandise. Every conceivable inventory transaction is covered in this course. This QuickBooks tutorial shows how to record sales both for credit with invoices and for cash as well as purchases of inventory "for credit with vendor bills" or for cash. It will show how to use the purchase order feature and purchase order reports to track the back orders in QuickBooks Online.

Inventory returns are transactions that many people have trouble understanding. This course will make procedures for customer returns as well as returns to your vendors in a clear and simple way.

You will see how to use inventory reports and how to find and fix inventory related mistakes. You will learn how to adjust inventory for uncommon situations. You will also learn my expert method, created by me, to handle PREPAID INVENTORY transactions.

This QuickBooks Online training course also teaches some basic accounting inventory concepts; All accounting programs use the "Perpetual" inventory method of inventory costing. It will be clear in common sense terms without any accounting knowledge. You will also receive an overview of other accounting theory that relates to inventory. You will leanr things like how QuickBooks Online will calculate the changing purchase cost of merchandise using the “first in , first out” (F.I.F.O.) costing method. You will also learn, in the best possible way, the other method of inventory costing, the “periodic” inventory method. So, if you need to, use the periodic inventory method and help you make your cost of goods sold adjustment to find your gross profit.


The course has been made with QuickBooks Online Plus Version. However, the ideas apply to QuickBooks online accountant and Advanced.

I'm always available if you have any questions or concerns. I hope you learn well and enjoy the course!

I have 3 decades of experience teaching Computerized Accounting. I have taught QuickBooks at A.S.A college in Manhattan New York. I have made my lessons available to certified job training schools for adult education and have helped place hundreds of students in good paying jobs using QuickBooks and other software that they learned in my class.

I am a permanently licensed teacher by the New York State Education Department. I am also a Certified QuickBooks Pro adviser for 2 decades. I have made these videos by determining what my clients needed.

I wanted to help anyone using QuickBooks be prepared for the real-life, hands-on challenges that come with mastering the bookkeeping function of any company. I will prepare you for real life QuickBooks situations that can be challenging or frustrating if nobody shows the tips and tricks that will make using QuickBooks a fun task

I enjoy helping students turn frustration in to a feeling of comfort and satisfaction with QuickBooks. I'm always available to my students when they need me.

The course was very helpful. I would however like to see a course in the work around of inventory when your company is a manufacturing company. How to bring in Raw materials, what to do for WIP and then bringing in the final product to be sold.

By Wendi Nawalaniec on 3/25/2025

Typos; setting up an expense when it should be a COGS. Every course he does has typos. Why is that?

By Elizabeth Kaplan on 11/1/2024

I have taken several courses from Mr. Smolen, including one that had errors in it. I continue to sign up for and take his courses because, despite such errors, I feel like there is no better instructor to teach the material he teaches. I always feel confident in the material upon completing the videos. He is detailed, thorough, and gives plenty of examples.

By Calvin Jones on 7/1/2024

I don't know how long it would have taken me to learn Quickbooks Online, if not for Mark Smolen courses. Thank you for your time.

By Mark Jones on 4/28/2022

It was a good balance. I felt it went a little long on some topics that I thought were pretty simple. But overall very informative with a good pace.

By Edwin Gomez on 4/10/2021

This course has been very helpful in understanding/ inputting transactions. The instructor is very clear and explains the lessons very well. Really enjoying the lessons so far!

By Ivana Bunjevacki on 6/13/2020

Very practical and to the point. Transactions that are often moot in practical day-to-day running of the business are also included. Everything is presented in a clear and easy-to-follow way.
