Make sure you have installed a reliable and an updated endpoint security in your network environment. Beware of malware taking over your resources.

We condensed our company file from 194,740 KB to 103,076 KB. 

Somedays it boots up quickly, somedays I fall asleep waiting.  

In summary, condensing your company data file does NOT improve QB 2020 PRO performance. 

My suggestion is to boot up QB 2020.

While its wondering what it wants to do make yourself a fresh pot of coffee, 

do your laundry, read last week's NY Times.  Come back in 1/2 hour and check the status. 

Has anyone found a replacement for QB 2020 Yet?

QB 2021?

We had QB 2017

We had QB Pro 2017, not 2018

LOL, do NOT waste your money. 

Unless you QB's built in merchant services, payroll or shipping manager, 

you could use a QB version running in DOS. 

I am having the exact same problems you are having moving from 2017 to 2020 QB Pro.  So frustrated.  Looks like you haven’t found a solution.  We have to have 2020 or we cannot sync with our bank online.

We have new computers and server, running Windows 10.  Our hardware, server are not the problems.  The problem is in QB 2020.  After I first installed it, it was OK for a short time. 

Have you found a fix for QB Pro 2020 yet?

I FIXED MY QUICKBOOKS 2020 DESKTOP PRO SLOWNESS!  I went from 2017 to 2020 and it got so slow, I couldn’t use it.  I tried to condense but it didn’t work.  Then, I went to File, Utility and did not use the “multi-user access”.  BOOM - my Quickbooks is now super fast in all parts of the program - just like it was with 2017 version.

Hope you find it helps you too!

We upgraded to 2020 and instantly experienced very slow performance.  We are not happy with the pop up Intuit advertising but can't say that's the cause.

We condensed our data file and followed all the recommendations by QB.  The Start-up of QB is still slow as a snail, and it's random as well.  Never had this issue with the past versions.  It's not our operating system.  It's not other programs running the background.   Ideally, we'd prefer to run QB 2017, But...... ya can't do that.  Once you install QB2020 it "updates" your data file and you can't use it on previous versions. 

 And, since we have a Payroll subscription with Intuit we have to use 2020.  What Intuit does to generate additional revenues is they force you to update to a new QB version every 3 years if you have their payroll subscription.  

Intuit is not a great company it once was.  Its exclusively driven by revenues; short-sighted.  No vision.

QuickBooks desktop 2020 is VERY slow.  I have been using QuickBooks since v. 3.1.  They really need to do something about this issue.  

@Kristine Mortimer 

If you are still using the same company file since QBD v3.1, it is possible your file size is larger than 150-200 MB. Consider to condense or split your file to reduce the size.

I work with many clients.  I am not using the same database as I did back then. lol  I am at 165 Mb and it is still slow.  It does not matter which database I am in or which computer I am on.  It is slow.

Let me step in and provide some steps to boost the performance of QuickBooks Desktop Pro, Kristine Mortimer.

A company file size that is more than 150 MB needs to use the QuickBooks Condense Data Utility to reduce it.

Aside from that, I listed several solutions below to improve the performance of the program.

Solution 1: Update QuickBooks Desktop Application

Follow this article Update your QuickBooks to the latest release.for detailed steps. This makes sure you have the most recent fixes and security update.

Solution 2: Rename QBWUSER.INI File

1. Open Windows File Manager by pressing Windows + E keys on desktop.
2. Navigate to C:\ ProgramData\ Intuit\ QuickBooks folder.
3. Make sure Windows is set to Display Windows Hidden Files.
   

   

4. Locate and right-click QBWUSER.INI file.
5. Select Rename and add .OLD at the end of the file name.
6. Save the file name and try to run QuickBooks Desktop once again.
7. If QuickBooks is still running slow, then follow the next troubleshooting step.
   
   

Solution 3: Verify the Windows System Configuration

Following is the minimum system requirement that needs to be fulfilled in order to run QuickBooks Desktop efficiently:

1. Core 2 Duo Intel processor 2.4 GHz minimum or any upgraded version.
2. 4 Gigabytes of RAM.
3. 5 Gigabytes of free disk space after installation.
4. Optical Drive or connectivity to the internet.
5. 1280 x 1024 Screen resolution.
6. US version of Windows that must be either Windows 10, 8.1 or 7.
7. Installation on a server requires Windows Server 2016, 2012 R2, 2011, or 2008 R2 SP1.

Solution 4: Reinstall QuickBooks Desktop

1. Download QuickBooks Tool Hub.
2. Open the setup file from the downloads of your computer and follow the on-screen prompts to finish the installation.

   

3. Open the file you downloaded (QuickBooksToolHub.exe).
4. Click the Program Installation Issues tab and click QuickBooks Clean Install Tool.
5. Run the tool to install a fresh copy of QuickBooks Desktop application.
6. Use the QuickBooks Clean Install process and reinstall QuickBooks Desktop application on your Windows computer.
   
   

Keep me posted if there's anything else I can help you with QuickBooks. I'll be right here to provide the information you need.

Its amazing how many QB "Experts" post stuff 'suggestions' to questions in this community and they fail to read the thread or past responses.   

Solution 1: Update QuickBooks Desktop Application,   

Been there done that , 100 times

Solution 2: Rename QBWUSER.INI File

Been there is not such file in that location, hidden or not hidden, however my QB has been running with out it there. 

Solution 3: Verify the Windows System Configuration

If you read further back in this thread, my system is over qualified, if size matters, lol. 

Solution 4: Reinstall QuickBooks Desktop

Now, this has got to be the most 'out there' suggestion next to Re-Install Windows. 

But for xhit and giggles we deleted every QB file and every Inuit file and including all referenced

in the Windows Registry, and then some more. Did NOT make a difference. 

So,  Please, if anyone else thinks suggesting a solution, read the first post or the entire thread. 

Thank you for adding additional info of your concern, @kuehl87.

I ran the condense utility.  It still was not running smoothly.  I then uninstalled, rebooted and reinstalled QB2020.  It is now running smoothly.  I will note that when it started to run slow, I had been trying to export Lacerte invoices into QB desktop 2020.  All is well on my end now.  Thanks!

" I (you) know you (I) have already contacted them" 

LMAO !   

Let me tell you what it is like contacting QB Tech Support. 

Last month I contacted QB Tech Support to clean up an end of the year issues with the way QB handles payroll benefits and to move them to the proper fields in a W2.  The way QB made put such a band-aid and work arounds is crazy.   I spent 40 minutes on the phone, in a screen share session, and when I got done things were still the same.  I knew more about the how transactions affect accounts than the Tech Support chap.  Total waste of time. 

A few months ago I contacted QB Tech Support to trouble shoot their built in Federal Express application.   I think they bought the code from another company years ago.  For nearly an hour I was chatting with a young lady in some country and I could hear a rooster kockadoodling in the background.  Sounded like it was in the same room with her.  So I asked her, "Do you have a rooster in your kitchen?"  She responded, "Oh no.  That's the neighbors fighting rooster".   Lol.

So, give us all in the community a break.  Don't post to our questions unless you have creditable knowledge of the products and services.  

Thank you. 

I am having the same issues also. I have been using QB Pro 2011 for years without any issues. I was forced by my accountant to upgrade to QB Pro Desktop 2021. It sucks big time. SLOW.

VEERY SLOW. It takes over a minute to open. WHY?

What could it possibly be doing?

Uploading my data to a server somewhere?

I don't like the feel of it. It seems to be connected to something in the cloud.

My old version was MUCH snappier and more responsive. THAT is the main reason I didn't upgrade for so long. Every time I upgraded, the software got bigger and bigger, slower and slower. I cannot stand this new version.

I called in to "Tech Support" and tried to speak with someone with a very strong foreign accent. This language barrier only made the situation worse. He tried all of the usual fixes and blames mentioned above to no avail.

He then wanted to install some remote viewing software on my system so that he could control my PC.

NO THANKS.

This software has an OBVIOUS issue. Everyone I have spoken with is having the same symptoms.

QB Pro Desktop 2021 is WORSE. Do not "Upgrade" to it. It is horribly slow.
