QuickBooks Over VPN Runs Slow - How to Optimize

If you go by what has been said by the popular communities, then you will find that most people believe that QuickBooks cannot be run over a VPN connection. But in reality, you can, though it is not generally recommended, which is another thing. Let’s look at what you should know if you want to use QuickBooks over VPN.

A small business owner called us to ask about giving his team access to QuickBooks Desktop Software over a VPN. He could not switch to QuickBooks Online due to the lack of required features for his type of business. VPN issues for QuickBooks are not uncommon, and we do not recommend such quick and dirty setups. Instead, we recommend Remote Desktop Services for QuickBooks, which is more reliable.

Keep Things in Mind Before Using QuickBooks Over a VPN Connection

1. When you plan to use QuickBooks over VPN, the most important thing that you should consider is the speed of the internet both at the remote location, from where you are going to connect as well as in your office. Ensure that the speed of the internet is high on both sides otherwise, the performance will suffer for sure. No matter how good the internet speed is, by connecting QuickBooks over a VPN, the speed will surely slow down.
2. The second important thing is the number of users getting connected through VPN. As more users get connected with QuickBooks over VPN, you will need a greater as well as faster internet connection to ensure that things work well. In case two users are going to get connected through a VPN, then you should have a faster connection.

QuickBooks Over VPN Runs Slow - How to Optimize?

Solution: Fix Memory and latency issues, QuickBooks Over VPN Runs Slowly.

• When QuickBooks launches on a laptop, the daemon redirects file share traffic through a "QB managed" port.
• It still relies on file sharing and client software to load the QuickBooks data file into local memory.
• If multiple users access the same shared file over a VPN, continuous read and write operations may cause errors.
• A VPN adds encryption to file share traffic, improving security but increasing latency.
• Latency is the time a data packet takes to travel back and forth.
• On a local network (LAN), latency is usually under 1 ms.
• Over a VPN, latency can reach 100 ms or more.
• A 40MB QuickBooks file contains millions of packets, making high latency a problem.
• This slows down processing and affects user experience.
• Remote Desktop Services (RDS) offers a better solution for QuickBooks access.
• It keeps traffic between the user's laptop and the shared QuickBooks database within the LAN.
• It does not route or encrypt data through a VPN tunnel.
• If using Hyper-V VLAN switches, data stays on the same physical machine.
• This setup is faster, more stable, and more secure than using a VPN.
• Keeping data transmission local improves performance and reliability.

What is Virtual Private Network (VPN) In QuickBooks & How it is Important?

QuickBooks does not support VPN in all the versions but firstly a VPN is a virtual private network that is used privately by a set of people who can access QuickBooks with the same access. Such networks are built when there is a requirement that the people who are involved in the business will have access to the private network so that whatever changes are being done they are directly updated with everyone in the VPN.

In such cases, QuickBooks does not support all the versions but yes in QuickBooks 2013 all the editions it was there to use a VPN.

Why VPN is Required?

1. To keep track of all the databases with sharing and security.
2. VPNs are privately used so the data loss is not there.
3. It has the option of connecting the QuickBooks to different devices at once
4. Such networks provide ease of data access.
5. An error fixed in a single system would be removed from the entire network.
6. It gives the confidentiality of the products by keeping all in a private network.

QuickBooks Desktop Isn’t Designed For Remote Access

QuickBooks is primarily intended to be used remotely through the use of Remote Desktop Protocol (RDP). Although the term VPN (Virtual Private Network) is often used interchangeably by IT professionals when discussing remote network access, it's important to note that most VPNs are better suited for transferring data files such as Word documents, Excel spreadsheets, PDFs, etc. They are typically not optimized for live database applications like QuickBooks, which require fast and reliable connectivity.

Connect QuickBooks Not Via VPN

One common error is installing the QuickBooks client on a laptop and attempting to establish a connection to the business server through a VPN. VPN connections typically offer upload speeds ranging from 5 to 85 megabits per second (Mbps), while download speeds can reach 50 to 100 Mbps. However, QuickBooks requires a continuous and fast communication rate of at least 90 Mbps, both for data sharing up and down. Most Local Area Network (LAN) systems operate at speeds of 100 Mbps or higher, even reaching gigabit speeds.

Using a VPN for QuickBooks can introduce delays in data transmission, which in turn increases the risk of data errors and corruption. If you require remote access to QuickBooks for working from home, it is advisable to avoid relying on a VPN. VPN connections have two primary limitations:

• Unreliable
• Too slow

QuickBooks data files will be corrupted if you attempt to use them over a VPN line. It may not occur immediately, but it will happen.
