On the surface this seems to be adequate to do your job; the specifications are rather general, but it appears that you want it only to do normal business work. The CPU will be powerful enough to handle general office programs, the memory is good. I especially like that there are 4 USB3 and 4USB2 ports.
One weakness is that you have only 2 expansion slots, but if are not planning on adding any cards that should not be a problem. There is one PCIe 16 slot so if you decide to add a video card later that can be done.
Since there is a PCIe slot available that means that there will not be a separate video card, so you will have integrated video on the mainboard. If this unit will be used for gaming or video creation, editing and manipulation, then that is not adequate so you will definitely want to invest in a higher-end video card. From what I gather you will not be using it for that so then it will be fine.
I am a bit uncertain about how you will be using this from this statement:
We have a web application that our employees are accessing it on a regular basis throughout the day
Do you mean that this is only going to be a replacement for one of your office units and will be accessing your company website? Or are you attempting to use this unit as a server of some kind?
In addition, be aware that these retail units come totally loaded to the top with pointless trialware, junkware and sometimes spyware that will slow the entire unit down drastically. Off the shelf, you will not get the speed and performance out of your computer that you paid good money for.I am not exaggerating. A few of the usual suspects are Microsoft Office trialware, Symantic Norton antivirus trialware, possibly various McAfee web safety products, and a lot more. In addition, literally all of these computer manufacturers, including Acer, load up on what I call "overlay" screens that "help" you do normal functions that Windows has perfectly good menus to do. As only one example, there will be a "helpful" utility that will "help" you set up a control panel to access and configure your network connections. Windows 10 has a perfectly good configuration screen for that. All of these "overlay" screens load on boot and will drag down the performance of your unit.
I have taken so many of these off of computers that I lost count long ago, and still do it every month that one comes in. You need someone with knowledge and experience to clean up your system before you put it into production, and then it will fly.
