Before making an investment in anything one of the things you should consider is why do you need the item, and how will the item accomplish your end goals. You are now considering purchasing a product of Intuit, either one of their financial packages or a Point of Sale Package.
Some things to consider in this are the end goals, number of users, growth capabilities and cost. Intuit offers several different financial packages: Pro, Premier, Enterprise, Online.
There are differences in the products and the costs and what each level can do. For example Pro is the least expensive but seems in my client base to be the most used. The limitation is the number of concurrent users. Pro is limited to three (3) users. The cost is normally retailed in the $220 to $230 range per user license.
Premier is the next step up at about $400 per user. On this level you can have up to 5 concurrent users for a total price of about $2,000. Both Pro and Premier have upper list limits of 14,500 while the next version ranges into the 100,000 area for about $3,000. Both of these version have about 10 security levels that are rather limited to general categories. While both Pro and Premier have low user limits Enterprise is scalable up to 30 concurrent users. This version has about 115 very specific permission levels and these can be customized and assigned to different level of employees.
The current version of POS come in both the Basic and the Pro edition. The Pro is required for multi-store environments. Both of these will integrate seamlessly with any of the QuickBooks financial offerings except the online version.
Once you have selected your POS Software then it is time to select you Accounting or Financial Software. The integration from one to the other should be seemless as indicated below.
