Reviews of Sage 100


Extremely strong accounting solution; very strong distribution solution; not ideal for manufacturers looking for shop floor management. There are so many features built into this product I cannot imagine anyone using all of them. It is very easy to use and very intuitive. Reporting needs to be improved in terms of easy access to the data, but if you opt for the SQL version, you’ve a lot more options for reporting. There are also a ton of third-party integrated solutions to bolt-on, if necessary.

The good: My favorite thing is the accounting. I am a CPA and it works the way accounting is intended to work. You enter your data in temporary data entry files, review the entries and then post them throughout the system. If you make a mistake, you repeat the process to undo what you did. Data integrity, control and audit trails are critical for me.

The bad: Reporting. There are plenty of canned reports, but most of them simply don’t go far enough. Writing reports with Crystal Reports can be a problem if you don’t know how to use the Crystal Reports.


Basically I bought it for payables and payroll.

The Good: It is easy to use.

The Bad: I haven’t found anything so far.

A representative from Trappist Caskets says…

An comprehensive accounting program intended to serve most of your businesses data collection and reporting needs for a wide variety of tasks.

The good: The Bill of Materials and inventory functions were a vast improvement.

The bad: The inability to edit things after updates frustrates or employees.

While the reporting system is extremely flexible the learning curve is very steep.

There are way too many dates in this software, the ability to have checks, invoices & bills dated on one day but posted to G/L on another has caused us problems.

Data entry and retrieval can be cumbersome, finding information requires you to understand the system. In general it is not user friendly.


Very intuitive and easy to learn. Covers the necessary accounting solutions required for today’s business, including financial statement documents, inventory modules, purchase and sales orders.

The good: Simplicity to add gl accounts, easy to follow menus

The bad: Learning to incorporate different types of invoicing was a little challenging but was easy to use after instructions were given.


Easy to use, but still able to get great information from data

The good: The ability to create our own financial reports with the FRX feature that came with program.

The bad: None that I can think of right now
