Pros:

Gives opportunity for life to not take over living, especially things get tight and you need a quick solution to help make lemonade.

Cons:

First time using app given debit card information - unable to use routing and account number and takes a while to actually get set up.

Reasons for choosing Flex

My company actually used it so I tried but they did give the option for routing number and account number so I may use them next as I pay additional fee 4% when using a debit card.

Flex is great for managing our inventory, and communicating with customers each step of the way.

It streamlines our business. It makes tracking, maintaining and managing our inventory easy. It also improves our corporate image and streamlines our customer communications. Lastly, it holds everyone working in the warehouse responsible for their work and accuracy of orders by tracking their scans.

Functionality

Pros:

Flex makes it easy for our account managers to build quotes and communicate that information with customers. Which then easily translates into documents for our warehouse team to prep and prepare orders. It is also wonderful to have the ability to document maintenance, damaged or broken items and losses for each event or rental. The customization capabilities also mean that we can really make the software our own and create documents or work flows that work best for our company. We aren't stuck with a cookie cutter solution that only fits some of our needs. Additionally, the support team is on top of it. They can help with a wide range of questions or issues and are very patient and detailed when explaining how to do something.

Cons:

The customization can be daunting. There are SO many options that occasionally you can accidentally make changes you don't intend to. On this vein, the software is also ever changing. Which is AWESOME, but as a small business it can be difficult to keep up to date on the changes and new features. Overall we don't have any big complaints. Our dislikes are all features... There are just so many features that it is hard to master them all!

Vendor Response

Kate, thanks for such a wonderful and thoughtful review of Flex. It makes us so happy hear about all the wonderful ways you're using Flex at Mastermind.

A GREAT Rental Platform for the right company

Flexible and Powerful

You will get out of Flex what you put into it. With Flex 5 (HMTL) in open beta now: the future looks bright for the platform. As my companies Technical Operations Director: I use Flex daily to track our inventory per project. It's been a powerful tool and a mainstay for us.

Pros:

Flex is, as the name suggests, highly flexible: it adapts to your needs from an inventory management perspective. Tracking projects, inventory, and maintenance are a breeze.

Cons:

The migration to HTML from Flash has taken significantly longer than originally projected. Using Flash has significantly slowed down reaction times through the program and often results in some irritating bugs.

Vendor Response

Thanks, Benjamin, for leaving us a review. We're so glad you have found Flex customizable and able to adapt to your unique needs. We are so excited for Flex5 and where it's going and we're happy that you're along for the ride. We can't wait to show you more!

Pros:

Software's Ease of use, multi-user (seamless ness from Warehouse to Warehouse). Every function we would need to perform from a logistical standpoint we can.

Cons:

Software lags from time to time. Also tends to crash and/or freeze via Mac OS X from time to time (particularly when tweaking invoices). Also wish you guys revamped the mobile app :) came out and then was abandoned - we rely on it for our smaller Warehouse locations.

Vendor Response

Hey Keenan! Thanks for the awesome review and that you're finding our software easy to use for your business. Our dev team is working hard to address the lags and reliability side of things. Stay tuned!

Well thought out for both quoting and logistic. Work flow for an event is a great asset (child documents etc)

Cons:

Sometimes it takes a long time to add items Server down time is sometimes bad, I don't know if this has to do with our size and number of users. Sometime it takes a long time to add an item

Vendor Response

Carl, we so appreciate the time you took to submit a review. Thanks for your feedback and comments on ease of quoting functionality and load times, it's something that is top of mind for us. Thanks for being part of the Flex family.

Great tool for rental houses. Processes are easy to follow and learn.

It is the best product that I know of for rental management. The limitations of it are justified by the affordable price.

Pros:

Inventory management makes sense; there are more features than I'm aware of. The process from Quote to Invoice Collection is quite fluid and natural.

Cons:

Filters are not always the most helpful and it takes time to find an accurate history at times (but I may be doing it wrong). I truly wish our crew could use this software on their mobile devices rather than always having to haul their computers around.

Solid organization just waiting for the new version

Flex has been a hassle to work with due to it's flash-based programming, but the growth towards HTML5 is exciting because the program is a super solid and incredibly powerful tool.

Pros:

Great organizational tool with some really advance features. Gives a ton of control and abilities to pull reports and generate custom info. Easily deployable to a team and quick initial learning curve of the basics.

Cons:

Current version is flash based, making it slow and horrific to work with. The new HTML5 version is expected soon and seems to fix these issues.
