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. Alternatives considered [Rent Manager](https://www.capterra.com/p/2732/Rent-Manager/) Reason 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. Review Source Kate G. Director of Operations/Marketing Director Events Services Used the software for: 2+ years ### "Flex is great for managing our inventory, and communicating with customers each step of the way." April 17, 2018 5.0 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. 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! Review Source Response from Flex Rental Solutions April 18, 2018 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. Jennifer B. Senior Development Director Events Services Used the software for: 2+ years ### "It's 2018, what even is Flash anymore?" April 17, 2018 3.0 Pros I like that it's web-based. Cons It's written in Flash, which is horrendously outdated, and works terribly with my computer/browsers... yes, browsers plural, because I have to use one browser for Flex while I use another browser for everything else. It's painfully slow. It crashes routinely, resulting in us asking support to "restart" the software for us (usually at least a few times a month, and more during our busy season). You can't search for events/quotes by a specific date (meaning, if someone said "remember that job we did at XYZ Venue on January 1st this year?" - to look it up, you have to click 'back' on the calendar repeatedly until the timeframe comes into view... you can't just search by one date). It's inaccessible on iPhones/iPads. Visually, it looks outdated, clunky, and like it was designed in the Windows 2000-era. Customization ability is very limited, so you have to get really creative to make the software work for you/in the way you want, which usually ends with "you can't do that" or compromises (ex: you want to run a report featuring X,Y,Z data. Probably can't actually do that) Review Source Benjamin L. Technical Operations Manager Events Services Used the software for: 2+ years ### "Flexible and Powerful" September 22, 2020 4.0 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. Review Source Response from Flex Rental Solutions September 24, 2020 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! Keenan G. Event Manager Events Services Used the software for: 2+ years ### "Excellent desktop platform, lacking mobile support" April 17, 2018 4.0 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. Review Source Response from Flex Rental Solutions April 18, 2018 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! Carl S. Director of Sales Events Services Used the software for: 2+ years ### "28 years in AV using different rental software" April 19, 2018 5.0 Ease of use for quoting Pros 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 Review Source Response from Flex Rental Solutions April 25, 2018 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. Laura Q. Senior Director of Administration Events Services Used the software for: 2+ years ### "We have been users of Flex from almost the very beginning. We love the customer support!" April 17, 2018 5.0 We are able to do all of our quoting, invoicing and warehouse management in one software. Pros Ease of use, Flex is very intuitive. It works well for what we need it to do. The financial side of quoting and invoicing is an especially great feature. Cons Wish there were more labor timekeeping/crewing/scheduling features. A one stop shop product would be great. Review Source Response from Flex Rental Solutions April 18, 2018 Laura, thanks for your thorough review and for your loyalty through the years. We pride ourselves in having a lot of long term Flex users and we work hard to make sure we keep them. I'm so glad to hear our support team has been good to you! Jason M. Chief Financial Officer Architecture & Planning Used the software for: 2+ years ### "Great tool for rental houses. Processes are easy to follow and learn." April 17, 2018 3.0 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. Review Source Jamie M. Director of Technology Events Services Used the software for: 2+ years ### "Solid organization just waiting for the new version" February 15, 2019 4.0 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. Review Source Keith C. Studio Equipment Manager Used the software for: 6-12 months ### "Fast, Efficient, Robust" April 17, 2018 5.0 It allows my department to function as an independent business! Pros You can build out your tracking/billing needs to meet your unique set of demands. The PDF'swe send to clients (quotes, invoices, etc.) look fantastic and thus, make us look really good! Cons I wish that the HTML5 version would release already. Tired of the current format and really anxious to see where the software is gonna be in the next year. Review Source Response from Flex Rental Solutions April 18, 2018 Keith, thanks for the wonderful review and for taking the time to customize Flex to meet your needs and that the PDFs make you look good. Nothing makes us happier than that. We're really excited for Flex5, too. Hope you've been able to check out the updates on our website and email. BW Brian W. Inventory and Asset Manager Entertainment Used the software for: 2+ years ### "Flex Rental Solutions is the Flexible option" January 23, 2025 5.0 Pros The ability to customize to fit our workflow for our specific needs as a company. Cons There are still features being worked out and there are times where things don't work exactly how they should. These issues usually get resolved in a reasonable amount of time. Review Source KC Kealan C. Producer Events Services Used the software for: 2+ years ### "It’s been a very productive tool for us, overall great software!" December 17, 2018 5.0 Overall, I’m much happier with flex than we were with the previous two offerings. Keep it up! Pros It works! (I’m surprised to see how many people have outstanding issues, we have our fair share but they get sorted out fairly promptly). Web based is a winner, do you remember when you couldn’t do this? And yes, I understand the flash debate, it will be wonderful with html5 but flash has worked fine to date. Agree that you get out what you put into this software. We have spent a lot of time customising it, creating specific reports, documents, workflows, inventory suggestions, etc and it’s all paid off. Yes it takes time but I can’t imagine an off the shelf product working adequately in our custom world of production? Allocating times to labour items is great. Helps massively with rostering. There’s lots of positives to say about this, well done flex team! Cons The lack of html5 support so far. Also an api would make sense so we can integrate with other relevant platforms / software. To channel a younger me, I’m also going to say; custom colours and ‘themes’, background images, etc. as we end up working on it a lot. Review Source JM Jeremy M. Crewing and broadcast technical manager Broadcast Media Used the software for: 2+ years ### "Flex is a deep program that aggregates and organizes a lot of info. It functions but is not optimal." April 17, 2018 3.0 It keeps track of our Barcode Systems and our gear. Pros I like how detailed you can be and how most of the functions that a rental house might need are accessible and available. Almost anything you want to do you can get it to do to some degree. Flex has a deep base of tutorials that are very helpful. Cons Speed. It is slow and adds hours to every week while I wait for things to load and/or populate. The availability of crew and equipment is often inaccurate and it's hard to tell why. The crew lists are barely usable and a whole seperate program is probably a better tool for crew communications. Flex makes it seem like they have the functionality to manage crew but it is not functional on any real scale or complexity. Review Source Response from Flex Rental Solutions April 18, 2018 Jeremy, we appreciate your well though out and honest review. Please feel free to reach out to our support team if availability is not working how you expect, they can troubleshoot that issue for you. Thank you! BB Brian B. CEO Entertainment Used the software for: 2+ years ### "Awesome Rental Software!" June 27, 2019 5.0 Business operations have been incredibly organized now that we have this software. Pros We love that our company can keep track of our rental inventory , knowing where everything is at the moment needed Cons The Accounting feature is nice as it’s works with QuickBooks and other accounting software. But... one thing I wished they would change would be to have the ability for multiple invoices to be paid by one check. You have to go through a process of crediting an account just to do this. Other than easily showing what is owed all by that one customer for a single payment to be made and exported to your accounting software. Reason for choosing Flex The other products that were researched used one large expensive server where as Flex uses Flash and updates in their own server charging only a monthly fee. Review Source daniel U. wearhouse technician Entertainment Used the software for: 2+ years ### "when a company has everything under barcodes flex is so easy to use and easy for inventory" April 17, 2018 4.0 for wearhouse use i think its the easiest software to use Pros it helps me know if a specific product is available or not and and if not then when will it be available Cons some options dont come with instructions on how to use and that makes it very difficult for some of us to be able to manage or use flex to our ability Review Source DO Danika O. Director of Business Development Events Services Used the software for: 2+ years ### "Used this software while working at a lighting/video company, now using it at an Event Decor company" April 17, 2018 4.0 The current company i'm working for had no inventory system at all, this is a big step up for them and I'm confident that Flex can adapt to the company's needs as the company grows. Pros I like having a database where anyone an go to find out information about a specific show, inventory questions, and being able to track assets easily. It's offers a lot of customization options for each business. Cons Quickbooks online integration is not complete. Header titles don't update across all documents if you change the name of a quote. Cannot edit the layout of reports very easily. I can't wait for the HTML5 version to be released, i'm hoping a lot will be fixed in that version. Review Source Response from Flex Rental Solutions April 18, 2018 Danika, thank you for wonderful review. It's one thing we keep hearing about how customizable our software is for our customers and I'm glad you trust Flex to meet your needs. JK Jordan K. Owner Used the software for: 1-2 years ### "Industry standard, but needs some love" August 10, 2016 4.0 It has all of the quoting, invoicing, inventory management that a production company could use. Fusing flash in 2016 is a little insane, but hopefully Flex 5 is released shortly. Pros It has a full feature set and is purpose built to fit the needs of our business. Cons Flash, in 2016.... Seriously. Mega lag with scanning and hangs on 5% of barcode scans. 1/20 scans requires click in the 'processing' box or a full refresh of the browser. Review Source Response from Flex Rental Solutions August 11, 2016 Hi Jordan, Thanks for your review and for letting us know about your scanning issue. That is certainly not common and definitely something we want to resolve. Randy connected with you yesterday and provided some recommendations to help with that, and after talking with you today, it sounds like things are as they should be without those lags. We are always happy to help resolve issues when they arise - please do not hesitate to reach out to us at support@flexrentalsolutions.com or 801-420-1706 x 2 for assistance. Thanks again for the review. We're excited with you to show V1 of Flex 5 (HTML5) soon! Stay tuned :) RD Ryan D. Production Manager Entertainment Used the software for: 2+ years ### "love the functions of it. Sometimes wish it was faster. Cant wait for HTML 5" April 17, 2018 3.0 The ability to manage our inventory and quickly see where we are short. The ability to make larger quotes as our old software was limited to 15 lines. Pros It's not our inventory on an excel sheet. It is super helpful in finding shortages and helping to resolve them. Our customer rep. and the team have been fantastic to work with and talk to. Cons Learning curve for some of the finer features. Timing of new updates sometimes can seem slow. I wish some of the customization was easier to do without custom programming or learning. Review Source Response from Flex Rental Solutions April 18, 2018 Ryan, thanks for the thoughtful review. We pride ourselves in delivering a great customer experience. Since our software is so customizable, it does take some learning, but we found a lot of our users really benefit from the videos, webinars and other training resources. EH Eddie H. Project Manager Events Services Used the software for: 6-12 months ### "Using Flex on a daily basis to create quote" April 17, 2018 5.0 The software allows us to have everything in a central cloud based location that is easy to use and access from anywhere and easy for anyone with the proper permissions to view the information they need to from wherever they are at. Pros We love that Flex has allowed us to create quotes that have a professional look, especially with the custom report options. We are looking forward to being able to take the quotes and start pushing them to the logistics team sooon to see how we Cons The program in Flash is laggy and sometimes takes a very long time to load, especially on larger documents. It would be great to see the program work better and even better if it moved away from Flash all together. Review Source Response from Flex Rental Solutions April 18, 2018 Eddie, thanks for the detailed and honest review. I'm glad the quotes, functionality, and custom reports are allowing you to run your business and deliver service how you want it. RT Rochane T. Manager Used the software for: 2+ years ### "using for 6 years, recently did training course, all permissions now, have control of my own stock. " April 17, 2018 5.0 it is easy to navigate around the software. the customer support is really good and issues are resolved fast. Majority of AV companies are switching over to this software so If I did leave this company there would be a good chance they would be on flex. Pros can be accessed anywhere internet is available. most AV companies are using this software now so receiving quotes or invoices has a familiar layout. Cons dont like java too slow but i know everything is being switched to HTML5 in the new flex update. :) Review Source Response from Flex Rental Solutions April 18, 2018 Rochane, thank you for the wonderful review and for investing in training. We do find that customers who take time to learn the software are able to optimize its use for their particular way of doing business. AC Andy C. Video technician Used the software for: 2+ years ### "Flex has a bit of a learning curve, but once you get the hang of it, it is definitely both powerful." April 18, 2018 4.0 Pros In my experience, flex is reliable and diverse in its applications. It does a many different tasks that are important in our industry. Cons USER INTERFACE. It appears to me that very little thought was put into the UX aspect of flex. It takes a very long time to be trained in flex. I personally did things the hard way for many months before even realizing that there was another way or a feature that made a task easier. Also: html5.... get it done, please!!!!! Review Source Response from Flex Rental Solutions April 19, 2018 Andy, thanks for the thoughtful review and that you're finding our software powerful and reliable. Check out our website for announcements on Flex5. DS David S. Creative Director Entertainment Used the software for: 2+ years ### "Powerful application, difficult interface" April 17, 2018 4.0 Inventory control and a system that is designed for this industry. Pros I like the flexibility. It's so flexible that it's actually too complex to use sometimes. I have a degree in user interface design so I get overly annoyed with using it, but I think most people work around the quirks. My employees manage their way around by finding their own way of doing things. Cons The interface, the fact that I spent $20 on an iPad app that is essentially useless. It's heavy. Literally cannot wait until Flex 5 is made public. Knowing Flex 5 is coming is the only reason I stayed with it. Review Source RN Rob N. President Used the software for: 2+ years ### "Flex is very good inventory management software for the entertainment industry" April 17, 2018 5.0 Pros Multiple users, fairly quick inventory results, good reporting, a large amount of information available to be entered about each product, allowing good tracking Cons It does not have a nice graphical interface. I wish it worked with IOS, which I know is coming, but it's about a year so far since they suggested we would have it. I would also like a better crew scheduling module, something way more graphical. I am using Ximble Review Source Response from Flex Rental Solutions April 19, 2018 Rob, thank you for the thoughtful review and that you're finding our software comprehensive in the amount of data you can have about products. MG Mike G. Technical Director Entertainment Used the software for: 2+ years ### "I think Flex is a powerful tool. I use it for inventory management and to write proposals." April 17, 2018 4.0 Inventory management is number one for me. Pros The ease at which I can build proposals. The accuracy of inventory management. The systems in place to solve conflicts quickly. Cons It's very slow. It is frustrating sometimes. Every third time or so I'll drag an item into a proposal and it won't "stick". That's frustrating. Review Source Response from Flex Rental Solutions April 18, 2018 Hi Mike! Thanks for the great review. We're elated you find Flex a powerful tool to manage and grow your business. Our dev team is working to resolve some of the speed issues, but if something is not working how you expect feel free to reach out to support. EÅ Edvin Å. Ljustekniker (Lighting tech) Used the software for: 2+ years ### "I do enjoy using the system, the fact that I can work from home" April 18, 2018 4.0 Pros The flexibility! I can just like with the MA2 change it to my liking and the fact that my colleagues can to without affecting me is a Very big plus in my book! Cons Some features are harder to use and not so obvious. For me as a Swede having English as my second languish some features take time to understand what they do. It is great then that there are the youtube videos to watch and learn. Review Source Response from Flex Rental Solutions April 19, 2018 Edvin, thank you for the positive review and that you're finding our youtube videos and tutorials useful.
