Avoid. Shop around before investing time & money in a company that over promises and way, way under delivers.
I would seriously think again about using Syrve. As the formerly named Iiko, our ePOS and kitchen order management worked quite well, never functioned exactly as we had been promised, but not too many complaints.
Since becoming Syrve however, and using their -'eatmeonline' ecommerce site for our online orders, we have had no end of problems, which have been going on for nearing a year to date, and have almost almost certainly resulted in losses of thousands of pounds.
Syr've Online Ordering site is the most unreliable software I can imagine is out there, if there is anything less fit for purpose I would be very surprised. The 'support chat' to somewhere in Russia is absolutely atrocious. They try to tell us we're wrong, imagining things, that they haven't been tinkering with the software in the background and causing a plethora of brand new, resultant bugs, that it's all working fine. This is after we have calls from customers unable to use the site. Informing us of bugs and error codes, user-unfriendly features, etc. It makes our business look shambolic. The fixes normally cause even more issues, spiralling into so much chaos and stress we wonder why we ever asked for support, or what the original issue even was.
Most emails to a person at Syvre go unanswered. We've waited for 4 months for a replacement cable for KDS screen, despite numerous emails, not even a reply to requests for what cable we needed so I could buy one elsewhere.
To feel totally ignored, as if is our business and livelihoods are irrelevant is quite shocking. How a company with such an appalling attitude to aftercare, and providing a system that is fit for purpose and bug free, can survive and operate I can't understand.
I suppose it's because once the initial investment in expensive hardware is made the customer is pretty stuck and tied in.
After a year of giving them chance after chance I've had enough. Next course of action is to seek compensation for damages to our business and loss of sales.
We have been used as guinea pigs for a software system that is so for off being workable, or having any degree of reliability, that what we're paying for feels more like a joke - or a scam.
After 2 months of initial setup problems, a high-up even admitted as much, that, 6 months prior, the system was 'unsellable'. I specifically questioned how their business could possibly be surviving, if hundreds of their customers were having the same issues as us; at which point he confessed we were only one of 3. This is, in my opinion, a system in Beta, and my company has quite truthfully been used as a test subject.
Where else would you spend money on something that has such a negative impact on your business?
There really should be a certain degree of guaranteed reliability prior to any product going on sales - as with other sectors - from electronics to cars & toys, where certain standards must be met; it seems with software it's a complete free for all. Unregulated, and companies can get away with taking your money for something that's so badly made it may as well be scrapped.
I'm disgusted with the service and products provided by Syrve.
Thinking about the costs our business has incurred through their incompetence makes me question what kind of world we are living in.
To get 'Sorry for the inconvenience' adds insult to injury. What are these people thinking? Not a lot by the look of it. They have my money, do they care much more than that?
