OneAdvanced - The Mailbox - Birmingham Reviews 41

It was a pleasure working with Srinivas to resolve the issue we were experiencing with our software. He was professional, approachable, and communicated clearly throughout the process. He quickly identified the cause and helped us get everything back on track. In the end, there wasn't actually a problem with the software—we simply needed to allow a little more time for the process to complete.

I experienced an issue with raising free form orders from the Purchasing (Marketplace) system to order essential STEM products. Jessica Mistry from One Advanced was very patient and worked through and resolved the technical issue with myself and a colleague providing professional and diligent support. Jessica is a credit to herself and her organisation, One Advanced. Thank you, Jessica.

Nikki showed good knowledge, courtesy and professionalism. She took her time to answer my queries Thanks to her.

I would like to thank Andrew Stanford for his engagement, communication, and willingness to escalate issues internally this helped maintain momentum on several critical tickets. His level of responsiveness made a meaningful difference during a time sensitive and high pressure period, and it was reassuring for both IT and Finance colleagues to know issues were being actively monitored. We especially appreciated the regular updates, prioritisation of high impact issues, and coordination across teams when development input was required. Thank you for your professionalism, commitment and support.

Overall my experience with OneAdvanced has not been a good one, they purchased three products I used so had no choice but to contract with them or change all my products.
Their contract management is extremely poor, bearly hear from anyone, even when we have issues we get ignored for months on end, latest contract issue was raised early March, had a couple of holding responses in April, but only after I chased, and its me that has to keep chasing to resolve issues, even when we owe them money as their billing teams are equally useless and get it wrong with almost every renewal. Their Vice President who previously worked for one of our products is equally as ignorant, whether emails are copied to her or directed at her.

The products used to get regular improvements based on customer requests before OA took over, now they simply go into a black hole of 'ideas' and never actually materialise. One product has been in 'early adopter' phase for over 2 years, originally promised over 3 years ago and is still only part of a product regularly linking back to an archaic system from 25 years ago, as they prefer to prioritise their own agendas for AI implementation and areas they want to 'sell' rather than what existing customers have actually asked for.

There are a few and I really do mean a few, staff who are extremely supportive, Carl Fisher, Mike Drive and Gavin Willis but the majority of their support staff are either inexperienced, incompetent or basically ignore you. They only get two stars and not one, because of these few individuals who regularly rescue me when they make changes in one area that affect another, like an unrelated team turning something on and locking my 1,500 users out of another system with the team causing the issue ignoring us and one of the stars having to rescue me.

As an organisation, customer satisfaction is at the bottom of their list, which is why we have already ended contracts for another three products over the last 12 months. If you have a choice, seriously consider an alternative unless you are happy with overall sub-standard support and systems.

great experience and Nikki was very helpful.

Roopa helped resolve very quickly.

Amazing help today, Harshith set up a teams call so we could screenshare and talk through my case. He was very polite and knowledgeable as always and helped solve the issue I had. Harshith Raju thank you!

The OneAdvanced team has provided a very good service in response to the support queries I've logged over the last year.
Jessica Mistry and colleagues often reach out to understand the nature of the request and for the most part resolve them in good time.

My consultancy firm has subscribed to V1 software for the last decade. We were told this year that V1 Project Accounting software was now on "extended support" resulting in "no further new developments for the product". That only occurred after April 2025 as OneAdvanced were issuing invoices for payments which were invalid. No alternative solution has been provided by OneAdvanced.

Since then, there have been significant issues with those invalid invoices being reissued along with an unresponsive account and finance teams to resolve matters that are solely of OneAdvanced's creation.

My firm was recently issued with a new subscription for January 2026 in November 2025. That subscription doubled the cost of the now "extended support" software, with no warning or explanation. That was contrary to advice received from OneAdvanced in August 2025.

An alternative is now required causing significant business disruption to my firm at a difficult time of the year.

Please avoid their "services" at all costs.

Matt is great when dealing with bespoke technical changes to the system, something that is very useful for us as a special needs setting. We get a lot done in good time and solve a lot of issues/queries

From the moment Manikanta Kuppa got involved, my issue was resolved. He provided very positive customer service, and I can’t thank him enough for his speed and dedication in getting the problem sorted.

That said, TMS still needs to address other ongoing issues, as I’ve been waiting for months for my project to be completed.

Very prompt response from Harshith Raju very quick response from the time my case was logged to receiving a call. We set up a teams meeting and he was on time for same. He resolved the issue very quickly. He guided me so next time I know how to resolve which is very, very helpful. He was very polite on the call. Thank you Harshith.

I am sure this company will do anything for you if you are thinking of using their services, however if you want to cancel it is a whole different matter. The assigned manager is different from one month to the next, they ignore your queries, they never call back and continue to send invoices 8 months after you have asked them to cancel. We even contacted them to cancel licenses over four years ago and emails were ignored and hence still charging for 13 licenses instead of the four required. We have sent numerous requests and emails and received little to no response. If you are looking for a company to assist you then please do not choose OneAdvanced!

Matt is very knowledgeable not just in the product but how things work behind the scenes with regards to funding rules and regulations as well. Because of this he can some times be a little hard to get hold of due to a busy schedule.

Rahul has been a great help.

Thanks to Rahul for being proactive and helping out. You've taken an open approach and messaging me to avoid unnecessary delay.

Refreshing to see this approach which beats waiting days for responses on cases.

With you I feel heard.

To be able to talk through issues and work together to resolve them is much appreciated.

Terrifyingly incompetent.

The 'Fawlty Towers' of hosted software service providers.

Home to, probably, the most pointless job in the UK - a Customer Account Manager at One Advanced.
