Royal Hospital Chelsea

We were looking to implement solution to as to how to maximise fundraising income from audiences at our ‘Live at Chelsea’ concert series. Traditionally income would be generated through bucket collections but this year that was no longer an option so we need to find a solution quickly.

Supported Giving quickly set up a ‘text to give’ number and QR based mobile site to receive donations, working with our internal team throughout the lead up period and during the concerts. They were always available and I am delighted to say against our initial expectations income generated actually exceeded previous years bucket collections. The data collected offers us the opportunity for a conversion rate to yield additional life time value. I have no hesitation in recommending Supported Giving.

Quality Telecom is an established provider of telecoms and digital solutions to companies in Spain. We then had a specific customer service solution requirement for a major travel company, using 0800 and call routing through IVR to our SIP gateway in Spain, which we needed to get up and running quickly for the UK market.

Supported Business responded quickly to our needs and had the solution tested, up and running in days. We are happy to count them as our partners and first point of contact if we need any telecoms or digital solutions, in the UK.
