What our customers say
As an SME owner for whom cashflow is paramount, I highly recommend Bluechain. It's simple to operate, 100% secure and wholly reliable. If your SME requires a helping hand whilst waiting for those sometimes slow payments, try Bluechain.
Catherine Butterworth
Business owner, 4 Seasons Garden Maintenance Ltd
Bluechain’s platform has been rock solid for me, but what really stands out are the people behind it. On the few occasions I’ve needed help (all self-inflicted!), the team have been quick to respond, been genuinely helpful, and even gone out of their way to help me out. It’s rare to find this level of care and professionalism these days. Absolutely first class, I can’t recommend them highly enough...
Fraser Morrison
Business Owner, FP Morrison Limited
Fantastic and unique service which I have not seen anywhere else. Has really helped my business with very tight cashflow issues, would recommend them to anyone.
Taha Mohamedali
Business Owner, Alfa Chemists Ltd
Bluechain has been a really useful tool for handling my pharmacy's cashflow. I can always pay my suppliers reliably and on time, and the service gives me the flexibility to not settle the statement myself until the NHS payment has actually come in. That kind of cashflow advantage, plus the great card rewards, easily outweighs the small fee. I'd absolutely recommend it to anyone who wants a much smarter way to manage their money without resorting to expensive loans or overdrafts.
