I really like GoCardless and agree it's changing the way many of us do business but being a paranoid kind of fellow I like to review potential problems that might occur from the companies I deal with and become reliant on.
GoCardless seem innovative and are currently valued at around £1M. However, since their assets have now surpassed the audit exemption threshold their P/L is now a public document. I'm no accountant but a £3,524,168 loss last year (£2,298,296 loss the year before) seems a bit of a worry.
There are undoubtedly other things going on here that can't be determined from the published accounts but still....
