UKFSN uses Kashflow for our accounting requirements. It’s a good service and I like it. Recently Duane, the founder of Kashflow, announced a new facility to make it possible for us to collect payment from our customers via direct debit using the services of a new payment services company called GoCardless. I’m working on this right now.
As it’s a new company there isn’t a whole lot of software out there to integrate with their service. They do publish a client library to interface with their API but it’s in Ruby and I don’t do that so I have begun writing a client library in perl.
The UKFSN github repository shows the work in progress.
