What marketing has worked best for you?

Am I missing anything?

I’m stuck with software options? I would like to be remote and work from home. I have looked into xero and QuickBooks but they don’t appear to be able to process batch supplier invoice. I am good with systems and pick things up quickly. I use sage 50 at work and I like it, is there cloud software that offers this level of package?

Also what is the best most secure way to share documents?

Thank you in advance. Any help, advice and information is much appreciate.
