Having trouble with invoices

So I'm desperately trying to get away from quickbooks because I need a cloud based solution that also has a good mobile invoicing system. Zoho invoice has really impressed me, so now I'm signed up. Downside is that I have to enter everything into zoho invoice, then my bookkeeper has to enter everything into quickbooks. All work is doubled. Zoho books looks really nice. I know it doesn't do integration with banks, but my bookkeeper hated that feature anyways because qb would dupe stuff, or miscategorize it.

I have done about 7 invoices in zoho invoice now. When I first started the trial of zoho books it imported the small amount of data I had in zoho invoice automatically. Is there a way to have it automatically keep in sync? I can't find any way to import the data again.

I have asked support already if I can use the mobile app to just invoice out of zoho books and was told I coudln't. I'd be willing to pay for the invoices package on top of zoho books if I could pull the invoice data into zoho books.

Anyone else doing this, or have any idea how to do this? It seems such a logical step to me, but it seems no company fills this niche very good. Every service company on the planet with salespeople or technicians in the field have to do a paper or temporary digital bill or quote, then enter it again back at the office. Getting rid of this double work would be great :).
