I'm just starting a new business and have built up a database of 2000 possible clients in Excel. I'm now going to start contacting the companies, sending out mail shots, phone calls etc and I think some sort of contact manager would be useful. If I then manage to sell to any of these clients (a renewable subscription) then I need to keep track of who has paid what, when and when to remind them to renew. All the contact and invoicing software I can find seems excessively expensive (especially the pay-as-you-go services) and aimed at larger business (eg. ACT! and Mamut). Is there any software aimed at SMEs (v.small = me!) with a couple of products but a large number of clients? Many thanks!
