Thanks guys

Hi Dazmond - I'm a tad biased of course but it sounds like taking Cleaner Planner for a spin would definitely be a smart move for you.
If you're used to using the PDA with George you'll find CP works in a similar way. You download your worksheet(s) at the start of the day, work offline during the day and upload when you get back in. On the Samsung you won't need 3/4G just wifi in the morning/evening as the app works 100% offline during the day.
Email invoicing is fully integrated into CP, you don't need to leave the software, if you have a business email address then we hook that up directly to CP so you can email PDF invoices (with your logo) directly from CP, no need to export the file attach it to an email, type in the customer's email address etc etc = big time saver.
Backing up - I backup your database hourly but for your own peace of mind you can also download a ZIP file of your entire account (e.g. to put on a USB stick) whenever you want, and if you go for the Pro package you can backup your entire account across to Dropbox with a single click! That way it's backed up to your own cloud space and sync'd down to your PC/Mac as well. In short - if your phone or laptop dies it will have zero impact.
Anyhoo, if you fancy giving it a go or you have any questions feel free to get in touch and I'll talk you through it
