Thanks Matt and Dave.
Slap bash - any questions on the different packages just give me a shout

James - yep, clean frequency and notes would be imported. I'm not 100% sure off the top of me head if George exports specific week/day settings but this is certainly something Cleaner Planner supports and we could work out a way to reinstate your day/week settings. CP has a bulk edit tool where you can easily update scheduling settings for hundreds of jobs at a time.
You can schedule reminder texts (for customers e.g. "cleaning your windows tomorrow") for jobs you have on a worksheet e.g. to send out at 7pm. You can text customers when payments are late directly from the debt list and I'm planning to add a "mail merge" facility here so you can text multiple customers in one go and the system will automatically insert their balance, payment ref etc. SMS integration is a Pro package feature along with GoCardless, Dropbox backup etc. The Pro is all about giving you the extra tools you need to streamline and expand your business.
