A few tweaks after 6 months of use...

Home tab:
#1 Under the tax timetime it would be great if you still listed the entries, for example up to 7 dates, once their due date. In case you forgot to do something, you are no longer reminded once the date has passed.
#2. Under 'projects with unbilled items', it would be great if you can get rid of the ghost projects that have been completed and fully invoiced for that still get listed here.

Contacts tab:
Much cleaner now that you can have this in the grid view

#1. Archive old project names. Separate out completed/invoiced/paid for projects somehow. I'd imagine most users are only concerned with active projects on a day-to-day basis. Or have the projects with in a fixed scrollable area - one of our clients had over 70 projects against their name after 6 months - the list is getting long.
#2. Separate out your clients from your suppliers details - plus remove the 'add project button' from a supplier as that is not relevant to them.
#3. As mentioned by others that ability to multiple contacts for one client would be great.

Projects Tab:
#1. Much cleaner now that they are listed list these alphabetically via client name and that the completed jobs are now separated out for the active ones.
#2. Set hourly rate and payment terms globally (at least per client).

Project Information:
#1. It would be useful to be able to add a notes/comments field to a project.

Time Tab:
#1. Much cleaner now that it doesn't list old project names in the drop down.
#2. I like it how you have added the 'single day' feature.

Invoices:
#1. The ability to group multiple projects into one invoice (Ed - you have already told me how I can achieve this), to save you sending out multiple invoices. This can be done but it currently lists only the last project you add to the invoice as having a net £ total against it. All the other projects have £0 invoiced listed.

Eg: Project 1 = £10, Project 2 = £5 and Project 3 = £20 but under Projects>Completed projects they are listed as Project 1 = £0, Project 2 = £0 and Project 3 = £35. So at a glance you can't see the values of each project you have to open the communal invoice.

#2. Thanks for adding the ability to reorder entries, means I don't have to plan the invoice out on paper first - incase I forgot something.

#3. As others have mentioned. It would be great if you could take an invoice as an estimate, quote, pro-forma invoice, or invoice. Obviously it would only be treated as an invoice by the system when it was set to a pro-forma invoice or invoice.

My Money:
#1. The ability to have petty cash as it works in the real world - the ability to list a cash withdrawal as petty-cash. I know that at the moment you you make the purchase yourself and then make an expense claim.

Overall - we are very happy with how it works and look forward to the improvements you allude to in Get Satisfaction.

Thanks
