I’m really bad a making notes of things we need to invoice people for. Whilst the cricketers were at lunch I decided to write another little application to work with my Backpack account. This allows me to e-mail or update one page that contains all the things we need to invoice.

Now, I could have set aside a page in Basecamp for this purpose, but then I have to do all the adding up. Or we could keep a record for each project or client, but then I have to remember to root through all those things before I prepare invoices.

So I now have an e-mail address for a page on Backpack.

E-mails are of the format:
Client name: hours_or_money_to_invoice optional_description

e.g.:

• Fred Smith: 1.5h Update Website
• Joe Bloggs Ltd: £10 Help with Network

There’s a link on that page that updates the page body to summarise what’s due to be invoiced, all added up and sorted by client. E-mails to that page get converted into dated list items so I can check them off when invoiced.
