Just added to the Basecamp Extras page: SimplifyThis. SimplifyThis provides an invoicing and payments solution that integrates with Basecamp. Here's how SimplifyThis and Basecamp work together:
- Allows users to invoice Projects and To-Dos.
- Extends the Basecamp data model by keeping an hourly rate for Projects and To-Dos.
- Allows users to add time entries in SimplifyThis or from SimplifyThis Google Gadget and sync them back with Basecamp.
SimplifyThis' Sanjay Kumar writes, "Unlike other applications, this integration is heavily based on simple conventions and does not require users to go through extensive setup screens. You can learn more about our Basecamp integration here."
SimplifyThis also sends out reminder letters to clients who are late with payments.
With SimplifyThis.com, not only can you track who owes you money and who is late with payments, but you can also email reminder letters. The best part is that we've done the hard work and created the letter for you, so you don't have to spend a bunch of time wondering if you are going to offend someone. It's professional and to the point -- all you need to do is send it.
The Basecamp Extras page has more tools that integrate with Basecamp for invoicing, widgets, time tracking, mobile services, etc.
