SimplyInvoices is a new app which lets you invoice your Basecamp time quickly and easily. Here’s a brief run down of how it works: you begin by creating a template with all the relevant details, e.g. client name and address, once that’s set, input your start and end dates; from there you can preview and edit your invoice, making any changes to the data imported from Basecamp if necessary; finally, download the PDF to send to your clients. You can review and edit invoices from your dashboard. Pricing is tiered. Users may create up to 5 templates for free. For $9 a month you can create 10 templates; $25 a month gives you an unlimited number of templates.
