About Invoice Ninja
Invoice Ninja's feed is a freelancer advice blog with no trace of the software
Invoice Ninja is open-source invoicing software, but this feed carries none of it. Every entry is a freelancer advice post — raising your rates, project management tips, what clients look for, what to ask for — published monthly and truncated to a WordPress excerpt. No version, release or feature appears anywhere in the capture, and the product's actual development happens somewhere this source does not reach.
