I built Inka because every invoice app I tried was ugly, overcomplicated, or charging upwards of £100–200 a year for something that should be simple. Inka lets you create a professional invoice in under 60 seconds. 3 beautiful PDF templates, full client management, works fully offline - no account ever needed. Monthly or yearly plans, or pay once with the lifetime option and own it forever. No subscription trap. Try free for 7 days. No mid-year price hikes!
