Verdict

The call

The clearest difference is review sentiment: Billdu at 89% against Invoice Maker's 43%. Billdu also leads on ads (none vs shown) and ratings volume (26K vs 12). Invoice Maker's advantage is update cadence (every 4 days vs every 2 weeks) and iOS requirement (15.0 vs 17.0). On price, in-app purchases, monetization model and device support there is nothing between them.
