Verdict
The clearest difference is in-app purchases: COMAX Service at none against Invoice Maker's 3. COMAX Service also leads on ads (none vs shown) and iOS requirement (11.0 vs 13.0). Invoice Maker's advantage is update cadence (every 5 days vs every 5 months). On price and device support there is nothing between them.
