Verdict

The call

The clearest difference is in-app purchases: Professional Invoicing at none against Invoice Simple's 10. Professional Invoicing also leads on review sentiment (95% vs 64%) and iOS requirement (11.0 vs 16.4). Invoice Simple's advantage is ratings volume (123K vs 119) and chart position (#9 vs unranked). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Invoice Simple sells 9 in-app purchases, starting at $6.99 per month. Professional Invoicing asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Invoice Simple holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Invoice Simple has 123K ratings behind it against 119, so its average is the more settled of the two. Written reviews complicate that: 64% of Invoice Simple's written reviews are positive against 95% of Professional Invoicing's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Invoice Simple ships an update every 2 weeks, Professional Invoicing every 3 weeks. The most recent releases landed on November 6, 2026 and November 2, 2026 respectively.
