# Invoice Book vs e

The clearest difference is review sentiment: e at 97% against Invoice Book's 50%. e also leads on update cadence (every 9 days vs every 33 months) and ratings volume (144 vs 4). Invoice Book's advantage is rating (5.0 vs 4.8). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Invoice Book sells 2 in-app purchases, starting at $1.99 per month and e sells 2 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

Invoice Book holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: e has 144 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 50% of Invoice Book's written reviews are positive against 97% of e's, so the app with the better star average is not the one people write more warmly about.

Invoice Book ships an update every 33 months, e every 9 days. The most recent releases landed on September 13, 2026 and September 17, 2026 respectively.
