Verdict

The call

The clearest difference is review sentiment: Quotation Book at 100% against Invoice Maker・Billing App's 56%. Quotation Book also leads on iOS requirement (12.0 vs 16.0). Invoice Maker・Billing App's advantage is rating (4.8 vs 3.0) and update cadence (every 2 weeks vs every 3 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Quotation Book sells 2 in-app purchases, starting at $1.99 per month and Invoice Maker・Billing App sells 12 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Invoice Maker・Billing App holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: Invoice Maker・Billing App has 7.3K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of Quotation Book's written reviews are positive against 56% of Invoice Maker・Billing App's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Quotation Book ships an update every 3 months, Invoice Maker・Billing App every 2 weeks. The most recent releases landed on September 30, 2026 and October 16, 2026 respectively.
