# Quotation Book vs Invoice Maker・Billing App

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.

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.

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.
