Both are free to download. Simple Invoice Maker & Receipt sells 5 in-app purchases, starting at $3.99 per month and Invoice Maker by InvoiceOwl sells 10 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Invoice Maker by InvoiceOwl holds the better App Store score, 4.4 against 4.1. That said, the two scores are not equally well evidenced: Invoice Maker by InvoiceOwl has 235 ratings behind it against 35, so its average is the more settled of the two. Written reviews complicate that: 74% of Simple Invoice Maker & Receipt's written reviews are positive against 55% of Invoice Maker by InvoiceOwl's, so the app with the better star average is not the one people write more warmly about.
