# Billdu vs Invoice Maker

The clearest difference is ads: Billdu at none against Invoice Maker's shown. Billdu also leads on update cadence (every 2 weeks vs every 9 months) and ratings volume (26K vs 4). Invoice Maker's advantage is monetization model (ad-supported vs free with in-app purchases). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. Billdu sells 10 in-app purchases, starting at $7.99 per month and Invoice Maker sells 2 in-app purchases, starting at $24.99 per year. Whichever you choose, the download price is not the number that matters.

Invoice Maker holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Billdu has 26K ratings behind it against 4, so its average is the more settled of the two.

Billdu ships an update every 2 weeks, Invoice Maker every 9 months. The most recent releases landed on November 12, 2026 and October 30, 2026 respectively.
