# TeamCERTin vs Invoice Maker +ㅤ

The clearest difference is monetization model: TeamCERTin at free against Invoice Maker +ㅤ's subscription. TeamCERTin also leads on ads (none vs shown) and review sentiment (100% vs 87%). Invoice Maker +ㅤ's advantage is ratings volume (83 vs 2). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. TeamCERTin sells 10 one-off in-app purchases and Invoice Maker +ㅤ sells 4 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

TeamCERTin holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Invoice Maker +ㅤ has 83 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 100% of TeamCERTin's written reviews are positive against 87% of Invoice Maker +ㅤ's.

TeamCERTin ships an update every 3 weeks, Invoice Maker +ㅤ every 2 weeks. Both last shipped on November 3, 2026.
