How this is scored

Weighted mean of the sub-scores, weights re-normalized over whatever is computable (nobody's fixed it 25 · how far above typical 20 · how angry 15 · people in the market 15 · room to enter 15 · willingness to pay 10). Fixed anchors map each count to 0–100: breadth and willingness-to-pay are straight shares; the gap’s heat tops out at 4times the store’s typical rate; anger scores star3 as 0 and star1.5 as 100; reach runs 104 to 107ratings on a log scale; room to enter is one minus the leader’s share of shelf ratings. A factor that cannot be counted is dropped and named — never imputed. The site’s one composite (#115, owner decision 2026-08-15); cited industry benchmarks are never blended in.

“Good but they are sneaky — Good app but they make the five invoice limit very hidden so you start sending invoices then charge you way more than other apps. I’m out.”Easy Invoice Maker App · 1star · Jul 24, 2026
“Money grab — It started good until they keep going up on price for the app and now limit the amount of invoices you can send per month unless you update to a $19.99 a month plan. Unacceptable!”Invoice Maker; Invoice Simple · 2star · Jul 21, 2026
“They not tell the truth — The price in the website its a lie. They sell the $98.99 unlimited invoices when in reality its just a hook. After you purchase the Pro Plan they tell you its only 10 invoices combined with estimates and if you want the unlimited invoices have to purchase Ultra Plan which its not even in the website. They told me it only shows after you download the app. Very disappointin”Invoice Maker - Invoice Fly · 1star · Jul 17, 2026

“Terrible — You get zero support. There support people take days to respond. We paid full price for premium. And half way through the year they upped the price of premium and made us pay for even tho we paid for a year of premium up front. They did this two years in a row. To resolve the problem it, it took over a week and I was unable to bill my clients”Invoice Maker; Invoice Simple · 1star · Aug 21, 2026
“Double Billing And No Support — They were billing me twice each month and there is now way to view your billing history or to contact customer service for billing support. It was a decent app but the lack of support forced me to cancel it.”Invoice Maker - Invoice Fly · 1star · Aug 6, 2026
“Living in a cardboard box now — Easily over 50k plus in transactions, that I no longer have access to because of the sheer negligence of this company. I got sent an email request about a random audit to which I respond with all of the corresponding information, followed all the steps, and yet they terminate my account in the middle of receiving two payments, and provide no reasoning or notice.

“This app won’t save us from ourselves — Are there any good designers left in the world? I’m a first time user who spent hours crunching numbers on 2-page invoice between doing loads of laundry. Was choosing template & finishing touches when phone battery took a dump. Low battery alarm didn’t go off because I accidentally muted with slider in upper left corner of my old iPhone.

“Wolfe — What ever you do don’t buy the Invoice Simple. I’ve given them more then a month to fix an issue & it still hasn’t been fixed. They don’t have any back end support. Which means if you have a problem they have no way to fix it. I’ve had the app since 2018. Running 2 companies with it. Recently I had multiple problems with it over a several week period. I made them aware of it with over a”Invoice Maker; Invoice Simple · 1star · May 24, 2026

“Great if you have no employees — This app is fantastic until you have employees that you need to share information with. It is literally hoop after hoop to jump through to try to get somebody else signed in where they can get invoices and edit them. Verification codes that never come through. QR codes to scan. What the heck man how about just a link to click on and let somebody join”Invoice Maker - Invoice Fly · 2star · Aug 11, 2026

How this is counted

Every number is arithmetic over the reviews we hold, re-counted weekly — nothing modelled, nothing scored. Themes come from a frozen pattern classifier rather than a model reading reviews, so the same review always lands in the same bucket. A shelf rate is pooled across every app here; the store rate is the same count across 12,122 apps. A complaint is only called a gap when at least half the shelf carries it and at least 20 reviews are behind it — a problem concentrated in one app is that app’s bug.
