WaffleInvoice: iPhone, iPad, and mobile web

Best for: freelancers and service businesses that want to create, save, and send invoices from the iPhone or iPad app or a phone browser. Android access uses the mobile browser. Not for: people who require a native Android app. Offline invoice creation has not been verified for this comparison.

The Free plan includes unlimited invoice and client creation, with 25 invoice email sends per rolling 30 days. Online card and bank payments, automatic reminders, recurring invoices, and SMS are part of the $19 monthly Pro plan.

Zoho Invoice: best native app with a broad free plan

Best for: businesses that want native iPhone and Android apps, a browser version, and a free plan that includes online payments through connected gateways. Not for: businesses that need to create invoices without an internet connection or expect to exceed 500 invoices a year.

Wave: best when bookkeeping belongs beside invoicing

Best for: small businesses that want unlimited free invoices alongside bookkeeping records and optional payment processing. Not for: people who only want a lightweight invoice tool and do not need the accounting dashboard around it.

Starter users can share an invoice PDF or link outside Wave from the web or mobile app. Sending email through Wave requires a Pro subscription, accepting online payments, or using payroll. Wave also documents sharing outside Wave; payment-processing fees are separate. Its mobile-app page distinguishes the installed app from internet-required web tools, but does not confirm offline invoice creation in the native app.

Invoice Ninja: best for technical control

Best for: technical freelancers who want native apps, a client portal, payment gateways, or a self-hosted path. Not for: a business that wants the managed hosted service for more than five clients without paying for Pro.

The hosted Free plan allows five clients and unlimited invoices; hosted Pro is $14 billed monthly or $140 billed annually. The separate self-hosted version has no client limit, but you provide and maintain the server. Hosting costs are separate from the software. The self-hosting site documents operation entirely within an internal network without an internet connection; that does not establish invoice creation on a disconnected phone away from the server.

PayPal Invoicing: best for an existing PayPal workflow

Best for: sellers whose clients already prefer PayPal and who want to share an invoice by email, SMS, messaging app, social channel, or QR code. Not for: someone choosing primarily on the lowest payment-processing cost or a dedicated offline invoicing workflow.

Invoice Simple: best for low-volume native-app billing

Best for: someone who wants a straightforward iPhone or Android app and sends no more than three invoices a month on the entry plan. Not for: anyone looking for a lasting free plan or higher volume at the lowest subscription price.

Square Invoices: best for businesses already using Square

Best for: businesses that already take payments through Square and want invoices, estimates, email, SMS, and shareable links in the same system. Not for: someone who does not need Square's broader payments and point-of-sale ecosystem.
