The best app is the one that gets the invoice sent.
A strong invoice app removes the gap between finishing the work and asking to be paid. Compare tools on the complete workflow—not a long feature list: how quickly you can create the invoice, whether it works properly on your phone, how the client can pay, and what happens when the due date passes.

Choose for the work you actually do — A freelancer billing projects needs a different workflow from a shop running payroll. Do not pay for a full accounting ledger when invoicing and collection are the real jobs to solve.
A useful app should let you test the finished invoice before demanding a subscription, card or lengthy setup process.
Creating, sending and checking an invoice should work from a phone—not merely viewing a desktop dashboard on a smaller screen.
Look for bank transfer and local payment rails as well as cards, so a processor does not take a percentage of every invoice by default.
Open tracking, real due dates and automatic reminders matter more after the invoice is sent than another template colour.
Saved clients, reusable services and recurring invoices turn a one-off maker into a system you can keep using.
Compare the subscription, invoice limits and payment-processing costs together. The cheapest headline can still create the highest total cost.
Create a real invoice with your client, tax, payment terms and preferred payment method. If that feels slow, it will not improve when you are busy.
Confirm the PDF is clear, the client knows exactly how to pay and you can see the invoice status without maintaining a separate spreadsheet.
Include monthly fees, invoice limits and transaction fees, then choose the smallest tool that reliably covers your workflow.
Create and download the first invoice before deciding whether it fits your workflow.
