### 3. How to choose in 3 steps

1. **Decide if you need full accounting or just invoicing.**

- If you just want to send invoices and get paid with minimal complexity, **Invoice Simple, Wave, Square Invoices, Invoice Ninja, or Invoicely** can all work.[1][3][4][6][7]

- If you also need bookkeeping, bank reconciliation, profit & loss, and tax reports, **QuickBooks Online** or **Wave** are better fits.[2][4][5]

2. **Match the tool to how your customers pay you.**

- Lots of in‑person card payments → **Square Invoices** integrates directly with Square’s payment ecosystem.[3]

- Mostly online / remote clients → **Wave, Invoice Simple, Invoice Ninja, Invoicely, or QuickBooks** all support online payments.[1][2][4][6][7]

3. **Balance price vs. room to grow.**

- Start free (Wave, Square Invoices basic, Invoice Ninja free, Invoicely free) if cash is tight.[3][4][5][6][7]

- If you expect to hire staff, need payroll, or complex reporting, starting on **QuickBooks** can save a migration later.[2][4]
