An Invoice Simple alternative with no monthly invoice limit

What Invoice Simple is good at

It's exactly what the name promises — a fast, uncluttered invoice and estimate builder with none of the bookkeeping, payroll or inventory modules that competitors bundle in whether you want them or not. For a business that wants to type up an invoice and get out, that simplicity is a real advantage.

Where it stops

• Every plan meters invoices by the month, not by client — the free tier's ceiling is low, and the paid plan's is still a fixed number rather than unlimited.
• A busy month that crosses the line means upgrading or waiting for the count to reset, whichever the invoice can afford to do.
• The plan renews every month regardless of whether that month's allowance is used.

What we do differently

BillingHub has no monthly invoice ceiling on any plan — a busy month and a quiet one cost the same per invoice, because a credit is spent per invoice issued rather than rationed by the calendar.

When to choose Invoice Simple over us

If your monthly invoice count reliably sits under their cap and you want the simplest possible app with nothing else attached, Invoice Simple is a good, honest tool built for exactly that. We add estimates and quotes that never spend anything, a recurring schedule, and an API — none of which Invoice Simple offers at any price.
