Invoice Ninja is capable and open-source, free if you self-host, or $14 a month hosted. But reconciliation is Enterprise-only, e-signatures are Pro and up, and there is no scheduler. Billbooks bundles the workflow, flat.
Start FREE TrialInvoice Ninja is a capable open-source invoicing tool, free if you self-host, or $14 a month hosted. The catch is where features live: bank reconciliation is Enterprise-only, e-signatures are Pro and up, and there is no scheduler or quote follow-ups at all. Billbooks bundles the workflow at a flat $7.95, with nothing to self-host.

The workflow at one price
Reconciliation, e-signatures, reminders, and a scheduler come on the Basic plan, where Invoice Ninja spreads them across Pro and Enterprise or leaves them out.
Cheaper hosted, nothing to run
$7.95 a month hosted, versus $14 for Invoice Ninja Pro, or running and patching your own server for the free self-hosted option.
Scheduler and quote follow-ups
A native booking scheduler and automatic follow-ups on quotes, neither of which Invoice Ninja offers.
To be straight with you: Invoice Ninja is open-source, so you can self-host it for free with full data ownership and unlimited everything, which a paid tool cannot match for the do-it-yourself, privacy-minded crowd. It also has a broad feature set, expenses, purchase orders, projects, and time tracking. Billbooks is for people who want the invoicing workflow bundled at one flat hosted price, with nothing to run.
Reconciliation, reminders, e-sign, and scheduler, all on one plan.
A plan built for high-volume transactions or business models that do not fit the mold.
