How we compiled this

Pricing fetched directly from each vendor's official pricing page via WebFetch on 2026-06-14. FreshBooks official page showed a 90% promotional discount active at time of fetch; the regular (pre-promo) monthly prices ($23/$43/$70) are used as the canonical figures, with the promotional prices noted. Wave annual pricing discrepancy: official page showed $190/yr while SoftwareAdvice showed $170/yr — official page used as primary. Harvest pricing shows month-to-month as the primary price with annual rates noted. QuickBooks Online pricing sourced from SoftwareAdvice (official quickbooks.intuit.com/pricing repeatedly timed out); marked as fallback. Bonsai prices are per user per month. Zoho Invoice is free with no paid tiers as of this date. Invoice Ninja annual discount calculated from published figures ($14/mo x12=$168 vs $140/yr = ~16.7% discount). All telephony fields set to null (non-telephony vertical).
