Wave and Harvest are both popular choices for invoicing, but they solve the problem differently. Wave at $16/month costs more but tends to offer deeper functionality in its core area. Harvest at $13/month keeps costs low but relies on integrations for anything beyond basics. Both are subscriptions — meaning you pay every month whether you use them heavily that month or not.
The third option most people miss: stop subscribing entirely. Helix includes invoicing as part of a $279 one-time purchase. No monthly drain. Everything is integrated — your invoicing connects directly to your CRM, scheduling, invoicing, and time tracking. No Zapier. No copying data between apps.
SaaS tools increase prices an average of 11.4% per year — five times general inflation. Here is what that looks like for these three tools:
By year 5, Wave has cost you $926 more than Helix. Harvest has cost you $701 more. That money goes to a subscription company. With Helix, it stays in your business.
