WHY KALSO EXISTS

Harvest tried to put me on a $1,900-a-month plan.

I used Harvest for years. When I went to add my third teammate, they quietly defaulted me onto the Unlimited plan — $1,900 a month on top of my seats. I caught it before they charged me.

So I switched to their “Flex” tier. Eleven dollars a seat, plus surcharges every time my team crossed an invisible line: $25 here for an extra task, $60 there for an eleventh project, $110 when invoicing tipped over $20K in a month. A three-person team paying $178 a month for a tool that hasn't shipped a real AI feature in 2026.

The same team on Kalso costs $21 a month. No tiers. No surcharges. No “Unlimited” trapdoor. Seven dollars a seat, locked in for life if you sign up as an early customer.

I built Kalso because I wanted Harvest to be Kalso.

Harvest is the more mature product — more integrations, more years in market, native mobile. But they defaulted me onto their $1,900-a-month Unlimited planwhen I added my third teammate, and even after I switched to their cheaper “Flex” tier I was paying $178/month for three people. The same team on Kalso costs $21. If your business is growing and you don't want to pay more every time you sign a new client, try kalso.

WHAT TEAMS ARE TELLING US

Built with — and for — agencies that bill the hour.

Harvest was costing us about $290 a month for twelve seats once you counted the surcharges. Kalso is $84, flat. The AI parsing alone deleted Fridays — nobody at Northbound writes a timesheet anymore, they just describe their week.

The profitability view caught a retainer that had been quietly underwater for two quarters. We renegotiated the rate the next week. It paid for the next decade of Kalso seats.

Devon Park

Invoicing used to take an hour every Friday. Now it's 'review the AI-drafted entries, click invoice, done.' I get my evenings back and clients get their bills faster.

I emailed Jake at 11pm with a weird bug. He'd shipped a fix before I was back at my desk the next morning. I've never had that from a SaaS vendor in my life.

Ines Halverson

Harvest kept inventing line items to charge us for — an eleventh project, the twentieth invoice, whatever. $7 a seat, no asterisks, is the entire pitch and it's the entire reason we switched.
