Decision summary

Six times the price, for a business six times the size.

What Contractor+ is good at

Contractor+ is enormous. A CRM, homeowner financing, a marketing site, a price book, a tool library and a punch list, aimed squarely at a contractor running crews.

The catch

Free is five invoices a month, and Pro is $49 a month, which is $588 a year. That is the right price for a business with crews and the wrong one for a person with a van.

Six times the price, for a business six times the size.

The ten rows that decide it

Two questions, and they have different answers: what you get for nothing, and what the least you can pay actually buys. Pick one.

Which one to buy

Buy Contractor+ if

  • You run crews and want the CRM, the financing and the marketing site.
  • You need card payments and accounting sync.
  • You are big enough that $588 a year is a rounding error.

Buy Invoice Koi if

  • You are one person, or two, and $588 a year is a real number.
  • You send more than five invoices a month.
  • You want invoicing that opens fast rather than a platform to learn.

What is free, and what Pro buys

The same on all eleven of these pages. One price, billed once a year, with no seat maths and no plan above it. Free is one person and their own books, counted at 100 invoices a year and at nothing else. Pro is what leaves the phone: the photographs on a server, the reading, and the paperwork a client signs or opens.

Free $0 no card, no trial clock
  • 100 invoices a year
  • Unlimited estimates and clients
  • All nine templates, reports and the jobs schedule
  • Time tracking and recurring invoices
  • Your books backed up, plus a portable backup file
Pro $99.99 a year, about $8.33 a month
  • Unlimited invoices and estimates
  • Every photograph backed up, on any phone
  • Unlimited reading, and voice notes into invoices
  • Signatures, deposits and statements
  • Priority support, in one to two working days

Everything in Free is in Pro too. Pro is sold through the App Store, so the price you are shown is your own country's.

Where these numbers come from

Every Contractor+ cell was read from their own pricing page on 7 September 2026, at US list prices in US dollars. Contractor+ is read from its published plan comparison. A blank means they do not name the feature on the page where they ask for money, and we count that as not included rather than guessing in our own favour. Processing rates appear only where the vendor is itself the processor: read a missing rate as unstated, never as free. If we have a line wrong, tell us and we will change it.

Contractor+ and every other name and logo on this page belong to their owners. They are here to say which product is being compared, which is the only reason a comparison may use them, and nothing here is endorsed by or affiliated with them.
