One link picks the dates, signs the contract, takes the deposit
Hardbook
You agreed the dates. Then the client went quiet before signing, and the job was gone. Hardbook is one link that closes that gap.
Your client picks the dates and signs, all in one link
Your client picks the dates and signs, all in one link.
You paste one link into an email. Your client opens it in any browser, no account, picks the dates, signs the contract, and puts a deposit down, all in one pass. The booking lands on your calendar locked, not just agreed.
Your calendar and your contract don't talk to each other
Your calendar and your contract don't talk to each other.
You already own a calendar and a contract. They just live in separate tools. A scheduler like Calendly books the slot. An e-signature tool like DocuSign signs the paper. Neither holds the deal in between, so the date sits agreed but unsigned, where it can still slip. Hardbook guards that single handoff. One job, not a CRM.
The signature is what locks the calendar
The signature is what locks the calendar.
You'd think this is just those three tools stapled together. But here, the signature itself moves the calendar. A date is either pencilled in, agreed out loud and able to vanish, or hard booked, signed and locked. The moment your client signs, a maybe becomes a booking. And since only a signature holds a day, if two clients want the same date, the first to sign keeps it. Hardbook even picks the contract itself, a full agreement for a new client, a short work order for a repeat one, then fills it in so the number they sign is the number you keep.
It turns writing the contract into an arcade game
It turns writing the contract into an arcade game.
The part everyone dreads is writing the contract. Hardbook turns it into an arcade game, with a scoreboard and a slot for every piece of the deal. The scariest job on your plate, and it's genuinely fun.
Free to lock a signed date. Pro to take the deposit
Free to lock a signed date. Pro to take the deposit.
There's a real free tier that locks a signed date at no cost. The catch: taking a deposit at signing is the Pro plan, nineteen dollars a month. Your client never pays, and Hardbook takes no cut. Built solo by Adam, the founder.

So the date that used to slip now locks the moment your client signs. The all-in-one suites already bundle all of this. Does guarding just this one handoff win?
