The salesperson who never forgets to ask

Upsells offered at the moment they land.

Every stay has money left on the table: early check-in, late checkout, the mid-stay clean nobody remembered to offer. Linkbase offers it inside the conversation, prices it from your own tiers, collects through your Stripe, and then does the follow-through.

From the question to the door

Early check-in and late checkout have no inventory and no labour, so the only thing between a guest and a yes is whether the calendar allows it. Scroll to follow one sale: what exists before you set anything up, how the offer is made, how the money waits for your decision, and how the door follows.

Step 1 of 4 · Menu

Four offers exist before you set anything up

Early check-in and late checkout, priced in hours, are created for you at onboarding: one hour and two hours of each. They are applied to every active property, so the menu is live on day one. They need no inventory and no labour. The only thing that limits them is the calendar.

What's on screen

Early check-in and late checkout, in one and two hour tiers
Starter prices you can change
The same menu applied to every active property

Under the hood

One offer can carry up to twelve hour and price tiers, and can be priced as a fixed amount or per night. You widen the price ladder without creating new products.

Step 2 of 4 · Offer

It raises the offer in a conversation that was already happening

The assistant is given each booking's open offers, each with a ready-made purchase link, so it can bring up late checkout at the moment a guest asks about their morning. You are not driving traffic to an offer. You are attaching the offer to traffic you already have.

What's on screen

A guest asking what time they have to leave
The quote, in your prices
A purchase link made for this exact booking

Under the hood

The assistant can quote and link, but it has no write tools. It cannot charge a card, change a reservation or move a lock.

Step 3 of 4 · Your call

You make the call, and the card waits for it

Whether the calendar allows it is up to you, because you know your turnovers. The guest's card is authorized, not charged. When you confirm, the payment is captured. If you deny, the hold is cancelled and the guest is never charged.

What's on screen

A held payment, with nothing taken yet
Your two options: confirm or deny
Confirmed, and the money captured

Under the hood

Payments run through your own connected Stripe account. The perk is not handed over against a hold that has not been captured.

Step 4 of 4 · Door

The sale changes the door, not just the invoice

When a sale is confirmed, the access window on the smart lock moves to the new check-in or checkout time. Most upsell tools stop at taking the money. This one closes the loop, so the guest does not have to contact you and you do not have to remember.

What's on screen

A held payment leaves the lock unchanged
Confirmation moves the access window
Eleven becomes one

Under the hood

Access times are read from confirmed sales only. A payment that is still on hold never moves the lock.

Under the hood

How it actually works

1
You build the menu once
Early check-in and late checkout with hourly tiers: two hours at one price, three at another. Add-ons carry quantities and categories. Set it per property and leave it.
2
It offers, rather than waits to be asked
When a guest asks about arriving early or staying later, the AI quotes your exact options and prices in the reply. No generic “check with the host” that kills the sale.
3
Approval stays yours where you want it
Paid upgrades can require your sign-off before anything is charged. Requests that already fit your policy can go straight through.
4
Payment and fulfilment are one chain
The guest pays through your own Stripe account in the conversation or the guest portal. Once it clears, the reservation updates and the smart-lock window moves with it. Nothing left on your list.
