Check Cherry can add a per-guest charge on top of your base package price. This works for any unit type: guests, square feet, acres, letters, dozens, and more.
On the Pricing & Scheduling tab of the package, find Charge by unit? and choose one of two options:
- Yes, charge per unit — A single rate applies to every unit over a set amount and allows a set number of included units. Good for simple pricing like '$X per guest up to x number of guests.' Can include multiple tiers of various quantities at different prices.

- Yes, charge by unit range — Different rates for different tiers. Good when you want to include a base number in the package price or charge differently at higher counts.

The Unit Name dropdown controls the label your client sees through online booking, on proposals, and on the invoice.
Including a Base Number of Units
When using Yes, charge per unit, you can set a Number of units included. This tells Check Cherry how many units are already covered by the base package price. Clients are only charged for units above that number.
For example, if your package is $800 and includes 50 guests, set Number of units included to 50 and your per-unit rate to $25. A client who selects 70 guests pays $800 + (20 x $25) = $1,300. The first 50 guests cost nothing extra.
Charge by Unit Range
Most businesses want to include a base number of guests in the package price and only charge extra beyond that. The way to do this is to create a $0 tier for the included range, then add tiers above it for the additional charges.
For example, a bartending package that includes 75 guests:
| Guest Range | Price | What the Client Pays |
|---|---|---|
| 0-75 | $0 | Included in the base package price |
| 76-100 | $50 | $50 added to the booking |
| 101-125 | $75 | $75 added to the booking |
| 126-150 | $100 | $100 added to the booking |
