Bulk update Little Hotelier rates with an AI agent

1. Open My Apps > Front Desk > Inventory and click the orange Bulk Update button in the grid header.
2. Under When? pick the dates, under Which days? tick only the weekdays you want, and under Which room rates? select the rates that get this price.
3. Under What changes? type the new rate and click Update, then open the form again for every room rate that needs a different price.
4. Leave the greyed-out derived rates alone: Little Hotelier changes them through the base rate or the channel rate's Rate config tab in My Apps > Channel Manager > Channels.
5. Step back through the grid with the week arrows to check each price landed, because a rate below the property minimum does not save.
6. Every extra price is another pass through the form, and once a price is overwritten the grid no longer shows what it was.

Raise the Double Room rate to 140 and the Twin to 130 for every Friday and Saturday in December, and show me what each night was before.

1. 01

   Map the plan to room rates

   The agent calls list_room_rates and matches each line of your plan ("Double weekends 140") to a room rate ID. Derived rates are kept off the edit list and named in the report with the base rate they follow.

2. 02

   Snapshot the current prices

   get_inventory over the whole range gives the price of every night before anything changes. The agent keeps that snapshot as the before column, since Little Hotelier does not keep one.

3. 03

   Group nights that share a price

   Nights with the same new price, room rates and weekdays go into one update_rates call, so a plan with three prices becomes three calls. Nights already at the target price are dropped.

4. 04

   Hold back prices that look wrong

   A price below the floor you gave, or a jump bigger than you allowed, is not sent; the agent asks about it first. Little Hotelier's own minimum rate check still applies on top.

5. 05

   Approve, apply, verify

   You approve each grouped change. Afterwards the agent reads get_inventory again, compares every night with the plan and lists any night that did not save by date.

Checked in the grid: 24 of 24 nights at the new price

• Little Hotelier checks a minimum rate in three places (Front Desk Setup > Property details, Channel Manager Property settings and Direct Booking rate settings), and a rate below it does not save.
• A Little Hotelier channel rate can only be derived from its own room rate, by an amount, a percentage or both, and derived rates show greyed out in the inventory grid.
• The Little Hotelier inventory grid shows future dates only, and the Lifecycle Audit Tool tracks which settings changed but not the rate values sent to channels.
• Little Hotelier Front Desk has a fixed 716-day update period for manual bookings, while each channel receives rate updates only inside its own update period, listed under My Apps > Channel Manager > Channels.
• When a discount is set directly on Booking.com, Little Hotelier shows the discounted price the channel sends on the reservation, not the inventory rate.

update_rates asks for your OK by default. To run it on a schedule without you, switch confirmation off for that tool in your dashboard.
