Dosing Consumables: The Method That Prevents Running Out

Restocking is the most time-consuming part of running a short-term rental, and the least well-equipped. Most hosts go by feel: you look in the cupboard, you guess, you buy too much or not enough, and one day the cleaner calls because there’s no toilet paper left on a Sunday. This guide gives you a sizing method that works without a spreadsheet, whether you have one property or fifteen.

The principle: calculate per night, stock per capacity

Two concepts not to be confused.

Consumption is calculated per guest per night. This is the only unit that remains valid when the length of stays changes. A four-person property with twenty guest nights will use roughly the same amount in two one-week stays as in seven two-night stays, except for “per stay” consumables.

The quantity placed in the property is set to the maximum capacity. The cleaner never has to calculate, always puts out the same amount, and you’re not relying on a number of guests that’s often inaccurate.

These two logics work together: the first is for purchasing, the second for execution.

The three types of consumables

They behave differently and need to be stocked differently.

It’s the third type that causes problems, because you don’t see it coming: the toilet block every 2 weeks, the diffuser every 2 months, the extractor filter every 6 to 12 months. These deadlines must be managed by a system, never by someone’s memory.

The alert threshold rather than inventory

Counting the entire stock at every visit is unrealistic. The alert threshold is the only practice that works long-term: for each item, you define a minimum quantity expressed in number of stays, and you only check that.

The basic rule: a minimum equal to two stays’ worth of use, which gives you time to order and be delivered without ever running out.

In practice, the cleaner doesn’t estimate anything: they simply report when they go below the marker, for example a line drawn in the cupboard or a dedicated box. A binary signal, yes or no, is infinitely more reliable than asking someone to estimate a number when they have a clean to finish.

The buffer stock, in the property

A central stock at the manager’s place is useless if the cleaner is on site at 11am and discovers something is missing. Plan for a buffer stock in each property, sized for two stays, in a locked cupboard if necessary.

This stock contains the critical consumables, the ones whose absence is a blocker: toilet paper, bin bags, dishwasher tablets, sponges, washing-up liquid. The rest can be kept in a central stock.

Two classic mistakes: stock that’s too big, which ties up cash and goes out of date, and stock accessible to guests, which disappears much faster than expected. A locked cupboard isn’t about mistrust, it’s about proper sizing.

The cleaner’s kit

Don’t confuse the property’s consumables, meant for guests, with the cleaner’s kit, which goes home with them. Mixing them up means you’ll see microfibres and gloves vanish with every stay.

A typical kit, to be restocked like everything else:

These tasks are on the checklist like any other, because a cleaner who arrives without product can’t do the clean as planned.

Calculating your consumables budget

Do the calculation in three steps, once, then it updates itself:

1. List the itemsAnd their type (night, stay, period).
2. MultiplyBy your monthly volume: guest nights for the first type, number of stays for the second, deadlines for the third.
3. Work it out per guest nightThe only figure you can compare between properties.

This cost per guest night is what you should track, not the raw monthly spend: it immediately shows up any drift, for example a property where dispensers empty twice as fast as elsewhere, which usually means a leak or a badly adjusted pump.

Tracking that survives a change of cleaner

Three pieces of information must live at property level, never in someone’s head: the list of consumables with their reference quantity, the alert threshold for each, and the date of scheduled tasks (toilet block, diffuser, filters). A replacement who takes over a property at short notice should be able to do exactly the same visit without calling anyone.
