The job nobody invoices for
You know which cupboard in which flat. The one by the sea goes through coffee; the two-bedroom eats bin bags. So on a Tuesday you drive round, open three cupboards, count toilet rolls, write "loo roll, coffee, sponges" on the back of something and go to the supermarket. That hour is not in anyone's description of co-hosting, and nobody pays you for it.
The fallback is worse: a message at 21:00 saying "there is no more coffee", sent by a cleaner who has already locked the door and gone home, about a flat with a guest arriving at 15:00 tomorrow. Now it is your evening, your car and your problem.
Somebody is already standing in that cupboard
Once per stay — across Lemon's production estate the average stay is 4.8 nights — a cleaner opens that cupboard with the door unlocked and the job open on her phone. She is the only person in the chain who sees the real shelf at the right moment. Lemon's job is to make that look count.
Each property carries its own replenishment list next to its checklist and photo areas: toilet paper, bin bags, coffee, dishwasher tablets, spare sheets. At the end of the job, from the same link that holds the checklist and the camera, the cleaner reports what she used and what she finished. Nothing to install, nothing to remember: the list belongs to the property, not to her, so a backup cleaner who has never been inside reports the same items as your regular one.
What arrives on your phone instead of the drive
Lemon records each report as a transaction and takes the quantity down. When an item falls below the minimum you set, the property appears on the low-stock panel on your dashboard and you get a supply_low message on your own channel — Telegram, WhatsApp, SMS or email. In production, 15 of 20 cleaners are on Telegram, so the report usually reaches you within minutes of the clean finishing.
The timing is the whole point. The warning fires after the clean in which the last unit went, which is normally days before the next checkout, not the night before the next arrival. You buy once, when it suits you, for the flats that actually need something. And because every change is a row — cleaner's usage, your restock, a correction — "we are always short of sheets at number 4" becomes a list of dates instead of a feeling.
Six flats, as arithmetic
Lemon tracks 169 consumable items across 20 properties in production: an average of about 8.5 items a flat (arithmetic: 169 ÷ 20). Take a co-host with six flats and the estate's average stay of 4.8 nights. A busy month gives roughly 6 checkouts per flat, so about 37 across the six (arithmetic: 30 ÷ 4.8 × 6, and your own occupancy will differ).
That is around 37 counts of eight or nine items each, done by the person already in the room, in place of one cupboard-checking loop by you and however many 21:00 messages the month produces. It costs the cleaner nothing extra: the median clean is 93 minutes across 182 measured jobs, and the supplies report is part of the job, not another visit. Since February 2026, cleaners working through Lemon have filed 152 checklist reports across 533 cleaning jobs.
Setting it up takes one visit
Fifteen minutes a flat, once. List the consumables that genuinely run out at that property, put in what is on the shelf today, and set the minimum you want to be warned at — two rolls, one bag of pods, whatever gives you a comfortable week. From then on the cleaner maintains it. When a warning arrives, you restock, update the number on the Supply Stock page, and it clears.
At €14 per property per month on the 2-to-20 tier, six flats are €84. Whether one cupboard-checking drive a month is worth more than that to you is a short calculation.
What it does not do
Lemon does not order your supplies, negotiate with a wholesaler or value your inventory. It is a count, a threshold and a history, kept current by the person already standing there — with photo proof of the clean attached to the same job. The mechanics, in full, are on how supply stock tracking works.
