Asking your B&B guests for a deposit: when, how much and how to handle it correctly

A guest checks out, and only a day later you spot the wine stain on the mattress or the cracked glass of the shower door. Without a deposit you're left empty-handed: the guest is gone, the OTA payout is already on its way, and an argument after the fact is one you rarely win. A security deposit is your insurance against exactly that scenario. But it's also a hurdle: ask for too much or in the wrong way, and the guest drops out before they even book. This article sets out when a deposit makes sense, what amount is reasonable, the crucial difference between a pre-authorisation and an actual charge, and how to get it cleanly sorted across all your channels.

When a deposit really makes sense

Not every B&B needs a deposit. For a classic room with breakfast, where you see the guest yourself at arrival and departure, the risk is small and the deposit often more hassle than it's worth. A deposit only starts to pay off once one of these applies:

• Self-check-in with no personal contact. If you work with a smart lock or key box, you don't see the guest. A deposit replaces part of that lost oversight.
• A whole holiday home. An entire house with a kitchen, appliances and furniture carries a different risk than one room. Here a deposit is the rule rather than the exception.
• Groups, stag weekends, events. Exactly the bookings where damage and disturbance statistically happen more often.
• Valuable interiors. A designer sofa, a fireplace, in-room wellness: the higher the replacement value, the more sense a deposit makes.

For an ordinary B&B room you're often better off asking for no deposit and instead putting one clear sentence about damage in your house rules. Every extra step in the booking process costs you conversion.

How much is reasonable?

The rule is simple: the deposit covers realistic damage, not the value of your entire property. A deposit higher than the room rate feels like distrust to the guest and drives them away.

• A single B&B room: €50 to €150, if you ask for one at all.
• Holiday home: €200 to €500, depending on size and interior.
• Groups or party venues: higher is fine, but be explicit about why.

More important than the exact amount is that it's clear up front. A deposit that only comes up at arrival is the fastest route to a bad review — especially for a guest who has already paid and feels ambushed.

The difference most operators don't know: pre-authorisation versus charge

This is the heart of a good deposit, and where it often goes wrong in practice.

A pre-authorisation reserves the amount on the guest's credit card without actually charging it. The money is blocked, but never leaves the guest's account. If there's no damage, the reservation simply lapses — usually within a few days. The guest never pays a cent; you still have your safety net. This is almost always the right choice. It feels lighter, involves no refund hassle, and shows trust.

An actual charge does take the money, and you refund it after a damage-free stay. Sounds similar, but it's a worse idea: you're holding someone else's money, the guest is waiting for their refund, and every day of delay is a potential conflict. Only do this if a pre-authorisation isn't technically possible.

The rule of thumb: block, don't charge. And communicate it the same way: "we'll block €150 on your card, released automatically after your stay" sounds very different from "we'll withhold €150".

Where it goes wrong: every channel does it differently

Deposits are notorious because every booking channel has its own mechanism for them — and you're the one who has to make them all line up.

• Booking.com lets you set a deposit policy the guest sees at booking, but collection usually happens outside Booking — via your own payment terminal or a pre-authorisation on the card.
• Airbnb runs its own deposit system: you state an amount, but Airbnb decides on any claim through their process. So you don't ask for a deposit outside Airbnb here.
• Your own booking widget is the one place where you have full control: here you decide whether, when and how you block a deposit.

The pitfall is a deposit you ask for on your own site but forget to mention on the OTA — or the other way round. The guest who booked on Booking.com and suddenly has to leave a deposit on arrival that appeared nowhere is right to complain. Make sure your deposit policy says the same thing on every channel, in the right language and with the right amount.

How to handle it in practice

1. Decide whether you need a deposit at all. Classic room with a personal welcome: probably not. Self-check-in or a whole home: probably yes.
2. Choose a reasonable amount that covers realistic damage, not your entire contents.
3. Use a pre-authorisation, not a charge. Block, don't debit.
4. State it before booking, on every channel, in plain language.
5. Release it fast after a damage-free stay — and let the guest know it's done.

That last step is often forgotten and is free goodwill: a quick "your deposit has been released, thanks for visiting" is exactly the kind of touch that turns a guest into a repeat booking.

Where BedFlow PMS makes the difference

In BedFlow PMS you attach a deposit policy to the room or home where it's needed, and not to the rest. On a direct booking through your commission-free widget the deposit is handled as a separate line, apart from the accommodation price — so your invoicing and your figures stay clean and you don't accidentally book a pre-authorisation as revenue.

Because your room attributes and conditions flow two-way to Booking.com, Airbnb and Expedia, the same deposit policy sits everywhere, in the guest's language — you change it once instead of across four extranets. And because the deposit is clearly visible next to the booking, you know at departure exactly what still needs releasing. That's precisely where a deposit belongs: a quiet insurance the guest barely feels, and that still protects you.

In short

• A deposit mostly pays off with self-check-in, whole homes and groups — not on every classic B&B room.
• Keep the amount reasonable: it covers damage, not the value of your property.
• Use a pre-authorisation (block) rather than an actual charge (debit).
• State your deposit policy before booking and make sure it says the same on every channel.
• Release the deposit fast and tell the guest — it costs nothing and earns goodwill.
