Deposits and chargebacks: protecting your rental agency
Pre-authorisation or a direct charge, which documents win a bank dispute, and how to answer a chargeback inside the window without improvising.
The short answer: take the security deposit as a pre-authorisation on a credit card in the driver's own name, not as a direct charge you will later have to refund, and open the evidence file on handover day, not when the dispute notice lands. A chargeback is not won by arguing with the customer's bank. It is won by sending your acquirer a package of dated documents showing what was handed over, in what condition, and what the customer accepted in writing.
You will find no deadlines and no amounts here, and that is deliberate: the window for responding is set by the card network together with your acquiring contract, and the size of the deposit is set by you, vehicle by vehicle and risk profile by risk profile. Both live in your acquiring dashboard and in your own terms and conditions. Find them before the first dispute arrives, because improvising afterwards goes badly.
- A pre-authorisation freezes funds without moving them; a direct charge moves money and makes you the party who has to give it back.
- The issuer decides on documents: with no signed contract and no dated photos, the dispute is lost before it starts.
- The response window is set by the network and your acquirer, and it runs from the notification, never from the rental date.
- Photograph the number plate, the odometer and the fuel level in the same session, at handover and at return.
- No later charge holds up if the damage policy was not accepted in writing before the keys changed hands.
Pre-authorisation or direct charge: two different exposures
A pre-authorisation, the hold you talk about at the counter, reserves the customer's funds without transferring them to your account: the money neither leaves theirs nor reaches yours, it simply sits blocked. A direct charge settles the transaction. If there turns out to be no damage, you have to refund it, and that refund is one more line on their statement that the customer may not recognise.
Why a hold exposes you less
- If you never capture the amount, the hold expires by itself and leaves no disputable transaction behind.
- You capture only what you need when damage is real: the disputed amount is smaller and easier to justify.
- Fewer lines on the statement mean fewer calls to the bank, and almost every chargeback begins with a call.
When a direct charge is unavoidable
It comes into play in two cases: when the damage is already confirmed and costed, and when the card will not carry a large enough hold. In the first, the charge goes out after you have sent the breakdown in writing, never before. In the second, the prudent call is usually not to release the vehicle at all, because a rental that starts without a real guarantee is a deferred dispute. With debit cards, how holds behave depends on the issuer and on your contract, and the window to capture can be considerably shorter than on credit; ask your acquirer how it actually works on your card terminal.
The file that wins the dispute opens on handover day
When a chargeback opens, the issuer does not ask you whether the customer was right. It asks for proof that the transaction was authorised, that the service was delivered, and that the amount matches what was agreed. All of that is created at handover and at return, and outside those two moments it can no longer be manufactured.
What to document at handover
- 1The contract signed by the driver, with the name exactly as it appears on the licence and on the card, and the cardholder identified if that is someone else.
- 2A handover report with the vehicle's condition marked and signed by the customer and by your staff member, not by one of them only.
- 3Photos with the number plate visible in the same frame as the area photographed, taken with the device's clock correctly set.
- 4The odometer and fuel-level readings photographed with the ignition on.
- 5The damage, fuel and traffic-fine policies accepted explicitly, with a signature or a ticked box, never verbally.
What to document at return
- The same photo sequence, in the same order and from the same angles: it is the comparison that convinces the issuer.
- If the car comes back out of hours, record the time your staff first reach it and photograph it then.
- Any new damage is reported in writing the same day, through the channel the customer was already using.
- If you intend to capture part of the hold, send the breakdown first and keep proof that you sent it.
Dispute type, required evidence and response window
Every dispute arrives with a reason attached, and every reason calls for a different kind of proof. Sending the wrong package is the most common way to lose a dispute that was winnable. The exact reason names vary by network, so confirm them in your dashboard.
| Dispute type | Evidence the issuer wants | Response window |
|---|---|---|
| Unrecognised charge or fraud | Signed contract, licence and ID checked against it, authentication record from the card terminal | Short window set by the network; it runs from the notification, not from the rental |
| Service not rendered | Signed handover report, dated pick-up photos, number plate of the vehicle released | Short window; the clock starts with your acquirer's notice |
| Amount differs from what was agreed | Contract showing rate and extras, accepted damage policy, breakdown sent to the customer | The same window, even while you negotiate with the customer in parallel |
| Damage or cleaning contested | Handover and return photos side by side, return report, workshop estimate | Short window; asking for the estimate after the notice almost always arrives late |
| Fuel or mileage | Dashboard photos at both moments and the accepted clause | Short window; without both readings there is nothing to send |
How to answer a chargeback without improvising
The reply is called, depending on the network, a second presentment or a representment of the transaction. In practice it is a form from your acquirer with attachments and a text field, and that field is filled in chronological order and without adjectives.
- 1Note the notification date the moment it lands: your window runs from there, and it is your acquirer who sets it.
- 2Identify the exact reason and gather only the evidence that reason asks for. Four well-chosen files carry more weight than thirty irrelevant ones.
- 3Write an account of three to five sentences: who signed, when it was handed over, what condition it came back in, and which accepted clause covers the charge.
- 4Name the files so they explain themselves: signed contract, handover report, return report, number-plate photo.
- 5Send before the window closes even if a secondary document is missing, and write to the customer without an accusing tone: many disputes are withdrawn once the cardholder understands what they are looking at.
Fewer disputes start in the booking channel
Most chargebacks a small agency sees are not born of fraud but of a badly set expectation. A customer who knows before paying what deposit will be held, what it covers and what they are exposed to if they bring the car back empty almost never calls their bank. It helps if the text they sign at the counter is text they already read when booking.
Listing the fleet somewhere the price and the deposit are visible before payment shifts part of that work to the booking itself. On DRIVO, listing costs 0 €, with no sign-up fee and no monthly fee, and commission applies only to completed bookings, so an empty week costs nothing; payouts settle automatically through Stripe and listings publish in five languages, which cuts the misunderstanding that later resurfaces as an unrecognised charge. The booking, calendar and fleet back-office lets you keep the contract, the reports and the photos hanging off each reservation, which is exactly what your acquirer asks for when a dispute arrives.
What do I do if the customer's bank rules in their favour despite all my evidence?
Ask your acquirer for the specific reason for the rejection in writing: often the evidence was good but arrived incomplete or outside the window, and that can be corrected at the next stage. If the network allows an escalation, known as pre-arbitration or arbitration, weigh whether the amount justifies the cost, because escalating is not free and an unfavourable ruling is also paid for. Once the card route is exhausted the debt does not vanish: it remains a contractual debt you can claim in writing and, where appropriate, through a civil claim for the sum owed. Then look at which document was missing and add it to your handover protocol.
Can I hold the deposit on a card that is not in the driver's name?
Your terminal will let you, but it is the scenario that generates the most fraud disputes, because the person seeing the transaction on their statement is not the person who signed the contract. If you accept it, insist the cardholder is present at handover, name them in the contract as responsible for payment with their signature, and keep a copy of their ID. If they cannot be there, the prudent choice is not to release the vehicle.
How long does a hold take to be released?
That depends on the customer's issuer, not on you. You can void the pre-authorisation on the day of return, but when the funds become available again is their bank's decision. Explain it that way at the counter and put it in writing: the complaint about a hold that is still live is one of the most common and one of the easiest to avoid.
Can traffic fines be charged against the deposit?
Only if your contract provides for it explicitly and the customer accepted it, and only by separating two things: the penalty itself, which belongs to the identified driver, and your administration costs for identifying them, which are a service of yours. Identify the driver to the DGT, the Spanish traffic authority, within the time allowed and keep the proof, because without that step the charge is hard to defend. Check with the DGT for the current identification procedure, as the channels change.
Is it worth lowering the deposit to sell more?
Lowering it raises bookings and raises exposure, and the sensible answer is not a figure but a segmentation: a higher deposit on vehicles that are expensive to repair and on new customers, a lower one on basic fleet models and repeat customers with a clean history. What should never be lowered is documentary rigour, because it costs no money and it is the only thing that turns a dispute into a dispute won.
