What stock quality control actually includes
Stock quality control has three dimensions that are managed differently and at different frequencies.
The first is the physical dimension: the mechanical and cosmetic condition of the vehicle. It is the most visible and receives the most attention, but it is not the only one. A car in perfect mechanical condition but with old photos or an outdated price has a presentation quality problem that is just as real as one with worn brakes.
The second is the documentary dimension: ensuring that the record of each vehicle in the management system has all the correct and updated information. Registration number, VIN, year, mileage, fuel, power, equipment, DGT label, available maintenance history, and origin documentation.
The third is the commercial dimension: making sure that the vehicle's publication on portals is up to date, with the correct price, the most recent photos, and the description that best reflects the actual vehicle. A car may be in perfect condition and with a complete record in the system, but if the portal ad has photos from two months ago and the price hasn't been reviewed in three weeks, it is competing at a disadvantage.
The check-in process: what to review when a new car arrives
The moment a car enters stock is the most important for quality control. What is not checked at that moment is discovered later, usually at the worst time: when there is an interested buyer or when delivery has already been committed.
The check-in review must cover four blocks. Documentation: logbook, MOT card, contract or purchase receipt with the seller's tax ID (NIF), and the complete DGT report to verify charges, liens, and previous owners. Minimum mechanical condition: brakes, tyres, lights, air conditioning, and any safety elements. Cosmetic condition: bodywork and interior damage that must be documented with photos before any prep work. And the information for the file: actual mileage, complete equipment and extras, and the MOT status with the date of the next inspection.
Check what documentation needs to be verified when buying a second-hand car.
All that information goes into the vehicle's file at the time of the review, not later. If it is written on paper or a loose sheet to be entered later, some data never makes it into the system.
Publishing checklist: what needs to be ready before uploading the ad
Publishing a car before it is ready for sale generates leads that cannot be handled correctly: the buyer calls, asks about the car, and the sales representative does not have complete information or the car is not available for viewing because it is still in the workshop. This friction damages the first impression.

Before publishing a car on the portals, there are seven elements that must be confirmed. The price set with reference to the current market for that specific model. Photos taken after preparation, with appropriate lighting and showing at least the exterior, interior, dashboard, and boot. The description written with the actual equipment, available history, and the condition of wear-and-tear components. The DGT label correctly assigned. A valid MOT or a known date for the next inspection. Origin documentation available in the file. And the car physically available for viewing without an appointment, not in the workshop or pending preparation.

If any of those seven elements is not confirmed, the car is not ready to be published.
Weekly audit of active stock
The weekly audit is not an exhaustive review of all cars: it is a quick review of the indicators that change most frequently and have the greatest impact on conversion.
The five elements to review each week are: cars that have exceeded the threshold of days without generating contacts, prices that have not been reviewed in more than two weeks, ads with photos taken before the last preparation, cars with attribute errors detected on the portals (incorrect mileage, wrong fuel, duplicated price), and cars in stock that have already been sold but are still published.

This last point causes more friction than it seems. A published car that has already been sold generates calls from interested buyers who then end up disappointed, which damages your reputation and wastes the team's time.
The weekly review takes less than 30 minutes if the management system has this information centralised. If portals have to be checked one by one to see the status of each ad, it can take hours.
Monthly audit: real stock vs stock in the system
Once a month, in addition to the quick review, a full verification must be done to ensure that physical stock matches the stock in the management system. Discrepancies between the two are more common than they seem: cars that are at an external workshop and have not been updated in the system, sold cars pending transfer that are still in active inventory, or cars that arrived without being properly registered.
The monthly audit has four checks. First, physically count the available vehicles and cross-reference them with the system's list: any discrepancy must be investigated. Second, verify that all files have the correct purchase documentation with the seller's tax ID (NIF): those that do not are a risk in the event of a REBU (second-hand goods scheme) inspection. Third, check that all vehicles sold during the month have their invoice generated and their file closed. Fourth, identify vehicles that have been in stock for more than 60 days and decide what action to take with each one.
Check what the REBU registry book must include and how to organise it.
The listing errors that reduce conversion the most
There are specific errors in portal listings that have a measurable impact on the contact rate. Not all are equally serious, but the most common ones are also the most avoidable.
An outdated price is the most costly. A price that hasn't been reviewed for weeks may be outside the competitive range without anyone detecting it, which reduces the ad's visibility in the portals' price filters.

Incorrect mileage is what generates the most distrust. If the ad says 87,000 km and the buyer arrives to see the car and the odometer reads 94,000, the sales conversation starts with an objection that is difficult to overcome.
A generic description without extras is the error that loses the most opportunities. A BMW 3 Series with a panoramic roof, leather upholstery, and parking assist described as "car in very good condition, call for more info" is not communicating the actual value of the vehicle.
Photos taken before prep work generate low-quality leads: the buyer arrives with expectations set by the dirty or poorly presented car they saw in the photos and encounters a different car, which can work in your favour but also generates viewings that do not convert.

How to assign responsibilities within the team
Stock quality control only works if there is a person responsible for each element, rather than being everyone's responsibility in general and no one's in particular.
In a small dealership with few employees, the owner or sales manager can take on most of the reviews. What matters is having a concrete checklist and a defined process, not having many people.
In dealerships with a team, the most common assignment is: the sales representative is responsible for the quality of portal ads (photos, description, updated price) because they have the most contact with leads and detect which questions are repeated. The operations or workshop manager is responsible for the physical and documentary condition of each vehicle. The owner or director does the monthly audit of real stock vs system and makes liquidation decisions.
Dealcar and digitalised stock control
Dealcar centralises the file of each vehicle with its check-in documentation, listing status, days in stock, and automatic alerts when a car exceeds defined thresholds. This eliminates the need for manual reviews of each portal separately and reduces the risk of a published car spending weeks with an attribute error without anyone noticing.

Frequently asked questions
How often should the physical condition of the cars on the lot be checked?
A weekly visual check is enough to detect obvious issues: flat battery, low tyre pressure, accumulated dirt, or damage from external elements. For cars that have been on the lot for more than 30 days, a more thorough review every two weeks helps keep them in viewing condition without requiring additional prep work at the time of the appointment.
What happens if an error is detected in the listing of a car that has already been published for weeks?
It must be corrected immediately. If the error is with the price (it was more expensive than it should have been), the correction directly benefits the ad's visibility. If the error is with mileage or equipment, the correction prevents viewings that do not convert due to a mismatch between the ad and the actual car.
How many photos are enough for a used car advertisement?
The minimum that builds enough trust for a buyer to call is between 12 and 15 photos: exterior from all four angles, front and rear, interior of the front and back seats, dashboard, boot, and details of relevant equipment. For premium cars over 20,000 euros, between 20 and 30 photos are common and expected by the buyer.
