A UK car dealer in 2026 needs software for six jobs: stock and invoicing (the DMS), a website, marketplace feeds, advertising, social media and reporting. What matters most is that those tools share the same records, so you add a car once and it reaches everywhere without being typed in again. Most dealers still run several separate systems that don’t talk to each other, which means double entry, prices out of sync and time wasted.

This guide explains what each type of software does, what to look for, and how to check whether your current setup is working for you.

What counts as dealership software?

Dealership software is any tool you use to run the business, and it falls into six main categories:

Dealer Management System

Stock, purchase and sale records, valuations, vehicle history checks and reports.

Website Platform

Your dealer website, where customers browse stock, send enquiries and book test drives.

Invoicing & Accounts

Branded invoices, VAT margin scheme sums, and profit and loss reports.

Advertising

Google Vehicle Ads, PPC campaigns and retargeting that send buyers to your stock.

Marketplace Feeds

Data feeds to AutoTrader, eBay Motors, CarGurus, Motors and other listing sites.

Social Media

Posting your stock and offers to Facebook, Instagram and other channels.

The problem with using separate tools

Separate tools from separate providers mean the same car is entered several times, and the copies drift apart. A typical setup is a DMS from one company, a website from another and a social media tool from a third. That causes five problems:

  • Double entry: the car goes into the DMS, then the website admin, then each marketplace.
  • Mismatched data: prices, descriptions and photos differ from site to site.
  • Slow listings: a new car can take hours to appear everywhere.
  • Several contracts: different billing dates, support teams and logins.
  • No joined-up reporting: you can’t see which channels bring in leads and sales.

What to look for in dealership software

Judge dealership software on six things: how well the tools connect, VAT handling, the website, Google Vehicle Ads, advert writing and the contract.

1. Connected tools

Whether your tools share the same data matters more than any single feature. When your DMS, website, advertising and social media use the same stock records, a car added to stock goes onto your website, out to the marketplaces and into your social posts with no extra typing.

2. Automatic VAT sums

If you sell used cars under the margin scheme, your software should work out the VAT for you. Doing it by hand is slow and easy to get wrong. Look for invoicing that handles margin scheme and standard VAT and produces branded invoices. Our dealer invoice management guide covers what each invoice needs.

3. A website built for search

Your dealer website should be built to rank on Google from the start, not have SEO added later. That means fast pages, sound technical SEO, structured data and a design made for phones first.

4. Google Vehicle Ads

Google Vehicle Ads put your cars, with photos and prices, at the top of Google search results. Your software, or the people behind it, should handle the vehicle feed, the campaign set-up and conversion tracking.

5. AI-written adverts

Writing a fresh description for every car takes time. Good dealership software should draft descriptions for you, pick out selling points such as few owners, optional extras and service history, and write in a style that matches your dealership.

6. Flexible contracts

Many dealership software providers tie you in for 12, 24 or even 36 months. Look for 30-day rolling terms, so you can leave if the product doesn’t deliver.

How to evaluate your current setup

Five questions will tell you whether your current software is helping or holding you back:

  1. How long does a new car take to go live everywhere? If it’s more than a few minutes of work, your tools aren’t properly connected.
  2. How many times do you type in the same details? Each repeat costs time and invites mistakes.
  3. Can you see which channels bring in your leads? If not, you can’t tell where your advertising money is working.
  4. Are you tied into a long contract? If so, you have less say when things go wrong.
  5. Is your website fast on a phone? Test it with Google PageSpeed Insights. A low mobile score means slow pages, and buyers leave slow pages.

The integrated approach

Haswent was built as one platform from the start. Your DMS, website, invoicing, Google Vehicle Ads, social media automation and marketplace feeds share the same stock records and are managed from one place.

In practice, that means:

  • You add a car once, and it goes to your website and adverts from there
  • Prices, descriptions and photos stay the same everywhere
  • One team to call for your DMS, website and ads
  • 30-day rolling contracts, with no lock-in
  • AI-written vehicle descriptions in a writing style you can change

Frequently asked questions

What is dealership software?

Dealership software is the set of tools a car dealer uses to run the business: usually a dealer management system (DMS) for stock and invoicing, a website, advertising tools and feeds to the marketplaces. Some platforms, including Haswent, put all of these in one system that shares the same stock records.

What features should I look for in dealership software?

Look for stock management with data feeds, invoicing that handles the VAT margin scheme, a website built for search, adverts sent to marketplaces such as AutoTrader and CarGurus, social media posting and Google Vehicle Ads. Most important of all, the tools should share one set of records so you never type the same car in twice.

How much does dealership software cost in the UK?

It depends on how many providers you use and what each one charges. When the DMS, website and advertising come from different companies, you pay several monthly fees, and often set-up fees and long contracts as well. Haswent offers all of these on 30-day rolling terms, so compare the total you pay today with a single quote.

Can I switch dealership software without losing my data?

Usually, yes. Most providers can bring across your stock and customer records. In Haswent, you can import stock and contacts from a spreadsheet and check each row before it is saved, and cars you already have are updated rather than added twice. Ask our team about moving anything else.
