Car Dealer Software in Thailand: Used-Car Lot vs Franchise DMS
What Thai car dealers run their business on — สคบ. contracts, hire-purchase submissions, พ.ร.บ. and stock. Which systems fit a used-car lot and which fit a franchise dealer.
Two different products get called "car dealer software" in Thailand and they do not compete. An independent used-car lot (เต็นท์รถ) needs stock by vehicle, สคบ. contract printing, finance submissions and per-car profit — COMMACAR covers that and ships a storefront site driven from the same stock records, and BossCarSoft covers it with สคบ. printing and finance tracking but quotes on request. An authorised franchise dealer needs something structurally larger: parts, warranty and aftersales reporting up to head office, which is Dealer Vision's territory, while Suparat Motor Car System sells the pieces separately — showroom, hire-purchase and leasing, parts and service centre, and vehicle registration with พ.ร.บ. compulsory insurance. Chat and lead capture is a separate layer again; that is covered in the LINE OA guide.

The Tools in Detail
COMMACAR
Automotive · Paid · SEA · th
COMMACAR (marketed as the TENTCAR program) is a Thai used-car lot management system from Twin Software Solutions. It covers vehicle records, maintenance and reconditioning jobs, customers and referrers, income and expenses, staff payroll, a calendar, a dashboard and database backups, and it ships a customer-facing storefront website driven from the same stock data — so cars listed for sale on the lot's public page come from the inventory record rather than being posted separately. Its practical distinction in this category is commercial rather than technical: COMMACAR publishes a tiered annual price list on its own site, where every comparable Thai vendor quotes only on request.
Thai vertical software almost never publishes pricing. COMMACAR's own page previously carried an annual price list; as of 2026-08-17 all three TENTCAR tiers show สอบถาม (enquire) instead, which makes every one of the four used-car lot systems and the one franchise DMS in this category quote-only. The product still reflects how Thai used-car lots actually sell: referrers (ผู้แนะนำ) are tracked as a first-class entity alongside customers, and reconditioning work is logged against the individual vehicle, which is where the margin on a used car is won or lost.
Best for: Thai used-car lots comparing systems where every vendor quotes rather than lists; Single-lot operators whose stock sits under roughly 100 vehicles; Dealers who want a public stock page without maintaining a second website; Lots that pay referrers and need that tracked against each sale
BossCarSoft
Automotive · Paid · Free tier · SEA · th
BossCarSoft is a web-based management system for Thai used-car lots (เต็นท์รถมือสอง), built and supported from Ubon Ratchathani and Nakhon Ratchasima rather than Bangkok. It covers vehicle stock by status, bookings and sales, income and expenses, finance (ไฟแนนซ์) submissions, document storage against each car, and a CRM layer. The detail that separates it from generic inventory software is สคบ. document printing: Thailand's Office of the Consumer Protection Board mandates a specific contract format for used-vehicle sales, and BossCarSoft generates it directly from the vehicle record instead of leaving staff to fill a template by hand. The vendor states 50+ car lots across Thailand and Laos use it, and offers a free trial.
Used-car retail in Thailand runs on paperwork with no foreign equivalent. Consumer Protection Board (สคบ.) paperwork and submissions to Thai hire-purchase lenders are part of closing a deal rather than an afterthought — and vehicle hire-purchase is itself a contract-controlled business under the Contract Committee's 2565 (2022) announcement, which caps used-vehicle hire-purchase interest at 15% per year. Generic inventory or POS software handles none of it, which is why lots keep parallel Word templates. BossCarSoft generates สคบ. documents from the vehicle record and tracks finance submissions natively. It is also one of the few Thai vertical tools with declared customers in Laos, where the used-car trade is closely tied to Thai supply.
Best for: Thai used-car lots that currently track stock and สคบ. paperwork in Excel or on paper; Owners of one or two lots who want vehicle-level profit rather than a shop-level total; Dealers in upcountry Thailand who want a vendor reachable in Thai by phone and LINE; Lao used-car dealers, since the vendor already supports customers across the border
Dealer Vision
Automotive · Paid · SEA · th / en
Dealer Vision is a dealer management system (DMS) from Senior Com, a Thai software company that has been building for authorised vehicle dealers for over two decades. It runs on cloud rather than the on-premise servers the category grew up on, which the vendor positions as the cost difference against traditional dealer enterprise software, and it is usable from smartphone and tablet as well as desktop. The system spans accounts payable and receivable with invoicing and online payment, master data for products, customers, dealers and staff, pricing and discount control, user access control, and a reporting layer covering sales and revenue, inventory, finance, customers and vendors, and service performance, with a custom report builder. Notifications go out by email, phone and LINE, and the platform explicitly handles head-office-to-dealer communication — the structural requirement that separates a franchise network from an independent lot.
Thailand's franchised dealer networks have run on locally built DMS software for two decades, because a dealer's obligations to the brand — parts, warranty, aftersales reporting up to head office — are structured around the local distributor rather than the manufacturer directly. Senior Com is the incumbent in that niche and has been publicly described as a leader in the Thai DMS market; its newer DV Platform was launched in 2025 as a cloud-native successor covering sales, aftersales and parts, positioned around the shift to EVs. LINE notification is included as standard, which is the ordinary channel for reaching a Thai customer about a service booking.
Best for: Authorised franchise car dealers in Thailand running sales, aftersales and parts together; Dealer groups that need head office and branch dealers on one system; Dealers replacing on-premise DMS servers with a cloud deployment; Networks that need service-performance reporting alongside sales and inventory
Suparat Motor Car System
Automotive · Paid · SEA · th
Motor Car System (MCS) is the vehicle sales product from Suparat Computer Corp., a Thai software house that builds for the automotive trade specifically rather than adapting a general accounting package. MCS handles purchasing, payment, retail and wholesale sale, receipts, customer history, stock control and the document set a Thai dealership issues. What distinguishes Suparat in this category is coverage across the whole dealership rather than one function: separate products exist for hire-purchase and leasing finance (เช่าซื้อ ลิสซิ่ง ไฟแนนซ์), parts and the service centre (อะไหล่ และศูนย์บริการ), vehicle registration with insurance and compulsory motor insurance (ทะเบียน ประกันภัย พ.ร.บ.), short-term vehicle rental, and a web-based management report layer — alongside its own accounting package.
A Thai dealership is several businesses stacked together: it sells the vehicle, arranges the hire-purchase, registers it, sells the compulsory พ.ร.บ. motor insurance, then services it and sells the parts. Software built elsewhere treats those as separate systems, and Thai registration and พ.ร.บ. workflows have no foreign equivalent at all. Suparat covers each as its own module from one vendor, which is why it appears in dealership stacks that a used-car lot system cannot serve. Documentation and manuals are published in Thai for each module.
Best for: Thai dealerships that sell, finance, register and service vehicles under one roof; Operators who need hire-purchase and พ.ร.บ. handling rather than stock management alone; Dealers running a rental arm alongside vehicle sales; Businesses that want vehicle software and accounting from the same Thai vendor
Readyplanet R-CRM
CRM · Paid · Thailand · TH
Readyplanet R-CRM is a sales-team CRM built in Thailand by Readyplanet, covering lead and account management, sales pipeline stages, quotations and invoices, dashboards, and workflow automation. Its companion product R-Chat consolidates website chat, LINE Official Account, and Facebook Messenger conversations in one place and converts them into R-CRM leads, which is the reason it shows up in Thai high-ticket sales teams — property, insurance, and vehicle sales — where the deal is negotiated in chat but has to be tracked like a pipeline.
R-CRM is one of the few CRMs where LINE Official Account is a first-class lead source rather than a bolted-on channel, which matters in Thailand because the entire consideration phase for high-ticket purchases happens in LINE chat. Readyplanet is a Thai company selling to Thai sales teams in Thai, so the pricing is quoted in baht per year and the support runs on local hours — both things global CRMs handle badly for a 5-person showroom. The trade-off is scope: it is a Thailand-only product with no marketplace or cross-border SEA coverage, and the published packages bundle only three users, so headcount growth is a real cost line.
Best for: Thai car dealerships and showrooms tracking long, finance-dependent deals; Property and insurance sales teams that negotiate in LINE chat; Thai SMEs replacing spreadsheet pipelines with a local-language CRM; Sales managers who need visibility when reps own the customer relationship
SEA Operational Reasoning
The dividing line is not company size, it is obligation. A used-car lot owns its stock outright, sells it once, and its paperwork burden is prescribed. Thailand regulates used-car selling as a contract-controlled business: ประกาศคณะกรรมการว่าด้วยสัญญา เรื่อง ให้ธุรกิจการขายรถยนต์ใช้แล้วเป็นธุรกิจที่ควบคุมสัญญา พ.ศ. ๒๕๖๒ (Royal Gazette vol. 136, special part 164 ง, p. 21, 27 June 2019) makes used-car selling a contract-controlled business, so the sale contract must carry set particulars including ระยะทางที่ได้ใช้แล้ว, and a mileage mismatch on delivery lets the buyer rescind and recover everything within fifteen days. On top of that sits the hire-purchase submission to whichever lender the buyer uses, where used-vehicle interest is capped at 15% a year effective (2565/2022). Software for that has to know a vehicle individually — reconditioning cost, days held, referrer paid, margin on this car — because that is where the money is made or lost. A franchise dealer carries obligations to the brand instead: parts stock the distributor expects to be reported, warranty jobs, service-performance figures flowing up to head office. Those cannot be bolted onto a lot system, which is why Dealer Vision builds head-office-to-dealer communication into the platform itself. Suparat sits across both by selling separate modules, and is the only vendor in this set covering vehicle registration and พ.ร.บ. compulsory motor insurance — Thai workflows with no foreign equivalent, which is precisely why imported dealership software does not get used here. Pricing transparency in this category is poor: of the four systems reviewed, only COMMACAR publishes figures, and its own table interleaves two tier sets, so confirm which band applies before budgeting. One vendor found in search, WeCarDealer, turned out to be a parked domain and is deliberately not listed.

The questions operators actually ask.
What is the cheapest car dealer software in Thailand?
COMMACAR is the only system in this category publishing figures, with annual tiers starting at THB 3,000. Every other vendor reviewed — BossCarSoft, Dealer Vision and Suparat — quotes on request. Read COMMACAR's table carefully: it presents a THB 3,000–5,000 set and a THB 36,000–56,000 set against branch and vehicle-count limits, and the mapping is ambiguous as displayed.
Which software prints สคบ. contracts for used-car sales?
BossCarSoft generates a สคบ. contract form directly from the vehicle record, and general inventory or POS software does not -- lots running generic systems keep a parallel Word template. The reason it matters is legal, not clerical: Thailand regulates used-car selling as a contract-controlled business: ประกาศคณะกรรมการว่าด้วยสัญญา เรื่อง ให้ธุรกิจการขายรถยนต์ใช้แล้วเป็นธุรกิจที่ควบคุมสัญญา พ.ศ. ๒๕๖๒ (Royal Gazette vol. 136, special part 164 ง, p. 21, 27 June 2019) makes used-car selling a contract-controlled business, and the contract must carry specified particulars including ระยะทางที่ได้ใช้แล้ว. Deliver a car whose mileage does not match the contract and the buyer may rescind and recover everything within fifteen days. Note that the separate *labelling* announcement ฉบับที่ 35 (2556), still cited as current by most Thai sources, was repealed and replaced in 2568.
Do I need a DMS or a used-car lot system?
It depends on obligation, not size. If you are an authorised dealer reporting parts, warranty and aftersales to a brand or distributor, you need a DMS such as Dealer Vision. If you buy cars, recondition them and sell them yourself, a lot system such as COMMACAR or BossCarSoft fits and a DMS will over-serve you at a much higher price.
What handles พ.ร.บ. and vehicle registration?
Of the systems reviewed, only Suparat sells a module for vehicle registration, insurance and พ.ร.บ. compulsory motor insurance. This is one of the clearest reasons Thai dealerships run local software: registration and พ.ร.บ. workflows have no equivalent in imported dealership products.
Where does chat and lead capture fit?
It is a separate layer. None of these systems is a chat platform, and none of the LINE OA tools is a dealer management system. A dealership typically runs both — the lot or DMS for stock, paperwork and money, and a LINE OA tool such as Readyplanet R-CRM for routing showroom enquiries to a named consultant.
