The verdict in three sentences
An independent multi-brand dealership in Miami that runs vehicle sales, service and the parts counter on three separate tools loses cash in slow-moving inventory and revenue in poorly tracked repair orders. A major dealer management system typically costs 25,000 to 65,000 USD a year (often tied to a franchise agreement), while a Kolonell custom tool costs 10,670 to 22,870 EUR (about 11,700 to 25,200 USD), with a 4 to 6 month timeline. The first metric to target is a parts turn of 4 to 6 a year, which alone frees up a significant amount of working capital.
The hidden cost of three separate tools
In Miami-Dade, from Doral to Hialeah, an independent dealership sells new and pre-owned vehicles, services fleets (logistics, rental, construction) and buys parts from distributors and OEM channels. When salespeople, the service manager and the parts counter do not share one database, errors pile up.
| Indicator (2026 order of magnitude) | Common situation | Target with a unified tool |
|---|---|---|
| Parts inventory turn | 2 to 3 a year | 4 to 6 a year |
| Parts obsolete over 12 months | 20 to 35 % of stock | Under 10 % |
| Service bay utilization | 50 to 65 % | 70 to 80 % |
| Repair orders invoiced late | 10 to 20 % | Under 3 % |
| Unbilled technician hours | 8 to 15 % | Under 5 % |
| Post-sale service reminders | Rare, manual | Automated by SMS and email |
| Lead time on back-ordered parts | 1 to 4 weeks | Unchanged, but anticipated |
Parts inventory is the costliest line: with 300,000 USD in stock, every turn gained frees up tens of thousands in cash.
Enterprise DMS or custom tool
A major DMS offers direct OEM catalog and warranty integration. For an independent multi-brand dealer, it is often oversized and expensive, with long contracts and per-user fees.
| Criterion | Enterprise DMS | Kolonell custom tool |
|---|---|---|
| Upfront cost | 5,000 to 20,000 USD setup | 10,670 to 22,870 EUR (about 11,700 to 25,200 USD) |
| Recurring fees | 25,000 to 65,000 USD a year | No licence, maintenance about 50 to 180 EUR a month |
| Multi-brand | Strong for franchise brands | All your brands and pre-owned |
| OEM parts catalog | Native | Price file imports, links to catalogs |
| Payments | Cards, ACH | Cards, ACH, financing partners, Zelle reconciliation |
| Fleet accounts | Standard | Fleet contracts, purchase orders, monthly billing |
| Contract length | Often 3 to 5 years | None, you own the code |
A hybrid setup is common: keep OEM portals for warranty and genuine parts orders, and run the whole business in the custom tool.
Modules to plan for
| Module | Functions | Indicator |
|---|---|---|
| Vehicle sales | New and used inventory, trade-ins, deals, finance files | Average days to sell |
| Repair orders | Write-up, inspection, estimate, technician time, photos, invoicing | Billed vs clocked hours |
| Parts inventory | Receipts, issues per RO, reorder points, cycle counts | Turn and obsolescence |
| Service CRM | History per VIN, service reminders, satisfaction | Customer retention rate |
| Fleet accounts | Contracts, vehicles per client, maintenance schedule, monthly invoice | Fleet revenue per client |
| Management | Margin by department, WIP, receivables | Monthly leadership decisions |
The fleet module is often the most profitable: a well-managed 40-vehicle contract means recurring, predictable service revenue.

FAQ
How much does a custom dealership management system cost?
At Kolonell, a tool covering sales, service, parts and after-sales falls into our complex application range, 10,670 to 22,870 EUR (7 to 15 M FCFA). Price depends on the number of rooftops, brands and integrations with OEM portals.
Can it replace a franchise-mandated DMS?
Not always: some OEMs require their certified DMS for warranty claims. In that case, the custom tool runs the rest of the business and exchanges data with the DMS by export or API, with no double entry on repair orders.
Does it handle Florida sales tax?
Yes, invoices apply the 6 % Florida state rate plus the Miami-Dade discretionary surtax of 1 %, and produce the reports you need for filings.
How long does the project take?
Plan 4 to 6 months: 3 weeks of scoping, a first service and parts release around month three, then sales, CRM and fleet.
Can we keep our accounting software?
Yes, invoices, payments and inventory valuation are exported to your accounting package daily, which avoids 10 to 20 hours of reconciliation a month.
