Dealership DMS Conversion Timeline
Signature to a clean month end close is usually four to six months. Here is where the time actually goes, and which weeks hurt.
Set the expectation before you set the date
Start with the honest range, because the number in the proposal and the number your controller lives through are rarely the same. Most single rooftop conversions take four to six months from signature to a month end close that nobody had to reopen. Multi rooftop groups, multi franchise points and stores with heavy fixed operations volume run longer, sometimes eight or nine months, and that is not a sign anything has gone wrong.
Two things stretch the schedule more than any others. The first is data condition, which is almost never as good as the store believes. The second is staff availability, because the people who have to do the work are the same people running the business, and there is no week in a dealership where nobody is busy.
Be clear about what we are and are not. LeadLocate does not sell a dealer management system. There is no general ledger, no accounts payable, no payroll, no deal posting to accounting, no parts, no repair orders, no title or registration work. This page exists because dealers ask the question and most of the material available comes from vendors with an interest in the answer. What we do sell sits alongside whatever system you choose, which is covered at the end.
The phases, at a glance
| Phase | Typical duration | Who carries it |
|---|---|---|
| Evaluation and contract | 6 to 12 weeks | Dealer principal, GM, controller |
| Discovery and data extraction | 4 to 8 weeks | Controller, office manager, vendor |
| Configuration and account mapping | 4 to 8 weeks | Controller and department heads |
| Data validation and test loads | 2 to 4 weeks, overlapping | Office and department leads |
| Training | 2 to 4 weeks | Every department |
| Cutover | One weekend, usually month end | Everyone |
| Stabilization to first clean close | 30 to 60 days | Controller above all |
These overlap in practice. Configuration and validation run at the same time, and training starts before configuration is finished because waiting for a perfect system before training anyone is how conversions slip a month.
Evaluation and contract, six to twelve weeks
This is the phase stores rush and later regret. The demos take a few weeks. What takes the rest is due diligence: reference calls to stores your size on your franchises, a written scope of what conversion services are included, and the answers to the questions that only matter later.
The three to nail before signature. What exactly will be converted, in what depth, and what will not. What the total cost is including conversion services, training, hardware, third party integrations and the first year of support, not just the monthly. And what happens to your data if you leave, in what format, at what cost, on what notice.
That last one is the one people skip and it is the one that decides how your next conversion goes. Ask it while you still have leverage, which is the moment before you sign rather than the day you give notice. It is worked through in detail on dealership DMS data ownership, and the wider evaluation sequence is on switching dealer management systems.
Do not sign a start date that lands your cutover in your two busiest months. December and the end of your model year are bad choices for reasons that have nothing to do with software.
Discovery and data extraction, four to eight weeks
Here is where the schedule usually first slips, and the cause is almost always the same: the data is worse than anyone expected.
Extraction sounds mechanical and is not. Your outgoing vendor has to produce files, and the depth of what they will produce varies enormously. Customer records and open accounting balances are usually straightforward. Full transaction history, repair order detail, parts history, technician time records and closed deal jackets are where the arguments start, and some of it may only come out as reports rather than as structured data you can load anywhere.
Meanwhile the store discovers its own condition. Duplicate customers, three spellings of the same fleet account, vehicles attached to the wrong owner, inactive employee records still holding open items. All of that has to be cleaned before it moves or it becomes somebody else's problem inside a system where it is harder to fix.
Clean it in the old system where your people already know the screens. The sequence is laid out on data cleanup before migration, and what a conversion service should and should not be doing for you is on DMS data migration services.
Configuration and account mapping, four to eight weeks
This is the controller's phase and it cannot be delegated to the vendor, however much the vendor offers.
Chart of accounts mapping, factory statement setup, expense and sales account structure, department codes, pay plans, tax tables and defaults for every workflow that will run daily for the next decade. Every shortcut taken here shows up in a report six months later that does not tie, and by then nobody remembers which decision caused it.
Department heads have to be in the room for their own areas. Service defaults set by an accountant will not survive first contact with a service drive, and parts pricing rules configured by someone who has never run a counter will be wrong in ways that cost money quietly.
Budget real hours for this rather than fitting it around a normal week. Stores that succeed here typically pull the controller partly off day to day work for a month, or bring in temporary help for the routine so the expertise goes where it matters. That cost belongs in your budget from the start, and it is one of the items covered on the hidden costs of switching.
Validation, test loads and training
Insist on at least one full test load before the real one, and validate it against numbers you already trust rather than against the vendor's own summary screen.
Check the things that will embarrass you in front of a customer or a factory rep. Do open accounting balances tie to your current trial balance. Does inventory match unit for unit, including units in transit and wholesale pending. Do customer counts reconcile. Do open repair orders and open parts orders carry across with their detail intact. Does anything sort strangely, which usually means a field was mapped to the wrong place.
Training overlaps this and should start before configuration is finished. Two to four weeks, department by department, with people learning the workflows they will actually use rather than sitting through a general overview. Identify a super user per department during training rather than after, because on cutover Monday your staff will ask the person next to them before they call a support line. Structuring that is covered on the employee training plan.
Expect resistance from long tenured staff and treat it as information. The person who has run your parts counter for twenty years usually objects for a reason worth hearing.
Cutover weekend and the first two weeks
Cutover is almost always a month end weekend, because the accounting cutoff is cleanest there. The sequence is: close the old month, freeze entry, run the final extraction, load, validate, and open Monday on the new system.
Staff the Monday and Tuesday heavily. Everyone in early, the vendor on site or on a dedicated line, and managers on the floor rather than in an office. Expect throughput to drop for a week or two and plan around it rather than pretending it will not happen. Do not book your biggest sale event for the week after go live, however tempting the calendar looks.
Keep a running issue log with an owner and a priority on every item, and triage it daily for the first two weeks. Issues that get reported verbally and never written down are the ones still unresolved in month three.
Some stores run a short parallel period on parts of the operation rather than a hard cutover. It is more work and it buys real safety in specific areas. The tradeoffs are on parallel run conversion, and the day of sequence is on the cutover checklist.
Stabilization and the first month end close
The conversion is not finished at go live. It is finished when your controller closes a month without reopening it, and that is usually the second close rather than the first.
The first close after a conversion is the hardest day of the whole project. Accounts that were mapped optimistically reveal themselves. Schedules that looked clean have items nobody can identify. The factory statement needs rework. Plan for the controller to have almost no availability for anything else that week, and do not schedule any other change on top of it.
Thirty to sixty days after go live, run a deliberate review: which reports are still wrong, which workflows people have quietly worked around, which training gaps are showing. Workarounds harden into permanent habits within about ninety days, so this review has a real deadline even though nothing forces it.
The department by department checklists are worth handing out here rather than keeping in a project folder. There are separate ones for sales, service and controllers.
Keep the sales and lead layer out of the blast radius
One piece of planning advice that saves stores more than any scheduling trick: do not change your customer facing sales systems in the same window as your accounting systems.
A conversion consumes management attention for months. If your CRM, your lead sources and your phone handling are also in motion, nobody can tell which problem came from where, and the sales side is where your revenue actually is. Freeze it, or better, make sure it is stable and independent before the conversion starts.
That independence is worth checking. LeadLocate runs without a DMS integration and without an inventory feed. Neither is required, which is deliberate, and it means your lead handling, texting, calling, follow up processes, desking and reporting keep working normally while the back office is mid conversion. If you do have a feed, Inventory Link can ingest it and advertise your actual vehicles, and that can be connected after the dust settles rather than during.
We do not sell a dealer management system and will not pretend the conversion is our expertise to run. What we can do is keep the front of the store steady while you do it, on month to month pricing with no long term contract. Figures are on the pricing page, and contact us if you want to talk through the sequencing before you sign anything.
Frequently Asked Questions
How long does a DMS conversion take?
Four to six months from signature to a clean month end close for a single rooftop. Groups, multi franchise points and stores with heavy fixed operations volume commonly run eight or nine months. Data condition and staff availability drive the variance.
When is the best time of year to convert?
A month end in one of your slower months, well away from your busiest selling season and away from year end. Avoid scheduling any other major change in the same quarter, especially anything customer facing.
What slips the schedule most often?
Data condition. Duplicate customers, mismatched vehicle ownership and history the outgoing vendor will only produce as reports rather than structured files. Cleaning data in the old system before extraction is the single most effective schedule protection.
How long until things feel normal after go live?
Throughput dips for one to two weeks and the first month end close is the hardest day of the project. Most stores describe the second close as the point it feels routine, which is thirty to sixty days after cutover.
Does LeadLocate sell a dealer management system?
No. There is no general ledger, accounts payable or receivable, payroll, deal posting, parts, repair orders, or title and registration work. We sell the lead generation, CRM, communication and desking layer that runs alongside whichever system you pick.
Should we change CRM at the same time?
No. Change one thing. A conversion already consumes months of management attention, and moving the customer facing systems at the same time makes every problem impossible to attribute. Stabilize the sales side first or leave it alone entirely.
Keep the sales floor steady while the back office changes
Leads, texting, calling, follow up and desking that run without a DMS integration, so your conversion does not take the front of the store with it.
