A DMS conversion will copy your old problems faithfully unless somebody decides otherwise. The decisions that decide whether a conversion works are made long before go-live, and most of them belong to the business, not the vendor.
Changing your DMS, ERP or point of sale is one of the biggest projects an independent business takes on. It touches every department, it costs real money, and it happens on top of a full workload, not instead of one.
It’s natural to expect the new system to fix what was wrong with the old one. Sometimes it does. But a lot of what goes wrong with a system was never the system. It was how it was set up, how the data was kept, and how people were trained to use it. Bring all of that across unchanged and you’ll have the same problems on a newer screen.
First: is it the system, or the setup?
Before committing to a conversion, be sure the system is really the problem. Reports nobody trusts, inventory that never matches, margins nobody can explain: these are as often setup and habit problems as software problems.
If the system you have, properly set up, could do the job, a conversion is an expensive way to find that out. Getting More From the System You Have covers how to tell the difference, and Start With the Decision, Not the Report covers the question to ask first.
If it really is time to change, the rest of this is about getting the business side right.
What the vendor does, and what they don’t
A software vendor knows their product. They’ll install it, configure it, convert your data and train your staff on the screens. What they aren’t responsible for is your business: your policies, your decisions, your staffing, your sign-offs, and how one department depends on another.
The vendor’s side
Installing and configuring the software
Converting data in the format agreed
Training staff on how the screens work
Supporting the product after go-live
Your side
Deciding how the business should run in the new system
Cleaning and checking the data before it moves
Testing real day-to-day scenarios
Making sure each person is ready for their role
Signing off before go-live
Owners often assume the implementation includes everything in the second column. It usually doesn’t, and that gap is where conversions get into trouble.
Make the decisions before they become configuration
Every setting in a new system is a business decision in disguise. How parts are priced. How special orders are handled. Which account a deposit goes to. Who can approve a return, and up to what amount. How departments are split for reporting.
If nobody on the business side makes those decisions, someone else will: a consultant working from a template, or a staff member answering a question on a call without knowing it affects month-end. It works until it doesn’t, and by then nobody remembers why it was set up that way.
Write each decision down: what was decided, why, and who decided it. A year from now, when someone asks why the system does what it does, you’ll be glad you did.
Conversions rarely fail at go-live. They fail at a decision made three months earlier that nobody wrote down.
Clean the data before you move it
A data conversion copies what’s there. Duplicate customers, part numbers superseded years ago, on-hand quantities nobody has counted, vendors you stopped buying from: they all come across, and now they’re in the new system too.
Cleanup is slow, unglamorous work, and it’s tempting to leave it until after go-live. Don’t. After go-live there’s never time, and every report built on bad data inherits it.
Duplicate and inactive customers
Superseded and obsolete part numbers
On-hand quantities that haven’t been counted
Old vendors and out-of-date price files
Open orders, deposits and work orders that should have been closed
Account balances nobody can explain
Two of those have their own articles: getting a physical inventory you can trust, and customer deposits, which are easy to carry across wrong.
Test the business, not the buttons
Vendor testing checks that the software works. Business testing checks that your business works in the software. They aren’t the same thing.
Take real scenarios from a normal week and run them from start to finish. A special order with a deposit that gets picked up a month later. A warranty repair with parts. A return on a sale from last season. A commercial account on terms. A cycle count. Follow each one all the way through to month-end, and check that the numbers land where they should.
Anything that fails in testing is cheap to fix. The same problem found on the first busy Saturday after go-live isn’t.
Agree what ready means before the day
Go-live dates have a way of becoming fixed long before anyone knows whether the business is ready. Decide in advance what has to be true to go live: which tests have passed, who’s been trained, and what happens if something goes wrong on the day. Then stick to it.
Postponing a conversion is a legitimate outcome. Going live on a date nobody believed in is how a project that was mostly fine becomes the one everyone remembers.
Don’t skip the part after go-live
The weeks after go-live are when habits form. If people find workarounds for things that don’t work yet, the workarounds become how the business runs. If reports aren’t checked against reality, nobody trusts them, and the old spreadsheets come back.
Stabilization gets skipped more often than any other phase, because the project feels finished. It isn’t finished until the workarounds are gone, the reports have been checked, and everyone is using the system the way it was set up to be used.
The shape of a conversion
01
Operational readiness. Goals, leadership, risks and the things that have to be true first.
02
Process and data preparation. Workflows, data ownership, cleanup and a plan to check the numbers.
03
Decisions and configuration. Requirements turned into written, tested decisions, with a record of who decided what.
04
Training and testing. Real day-to-day scenarios, and each person ready for their role.
05
Cutover. A controlled switch, with go and no-go criteria agreed in advance.
06
Stabilization. Workarounds removed, reports checked, and the system used the way it was set up.
Each phase has decisions, owners, and something that has to be true before the project moves on. The vendor runs the software through all six. Somebody has to run the business side.
How this connects
Area: Administration — the financial and administrative work that turns a month of activity into numbers you can trust.
Applies across: Every area. A system change is when a lot of decisions about how the business runs get made at once.

A seasonal business makes most of its money in a few busy months, and most of the decisions that shape them are made in the slow ones. Preseason planning is where the season is won.
Warranty Claims Are Money You’re Owed
Warranty work is done, the customer leaves happy, and the claim gets filed late, short or never. Treat warranty claims as receivables and the money stops slipping away.
Effective Labor Rate: What It Is and How It Compares to Your Posted Rate
The rate on the wall is what you charge for an hour that gets billed. What the shop actually earns per hour is a different number, and the gap between them is where service profit goes.
