12 Things to Know Before Your First SyteLine Go-Live

1. Go-Live Is a Business Event, Not an IT Event

If only IT is excited, there is a problem. Operations, purchasing, shipping, and accounting each need to own their part. Name one go-live lead with authority to make decisions, and one simple way for anyone to ask for help.

2. Clean Data Before You Load It

Duplicate parts, wrong units of measure, and out-of-date routings go live just as faithfully as the good records. Allow real time for cleanup, and involve the people who know the parts, not only the people who know the system.

3. Choose the Cutover Date Deliberately

Avoid year-end, physical inventory, and your busiest shipping weeks. Beyond that, there is a genuine trade-off:

• Start of a fiscal period: Each month's financials come from one system, which keeps reporting and reconciliation simple. But finance is closing the previous month in the old system just as everyone is learning the new one.
• Mid-period: Gives operations a couple of weeks to settle before the first close in SyteLine. But that month's results are split across two systems and have to be combined.

Agree the choice with finance early. The month-end close checklist shows what the first close in SyteLine will involve.

4. Shrink Open WIP Before Cutover

Moving hundreds of partly finished jobs between systems, with their costs and progress, is slow and error-prone. Where you can, stop releasing new jobs in the old system ahead of cutover, finish the open ones into inventory, and start new work in SyteLine.

Jobs that must carry over need an agreed method, such as loading the remaining work as new jobs and handling the costs already incurred through finance, and they should be tested in a conversion rehearsal.

5. Purge Stale Purchase Orders and Customer Orders

Open orders that should have been cancelled years ago do immediate damage. An old purchase order line that the vendor will never ship tells planning the material is coming. An old customer order line tells planning you are short. Review every open line before conversion: cancel the dead ones and confirm quantities and dates on the rest.

6. Count Inventory at Cutover

Opening balances set the tone for months. If they are wrong, every later discrepancy is harder to explain, which is at the heart of why inventory doesn't match the shelf. Plan a count over the cutover, by location and lot where relevant, and load counted quantities rather than carrying over balances from the old system unchecked.

7. Test Real Scenarios, Including Exceptions

Run the full cycle with the people who will do it every day: enter an order, release a job, report labor, receive a purchase order, ship, invoice, and close. Then test what goes wrong: a partial shipment, a split operation, an order cancelled after material was issued, a scanner that will not read a label. Practise correcting mistakes too, using how to fix errors safely in SyteLine.

8. Test Security With Real Logins

Roles that are too broad let people do things they should not. Roles that are too tight stop a buyer from updating a vendor on day one. Have testers log in with the exact roles they will use in production, not an administrator account.

9. Test Hardware, Labels, and Documents in the Real Environment

Scanners drop off Wi-Fi in steel racking, label printers clip barcodes, and customers reject invoices missing their PO number. Walk the plant with real devices, print real travelers, labels, packing slips, and invoices, and keep someone available to adjust document layouts during the first days.

10. Rehearse the Cutover and Agree What "Stop" Means

Rehearse the sequence: freezes, final data loads, counts, checks, and sign-offs. The first rehearsal always uncovers missing steps. Agree beforehand which problems you will live with and which would pause or reverse the go-live, and who makes that call.

11. Put Helpers Where the Work Happens

During the first weeks, keep project team members and key users on the shop floor, at receiving, in shipping, and beside customer service, not in a meeting room. Train by role rather than by screen: people need to know their own day. A day in the life of a shop floor user is the kind of role view that helps, along with the ten screens new users actually need.

12. Watch the Journals and Expect a Rough Start

In SyteLine, operational transactions create entries in distribution journals before they reach the general ledger. During the first weeks, have finance review and post those journals daily, so missing accounts and setup problems are caught while they are small, not at month-end.

And expect friction. A successful first week is not error-free. It means shipments leave, critical material is received, and everyone knows what needs fixing tomorrow. Output often dips while people build new habits, so plan staffing and customer commitments for that.

A Composite Example

This is a composite of a pattern that comes up often, not a single client.

A ductwork manufacturer goes live on January 2, planning to carry over four hundred open jobs. On Monday, operators cannot scan smudged travelers, planners cannot issue coil because of negative starting balances, and the controller is buried in the prior year-end.

By Wednesday the plant changes course. Open legacy jobs are finished on paper and closed out separately, only new orders get SyteLine jobs, and experienced planners are stationed at receiving and the busiest work center. Orders are flowing again within days. Fewer carried-over jobs, a counted opening balance, and a date away from year-end would have avoided most of it.

Go-Live Readiness Checklist

• Go-live lead and help channel named
• Data reviewed by the people who know it
• Cutover date agreed with finance, away from year-end and peak periods
• Open WIP reduced, with a tested method for anything carried over
• Stale purchase order and customer order lines cancelled
• Inventory count planned for cutover
• Real-scenario and exception testing signed off by users
• Testers used their real security roles
• Devices, labels, and documents tested on site
• Cutover rehearsed and stop criteria agreed
• Floor support scheduled for the first weeks
• Daily journal review assigned in finance

FAQ

How long do problems usually last after go-live?

It depends on scope, data quality, and training. Plan for several weeks of extra support and closer monitoring, and ask your implementation partner for an expectation based on your project.

Should we run the old and new systems in parallel?

Full parallel running, entering every transaction twice, is rarely practical in manufacturing because it doubles the workload and the two systems quickly disagree. A rehearsed cutover with a clear rollback plan is usually more reliable.

What should we do if an inventory balance is wrong on day one?

Keep production moving, count the location, correct the balance with a documented adjustment and reason code, and note the cause so the same error is not repeated.

How long should we keep the old system available?

Keep read-only access, or a reliable archive of its data, for as long as your record-retention, tax, warranty, and audit obligations require. Confirm that period with finance before switching it off.
