5 Reasons Small Manufacturers Should Use an Outside Project Manager for Their ERP Implementation

Every ERP implementation needs a strong project lead on the client side. Most small manufacturers do not have one to spare.

The usual plan is to hand the project to the controller, the operations manager, or the owner. They already have full-time jobs, and the project needs 20 to 40% of someone's week for months. When the busy season hits, the ERP slips, decisions stall, and the timeline and budget grow.

Your implementation partner manages their side of the work. Someone still needs to manage yours. Here are five reasons small manufacturers bring in an outside project manager to fill that role.

1. Your Team Already Has Full-Time Jobs

In a small manufacturer, the people who know the business best are also the ones keeping it running. Asking your controller or operations manager to also run an ERP project usually means one of the two gets less attention. Most of the time, it is the ERP.

An outside project manager carries the coordination work, so your people can focus on the decisions and testing only they can do.

Tip: Before you assign the project internally, list what that person would stop doing to make room for it. If the list is short or empty, you need help.

2. You Need Someone on Your Side of the Table

Your implementation partner has a project manager, and that person does important work. Their job is to deliver the partner's scope on the partner's plan. Your business needs someone focused on your budget, your timeline, and your outcomes.

An outside PM reviews scope, change orders, and invoices with your interests in mind. They ask the questions you may not know to ask — before a small gap turns into a large change order.

3. They Have Done This Before

Most small manufacturers implement an ERP once every 10 to 15 years. An experienced ERP project manager has been through it many times. They know where projects usually go wrong: data migration that starts too late, testing that only covers the happy path, and cutover plans that are missing a step.

Tip: Ask any PM you interview to walk you through a project that went sideways and what they did about it. The answer tells you more than a resume.

4. Decisions Keep Moving

ERP projects stall when decisions wait. Should we track lots on this item? Which reports do we really need? Who approves the chart of accounts? An outside PM keeps a decision log, follows up on open items, and brings the right people together so the project does not wait on a busy calendar.

They also run the basics that small teams often skip: a weekly status report, a list of risks and issues, and a regular steering meeting with leadership.

5. Delays Cost More Than the Help

Every month a project runs late adds partner fees, internal time, and the cost of running old and new systems side by side. A part-time outside PM is usually a small fraction of the total project budget, and the help can scale up for testing and go-live and back down during the build.

What to do now: Look at your partner's estimate and add up what one extra month would cost. Compare that number to the cost of part-time project management.

What an Outside PM Does — and What Stays With You

An outside PM handles	Your team still owns
A client-side project plan aligned with the partner's plan	Decisions on scope, budget, and go-live
Weekly status reports and steering meetings	Knowledge of how your business runs
Risk, issue, and decision tracking	Key user time for design, testing, and training
Review of change orders and invoices	Final sign-off on testing and cutover
Coordinating key users, finance, and IT	Long-term ownership of the system
Go-live readiness and cutover planning

Your implementation partner still configures the system, builds any extensions, and loads the data. An outside PM makes sure all three groups are working from the same plan.

Start Where You Are

You do not need to hand off the whole project to get value from outside help. Some manufacturers bring in a PM from kickoff through go-live. Others start with a short project review before signing a partner proposal, or partway through when dates start to slip.
