How Long Does ERP Implementation Really Take?

Written by Fiona McGuinness | May 19, 2026 9:57:11 AM
If you're upgrading an existing ERP system - or implementing ERP for the first time - it’s normal to have questions about timing, workload, and what the process will involve. 

Most lumber yards, dealers, and building materials distributors start with the same questions:

  • How long is this actually going to take?
  • When’s the right time to start?
  • How much of our team’s time will this require?

These are the right questions to ask early. Unrealistic expectations around timeline are one of the biggest reasons ERP projects become stressful - or stall completely.

Drawing on 30+ years of ERP implementations, primarily within the lumber and building materials industry, this guide breaks down what a realistic timeline looks like - and what you should plan for.

 

How Long Does ERP Implementation Take?

There’s no single answer, but there are realistic benchmarks.

For a typical 10-user lumber or building materials business replacing an outdated system with a mid-tier ERP solution, you should plan for 6–12 months from signed order to go-live.

The exact timeline will depend on factors like project scope, internal availability, and how closely your team works with your ERP partner throughout implementation.

After go-live, you should also plan for a 2-week ‘hypercare’ period.

This period typically includes final configuration tweaks, additional training, and hands-on support through key milestones like month-end close, inventory counts, and financial reporting.

For some GenetiQ subscription tiers, hypercare is included and can be extended if needed.

One thing many LBM businesses underestimate is how long ERP selection can take before implementation even begins.

 

When Is the Best Time to Start?

There’s no perfect time, but timing does affect how smooth your implementation is.

 

Why we don’t usually recommend fiscal year-end

On paper, year-end sounds ideal - a clean break and tidy reporting.

In practice, it creates a fixed, high-pressure deadline at exactly the time your finance team is already stretched.

ERP implementations need flexibility. Fiscal year-end gives you very little room for the unexpected.

 

Why month-end usually works best

For most distributors and building supply businesses, month-end is the most practical go-live point.

It gives you clean reporting, a clear cutover point, and less disruption to financial processes.

 

You can go live mid-month

Month-end isn’t a requirement. Many businesses successfully go live mid-month by running both systems in parallel temporarily and reconciling between them during the transition. It can work very well - as long as it’s properly planned.

 

The real deciding factor: your people

The biggest factor isn’t the calendar - it’s capacity.

Your team needs time for data preparation, testing, training, and go-live support. If you're trying to do all of that during peak season, or while juggling other major initiatives, everything gets harder.

Bottom line:

Aim for month-end where possible - but prioritize a time when your key people can focus, even if that means going live mid-month.

 

How Much of Your Time Will It Take?

When planning your ERP timeline, don’t just look at the dates - look at your team’s time commitment.

There are three key phases:

1. Before You Choose a System

This stage often takes longer than expected.

You’ll need to:

  • Research ERP options
  • Define what success looks like
  • Separate must-haves from nice-to-haves
  • Align internal stakeholders
  • Get one or more demos to ensure the system is the right fit for your business

If you’re still evaluating providers, our guide to choosing the best ERP software for lumber and building materials companies breaks down what to look for, common mistakes to avoid, and how different ERP approaches compare.

This groundwork is critical and should be built into your timeline.

 

2. Once You’ve Placed an Order

After signing, your role shifts to active collaboration with your ERP partner.

Your team will typically be involved in:

  • Data preparation and cleanup
  • Reviewing and signing off on reports and workflows
  • User Acceptance Testing (UAT)
  • Train-the-trainer or key-user training
  • Regular project meetings and decision-making
  • Refining processes as you learn what the system can do

Preparing your data early can make a significant difference to how smoothly implementation progresses, particularly when replacing older systems. A well-planned data migration also gives your team greater confidence going into go-live.

This stage of the project works best when there’s close collaboration between your team and your ERP partner, with clear communication and quick decision-making throughout. Here’s what good ERP implementation should actually feel like in practice. 

Choosing the right ERP partner matters just as much as choosing the right software. Stability, industry experience, and long-term product investment can all have a major impact on implementation success and ongoing support.

 

3. Planning Your Internal Roles

To keep things manageable, you should assign:

  • An internal project lead
  • A system owner/administrator
  • Key stakeholders across departments

At GenetiQ, we clearly define the roles we need on your side so you can plan ahead and avoid overloading the same individuals.

 

How Long Until Your Team Feels Comfortable?

It’s important to separate the time it takes to go live from the time it takes for your team to feel fully confident using the system day to day.

In the first few days after go-live, users are naturally still getting familiar.

With structured training and support, most users feel comfortable within a few weeks, with confidence continuing to build throughout the hypercare period and beyond.

We also run structured checkpoints throughout the rollout to make sure training is happening as planned, processes are working as expected, and any gaps are addressed early.

On supported GenetiQ tiers, in-system guidance and prompts help reduce the number of basic “how do I…?” questions early on.

 

Ready to Map Out Your Timeline?

Every ERP implementation - from selection to go-live and beyond - takes time, focus, and the right support.

The more space you give the project, and the more actively your team is involved, the smoother the outcome.

That’s where many ERP projects fall down. It’s also where the right partner makes a measurable difference.

We work closely with every customer from day one to make sure expectations are realistic and the project is set up to succeed.
