What is ERP implementation? Plan & best practices

Key Takeaways:

• ERP success depends on implementation, not just software choice.
  The biggest ERP failures come from rushed discovery, poor scope definition, over-customization, and weak partners — not the software itself. A disciplined, well-planned implementation sets the foundation for measurable business impact.
• A structured, phased approach prevents costly breakdowns.
  Successful implementations follow a clear sequence: discovery, design/configuration, build/testing, training/change management, and a supported go-live. Skipping steps early leads to rework, blown budgets, and low adoption later.
• The right partner and governance make results stick.
  Choosing a partner with deep process mapping, native-first design, and transparent delivery keeps projects predictable and aligned with business goals. 
   

Enterprise resource planning (ERP) systems don’t typically fail because of the software. They tend to fail because of how the software gets implemented. The difference shows up in missed go-lives, costly disruptions, and teams trapped in workarounds that never should have existed. Pick almost any “failed ERP story” and you’ll find the same culprits: rushed discovery, fuzzy scope, over-customization, and a partner that promised a smooth rollout but never showed you how they’d actually deliver it.

Choosing the right ERP vendor is critical, but even the strongest platform will fall short without a disciplined approach. When an ERP system implementation carries bad data, broken processes, or frustrated users into go-live, these issues follow the business and erode confidence from day one.

A disciplined NetSuite cloud ERP deployment does the opposite. The right ERP solution streamlines business processes, shortens close, and gives leaders the visibility they need to grow. What follows is a practical guide to implementing ERP the right way—and where to watch for the landmines.

What is ERP implementation?

Calling ERP implementation “software install + data import” is like calling a house “paint + wiring.” Real implementation rewrites how the business runs. It means rethinking processes across all business functions, migrating and cleaning data, and integrating the systems that matter. It also means teaching people a new way to work—and supporting that new way after go-live.

For midsize companies, most NetSuite implementations take 6–7 months from kickoff to stabilization. This timeline provides enough breathing room for iteration and pivots while still keeping momentum, so teams don’t lose focus or forget decisions made earlier in the project.
One key distinction is between configuring native features and building customizations. NetSuite includes powerful out-of-the-box tools, but too many teams jump straight to custom code. Sometimes it’s lack of awareness that the native solution exists; other times it’s consultants eager for extra billable work. Either way, unnecessary customization creates complexity and cost that could have been avoided.
The real skill lies in knowing when to configure what’s already there and when a true customization is justified. This judgment call is where a best-in-class ERP implementation partner makes the difference, keeping projects lean, maintainable, and aligned with long-term business needs.
Treat implementation as a strategic initiative and a core part of your digital transformation, not an IT chore. It affects the entire organization, touching every department and shaping daily work.

Why ERP implementations fail

According to Gartner, more than 70% of recently implemented ERP initiatives fail to fully meet their original business goals, and as many as one in four collapse entirely. Based on our own experience with the frequent failed implementations that come through our door asking for recovery services, those statistics ring true. These numbers highlight just how high the stakes are—and why cutting corners almost always backfires.

The failure patterns repeat:

• Shortchanged discovery. Project teams gather “requirements” at a high level and miss the details that drive scope. A distributor says “basic order management” until someone maps pricing tiers, approvals, and returns rules that change by channel.
• Leadership misalignment. If key stakeholders send mixed signals about priorities, no amount of training will overcome the resistance that follows.
• Customization first, configuration later. Over-customizing on day one recreates yesterday’s process inside new software, complicates upgrades, and inflates cost.
• Data lifted and shifted. Messy data goes in; messy reports come out. Confidence erodes.
• The wrong partner. Inexperienced or offshore implementation teams often lack the accountability and visibility that keep projects on track. At Anchor Group, our internal project data shows we’ve completed hundreds of NetSuite deployments with 98% of tasks staying within budget (≤10% or ≤2 hours variance). We put in the hard work necessary for on-budget projects.

Quick-and-dirty ERP implementation projects tend to break down. The mistake isn’t just skipping documentation—it’s treating requirements as a one-time task instead of an iterative process. Every conversation uncovers another layer, and the best way to surface these needs is through early “show and tell.” Put drafts, demos, or even rough system sketches in front of users and let them react. This kind of interaction exposes gaps far earlier than static documents ever will.

At Anchor Group, we build this into our approach. Our NetSuite consultants use working models and process flows from the start so stakeholders can point, question, and refine in real time. This iterative style keeps scope grounded in reality and prevents the misalignment that drives scope creep later.

The ERP implementation process: Key phases

ERP rollouts succeed when they follow a clear sequence. Each phase builds on the last, and skipping steps early almost always means problems later. Here’s how a disciplined NetSuite implementation typically unfolds.

1) Discovery & planning

ERP projects often start to fail here. Weak discovery creates cracks that widen later—unclear scope, overlooked exceptions, and unrealistic timelines. Getting strategy right in this phase gives execution a fighting chance. Discovery is where you surface the real work, define business needs, size it honestly, and decide what not to do.

In this phase:

• Document current-state workflows across business units, including exceptions where complexity hides—especially in areas like order management and the supply chain.
• Identify bottlenecks that slow orders, cause rework, or break hand-offs.
• Assess data quality—duplicates, stale SKUs, inconsistent naming—and decide what to archive or standardize.
• Design future workflows that seal the cracks.
• Define scope and timelines based on capacity, complexity, and validated business requirements, not “hero hours.”

This level of detail is where Anchor Group stands apart. Our consultants work area by area—designing processes like inventory, pricing, approvals, or service flows, then moving straight into configuration. This keeps momentum, reduces rework, and makes scope and effort clear as the project unfolds.

2) Design & configuration

Design translates insights into a system people can live in.

During this phase:

• Configure NetSuite roles, forms, workflows, and approvals with a “native-first” mindset.
• Plan integrations: what stays outside NetSuite—like customer relationship management (CRM) systems or marketing automation platforms—how data flows, and how errors are handled.
• Lock the data migration strategy: what history to move, how to transform it, how to validate it.
• Establish security and access rules that balance usability and control.

These decisions set the foundation for everything that follows. Clear designs and disciplined configuration make the build phase far smoother and reduce costly surprises later.

3) Build & test

Build brings the design to life. Testing proves it works in reality.

In the build and test phase:

• Configure NetSuite to spec and validate with role-based, real-world scenarios.
   
• Migrate data in controlled waves, with reconciliation reports for accuracy.
   
• Develop and test integrations (IDs, events, retries, error surfacing).
   
• Track issues in a visible queue and burn them down each sprint.

Thorough testing at this stage gives you confidence to move forward, knowing the system can handle day-to-day realities before anyone relies on it in production.

4) Training & change management

Change management ensures people buy in. Training ensures they know how.

Here’s what Anchor Group recommends:

• Explain the “why” before the “how.” Tie changes to faster close, cleaner audits, stronger decision-making, or fewer stockouts.
• Recruit functional champions from finance, business operations, and human resources who can support peers and reality-check gaps.
• Train by role, in the system, with the data that team members and end-users will see post-go-live. Use short sessions, labs, and quick reference guides.
• Build documentation that your internal team can own and update long-term.

Strong change management and hands-on training turn a new system from a source of resistance into a tool employees trust. This paves the way for a smoother go-live.

5) Go-live, stabilization & ongoing support

Go-live should be a cutover, not a cliff. Plan it this way from the start.

Here’s how to launch smoothly and stay on track:

• Finalize data syncs and user access.
   
• Run cutover checklists and set escalation paths.
   
• Staff hypercare so users get quick answers in the first weeks.
   
• Track incidents during stabilization, then shift into a release cadence for continuous improvement.
   

This stabilization window typically spans a few weeks, giving teams hypercare support and space to fine-tune workflows, integrations, and configurations. For businesses that want to keep that momentum going, our NetSuite Managed Services provide ongoing administration and optimization long after go-live.

ERP implementation best practices (that actually move the needle)

Best practices aren’t just a checklist. They’re guardrails that keep you from sliding into the overruns, delays, and adoption problems that can sink ERP projects.

Planning & governance

Getting governance and project management right is about more than paperwork. A well-defined ERP implementation plan creates the framework that keeps scope, budget, and stakeholder expectations aligned.

• Set measurable objectives (e.g., cut month-end close from 10 to 5 days).
• Run the project on a single source of truth (scope, timeline, budget, risks) documented in a clear project plan that keeps everyone aligned.
• Sequence work based on business outcomes, not just NetSuite modules. Prioritize the processes that deliver the most impact—like shortening close or speeding up order fulfillment—then build supporting features around them.
  Invest real time up front—discovery and design save weeks later.

Taken together, these steps keep the project grounded in business outcomes and give leaders visibility into what’s happening at every stage.

People & leadership

The people you assign to the project often determine whether it succeeds or fails.

• Staff an A-team with real availability and executive sponsorship.
• Choose the right partner. Local, consistent teams ensure accountability in ways offshore groups rarely can.

With the right leadership support and an implementation partner you can trust, teams can stay aligned and motivated to carry the work forward.

Data & integrations

Clean, reliable data is the backbone of any ERP system. Integrations act more like the veins, carrying this data where it needs to go. Both matter, but without strong data at the core, even the best integrations won’t hold the system together.

• Clean data first. Standardize, de-dupe, and reconcile.
• Design integrations early, with IDs, events, and monitoring in place.
• Resist unnecessary customization. Start native, customize only with clear ROI.

With this groundwork in place, information flows smoothly across functions at go-live, whether the system is cloud-based or on-premises, rather than breaking down into silos.

Adoption & support

User adoption doesn’t happen automatically—it needs planning, reinforcement, and ongoing support.

• Make change management a dedicated part of the project. Recruit functional champions who guide peers and surface issues early.
• Test thoroughly with real scenarios and edge cases.
• Provide role-based training that uses real workflows and data team members will see after go-live.
• Continue support after launch with refreshers, updated guides, and time for users to adapt as the system evolves.

Handled well, these practices build long-term confidence in the system and keep teams engaged after the initial wave of go-live excitement fades.

Measuring implementation success

Knowing whether an ERP implementation “worked” isn’t as simple as asking if the system is live. Plenty of projects go live and still fail to deliver value because users avoid the system, reports are unreliable, or processes remain broken. Success needs to be measured in layers: what happens during the project, immediately after, and over the long term.

• During the project: Watch leading indicators like milestone completion, user acceptance testing (UAT) pass rates, defect resolution trends, and data reconciliation. These show whether the work is tracking to plan or masking problems that will surface later.
• First 30/60/90 days: Early adoption metrics tell you if the change is sticking. Track user logins, help-desk ticket volume, and time-to-resolution. Operational KPIs like time-to-close, time-to-cash, and on-time fulfillment reveal whether the system is helping or slowing things down.
• 12-month outcomes: Long-term success shows up in business results. Inventory turnover, forecast accuracy, days sales outstanding (DSO), and margin lift are proof that the system is driving efficiency and profitability, not just running in the background.

A better measure of success isn’t just that the system went live—it’s whether core financial processes improve. If month-end close takes longer than it did before, or if the business struggles to reconcile transactions accurately, the implementation hasn’t delivered. Success shows up when the system supports faster, more reliable reporting over time.

The risks of offshore or inexperienced partners

When ERP projects spiral out of control, companies often blame the software. But these days, most major cloud ERP systems are solid. The real difference comes from the ERP implementation partner. Offshore teams may come cheap up front, but the hidden costs pile up in missed requirements, unclear communication, and revolving-door resources. The result? Budget creep, blown timelines, and frustrated employees who start building workarounds before the system is even live.

Anchor Group’s model is built to avoid these traps. Our projects are led by US-based consultants who know the industries we serve: wholesale, manufacturing, and B2B ecommerce. The people you meet in discovery are the same people guiding you through go-live and beyond. And instead of vague promises, we show you detailed process flow maps up front so you know exactly what you’re getting.

Here’s how we keep projects on track:

• Consistent teams. No surprise hand-offs to junior offshore staff.
• Process flow maps early. We review the areas most critical to scope—like inventory, pricing, or approvals—and dig into them at the right depth during evaluation. This way, the team goes into kickoff with realistic expectations and fewer surprises.
• Transparent tracking. We monitor scope, timeline, and budget in the open with clear dashboards.
• Customization with discipline. We only customize when there’s a business case and a plan to maintain it.
  Together, these practices keep projects predictable and results measurable. When ERP projects miss deadlines or run over budget, it usually points to weak discovery and poor governance—not inevitability. Our approach is built to reduce those risks from the start.

The Anchor Group advantage

Every ERP project starts with the same risks: scope creep, messy data, resistance from users, and the temptation to over-customize. Anchor Group’s advantage is that we’ve built a methodology to flip those pitfalls into predictable wins.

• Depth at the start. We don’t rush discovery. Our process maps surface complexity before it derails scope or budget.
• Native-first design. We configure NetSuite to deliver as much as possible out of the box, keeping upgrades clean and reducing cost.
• Disciplined delivery. Visible dashboards, sequenced rollouts, and tight change control keep projects predictable. We have the courage to be held accountable for our action items, and we help you stick to your task deadlines too.
  Adoption that sticks. Role-based training, functional champions, and empathetic and substantial support turn skeptics into advocates.
• Local support. The same consultants who design your system stay engaged after go-live, so context and continuity aren’t lost. This also means we are constantly learning from our past mistakes, unlike short-term consultants to fly in, make a big change, and then fly away, leaving you to deal with the consequences without them.

The results speak for themselves

Our clients have cut month-end close times by days, reduced order-to-cash cycles, and improved forecast accuracy—all while staying within budget and on time. Here are two case study examples:

• Medical Innovations (11-person team): Used NetSuite, SuiteCommerce, and Anchor Group automations to build a scalable operation—running like a company five times its size and tripling growth potential without tripling headcount.
• Altus Brands (ecommerce retailer): Automated half-finished electronic data interchange (EDI) transactions. In just one small project they eliminated $30,000 to $40,000 per year in manual labor and freed up finance staff for higher-value work.

Anchor Group’s promise isn’t just implementation; it's a lasting partnership. We measure our success by the KPIs that matter to you, and we stay on to make sure you keep hitting them.

ERP implementation results that stick

ERP software doesn’t make or break your business. Implementation does. The organizations that succeed treat it as a strategic initiative, invest up front, and choose partners who prove their methodology with real examples—not just marketing slides.

Ask potential partners to share their process documentation, back it up with relevant KPIs, and introduce you to the delivery team before you commit. That last part is probably the most important. Get some face time with the real people who will be actually doing the work before you make a decision.
