This article includes insights from Kevin Howes II, Director of AX/Finance & Operations at GraVoc. He leads our Microsoft Dynamics 365 Finance & Operations implementations and post-go-live stabilization initiatives.
Implementing an enterprise ERP like Microsoft Dynamics 365 Finance & Operations (F&O) is a major operational and financial investment. But many organizations learn that the real challenges arise after go-live – when functional gaps surface, reporting expectations aren’t met, user adoption declines, and projected ROI is harder to realize than planned.
We are often brought in for what clients describe as a “rescue mission.” Their Dynamics 365 F&O environment is live, but not stable.
Integrations are failing; month-end close stretches longer than expected; reconciliations require manual intervention; and reporting is lacking. User adoption slows and spreadsheets return. What was positioned as transformation begins to feel like disruption.
As our Director of AX/Finance & Operations, Kevin Howes II, puts it: “The first 90 days post go-live determine whether the company builds confidence in Dynamics 365 F&O or quietly works around it.”
Based on years of guiding Dynamics 365 F&O implementations and post-go-live recoveries, Kevin shares the eight most common reasons Dynamics 365 F&O projects falter early and what CFOs can do to stabilize them.
1) Treating project go-live as the finish line
What it looks like:
Leadership disbands the project team, support is understaffed, and unresolved issues pile up fast.
Why it happens:
Go-live is viewed as the finish line instead of the start of operational stabilization. Budget and leadership attention shift before performance is proven under real conditions.
How to overcome it:
Establish a formal 60–90-day stabilization phase before go-live occurs.
- Maintain defined functional and technical ownership
- Track measurable success metrics
- Hold executive checkpoints for the first 60-90 days
2) Month-end close was never truly rehearsed
What it looks like:
Close takes far longer than expected and requires heavy manual intervention.
Why it happens:
Testing focused on transactions, not a full end-to-end close cycle. Edge cases, reversals, and late adjustments were not simulated.
How to overcome it:
Run at least one full mock close in UAT, including corrections, reversals, and late entries — not just happy-path scenarios.
3) Master data ownership is undefined
What it looks like:
Inconsistent setup across vendors, customers, items, and financial dimensions.
Why it happens:
Data governance was deferred until after go-live. Inconsistencies in legacy data were migrated forward. Stabilization fails quickly without disciplined data governance.
How to overcome it:
Assign clear data owners and approval workflows. Document standards before volume and exceptions increase.
4) Reporting expectations don’t match reality
What it looks like:
Executives can’t find trusted or familiar reports.
Why it happens:
Reporting was deprioritized during implementation. It was assumed dashboards and refinements could be built “after go-live.”
How to overcome it:
Align leadership early on what reports will exist at go-live versus post-stabilization. Publish a reporting roadmap and prioritize high-impact financial visibility first.
5) Manual workarounds in an expensive new system
What it looks like:
Spreadsheets resurface. Offline tracking systems reappear. Data exports to Excel increase.
Why it happens:
Early defects and unfamiliar workflows push users to bypass the system. Inadequate reporting leads to manual data exports and use of Excel.
How to overcome it:
Track workarounds explicitly. Classify them by financial and operational risk. Assign owners to eliminate high-impact workarounds first.
6) Security roles don’t align with real-world processes
What it looks like:
Users can’t complete daily tasks without admin or super user intervention.
Why it happens:
Security was designed in theory, not validated end-to-end during CRP’s and UAT.
How to overcome it:
Test security roles using real job scenarios and adjust roles based on actual workflows, not org charts. In-depth, business scenario-based security reconfiguration for all affected users/roles can be done quickly with the help of system experts.
7) Integration failures surface at scale
What it looks like:
Data errors spike as transaction volumes increase.
Why it happens:
Integrations weren’t stress-tested under real conditions. Often, integrations are unit tested under limited datasets rather than tested at the larger volumes seen in an average workweek.
How to overcome it:
Monitor integrations daily post-go-live and define clear ownership for exception handling and root-cause fixes. Define new scenarios that are causing integration breaks and seek development assistance to patch up issues.
8) Training didn’t support adoption
What it looks like:
Users rely on super users or revert to old habits. Error transactions piling up each day have to be resolved in bulk well after they should have been closed.
Why it happens:
Training was too early, too generic, or too detached from daily work. Process documentation may have been incomplete or inaccessible.
How to overcome it:
Reinforce training post-go-live with role-based refreshers tied to actual business scenarios. Support it with an accessible, structured process documentation library.
Key Takeaways
For CFOs, the first 90 days after a Microsoft Dynamics 365 F&O go-live define financial confidence.
Can you trust the numbers? Has close improved or slowed? Are reconciliations cleaner or more manual? The answers determine whether your ERP investment delivers ROI or introduces new risk.
In our experience, most post-go-live challenges can be remediated with the right planning, ownership, and stabilization focus.
If you are within your first 90 days, or still feeling instability months after go-live, a structured business process review can quickly identify where confidence is eroding and where targeted intervention will have the greatest financial impact.
