TL;DR
The Project management and accounting (PMA) module in Dynamics 365 Finance is a project accounting engine, not a project management tool.
Most problems attributed to PMA are design and governance failures — not product limitations.

Why This Module Is So Often Misunderstood

The Project management and accounting (PMA) module in Microsoft Dynamics 365 Finance is one of the least well-documented areas from a business and governance perspective.

Microsoft documentation explains:

  • Features
  • Configuration options
  • Functional capabilities

What it rarely explains is:

  • When PMA should be used
  • What business problem it actually solves
  • What it should not be expected to do

After being involved in multiple mid-to-large Dynamics 365 Finance implementations across multiple sectors, one pattern repeats consistently:

Organizations approach PMA with a project management mindset and discover — often too late — that it enforces accounting logic instead.

This article resets that mental model.


PMA Is Not an Extension of the General Ledger

A common misunderstanding among business stakeholders is the belief that PMA is simply:

“A more detailed version of the general ledger.”

That assumption is wrong — and costly.

The general ledger exists to answer corporate questions:

  • What was spent?
  • Where does it hit the P&L or balance sheet?
  • How does it roll up to financial statements?

PMA exists to answer project-specific financial questions:

  • How do costs accumulate over a project’s lifecycle?
  • Which costs are billable, capitalizable, or expensable — and under what rules?
  • When do costs transition from operational tracking to financial reality?
  • How do approvals, budgets, and controls differ from corporate finance?

PMA introduces project subledger accounting that posts to the general ledger based on explicit project accounting rules.

Treating PMA as a GL extension usually leads to:

  • Late design decisions
  • Weak governance
  • Reconciliation issues that surface months after go-live

Why Organizations Say They Want PMA — And Why They Actually Need It

The stated reasons for implementing PMA are usually reasonable:

  • Project cost visibility
  • Billing (external or intercompany)
  • Budget monitoring

The real reason is more fundamental:

Organizations want to manage projects end-to-end from a financial and accounting perspective, not just report costs after the fact.

PMA enables:

  • Project-specific budgets and approvals
  • Project subledger accounting governed by project rules (then posted to the GL)
  • Lifecycle logic (start, execution, completion, settlement)
  • Optional capitalization and billing flows

This is not reporting.
This is financial design applied at project level.


The Most Damaging Misuse: PMA as a Project Management Tool

PMA is frequently forced into roles it was never designed for:

  • Milestone tracking
  • Deliverable management
  • Dependency and execution monitoring

This is where the most damage occurs.

PMA is very strong at project accounting:

  • Cost control
  • Cost classification
  • Billing accuracy
  • Capitalization logic

It is not a best-in-class project execution tool.

Yes, PMA includes planning constructs (WBS, activities, timesheets).
But these exist primarily to support financial control and postings, not to replace a full project management tool.

When organizations try to use PMA as a replacement for true project management tools, the result is usually:

  • Over-engineered project structures
  • Misuse of categories and activities
  • Frustrated project managers
  • Poor visibility on real progress

The irony is that this misuse often degrades both project execution and accounting clarity.


Governance Reality: PMA Reveals What Organizations Avoid Deciding

PMA does not create governance problems.
It exposes unresolved ones.

In most implementations:

  • Finance owns PMA design decisions
  • PMOs are partially involved
  • IT executes configuration

The most common breakdown appears around approvals:

  • Who approves purchase requisitions and purchase orders?
    • Line manager?
    • Project manager?
    • Corporate finance?

If this is not explicitly defined, PMA becomes the arena where corporate control and project autonomy collide.

👉 Deep dives you may find useful:

Another recurring tension is project structure:

  • Controllers want stability and reconciliation discipline
  • Project managers want flexibility and operational alignment

PMA forces these conversations. Avoiding them guarantees friction later.

Capitalization: Where PMA Quietly Becomes High-Risk

PMA is often selected specifically to support:

  • R&D capitalization
  • Capex projects flowing into fixed assets

The most dangerous assumption teams make is simple:

“We’ll define capitalization rules later.”

Capitalization logic directly impacts:

  • Project structure
  • Posting profiles
  • Cost categories
  • Integration with fixed assets

When these rules are unclear or incomplete, the consequences are predictable:

  • Erroneous opening balances
  • Weak reconciliation trails
  • Manual corrections that do not scale

Even without immediate auditor pushback, these weaknesses tend to surface during financial reviews, close cycles, or internal audits.

When PMA Should — and Should Not — Be Used

PMA is not always the right tool.

If the objective is simply:

  • More granular cost tracking
  • Enhanced reporting

Then simpler mechanisms are often better:

  • Financial dimensions
  • Tags or attributes
  • Reporting structures

👉 See:

PMA is the right tool when:

  • The organization manages many projects with clear start and end dates
  • Projects require dedicated budgets and approvals
  • Project-level accounting differs from corporate accounting
  • Billing (especially cost-based) is required
  • Capitalization or intercompany charging is involved

Using PMA everywhere “just in case” is a design shortcut.


The One Design Decision Teams Always Regret Delaying

There is one decision that teams routinely postpone because it does not appear on financial statements:

Introducing a project dimension.

Even when not required for statutory reporting, it dramatically improves:

  • Reconciliation
  • Cross-module analysis
  • Troubleshooting during close

Teams that skip it usually compensate later with manual analysis and opaque reporting.


The Mental Model That Changes Everything

After seeing PMA implemented well — and poorly — one conclusion stands out:

PMA is a project accounting tool, not a project management tool.

The worst implementations share a single root cause:

Unclear accountability between project managers, controllers, and corporate finance.

If every Dynamics 365 Finance project answered one question upfront, it should be this:

What do we consider a “project” in our organization — and how should PMA help us achieve our business goals?

Until that is clearly answered, configuration choices are guesses.


Who This Article Is For

This article is primarily for:

  • Finance directors
  • Controllers
  • ERP sponsors

It should also resonate with:

  • Senior consultants
  • Project managers transitioning into ERP environments

If PMA feels heavier than expected, more political than planned, or harder to reconcile than promised — it is rarely a tool problem.

It is a design and governance problem.
