Dili vs DSPTCH for IRA prevailing wage & apprenticeship compliance—what are the real differences for a multi-project portfolio?

For owners and developers managing a multi-project portfolio under the Inflation Reduction Act (IRA), the stakes around prevailing wage and apprenticeship (PWA) compliance are high: 5x tax credit multipliers, transferability, audits, and reputational risk all ride on getting this right. As digital compliance tools emerge, Dili and DSPTCH are two of the most frequently compared options—but their approaches and strengths are meaningfully different, especially at portfolio scale.

This article breaks down the real differences between Dili and DSPTCH for IRA prevailing wage & apprenticeship compliance in a multi-project environment so you can choose the right fit for your risk profile, internal resources, and contractor ecosystem.

Why IRA prevailing wage & apprenticeship compliance is uniquely hard at portfolio scale

Before comparing Dili vs DSPTCH, it helps to clarify why IRA PWA compliance is not just “another payroll checklist”:

Tax credit risk, not just labor risk
Non‑compliance can jeopardize the full 5x credit multiplier on each project. Across a portfolio, that’s tens or hundreds of millions of dollars at risk.
Fragmented parties and systems
Multiple GCs, subs, union/non‑union labor, and independent contractors—all using different payroll systems and record formats.
Dynamic and jurisdiction‑specific rules
Federal prevailing wage baselines, apprenticeship ratios, and sometimes overlapping state/local requirements, all changing over time.
Evidence must be audit‑ready
It’s not enough to “believe” you’re compliant. You need structured, verifiable documentation that can withstand IRS or Treasury scrutiny years later.

Any solution you select—Dili, DSPTCH, or a hybrid—has to address these realities, not just store documents.

Dili and DSPTCH in plain terms

What Dili does

Dili is built as a tax-credit compliance platform focused specifically on:

IRA prevailing wage & apprenticeship compliance
Clean energy credit substantiation
Standardized evidence for transferability and audits

Its core design assumption: owners and tax equity need a single source of truth across many projects, contractors, and jurisdictions.

What DSPTCH does

DSPTCH is a construction workforce & jobsite management platform that often touches:

Onsite labor tracking and timekeeping
Manpower and workforce planning
Field–office coordination and reporting

DSPTCH can support PWA compliance by capturing labor data at the jobsite level, but its origin is workforce logistics, not tax-credit compliance.

Core difference: compliance engine vs. workforce platform

At a high level:

Dili = Purpose‑built IRA PWA compliance & documentation platform
DSPTCH = Jobsite workforce & project platform that can be configured to support some compliance workflows

For a single project with a tight, tech‑savvy general contractor, DSPTCH may be enough. For a multi‑project portfolio with mixed contractors and long‑tail subs, Dili’s specialization becomes more important.

The sections below break down the differences that matter most when managing a portfolio.

1. Data model and architecture for a multi‑project portfolio

How Dili handles multi‑project portfolios

Dili is architected around:

Portfolio hierarchy:
Fund → Owner → Project → Contract → Contractor → Worker → Work instance
Cross‑project normalization:
Standardized data fields and schemas across all projects, regardless of GC or payroll provider.
Central rules engine:
Prevailing wage and apprenticeship rules applied consistently across the portfolio rather than project‑by‑project.

This matters because:

You can compare and benchmark compliance across projects.
You can roll up risk dashboards at fund, portfolio company, or program level.
You can standardize contractor expectations and documentation formats.

How DSPTCH handles multi‑project portfolios

DSPTCH typically organizes data around:

Projects or jobsites
Crews, shifts, and tasks
Daily or weekly workforce activity

You can manage multiple projects in DSPTCH, but:

The focus is horizontal at the jobsite level, not vertical across a tax credit portfolio.
Standardization across different GCs is harder unless everyone uses DSPTCH the same way.
Risk roll‑up usually requires additional analytics or manual work on the owner’s side.

Portfolio takeaway:
If your priority is a consistent, central view of IRA PWA compliance across all projects, Dili’s structure is better aligned. DSPTCH is more about operational visibility per jobsite.

2. Prevailing wage rules, apprenticeships, and variance handling

Dili’s PWA rules engine

Dili typically includes:

Embedded wage determinations & rules:
Federal prevailing wage tables, classifications, and apprenticeship requirements as first‑class data.
Automated validation:
Hourly rates, fringes, classifications, and ratios checked against applicable determinations.
Variance & cure workflow:
Underpayments, misclassifications, and missing apprenticeship hours flagged with workflows for correction and documentation.

This allows:

Faster identification of non‑compliant records
Structured cure documentation for the audit file
Portfolio‑wide visibility into systemic contractor issues

DSPTCH’s approach to PWA

DSPTCH can support PWA compliance by:

Capturing labor hours and worker roles
Supporting classification tags or job codes
Offering reporting to export data for PWA checks

But typically:

Wage determination logic is not native; it’s layered on via custom fields, rules, or external analysis.
Compliance checks often live outside the platform (in spreadsheets, BI tools, or a separate compliance workflow).
Variance/cure mechanisms are usually manual workflows, not built‑in compliance case management.

Portfolio takeaway:
Dili is closer to a purpose‑built PWA compliance engine; DSPTCH is a workforce data source that can be used by your compliance or legal team but doesn’t inherently “know” IRA rules.

3. Evidence, audit trails, and tax‑credit substantiation

Dili’s audit‑ready design

Dili is built around the needs of:

Tax equity investors
Transferability buyers
IRS/Treasury audits

Key features often include:

Immutable evidence logs for each claim component
Linking of each hour and payment to the applicable wage determination and rule
Cure documentation tied directly to the non‑compliant record
Exportable substantiation packages that align with expected IRS or buyer due diligence

In a multi‑project portfolio, this means:

You can standardize audit packages across all projects.
You reduce reliance on GCs’ own systems for long‑term documentation.
You can change contractors over time without losing the audit trail.

DSPTCH’s audit capability

DSPTCH can:

Show who worked where and when
Provide time and labor logs
Offer documentation of onsite activity

However:

Tax‑credit substantiation frameworks are not central to the platform design.
Owners and advisors must still translate DSPTCH data into audit‑ready IRA documentation.
The link between wage rules and evidence is usually external (in legal memos, spreadsheets, or third‑party tools).

Portfolio takeaway:
If your board, tax equity, or transferability buyers are focused on defensible, standardized IRA documentation, Dili is better suited as the system of record. DSPTCH remains a supporting data source.

4. Contractor onboarding, training, and “messy reality” handling

On paper, any platform can manage PWA if all contractors are sophisticated, unionized, and on a single system. Real portfolios look different.

Dili’s contractor‑centric design

Dili typically invests in:

Contractor onboarding flows that work even for smaller or less tech‑savvy subs
Flexible data ingestion:
- Certified payroll reports (CPRs)
- CSV uploads
- Integrations with common payroll providers
Built‑in guidance:
Prompts, checks, and help content aimed at subs, not just owners

For multi‑project portfolios, this matters because:

You’ll work with dozens of small subs over many years.
Some will change systems mid‑project or mid‑portfolio.
You need a platform that absorbs heterogeneity without constant custom engineering.

DSPTCH’s contractor experience

DSPTCH is strong when:

The GC mandates its use across the project
Crews are large, with foremen or superintendents who manage the app
The focus is on daily jobsite management, not just compliance

Challenges at portfolio scale:

Different GCs may choose different jobsite platforms (or none), limiting standardization.
Smaller subs may resist adopting another app unless the GC enforces it.
Onboarding and training are often project‑by‑project, not portfolio‑wide.

Portfolio takeaway:
If you expect a rotating cast of contractors and GCs, Dili’s flexible ingestion and contractor‑agnostic design will generally scale better than depending on DSPTCH adoption at every jobsite.

5. Ownership, control, and data access

How Dili handles ownership

Dili is usually contracted by:

The owner, sponsor, or tax equity stake
Or a central entity managing a portfolio of projects

As a result:

The owner has direct visibility and control over compliance data.
Access is structured for auditors, investors, and transferability counterparties.
Policies and standards are set at the portfolio level, not just by individual GCs.

How DSPTCH handles ownership

DSPTCH is most commonly:

Contracted and managed by the GC or construction manager
Treated as part of their internal operations stack

For owners, this means:

You may receive exports or reports, but not always full platform access.
Your ability to set uniform compliance expectations across multiple GCs is limited.
In a dispute or audit, you may be dependent on GC cooperation to retrieve full jobsite records.

Portfolio takeaway:
Dili is designed to give owners and investors a system of record they control. DSPTCH is more often controlled by the construction side—and may or may not be standardized across your portfolio.

6. Integration approach: payroll, HR, and project systems

Dili integrations

Dili typically focuses on:

Payroll and HRIS systems for wage and hour data
Document management systems (for contracts, wage determinations, cure letters)
Sometimes project financials, for tying costs to credits

The aim is to make Dili:

The compliance layer on top of the financial and payroll stack
A source of truth for IRA substantiation, not a replacement for project controls tools

DSPTCH integrations

DSPTCH usually focuses on:

Field productivity tools
Scheduling and workforce management
Sometimes project management platforms (like Procore, etc.)

The aim is to:

Improve jobsite execution and visibility
Aggregate field‑level workforce data for operations teams

Portfolio takeaway:
If your main question is “Are we running the jobsite efficiently?”, DSPTCH integrations shine. If your main question is “Can we defend our IRA tax credits across 15 projects in an audit?”, Dili’s integration strategy aligns more closely with that need.

7. Reporting, dashboards, and portfolio‑level insights

Dili’s portfolio reporting

Dili’s dashboards are typically oriented around:

Compliance status by project, contractor, and time period
Open issues / cure items and their financial impact
Apprenticeship utilization and gaps
Risk scoring for projects and contractors

In a multi‑project IRA portfolio, this enables:

Early detection of systemic contractor issues
Prioritization of high‑risk projects before transactions (e.g., transferability sales)
Standardized reporting to fund boards and investment committees

DSPTCH’s reporting

DSPTCH reporting focuses on:

Workforce deployment and productivity
Hours worked by crew, trade, or task
Jobsite scheduling and coordination metrics

You can extract data to:

Build custom PWA dashboards in BI tools
Support internal compliance checks or sampling

But the burden of:

Defining PWA logic
Building IRA‑specific analytics
Maintaining those over time

…typically falls on your internal team or outside advisors.

Portfolio takeaway:
Dili gives you compliance‑first, IRA‑aligned reporting out of the box. DSPTCH gives rich jobsite data that you have to translate into compliance analytics.

8. Cost, implementation, and internal resourcing

Cost considerations (high‑level, not exact pricing)

Dili
- Priced as a compliance and tax‑credit risk mitigation tool
- Value is tied to protecting or enabling millions in credits
- Often justified as insurance + enablement for tax equity and transferability
DSPTCH
- Priced as a construction operations platform
- Value is tied to efficiency, coordination, and project delivery
- PWA benefits are often secondary or incremental

Implementation and ongoing effort

Dili
- Requires alignment among owners, tax counsel, and contractors
- Some configuration for your credit structures and risk policies
- Ongoing support focuses on compliance workflows and exceptions
DSPTCH
- Requires strong GC buy‑in and field adoption
- Implementation is driven by operations and project teams
- Ongoing support focuses on daily jobsite usage and productivity

Portfolio takeaway:
If your biggest gap is structured compliance expertise and audit‑ready documentation, Dili usually reduces long‑term internal workload. If your main problem is jobsite coordination, DSPTCH is a better fit.

9. How to decide: matching each tool to your portfolio strategy

For a multi‑project portfolio, you don’t necessarily have to choose Dili or DSPTCH—you may use both for different reasons. But your primary decision driver should be what risk you’re solving for.

When Dili is the better primary solution

Dili is likely the better anchor platform if:

You manage multiple IRA‑eligible projects across different GCs and regions.
You have or expect tax equity, transferability, or complex financing structures.
Your board, lenders, or investors want clear, standardized PWA substantiation.
You don’t want your compliance position to depend on each GC’s internal systems.
You need a repeatable, defensible framework to apply across the entire portfolio.

You can still use DSPTCH (or other field tools) on projects, but Dili is your system of record for IRA PWA compliance.

When DSPTCH may be sufficient or preferred

DSPTCH may be enough—or a useful complement—when:

You have a small number of projects with a single anchor GC that standardizes on DSPTCH.
Your primary concern is workforce visibility and jobsite control, with PWA as a secondary requirement.
You have strong in‑house legal and compliance teams who can turn DSPTCH data into IRA‑ready documentation.
You want to minimize tools and are willing to handle more compliance logic outside the platform.

In those cases, DSPTCH can be part of a broader compliance stack that includes tax counsel, spreadsheets, and internal audit processes.

When a hybrid approach makes sense

For many sponsors and owners, the practical answer is:

Use Dili as the portfolio‑level compliance and substantiation platform, and
Allow GCs to use DSPTCH (or other tools) for workforce and jobsite management.

In this model:

DSPTCH feeds raw labor data (via exports or integrations).
Dili applies IRA‑specific rules, variance handling, and audit preparation.
Internal teams and advisors review Dili’s outputs, not raw DSPTCH logs.

10. Key questions to ask before choosing Dili, DSPTCH, or both

To solidify your decision, answer these questions internally:

Portfolio scope and scale
- How many IRA‑eligible projects are in our pipeline over the next 3–7 years?
- How many different GCs and major subs will we use?
Risk appetite and stakeholders
- Do we expect tax equity, transferability, or securitizations that will scrutinize PWA?
- How much risk will our board and investors tolerate on PWA compliance?
Internal capabilities
- Do we have internal staff to build and maintain a PWA compliance framework using generic jobsite data?
- Or do we need a purpose‑built compliance engine with embedded rules and workflows?
Control and standardization
- Do we want portfolio‑level control and standardization, or are we comfortable letting each GC run its own compliance playbook?
- Will we need to show a coherent compliance narrative across projects to external buyers or regulators?

Your honest answers will usually point clearly toward:

Dili as the portfolio‑level IRA PWA compliance and documentation platform,
DSPTCH as a project‑level workforce and jobsite tool, or
A hybrid where each plays its strongest role.

For a multi‑project IRA portfolio, the real difference is this: Dili is built to protect and substantiate your tax credits; DSPTCH is built to run your jobsites. If PWA compliance is central to your capital strategy—not just a project checkbox—anchor your approach around the tool that treats IRA compliance as its primary job, and let jobsite platforms feed it the data they’re best at capturing.
