Pulley vs. Carta for a Solar EPC's Company Equity

A project's special purpose entity, the one holding the investment tax credit and the tax equity investor's partnership flip structure, is not something you track in a company cap table tool, and it isn't equity in your EPC business. It's project finance. Keep it entirely separate from the conversation about who owns a piece of the company that designs, sells, and builds the projects. Mixing the two in one conversation with a project manager, implying their company equity is somehow tied to project-level tax equity, creates confusion that's hard to walk back.

This distinction is easy to state and surprisingly easy to blur in practice, especially when the same senior people are negotiating both the tax equity partner's terms on a project and a key hire's compensation package in the same week. Keep the two conversations, and the two sets of documents, in entirely separate files.

List every project manager, senior engineer, or business development lead who's been told, formally or informally, that they'll get a piece of the company. EPC firms in this space grow fast when the pipeline is strong, and it's common for a founder to make several verbal promises in a hot hiring season without writing any of them down.

This is also the moment to note who, if anyone, has a direct financial stake in a specific project's tax equity structure, since a project manager sometimes also co-invests personally in a deal they're delivering. That personal investment is separate from company equity and belongs in its own record, reviewed by the person's own tax advisor, not folded into the company cap table conversation.

A senior engineer or project manager who's core to closing and delivering projects but isn't a true business partner usually fits phantom equity tied to a company-wide or division-level EBITDA formula. Reserve real equity for a genuine co-founder or someone taking on real business risk alongside the founders, not for a strong performer you want to keep through the next project cycle.

Because project-level tax equity structures can affect how income flows to the company and, in some structures, to individual owners, the accountant handling your company equity plan needs to actually understand the tax equity side too, not just standard corporate cap table mechanics. A generalist CPA who's never worked with a partnership flip structure can miss how the two interact on the company's own financial statements.

Pulley fits an EPC firm with a small founding team formalizing phantom equity for a few key project or engineering leads, wanting a clean setup without much overhead. Carta fits once you've raised outside capital into the company itself (separate from any project-level tax equity), added a board, or are consolidating with another regional installer and need a single, audit-ready ownership picture.

Solar and energy EPC growth tracks the project pipeline, closing a large commercial portfolio deal, adding a new utility territory, more than the calendar. Tie your equity and phantom equity review to those milestones, in addition to an annual check, so grants keep pace with how fast the business is actually adding scope and people.

Some EPC firms pay a project manager a bonus tied to a specific project's margin and informally call it "their equity in the deal." It isn't equity, it's a project bonus, and calling it equity sets up a future misunderstanding about whether the person actually owns anything in the company. Keep the language precise: project bonuses are project bonuses, and company equity, real or phantom, is a separate, documented thing.

Utility interconnection queues and local permitting timelines can push a project's completion out well past the original schedule, for reasons entirely outside a project manager's control. If a phantom equity formula is tied to project completion timing rather than the work actually delivered, a permitting delay can unfairly wipe out a payout the person earned through good execution. Write the formula around controllable outcomes, quality of delivery, safety record, client retention, rather than timelines that depend on a utility or a local jurisdiction.

Work through the runbook in this order:

1. Keep project tax equity inside each special purpose entity completely separate from equity in the EPC company.
2. List every project manager, engineer, or business development lead who has been promised company-level equity, formally or informally.
3. Choose real equity for genuine co-founders and phantom equity tied to a company or division formula for key contributors.
4. Bring in a CPA who understands both project-level tax equity and company equity plan mechanics.
5. Pick Pulley or Carta based on whether outside capital has entered the company itself, then review on pipeline milestones.
