A Worked Example: Financing a Commercial Solar EPC's O&M Revenue

Installation revenue tied to milestones, permitting approval, equipment delivery, commissioning, is project-based no matter how predictable your pipeline of new contracts looks. Neither Pipe nor Capchase underwrites project milestone billing as recurring revenue, since each project is a one-time engagement even if your backlog is full for the next two years. Treat this revenue the way any project-based contractor would: financed through mobilization loans, equipment financing, and receivables-based lines rather than a revenue-based product.

A multi-year operations and maintenance agreement, monitoring, cleaning, inverter servicing, billed monthly per site, behaves much closer to the recurring revenue Pipe was built to finance. If your O&M book has real contract terms, multi-year commitments, defined cancellation notice, and a documented renewal history, that's the slice worth bringing to Pipe specifically, kept separate from your project revenue in how you present the business.

An O&M book is worth bringing to Pipe when it has these traits:

• Multi-year commitments in signed service agreements, not informal yearly renewals.
• A defined cancellation notice, so a lender can see how quickly revenue could end.
• A documented renewal history showing customers keep renewing across your monitored sites.
• Reporting kept separate from installation project revenue in your accounting system.

Even a strong O&M book may not fit the contracted recurring revenue profile these providers typically finance, because service agreements in this space often include performance guarantees, weather-dependent output clauses or equipment ownership transitions that a straightforward software subscription doesn't have.t for. Ask directly if you want to be sure, but budget for Pipe, not Capchase, as the more realistic path for this revenue.

The federal investment tax credit and other project-level incentives create their own financing needs, typically bridge financing that gets repaid once the credit or incentive payment is realized, and that's a specialized category of project finance rather than something Pipe or Capchase addresses. If your firm regularly carries tax credit receivables, a lender who specifically works in solar or renewable project finance will understand that timing far better than a generalist revenue-based lender will, so keep this financing need in its own conversation.

As your O&M book grows, the case for financing it gets stronger, since a larger, more diversified base of monitored sites reduces the risk that any single contract loss materially changes your revenue. Track your O&M book's size and growth rate separately from new installation bookings in your regular reporting, since that's the number a lender will actually want to see trending upward before extending meaningful terms, more than a rising count of new projects signed.

If your firm is backed by project equity investors or a renewable energy fund rather than traditional venture capital, Mercury's venture debt product likely won't apply in the way it would for a software startup, since the underwriting logic behind venture debt assumes an equity-funded growth trajectory that most EPC and O&M businesses don't have. Mercury's banking and treasury tools are still worth using for day-to-day operations across project and O&M accounts regardless.

Firms sometimes spend weeks pursuing a revenue-based product for their O&M book before they've actually separated it cleanly from project revenue in their accounting system, which slows down underwriting on the one piece of the business that might genuinely qualify. Do the accounting separation first, even before you start talking to lenders, since a clean presentation of O&M revenue on its own is worth more to an underwriter than a longer relationship history buried inside a combined revenue number.

This comparison assumes a commercial EPC with an O&M book of its own; a residential solar installer's economics look different again, since residential financing typically runs through consumer loan or lease products tied to the homeowner rather than a business-to-business service contract. If your firm does both commercial and residential work, keep the two segments separate in any financing conversation. The same logic extends to battery storage or microgrid service: monitoring and service fees billed on a recurring schedule belong with your O&M book, while installation and commissioning revenue belongs with project financing instead, regardless of which technology it's attached to.
