OpenPhone vs. KrispCall for Commercial Solar and Energy EPC Firms

Selling commercial solar or an EPC contract usually means calling through a list: inbound quote requests, canvassed leads, referrals from past projects. That's the job Close is built for, pairing a power dialer with a pipeline so a sales rep can move through calls quickly and log outcomes without switching tools. Sales reps in roles like this carry real compensation on the line; national pay for sales representatives runs from around $39,000 at the lower end to well over $130,000 for top performers¹, which makes the hours a rep spends manually dialing instead of talking to prospects a genuinely expensive way to run a sales team.

OpenPhone and KrispCall both handle outbound calling fine, but neither is built around working a list at volume the way a dedicated sales dialer is.

Once a deal closes, the job shifts to coordinating installers, electricians, and subcontractors across an active project, plus keeping the customer updated on timeline. This is a shared-inbox problem: more than one person, a project manager and maybe an office coordinator, needs to see the same conversation history with a given customer or subcontractor rather than everything routing through one person's personal cell.

OpenPhone's shared team inbox fits that job well for a small EPC firm, letting a project manager step away for a site visit without the office losing visibility into what a customer or sub was told.

Calling a utility company about interconnection paperwork or a permit status is its own particular kind of phone work: long hold times, being transferred between departments, and needing to reach the same utility rep again later in the process. Recording these calls, or at least keeping detailed notes on who said what, protects you if a utility's timeline commitment doesn't match what actually happens weeks later.

Neither OpenPhone nor KrispCall changes how slow a utility company is to answer, but a shared record of these calls means the next person who has to follow up isn't starting from zero.

Use these habits to manage utility calls well:

• Note who you spoke with at the utility, the date, and what they committed to on every substantive call.
• Record or summarize calls about interconnection paperwork and permit status so you can push back when timelines slip.
• Expect long holds and transfers between departments, and keep a shared record so anyone can reach the same utility rep again later.
• Follow up in writing on any commitment a utility representative makes by phone.

A firm running one or two projects at a time can usually manage project coordination with a single shared line and one or two people. A firm scaling to run many active installations simultaneously starts to need dedicated operations management overseeing that coordination; the median pay for general and operations managers nationally runs around $105,000², which is worth weighing against the cost of a missed subcontractor call that pushes a project timeline out by days.

As that operations function grows, KrispCall's call queuing and routing across a small team can help more than a single shared inbox does, since it spreads incoming calls across whoever is actually free.

Most commercial solar and EPC deals involve a financing partner somewhere in the process, whether that's a lender, a lease provider, or a tax-equity investor, and coordinating with them by phone often runs on a different schedule than either sales or installation calls. Losing track of a financing partner's questions or documentation requests can delay a project's funding and, by extension, its start date.

Treat these calls with the same shared-visibility approach as project coordination: whoever is managing the deal should be able to see the history of what a financing partner asked for and when, even if a different team member originally took the call. A missed document request from a lender is one of the more common, and most avoidable, reasons a project's funding gets pushed back a month, and it is entirely preventable with a shared record everyone on the deal can see.
