Make vs Zapier for Commercial Solar and Energy EPC Firms

A project moves from a signed contract to a permit application, through jurisdiction review, to an installation date, an inspection sign-off, a utility interconnection application, and finally incentive or rebate paperwork, often with weeks of waiting between each step that has nothing to do with your own team's speed. The automation opportunity isn't making the jurisdiction move faster, it's making sure nothing on your side sits waiting for a person to notice it's ready for the next step.

A typical project moves through these stages, with waiting time between each:

1. Submit the permit application after the contract is signed, then wait through the jurisdiction's review.
2. Schedule and complete the installation once the permit clears, then record the inspection sign-off.
3. File the utility interconnection application after inspection sign-off, with data pulled from your project records.
4. Submit incentive or rebate paperwork against its own deadline, tracked separately from the permit timeline.

For an EPC working in one or two jurisdictions with predictable, similar permit requirements and one utility's interconnection process, a straightforward checklist workflow in Zapier works well: each completed step triggers the next notification, and the requirements don't change enough project to project to need branching logic. This is the right starting point for most single-market operators, and it's worth confirming your actual permit and rebate paperwork really is this consistent before assuming you need something more complex.

Once you're operating across multiple counties or municipalities, each with its own permit requirements, and multiple utilities with different interconnection application formats and rebate programs with their own deadlines, a single linear checklist starts requiring a different version for every combination of jurisdiction and utility. Make's branching lets one workflow route a project to the correct permit checklist and interconnection format based on where it actually is, instead of maintaining a separate near-duplicate Zapier flow for every jurisdiction you work in.

Building the branching version in Make takes longer up front than wiring a simple checklist in Zapier, and for a single-jurisdiction operator that extra time isn't worth it. For a multi-jurisdiction operator, the calculation flips: the cost of missing one utility's interconnection window or one rebate program's cutoff, because a project sat in the wrong checklist for two weeks, is almost always larger than the extra setup time Make requires. Weigh the tradeoff against your actual project mix, not against how complex the workflow feels to build.

A useful gut check: count how many distinct permit-and-interconnection combinations you're actively juggling right now across open projects. Two or three, and a shared checklist with minor manual adjustments is still reasonable. Six or eight, each subtly different, and you're already paying the cost of that complexity in someone's head instead of in a workflow that can hold it reliably.

A multi-state EPC working with several utilities that each periodically audit interconnection paperwork, or that requires proof of a controlled, consistent process across every project team, is the case where Workato's governed recipe management starts to matter, less for the permitting logic itself and more for being able to show exactly how a given project's paperwork was generated and by what process. Below that scale, it's added governance without a matching requirement to justify it.

It's tempting to automate the whole permitting checklist end to end the moment you decide to invest in it, but most EPCs haven't actually measured where their projects sit idle the longest before building anything. Sometimes the real delay isn't a jurisdiction's review time at all, it's the two or three days a completed application sits on someone's desk before it gets submitted, or the week a signed interconnection agreement waits before anyone schedules the actual installation around it. Automating notification and handoff speed on your own side of the process often recovers more total time than anything aimed at the parts you don't control, and it's a far cheaper first project than a full branching rebuild. Spend a week timestamping every step on five recent projects before deciding where to spend your automation budget, because the answer is rarely where people assume it is, and building the wrong workflow first wastes both the setup time and the goodwill of the team who has to actually use it afterward.
