Sunny vs. an in-house review team: people who know your deals, or an AI employee that checks every file in minutes
By Mass AI · Reviewed
This page compares a way of working, not a company. Where the answer changes from one team to the next, the table says so.
An in-house review team is your own staff reading each sold deal, chasing reps for fixes, and handing the file to ops, and it brings judgment and relationships no software has. Sunny is Mass AI's AI deal review employee that checks each sold deal against your requirements in under 5 minutes per deal, texts the rep for what is missing, and brings your team only the calls that need a person. If your volume is low enough for your people to check every file the same day, keep your team as it is, and if files wait days for review, Sunny can do the first pass so your team spends its time on the hard calls.
Side by side
Every Mass AI comparison page uses the same capability names. Where a feature has a different name or does not match one to one, the notes say so.
| Capability | Sunny | An in-house team | Notes |
|---|---|---|---|
| Sold deal review | Yes. Reads each sold deal's documents and photos against a minimum intake list plus your own rules, including whether homeowner, property, system and financial details match. | Yes. People on your team read each file against your rules. | |
| Rep follow up on missing items | Yes. Looks in your connected systems first, then texts the rep for the one thing it needs and keeps after it until the deal is fixed. | Yes, by call, text, email or chat, the way your team works today. | |
| Ops approval and handoff | Yes. Ops approves the exact package before it goes out, then Sunny sends it and checks that it arrived. | Yes. Your team owns the handoff. | |
| Homeowner messages | Only after the rep approves the exact recipient, message, purpose and project. | Depends on your team. | |
| Lead response and booking | No. Sunny starts after the deal is sold. | Not part of this job. | This page compares the deal review job only. |
| Design, proposals and contracts | No. Sunny checks the designs, proposals and contracts made in your other tools. | Not part of this job. | |
| Financing | No. Sunny checks that signed finance documents are in the deal, unless a source confirms a cash deal. | Not part of this job. | |
| Project tracking after handoff | No. Sunny's job ends when ops approves the handoff and the package arrives. | Depends on your team. | |
| How reps use it | Reps text Sunny from iMessage or SMS. No login. Ops uses the project view. | Reps hear from a person they know, in whatever channel your team uses. | |

| Setup | Mass AI learns your review rules, connects your tools, and runs Sunny on real deals with your team before anyone relies on it. | Hire people and train them on your rules. |
Where an in-house review team is stronger
- People can make judgment calls on unusual deals, odd roofs, custom adders and lender exceptions.
- Your reviewers know your reps, and a call from someone they know can get a fix faster.
- People can pick up the phone with a lender, a utility or a homeowner and talk a problem through.
- There is no new vendor, no setup and no new software to approve.
- Your team is already trusted by ops and sales, and it already knows your rules.
Where Sunny is stronger
- Sunny reviews a deal in under 5 minutes per deal, so a file does not wait in a queue for a free reviewer.
- Sunny checks every deal against the same minimum intake list plus your rules, every time, including whether homeowner, property, system and financial details match across documents.
- Sunny texts the rep for the one thing it needs and keeps after it, which takes chasing off your team's plate.
- Sunny remembers how your company works, so later reviews get faster.
Who should pick an in-house review team
Built for: Installers and EPCs whose ops, QA or project coordinators already review each deal by hand.
- Your deal volume is low enough that your team checks every file the same day it comes in.
- Most of your deals are unusual and need a person's judgment more than a checklist.
- Your reviewers have spare time, and files are not waiting.
- You are not ready to add a new vendor or a setup period right now.
Who should pick Sunny
Built for: residential solar installers and EPCs whose sold deals stall before install because files are missing things or do not match.
- Files wait hours or days for review, and the wait grows when volume goes up.
- Your team spends more time chasing reps for missing photos and signatures than making real decisions.
- You are growing deal volume faster than you can hire and train reviewers.
- You want your people to keep the final say: Sunny brings ops the hard calls with the evidence side by side, and ops approves every package.
Sunny does not replace your ops team. It does the first pass and the chasing, and your people approve each package and make the calls that need a person.
Where each option sits
A 2x2 of the options on these pages, placed only where our sources back the place.
- Sunny, under 5 minutes per deal. Reads every document and photo in the sold deal against your rules, texts the rep until it is fixed, and hands ops a package to approve.
- An in-house review team, 3 hours to 4 days per deal by Mass AI's estimate. People read the whole file, chase the rep and own the handoff, at the speed your staffing allows.
- Enerflo. Checks that required items such as a utility bill and signed loan docs are in, shows reps what to fix, sends reminders, and controls when a deal goes to ops. Whether it reads each document to check that details match is unknown, so it sits nearer the middle.
- Wave Sales, not plotted. Its public pages do not describe sold deal review. It answers and books leads.
- Viktor, not plotted. A general AI employee. Its public pages do not describe solar deal review.
- Construct, not plotted. A platform for building your own agents. Its public page does not describe solar deal review.
- Outsourced deal review, not plotted. Where it sits depends on the provider.

Questions buyers ask
Does Sunny replace my review team?
No. Sunny does the first check and the follow up with reps, and your ops team still approves every package and makes the hard calls.
When is my own team the better choice?
When your volume is low enough to check every file the same day and most deals need a person's judgment. In that case, a new tool may not be worth the setup.
What does Sunny do when it is not sure?
It stops and brings the question to ops with the evidence side by side. It does not guess on calls above its authority.
How long does setup take before my team can rely on it?
Mass AI learns your review rules, connects your tools, and runs Sunny on real deals with your team before anyone relies on it. The length depends on your rules and tools.
How do reps feel about it?
Reps do not log in to anything new. They get a text that says exactly what is missing and reply from their phone.
