Many retrofit teams start with an Excel sheet, Google Sheet, PDF checklist, or simple Many lighting retrofit teams compare lighting audit software and templates because both can help collect site data. A template is familiar, cheap, and flexible. Software becomes useful when the audit has to support quoting, rebates, installation costing, ROI, and proposal output. The real question is not whether a spreadsheet can collect fixture data. It is whether it can carry that data cle

A lighting retrofit can look like an easy win on paper, but the proposal still has to prove the numbers. Building owners and facility managers want to know how much energy the project will save, how long payback will take, what rebates may apply, and which assumptions were used. That is where a clear ROI calculation matters. A strong lighting retrofit proposal should show annual kWh savings, demand savings, maintenance impact, estimated rebates, net installed cost, and simple

What is a lighting audit? A lighting audit is a structured review of a building’s existing lighting system. It captures fixture counts, lamp and driver details, operating hours, controls, energy rates, and site conditions so a team can identify waste, calculate savings, estimate rebates, and build an accurate retrofit proposal. What a lighting audit actually does A lighting audit is not just a count of fixtures. Its job is to answer five practical questions: What is installed

Most contractors do not struggle to complete a lighting audit. The slowdown happens after the walkthrough, when fixture counts, notes, pricing, rebates, and proposal details have to be rebuilt across spreadsheets and separate documents. That is why lighting audit software for contractors should do more than capture site data. It should help your team move from audit to retrofit quote faster, with fewer handoff errors and a cleaner proposal at the end. If you are comparing too

A lot of contractors start with Excel for retrofit quotes, and for small jobs, that can work. The problem starts when projects get more detailed, more repetitive, and more time-sensitive. At that point, the real comparison is not Excel vs Lighting Proposal Software on cost alone. It is whether your current quoting process is slowing down proposals, creating inconsistencies, and making it harder to win work. That is where lighting proposal software starts to make more sense. F
