VOLTA vs. the electrical estimating spreadsheet

Every electrical shop's estimating starts in a spreadsheet, and the spreadsheet deserves respect — it priced real work for years. VOLTA is a $9.99 CAD/month browser tool with an AI-drafted takeoff. If you bid a couple of small jobs a year, a disciplined spreadsheet may honestly be enough. If bids are getting bigger or more frequent, VOLTA keeps what Excel got right — every number visible and adjustable, files you own — and takes over the part a workbook cannot: drafting the takeoff from a PDF, applying NECA-style labour factors automatically, and keeping margin and tax live.

Side by side

Where a spreadsheet is genuinely stronger

No spin: if you already have a workbook that encodes your billed rate, cost rate, markup, waste, overhead and tax, and you only bid a couple of small jobs a year, a disciplined spreadsheet may honestly be enough. You already know it. Every formula is visible. The file is yours. There is no new subscription and no new tool to learn.

VOLTA also publishes a free electrical bid template (Canada, 2026) for exactly that job — takeoff, NECA-style labour factors, margin, GST/HST and BC PST in the formulas, no email required. A template automates the arithmetic, not the takeoff. You still count every device and type every quantity, which is where bid evenings actually go.

The failure modes of a spreadsheet grow with the bids: hand-typed takeoffs, silently broken formulas, factors applied from memory. The research collected on our “what's actually free” article (from EuSpRIG spreadsheet-error studies) is not comforting, and it is not a test of your particular file. It is the reason a shop whose bids are getting bigger usually wants a reviewable starting count, automatic factors, and live margin — without giving up visible numbers or files they own. That's the job VOLTA does for $9.99 CAD a month.

How the switch actually works

You are not porting spreadsheet logic. You are moving settings. The migration article walks through it in three steps: write down the seven numbers your workbook already knows (billed rate, cost rate, typical markup, waste habit, overhead, contingency, tax); set them once as VOLTA sliders, where they persist for every bid; then take a tender you already priced in Excel and run it through VOLTA in parallel — review the AI-drafted takeoff against your old counted list, and compare both the totals and the hours spent.

What you gain immediately over the spreadsheet, once those sliders are set: NECA-style labour factors applied per line automatically (structure ×1.00–×1.75 plus conditions — the adjustment Excel users apply from memory, on the lines they remember), and a live margin readout so markup vs. margin never silently drifts. The unhealthy instincts — 11 pm takeoff typing, dragged-formula bids — can retire. The healthy ones stay.

For Canadian buyers

VOLTA is priced in CAD with GST/HST added at checkout, and its defaults follow BC rules — 5% GST on the bid, optional 7% PST on materials for real-property work, adjustable for any province. Reference rates ship calibrated to Canadian markets and every one is a slider. The free template uses the same tax idea (GST/HST and optional BC PST as inputs). More in the Canada buying guide.
