VoltPro - 2026 Pricing, Features, Reviews & Alternatives

VoltPro is cloud-based contractor proposal software for electrical, HVAC, and plumbing contractors. It handles the full estimating-to-proposal workflow: import a spreadsheet or build from scratch, review real-time margin data, generate a branded PDF, and sync to QuickBooks Online.

Core capabilities:

CSV estimate import: Upload a spreadsheet and VoltPro maps columns to line items automatically. No catalog setup required to get started.

Native estimate builder: Build cost-plus estimates with section organization, drag-and-drop line items, and real-time profit and margin calculations.

Professional PDF proposals: Your logo, scope of work, and payment terms are applied automatically. Choose what pricing detail is visible to the client: flat rate, section totals, or fully itemized.

Change order management: Create a change order from any existing estimate in a couple of clicks. A new PDF generates with the scope change and a project summary alongside the original.

Estimate history and search: Every estimate saved, filterable, and searchable. Duplicate any past estimate for repeat jobs.

QuickBooks Online sync: Sync customers, estimates with full line-item detail, chart of accounts, and tax codes bidirectionally.

Smart Inbox (Pro+ plan): Forward vendor invoices by email. VoltPro parses line items and prompts review for price catalog updates.

Price catalog: Build a reference catalog of materials and labor rates.

Reusable assemblies: Group materials into assemblies for fast reuse across estimates.

Pricing: Free plan (1 estimate/month), Pro at $29/mo (unlimited estimates, PDF proposals, CSV import, manual invoice scanning), Pro+ at $49/mo (everything in Pro plus QuickBooks sync and Smart Inbox). Annual billing saves 20%.
