Still on Spreadsheets?

Your Spreadsheet Is Costing You 10+ Hours a Week

Excel and Google Sheets were never built for construction. Contractors who switch to DeltaPro cut invoice time by 80%, generate AI-powered bids in minutes, and never lose a change order again.

The real cost of spreadsheet construction management

Every contractor knows the frustration. Here's what it's actually costing you.

Formula errors cost you money

One broken cell in your bid spreadsheet and your $200k estimate is off by $20k. There's no audit trail, no version history that actually helps, and no way to catch it until it's too late.

AIA invoicing takes half a day

Copy last month's G703 into a new tab. Update every column by hand. Recalculate retainage. Format it to look professional. Send as PDF. Repeat 10 times a month across all your projects.

Change orders live in email threads

"Which version did the owner approve?" is a question you should never have to ask. Tracking change orders in spreadsheets and email means scope creep, disputes, and missed billings.

You don't know your real WIP

Work-in-progress reporting in Excel means manually pulling numbers from multiple files, hoping nothing's stale. Most contractors skip it entirely — until the bank requires it.

The "It's Free" Myth

Spreadsheets aren't free — you're paying with your time

If you spend 10 hours a week on admin tasks — bids, invoices, change orders, reports — and your time is worth $75/hr, that's $750/week or $39,000/year in lost productivity. DeltaPro starts at $15/month.
