Frequently Asked Questions

Questions we hear most before contractors make the switch.

Cinderblock works both for solo operators and larger teams. If you’re a solo contractor it’s built to scale with you as you add crew. Job management, estimates, and the mobile app are useful from day one. Time tracking, user notifications, and other team features become more valuable as you grow.
Cinderblock is used by contractors across plumbing, electrical, HVAC, landscaping, roofing, painting, general contracting, and more. The core workflow — estimate, schedule, invoice, get paid — applies across trades. See all supported industries.
Yes. The mobile app supports offline use, so you can update job notes, create estimates, and track tasks in the field even without a signal. Changes sync automatically when you reconnect.
Most contractors are running jobs in Cinderblock within a day. There’s no complex setup, training, or data migration required to get started. If you do have data to import (e.g. a customers list), contact support to get your data seamelessly imported to your Cinderblock account.
Yes. Customers receive a link to review and sign documents online with no account required on their end. You can also set up automated reminders for estimates that haven’t been signed yet.
Cinderblock integerates with payment providers who support credit/debit card payments as well as ACH bank transfers. For card payments, you have the option to pass the processing fees to your customers automatically, so that you keep the full invoice amount.
Cinderblock handles job-level financials including estimates, invoices, job costs, and payments. It’s not a full accounting platform. Many contractors use both: Cinderblock for field work and job workflow, QuickBooks for bookkeeping and taxes.
Yes. You can cancel at any time. When you cancel, your subscription stays active through the end of the period you’ve already paid for and will not renew after that.

Our office runs itself now

Scheduling used to eat up half my morning. Now appointments go out automatically, customers get notified, and I can actually focus on the business instead of playing phone tag.

Laura, BTB Electric

Works even when the wifi doesn’t

I’m on job sites with zero signal all the time. The mobile app keeps working offline and syncs everything when I’m back in range. That alone sold me.

Luigi, DePinto Electric

They actually listen

We suggested a feature for tracking purchase orders and they built it within weeks. Try getting that kind of response from the big guys.
