The real cost isn't the work—it's losing money on disputes
You did the work. You deserve to get paid. But without proof, clients dispute charges, question what was done, and delay payment. You need protection—not another complex system.
No proof = No payment
Photos scattered across phones, notes on paper. When clients question the work weeks later, you have nothing to prove what you did.
Slow invoicing = Slow payment
Waiting until you're back at the office to create invoices means waiting longer to get paid. Clients forget details and delay payment.
Managing crews manually
Texts, calls, and memory to track who's where and what they did. No central place to coordinate teams and jobs.
No Hidden Fees

Frequently asked questions
Questions answered honestly
Do I need a credit card to try it?
No. Create your account and run 3 complete jobs for free. Photos, signatures, invoices—everything works. No card required. After your 3 free jobs, you'll need to subscribe to continue.
Does it work on my old Android phone?
Yes. SiteSignOff works on any smartphone (iOS or Android) from the last 5 years. If your phone can open a web browser, it'll work. No app store required—it's a web app that works offline once loaded.
Can I export my data to Excel or QuickBooks?
Yes. All invoices and job data can be exported as CSV (opens in Excel), or sent directly to QuickBooks, Xero, and Salesforce. You own your data—export it anytime, even if you cancel.
What happens if I lose my phone?
Your data is safe in the cloud. Log in from any device (phone, tablet, computer) and everything is there. Photos, signatures, invoices—all synced automatically. You can even work from multiple devices.
Is the signature legally binding?
Yes. Digital signatures are legally recognized under the ESIGN Act (USA) and eIDAS (EU). Each signature is timestamped, GPS-tagged, and cryptographically secured. Courts accept them as proof of agreement.
Can I cancel anytime?
Yes. Cancel from your account dashboard with one click. No phone calls, no emails, no questions. You keep access until the end of your billing period, and you can export all your data before you go.
