Subscriptions & purchases
What does Certo cost?
Your first 3 certificates are free. After that, Certo Premium is $6.49 NZD a month for unlimited Certificates of Compliance and Electrical Safety Certificates. Inspectors buy inspection credits (one credit per signed Record of Inspection or Certificate of Verification).
How do I subscribe or buy inspection credits?
- Open Certo and sign in.
- On the Home screen, tap Subscribe (shown under your free-certificate count), or start a new certificate once your free ones are used.
- Inspectors: Settings → Inspection Credits to buy a pack.
- Confirm with Apple (App Store) or Google Play.
How do I cancel my subscription?
iPhone / iPad: Settings → your name → Subscriptions → Certo → Cancel Subscription.
Android: Google Play → your profile icon → Payments & subscriptions → Subscriptions → Certo → Cancel.
Cancel at least 24 hours before the renewal date to avoid the next charge. You keep access until the end of the paid period.
I paid but Certo still shows the free plan
On the Home screen tap Subscribe, then Restore purchase, while signed in to the same Apple ID or Google account you paid with. If that doesn't fix it, email us with the date of purchase.
Your certificates & account
Are my certificates backed up?
Yes. Signed certificates and their PDFs are backed up to Certo's secure cloud automatically when you're online, and restored when you sign in on a new phone with the same account.
Can I change a certificate after signing it?
A signed certificate can't be edited, so the record stays trustworthy. Open it and tap Amend to create a new, signed version that references the original.
How do I delete my account?
In the app: Settings → Account & Backup → Delete account. This permanently removes your account and its data from Certo's servers. Or email us from the address you sign in with and we'll do it for you.
Voice isn't filling the form
Check Certo has microphone permission (iPhone: Settings → Certo → Microphone; Android: Settings → Apps → Certo → Permissions), and that you have an internet connection. Speak each value clearly, for example "voltage two hundred and thirty".
