Teams that stopped chasing paper
“Renewals used to mean printing, scanning and a week of reminders. Now the tenant signs on their phone and we have the sealed copy the same afternoon.”
“Our lawyer asked what would hold up in a dispute. The audit trail and timestamp were the answer.”
“Paying in shillings by M-Pesa decided it. Every other tool wanted a dollar card.”
Questions
Is an electronic signature legally binding in Tanzania?
Yes. The Electronic Transactions Act 2015 recognises electronic signatures. The audit trail, identity check and seal give you the evidence to rely on it.
Do signers need a MirraSign account?
No. Signers get a private link, verify, and sign in the browser. Only senders need an account.
What happens if a signer declines or does not respond?
A decline stops the envelope and notifies you. Unsigned envelopes get automatic reminders and expire after 30 days. Extend, resend or void any time.
Can I check a signed document without MirraSign?
Yes. The verifier needs no account. Drop in the sealed PDF and its manifest and the three checks run on those two files alone, reading nothing from your organisation's records, so the same check still passes years later.
How do I pay?
Card, M-Pesa, Tigo Pesa or Airtel Money. Per seat per month, in TZS.
Where is my data stored and who can see it?
Access is enforced per organisation at the database level, not only in application code. Everything is encrypted in transit with TLS 1.3, and senders can protect their own account with an authenticator app. Business plans choose data region and retention.
