Frequently asked questions

What counts as an envelope?
An envelope is a single document sent for signature. One envelope can have unlimited signers. If you send a contract to 5 people to sign in order, that's 1 envelope.
Do signers need an account?
No. Signers can review and sign documents via a public link without creating an account. Only the sender (you) needs an account.
Can I switch plans later?
Yes. Upgrade at any time to get immediate access to more envelopes and seats. Downgrades take effect at the end of your current annual billing cycle.
What happens if I exceed my envelope limit?
On the Free plan, you'll receive a warning at 80% usage. At 100%, you'll need to wait for the next year or upgrade to Solo. Paid plans have hard limits of 900 (Solo) or 3,600 (Growth) documents per year. Your existing envelopes continue normally.
How do user seats work?
Unlike traditional 'per-seat' pricing, IUSign provides an organizational bucket. Solo plans include up to 20 team members at a flat rate. Growth plans include up to 50 members. This allows your team to scale without worrying about individual monthly seat costs.
What is the Global Sending Limit?
The Global Sending Limit is the total number of documents your entire organization can send in a year, including both individual sends and Bulk Sends. Solo plans can send up to 900 documents per year; Growth plans get 3,600. Limits reset annually from your plan purchase date.
Is my data secure?
Every signature is cryptographically hashed with SHA-256. Audit logs are stored in an immutable database — even administrators cannot delete or modify them. All data is encrypted in transit (HTTPS) and passwords are bcrypt-hashed.
What is white-label branding?
White-label lets you replace all IUSign branding with your own — logo, colors, organization name, custom domain (sign.yourcompany.com), and branded emails. Everything looks like it comes from your company, not ours.
Do you offer a free trial for paid plans?
Yes. Both Solo and Growth plans include a full 14-day free trial. No credit card required. You get 14 days to explore all features including Bulk Send and custom branding.
Can I cancel anytime?
You can cancel your annual subscription at any time. You will maintain access until the end of your current 12-month period. We also offer a 30-day money-back guarantee for new annual subscribers.
