Legally-Clear Contracts. Without the Faff.
Send a service agreement, get it signed online, and keep a tamper-evident record — all from within Experi. Protects you before the work starts, so you can invoice with confidence when it ends.
Protect Your Work TodaySigned Agreements Before You Start Work
Experi's service agreements use OTP (one-time password) signing — no DocuSign account, no PDFs emailed back and forth. Your client clicks the link, reviews the terms, enters a code sent to their phone, and signs. You get a tamper-evident audit trail and a signed PDF certificate.
Key Benefits
Tamper-Evident Audit Trail
Every signed agreement is locked with a cryptographic hash. Any attempt to alter the document after signing is immediately detectable. Admissible as evidence.
OTP Signing — No DocuSign Needed
Clients sign via a one-time password sent to their phone or email. No accounts to create, no software to install. They just click the link and sign.
PDF Certificate
Once signed, Experi generates a PDF certificate showing the agreed terms, signer details, timestamps, and verification hash. Download and keep forever.
How It Works
Create Your Agreement
Write your service terms in Experi, or use a template. Add project scope, payment terms, IP rights, revision limits — whatever protects you.
Send for Signature
Enter the client's email. They receive a secure link with the agreement. They review, then enter the OTP sent to their phone or email to sign.
Get the Signed Certificate
Experi creates a tamper-evident PDF certificate. Both parties receive a copy. The audit trail is stored securely in your account.

View Pricing DetailsFrequently Asked Questions
Is OTP signing legally valid in the UK?
Yes. Under the Electronic Communications Act 2000 and eIDAS regulations, electronic signatures are legally valid in the UK. An OTP combined with a tamper-evident audit trail is considered a reliable form of electronic signature.
What if the client refuses to sign?
That's a business decision, not a software one. Having the signed agreement before you start work is the protection. If they won't sign, you can decide whether to proceed.
Can I use my own contract terms?
Yes. You write the content of the agreement — Experi handles the signing infrastructure, audit trail, and certificate generation.
