Sigi is the eSignature tool that supports every signing scenario your business needs. Sequential, parallel, self-sign, acknowledgement only, approval workflows, public embeddable forms with no login required, and scheduled future sending. One platform, every contract type.

Pick the workflow that fits the contract, configure signers and routing, send manually or schedule, track to completion across every workflow.

Pick The Workflow
Sequential for ordered signing chains. Parallel when everyone can sign at once. Self-sign for internal documents. Acknowledgement only for read-and-confirm. Approval workflows for sign-off chains. Public embeddable forms for high volume capture. Scheduled sending for timed releases. Pick the type that matches the actual contract.

Configure Once
Once the workflow type is picked, configure the specifics. Signer order for sequential. Approval chain for sign-off workflows. Required fields for public forms. Validity windows for time bound contracts. Save the configuration as a reusable template so the next contract of the same type runs without re-configuration.

Send Or Schedule
Send the contract immediately, or schedule it for a specific future date and time. Quarter end mass sending, coordinated launch contracts, time zone aware delivery. Scheduled sending handles every case where the contract needs to go out at a specific moment rather than the moment of preparation.

Track To Completion
Regardless of which workflow type the contract uses, tracking happens in one unified dashboard. Sequential progress, parallel completion percentages, approval chain status, public form submissions, all visible in the same place. The team gets a single view of every active contract.
Seven workflow types in one platform. Sequential, parallel, self-sign, acknowledgement only, approval workflows, public embeddable forms, scheduled sending. Every contract type the business runs, handled in one place.
Teams that need approval workflows often buy a separate tool for them. Teams that need public embed forms buy another. Sigi handles every signing scenario the business runs, so the team consolidates onto one platform and stops paying for multiple overlapping tools.
Some contracts need ordered signing. Counsel reviews before founder, founder before client. Other contracts need parallel signing where everyone signs at once. Both patterns are supported, picked per contract, with the right one always available.
Internal documents often need only one signature, or just a read-and-acknowledge. Self-sign handles single signer cases. Acknowledgement only confirms the document has been seen without a formal signature. Both internal workflows are first class, not workarounds.
Procurement approvals, expense sign-offs, vendor onboarding chains. Approval workflows route the document through the approval chain in the right order, with each approver signing off before the next gets notified. The chain runs automatically without manual handoffs.
Some workflows need to capture signatures from people who shouldn't have to log in. Customer waivers, event registrations, partner onboarding. Public embeddable forms accept signatures with no login required, embedded directly in the team's website or sent as a public link.
Quarter end mass sending. Coordinated launch contracts. Time zone aware delivery for international audiences. Scheduled sending handles every case where the contract needs to go out at a specific moment rather than the moment of preparation. Set it up now, send it then.

Teams running every signing workflow in one platform
Sales operations teams running quote and proposal flows. Legal operations teams running multi party agreements with sequential or parallel signing. HR teams running employment offers and policy acknowledgements. Procurement teams running approval chains for vendor onboarding. Founders running every contract type without standing up a separate tool for each. Any team whose contract mix spans more than one signing pattern and refuses to buy a different platform for each one.

All Types
Four core signing patterns handled natively. Sequential for ordered chains, parallel for simultaneous signing, self-sign for single signer cases, acknowledgement only for read-and-confirm internal documents. Pick the pattern that matches each contract.

Sequential signing, parallel signing, self-sign and acknowledgement only, approval workflows, public embeddable forms, scheduled future sending.
Documents route through signers in a defined order. Counsel reviews before founder, founder before client. Each signer gets notified only after the previous signer completes, so the chain runs cleanly without anyone signing out of turn.
All signers get notified at the same time and can sign in any order. Best for multi-party contracts where the signing order doesn't matter operationally and faster completion comes from removing the wait.
Self-sign handles single signer cases where only one person needs to execute the document. Acknowledgement only confirms the document has been seen and read without a formal signature, perfect for policy distribution and internal communications.
Documents route through approval chains where each approver signs off before the next gets notified. Procurement approvals, expense sign-offs, vendor onboarding. The chain runs automatically without manual handoffs between approvers.
Forms that accept signatures from people without requiring them to log in. Embed directly in the team's website or share as a public link. Customer waivers, event registrations, partner onboarding flows all run through public forms.
Configure the contract today, send it at a specific future date and time. Quarter end mass sending, coordinated launch contracts, time zone aware delivery. The contract goes out at the right moment without anyone having to remember.

Common questions about workflow choice, public embeddable forms, scheduled sending, mixing workflows, and connection to the other Sigi features.
Each workflow fits a specific operational pattern. Sequential for ordered signing chains where one signer must complete before the next. Parallel when signing order doesn't matter and faster completion is the goal. Self-sign for single signer documents. Acknowledgement only for read-and-confirm. Approval workflows for sign-off chains. Public embeddable forms for high volume external capture. Scheduled sending for timed releases.
