From PDF to signed in three steps.

No rebuilding forms from scratch. Upload, refine, and send.

01

Upload your PDF

Drop in any contract, form, or agreement. Signum reads the page structure and existing fields automatically.

02

Refine in seconds

Auto-detect underlines and boxes, adjust field types, sizes, and assignees in the precise visual editor.

03

Send & track

Share a secure link, collect signatures and responses, and download the completed PDF with a full audit trail.

Everything you need to run paperwork end-to-end.

Signum handles the whole life of a document — from first upload to signed, filed, and audited.

Upload any PDF

Import existing forms, contracts, or scanned documents. Signum preserves the original layout and reads native AcroForm fields.

Auto-detect fields

AI-powered detection finds underlines, checkboxes, signature blocks, and dates — even on scanned or image-based PDFs.

Precision field editor

Drag, resize, and fine-tune every field with coordinate-accurate placement. Text aligns to the baseline so filled forms look professional.

Multi-party signing

Assign fields to specific signers, set signing order, and reuse signer profiles. Everyone knows exactly what to fill.

Collect payments on signing

Charge clients at the moment they sign with Stripe Connect. Funds settle directly in your account — no per-signature fees.

Fill from a photo

Snap a paper form and Signum maps the answers into your fillable PDF, saving time on manual data entry.

Templates & folders

Save any document as a reusable template. Organize forms, contracts, and client files in shared workspace folders.

Audit-ready certificates

Every completed signature generates a tamper-evident audit trail PDF with timestamps, signer identity, and document DNA.

Secure by default

Organization-based access controls, private storage, expiring recipient links, and row-level security keep client data safe.

Built for teams that live in paperwork.

Whether you send ten forms a month or ten thousand, Signum keeps the process consistent and compliant.

Legal & contracts

Retainers, engagement letters, NDAs, and fee agreements with client-specific fields.

HR & onboarding

Offer letters, I-9s, handbook acknowledgments, and benefits forms routed to the right people.

Sales & proposals

Quotes, order forms, and SOWs that collect signatures and payments in one flow.

Accounting & tax

Engagement letters, intake forms, and authorization documents sent during tax season.

Enterprise-ready security

Client data stays protected.

Security isn't an afterthought. Signum is built with workspace isolation, audit logging, and privacy-by-design controls.

SOC 2-aligned infrastructure on Lovable Cloud

End-to-end encryption in transit and at rest

Granular workspace permissions and audit logs
