Documents & E-signature

Send proposals & contracts that get signed in minutes

Build proposals, estimates, and contracts from templates, send them for legally-binding e-signature, and auto-invoice the moment they're signed.

No credit card · 20-min setup walkthrough

Tetherlo turns proposals and contracts into something prospects can review and sign from their phone in minutes. Build estimates, proposals, and agreements from reusable templates, send them for legally-binding e-signature with a complete audit trail, and collect signatures from every recipient who needs to sign. Add fillable fields to PDFs you already use, watch when each document is opened and signed, and auto-generate an invoice the second the last signature lands — all logged to the contact so nothing falls through the cracks.

How it works

From template to signed and billed

01description

Build from reusable templates

Create a proposal, estimate, or contract once, save it as a template, and reuse it for every new deal. Merge contact details automatically so each document is personalized without re-typing — your team sends consistent, on-brand paperwork in seconds instead of starting from a blank page.

  • Reusable proposal, estimate, and contract templates
  • Auto-merge contact details into every send
  • Consistent, on-brand documents in seconds

Sign legally, with an audit trail

Send documents for legally-binding e-signature and let recipients sign on any device. Every action is captured in a full audit trail — who opened it, when they signed, and from where — so you have a defensible record of consent without printing, scanning, or chasing a wet signature.

  • Legally-binding e-signatures on any device
  • Full audit trail of opens and signatures
  • Defensible record of consent on every deal

Auto-invoice the moment it's signed

The instant a document is signed, Tetherlo can generate the matching invoice automatically — no manual handoff, no delay between yes and getting paid. Track each document's status from sent to viewed to signed, all tied to the contact record so billing and pipeline stay in sync.

  • Invoice generated automatically on signature
  • No gap between signed and billed
  • Sent, viewed, and signed status on every document

Documents FAQ

Documents & e-signature — your questions

Are the signatures legally binding?

Yes. Documents sent through Tetherlo are signed with legally-binding e-signatures, and every signature is backed by a full audit trail recording who opened the document, when they signed, and from where. That gives you a defensible record of consent without printing, scanning, or collecting a wet signature.

Can I reuse templates?

Absolutely. Build a proposal, estimate, or contract once and save it as a reusable template. Contact details merge in automatically on each send, so your team produces personalized, on-brand documents in seconds instead of rebuilding paperwork for every deal.

Does it invoice automatically after signing?

It can. The moment a document is signed, Tetherlo can generate the matching invoice automatically — closing the gap between getting a yes and getting paid. You can also track each document from sent to viewed to signed, all logged to the contact record.
