Draw or type

Clients can draw their signature on screen — works with mouse, trackpad, or touch. No third-party signing tool required.

Name and date verification

The signer enters their full name and the date before submitting. Both are captured and stored with the signed proposal.

Tamper-proof record

The accepted proposal, the selected package, the signature, and the timestamp are all stored together. You have a clear record of exactly what was agreed.

PDF generated on signing

The moment a client accepts, Prosperus generates a PDF of the signed proposal and emails it to both parties. No manual follow-up needed.

Works on any device

The signature pad works on desktop, tablet, and mobile. Clients sign on whatever they have open when they finally get round to it.

No login, no friction

Clients don’t need a Prosperus account. They get a link, they read, they sign. The fewer steps between your proposal and their signature, the better.

They choose a package

If you’ve offered multiple tiers, the client selects one before signing. Single-package proposals skip this step.

They sign and submit

Name, signature, date. One screen, a few seconds. The proposal status updates to Accepted the moment they submit.

You both get the PDF

A signed PDF lands in your inbox and theirs immediately. Clean record, no chasing, no manual document generation.
