Service event log

One job. One agreed version. A record both sides can find later.

Start without a cardThree welcome records are included.

Pay only after sealingDrafts and failed seals consume no record usage.

Get the result automaticallyBoth parties receive the final PDF after both sign.

The work is finished. The handover is scattered.

Photos stay in camera rolls

The client has some, you have others, and nobody knows which belong to the final version.

Agreement disappears

A clear conversation on site becomes difficult to prove when the invoice arrives.

Finding proof becomes another job

Messages, PDFs and signatures sit in different apps when you need one clean record.

Close the job while it is still clear.

Designed for the phone already in your pocket. Your customer needs only the private email link.

  1. Prepare

    Add the agreed work

    Choose the customer, describe the revision and add photos, documents, pricing and notes.

  2. Sign

    Both people confirm it

    You sign first. The customer reviews the same frozen revision and signs from the email link.

  3. Keep

    Receive the shared record

    SignThatUp seals the record, emails the final PDF to both sides and opens the private customer room.

The whole handover stays together.

Photos and documents

Keep original images, PDFs and the files that define what was delivered.

Scope, price and notes

Record the proposal, agreed range, exceptions and the details both people are reviewing.

Electronic or wet-ink

Use email-invited electronic signing or add a wet-ink signature photo to the exact revision.

A result both sides keep

After both signatures, each side receives the final PDF and private access to the sealed record.

Proof is a process, not a badge.

We show the controls that exist today and name the assurance that does not.

See the security boundary
Original files
Private evidence bytes are identified by cryptographic hashes.
Signed content
Both people attest to the same frozen content hash.
Public verification
The public surface is PII-minimal. Private content needs private access.
Workspace access
Authentication identifies the user; server-side membership decides the workspace.
Assurance boundary
Lite uses service event time, not an independent qualified timestamp.

Use it by hand today. Integrate it when ready.

Prepare records through the REST API, MCP tools or signed webhooks. Every signature still belongs to a human.

Read integration docs
REST v1

Prepare job records

Create scoped drafts, attach evidence and read status from your own system.

MCP

Give agents narrow tools

Automate repetitive preparation without giving software signing authority.

Webhooks

Follow the lifecycle

Receive signed, retryable events as signatures and records move forward.

Useful today. Clear about what comes next.

Secure your account, then continue directly to Stripe.

The first 100 paying workspaces share one founder pool. After it fills, Stripe shows €19/month or €190/year before payment. The discount covers the Pro base subscription, not overages or future third-party assurance fees. Yearly overages are settled at renewal. Cancellation ends founder eligibility. VAT is not charged while the provider is not identified for VAT purposes.

The SignThatUp promise

Clear limits. No hostage records.

Your client never pays us. Signing a record does not create a client subscription.

Your sealed history stays visible. Cancelling Pro does not erase already sealed records.

Help stays inside the workspace. Open a private support thread without granting support access to your jobs or evidence.

Straight answers before the first job.

Does my client need an account?

No. The client receives a private email link, reviews the frozen job revision and signs without an account or SignThatUp subscription.

What happens after both people sign?

SignThatUp seals the exact revision, emails the same final PDF to both parties and gives the customer private access to the sealed record room.

Is this a legally qualified electronic signature?

Not in Lite. Lite records an email-invited electronic signature or wet-ink signature photo with the frozen content and service events. Advanced and qualified assurance will be optional, separately priced upgrades.

Can I change a record after the client signs?

No. A signed revision is frozen. If the work changes, create a new revision so the earlier agreement remains understandable.

What happens after the first 100 Pro customers?

Founder pricing closes automatically. New customers see the regular €19 monthly or €190 yearly price in Stripe before paying. Existing continuously subscribed founders keep their discount for 24 months.

Your next handover can be the clear one

Good work deserves a clear ending.

Create a workspace, add the job and send one signing link.
