Most e-signature projects stop at “send”. The value is in what happens next — the contract raised, the invoice issued, the deal stage moved, the onboarding started — automatically, the moment the document is signed. We build the whole chain: the data that fills the document, the platform that signs it, and the systems that react to it.

## What it does

Generates agreements from your own data, routes them for electronic signature, and drives every downstream action the moment they are signed — on DocuSeal, DocuSign or PandaDoc, orchestrated in n8n.

## Where it creates value

The gate between selling and getting paid. Quote, proposal, contract and invoice run as one continuous chain: signature is the event that closes the sale and opens the delivery and billing stages behind it.

## Why it cannot be ignored

Signature is usually the longest queue in quote-to-cash, and it is a queue of deals you have already won. Every day a document sits unsigned is revenue deferred on work that is already agreed — and every agreement retyped by hand is a chance for the contract to disagree with the quote it came from.

## What you get

- **Built from your data, not retyped** — The agreement is generated from the quote, the CRM record or the job. Price, scope, term and client details cannot drift from the source, because there is only one source.
- **Signed means something happens** — The signed event is captured and acted on — contract created, invoice raised, deal stage moved, onboarding started, the signed copy filed where it belongs. Nobody chases it, nobody copies it across.
- **Chasing that runs itself** — Reminders, escalation and expiry on a schedule you set, with one live view of every document out for signature and how long it has been sitting there.
- **An audit trail you can produce** — Who signed, when, from where, and against which version — held with the document and queryable, so a dispute or an audit is answered in minutes rather than a search through inboxes.
- **Your platform, your process, no lock-in** — DocuSeal, DocuSign or PandaDoc, chosen on your volume, your counterparties and your data-residency rules. The orchestration sits in n8n and belongs to you, so changing platform later does not mean rebuilding the process.

## The five documents that decide when you get paid.

- **Quotes** — Priced and issued from the CRM or job record, then accepted with a signature rather than an email saying yes. An accepted quote becomes a contract and an invoice on its own. Nothing is priced twice, and nothing is billed from memory.
- **Proposals** — Scope, pricing and terms assembled from the same source as the quote and sent as one signable document — with pricing tables and options where the proposal is doing the selling. The proposal stops being a PDF somebody has to chase and becomes the moment the deal closes.
- **Contracts** — Master agreement, statement of work and data processing agreement issued as one pack, countersigned, versioned and filed against the client record. Delivery can start the day it is signed, because every system behind it already knows that it was.
- **NDAs** — Issued automatically when a meeting is booked, signed before the call, filed against the company without anyone touching it. Turns a two-day email exchange into a step in the booking, so the first conversation is the real one.
- **Change requests** — A variation raised against the original contract, priced, signed, and added to the billing schedule and the delivery plan together. Unsigned variations are the most common cause of delivered work that never gets invoiced.

## Not every signature is equal — and not everything can be signed electronically.

- **Simple Electronic Signature (SES)** — A typed name, a drawn signature or a click, accepted as evidence of intent to sign. Valid in the UK under the Electronic Communications Act 2000. Everyday commercial agreements — proposals, quotes, NDAs, purchase orders, job sheets — where identity is already established by the relationship.
- **Advanced Electronic Signature (AES)** — A signature uniquely linked to the signatory and to the document, so any change made afterwards is detectable. Higher-value or regulated agreements, where you need to prove who signed and that the document has not moved since.
- **Qualified Electronic Signature (QES)** — An advanced signature plus an identity check by a qualified trust service provider — the strongest standing under UK eIDAS. Where the law or the counterparty asks for the electronic equivalent of a witnessed wet signature.
- **What still cannot be signed electronically** — Wills, most land transactions and certain consumer credit agreements sit outside electronic signature in the UK. Deeds can usually be executed electronically but still require a witness. So the exceptions are designed into the process from the start, rather than discovered at the point of signing.
- **The signed-event receiver** — The component that turns “document signed” from an email notification into a recorded state change your systems can act on. Without it, a document can be fully signed while your CRM, your finance system and your delivery team still show it as sent. It is the single most common failure in e-signature projects, and it is invisible until someone asks why the invoice was never raised.
