n8n workflow template

n8n proposal generation and e-signature template

This n8n proposal and e-signature template prices a deal exactly in cents, sends the proposal for signature through DocuSeal using your own template, and keeps the status right automatically: viewed, signed, declined or expired, with a Slack alert on the final ones.

What this workflow does

  1. Receives the deal details, validates every field, and rejects unauthorised or malformed requests
  2. Prices the proposal in whole cents with no rounding drift, adds tax, and assigns a proposal number and a valid-until date
  3. Sends it for signature through DocuSeal using your template and records it in the Proposals sheet
  4. Retries are safe: the same deal never creates two proposals, and a half-finished attempt is resumed, not duplicated
  5. A second webhook receives DocuSeal events and keeps the status current, alerting Slack when a proposal is signed, declined or expires

If something fails

  • Every step retries three times automatically
  • The proposal is recorded as pending before DocuSeal is called, and DocuSeal is checked for an existing request first, so a retry never sends a second proposal
  • On persistent failure the raw request is saved to an Errors sheet and your team is alerted in Slack. DocuSeal retries failed webhook deliveries for up to 48 hours

What it costs to run

ItemCost
n8n (self-hosted)Free software plus roughly $5 to $7 per month for a small server.
n8n Cloud StarterRoughly $20 to $24 per month for 2,500 executions.
DocuSealAPI access needs DocuSeal Pro, about $20 per user per month, plus about $0.20 per document signed through the API. Checked October 2026.
Google Sheets and Slack$0 on free plans.

Each proposal uses roughly three to five n8n executions in total: one to create it and one for each DocuSeal event you subscribe to. If you self-host DocuSeal, confirm with DocuSeal which plan unlocks the API.

Who it is for

Useful for agencies, consultants and contractors who send proposals by hand today and want signing, tracking and follow-up handled automatically. A Make version is coming soon.

Why a Conviq template

Each template is built to a production standard: failure handling is real, every cost is listed before you buy, and nothing ships with credentials. Browse all n8n workflow templates, learn about our n8n automation services, or have us tailor one as a custom automation project.

Frequently asked questions

Do I need a DocuSeal account?
Yes. You create a proposal template in DocuSeal with a few named fields, and the workflow fills it in. The setup guide lists the exact field names.
What stops it sending the same proposal twice?
Each deal gets a fixed proposal number before anything is sent, and DocuSeal is checked for that number first, so retries resume instead of repeating.
Is there a Make version?
A Make version is coming soon. The n8n version is available now.
