Resumable Form-Intake Pipeline — n8n + Postgres + CR, zero lost submissions

About this Gig

I'll build a resumable form-intake pipeline that doesn't lose submissions. Your forms POST to n8n, n8n writes to Postgres FIRST (before any external call), then fans out to your CRM. A queue-processor sweep catches any failed nodes and retries with exponential backoff. Three-layer durability pattern (documented as binding doctrine across my own stack): - Layer 1: Front-end Brevo fallback if the primary POST fails - Layer 2: Postgres-first INSERT before any downstream call - Layer 3: Per-step state row + queue-processor retry sweep Typical scope: 1-3 forms (lead-gen / partner-application / customer-intake), CRM integration (HubSpot / GoHighLevel / Salesforce / Brevo), Postgres state schema, queue-processor workflow, optional ops dashboard. Stack: n8n (self-hosted or cloud), PostgreSQL or Supabase, HubSpot / Brevo / similar CRM, webhook orchestration. Deliverables: - Workflows live in your n8n instance - Postgres schema + migration scripts - Per-form runbook - Hand-off video walkthrough Production track record: 3 production forms running this exact pattern across my own ventures. Zero submissions lost in 4 months.

Requirements

From you to start: - Forms list: which 1-3 forms you want migrated or built fresh - CRM stack: destination CRM (HubSpot / GoHighLevel / Salesforce / Brevo / similar) - Sample submissions: 5-10 example payloads per form (anonymised if needed) - Hosting: do you have a Postgres or Supabase already? Where's your n8n hosted? - Access: 30-min kickoff call plus async daily check-ins
