If you’re spending hours moving data between apps, chasing approvals, or nudging people to do the next step—automation can take that load off. n8n is an open-source automation tool that connects your apps and data so tasks run automatically, reliably, and on time. You don’t need to be a developer to get value: think Lego blocks for workflows.

Why automate business processes?

Automation isn’t about replacing people; it’s about removing the work that slows them down—copy-pasting, chasing approvals, retyping data, fixing avoidable errors. When you automate the repeatable parts, teams spend their time on decisions, customers, and creativity.

What changes when you automate well

  • Speed: Tasks move the moment a trigger happens—no waiting for someone’s inbox. Quotes become invoices, stock turns into POs, support tickets get the right response in seconds.
  • Quality: Fewer manual steps = fewer mistakes. Data is consistent across CRM, finance, and ops, which means cleaner reporting and better decisions.
  • Cost & capacity: The same team handles more volume without burning out. You buy time back for high-value work.
  • Resilience: Automations run on schedule, with alerts and logs. If something fails, you know where and why.
  • Governance & auditability: Every run is timestamped and traceable—who did what, using which data—so compliance conversations get easier.
  • Employee experience: People stop doing “robot work.” Morale goes up when the workday isn’t a maze of tiny tasks.

Good candidates for automation (quick sniff test)

  • The task happens 3+ times per week.
  • It has clear rules (if X, then Y).
  • It touches multiple systems (e.g., form → CRM → accounting).
  • Errors are costly or embarrassing (billing, customer comms, stock levels).
  • No one “owns” it, so it regularly slips.

Simple examples

  • New enquiry → score for fit/urgency/value → auto-book call → log to CRM.
  • Paid invoice → update revenue sheet → notify account manager → tag customer as “active.”
  • Low stock → raise purchase order → email supplier → update status for ops.

Automate these and you’ll feel the difference in a week: less firefighting, clearer numbers, and a calm, predictable flow of work.

Why n8n for business

  • Own your automations (self-host or cloud). Keep control of data, costs, and change.
  • Connect almost anything: CRMs, finance tools, spreadsheets, email, Slack/Teams, webhooks, databases.
  • Build once, reuse often: drag-and-drop logic, schedules, approvals, error handling.
  • Audit friendly: every run is logged—who/what/when—so governance and troubleshooting are simple.

Three copy-and-adapt examples

1) Finance — Daily cash position + alerting

Outcome: Each morning finance leaders get a single message showing cash in/out and whether today’s balance is above your “safe” threshold.

You’ll need: Read access to bank data (API or CSV export), a Google Sheet (or DB) to log, Slack/Email for alerts.

Build it in n8n (simple, no-jargon steps)

  1. Trigger → add a Cron node to run at 7:00 AM.
  2. Get balances → use HTTP Request to your bank API (or IMAP Email node to pull last CSV statement).
  3. Parse → if CSV, add Spreadsheet File node to read totals; if API, skip parsing.
  4. Compare to threshold → add IF node: “Is balance < SAFE_LIMIT?”
  5. Notify
    • If YES → Slack (or Email) node: “Balance $X. Today’s outgoings $Y. Action: pause non-critical spend / confirm receivables.”
    • If NO → send a short “All good” summary.
  6. Log → Google Sheets (or Postgres/MySQL) node to append date, balance, inflow/outflow, and alert status.
  7. (Optional) Escalate → IF node: “If below CRITICAL_LIMIT, @CFO + @AP Lead.”

Why it helps: Less inbox-digging, earlier visibility of risk, simple audit trail.

2) Accounting — Auto-create and send invoices from a form

Outcome: When a client submits a work-order form, an invoice is created in your accounting system, emailed to the client, and tracked—no manual typing.

You’ll need: A client form (Typeform/Google Form), accounting app (Xero/QuickBooks), and your email tool.

Build it in n8n

  1. Trigger → Webhook node (or Typeform/Google Forms trigger) to receive new submissions.
  2. Clean & map → Set node to standardise fields (Client Name, Email, Item(s), Qty, Price, Due Date, Tax).
  3. Create invoice
    • Use Xero (or QuickBooks Online) node: “Create Invoice” with mapped fields.
    • Capture the invoice number/URL from the node’s output.
  4. Send to client → Email node: attach PDF (from accounting node) and a friendly message with payment link.
  5. Notify team → Slack/Teams node to #billing with client name, amount, due date, and invoice link.
  6. Record → Google Sheets/DB node to log invoice ID, client, amount, due date, status “Sent”.
  7. (Optional) Reminders → a Cron node + Xero/QBO “Get Invoice Status”: if unpaid after X days, send polite reminder.

Why it helps: Fewer errors, faster cash cycle, status always visible.

3) Manufacturing — Low-stock → auto purchase order

Outcome: When a part drops below its minimum level, a purchase order is generated and sent to the supplier; the rest of the team is notified.

You’ll need: Inventory table (Sheet/ERP/DB), supplier email, and a PO template.

Build it in n8n

  1. Trigger → Cron node to run every hour (or connect to your ERP’s webhook on stock change).
  2. Read inventory → Google Sheets/DB node: fetch items where OnHand < MinLevel.
  3. For each item → Split In Batches node to loop through items that need re-order.
  4. Create PO
    • Spreadsheet File or HTML Template node to fill a simple PO (Item, Qty to Order, SKU, Delivery Address, Reference).
    • Export as PDF (use HTTP Request to a lightweight HTML-to-PDF service if needed).
  5. Email supplier → Email node with the PDF attached and “Please confirm delivery date.”
  6. Notify ops → Slack/Teams node with the PO summary.
  7. Update records → Google Sheets/DB node: set ReorderStatus = “PO Sent” and store the PO number/date.

Why it helps: Fewer line-stoppages, faster re-orders, clean trail for audits.

Tips that keep automations healthy

  • Start tiny, then stack: ship a 1-screen workflow first; add branches only after it runs cleanly for a week.
  • Name clearly: “FIN-Cash-7am” beats “workflow-2.” Future-you will thank you.
  • Fail safely: always include a catch path—if a step fails, notify a human and log the details.
  • Document in the workflow: add Notes nodes (“What this does / Owner / Last updated”).
  • Measure outcomes, not just runs: e.g., “late-payment reminders cut DSO by 5 days.”

Quick starter checklist

  • n8n Cloud or self-hosted instance running
  • Service accounts/API keys for apps you’ll connect
  • A shared inbox or Slack channel for alerts
  • One small, valuable use case (pick from the three above)
  • A clear owner (even if it’s you) to review logs weekly

Want a downloadable template?

Tell me which example you’re starting with (Finance / Accounting / Manufacturing) and I’ll give you:

  • A .json export of the n8n workflow
  • A plug-and-play Google Sheet (where relevant)
  • A tested email/Slack message template

You’ll be live in an afternoon—and you’ll never chase that task again.
