Items below it go through automatically or with a light check, and items above it wait for a named person to approve. The limit is usually a dollar amount, such as invoices over $1,000, but it can also be a risk level, such as any message to a client.

A threshold lets the routine items move and spends human attention where the money or risk is. It is the clearest example of keeping a [human in the loop](https://learn.ynteractive.com/content/glossary/human-in-the-loop) without slowing everything down. In an automated [approval workflow](https://learn.ynteractive.com/content/glossary/approval-workflow), the rule is written into the flow, so the same limit applies every time and each decision is recorded. Related controls include [invoice approval](https://learn.ynteractive.com/content/glossary/invoice-approval) and an [audit trail](https://learn.ynteractive.com/content/glossary/audit-trail). ## In a real lesson: Invoices from Your Inbox to Google Sheets, with Approval In the [Invoices from Your Inbox to Google Sheets, with Approval lesson](https://learn.ynteractive.com/content/invoice-inbox-to-google-sheets-approval-n8n), the threshold is $1,000. You are keeping the books at Cobalt Street Architects, a made-up firm, and every invoice from a vendor such as Tidewater Office Supply is logged in a sheet automatically. An If node checks the total. Anything over $1,000 is emailed to the owner with an Approve button through Gmail's Send message and wait for response. Smaller invoices are logged without interrupting anyone. The number is the lesson's example, so set your own to match your risk.

A threshold is the point at which someone must approve. You can have a threshold within a budget. ### Threshold vs blanket approval A blanket approval lets a category through without review. A threshold only lets through items under a limit. ## Tips - Choose a limit by asking what loss you could absorb without anyone noticing. - Name the approver and a backup so items do not stall. - Review the limit each quarter and keep a record of every approval. ## Related terms [Approval workflow](https://learn.ynteractive.com/content/glossary/approval-workflow) · [Invoice approval](https://learn.ynteractive.com/content/glossary/invoice-approval) · [Human in the loop](https://learn.ynteractive.com/content/glossary/human-in-the-loop) · [Audit trail](https://learn.ynteractive.com/content/glossary/audit-trail) · [IF node](https://learn.ynteractive.com/content/glossary/if-node) ## More Business terms [AR aging report](https://learn.ynteractive.com/content/glossary/ar-aging-report) · [Attorney-client privilege](https://learn.ynteractive.com/content/glossary/attorney-client-privilege) · [Audience segmentation](https://learn.ynteractive.com/content/glossary/audience-segmentation) · [Autoresponder](https://learn.ynteractive.com/content/glossary/autoresponder) ## Where you use it: free lessons - [Invoices from Your Inbox to Google Sheets, with Approval](https://learn.ynteractive.com/content/invoice-inbox-to-google-sheets-approval-n8n) (n8n, 14 min) - [Prompt Chaining for a Client Campaign Plan: Build It in Steps with ChatGPT (Agencies)](https://learn.ynteractive.com/content/prompt-chaining-client-campaign-plan-agency) (ChatGPT, 7 min) ## Prompt templates that use it [Invoice approval request email prompt](https://learn.ynteractive.com/content/prompts/invoice-approval-request-email-prompt) ## Frequently asked questions **What is a good invoice approval threshold?** It depends on your size and risk. Many small firms start with a round figure that matches a loss they could not easily absorb, then adjust. **Can AI approve invoices?** AI can read and log them, but a person should approve anything above your threshold, especially where money leaves the account. **Where do I set an approval threshold in n8n?** Use an If node on the total, as in the lesson, and send the large invoices to an approval email and wait for the answer.
