Operations & SOPs
Invoice Mailing SOP
A plain SOP for sending an invoice and chasing it. It separates the steps a person does from the steps your accounting tool should do.

The prompt
Write an invoice mailing SOP for [BUSINESS_NAME], a [BUSINESS_TYPE].
Facts:
- Accounting tool, or "none": [ACCOUNTING_TOOL]
- Who is allowed to send an invoice: [SENDER_ROLE]
- What has to be true before an invoice goes out: [READY_WHEN]
- How it is delivered: [DELIVERY] (email, mail, or both)
- Where the customer pays: [PAY_PATH]
- Reminder days, using only the numbers given: [REMINDER_DAYS]
- Who gets told if it is still unpaid after the last reminder: [ESCALATE_TO]
- What the tool already does by itself, or "nothing": [TOOL_DOES]
- What a person still does by hand: [PERSON_DOES]
Format:
1. Title, version v1.0, blank last-updated date.
2. Purpose: get a correct invoice to the customer and know the date it went.
3. Trigger: the moment [READY_WHEN] is true.
4. Steps in order. Mark each step "Person" or "Tool".
5. A "sent" definition. Sent means the customer has the invoice, not that someone meant to send it.
6. The reminder schedule from [REMINDER_DAYS] only. Do not add extra reminders.
7. The failure case: bounced email, wrong amount, or no pay path. Name [ESCALATE_TO].
8. A one-line note titled "Automate after this is true" that lists only the [TOOL_DOES] steps. If [TOOL_DOES] is "nothing", say the SOP stays manual until the tool can send and log the invoice.
Rules:
- Do not invent prices, late fees, interest, or legal threats.
- Do not invent a software feature. If [TOOL_DOES] does not name it, a person does it.
- If [ACCOUNTING_TOOL] is "none", say "the invoice tool" and do not pick QuickBooks, Xero, or any other product.
- No "just circling back". The reminder wording can be firm and plain.
