The invoice is due.
Ask for the date.
Send a clear overdue-invoice reminder with the invoice, outstanding amount and one question the client can answer. Keep the tone useful and the record current.
Connect Gmail to get started. You approve each money action.
Confirm the invoice is still unpaid, attach it or link to the existing payment route, and ask the client to confirm a payment date. If something is blocking approval, ask what is missing and who owns the next step.

Check the balance and the recipient.
Review the invoice, due date and payment records. Deduct any payment or credit already received through your normal reconciliation process. Check the latest email thread so you do not ask a client for money they just sent.
Confirm the message is going to the person who can handle billing. If the project contact and accounts-payable contact differ, ask who owns payment rather than sending repeated reminders to someone who cannot act.
Make the request easy to answer.
Name the invoice and amount in the subject or opening line. Keep the invoice and existing payment instructions accessible. Ask for a date or the missing approval detail rather than only saying the invoice is overdue.
Subject: Payment date for invoice [number] Hi [name], invoice [number] for [outstanding amount] was due on [date]. I’ve attached it again for convenience. Could you confirm the planned payment date? If approval is waiting on anything from us, please let me know what is needed.
Turn the response into a specific next step.
If the client names a date, record it and follow up after checking whether the payment arrived. If they need a purchase order or revised billing detail, send the requested information and ask them to confirm receipt.
If they dispute the invoice, route the issue to the person who can resolve the scope or pricing question. Keep the disputed amount and any undisputed balance clear. Sending the same reminder without addressing the reply will not remove the blocker.
Follow up with context, not a longer accusation.
Choose a follow-up date appropriate to the relationship and the invoice. Reference the earlier message and ask one question. Avoid adding unagreed fees or threatening an action the business has not decided to take.
Hi [name], following up on invoice [number], with [balance] still showing outstanding in our records. Could you confirm the payment date or connect me with the person handling approval? Please let me know if a payment has already been sent so we can match it.

A few things
before you act.
How often should I send reminders?
Set a cadence that fits the agreement and relationship. Check replies and payment records before each follow-up instead of sending on a rigid schedule regardless of context.
Should I add a late fee in the email?
Do not invent new payment terms in a reminder. Follow the business’s existing agreement and review process.
Does Huck collect the payment?
No. Huck finds overdue client invoices in Gmail and sends approved reminders. The client pays through your existing payment route.
