## Messages to send Mindie
- On the due date: "Remind me on 15 November at 10am to check if Acme has paid invoice 104"
- A polite chase a week later: "Remind me on 22 November at 10am to chase Acme for invoice 104 if it's still unpaid"
- Monthly invoicing: "On the 1st of every month at 9am remind me to send invoices to all retainer clients"

An invoice follow-up reminder on WhatsApp is a message on the due date, and again after it, that prompts you to check whether a client has paid. With Mindie, send "remind me on 15 November at 10am to check if Acme has paid invoice 104" when you send the invoice, and add a second one for a week later.

For freelancers and small businesses, the problem is rarely that clients refuse to pay. It's that nobody notices the payment is late until a month has gone by, and by then chasing it feels awkward.

## When to set it

- **When you send the invoice.** You know the due date then.
- **On the due date,** to check if it arrived.
- **A week after,** for a polite chase if it hasn't.
- **Monthly,** a reminder to send invoices at all, if you bill retainers.

## Why invoices go unpaid

- **Nobody owns the chase.** Sending the invoice feels like the end of the job.
- **Chasing feels awkward,** so it gets put off.
- **Due dates are scattered.** Different clients, different terms, different dates.

## Habits that get you paid sooner

- **Keep an unpaid invoices list.** Ask Mindie to keep the list; add each invoice with amount and due date, and remove it when paid.
- **Chase early and politely.** A short message on the due date gets a better response than a frustrated one six weeks later.
- **Note each client's payment terms.** "Acme pays net 30, accounts email is…" saves looking it up.

## How Mindie handles it

1. **Send the reminders when you invoice,** with the client, invoice number and dates.
2. **Mindie confirms** each one and messages you on the day.
3. **When the money arrives,** delete the follow-up by name, or ask Mindie to remove it from your list.

## What Mindie doesn't do

- **It doesn't message clients** or send invoices.
- **It doesn't connect to your bank or accounting software,** so it can't see if you've been paid.
- **It isn't legal or financial advice.**

## FAQ

### Does Mindie send payment reminders to my clients?
No. Mindie reminds you to chase the payment. The message to the client is sent by you.

### Can I keep a list of unpaid invoices?
Yes. Ask Mindie to keep a list called unpaid invoices, add each one with the amount and due date, and remove them as they're paid.

### What should a polite payment reminder say?
Keep it short and factual: the invoice number, amount, due date and how to pay. Most late payments are oversights, so assume good faith first.

### When should I set the reminder?
Set it when you send the invoice, for the due date or a day after. Add a second one a week later if you might need to chase again.

### Can I set it from a screenshot of the invoice?
Yes. Send it, and Mindie reads the date and amount and checks them with you. You still send the message to your client.
