After two reminder emails and no reply, a short phone call is often the next step. It is also the point where tone matters most. The customer may have forgotten, may be waiting for something or may be struggling. Your job is to make paying easy, not to make them feel small.
This guide is a conversational script for gentle payment reminders. It is not legal or compliance advice and does not describe any rule on collecting debts, which differ by country and situation. Use it for friendly reminders on ordinary invoices and subscriptions, follow your organisation's policies and check with the right colleague before using any script in a regulated setting. All names and numbers are invented.
When a call makes sense
A call works best after written reminders have gone out and the customer has not responded. It adds a personal touch where emails may have been missed, filtered or ignored. Before you dial, check:
- Has the customer already paid or replied since the last email?
- Is there an open query, complaint or dispute on the account?
- Is the amount correct and the invoice clear?
- Who is the right person to speak to?
If anything is unresolved, deal with that first.
The tone to aim for
Think of the call as a helpful check, not a demand. People who feel judged tend to avoid the next call. People who feel helped tend to sort it out.
- Use a calm, unhurried pace.
- Say what you know, plainly: the invoice number, the amount and the date.
- Ask before you assume. "Has anything got in the way?" is better than "Why haven't you paid?"
- Offer a simple route to paying, such as a payment link or a bank transfer reference.
- Agree one date and confirm it.
A five-step script
1. Identify and check you have the right person. "Hello, is that Ms Alvarez? It's Sam from Greenfield Services."
2. State the reason briefly. "I'm calling about invoice 1187 for 240, which was due on the 5th."
3. Ask what happened. "I wanted to check whether it reached you, or whether something is holding it up."
4. Offer an easy way to pay. "I can send you the payment link by email while we talk, or I can give you the bank details."
5. Agree a date and confirm. "Would Friday work for the payment? I'll send a quick email so it's in writing."
Example dialogue: forgot
You: "Hello, is that Ms Alvarez? It's Sam from Greenfield Services. I'm calling about invoice 1187 for 240, which was due on the 5th. I wanted to check whether it reached you."
Customer: "Oh no, I completely forgot. I'm sorry."
You: "No problem at all, it happens. I can send the payment link right now if that's helpful. Would you be able to pay it today or tomorrow?"
Customer: "Tomorrow morning."
You: "Perfect. I'll email the link now and note tomorrow. Thank you."
Example dialogue: waiting on something
Customer: "I'm holding off because the work wasn't finished."
You: "Thank you for telling me. Can you say what's outstanding, so I can pass it on to the team?"
Customer: "The final report is missing."
You: "I'll check on that today and call you back by the end of the day. Once the report is with you, would you be able to pay by next Wednesday?"
When there is a real query, resolve it first. Promise only what you can do, and do it.
Example dialogue: a hard situation
Customer: "Things are really tight right now. I can't pay this month."
You: "Thanks for being honest with me. I'll note that, and I'd like to see what we can do. Could I ask a colleague to talk with you about options, or would you prefer to call us when you're ready?"
Do not promise a payment plan or any concession unless you have the authority and your organisation offers it. Pass the person to the right colleague according to your process. Stay respectful and do not pressure. If you work in a regulated area, follow the specific rules and procedures set by your organisation.
What to avoid
- Blaming language. "You failed to pay" does nothing useful.
- Threats or implied consequences in a reminder call. Escalation belongs to your formal process, not your tone of voice.
- Talking to the wrong person. Share account details only with the person you are meant to speak to. Check identity as your policy requires.
- Leaving the call without a date. "Soon" invites another call.
- Not following up. A short email after the call restates the agreement.
Voicemail
Keep it brief and private. "Hello, this is Sam from Greenfield Services with a message for Ms Alvarez about her account. Please call me on 555-0100 when you can. Thank you." Avoid stating amounts or sensitive details on a message unless your policy permits.
How to practise
A calm, kind tone does not come naturally under pressure, so rehearse.
- Say the five steps aloud twice.
- Role-play a forgetful customer, a customer waiting on something and a customer in difficulty.
- Practise the sentence "Thanks for being honest with me" until it sounds genuine.
- Record yourself and listen for pace and warmth.
