Step 1: Know your timing

The right timing is critical. Too early, and you seem aggressive. Too late, and you seem negligent. Here is the optimal schedule:

  • 1-3 days before due date — Gentle heads-up. Not a demand, just a reminder.
  • 1 day past due — Friendly follow-up. Assume the best — maybe they forgot.
  • 7 days past due — Firm but professional. Mention late fees if applicable.
  • 14 days past due — Stronger tone. Mention legal consequences if applicable.
  • 30 days past due — Formal demand. Threaten legal action if payment is not received.

PingPaid sends these automatically at the optimal time for each client, based on their payment history and your settings.

Step 2: Get the tone right

Tone is everything. The wrong tone can damage your relationship. The right tone gets you paid while preserving the relationship. Here is the progression:

Stage 1: Friendly

"Hi [Name], I hope you are doing well. Just a quick heads-up that Invoice #[Number] is due on [Date]. Let me know if you have any questions!"

Stage 2: Professional

"Hi [Name], I noticed that Invoice #[Number] for €[Amount] was due on [Date] and has not yet been paid. Please let me know if there is anything I can help with."

Stage 3: Firm

"Hi [Name], Invoice #[Number] for €[Amount] remains unpaid and is now [Days] days past due. Per our agreement, a late fee of €[Late Fee] will apply. Please arrange payment at your earliest convenience."

Stage 4: Formal

"[Name], Invoice #[Number] for €[Amount] (including late fees of €[Late Fee]) is now [Days] days past due. If payment is not received within 7 days, we will be forced to pursue formal collection procedures."

Key principle: Never be rude, never be aggressive, never be threatening. Be firm, be professional, be factual. The law is on your side — you do not need to be angry about it.

Step 3: Include the right information

Every payment reminder should include:

  • Invoice number — Unambiguous reference
  • Invoice amount — Total amount due
  • Due date — When it was originally due
  • Days overdue — How many days past due
  • Payment method — How to pay (bank details, payment link, etc.)
  • Late fee (if applicable) — Amount and legal basis
  • Consequences of non-payment — What happens next

PingPaid includes all of this automatically, with the correct legal references for your country.

Step 4: Use the right subject line

The subject line determines whether your email gets opened. Here is the progression:

  • Stage 1: "Invoice #[Number] due [Date]"
  • Stage 2: "Friendly reminder: Invoice #[Number] payment"
  • Stage 3: "Invoice #[Number] — [Days] days overdue"
  • Stage 4: "Urgent: Invoice #[Number] — [Days] days overdue"
  • Stage 5: "Final notice: Invoice #[Number] — [Days] days overdue"

Keep subject lines clear and specific. Avoid vague subjects like "Payment" or "Invoice" — they look like spam and get ignored.

Step 5: Follow up consistently

One reminder is rarely enough. Follow up consistently:

  • Send reminders at regular intervals — Every 7 days is standard
  • Escalate gradually — Tone should get firmer, not angrier
  • Document everything — Keep records of all reminders sent
  • Change channels if needed — If email does not work, try phone or certified mail
  • Know when to escalate — At 30-60 days past due, consider legal action

PingPaid automates this entire process, sending reminders at optimal intervals, escalating tone gradually, and documenting everything for legal purposes.

Step 6: Legal considerations

Payment reminders must comply with local laws. Key considerations:

  • EU countries — Late payment interest is a legal right under Directive 2011/7/EU. You must reference the directive in your reminders.
  • UK — Late payment interest is a statutory right under the Late Payment Act. You must reference the Act in your reminders.
  • US — No federal law, but state laws vary. Include your late fee policy in the contract.
  • Canada, Australia — Provincial/state laws vary. Research the specific requirements for your jurisdiction.
  • Latin America — Strong civil code protections. Reference the relevant code in your reminders.

PingPaid automatically includes the correct legal references for your country in every reminder.
