How to chase an unpaid invoice without losing the customer

Chase an unpaid invoice by checking the balance first, sending a clear reminder and recording the customer’s response. Keep disputed work, a missing invoice and an overdue payment as different problems. A repeated message cannot resolve an incorrect bill.

Explore the wider invoicing and getting paid guides for the steps around this decision.

Check before contacting the customer

Check	Why
Correct customer and invoice	Avoid chasing the wrong work
Invoice delivered	A customer may not have received it
Agreed due date	A bill is not overdue before that date
Payments and credits	The remaining balance may differ from the original total
Dispute or query	Address the issue rather than repeating the demand

Keep the invoice reference, due date, balance and payment method in the message. If a payment has just arrived, reconcile it before sending another reminder.

A proportionate follow-up ladder

Start with a neutral check that the invoice was received. Follow with a clear request for payment or an explanation of any issue. If the customer proposes a payment arrangement, record what was actually agreed and track the balance. Escalate unresolved or disputed debts through appropriate advice rather than making unsupported legal threats.

For an illustrative invoice of EUR 600 with EUR 200 already paid, chase the EUR 400 balance, not EUR 600. If the customer disputes a separate extra, identify that line and its confirmation record instead of treating the whole conversation as refusal to pay.

Keep household and business rules separate

Irish statutory late-payment interest and recovery compensation concern qualifying commercial transactions, not ordinary household customer bills. A reminder template should not automatically add those charges to every overdue invoice. Check the applicable agreement and current primary guidance for the customer type.

JobDiary supports invoice, part-payment and optional overdue reminder records. The business still needs to verify the invoice, choose suitable wording and respond to queries. Software should keep the facts straight rather than make a payment dispute disappear from view.
