The Invoice Is Forty Days Old and a Fixed Sequence Beats an Awkward Phone Call

A small contractor finishes a job in June, invoices it, and by the second week of August has been paid for everything except one account that has gone quiet. What usually happens next is nothing for another fortnight, followed by a phone call made while irritated, which produces either an apology and a payment or a defensive conversation that damages the relationship without producing the money. There is a better way to run this and it is not a matter of firmness. It is a matter of having a fixed sequence that applies to everybody, so that no individual step is a judgment about the customer.

Before Anything Else, Make the Invoice Easy to Pay

A meaningful share of late payment is administrative rather than deliberate, and the cheapest collection work happens before anything is owed. An invoice should go out the day the work is finished rather than at month end, should name a due date rather than terms somebody has to interpret, should carry a reference the customer's own system can match, and should offer a way to pay that takes under a minute. Where a business is invoicing another business, find out at the outset who processes payments and what they need on the document, since an invoice missing a purchase order number sits in a queue for a month and nobody tells you.

The Day After Due, Which Should Not Be a Decision

An automated reminder goes out the day after the due date, generated by whatever system produced the invoice, worded neutrally, and attaching the invoice again. This is not a chase and should not read as one. Its value is that it happens without anybody deciding to do it, which removes the emotional cost of the first contact entirely, and a genuine proportion of overdue invoices are settled at this stage by somebody who simply had not seen it.

A Week Later, a Short Personal Message

At around a week past due, send a brief message from a person rather than a system. Three sentences: the invoice number and amount, a note that it appears unpaid, and a question asking whether there is anything they need in order to process it. That last question is the important one, because it converts a demand into an offer of help and it frequently produces the actual answer, which is often that the document is missing something, that the person who approves it has been away, or that there is a query about the work nobody mentioned. Every one of those is fixable in an afternoon once it has been said out loud.

Two Weeks Past Due, a Telephone Call

Written messages can be deferred indefinitely and calls cannot, which is why the call belongs in the sequence rather than at the end of it. Call the person who actually processes payments rather than the person who hired you, be pleasant, and ask two questions: is the invoice approved, and when is it scheduled to be paid. Then write down what you were told and send a short message confirming it. That confirmation is doing two jobs, giving the customer a record of a commitment they made and giving you a dated document if the commitment is not kept.

Thirty Days Past Due, a Formal Letter With a Date

At a month overdue the tone changes once, deliberately, and then does not change again. A short formal letter states the amount, the original due date, the previous contacts by date, and a specific date by which payment is required, along with what will follow if it passes: a formal demand, a claim in small claims court, referral to a collection agency, or a lien where the work and the jurisdiction allow one. Keep it factual and unemotional, send it by a method that proves delivery, and make sure the stated consequence is one you will actually carry out, because a deadline that passes quietly teaches the customer that the next one is also decorative.

After that date the remaining options are all real and all have costs attached, and the choice among them is arithmetic rather than principle: a small claims filing for amounts inside the limit, an agency taking a substantial share, or an attorney's demand letter for larger sums. What is worth avoiding is the fourth option, which is doing nothing while continuing to feel aggrieved.

The reason a fixed sequence is better than firmness is that it is impersonal in the most useful sense. Nobody is being singled out, no step requires a decision made while annoyed, and every customer gets the same treatment on the same schedule. Businesses that run one collect faster, argue less, and keep more of their customers, and the whole apparatus is four dates and a template, set up once and used for years.
