Why your invoices keep getting ignored

Usually one of four fixable things: wrong recipient, no PO, a vague description, or no due date.

Before assuming bad faith, check the boring explanations. An invoice sent to the person who hired you rather than accounts. A missing purchase order number, so the system cannot route it. A description too vague to approve. A due date that says "on receipt" and therefore means nothing to a payment run.

Fix those four and the majority of "difficult" clients turn out to have been an admin problem.

The invoice never reached a person who could pay it

The commonest cause is the dullest. You sent it to your contact, your contact is not in finance, and it is sitting in their inbox under two hundred other things. They are not refusing to pay; they have not thought about it since the day it arrived.

Ask at the start who invoices should go to. In any organisation with a finance function, send it there and copy your contact. One question, asked once, removes a fortnight of delay permanently.

It failed a check nobody told you about

Larger customers run automated validation. Missing purchase-order number, a mismatched company name, a bank detail that does not match their supplier record, a tax number absent where their system expects one — any of these can cause a silent rejection. The invoice is not queued, it is out of the system, and the first you hear is when you chase.

Before the first invoice to a new business customer, ask three questions: do you need a PO, what legal entity should I bill, and where do invoices go. The answers take a minute and prevent the most frustrating category of delay, the one where everybody thinks it is progressing.

It is too vague to approve

The person approving is often not the person who hired you and has no idea what "consultancy, September" refers to. They cannot approve what they cannot match to something they recognise, so it waits for a conversation that nobody schedules.

Write lines that a stranger can match to a decision: what was done, when, for whom, against what quote or PO. What to put on an invoice covers the fields; the principle is that the document should be self-explanatory to someone who was not there.

There is no due date on it

"Payment due on receipt" is not a date, and a document with no date on it is not overdue, ever. It sits permanently in a state of being not-yet-late. Write the actual day.

You have trained them

If you chased the last four invoices at day twenty-five, a client learns that day twenty-five is when this becomes real, and behaves accordingly. Terms are enforced by behaviour, not wording. A reminder that arrives the morning after the due date, without fail and without emotion, resets the expectation within about two cycles.

They cannot pay, and nobody wants to say so

Silence often means embarrassment rather than obstruction. Someone who cannot pay this month frequently stops answering rather than admit it, which makes everything worse for both of you. Offering a payment plan explicitly — "would two instalments work?" — gives them a way to say what is going on, and often converts a dead invoice into a slow one.

It arrived too late to feel connected to the work

Goodwill decays fast. An invoice that arrives the day the job finished is part of the job. One that arrives three weeks later is an interruption, and by then your contact has moved on to other things and has to reconstruct why they owe you money. Same-day invoicing is the single cheapest improvement available to most small businesses — how soon after finishing work you should invoice covers why the effect is so large.
