An invoice reaching 30 days overdue is common, and on its own does not mean anything has gone wrong. What matters is what you do in the days that follow. Here is a simple, professional approach that protects both your cash flow and the customer relationship.
Step 1: Check your own records first
Before contacting the customer, confirm the invoice was sent to the right person, at the right address or email, and that there is no dispute already logged about the goods or service provided. A quick internal check avoids an awkward conversation about something that turns out to be your own error.
Step 2: Send a friendly, factual reminder
The first contact at 30 days should be brief and non confrontational. State the invoice number, amount and due date, and ask if there is anything outstanding on their end, such as a missing document or query, that is holding up payment. Most overdue invoices at this stage are simple oversights.
Step 3: Pick up the phone
If there is no response to a written reminder within a few days, a phone call is far more effective than a second email. It is harder to ignore, and gives the customer a chance to explain their situation, which might reveal a genuine cash flow issue worth planning around together.
Step 4: Get a commitment in writing
Once you have spoken to the customer, follow up with a short email confirming what was agreed, whether that is payment by a specific date, or a payment plan for a larger balance. Having this in writing protects you if the conversation is later forgotten or disputed.
Step 5: Escalate calmly if the date is missed
If an agreed date passes without payment, a firmer follow up is appropriate, referencing the previous commitment directly. This is also the point where many business owners start to feel uncomfortable chasing further, which is exactly where a dedicated credit control process, whether managed internally or outsourced, protects both your cash flow and your energy.
When to bring in support
If an invoice moves past 60 or 90 days with no clear resolution, it is worth involving a dedicated credit control professional. Not because the situation is necessarily hostile, but because a consistent, structured follow up process recovers more money, more often, than ad hoc chasing squeezed in around the rest of your work.
