Outstanding Invoice

Outstanding Invoice

An outstanding invoice is a bill sent but unpaid, showing due payment for delivered goods or services—vital for cash flow and accounts receivable tracking.

An outstanding invoice refers to a bill that has been issued to a customer but has not yet been paid. It represents a pending payment for goods or services already delivered and is a key component of managing accounts receivable in any business. 

Monitoring outstanding invoices maintains healthy cash flow, identifies late payments, and ensures timely follow-ups.

What Is an Outstanding Invoice

An outstanding invoice is a bill that a customer or client has received from a business for goods or services delivered but has not yet paid. It represents an account receivable on the company’s balance sheet and indicates that payment is still due within the agreed-upon terms, such as net 30 or net 60 days

Outstanding invoices can affect a business’s cash flow, as they tie up revenue that the company has earned but not yet collected. While some outstanding invoices are simply pending payment within the normal timeframe, others may become overdue if the customer fails to pay by the due date. 

Managing outstanding invoices effectively maintains healthy financial operations, ensuring timely follow-ups, and reducing the risk of bad debts. Businesses often use accounting software or invoice automation software to monitor these balances, send reminders, and, if necessary, escalate to collections or legal action.

Outstanding Invoices vs Overdue Invoices

Both outstanding invoices and overdue invoices refer to unpaid bills, but they are not the same. Knowing how they differ can help you track payments more accurately and improve cash flow management. 

Here's a quick comparison to clarify the distinction:

Term

Example
Outstanding Invoices
All unpaid invoices, whether or not the due date has passed
- Not yet due
- Overdue invoices
Invoice due May 15 (today is May 1) → Outstanding
Overdue Invoices
Unpaid invoices past their due date
- Only invoices past the due date
Invoice due April 15 (today is May 1) → Overdue

How to Collect Outstanding Invoices

Collecting outstanding invoices requires a structured and professional approach to maintain good client relationships while ensuring timely payments. Here's a step-by-step guide to help you collect them effectively:

Review Invoice Details

Before taking any action, make sure the invoice was sent to the right contact and that all details—such as the amount, due date, and services rendered—are correct. It's important to confirm there are no disputes or misunderstandings that might be holding up payment.

Send a Friendly Reminder (1–7 Days Overdue)

If the invoice is just a few days past due, start with a polite reminder. A short email or message works well. Reattach the original invoice and gently ask if they’ve had a chance to process the payment, offering assistance in case they need help or clarification.

Follow Up with a Firmer Message (8–14 Days Overdue)

When the payment is a week or two overdue, send a follow-up message that’s a bit more direct. Keep the tone professional and express the urgency of the matter. Let the client know you’re still open to helping resolve any issues that might be delaying payment.

Make a Phone Call (15–30 Days Overdue)

A personal phone call can be more effective than emails at this stage. It allows you to address any concerns in real time and find out why the payment hasn’t been made. A calm and respectful conversation can often lead to quicker resolutions.

Send a Final Demand Letter (30+ Days Overdue)

If the invoice remains unpaid, a formal final demand letter signals that you're taking the matter seriously. Clearly state the amount owed, the original due date, and the steps you’ll take if the payment is not received by a certain deadline, such as halting services or initiating collections.

Consider Charging Late Fees

If your payment terms included late fees, this is the time to apply them. Mentioning late fees can motivate some clients to settle their balances more quickly, especially if they see the total amount increasing.

Offer a Payment Plan

Some clients may be unable to pay the full amount right away. Offering a structured payment plan can help you recover the funds over time while showing flexibility and goodwill, which can help preserve the business relationship.

Suspend Services

When payment delays extend too far, it’s reasonable to pause any ongoing work or support. Let the client know this is a temporary measure until the account is brought up to date, and be clear about what will be affected.

Use a Debt Collection Agency (60–90+ Days Overdue)

If multiple attempts to collect have failed, you may need to involve a debt collection agency. These agencies specialize in recovering overdue payments, though they typically take a percentage of the amount collected.

Take Legal Action

As a last resort, especially for large or critical invoices, consider legal action. You may file a claim in small claims court or consult with an attorney for advice. Be prepared with documentation showing all attempts to resolve the matter amicably.
