Understanding the Open Invoice: A Beginner's Guide and NetSuite Tutorial

Every successful business must track, organize, and close invoices efficiently to keep cash flowing. Quality financial software helps manage the entire invoicing process with little stress.



What Is an Open Invoice?

An open invoice is a request for payment issued by a seller that has yet to be paid by a buyer. Think of it as an unfinished business transaction in the ledger books. It's an acknowledgment of debt for goods or services still awaiting payment.

“Open invoices are a very common part of the accounting cycle for any growing business that processes credit-based transactions,” financial writer Barbara Cook explains in an article for Tipalti. “Having an ‘open’ or ‘outstanding’ invoice can sound concerning because it’s money you have earned that you have not received. But the reality is that it’s proof of your transaction and can provide flexibility for both parties, which can make for smoother business transactions.”

The invoicing process begins when a company sells a product or service. At that time, the seller sends an invoice to the buyer detailing:

• Amount owed
• Description of the goods or services
• Payment terms
• Due date

This invoice remains "open" until the buyer completes the payment.

According to Versapay’s Annual State of Digitation in B2B Finance report, surveyed AR teams process nearly 2,500 invoices per month on average, excluding outliers. Additionally, 77% say they are behind on invoice processing.

Software, like a NetSuite ERP system, automates invoice processing so businesses can handle these large volumes more efficiently. It reduces manual entry, speeds up processing time, and decreases the risk of error.

Handling Issues With Open Invoices

An open invoice is like a log in a river. Too many will halt your cash flow. That’s why we suggest incorporating these tips into your operations to help close pending invoices as quickly as possible:

1. Communicate Promptly: Address discrepancies or delays in payment by keeping an open line of communication with the other party.
2. Maintain Clear Records: Keep detailed records of all transactions and communications to resolve disputes more effectively.
3. Create Flexible Solutions: Be open to negotiating payment plans or resolving disputes to maintain good business relations.
4. Use Technology: Implement automated accounting software to track invoices, send reminders, and manage payments efficiently.

Automation is a particularly formidable tool for creating efficient and effective invoice processes. In fact, a B2B payments study says automated accounts receivable processes can cut day sales outstanding by 23 days on average for companies handling more than 20,000 invoices per month. 

Software such as NetSuite’s invoice processing automatically generates and sends invoices and manages collections while offering payment options such as cash, check, credit card processing, and EFT. This tool reduces the paperwork your accounting team must handle and increases financial data accuracy.

It also saves a significant amount of time and money. The CPA Journal reports that automated invoicing can cost 40% to 90% less than manual processes.

NetSuite’s key invoice processing features include:

• AR Aging – NetSuite’s AR Aging report lists overdue invoices and categorizes them by due date. The system allows you to set your own terms for what constitutes “overdue,” and you can offer discounts for early payments.
• Automatic Sending – You can program the system to send invoices as they’re generated. If you’re billing hourly, NetSuite can invoice when your employees enter hours and/or expenses. Additionally, you can use NetSuite to process these documents in batches overnight.
• Automatic Deposits – You can establish rules in NetSuite that govern how it records payments. It can automatically apply customer payments to corresponding invoices and immediately enter the general ledger account or collect in a designated account to be deposited later as a lump sum.
• Automatic Dunning – If invoices stay open, eventually, they will become “outstanding.” NetSuite’s automated dunning letter procedure manages delinquent accounts so you can maintain cash flow.

This list only covers the basics of NetSuite’s financial automation capabilities. Explore the system’s features further during your free consultation with SuiteDynamics.
