The meaning of open items – definition & explanation

Many entrepreneurs know the feeling: a glance at online banking shows that there is less money in the account than expected. Accounting quickly reveals the reason: some customers have not yet paid their outstanding invoices.

• Open items – invoices from suppliers or customers that have not yet been settled.

In accounting, open items are defined as all invoices that have not yet been paid in full. This can be the case on the expenditure side, when a company still has outstanding payables towards suppliers, as well as on the income side, when customer invoices are still pending. At its core, then, it covers all incoming and outgoing invoices for which the payment process has not yet been completed. You can think of them as a kind of “stopover” in the flow of funds: the money is either already on its way to the recipient or is still expected, but has not yet definitively arrived. Open items therefore act as the interface between classic, backward-looking bookkeeping and forward-looking liquidity planning.

In practice, open items mean that cash flows become traceable and manageable. That is why they matter for small and large companies alike when it comes to securing liquidity.

What is an open items list?

This is an overview in which all items and invoices still outstanding are listed in detail. It helps to ensure that no outstanding receivable is overlooked and that reminders and payment terms are managed precisely.

Important for the meaning of open items: the open items list differs fundamentally from general accounting, because accounting presents all of a company’s figures. Or, to put it more precisely: within accounting, it is a separate statement of entries that have not yet been cleared, and it is kept in more detail than a plain totals and balances overview.

By the way: the difference between accounts receivable open items and accounts payable open items

Debtor open items = on one side there are the items on creditor or supplier accounts. They show unpaid invoices from suppliers or service providers. As soon as the payment is made and posted, the item disappears from the list automatically. How long it stays there depends on the agreed payment terms. That can be a few days, but sometimes months, for example in the case of retentions in construction or project contracts.

Creditor open items = on the other side there are the items on debtor or customer accounts. This is where invoices issued to customers that have not yet been paid are recorded. As soon as the money comes in and the payment is posted in accounting, this item is marked as settled as well.

Open items accounting: example with a table

The following example makes the meaning of open items easier to grasp. It explains all the important fields and terms. A table then illustrates the whole picture.

Open items list: an explanation of all fields and terms

• Invoice/document number: for clear matching and traceability
• Customer data: company/customer name, address, contact person if applicable
• Invoice date: decisive for the deadlines
• Outstanding amount: (net/gross) for the effect on liquidity
• Payment term: due date for managing the timing of reminders
• Status: (open/partly paid/settled)
• Ageing/days overdue: risk assessment & prioritisation
• Dunning level: to keep track of the reminders sent so far
• Further information and notes: for transparency within the team

Example table:

The following example shows how to read and understand the individual fields of an open items list correctly. This also makes clear the meaning of open items and, above all, why they matter in practice.

As you can see here, the list contains not only payments that are already overdue but also outstanding receivables that are still within the payment period. Beyond that, it makes sense to keep two separate lists depending on the type (debtor or creditor).

It also creates clarity, prevents duplicate entries and helps to set priorities. Incidentally, it is even more efficient if you use COMMITLY. All open items are displayed automatically and in real time – including incoming payments, due dates and a view of your liquidity. The true meaning of open items becomes apparent not only when a sudden bottleneck occurs, but also when liquidity is to be managed proactively rather than reactively.

Open items as a decisive lever for your company and its liquidity

Open items create transparency about which payments are still outstanding – both for receivables (debtors) and for payables (creditors). This makes it possible to see at any time when money will come in and when expenses will fall due.

And what does all of this have to do with liquidity? Quite simply: open items let you spot gaps (deviations and funding shortfalls) early and take countermeasures accordingly, for instance when large outflows are due before large inflows.

The meaning of open items with regard to securing & optimising liquidity:

• Prioritising items: the largest and oldest receivables are moved right to the front. Creditors are also planned in a way that allows early payment discounts to be used and bottlenecks to be avoided.
• Managing payment terms: timing and negotiating realistic customer payments and favourable supplier payments.
• Professional dunning: an overview of all levels and deadlines – creating order and faster cash-ins.
• Time categories: buckets measured in days show where risk is rising and where targeted action is needed:
  • 0 – 30 days: still within scope, prepare a reminder
  • 31 – 60 days: slightly overdue, send a friendly reminder and offer to negotiate
  • 61 – 90 days: clearly overdue, further dunning levels up to escalation
  • over 90 days: critical, debt collection & legal steps
• Benefit & urgency: reducing wastage and strengthening your ability to act.

Our tip: before liquidity falls and cash becomes tight, it is better to review open items regularly, assess what they mean for your ability to pay and act accordingly. With COMMITLY you make sure that all this information is processed automatically. Bottlenecks therefore become visible early and you take the right measures in good time.

Tips for implementing open items correctly: how to run your list efficiently

The fact is: an open items list is only as good as the care taken over it. We already know what belongs in such a list and what the individual open items terms mean. Now let us look at how to keep the list reliably and efficiently. Because only those who maintain their open items regularly and in a structured way stay in control and secure their liquidity. Below you will find a few tips for implementation and what they mean in relation to open items:

• Review interval: depending on the size of the list and of the company, review it at least once a week, for example, to keep cash flow and dunning runs active.
• Automatic matching: incoming or outgoing payments are matched automatically to the documents in the system. That saves time and avoids errors.
• Define responsibilities: who follows up receivables regularly and who releases payments?
• Prioritise: deal with the largest and oldest items first.
• Structured dunning: create templates for all levels and define fixed intervals and tone of voice.
• Documentation: if several employees work on one open items list, record all notes, phone calls and dunning levels directly in the overview.

The meaning of open items in practice: common mistakes, their consequences and how to avoid them

At first glance, the open items list looks rather dry. But if it is neglected or kept incorrectly, it can have serious financial consequences. That is why we show you common mistakes, pitfalls and tips on how to avoid them:

• Incorrect master data: payments do not go through or come back. Therefore: maintain and check master data regularly.
• No planned rhythm: reminders are sent too late, incoming payments are delayed. A regular routine helps here, for example a weekly review.
• Poor/manual payment reconciliation: items remain open although they have already been paid, and reports are inaccurate and incomplete. It is better to reconcile with the bank regularly, ideally automatically.
• Early payment discounts are ignored: this drives up costs unnecessarily. In this case a due date calendar and a prioritisation of cash-out are helpful.
• Wrong responsibilities in the team: no employees firmly assigned to monitoring and dunning. A precise allocation of roles is therefore required.
• Frequent rear-view mirror perspective: anyone who only looks at past invoices in their open items often notices bottlenecks too late. It is therefore better to plan for future items falling due as well.

Remember: only those who take the meaning of open items seriously reduce conflicts and protect their cash flow. In the long run, that pays off.

Open items meet planning: how your liquidity becomes predictable

FAQs

• What do open items mean in accounting? Open items are all invoices of a company that have not yet been settled. This includes both outstanding receivables from customers (debtors) and outstanding payables to suppliers (creditors).
• What does clearing an item mean? Clearing means offsetting an outstanding invoice against the corresponding payment. Only once this matching has taken place is the item marked as settled and removed from the open items list. This process is important in order to have an up-to-date overview of receivables and payables at all times.
• What is an open items list needed for? The open items list provides a transparent overview of all unpaid invoices, due dates and dunning levels. It helps you keep an eye on outstanding amounts and actively manage incoming and outgoing payments.
• What do open items mean for liquidity? Open items show at an early stage when money comes in or goes out and where bottlenecks are looming. This makes it possible to identify liquidity gaps, use early payment discounts and set the right priorities for payments.
• What is the difference between debtor and creditor open items? Debtor open items: outstanding receivables from customers who have not yet paid. Creditor open items: outstanding payables to suppliers that still have to be settled. Together, the two lists give the complete picture of a company’s cash flows.

What do open items mean in general accounting? How do they differ? Accounting maps all business transactions, whereas open items represent only the items still outstanding – that is, not yet cleared. This makes them a specific control instrument for payment status.
