When a collection call goes wrong, the first assumption is usually that it is a customer problem: a slow payer, a difficult account, someone avoiding the phone. But sometimes the problem starts earlier, before anyone picks up the phone at all.
In our work with larger organizations, we frequently find that the A/R aging itself is inaccurate. Not because of anything the customer did, but because of how information was entered (or not entered) by the finance team.
This is not about blame. Many people working in finance department roles, particularly in data entry and transaction processing, were hired to enter information accurately, not to fully understand how that information flows through to the balance sheet and income statement. When that context is missing, and when clear processes are not in place, predictable errors follow.
If you have noticed that your overdue invoices seem to keep growing regardless of how many past due statements your team sends, the aging itself could part of the problem. We wrote about the process side of this in The Real Reason Your Company Has Too Many Overdue Invoices. Here, we are going deeper into specific finance department scenarios that impact the aging before collections begins.
Here are the four we see most often, what they cost you, and how to fix them.
1. Pre-Billing: The Invoice That Should Not Exist Yet
Pre-billing is invoicing a customer before goods have shipped or services have been delivered.
A common scenario:. A bookkeeper is instructed to create and mail an invoice for work that is close to finished. And now there is a balance on the books, sometimes a significant one, for a product that has not left the warehouse or work that has not been completed.
We have seen this with invoices as large as $200,000 sitting on an aging report for orders that were not even close to being fulfilled.
Pre-billing overstates both accounts receivable and revenue on your financial statements. It also creates a collections problem with no solution: you cannot collect on an invoice for something the customer has not received. And if someone tries, that conversation will not go well.
▶ The Fix Invoice creation should require a documented fulfillment trigger, typically shipping confirmation or delivery documentation. An instruction from sales alone should not be enough. If there is no supporting documentation to show that goods or services have been delivered there should be no invoice period. |
2. Deposits That Do Not Get Applied: A Confusion Factory
When a customer makes a deposit on a larger order, that payment should post as a credit on the customer account. When the final invoice is created, the credit nets against it automatically, and what remains is the true balance owed.
What often happens instead: the deposit is received and recorded somewhere, but not correctly tied to the customer account. The final invoice goes out for the full amount. The customer, who knows they already paid a portion, receives what looks like a billing error, so they ignore it. When a collection callis made on the full balance, the customer will bring up the deposit, which reflects poorly on your organization.
Beyond the optics, an improperly posted deposit may misrepresent your liabilities. A customer deposit is money owed back if the order does not complete. It is a liability until the work is done and needs to be accounted for accurately.
▶ The Fix Every deposit should be posted as a credit balance on the A/R aging, clearly linked to the customer account. When the invoice is created, the credit applies automatically and the remaining balance reflects what is actually owed. If deposits arrive without clear instructions on how to apply them, build a hold: billing waits until accounting receives written guidance. No customer who has paid in advance should receive a collection call on the full balance. |
3. Unapplied Credits: Clutter That Costs You
Credits accumulate for legitimate reasons: returns, pricing adjustments, billing corrections. That is expected. What is not expected is what often happens next: nothing.
Without a defined process for applying a credit to an open invoice or issuing a refund, credits sit in the aging indefinitely. They clutter the report. They make it harder to see what is actually owed. And they create friction in collections: a customer who knows they have a credit on file will not respond well to a collection call on invoices that credit should offset. They will point it out themselves, and they will not be impressed that you did not already know.
Unapplied credits are also a liability. That money may be owed back to the customer. Leaving it unresolved indefinitely is not just a collections problem — it is an accounting one. Sending statements that show unapplied credits signals disorganization. Making a collection call when a credit balance exists signals something worse: that no one is watching the account.
▶ The Fix Establish a clear policy: how credits are applied, who is responsible, and within what timeframe. Credits without a corresponding open invoice that age past 30 days should automatically trigger either an application or a refund decision. Add unapplied credits to your A/R KPI dashboard and review them weekly. This is a solvable problem — it just requires a process and an owner. |
4. Unapplied Cash: Money In, But Going Nowhere
Unapplied cash is a payment received but not matched to an invoice. It happens for a variety of reasons: the remittance advice was missing, the payment amount did not match exactly, or no one followed up with the customer to clarify what the payment was for. The result is a payment sitting in a holding account while the corresponding invoice continues to age.
This problem scales quietly. Without a process for tracking and resolving unmatched payments, the balance grows. We have worked through situations with clients carrying $600,000 or more in unapplied cash. That is a figure that materially misrepresents both the accounts receivable balance and potentially the cash position on the financials.
The collections impact is direct: if a customer payment is sitting unmatched and someone calls that customer about the open invoice, the customer knows they paid. You do not. That erodes the credibility that productive collection conversations depend on, and again, reflects poorly on your organization.
▶ The Fix Every unmatched payment should trigger an immediate step: contact the customer, request remittance advice, and get it matched. This needs to be a tracked process with an assigned owner and a resolution deadline. Unapplied cash older than 15 days should be flagged as an exception, not accepted as normal. Track it as a KPI. If there is a material balance today, start working through it now. |
Process Is the Fix. Oversight Makes It Stick.
These four errors, pre-billing, unposted deposits, unapplied credits, and unapplied cash, do not usually appear in isolation. When we see one, we often find the others. That pattern is a signal: the finance department is running without the processes and training it needs to produce an accurate aging.
The response is not to replace the team. It is to build around them. Every transaction type should have a documented process. Every person handling that transaction should be trained on what it means, not just how to enter it. And someone needs to own oversight: watching for anomalies, monitoring KPIs, and catching problems before they compound into six-figure issues.
No one should be making a collection call on a balance that is not yet due, has already been paid, or is offset by a credit the customer knows about. It wastes time on both sides and signals that your organization does not have a handle on its own numbers. A clean aging is the foundation.

If any of this sounds familiar, a 30-day engagement is the place to start. We come in, work through the past-due backlog, identify what is causing the problem, and help train and transition your team so they are equipped to manage it going forward. You get the immediate cash-flow impact and a finance department that is in a stronger position than when we arrived.
