What is the Cash Application Process?
The cash application process is the accounts receivable (AR) workflow of matching incoming customer payments to their corresponding open invoices and posting those payments to the correct customer accounts in an ERP or accounting system. It happens after a payment lands, and it’s the step that actually closes out a receivable. That’s what restores the customer’s available credit and gives finance an accurate, real-time read on cash position.
It sits right at the tail end of the order-to-cash cycle, one of the final stages of the broader accounts receivable process. A payment shows up by check, ACH, wire, credit card, or lockbox, usually with remittance advice attached that says which invoices the payment covers. The AR team captures that remittance data, links each payment to one or more open invoices, works through any exceptions, and posts the result. Get it right and days sales outstanding (DSO) stays low while the cash forecast stays trustworthy. Atradius data shows around 43% of credit-based B2B sales in the US are currently overdue, which means the volume of payments needing accurate application - including partial pays, deductions, and short-pays - is higher than most AR teams plan for.
Since it touches the ledger, cash application usually runs on documented procedures. Teams that write it down in their accounts receivable SOP and broader accounting playbook tend to see more consistent matching, fewer disputes, and cleaner audit trails.
Key Characteristics of Cash Application
- Post-payment: It only kicks off after funds arrive, which is what sets it apart from collections, which happens before payment.
- Match-driven: It lives or dies on tying payments to invoices accurately, using invoice numbers, PO references, and amounts.
- Exception-heavy: Partial payments, deductions, short-pays, and missing remittance all need investigation and a bit of judgment.
- ERP-integrated: The last step is posting validated matches to the customer account so the invoice clears.
Cash Application Examples
Example 1: Lockbox check with remittance stub
Picture Maria, an AR clerk at a regional distributor. One of her long-time customers still mails paper checks, and this one shows up with a printed stub listing three invoice numbers. Maria pulls the morning lockbox file, sees the check total lines up cleanly with those three open invoices, and posts the payment. All three clear in the ERP, the customer’s credit frees up, and she’s on to the next one. This is cash application working exactly the way it’s supposed to, which, let’s be honest, isn’t every payment.
Example 2: ACH payment with no remittance
Now picture the other kind of day. A manufacturer’s bank shows an ACH deposit landed overnight, but there’s no remittance advice anywhere, and the amount doesn’t match any single open invoice. You can’t just guess and post it. So it sits there as unapplied cash, quietly understating reported AR, while someone on the team emails the customer asking what it was actually for. Until they reply, the books don’t fully reflect the money that’s already in the account.
Cash Application vs Cash Collection
People mix these two AR functions up all the time, but they sit at opposite ends of the payment timeline. Cash collection is the chasing part, getting customers to pay. Cash application is matching and posting money that already arrived.
| Aspect | Cash Application | Cash Collection |
|---|---|---|
| Timing | After payment is received | Before payment is received |
| Purpose | Match and post payments to invoices | Get customers to pay outstanding invoices |
| Typical activity | Remittance matching, exception handling | Reminders, dunning, dispute follow-up |
How Glitter AI Helps with Cash Application
Here’s the uncomfortable truth about cash application: it’s high-volume, full of judgment calls, and far too often it really only lives in the head of the one analyst who has been doing it for years. That’s fine until they’re on vacation or they leave. With Glitter AI, that analyst just records themselves doing the actual matching and posting once, and you get a clear, step-by-step guide in minutes. The next AR hire learns remittance matching and how to clear unapplied cash the same way every time, instead of reverse-engineering it from a messy ERP.
Keep that walkthrough right alongside your accounts receivable SOP and your standard procedure for paying vendors. Anchored to a finance-wide guide for documenting accounting procedures, a few good things happen at once: you make fewer posting errors, you onboard people faster, and when you eventually roll out automation it goes more smoothly, because the rules are already written down before anyone has to encode them.
Teach your co-workers or customers how to get stuff done – in seconds.
Frequently Asked Questions
What is the cash application process in accounts receivable?
It is the AR process of matching incoming customer payments to their open invoices and posting them to the correct accounts, which clears the receivable and updates cash position.
What are the steps in the cash application process?
Receive the payment and remittance, capture the remittance data, match the payment to open invoices, handle exceptions, post to the ERP, and reconcile against bank deposits.
What is unapplied cash and how do you reduce it?
Unapplied cash is money received that has not yet been matched to an invoice, often due to missing remittance or partial payments. Standardized matching rules and automation reduce it.
What is the difference between cash application and cash collection?
Collection is pursuing customers to pay before money arrives; cash application is matching and posting payments that have already been received.
What is the difference between cash application and bank reconciliation?
Cash application allocates payments to specific open invoices in the AR ledger, while bank reconciliation verifies internal cash records against the bank statement.
Why is remittance matching difficult?
Remittance advice often arrives separately from the funds and in many formats, such as emails, PDFs, EDI files, and paper stubs, making it hard to aggregate and match accurately.
How do you handle partial payments and deductions?
Split the payment against the invoice, track the remaining open balance, and code deductions or short-pays to the correct dispute or allowance reason for follow-up.
How does cash application automation work?
Rule-based matching plus OCR and machine learning extract remittance data and predict invoice matches, often reaching 90% or higher straight-through processing rates.
How does cash application affect DSO?
Faster, more accurate application clears receivables sooner and reduces unapplied cash, which lowers days sales outstanding and improves working capital visibility.
Who is responsible for cash application?
It is typically owned by the accounts receivable or cash application team within finance, often guided by a documented accounts receivable SOP.
