AR & Collections terminology

Every term your CFO, AR team, or legal counsel might use when discussing overdue invoices, collection strategy, and cash flow.

D
Days Sales Outstanding (DSO)
The average number of days it takes your business to collect payment after a sale. Lower DSO means faster cash flow. Industry benchmark: under 45 days.
A
Accounts Receivable
Money owed to your business for goods or services already delivered but not yet paid. Appears as a current asset on the balance sheet.
B
Bad Debt
Receivables that are unlikely to be collected and must be written off as a loss. Can be deducted as a business expense when officially recognized.
D
Dunning
The process of systematically contacting customers to collect overdue payments — via email, phone, or letter. Effective dunning sequences recover 60–80% of late invoices.
C
Charge-off
The accounting action of removing an uncollectable debt from the balance sheet as a loss. Charging off a debt does not mean you stop collecting — it's an accounting entry only.
A
Aging Report
A categorized list of all outstanding receivables grouped by how long they have been unpaid (0–30 days, 31–60, 61–90, 90+). Essential for prioritizing collection efforts.
N
Net 30 / 60 / 90
Standard B2B payment terms indicating the number of days a buyer has to pay after the invoice date. Net 30 is the most common; Net 90 increases working capital strain significantly.
C
Contingency Fee
A fee model where the collection agency earns a percentage of what they recover — typically 20–35% for B2B. You pay nothing if nothing is collected. AgentCollect charges 10%.
F
First-Party Collection
When your own company collects its overdue invoices directly, under your brand name. Maintains the customer relationship but requires internal resources and expertise.
T
Third-Party Collection
Outsourcing collection of overdue invoices to a licensed collection agency. The agency contacts debtors on their own behalf. Regulated under the FDCPA (for consumer debt) and state laws.
S
Skip Tracing
The process of locating a debtor who has moved or changed contact information without notice. Uses public records, databases, and AI enrichment tools to find updated addresses and phone numbers.
D
Debt Collection Attorney
A licensed attorney who pursues unpaid debts through legal channels — demand letters, lawsuits, and judgments. Used for large B2B debts ($10K+) when standard collection has failed.
W
Write-off
The accounting act of reducing the value of a receivable to zero when it's deemed uncollectible. Different from a charge-off in timing and treatment.
C
Collection Rate
The percentage of outstanding receivables collected in a given period. Formula: (Total Collected / Total AR) × 100. A key KPI for AR teams.
B
Bad Debt Reserve
An accounting provision estimating the portion of accounts receivable unlikely to be collected. Also called allowance for doubtful accounts.
U
UCC Lien
A legal claim filed under the Uniform Commercial Code that secures a creditor's interest in a debtor's assets. Common in B2B secured transactions.
C
Cease and Desist
A formal request from a debtor to stop all collection communications. In B2B, the rules differ from consumer debt — creditors retain more options.
A
AR Turnover Ratio
Measures how efficiently a company collects receivables. Formula: Net Credit Sales / Average AR. Higher is better. Related to DSO (365 / AR Turnover).
P
Payment Plan
A structured agreement where a debtor pays the owed amount in scheduled installments. Increases recovery rates by reducing the psychological barrier to paying a large sum at once.
D
Demand Letter
A formal notice from a creditor or attorney requesting payment of a debt. Attorney-sent demand letters have 40-60% success rates vs 15-25% for creditor-sent letters.
D
Debtor
A person or business that owes money to another party (the creditor) for goods or services received. In B2B, typically a company with an outstanding invoice.
C
Creditor
A person or business that is owed money by a debtor for goods or services provided. The party initiating collection when payment is overdue.
P
Past Due Invoice
An invoice that has not been paid by its due date. The longer an invoice remains past due, the lower the probability of collection.
C
Collections Workflow
The systematic process of pursuing payment on overdue accounts, from initial reminders through escalation to legal action or write-off.
A
Accounts Payable
Money a company owes TO its vendors and suppliers. The mirror of accounts receivable. Understanding AP helps collectors navigate debtor organizations.
N
Net Recovery Rate
The percentage of placed debt actually recovered after deducting all collection costs and fees. The true measure of collection ROI.
D
Dispute Resolution
The process of resolving disagreements between creditor and debtor about an invoice's validity, amount, or terms. Must be separated from collection to maximize recovery.
