An accounting glossary defines the words a finance team uses to record, reconcile, report, and plan. This one defines 721 finance and accounting terms in 20 areas, from accounts payable and receivable to the month-end close, reconciliation, FP&A, controls, and AI in finance.
Most finance glossaries cover one function, so you end up checking four or five sites to cover AP, AR, the close, and planning. This glossary puts them in one place. Each term’s definition sits on this page. The 44 terms with a full guide of ours link to it. The rest are getting their own dated pages with a worked example, the journal entry where one applies, and the terms they get confused with.
To use it, search any term or abbreviation, such as GRNI, DSO, DPO, or ASC 842, jump A to Z, or filter by one of the 20 areas. If you’re new to a role, start with the role paths for a new controller, staff accountant, or AP and AR clerk. Every area and role list prints on its own, with no sign-up.
A glossary isn’t the same as a chart of accounts. Your chart of accounts is the numbered list of ledger accounts you post to, such as 1000 for cash, 2000 for accounts payable, and 4000 for revenue. A glossary defines the words your team uses about those accounts and the work around them, so everyone, including your auditors, reads a term like cutoff or accrual the same way.
Nearly every other term on this page builds on them.
The language of the close and of control first, then the standards and the numbers leadership asks for.
The terms you use on day one: entries, ledgers, reconciliations and the review that follows.
Invoices, matching, payments and cash application, from purchase order to aging report.

In detail
Accounts payable terms describe the invoice-to-payment cycle, from the purchase order and goods receipt through three-way match, approval, and the payment run to the AP accrual at month-end. The full list holds 83 AP and procure-to-pay terms; these are the groups to learn first.
GRNI (goods received not invoiced) trips up new AP teams: it’s a liability for goods you’ve received but haven’t been billed for yet, so it belongs with AP accruals, not with receivables.
Accounts receivable terms describe how you bill customers, extend credit, collect, and apply cash, from the invoice and credit limit through dunning and cash application to AR aging, the allowance for credit losses, and DSO. The full list holds 76 AR, billing, and collections terms.
Under US GAAP, ASC 326 (the current expected credit loss model, or CECL) calls the reserve the allowance for credit losses, though many teams still say allowance for doubtful accounts. Either way, the AR subledger should tie to the general ledger at month-end, and that tie-out is one of the first things an auditor asks to see.
Month-end close terms describe how your team records, adjusts, reconciles, reviews, and locks a period so the financial statements are complete before anyone reports them. They span three areas in the full list: the close itself (30 terms), journal entries and accruals (39), and reconciliation (25).
Record-to-report (R2R) is the wider process, from posting a transaction to publishing the statements, and the month-end close is the part of it that runs on a deadline each month. Group the close terms by the stage where your team meets them:
| Close stage | What happens | Terms you’ll use |
|---|---|---|
| Pre-close | Set dates, owners, and the cutoff | Close calendar, close checklist, accounting period, accounting cutoff, pre-close validation |
| Entries | Record what the ledger is missing | Accruals, prepaid expenses, deferred revenue, reclassification entry, recurring journal entries, reversing entries, manual journal entry |
| Reconciliations | Tie each balance to an outside record | Bank reconciliation, subledger reconciliation, intercompany reconciliation, reconciling items, suspense account, roll-forward schedule |
| Review | Explain changes and approve the work | Flux analysis, close variance threshold, materiality, journal entry approval, preparer and reviewer, workpaper |
| Reporting and lock | Produce the statements and lock the period | Adjusted trial balance, financial consolidation, intercompany eliminations, close package, period lock, post-closing trial balance |
Soft close vs hard close is the pair most teams define loosely. A soft close produces internal numbers with fewer adjustments, while a hard close completes every step and locks the period to new postings. A locked period can still be reopened by an authorized user with approval and a documented reason. For the steps in order, see the month-end close process guide.
FP&A terms cover how your finance team plans, forecasts, and explains results: budgets, rolling forecasts, driver-based plans, budget vs actual, variances, and the SaaS metrics leadership reads. The full list holds 87 FP&A terms, plus financial ratios (26) and subscription metrics (29).
FP&A works from actuals, and actuals come from the close. A missed accrual at month-end shows up as a false variance in the budget vs actual review. That’s why a finance manager needs the close terms as much as the planning ones.
AI in finance terms describe what software can now do in the close, AP, AR, and FP&A, and who stays accountable for the result. The full list holds 30 terms, from agentic AI and large language models to guardrails, audit trails, and model drift.
The terms that matter most to a CFO are the ones that decide control: what an agent may prepare, what needs a named approver before it posts, how every action is logged, and how a wrong answer gets caught. Ask these questions before an AI tool touches your ledger:
| Term | Where it shows up in finance | Control question a CFO should ask |
|---|---|---|
| AI agent | An agent reconciles a bank account, drafts the entry for a missing fee, and routes it for review | What can it do on its own, and what needs a named approver before it posts? |
| Human in the loop | A reviewer approves each proposed journal entry before it reaches the ERP | Which outputs need a person’s sign-off, and is that person separate from whoever set up the agent? |
| AI guardrails | Rules stop an agent from posting above a threshold or into a locked period | What is the agent blocked from doing, and who can change those limits? |
| AI audit trail and explainability | A log shows what the agent read, what it proposed, and why | Can an auditor trace every entry back to its source data and reasoning? |
| LLM hallucination | A model states a balance or a policy that isn’t in your data | How is every number tied to a source record before anyone relies on it? |
| Retrieval-augmented generation (RAG) | The model answers from your ledger, contracts, and policies instead of from memory | Which sources does it read, and how current are they? |
| AI confidence score | A low-confidence match goes to a person instead of clearing on its own | What score sends work to review, and who set it? |
| Prompt injection | Text hidden in a vendor invoice tries to tell the agent to change bank details | Can content inside a document ever change payment details or approvals? |
Continuous close and zero-day close sit with the close terms, because they describe how the close runs, not the software behind it.
A new controller needs the language of the close and of control first: cutoff, accruals, reconciliations, flux analysis, materiality, journal entry controls, segregation of duties, and SOX. Then come the standards and the metrics leadership asks about.
Auditors listen for precise control language, so these are the terms your team should use exactly:
The core terms are the same in every industry, and the extras change with the business. Each industry close guide lists the extra terms and the entries behind them:
| Industry | Extra terms a controller meets | Guide |
|---|---|---|
| SaaS | ARR, deferred revenue, ASC 606, costs to obtain a contract (ASC 340-40) | SaaS month-end close |
| Healthcare | Payer contractual allowances, patient AR, cost report settlements | Healthcare month-end close |
| Retail and ecommerce | Inventory write-downs, returns reserve, payment processor clearing | Retail and ecommerce month-end close |
| Logistics and distribution | Freight accruals, landed cost, inventory in transit | Logistics and distribution month-end close |
| Energy, oil, and gas | Joint interest billing, revenue distribution, depletion | Energy, oil, and gas month-end close |
A new staff accountant needs about 30 terms on day one, and an AP or AR clerk needs about 25. Start with the list for your role below; each one prints on its own.
Use the print view to turn any of these lists into a cheat sheet for a new hire, a training manual, or an audit memo. Each printed term keeps its definition and its page address, so the sheet still points to the worked examples. To see where each term shows up in the actual work, pair the staff accountant list with the month-end close checklist template.
If you keep the books for a small business, print the Accounting foundations list instead. It covers the basics, from assets and liabilities to the trial balance and bank reconciliation, and the small business month-end close guide maps them to the tasks you do each month.
Your finance team should agree one written definition for the terms behind board numbers and close decisions: revenue, ARR, bookings, billings, deferred revenue, gross margin, NRR, CAC payback, days to close, and materiality.
These terms break down in practice because sales, FP&A, and accounting each count a different event. Write each definition down with its owner and the system field it comes from. On NetSuite, that means naming the saved search or field behind each number. For the NetSuite close itself, see the NetSuite month-end close guide.
Example
A customer signs a one-year, $120,000 subscription on January 1, billed upfront on Net 30 terms. The single contract creates four different events.
| Event | Date | Amount | Journal entry | What it changes |
|---|---|---|---|---|
| Booking | January 1, contract signed | $120,000 | None | Bookings and ARR rise by $120,000 |
| Invoice (billing) | January 1 | $120,000 | Debit AR $120,000; credit deferred revenue $120,000 | Billings rise by $120,000; revenue is still $0 |
| Cash | January 31, paid on Net 30 | $120,000 | Debit cash $120,000; credit AR $120,000 | Cash rises by $120,000; revenue is still $0 |
| Revenue | Each month-end, January through December | $10,000 a month | Debit deferred revenue $10,000; credit revenue $10,000 | Revenue rises $10,000 a month as deferred revenue falls |
At March 31, the company has booked, billed, and collected $120,000, but it has recognized only $30,000 of revenue, with $90,000 left in deferred revenue. If sales reports bookings, FP&A reports ARR, and accounting reports revenue without shared definitions, three people give the board three different numbers for one contract.
The terms people confuse most are pairs that sound alike but differ in timing, in which ledger or report they sit in, or in what a metric counts. The full list holds 33 of these pairs, each with a one-line difference.
| Kind of confusion | Pairs in the list | Quick test |
|---|---|---|
| Timing | Accrual vs deferral, deferred revenue vs accrued revenue, prepaid expenses vs accrued expenses, reversing vs adjusting entries, accrual vs cash accounting | Has the cash moved, and has the revenue or expense been earned or incurred? |
| Ledger and report | General ledger vs subledger, general ledger vs trial balance, trial balance vs balance sheet, adjusted vs unadjusted trial balance | Is it a record of transactions, a list of balances, or a statement? |
| Documents and process | Invoice vs purchase order, invoice vs receipt, two-way vs three-way match, credit memo vs refund, reconciliation vs review | Which document comes first, and does money move? |
| Metrics | ARR vs MRR, bookings vs revenue, EBITDA vs operating income, gross margin vs markup, DSO vs DPO, cash flow vs profit, revenue vs income | What exactly does the number count, and over what period? |
| Roles and systems | Controller vs CFO, FP&A vs accounting, close management vs ERP | Who owns the work, and where does it live? |
Some pairs mean the same thing. Deferred revenue and unearned revenue name one liability, so pick one term and use it everywhere in your reporting.
We built Empty Spaces as an AI finance platform, and our Close Agent works the close checklist this glossary describes: it reconciles accounts, investigates exceptions, and prepares entries and workpapers. Nothing posts to your ERP until a named approver signs off, and every entry keeps who prepared it, who approved it, and why. See how our Close Agent works.
Tell us where the work gets stuck. We’ll walk through how the agents could help.
