Accrual Accounting

Your board asked to see December revenue. The cash didn't arrive until January 8th, but finance said it still counts for December, and sales asked why. The answer is accrual accounting, and it changes how every financial metric in your business is calculated. Accrual accounting records revenue when it is earned and expenses when they are incurred, regardless of when cash actually changes hands. Under GAAP, accrual accounting is required for any company that carries inventory or has annual revenue above $26 million (under IRS rules), and it is effectively required for any company taking on institutional investors or preparing audited financials. The principle is that financial statements should reflect economic activity in the period it happened, not the period the bank balance moved. A subscription billed in December and paid in January belongs in December. A software license fee covering six months starting in November belongs in both November and April, ratably. Once you move from cash-basis to accrual, your P&L, balance sheet, and cash flow statement tell three related but different stories, and understanding how they differ becomes a permanent part of running the business.

How it works

The matching principle is the core of accrual accounting: revenue is recognized in the same period as the expenses incurred to generate it. That sounds simple, but it produces layers of timing adjustments that finance teams work through at every period-end. On the revenue side, services performed in December but billed in January appear as accrued revenue (an asset) in December, then convert to cash when collected. On the expense side, software subscriptions paid annually in January are spread across 12 months as prepaid expenses that amortize each month. Bonuses earned in Q4 but paid in Q1 are accrued as a liability in Q4. Each of these adjustments needs a journal entry at period-end and a reversing entry when the cash transaction posts. So your P&L in any month is a mix of actual cash transactions and estimated accruals, and it is only as accurate as those accrual estimates are complete and correct. Managers who judge performance from the bank balance alone miss everything the accrual system is tracking.

Accruals that accumulate, reversals that get missed

Accrual accounting means managing the full lifecycle of every accrual: create it in the period it's earned or incurred, reverse it when the actual transaction posts, and investigate when the actual differs from the estimate. When teams skip the reversal step, accruals pile up. A bonus accrual posted in December that was never reversed when the bonus was paid in March means the expense is recognized twice, once as the accrual and once as the cash payment. That overstates expenses and understates income in Q1. Inconsistent accrual practices also wreck period-over-period comparability. If December accruals are aggressive (catching every estimated expense) and March accruals are minimal (only what's been invoiced), December looks expensive and March looks cheap, even if the underlying activity was identical. Auditors are trained to look for this pattern because it is one of the ways earnings get managed. Internal controls around accruals should include documented cutoff policies (what must be accrued and what can wait for the actual invoice), a review of prior-period accruals before current-period accruals are posted, and a monthly comparison of accrual-to-actual variances by category.

How accounting systems enforce accrual discipline

The gap between accrual accounting in theory and in practice is mostly a systems and workflow problem. Systems that automate recurring accruals (depreciation schedules, prepaid amortization, subscription revenue recognition) cut the number of manual judgment calls at period-end. Systems that require documented support for manual accrual journal entries create an audit trail that makes the accrual lifecycle reviewable. Systems that let users post to prior periods without approval, or book cash transactions without triggering the matching accrual reversal, set up the inconsistency problems described above. When you evaluate accounting software, test these points specifically. Does the system generate reversing journal entries for accruals automatically, and does it do so at period open or only when someone triggers it? Can users bypass accrual logic, for example by recording a vendor payment without clearing the related accounts payable balance? What does the system do when an actual invoice differs materially from the accrual estimate: does it flag the variance or quietly post the difference?

Questions to ask

• How does the system handle automatic accrual reversals? Are they generated at period-end or created manually, and what happens if a reversal is missed?
• Does the system support standing or recurring accrual journal entries for predictable items like depreciation, rent, and prepaid amortization?
• What controls exist to prevent users from posting cash transactions without clearing the corresponding accruals (AP, AR, prepaid)?
• How does the system handle accrual-to-actual variances? Is there a variance report, and does it flag items above a defined threshold?
• Can the system enforce cutoff dates, so transactions dated in the current period can't be posted to the prior period without explicit approval?

Common mistakes

The first mistake is accruing inconsistently from month to month. If the accrual process depends on one person's judgment about what to include, completeness will vary with that person's workload, their awareness of pending invoices, and how they read the cutoff. The result is a P&L that doesn't reflect the real cost of running the business in any given month. The fix is a documented accrual policy that specifies categories, amounts, and timing, instead of judgment calls made under close pressure. The second mistake is not reversing accruals when actuals post. This is a systems problem as often as a human one. Where the accrual and the actual post to different subsystems (accrual in the GL, actual in AP), the reversal may not trigger automatically. The most common case is a year-end bonus accrual that isn't reversed when payroll runs in Q1, which hits compensation expense twice, overstates Q1 costs, and muddies variance analysis.

Accrual basis against cash basis

Cash basis records a transaction when money moves. Accrual basis records it when the obligation arises, which is what the matching principle requires and what US GAAP financial statements are prepared on. The practical difference shows up in two places: a December invoice paid in January, and prepaid annual contracts. Cash basis puts both in the wrong period, which is why lenders and auditors ask for accrual statements.

Comparing accounting software

The dividing line in this category is whether a tool owns the ledger or sits beside it running reconciliations and the close checklist. Once accrual accounting is settled as a requirement, read the Accounting Software category guide for how the market splits, then weigh the BlackLine profile against the FloQast profile on that requirement rather than on the feature list. Our BlackLine pricing breakdown records what the vendor publishes and what is quote-based. The BlackLine against FloQast comparison sets two of them side by side on the same criteria. Before you book demos, put your own numbers through the accounting software ROI calculator so the business case is written down before a vendor writes it for you.
