Journal Entry Cheat Sheet: Debits and Credits for Common SaaS Transactions

Who it's for: anyone posting or reviewing journals in a SaaS or tech finance team, especially if you're new to SaaS or need a quick double-check.

What you'll get: the debits and credits for the 20 most common SaaS transactions, from annual billing to share options, all in one place with MonthEndClub Co Ltd numbers, plus AI prompts for checking journals.

Reading time: about 10 minutes end to end, or 30 seconds to find the one you need.

Why a cheat sheet helps

Most month-end journals are the same twenty or so entries, repeated. Getting them right every time is less about genius and more about having the pattern in front of you. This page is that pattern: what to debit, what to credit and the one thing that usually goes wrong.

All examples use MonthEndClub Co Ltd, a fictional UK SaaS company, with UK VAT at the standard rate of 20% where VAT applies. Every journal balances; check yours does too.

Key terms

  • Debit (Dr) and credit (Cr): the two sides of every entry. Debits increase assets and expenses; credits increase liabilities, equity and income.
  • Deferred revenue: billed but not yet earned. A liability.
  • Accrued income: earned but not yet billed. An asset.
  • Accrual: a cost incurred but not yet invoiced. A liability.
  • Prepayment: a cost paid for a future period. An asset.
  • Clearing account: a temporary account that holds amounts until they're matched, such as a payment processor balance.

A quick memory aid: DEAD CLIC. Debits increase Expenses, Assets and Drawings; Credits increase Liabilities, Income and Capital.

Revenue and billing

1. Annual subscription invoiced upfront

Invoice £24,000 + VAT for 12 months' service.

Account Dr Cr
Trade debtors £28,800
Deferred revenue £24,000
VAT output tax £4,800

Watch out: the full amount goes to deferred revenue, not revenue.

2. Monthly revenue release

One month of the subscription above: £24,000 ÷ 12 = £2,000.

Account Dr Cr
Deferred revenue £2,000
Subscription revenue £2,000

3. Usage delivered but not yet billed (accrued income)

October overage of £3,500, invoiced in November.

Account Dr Cr
Accrued income £3,500
Usage revenue £3,500

Watch out: reverse it in November when the invoice is raised, or the revenue is counted twice.

4. Credit note for a cancelled annual contract

A customer cancels with 6 months left, under a contract that allows a refund. Credit note £12,000 + VAT.

Account Dr Cr
Deferred revenue £12,000
VAT output tax £2,400
Trade debtors £14,400

Watch out: only the unearned part comes off deferred revenue. The six months already recognised stay in revenue.

5. Customer payment received

Account Dr Cr
Bank £28,800
Trade debtors £28,800

6. Stripe payout: card sales, fees and a refund

Customers pay £10,000 of invoices by card (VAT already accounted for on the invoices). One customer, already given a credit note, is refunded £400. Stripe fees are £250. Payout to bank: £10,000 − £400 − £250 = £9,350.

Account Dr Cr
Stripe clearing (card payments received) £10,000
Trade debtors (invoices paid) £10,000
Trade debtors (refund paid against the credit note) £400
Stripe clearing (refund) £400
Payment processing fees (P&L) £250
Stripe clearing (fees) £250
Bank (payout) £9,350
Stripe clearing (payout) £9,350
Total £20,000 £20,000

Watch out: never post the payout as one net figure to revenue. Stripe clearing ends at zero.

7. Bad debt provision

Increase the provision by £5,000 for overdue debtors.

Account Dr Cr
Bad debt expense (P&L) £5,000
Bad debt provision (contra to debtors) £5,000

AI shortcut: give an approved AI tool a month's revenue journals and your deferred revenue schedule, and ask it to list any invoice posted straight to revenue where the service period runs beyond the month. A person checks each one against the contract.

Ten employees on £5,000 a month, 2026 to 2027 rates, pensions under a net pay arrangement. Gross pay £50,000, employer NI £6,875, employer pension £2,500. Deductions: PAYE £8,527, employee NI £2,675, employee pension £2,500. Net pay £50,000 − £8,527 − £2,675 − £2,500 = £36,298.

Account Dr Cr

Employer NI (P&L) £6,875
Employer pension (P&L) £2,500
Net wages control £36,298

Account Dr Cr
FX losses (P&L) £187.50
Trade debtors (USD) £187.50

19. Intercompany recharge

UK parent recharges £15,000 of shared costs to its US subsidiary. In the UK books:

Account Dr Cr
Intercompany receivable: US subsidiary £15,000
Recharge income (or cost recovery) £15,000

Watch out: the US subsidiary books the mirror entry in the same month, or the balances won't agree.

20. Clearing a suspense item

£2,300 receipt sat in suspense; it's identified as a customer payment.

Account Dr Cr
Suspense £2,300
Trade debtors £2,300

If you report under US GAAP (ASC 606)

The mechanics above are the same under US GAAP. Labels can differ: deferred revenue is often called a "contract liability" and accrued income a "contract asset" or "unbilled receivable". Contract cost capitalisation (entry 12) follows ASC 340-40 and share options (entry 16) follow ASC 718, with some policy choices that differ from IFRS and FRS 102.

Common mistakes and audit watch-outs

  • Debit and credit the wrong way round. If an accrual makes the P&L smaller, something's backwards.
  • Grossing VAT into the cost. For a fully VAT-registered business, recoverable VAT goes to input tax, not the expense line.
  • Accruals and accrued income that never reverse. Double-counting, every time.
  • Net payouts. Payment processor payouts posted net hide fees and refunds.
  • Journals without support. Every manual journal has a reason, a calculation and an approver.
  • Copying AI-suggested journals unchecked. AI can pick the wrong account or flip a sign. Check every line against your chart of accounts.

AI prompts to try

Use these only in AI tools your company has approved for financial data. AI drafts and checks; a person approves every journal.

1. Draft a journal. "Using this chart of accounts, draft the double entry for this transaction: [description, amounts, dates, VAT]. Show it as a Dr/Cr table and confirm it balances." Give it: your chart of accounts and the source document. Check: account codes, VAT and that the totals agree.

2. Review a batch. "Here are this month's manual journals. List any that don't balance, use rarely used accounts, have round amounts, lack a description, or were prepared and approved by the same person." Give it: the journal export with preparer and approver. Check: each flag against the support.

3. Explain a journal. "Explain in plain English what this journal does to the P&L and balance sheet." Give it: one journal. Check: the explanation matches your intent; it's a good test before approval.

4. Find missing reversals. "Compare last month's accruals and accrued income journals with this month's journals and list any that haven't been reversed." Give it: both months' journal listings. Check: each item in the ledger.

Key takeaways

  • Most SaaS month-end journals are the same twenty patterns.
  • Billing goes to deferred revenue; revenue is released as the service is delivered.
  • Accruals and accrued income reverse next month.
  • Payment processor payouts are grossed up: sales, refunds and fees separately.
  • Every journal balances, has support and has an approver.
  • AI can draft and check journals; a person approves them.

FAQs

Why does deferred revenue sit on the credit side?

It's a liability: the company owes the customer service it hasn't delivered yet. Liabilities increase with credits.

Should accruals include VAT?

Usually not. Accruals are typically booked net of VAT, because the VAT is claimed when the real invoice arrives.

Can AI post journals directly into the ledger?

Some tools can, but a common approach is for AI to prepare the journal and a person to review and approve it before posting, with the same approval rules as any other manual journal.
