Most closing stock figures reach me the same way: a number in an email, typed on the evening of the year end. No count instructions, no raw sheets, no names against them. For a client holding real goods, that is the figure I trust least.
Disclosure up front: I work at Xero. Read this as field notes from someone who uses the platform daily, not a neutral review.
TL;DR: Closing stock moves profit and tax pound for pound, and in a small company nobody independently tests it. I am not auditing the figure. I am asking to see the goods and the raw count sheets before I put my name to it.
Why Closing Stock Is the Figure I Trust Least
Because it is the only material number in a small set of accounts with nobody on the other side. A bank balance has a statement behind it, debtors have invoices, creditors have supplier statements. Stock has one person walking round with a clipboard.
It moves the result directly. Overstate closing stock by £10,000 and profit rises by £10,000, costing £2,500 in corporation tax at the 25% main rate, or £1,900 at the 19% small profits rate on profits up to £50,000 (GOV.UK).
How Does a Stock Figure Actually Go Wrong?
Almost never through fraud. It goes wrong mechanically, and the same errors come round every year:
- Units sold months ago and never picked off the system, so the count includes things that do not exist.
- A delivery that landed on the last day, got counted, and was never entered as a purchase, so stock and creditors disagree.
- Lines valued at what the client hopes to get rather than what they cost, which is both wrong and flattering.
The one that catches multi-site clients: the same pallet counted twice, because each person assumed someone else had done that aisle.
What I Ask For Instead of Attending Every Count
Telling a sole practitioner to attend every stocktake is not advice, it is a fantasy. I ask for the count instructions beforehand rather than the total afterwards, because a client who has never been asked how they intend to count usually has not thought about it. I ask for the raw sheets with names and dates on them. I walk the stockroom when I can, and ask for a video walk-through when I cannot.
The check that earns its keep is the dullest. Gross margin, month by month, against last year, because a stock error nearly always surfaces as a margin that moved for no commercial reason.
It is a thinner version of what an auditor does. ISA (UK) 501 paragraph 4 requires attendance where inventory is material, unless that is impracticable, plus test counts on top (FRC).
Does an Inventory Module Fix This?
No, and it introduces a new problem. Perpetual tracking in Xero, QuickBooks or Sage is genuinely good, and the client who trusts the on-screen quantity because the software looks authoritative is the one who stops counting at all. The ledger records what it was told. It does not know what is on the shelf, the same gap as everything else you assume the platform is handling.
Am I Auditing Something I Wasn't Engaged to Audit?
No, and the standards draw that line. Most small companies never see an auditor: for periods beginning on or after 6 April 2025 a company can be exempt if it meets two of turnover up to £15m, balance sheet total up to £7.5m, and 50 employees or fewer (GOV.UK). ISRS 4410, the standard for compilation engagements, gives no assurance and does not require me to verify what management hands me (IFAC).
The same standard carries the other half. Where the information is incomplete, inaccurate or otherwise unsatisfactory, I have to raise it and ask for better, and where the client will not cooperate the endpoint is resignation. I am making sure I do not reach that point by surprise on a figure I have signed, the same instinct behind the jobs I won't take off a client's hands.
Frequently Asked Questions
How should a small business count stock at year end?
Write the instructions down before anyone starts. Say who counts which area, how goods-in and goods-out are frozen, and how damaged lines get flagged rather than quietly included. A summarised total is not a record of anything.
Does my accountant need to attend my stocktake?
If you are audited, your auditor must attend where inventory is material, unless that is impracticable. If you are not audited, nobody is required to attend, which is why I ask to look. I am not performing the count, I am satisfying myself the figure has some basis in the physical goods.
Should closing stock be valued at cost or selling price?
Cost, unless cost is higher than what you can actually get for it. FRS 102 paragraph 13.4 requires the lower of cost and estimated selling price less costs to complete and sell (FRC). Slow-moving and damaged lines are where this bites, and writing them down is the rule, not an admission of failure.
If you hold stock and your year end is coming up, I am happy to look at your count instructions rather than the total afterwards. Get in touch and we can work out what is proportionate.
