Opening Stock

This code records costs relating to opening stock. As a cost account, it normally carries a debit balance: debit entries increase the balance (recording new costs) and credit entries decrease it (for example, a credit note received from a supplier).

Real-world examples

Retail and wholesale

A retailer's opening stock is simply last year's closing inventory carried forward — valued at the lower of cost and net realisable value across everything held for resale. At the start of the year, a journal transfers that figure onto the P&L: a debit of £42,000 to 5200 (Opening Stock) and a credit of £42,000 to the stock account on the balance sheet. There's no VAT in this entry at all — it's a valuation journal, not a purchase, even though the figure originally derives from VAT-bearing purchases made in earlier periods.

Manufacturing

A manufacturer's opening stock spans three tiers — raw materials, work in progress and finished goods — and the WIP and finished-goods portions include a share of labour and production overhead absorbed into their valuation, not just the cost of materials bought in. The entry mechanics are identical to the retail example, but arriving at the £68,000 opening figure involves considerably more judgement than simply totalling goods held for resale.

Service business

A consultancy or agency holds no stock at all, so 5200 and 5201 stay permanently at zero on its balance sheet — there's nothing to value at either the start or end of the year, because the business sells time and expertise rather than physical goods.

Commonly confused with

Because code 5201 (Closing Stock) sits right next to this one in Purchases & Direct Costs, it's a common mis-posting target. Code 5200 is specifically for opening stock, while 5201 covers closing stock — similar in nature, but keeping them separate is what makes the purchases & direct costs section of your management accounts meaningful rather than a single lumped total.

What a mis-posting here costs you

Posting to the wrong cost code here won't change total cost of sales, but it will distort gross margin analysis by category, making it harder to see which input costs are actually rising.
