We already covered what a balance sheet is and why it’s worth checking every quarter. But a balance sheet only adds value if it’s both built correctly and read correctly — and in practice we see both fail, independently of each other. Here are the most common mistakes of each kind.

Reading it wrong

These are interpretation mistakes: the balance sheet itself is fine, but the wrong conclusion gets drawn from it.

  • Confusing profit with cash in the bank. A profit shown on the income statement doesn’t mean that money is available: it can sit entirely in invoices issued but not yet collected. The balance sheet is what shows you this, by looking at how much of current assets is actual cash versus pending collections.
  • Looking only at total assets. A large asset figure says nothing on its own if it isn’t compared against liabilities. A business with a lot of assets but also a lot of short-term debt can be in a worse position than one with fewer assets and less debt.
  • Not separating short-term from long-term. Having enough assets to cover total liabilities, but not enough to cover what’s due this quarter, is a real liquidity problem that a glance at the balance sheet total won’t reveal. You need to look at the current vs. non-current breakdown, not just the sum.
  • Comparing two balance sheets without accounting for context. A rise in stock before the busy season, or a spike in outstanding invoices after a month of strong sales, can look alarming and be perfectly normal. A balance sheet needs to be read alongside what you know about the business, not in isolation.
  • Treating equity as a single number without checking where it comes from. Positive equity built up from several years of retained profit is a very different situation from equity that only holds up because of the partners’ initial contributions. The final figure can be identical and tell very different stories.

Building it wrong

These are construction mistakes: if the base is wrong, any later reading starts from a flawed figure, however carefully it’s interpreted afterwards.

  • Recording on a cash basis instead of an accrual basis. An expense or income belongs to the period in which it’s generated, not the period in which it’s paid or collected. Booking a December invoice in the year it’s paid in January shifts the result from one year to another and distorts both balance sheets.
  • Leaving invoices or expenses unrecorded in the period they belong to. If the invoice for an expense already incurred hasn’t arrived yet, it still needs to be accrued; otherwise the liabilities side of the balance sheet is incomplete and the result looks better than it actually is.
  • Not reconciling the bank account before closing. A mismatch between what the accounts say and what the bank statement says, left unresolved, carries over into the balance sheet as an error that can take months to spot if nobody reconciles at each close.
  • Misclassifying current vs. non-current. The portion of a loan due within the next twelve months needs to move to current liabilities; leaving it all as non-current dresses up the business’s real liquidity.
  • Forgetting depreciation and provisions. Equipment, vehicles, or software lose value with use and time; not reflecting that on the balance sheet inflates the value of assets above what they’re actually worth today.

An example of the most common reading mistake

An online shop closes the quarter with €15,000 of profit on the P&L. The owner, looking only at that figure, decides to pay themselves €10,000 and reinvest the rest. But the balance sheet tells a different story: of the €18,000 in current assets, €13,000 is invoices to clients still unpaid, and only €5,000 is actually in the bank. If they withdraw €10,000 they don’t have in cash, they can’t pay suppliers that month, even though the business looks fine on paper. That’s exactly the reading mistake explained above, with real numbers.

Why we treat these separately

A poorly built balance sheet leads to a wrong reading even if whoever reads it is very careful — and a perfectly built balance sheet is still useless if nobody reads it well. That’s why we don’t just file your taxes: we prepare the balance sheet carefully and then sit down with you to explain what it says, so both sides of the process are covered.
