Examples
You issue 80 ownership certificates
You incorporate a stove shop as an S-corp on February 11. You deposit $6,200 at the bank and issue yourself 80 formal stock certificates. That issued ownership is stock: the shares the corporation put out, and the total of those shares is capital stock. Debit Checking $6,200 and credit Capital Stock $6,200; each certificate is one share. You see the stock line on the balance sheet under equity, and in QuickBooks Online you code the deposit to equity, not to income.
Shop restock is not ownership stock
You run a hardware store. On August 3 you tell your bookkeeper the $1,850 bill from a cordage supplier restocked the stock, meaning goods on the floor. They credit Capital Stock $1,850, but stock in this dictionary is ownership shares evidenced by certificates, not merchandise inventory. Debit Inventory $1,850 and leave the equity stock line alone. If you treat a restock as stock, the balance sheet invents new owners and hides goods you can sell.
Why it matters
Stock in this dictionary is the ownership shares a corporation has issued, shown by formal certificates; the total of those shares is capital stock. You will not post this most months; it shows up when you form the entity, issue certificates, or add a stockholder, then sits in equity until the next issuance. A share is one unit, and mix stock with merchandise inventory and a restock of goods looks like new owners while the balance sheet hides what you can sell. Keep the stock line for certificates you actually issued, and keep shelf goods in inventory.
