6450expenseNormal balance: Debitbusiness6450 — Supplies
Supplies is the account for consumables the business burns through to keep operating day to day — shop rags, cleaning supplies, small hand tools, safety gear — without any of it going directly into a specific customer job or product. That last distinction is what separates this account from Materials (5200), and it is worth applying consistently: if it gets delivered to or installed for the customer, it is Materials, not Supplies.
As an expense, it carries a normal debit balance. Where general office paper and pens land is genuinely a matter of preference — some businesses fold basic office supplies in here alongside shop consumables, others keep Office Expense (6250) strictly separate. Neither choice is wrong; consistency matters more than which one is picked.
A tool durable and expensive enough to keep and reuse across many jobs, rather than get used up, drifts toward Equipment (1500) instead — the same capitalization judgment call that shows up throughout this chart wherever a purchase sits between a quick consumable and a lasting asset.
What belongs here
- shop rags and cleaning supplies
- small hand tools used broadly rather than tied to one job
- safety gear that gets consumed or replaced over time
- general consumables that keep operations running day to day
What does not belong here
- materials that go into a specific customer job or product — Materials (5200), since they leave with the work
- paper and pens for the front office, if the business prefers to keep those strictly separate — Office Expense (6250)
- a durable, expensive tool kept and reused across jobs — Equipment (1500)

Common questions
- What is the real test for Supplies versus Materials?
- Whether the item is delivered to or installed for the customer as part of the job. If yes, it is Materials. If it is consumed internally to keep the business running, it is Supplies.
- Should office paper and pens go here or in Office Expense?
- Either works — some businesses group basic office supplies here with everything else consumable, others keep Office Expense strictly separate. Pick one and stay consistent.
