How do I keep records of cash purchases with no card statement behind them?

Why does a cash purchase need a deliberate capture step?

Other payments leave a record someone else keeps. A card charge or bank payment appears on a statement, and software can pull it in: Intuit's help page on excluding downloaded bank transactions says that in QuickBooks Online you can connect your bank account and download transactions automatically.

Notes and coins pass through no such account. The bank statement shows a withdrawal as one sum, with nothing about what it bought, and a purchase from your own pocket appears nowhere in the business's records. A cash purchase not written down when it happens is simply missing, and no statement will prompt you later: the bank reconciliation still balances, because the withdrawal was recorded. Costs end up understated and the cash that went out is left unexplained.

That is also why delay does more harm than with a card. Months later a card statement still shows who was paid, how much and when; a cash purchase leaves only its receipt, if you kept it, and your memory. The IRS's Publication 583 advises that you record expenses when they occur and says that, generally, it is best to record transactions on a daily basis.

What should I record at the moment of purchase?

Capture each purchase in two places, before the day ends:

1. Mark the receipt. Ask for one every time. On it, write why the business needed the purchase, where the cash came from and, if the slip does not say plainly, what was bought.
2. Add a line to a running log. Keep one log for all cash purchases, in a notebook kept with the cash or in a spreadsheet. Each line carries the date, who was paid, the amount, what was bought, the business purpose, the source of the cash and a number also written on the receipt.

The log also covers a purchase with no receipt: Publication 583 says that if you cannot get a receipt for a cash payment, you should make an adequate explanation in your records at the time of payment. A line written at the parking meter is made at that time; one written weeks later is not.

Rebuilding a month from memory loses the small purchases first.

What must the record show to support the expense?

With no bank or card trail, the receipt and the log line carry all the weight. Publication 583 says your supporting documents should show the amount paid and that the amount was for a business expense, and that proof of payment of an amount, by itself, does not establish you are entitled to a tax deduction. So the record should show what was bought and that it was for the business, not only how much. Publication 583 also says that if the IRS examines any of your tax returns, you may be asked to explain the items reported; a purpose written at the time is what lets you answer.

A handwritten log is a legitimate format. Publication 583 says that, except in a few cases, the law does not require any specific kind of records, and that you can choose any recordkeeping system suited to your business that clearly shows your income and expenses.

Keep both halves. Publication 583 says supporting documents are important to keep because they support the entries in your books and on your tax return. A receipt with no entry leaves the books short; an entry with no receipt has nothing behind it.

Some spending carries its own list of elements. Publication 463 says that if you deduct travel, gift or transportation expenses, you must be able to prove certain elements of expense, and its Table 5-1 summarizes the records needed for each. It says you must generally provide a written statement of the business purpose of an expense, that the degree of proof varies with the circumstances, and that no written explanation is needed where the purpose is clear from the surrounding circumstances. A cash record for those expenses must meet that list too.

Why does the source of the cash decide the entry?

The debit is whatever was bought. The credit records where the money came from. Publication 583 describes double-entry bookkeeping as self-balancing because you record every transaction as a debit entry in one account and as a credit entry in another. For a cash purchase, the credit follows the cash:

Two mistakes follow from ignoring the source:

• Booking the withdrawal as the expense. A withdrawal only moves money from the bank into cash on hand. Treating it as the expense records spending before it happens, hides the actual purchases and leaves an expense no receipt supports. Publication 583 says that if you must write a check for cash to pay a business expense, include the receipt for the cash payment in your records.
• Recording your own cash as if the business paid. Crediting business cash for money from your pocket understates the business's cash and loses the amount the business owes you or your contribution.

If you pay for something out of the day's cash takings, record the full takings as sales and the purchase separately. Recording cash sales is its own question.

What are the entries for each source?

These entries follow one invented month for a small repair business. The left-in entry uses the pattern in Intuit's help page on paying business expenses with personal funds in QuickBooks Online, which puts the expense account on the first line of a journal entry and Owner investments on the second.

What if the cash came from the business account or a float?

On June 3 the owner withdraws 200.00 from business checking, then spends 38.50 on supplies, 12.00 on parking and 60.00 on a market stall fee:

If your software downloads bank transactions, categorize the downloaded June 3 withdrawal to Cash on hand instead of entering the two June 3 lines by hand. Record each bank transaction once.

If the cash came from a float already on hand, only the purchase lines apply.

What if I paid with my own cash and the business repays me?

On June 10 the owner pays 45.00 of their own cash for small parts, which the business owes them until it repays on June 30. Publication 583 describes liabilities as the debts of a business, so the credit goes to a liability account, Due to owner:

Intuit's personal-funds page says you can also wait for the repayment to show up in your bank feeds and categorize it there, here to Due to owner; do that or enter the repayment yourself, not both.

What if my own cash stays in the business?

On June 12 the owner pays 25.00 of their own cash for office supplies and leaves it in:

Should the business repay me, or should my cash stay in?

Both routes record the expense once, on the day you paid. They differ in what happens to your balance:

• Repaid. The business owes you the amount from the day you paid until it repays you; your owner balance does not change, and the business's bank balance ends lower by the amount. Never record the repayment as a second expense.
• Left in. Owner investments stays higher by the amount and the bank balance is untouched: the business has the expense, and you have put more into the business.

Decide the route when you record the purchase and note it on the log line, so a repayment is neither forgotten nor made twice. Intuit's personal-funds page notes that instead of Owner investments you may have a shareholder or partner investment account, and says to consult your accountant if you are not sure which to use. Recording owner contributions and draws in general is its own question.

If the person who spent their own cash is an employee, repaying them is an employee expense reimbursement, covered separately; Publication 463 says that how an employer treats such a reimbursement on the employee's Form W-2 depends in part on whether it has an accountable plan. If you are also your corporation's employee, ask your accountant whether the employee reimbursement rules apply before you repay yourself as an owner.

How do I show that no cash purchase is missing?

Completeness cannot be read from the records themselves, so check it against the cash at the end of each period: weekly if cash moves most days, monthly otherwise. Use the bank statement and a count of the cash, in this order:

1. Start from the cash on hand at the last count.
2. Add each withdrawal of business money into cash that the bank statement shows for the period, and any other business cash put into the float.
3. Subtract the logged purchases paid from business cash, and any cash paid back into the bank.
4. Count the notes and coins on hand and compare the count with the result.

Whoever runs the check should not be the person who spent the cash, and should see the bank statement through their own access and count the cash in person rather than accept a total. In a one-person business you are both, and the check still catches what you forgot to log.

In the June example, the cash box held 50.00 at the last count. Adding the 200.00 withdrawal and subtracting 110.50 of logged purchases leaves 139.50 that should be there. The count finds 129.75, so 9.75 left without a recorded purchase. A receipt for 9.75 of fasteners turns up in the van; it is logged and posted as a 9.75 debit to Supplies and a 9.75 credit to Cash on hand, and the count agrees.

A difference you cannot trace is not a purchase. Do not record an invented expense to close it; write the difference, date and count on the log and tell whoever prepares your accounts; if it was cash you took for yourself, record it as a draw, which is its own question. If you know what was bought but the receipt is gone, that is the lost-receipt question.

The check has one blind spot: cash from your own pocket never passed through the business, so a personal-cash purchase you forgot to log cannot be caught. For those, capture at the time is the only safeguard.

What changes when cash spending is routine or others spend it?

When cash purchases happen most days, move from ad-hoc capture to a routine: one float kept in one place, the log kept with it, and the tie-out run on a set day each week. Running such a fund, including its slips and top-ups, is a separate question. Where a supplier takes a business card or bank transfer, paying that way puts a statement line behind the purchase.

When staff or crew spend business cash, capture becomes a rule you enforce rather than your habit. Name one person accountable for each sum handed out; they bring back a receipt and log line for every purchase plus any unspent cash, and you, or a bookkeeper who did not spend it, post the entries and count the returned cash. Collecting receipts from employees and field crews is covered separately.

How do I keep the record readable for as long as it is needed?

A cash purchase's only support is often one slip, so a slip that fades is as good as none. Publication 583 says you must keep your business records available at all times for inspection by the IRS, and that you must keep your records as long as they may be needed for the administration of any provision of the Internal Revenue Code.

Scan or photograph each receipt the day you get it, while every figure is readable, and keep the paper with the log. Publication 583 treats a system that keeps records by electronic imaging as an electronic storage system and sets these conditions for one:

• All requirements that apply to paper books and records also apply to it.
• It must index, store, preserve, retrieve and reproduce the stored records in legible format.
• It must provide a complete and accurate record of your data that is accessible to the IRS.
• The original paper may be destroyed only once the system has been tested to establish that the paper records are being reproduced in compliance with IRS requirements for an electronic storage system, and procedures are established to ensure continued compliance with all applicable rules and regulations.

Publication 583 points to Revenue Procedure 97-22 for the details. Publication 583 also says that if your system does not meet these conditions, you may be subject to penalties unless you continue to maintain your original paper books and records in a manner that allows you and the IRS to determine your correct tax. Until it does, the paper itself has to stay readable; Publication 583 advises keeping supporting documents in a safe place.
