Cash Vault at Your Car Wash: Bank Deposits, Expenses, and Cash Audit (with Real Numbers)
Saturday you already reconciled the drawer: $18,440 sold, $8,000 out of the till at 2:00 p.m., $4,180 counted at close. Monday the question changes: where is the week’s cash? If the answer is “in a bag in the office” or “I think Juan deposited it”, you do not have treasury. You have a stack nobody can audit.
This guide follows the article on . There, cash arrives in the vault. Here you run what happens next: change fund, deposits to company accounts, expenses, and the audit figure — without touching the sold total.
Key insight
Audit cash = vault + drawer. If Monday the vault holds $14,280 and you left $3,000 of change, $17,280 in bills should be on site. Saturday is still sold at $18,440. A deposit does not erase sales; it moves cash from one place to another.
Three places, three jobs
At a car wash, cash is not “in the register”. It is in the drawer (operations), in the vault (safekeeping), or already at the bank (treasury). Mixing the three is the source of almost every shortage that “shows up” on Sunday.
Drawer (till)
Today’s cash for making change. Keep a low cap. Anything above that moves to the vault; it does not sit “just in case”.
Cash vault
Cash accumulated from mid-day pulls and the daily close. It persists overnight. From here you go to the bank or pay a cash expense.
Business bank account
The money is no longer on site. The deposit is recorded against the vault; Brilloo does not look up a live bank balance.
The same Saturday: from drawer to vault
We pick up the cash-cut numbers. At close you do not empty the till to zero: you leave a change fund for Sunday. The rest does go to the vault, together with the 2:00 p.m. pull.
| Line | MXN |
|---|---|
| Saturday completed sales | $18,440 |
| Cash collected | $12,400 |
| Partial cut at 2:00 p.m. → vault | +$8,000 |
| Cash counted at close | $4,180 |
| Change fund left in the drawer | $3,000 |
| Close transfer → vault | +$1,180 |
| Saturday vault (day’s credits) | $9,180 |
Close formula: counted − change fund = transfer to vault. Here: $4,180 − $3,000 = $1,180. Those $1,180 plus the $8,000 pull are $9,180 Saturday puts in the safe. Sold stays $18,440. Sunday’s float opens at $3,000 — not zero, not $12,000.
Monday: a deposit, one expense, and a figure you can actually audit
Assume the vault already held $22,500 from the prior week. Saturday adds $9,180. Monday you open at $31,680. You take $15,000 to the bank and pay $2,400 of chemicals against a category. None of that comes out of the drawer.
| Movement | MXN |
|---|---|
| Vault balance Monday open (prior week + Saturday) | $31,680 |
| Deposit to operating account | −$15,000 |
| Expense: chemicals (expense category) | −$2,400 |
| Vault balance at midday | $14,280 |
| Drawer (Monday change fund) | $3,000 |
| Audit cash (vault + drawer) | $17,280 |
If at midday $6,000 is “missing” from the safe, do not look for it in the sales report. Saturday still sold $18,440. The gap is in treasury: an unrecorded deposit, an expense paid from the till, or cash that never arrived from the pull. That is why the vault has to be a balance, not a shoebox.
What comes in and what goes out (without inventing the bank)
Brilloo’s cash vault is the branch’s persistent cash. It does not track your bank-account balance or ask for single-country fields: alias, bank name, account number, and holder if you want. Currency is the company’s currency.
Credits the vault
Same-day partial cuts and the close leftover (counted cash minus the change fund). Also a cash income that did not go through POS, if you record it.
Debit: bank deposit
You pick a company account (alias, bank, number) and the amount. It cannot exceed the vault balance. The day’s sold total does not move.
Debit: cash expense
Chemicals, parts, an emergency payment. Use a category the owner set up. This also cannot drive the vault below zero.
Rules that keep the balance from breaking
These are not software preferences: they are the minimum for a deposit to work as evidence the day someone asks about the week’s cash.
Sold total and cash are two books
Depositing $15,000 does not “lower sales”. It lowers on-site cash. If you mix the two figures, Saturday’s $18,440 looks like it “vanished”.
Audit cash = vault + drawer
When someone asks “how much cash is here?”, it is not only the till. It is the safe plus the change fund. That sum is what should exist physically.
The vault is not the bank
Brilloo does not read your account balance. The deposit documents that cash left the site toward an account you registered. Reconciling the bank statement is a separate step.
Never negative
You cannot deposit or spend more than the vault holds. If Monday you are $4,000 short for the deposit, the gap is in the week, not in the button.
7-day plan to stop keeping cash “in the office”
You do not need a corporate treasurer. You need a habit the manager can repeat on Monday without the owner on site.
Owner and manager say it out loud: drawer, vault, bank. Staff check out; they do not open the safe or record deposits.
Decide how much stays in the drawer at close (example: $3,000 MXN). The rest of counted cash goes to the vault. That fund is the next day’s opening float.
The owner registers at least one account (alias + bank + number) and two or three categories: chemicals, maintenance, miscellaneous. Generic fields; you do not need a single-country format.
Take to the bank only what is already in the vault. Record the deposit the same day, against the account. Do not pull a stack from the drawer “on the way to the bank”.
Pay a small supply from the vault, with a category and a note. If you pay for chemicals from the till today, tomorrow the cash cut “does not reconcile” and nobody knows why.
Vault + drawer = cash on site. Compare it with what you see. The week’s sold total lives in reports; this sum lives in the building.
Mistakes that break treasury
Paying suppliers from the till. The cash cut expects that cash; the expense makes it vanish and money “is missing” that actually left as bleach.
Thinking the vault balance is the bank balance. It is not. The bank is another book; the deposit only documents the outflow.
Leaving all cash in the drawer “until Monday”. The risk is not the cash cut; it is a full till on Sunday at 7:00 p.m.
Letting staff open the vault or record deposits. The person who rings sales does not audit themselves; the manager moves treasury.
Depositing without recording it, or recording a deposit that never left. The number on screen stops being evidence.
Trying to “fix” old weeks by posting backdated pulls. The vault accumulates the present; it is not a memory drawer.
How Brilloo runs this under Cash
In Brilloo, treasury lives in the dashboard Cash group — not mixed with counter POS or the Stripe subscription. Cash cuts and partial cuts credit the vault; deposits and expenses debit it. Staff check out; they do not move treasury.
Per-branch cash vault
Persistent balance. Pulls and the close transfer add; deposits and expenses subtract. It cannot go negative.
Accounts and categories
The owner sets alias, bank, and number, plus income or expense categories. The manager deposits and records expenses against that catalog.
Who can touch it
Owner on every branch; manager on theirs. Same permission as cash cut, pulls, packages, and voids. Staff stay out.
Reports that stay clean
Neither the deposit nor the vault expense changes the day’s sold total. Reports still show what you charged; treasury explains where the cash sits.
Operational tip: a $3,000 MXN float, a Monday deposit of what accumulated, and zero supplier payments from the till is usually enough. If cash “disappears” every week and the daily cut reconciles, the gap is between the safe and the bank — not in the POS.
