Chapter 6 — Recording Expenses and Paying Bills

Recording Expenses and Paying Bills

Expenses keep the business alive — every dollar of cost needs to be captured, categorized correctly, and paid on time. Missed expenses mean overstated profit and overpaid taxes; late-paid bills mean damaged vendor relationships and late fees that buy you nothing.

Bills vs. immediate purchases

Money leaves your business in two ways, recorded differently:

Bills (accounts payable). A vendor sends you a bill with payment terms. Record the bill when you receive it: debit the expense account, credit Accounts Payable. When you pay it: debit Accounts Payable, credit Cash.
Immediate purchases. You buy supplies with the business debit card or pay a contractor on the spot — no bill to wait for: debit the expense account, credit Cash (or the credit card liability, if charged).

Record it the day it happens. A receipt stuffed in a pocket for three weeks is an expense your books don’t know about. And keep the receipt: a $212 charge labeled “AMZN MKTP” could be office supplies, a client gift, or equipment — only the receipt tells you which account it belongs in. Photograph paper receipts; forward emailed ones to a “receipts” folder.

Reimbursements: owner and employee spending

Owners and employees constantly pay for business things with personal money — printer paper on a personal card, a toll out of pocket. These real expenses stay invisible unless someone records them.

The clean method is an expense report: receipts submitted with amounts and business purpose; the bookkeeper records the expenses (debit the expense accounts) and credits Owner’s Capital (owner paid, not being repaid) or a payable to the employee. When the business reimburses: debit the payable, credit Cash.

Reimbursements need the same documentation as any expense — a receipt and a business purpose, every time. And owner spending on personal items is never a business expense: that personal lunch goes to Owner’s Draw, not to “Meals.”

Petty cash: small money, real rules

Many businesses keep a cash box for minor purchases — parking, postage, pens. The system: establish a fixed amount (say $200), record the initial funding (debit Petty Cash, credit Cash), and require a receipt or slip for every disbursement. When the box runs low, count what’s left, total the receipts, and replenish to $200 — recording the expenses then.

Petty cash fails when it becomes a slush fund with no receipts: no slip, no reimbursement, no exceptions.

Expense vs. cost of goods sold

Not all spending is an “expense” in the reporting sense: cost of goods sold (COGS) is the direct cost of what you sold — a retailer’s wholesale product costs, a contractor’s installed materials, a restaurant’s food — rising and falling with sales; operating expenses are the costs of running the business regardless: rent, insurance, office salaries, advertising.

Why it matters: your gross margin — revenue minus COGS, divided by revenue — shows whether your core business model works before overhead. If a bakery’s gross margin is 40%, every dollar of sales leaves 40 cents to cover rent, wages, and profit. If you bury flour and sugar in “supplies expense” instead of COGS, your gross margin is meaningless. Rule of thumb: costs going directly into what the customer paid for are COGS; costs that keep the lights on are operating expenses.

Paying bills on purpose

Bill-paying should be a routine, not a reaction: a weekly bill-pay session gives you no late fees, no missed early-payment discounts, and a steady cash rhythm.

Take early-payment discounts: “2/10 Net 30” means 2% off if paid within 10 days — an enormous annualized return. Skipping it to “save cash” is one of the most expensive habits in small business.
Pay on terms, not early, otherwise. Paying a Net-30 bill on day 3 with no discount is giving away your cash float for free. Pay on the due date.
Prioritize by consequence. Payroll taxes and anything with penalties first, then key vendors, then everything else. Never let a tax payment slip to pay a vendor — the penalties are brutal and non-negotiable.
Keep business and personal separate. Commingled money makes every expense questionable and turns clean books into archaeology.

Autopay: convenience with guardrails

Autopay is great for fixed, non-negotiable bills — rent, loan payments, insurance — but bills that change need a human eye: autopay the fixed, review the variable. Let the $1,500 monthly rent go automatically, but review the electric bill, phone bill, and subscriptions before they pay — or at minimum the day after. That’s how an $80 phone plan quietly becomes $140, and how a cancelled subscription keeps charging for eight months. Keep a list of every autopay so an account change doesn’t trigger a cascade of failed payments.

A walkthrough: the weekly bill-pay session

Every Friday at 3 PM, our catering-business owner takes twenty minutes:

Opens the AP aging report. Three bills due next week: $900 to the food supplier (due Tuesday), $350 for insurance (due Thursday), $1,200 rent (due the 1st — autopay, confirmed funded).
Checks the cash position. $14,000 in checking; payroll ($4,800) hits Wednesday. After bills and payroll: $14,000 − $900 − $350 − $4,800 = $7,950 remaining. Comfortable.
Looks for discounts. The food supplier offers 2% for payment within 10 days — the invoice is 6 days old. Paying today saves $18. Paid.
Schedules the rest. Insurance scheduled for Thursday (on terms — no discount, no reason to pay early). Rent confirmed on autopay.
Files everything. Paid bills marked paid with confirmation numbers; receipts photographed and filed.

Twenty minutes, once a week: no late fees, one discount captured, cash position known. That’s the difference between managing cash flow and being managed by it.

The one-bill test

Pick any bill you paid last month and trace it end to end: the vendor invoice, the bookkeeping entry in the right account, the payment record with date and confirmation, the reconciled bank transaction. Trace all four in under two minutes and your expense system works; a missing link shows exactly where to fix it. Run this test monthly — a five-minute audit that keeps the expense pipeline honest.

Key takeaways

Record bills when received (debit expense, credit Accounts Payable) and pay them on a weekly routine — not when you remember.
Photograph or file every receipt immediately; a charge on the statement isn’t documentation by itself.
Record reimbursements with expense reports, receipts, and a business purpose; personal spending goes to Owner’s Draw.
Petty cash needs a fixed amount, a slip for every disbursement, and replenishment with recorded expenses.
Separate cost of goods sold from operating expenses so your gross margin tells the truth.
Take early-payment discounts; pay everything else on terms; never let tax payments slip.
