# Petty Cash Cards For Small Businesses: Limits And Rollout Learn how a corporate card program works, how it differs from business cards, and what growing companies should evaluate before choosing one. **URL Source:** https://www.brex.com/spend-trends/corporate-credit-cards/petty-cash-cards --- How small businesses replace petty cash with corporate cards ### Key takeaways - Petty cash cards can make small business spending easier to track. Card purchases can show up as employees make them, so owners may not have to wait for a month-end count to see what the company spent. - Card types differ in who carries the risk. Business credit cards, corporate cards, prepaid cards, debit cards, and employee reimbursements each can handle liability and personal guarantees differently, which shapes what makes sense as a petty cash alternative. - Many companies phase out petty cash gradually rather than all at once. A short overlap period, a clear announcement to employees, and a plan for misused or lost cards are common parts of the switch. - A few purchases may still not fit a card. Some expenses work better through reimbursements or a small cash fund, even after cards cover most everyday spending. ### Introduction At a 15-person startup, petty cash might live in a lockbox in the office manager’s desk. It can be used to cover printer ink, snacks for a team meeting, and the occasional lunch order. But that spending may not be visible to anyone until someone counts the cash and turns in the receipts at month-end. Until that count, missing cash can go unnoticed, and it can become difficult to tell where the money went. Employees may feel the friction too, since they may have to ask for cash before each purchase or pay out of pocket and wait to get paid back. Cash kept on site can also be a target for theft. In the [ACFE's 2026 Report to the Nations](https://www.acfe.com/fraud-resources/report-to-the-nations), a global study of occupational fraud, cases involving theft of cash on hand had a median loss of $20,000. Replacing petty cash with [corporate cards](https://www.brex.com/spend-trends/corporate-credit-cards/how-do-corporate-credit-cards-work) can change that. Each purchase leaves a record when it happens, so month-end starts from a list of transactions, instead of a cash count. We compare petty cash with other options below, including employee reimbursements, and explain what a petty cash card is. We also cover the card controls companies commonly use, how they roll cards out to employees, which purchases tend to stay in cash, and what closing the petty cash fund involves. Our focus is small teams handling petty cash management, including companies without a dedicated finance department. We suggest you use this guide along with your professional advisor when making business decisions. ### What are the alternatives to petty cash? The main alternatives to petty cash are employee reimbursements, business credit cards, corporate cards, prepaid cards, and debit cards. Each one can change who pays up front, who carries the risk, and how much control a company has over each purchase. The table below breaks down how these petty cash alternatives compare. Liability is one of the biggest differences between card types for an owner. A business credit card often requires a [personal guarantee](https://www.brex.com/spend-trends/corporate-credit-cards/personal-guarantee), which generally makes the owner personally responsible for the balance if the business can’t pay, depending on the card agreement. Corporate cards typically put that responsibility on the company instead. [Prepaid business cards](https://www.brex.com/spend-trends/corporate-credit-cards/prepaid-business-credit-cards) and debit cards draw on the company’s own money, so a personal guarantee usually doesn’t come into play. The Brex corporate card doesn’t require a personal guarantee, and for approved companies, Brex sets credit limits based on the company’s financial profile, including revenue, amount raised, or cash balance, rather than the owner’s personal credit score. With [employee reimbursements](https://www.brex.com/spend-trends/expense-management/expense-reimbursement), employees pay with their own money and submit receipts to get paid back. That setup handles the occasional out-of-pocket cost, but it can leave employees fronting company expenses and waiting on approval. As a result, many companies keep reimbursements for one-off costs and move routine purchases onto cards. Among small teams moving off a cash box, the choice often narrows to corporate cards or prepaid cards, since both put a limit on each card before anyone buys. Prepaid cards stop at whatever amount was loaded, which may suit a fixed budget, but someone typically has to reload them, and some teams hold back the next top-up until receipts come in. Corporate cards can set limits without loading money in advance, though the issuer reviews the company before extending credit, so the better fit usually depends on how much the team spends and how it wants to fund the cards. ### What is a petty cash card? A petty cash card is a company card that employees use for the small, everyday purchases petty cash normally covers. It’s often a corporate or prepaid card that enforces spending limits at the moment of purchase, so employees can pay for a client coffee, a rideshare, or other day-to-day expenses directly. Larger organizations often use a similar tool called a [purchasing card, or p-card](#), which applies set limits to routine business buying. Some banks sell a prepaid product under that name, while other companies use a corporate card for the same job. Either way, the card can swap the cash box and paper voucher for a transaction record tied to one cardholder. Here’s how petty cash and corporate cards compare side by side. ### What petty cash card format fits each type of purchase? Physical petty cash cards typically suit employees who pay in person, and virtual petty cash cards often suit online orders and digital wallets. At a hardware startup, a technician buying parts at a supply counter might tap or hand over a physical card. On the other hand, an office manager buying supplies from an online store could use a [virtual card](https://www.brex.com/spend-trends/corporate-credit-cards/virtual-business-credit-card) instead, a 16-digit card number that exists only in digital form and can often be added to Apple Pay or Google Pay. Some teams issue both formats, giving each cardholder whichever card fits the purchases they make. A startup team working a trade show, for example, might carry physical cards for parking and booth materials while booking shipping online with a virtual card. A virtual card added to a phone wallet can often be used at a store register too, so some small teams skip physical cards for employees who rarely buy in person. ### How do petty cash card controls replace cash box rules? Card controls can replace petty cash rules by building each rule into the card itself, so a purchase that breaks one can be declined before any money moves. That can also ease a common worry for owners, who may assume handing out cards makes overspending easier than handing out cash. Owners with that worry often start with low per-card limits and raise them once they see how each person actually spends. The settings vary by issuer, but four controls show up in many card programs. - Spend limits can stand in for the cash in the box. Many programs set a single-purchase and monthly limit on each card, so a technician can buy parts up to a set amount on the spot. - Merchant category restrictions can replace the list of banned purchases. Each seller carries a merchant category code, or MCC, that classifies its type of business, and some programs decline purchases from blocked categories. - Receipt capture can replace the envelope of paper receipts. Cardholders can often snap a photo of an [expense receipt](https://www.brex.com/spend-trends/expense-management/expense-receipts), text it in, or forward ones received by email. Receipts arrive as purchases happen, which can mean less follow-up before close. - Independent review can replace the monthly cash count. Many companies build [corporate card management](https://www.brex.com/spend-trends/corporate-credit-cards/corporate-credit-card-management) around someone other than the cardholder looking over card activity on a regular schedule. At a small business, that’s often the owner or an outside bookkeeper, who checks each transaction against its receipt. Once each control sits on the card instead of in a binder, the rules come with the card, so a new hire doesn’t have to learn them secondhand. On Brex, admins can use [spend limits](https://www.brex.com/platform/spend-limits) to set a maximum transaction amount that auto-declines anything above it and to restrict a limit to virtual cards only. Brex customers can also have in-policy expenses approved automatically, with anything that needs a closer look flagged for review. ### How do companies issue petty cash cards to employees? Companies typically issue petty cash cards by deciding who needs one, setting a limit for each role, and making sure every cardholder knows the rules. At a small business, the owner often approves each card, and a short written [corporate credit card policy](https://www.brex.com/spend-trends/corporate-credit-cards/corporate-credit-card-policy) covers what the card can and can’t pay for. Cards usually go to the people who already buy things for the company, like the office manager, a technician, or whoever runs events. For companies with more than one office, a card for each location or team often replaces the cash box at each site. A growing company with hubs in two cities, for example, might give each office manager a card for that office’s day-to-day costs, which can keep spending traceable to the location that incurred it. Each card carries its own limits, so one office’s spending doesn’t eat into another’s. A [corporate card program](https://www.brex.com/spend-trends/corporate-credit-cards/corporate-credit-card-program) set up this way also lets the owner compare locations side by side at month-end. Getting cards into people’s hands doesn’t take long. Card platforms commonly issue virtual cards right away, and physical cards typically arrive by mail within a few days. When a purchase needs more than a card allows, many platforms let the cardholder request a higher limit, which the owner can approve from a phone instead of opening the cash box. Family & Children’s Place, a nonprofit in Louisville, describes raising a spend limit in three minutes while employees waited in a hotel lobby. When someone leaves or changes roles, companies that [give business credit cards to employees](https://www.brex.com/spend-trends/corporate-credit-cards/how-to-give-business-credit-cards-to-employees) can turn off or reassign that person’s card so access stays current. ### Which purchases don’t fit a petty cash card? A few purchases may nott fit a standard employee card, usually because the person getting paid can’t take a card or isn’t part of the company. These exceptions tend to be small and infrequent, so they may not justify keeping a full cash box. Common examples include the following. - Cash tips while traveling, like hotel housekeeping or a valet, since some expense policies still pay these in cash - Payments to people outside the company, such as a startup paying user research participants, which some companies handle with a reloadable prepaid or debit card instead of cash - The occasional cash-only vendor, like a local supplier or market stall that doesn’t take cards Some of these purchases work fine as reimbursements, with an employee covering the cost and submitting a receipt afterward. Companies that keep a few exceptions often list them in the written [procurement policy](https://www.brex.com/spend-trends/procurement/procurement-policy) that covers their cards, along with who’s responsible for each one and a spending cap. Some also hold onto a small cash fund just for these purchases and trim the list each time they update the policy. ### How do companies phase out a petty cash fund? Companies commonly phase out petty cash gradually, starting with one team or location and running cash and cards side by side for a short window. A pilot at one location also gives the owner a few weeks of real spending to set limits against before the rest of the company switches. As more people get cards, the cash fund shrinks until it covers only the few purchases that still need cash. For employees, one of the biggest changes may be no longer having to request cash. They pay with their company card and capture the receipt when they buy, instead of holding onto paper copies until the end of the month. On many platforms, that receipt attaches to the transaction and feeds [automated expense reporting](https://www.brex.com/spend-trends/expense-management/automated-expense-reporting). Companies usually announce the switch with a short message, a copy of the updated petty cash policy, and a date after which the cash box no longer covers routine purchases. Employees also get one person to go to with questions, often the owner or office manager at a small business. During the overlap, the cash box still covers purchases for anyone who doesn’t have a card yet. The overlap tends to end once everyone who needs a card has one and the company has settled which exceptions stay in cash. At that point, the company counts whatever cash remains and closes the fund. ### What happens if a petty cash card is misused or lost? Even with controls in place, a card can end up used for the wrong purchase or go missing. Most cases fall into one of three situations, and each has a fairly standard response. Here’s how companies commonly handle each one. - **An accidental personal charge:** This often happens when an employee mixes up a company card and a personal card at checkout. Either the employee flags it or the regular review of card activity catches it, and many companies have the employee repay the amount. - **Intentional misuse:** An admin can lock or cancel the card right away, and the company handles the rest under its written policy. - **A lost or stolen card:** Turning the card off can stoop new purchases while a replacement is on the way. On Brex, cardholders and admins can lock a card at any time, and an employee can’t unlock a card an admin has locked. Brex may also lock a card automatically after an unusual transaction and notify the cardholder by text or push notification. Depending on why the card is being replaced, a replacement card can keep the same number with a new security code and expiration date, so recurring charges can continue. ### What does closing a petty cash fund involve? Closing a petty cash fund typically involves confirming that the cash still in the box plus any unrecorded receipts adds up to the amount the fund started with, and moving what’s left back into the company’s operating account. Many owners hand this part over to their bookkeeper or accountant, who can also confirm how the closing is recorded. Some companies also keep a short record of who managed the fund and when it closed, so it’s easy to find later. If the person who handled the cash box leaves the company, many businesses close or hand off the fund before that person’s last day. Turnover is also a common reason companies make the switch in the first place, since the receipts for a departing manager’s cash spending can be hard to track down once that person is gone. That timing may matter most at small businesses, where one person often holds the box, the key, and the receipts. As the cash fund closes, the company can set up its new cards in its accounting software, often through [accounting integrations](https://www.brex.com/product/integrations) that sync each transaction. Many companies give each card its own subaccount under one parent account, so spending shows up by cardholder while the totals roll up in one place. Exact account treatment can vary by organization, so many companies confirm their setup with their accountant. ### How Brex helps small teams replace petty cash Replacing petty cash with cards gives a small team rules that apply on their own instead of depending on whoever holds the cash box.

Petty cash cards tend to work well for small businesses whose employees regularly make small purchases, like postage, courier fees, or software subscriptions. A small team may not need a finance department to run a card program, since the owner can approve cards and review spending directly. For the occasional purchase a card can’t cover, many companies keep reimbursements or a little cash on hand. ### How long does it take to switch from petty cash to cards? Getting cards to employees is usually the quick part, with virtual cards available quickly and physical cards following by mail typically within days. The overall timeline depends more on the transition itself, like how long the company runs cash and cards simultaneously and when it sets a cutoff date for routine cash purchases. ### How do companies set spending limits on petty cash cards? Many companies base card limits on what the petty cash fund used to pay out, including the size of typical purchases and how much the fund covered in a month. Limits often vary by job responsibility, since an office manager buying supplies and a technician buying parts make different routine purchases. Some companies revisit those [card limits](https://www.brex.com/spend-trends/corporate-credit-cards/business-credit-card-limits) periodically against actual spending and adjust them as needs change. ## Related Articles ### [Business credit cards that don't report to personal credit](https://www.brex.com/spend-trends/corporate-credit-cards/business-credit-cards-that-dont-report-to-personal-credit) Protect your personal credit with business cards that report only to business bureaus.
