Crew Expense Cards for Construction: Per Diem, Lodging, and Job-Site Spend
Crew expense cards are payment cards issued to field crews and foremen for meals, lodging, and small job-site purchases, with spending limits, merchant category restrictions, and a job code attached to every transaction. They exist to replace two bad options, a foreman's personal card plus a reimbursement claim, or an envelope of petty cash.
Both bad options fail the same way. The employee carries the float, sometimes for weeks. The office receives a pile of receipts with no job codes on them. And nobody has any idea what was spent until it's all over. A card with rules on it solves all three at once, which is why this is one of the few field-finance problems with a clean answer. The wider payment picture for contractors sits in the construction payment management pillar.
Key Takeaways
A crew expense card replaces employee float and receipt chasing with controls applied before the money is spent.
The federal standard per diem rate is a useful anchor for setting card limits, even where your own policy differs from it.
Prepaid and credit-line crew cards solve different problems, and the choice comes down to how much control you need versus how much administrative load you can absorb.
Merchant category restrictions do most of the work that a written policy can't, because they act before the purchase rather than after.
Job tagging at the point of purchase is what makes crew spend usable for job costing later.
Card spend that doesn't reach the accounting system automatically has just moved the manual work rather than removed it.
What are crew expense cards and per diem cards?
A crew expense card is a company-issued card given to a field employee for work-related spend, configured with limits and merchant category rules appropriate to their role. A per diem card is a narrower version, loaded or limited to a daily allowance covering meals, lodging, and incidentals while traveling.
Construction crews use them for a predictable set of things. Meals on the road, hotel rooms for out-of-town jobs, small tools and consumables bought at a supply house when something goes missing, parking and tolls, equipment rental deposits, and job-site supplies that weren't on anyone's purchase order. The general category is covered in what a business expense card is; what's specific here is that field crews are mobile, often unsupervised at the moment of purchase, and buying from merchants nobody vetted in advance.
The scale of the problem is a function of headcount. Construction employed 8,359,000 people in August 2026 at average hourly earnings of $41.66 across a 39.5-hour week, according to the Bureau of Labor Statistics, and a meaningful share of that workforce travels to sites. Construction laborers and helpers alone held 1,674,400 jobs at a median wage of $46,680 in 2025, with employment projected to grow 6% through 2035 and about 137,000 openings a year per the Occupational Outlook Handbook. Asking people at that wage level to front hotel costs on a personal card is a retention problem as much as a finance one.
What does per diem cover for a traveling crew?
Per diem covers lodging plus meals and incidental expenses for each day away from the employee's regular work location. The federal reference point is the General Services Administration's rate schedule, which most private employers use as a benchmark even though they aren't bound by it.
For FY 2026, the standard CONUS per diem is $178 a day, made up of $110 for lodging and $68 for meals and incidentals, effective October 1, 2025 through September 30, 2026, with M&IE tiers running from $68 to $92 depending on location, per GSA Per Diem Bulletin FTR 26-01. Location-specific rates run well above the standard in high-cost metros, which matters if your crews work in them.
A note on tax treatment. Per diem arrangements have specific substantiation and accountable-plan requirements, and how an allowance is structured affects whether it's taxable to the employee. That's a question for your accountant rather than a card configuration decision, and it's worth settling before you set the card limits rather than after.
Who on the crew should get a card?
Give cards to whoever is authorized to spend, which usually means foremen and superintendents at minimum, and often every traveling crew member when per diem is involved.
The instinct to limit cards to supervisors is understandable and often counterproductive. A single card shared by a crew produces exactly the accountability gap the card was supposed to close, since no transaction is attributable to a person. Individual cards with tight limits are easier to control than one card with a loose limit, and they also remove the supervisor's role as the crew's involuntary bank. Guidance on who gets what sits in employee credit cards and in the policy framework covered by card controls and spend policies.
Which crew card fits your job site, prepaid or credit?
Both work, and they fail differently, so the choice depends on which failure mode you'd rather manage. Prepaid cards cap exposure absolutely and require someone to load them. Credit-line cards remove the loading step and rely on limits and rules to constrain spend.
Consideration | Prepaid or preloaded card | Credit-line crew card |
Control model | Hard cap at the loaded balance | Limits and rules enforced at authorization |
Exposure if lost or misused | Limited to the balance on the card | Limited to the configured limit |
Administrative load | Ongoing loading and balance monitoring | Set the limit once, adjust as needed |
Cash flow effect | Cash leaves when the card is loaded | Cash leaves at statement settlement |
Failure mode in the field | Declined at a hotel because the balance ran out | Overspend within the limit, caught after the fact |
Rebate participation | Generally none | Eligible on qualifying spend |
Credit check on the business | Not required | Usually required |
When does a prepaid per diem card make sense?
Prepaid fits temporary crews, short-duration projects, subcontracted labor, and any situation where you want a hard ceiling rather than a soft one. It also fits organizations that can't or don't want to extend a credit line, including newer companies without established business credit.
The practical drawback shows up at 9pm at a hotel front desk when an incidental hold exceeds the remaining balance and the card declines. Hotels commonly authorize more than the room rate to cover incidentals, and a per diem card loaded to exactly the daily rate will fail that authorization. Load with headroom for that reason specifically, because the cost of a declined card at a hotel is a call to the office and a crew member paying out of pocket anyway.
When is a controlled credit card the better fit?
A credit-line card fits permanent crews, longer projects, and any program large enough that daily loading becomes real administrative work. It also participates in rebate programs, which prepaid generally doesn't, and for a contractor moving meaningful field spend that's not trivial money.
The control question is answerable without prepaid's hard cap. A per-transaction limit, a daily or weekly limit, and category restrictions together produce a ceiling that's close enough to absolute for most purposes. The difference between the two models is less about control and more about who does the work, and an office manager loading fifteen cards every Monday is doing work that a well-configured credit card would do by itself. Physical versus virtual issuance is a separate question, covered in virtual card vs physical card, and the shared-account pattern in what is a ghost card.

How do you control and track crew spend?
Three control layers do nearly all the work, applied in this order. Amount limits first, then category restrictions, then job tagging. The first two prevent bad spend and the third makes good spend usable.
Policy documents don't belong on that list, which isn't a criticism of policy. A written rule that crew cards aren't for personal purchases is necessary and does nothing at the register. A merchant category block does.
How do spending limits and merchant category restrictions work?
Limits cap the amount and categories cap the type, both enforced at authorization by the card network before the transaction completes. A purchase outside the rules is declined at the terminal rather than discovered at month-end.
Limits come in three useful shapes. A per-transaction limit stops a single large purchase, a daily limit sized to the per diem stops accumulation, and a monthly limit provides the overall ceiling. Setting all three sounds excessive and isn't, because they catch different failure modes.
Category restrictions work off merchant category codes, and the mechanics are worth understanding because they're imperfect. Each merchant is assigned an MCC by its acquiring bank, and the assignment is sometimes wrong or surprising. A hotel with a restaurant might code everything as lodging, or a hardware store inside a larger retailer might code as a general merchandise store. The way merchant category codes are assigned means an allow-list needs testing against where your crews actually shop, not against where you assume they shop. Expect a week of adjustments after launch, and tell the crews that in advance so the first decline doesn't become a complaint.
The control case is stronger than a convenience argument suggests. The ACFE's Occupational Fraud 2026: A Report to the Nations found more than half of the 2,402 cases studied involved an internal control failure, with a median loss of $104,000 and a median scheme running 12 months before detection. Twelve months is a long time for a pattern to run in a petty cash process nobody reviews.
How do you tag crew spend to the right job?
Assign the job at or near the point of purchase, either by issuing the card against a specific project or by prompting the cardholder to select a job when the transaction posts.
Per-project card assignment is cleaner where it fits, because the job is implied and nobody has to remember anything. It stops fitting when a crew works two or three jobs in a week, which is common in specialty trades. The alternative is a prompt in a mobile app, and the design constraint there is brutal simplicity. A picker limited to the three jobs that crew is currently assigned to gets completed, and one showing the full project list does not.
Untagged field spend is the leak that shows up later as a job-cost problem, which is the same mechanism covered in construction job costing. The card program is where that leak either gets closed or doesn't.
How does crew card spend flow into your accounting system?
Through a transaction feed carrying the job code, cost code, merchant, amount, and receipt image into the construction accounting system, so the spend appears against the job without anyone re-keying it.
This is the step that determines whether the card program actually saved anything. A card with excellent controls and a monthly CSV export has moved the manual work from expense report assembly to file import, which is a smaller improvement than the pitch usually implies. Ask during an evaluation what the feed contains, how often it runs, and whether it carries the job and cost code or only the transaction.
Checks are the comparison worth making, since construction runs on them more than most industries. AFP's 2026 Payments Fraud and Control Survey Report found 76% of US organizations experienced attempted or actual payments fraud in 2025, with 58% reporting check fraud against 30% for ACH debits and 25% for wire transfers. A card transaction carries structured data and a dispute process; a check carries neither.
The economics make the reporting worth getting right. Construction spending ran at a seasonally adjusted annual rate of $2,157.6 billion in July 2026, 3.8% below the July 2025 estimate, per the US Census Bureau, while the producer price index for final demand construction rose 5.3% over the twelve months ended August 2026 according to the Bureau of Labor Statistics. Field spend visibility matters more when volume is soft and inputs are expensive.
The reimbursement process this replaces is documented in employee expense reimbursement, and the broader program view in expense management. Contractors also running cards for field purchasing will find the adjacent playbook in using credit cards to optimize construction spending in the field.
Issue crew cards with the controls already built in, with Corpay
The gap between a card program that works and one that generates a second kind of paperwork is whether the controls and the job coding are configured before the cards go out, rather than bolted on afterward.
Corpay issues crew cards with per-card transaction, daily, and monthly limits, merchant category restrictions set per role or per project, and job tagging captured at the point of purchase. Receipt capture happens in the mobile app, which is the only place a field crew will reliably do it. Coded transactions flow into your accounting system through 100+ ERP integrations including NetSuite, Sage Intacct, Business Central, and Acumatica, so field spend reaches the job-cost ledger without an import step. Most programs are live in weeks.

Frequently Asked Questions
What is a per diem card?
A per diem card is a payment card loaded or limited to a daily allowance covering an employee's meals, lodging, and incidental expenses while traveling for work. It replaces cash advances and reimbursement claims by putting the allowance directly on a card with a spending ceiling built in.
What does a per diem pay for?
Per diem covers lodging, meals, and incidental expenses such as tips and small travel costs for each day away from the employee's regular work location. It doesn't cover transportation to the destination, which is usually reimbursed or paid separately, and it doesn't cover work materials.
Who is entitled to per diem?
Entitlement depends on your company policy and any applicable contract or prevailing-wage requirements, since private employers aren't bound by federal per diem rules. Most contractors extend per diem to employees working far enough from home to require an overnight stay, with the distance threshold defined in policy.
How do crew expense cards work for construction crews?
Cards are issued to individual crew members or foremen with configured transaction, daily, and monthly limits plus merchant category restrictions. Purchases outside the rules decline at the terminal, and each transaction carries a job code either from the card's project assignment or from a prompt the cardholder completes.
How do you control what a crew can spend on an expense card?
Use three layers together. Amount limits at the transaction, daily, and monthly level, merchant category restrictions that allow lodging and meals while blocking off-policy categories, and receipt requirements enforced before approval. All three act at or near the purchase rather than at month-end.
What is the difference between a prepaid card and a business credit card for crew spend?
A prepaid card caps exposure at the loaded balance and requires ongoing loading; a credit-line card removes the loading step and constrains spend through limits and rules. Prepaid suits temporary crews and businesses without an established credit line, while credit cards suit ongoing programs and participate in rebates.
How do you track crew spend by project?
Either issue cards against a specific job so the project is implied, or prompt the cardholder to select a job when the transaction posts, limiting the picker to the jobs that crew is currently assigned to. The job code then travels with the transaction into the accounting system.
Do crew expense cards eliminate expense reports?
They eliminate most of the assembly work, since the merchant, amount, date, and often the job arrive automatically. What remains is confirming the business purpose and attaching a receipt where policy requires one, which is a minute of work rather than an evening.
