Running one car wash is demanding. Running five, ten, or fifty across different markets is a different challenge entirely. Every location orders detergents, towels, air fresheners, and equipment parts, often from whichever vendor has it in stock. Multiply that across a growing footprint, and spend slowly slips out of view. Which location is overpaying for cleaning equipment? Are two sites buying the same wax from different suppliers at different prices? Nobody can say for sure.

That blind spot is expensive. Car wash operators are navigating rising input costs at the same time the industry consolidates and competition intensifies. Spend management software gives multi-location operators a way to bring purchasing back under control, protect margins, and keep the customer experience consistent from one site to the next. This guide covers the pressures car washes face, what happens when spend goes unmanaged, the strategies that work, and five software options worth evaluating.

Key takeaways:

• Rising input costs and rapid consolidation make centralized spend control a margin priority for multi-location car washes.
• Unmanaged spend leads to rogue purchasing, inconsistent supplies, invoice overload, and weaker vendor negotiating power.
• Point-of-purchase control, where non-compliant orders are blocked before they're placed, beats after-the-fact expense tracking.
• Order.co unifies purchasing, approvals, and payments in one platform, so every car wash location buys from a pre-approved catalog and finance accelerates book close.
• Most operators need more than one tool — pairing a procurement platform with expense or card management software delivers end-to-end spend coverage.

Why managing spend has become harder for car washes

Car washes are growing fast, and that growth is putting new pressure on how operators buy. According to Rinsed's Q1 2025 Car Wash Industry Report, the industry recorded combined year-over-year same-store sales growth of 12.4%, with member revenue climbing 15.7%. Strong demand is good news. It also means more locations, more transactions, and more vendors to keep track of.

Cost is the immediate concern. In QC Capital's Q1 2025 industry report, operators named the rising cost of inputs, including chemicals, labor, and equipment, as a top-three concern, cited by 49% of respondents, just behind market saturation at 50%. When supply prices climb, every dollar spent at the point of purchase matters more.

The math shows why. In a breakdown of a modern tunnel express car wash generating $1.5 million in revenue, MMCG Invest estimated detergents at 5.22% of revenue, or roughly $78,300 a year, with labor at 15.82%. On a single site, those percentages are manageable. Across a portfolio of locations, small pricing differences and duplicate purchases quickly eat into margins.

Scale also changes the competitive picture. Larger operators can negotiate bulk discounts and access better terms, while the recent wave of consolidation makes economies of scale increasingly important. Operators who centralize purchasing turn their growing volume into leverage. Those who leave each site to buy on its own forfeit that advantage.

What happens when car wash spend goes unmanaged

No one wakes up one morning to discover their spend is out of control. It happens a location at a time. Here's where the damage tends to show up first:

• Rogue and duplicate purchasing: When each location picks its own vendors, the same detergent can be bought at three different prices, and no one has the volume to negotiate a better rate.
• Inconsistent customer experience: A customer who loves the towel finish and scent at one location expects it at every location. Fragmented buying makes that consistency hard to guarantee.
• Invoice overload: Dozens of vendors across dozens of sites generate a flood of invoices, straining accounts payable and pushing back month-end close.
• No spend visibility: Without a central record, finance leaders can't answer a basic question: how much did we spend last month, and on what?
• Weak negotiating power: Spend scattered across suppliers can't be pooled, so operators miss the bulk pricing their volume should earn.

Left unaddressed, these issues drag down the mid-teens net margins the car wash industry is known for. The good news is that every one of them is fixable with the right process and the right tools.

Strategies to manage spend across locations without sacrificing quality

Controlling spend doesn't mean cutting corners on the products that define your brand. It means putting structure around how those products get purchased. A few strategies stand out for multi-location car washes:

• Set approval workflows and budgets. Configure rules that route purchases to the right manager based on amount, location, or vendor. This prevents maverick spend before it happens rather than catching it after the fact.
• Automate accounts payable. Manual invoice matching and data entry consume hours your team could spend on operations. AP automation for car washes reduces that workload and speeds up month-end close.
• Control spend at the point of purchase. The most effective strategy stops non-compliant spend before an order is placed, rather than reconciling it weeks later. Dedicated spend management software makes the compliant choice the easy choice for every employee.
• Centralize purchasing. Route all buying through one system so every order, from every site, lands in the same place. Centralized purchasing pools your volume for better pricing and gives finance a single dashboard to track spend.
• Standardize the catalog. Build an approved product list so a site manager in one state orders the exact same towels, chemicals, and air fresheners as a manager three states away. Standardizing purchasing across locations protects brand consistency and removes guesswork.

5 spend management software options for car washes

A procurement platform might handle catalog control and approvals while an accounting tool manages the general ledger, or a card-tracking solution fills in visibility gaps that an expense tool doesn't cover. The goal isn't necessarily to pick one winner but to assemble the combination that delivers end-to-end spend management. Here are five options for your car wash team to evaluate:

Order.co — Best for multi-location procurement and spend control

Order.co is a procurement and spend management platform that unifies purchasing, payments, and spend control in one system built for multi-location operators. Rather than tracking spend after the fact, Order.co controls it at the point of purchase through a guided marketplace where every product is pre-approved to meet your budgets, sourcing needs, and approval policies. Finance teams get a single platform to manage payments instead of chasing paperwork from dozens of vendors, and Order.co AI helps identify lower-cost alternatives for frequently purchased items.

Dedicated features:

• Guided B2B marketplace with a unified, pre-approved catalog
• Custom multi-level approval workflows by amount, location, department, or vendor
• Centralized billing that simplifies vendor payments and reconciliation
• Direct integrations with accounting software like QuickBooks, NetSuite, Sage Intacct, and more
• Order.co AI surfaces lower-cost, in-stock alternatives for your most-purchased items

Benefits: Delivers consistent products across every location, reduces rogue spend, and dramatically lightens the AP workload. Finance leaders get full spend visibility in real time, and the centralized billing model means fewer invoices to process each month.

Considerations: Order.co delivers the most value for operators with meaningful indirect spend on physical goods across multiple sites, rather than businesses focused only on employee travel and expense reimbursement.

Express operator Spark Car Wash shows the model in action. As the car wash scaled from 15 locations toward 95+, it used Order.co to standardize purchasing and ensure every site orders the same approved supplies. "It creates a good continuity where everyone gets the same customer experience no matter where they go when they visit a Spark," said Marketing Manager Kate Marinelli.

PayEm — Best for corporate card controls and lean finance teams

PayEm is a spend management platform that combines corporate cards, purchase order workflows, and supplier payment automation in one system. Finance teams can issue virtual and physical cards with preset spending limits and merchant restrictions, while AI-powered invoice processing handles coding and routing automatically. The platform syncs directly with ERPs like NetSuite, so approved transactions flow into the general ledger without manual data entry.

Dedicated features:

• Virtual and physical corporate cards with per-card spend limits and merchant controls
• Purchase order creation with configurable approval workflows
• AI-powered invoice processing with automatic GL coding
• Real-time budget-vs.-actual tracking across departments
• Direct ERP sync with NetSuite and other accounting systems

Benefits: Gives lean finance teams proactive control over card-based and invoice-based spend without enterprise-level complexity. Real-time budget tracking and automated approval flows reduce manual work significantly, and card-level controls prevent overspending before it happens.

Considerations: PayEm works well for small to mid-market businesses managing corporate card spend and supplier invoices. Car wash operators with heavy indirect goods procurement across many locations may need to pair it with a platform that offers a pre-approved product catalog and consolidated vendor billing.

Procurify — Best for mid-market procurement workflows and budget tracking

Procurify is a procurement and spend management platform designed for mid-market teams that need structured purchasing workflows without enterprise-level complexity. It covers the full intake-to-pay cycle, from purchase requests and approvals through to AP automation and payment, with an AI-powered spend analyst that answers questions about your data in real time. The platform is built to get teams off spreadsheets and into a centralized system quickly, with an interface that keeps adoption friction low.

Dedicated features:

• Purchase request and purchase order workflows with configurable approval routing
• AI-powered intake that auto-fills line items and codes from vendor quotes
• AP automation with three-way matching and integrated payments
• Real-time budget tracking with committed spend visibility
• AI spend analyst for on-demand reporting and cost-saving insights

Benefits: Gives growing teams a clear procurement workflow from request to payment, with real-time budget visibility that accounts for committed spend, not just what's already been paid. Quick adoption thanks to an intuitive interface, and the AI spend analyst helps finance leaders spot savings without building custom reports.

Considerations: Procurify covers procurement and AP well for mid-market teams, but it doesn't offer a pre-approved product catalog or centralized vendor billing the way a platform like Order.co does. Multi-location car wash operators with heavy physical goods spend may find they need that additional layer of catalog control.

Airbase — Best for unified non-payroll spend management

Airbase brings AP automation, corporate cards, and employee expense management together on one platform. Its guided procurement feature routes purchase requests through stakeholder-specific approval chains, and every transaction—whether paid by card, PO, or reimbursement—feeds into a single real-time view of non-payroll spend. Budget owners can track spending in real time by department or cost center, so overages are caught before they become a problem.

Dedicated features:

• Guided procurement intake with no-code approval workflows
• AP automation with bill creation and payment scheduling
• Virtual and physical corporate cards with per-card spend limits
• Automated GL coding with machine learning
• Real-time budget tracking by department or cost center

Benefits: Consolidates card spend, invoices, and reimbursements into one reporting layer so finance teams see all non-payroll spend in real time. Strong budget controls help prevent departmental overspending before it happens.

Considerations: Airbase is built for broad corporate spend management rather than multi-location indirect goods procurement specifically. Car wash operators who need a pre-approved product catalog and vendor-consolidated billing for physical supplies would likely pair Airbase with a dedicated procurement platform.

Sage Expense Management (formerly Fyle) — Best for real-time card transaction tracking

Sage Expense Management, formerly Fyle, is an expense management platform built around real-time credit card feeds and automated receipt-to-transaction matching. It integrates directly with Visa, Mastercard, and American Express card networks, so finance teams see every card swipe the moment it happens rather than waiting for a bank feed to sync days later. Employees can submit receipts by text message, email, or mobile app, and the platform automatically matches them to the right transaction.

Dedicated features:

• Real-time credit card feeds direct from Visa, Mastercard, and American Express networks
• Instant text notifications on card swipes with one-step receipt submission
• Automated receipt-to-transaction matching and credit card reconciliation
• Custom spend policy controls that flag or block out-of-policy transactions automatically
• Multi-level approval workflows configurable by amount, department, or expense type

Benefits: Gives finance teams immediate visibility into card-based spend across the organization, cuts down on receipt chasing, and automates credit card reconciliation. AI-driven policy checks catch duplicates and policy violations in real time, reducing compliance risk without adding manual review steps.

Considerations: Sage Expense Management excels at tracking and reconciling card-based employee spend, but it doesn't manage the procurement side of purchasing. Car wash operators who need to control what gets bought through a pre-approved catalog or manage purchase orders for physical supplies would pair it with a procurement-focused platform.

Questions to ask during a spend management software demo

A demo should prove the platform fits how car washes actually buy. Bring these questions to ensure the platform(s) you choose fit your needs:

• How does the platform prevent non-compliant purchases before an order is placed, not just report them afterward?
• Can I build a pre-approved catalog so every location orders the same supplies?
• How do approval workflows adapt to different dollar amounts, locations, and managers?
• Does it sync with my accounting system or ERP?
• Will it work with the local and national suppliers my locations already use?
• What visibility will finance leaders have into spend across all sites in real time?
• Who resolves vendor issues like returns, refunds, and order mistakes?

If you need a framework for scoring and comparing vendor responses side by side, this procure-to-pay platform buyer's guide covers the evaluation criteria that matter most for multi-location operators.

Why Order.co is a strong fit for multi-location car washes

You know the pressure of keeping quality consistent while margins tighten and locations multiply. A customer who trusts your wash expects the same clean, the same scent, and the same finish whether they visit your flagship or your newest site. Delivering that consistency starts with what your team buys, and that's exactly where spend runs off the rails when purchasing is left to each location.

Order.co controls spend at the point of purchase, so the products flowing into every location are consistent by default. As a result, your team spends less time chasing paperwork and vendors, and more time delivering the experience that builds customer loyalty. For operators comparing tools, that combination of control, consistency, and visibility is what separates a platform that records spend from one that manages it.
