An express car wash lives or dies on throughput. Cars move through the tunnel in minutes, margins on each wash are thin, and the whole business model depends on one thing: consistency. A customer who loves the wash at your flagship site expects the same clean, the same scent, and the same shine at every location they visit. That expectation is part of the product.

Keeping it consistent gets harder with every location you open. Site managers order supplies from whoever has stock, invoices pile up from dozens of vendors, and finance can't see what's being bought where until the bills arrive. Growth magnifies every one of these frictions.

This guide provides a roundup for operators evaluating procurement software for car washes. It covers what these tools do, who each one fits, the criteria worth weighing before you buy, and how one multi-location express car wash business put a platform to work as it scaled.

Key takeaways:

• Standardized purchasing is how multi-location car washes keep the customer experience consistent across every site.
• Chemical and consumable costs add up fast — small per-unit price differences across locations compound into real margin impact at scale.
• The right procurement software centralizes ordering, enforces approvals, consolidates vendors, and gives finance real-time spend visibility.
• Five platforms are compared: Order.co, Precoro, Ecotrak, Fraxion, and SAP Ariba — each with a different best-fit profile.
• Spark Car Wash uses Order.co to standardize purchasing as it scales from 15 locations to 95+ across the Northeast.

The procurement pressures car washes face as they scale

The U.S. car wash market hit roughly $36 billion in revenue in 2025, and express tunnels account for about 51% of that, according to Persistence Market Research. The format is growing at a 6.1% CAGR, and consolidation is accelerating alongside it. The top operators now run 300 to 500+ locations each, with private equity fueling acquisitions across the country. That growth puts real pressure on how purchasing gets managed.

Every car wash chain runs into its own set of procurement challenges as it scales. Understanding what makes these challenges distinct from other multi-location businesses is what turns a general purchasing strategy into one that actually works:

• Consistency drives membership revenue. Membership and subscription revenue grew 15.2% year-over-year in Q2 2025, according to Rinsed, and car washes with 4,000+ members convert retail customers at 15.6% compared to under 3% for those with fewer than 2,000 members. That conversion depends on delivering the same quality at every site. When managers order independently, products vary, and the experience customers are paying to repeat starts to change.
• Consumable spend is constant and adds up fast. Chemical costs alone average $0.40 to $0.65 per car washed and represent roughly 8.5% to 10% of a car wash's total cost basis, according to Car Wash Advisory. For an express site doing $1.5 million in annual revenue, that translates to around $78,000 a year in detergents alone.
• Decentralized, on-site buying creates blind spots. Ad hoc ordering produces maverick spend, inconsistent pricing, and no central record of what was purchased. When each site manager picks their own suppliers, HQ has no way to compare what's being bought where.
• Vendor sprawl multiplies with every new site. Each new location tends to add its own local suppliers, and every supplier means more invoices, more payment terms, and more things to reconcile. For chains adding 10, 20, or 40+ locations a year, this sprawl grows quickly.
• HQ visibility stays limited until it's too late. Finance often can't see what's being bought where until invoices land, which makes budgeting and cost control reactive instead of planned.
• Expansion multiplies every challenge. The largest express operators now run 300 to 500+ sites. Going from 10 locations to 100 or more means each of these procurement frictions scales with you, unless the buying process is standardized first.

The pattern is clear: as a car wash chain grows, unmanaged purchasing puts pressure on both margins and the consistent experience that drives membership retention. The right software addresses these challenges before scale makes them harder to fix.

How procurement software solves these pressures

The good news is that none of the pressures outlined above are inevitable. Procurement software exists to address each one with a specific capability. When you map the right tool to the right problem, the result is stronger consistency and a purchasing process that scales alongside your locations instead of working against them.

• Centralized purchasing puts one catalog and one process across all locations, so every site orders the same approved products.
• Approval workflows route spend through controls before money leaves your business, which eliminates rogue orders at the source.
• Spend visibility and reporting give finance a real-time view of what each location spends, broken down by category and vendor. Budgeting becomes proactive.
• Vendor consolidation manages many suppliers through a single platform, and in some cases a single invoice, which tames vendor sprawl.
• Product standardization locks in shared product lists so each site reorders the exact same SKUs. This is the mechanism behind a consistent customer experience.

Standardizing purchasing first is what lets your multi-location car wash grow without letting quality drift. The underlying principle is centralized purchasing, where HQ sets the rules, catalogs, and approval paths that every location follows rather than letting each site figure it out on its own.

What to look for when choosing procurement software for a car wash

The best procurement software for a car wash is the one your site managers will actually use. Before comparing tools, set your criteria. A platform built for a 500-person procurement department may be the wrong fit for a shift lead reordering towels between wash cycles. Weigh each option against what your business — and the people doing the ordering — actually need:

• Multi-location and multi-entity support: Can the tool manage separate sites, budgets, and approval chains under one roof?
• Ease of adoption for non-procurement staff: Site managers, not buyers, will use it daily. The interface should be simple enough to learn in a day.
• Approval flexibility: Look for custom, multi-level approval chains based on dollar amount, location, or vendor.
• Spend reporting: Real-time, line-level visibility by location, category, and supplier.
• Vendor consolidation: The ability to manage all suppliers, online and offline, through one platform.
• Integration with your accounting or ERP stack: Clean data flow into tools like QuickBooks, NetSuite, and Sage Intacct.
• Indirect purchasing vs. raw materials: Be clear on whether the tool manages your indirect buying, or it's meant to source bulk raw materials. Most procurement platforms handle the former.

Score each tool against these criteria before you book a single demo. If you want to avoid looking for another new procurement tool in a year or two, be sure to weight them by where you're headed instead of just where you are today.

5 procurement software options for multi-location car washes

The five tools below take different approaches with a distinct best-fit profile. Pricing signals are included where available and should be confirmed directly with each vendor.

1. Order.co — Best for building scalable procurement processes

Order.co is a procurement and finance automation platform that centralizes purchasing across every location into one controlled, guided buying experience. It's built for multi-location operators who need spend control without slowing down site managers. Rather than leaving each site to source independently, Order.co gives every car wash a single place to order from approved catalogs, so consistency happens by default.

Benefits:

• Standardized, pre-approved product lists keep every site ordering the same SKUs.
• Customizable, multi-level approval workflows based on budgets, departments, or roles.
• All vendors, orders, and payments are managed in a single platform.
• Multi-entity management lets you configure separate branches or subsidiaries under one account.
• Finance gets line-item, real-time visibility over spend by location, team, vendor, and product category.

Considerations: Order.co is best at managing indirect purchasing. It doesn't support sourcing raw materials like chemicals. Though if a price and supplier are already set, it can support ordering for those products.

2. Precoro — Best for mobile purchasing

Precoro is a cloud procurement platform built around budget control. It lets finance teams manage spending across multiple cost centers, departments, projects, and locations from a single account. Purchase requests route through customizable approval workflows, and the platform tracks committed spend against budgets in real time so approvers can see the impact of a purchase before they sign off.

Benefits:

• Real-time budget tracking shows the impact of each purchase before approval.
• Multi-currency support for chains operating across borders.
• Integrations with ERP and accounting systems, plus a mobile app for approvals on the go.

Considerations: Pricing starts around $499 per month, and is billed annually for the Core plan, according to Vendr, which may be more than a smaller regional chain needs. Precoro is strongest for organizations that have outgrown spreadsheets but want to avoid a long ERP procurement rollout.

3. Ecotrak — Best for facility and asset management with purchasing built in

Ecotrak is a facility management platform designed for multi-location businesses. It covers work orders, asset lifecycle tracking, preventive maintenance, vendor management, and parts inventory from a single dashboard. Its purchase ordering module lets teams create, approve, and track orders for maintenance parts and services, tying procurement directly to the assets and facilities that need them.

Benefits:

• Asset lifecycle tracking monitors every cost on a specific piece of equipment from installation through replacement.
• Purchase ordering is tied to work orders and assets, so spend connects directly to what it maintains.
• Vendor management with real-time progress updates on service requests across all locations.
• Reporting and analytics give a centralized view of R&M spend, asset performance, and vendor activity.

Considerations: Ecotrak is a facilities-first platform. Its purchasing capabilities center on maintenance parts and services rather than the full range of indirect supplies a car wash orders, such as towels, office products, or cleaning consumables.

4. Fraxion — Best for expense management

Fraxion is a cloud-based procure-to-pay platform built for mid-size companies that need tight policy compliance and budget control across multiple locations. It covers the full cycle from purchase requisition through PO creation, invoice matching, and AP batching. Fraxion also includes expense management and travel request workflows, which makes it a broader operational spend tool rather than a purchasing-only platform.

Benefits:

• Full procure-to-pay workflow from requisition through invoice approval and AP batching.
• Mobile app for purchasing, expenses, budget reviews, approvals, and receiving from any location.
• Built-in expense management and travel request handling alongside procurement.

Considerations: Fraxion is built with procurement and finance professionals in mind. The depth of its compliance and policy controls is a strength for audit-heavy organizations, but evaluate whether that level of configuration matches what your site managers actually need day to day.

5. SAP Ariba — Best for large enterprises on SAP

SAP Ariba is an enterprise-grade procurement suite. It integrates natively with SAP ERP and S/4HANA, and supports connections to Oracle and other ERP systems through its Cloud Integration Gateway. For large organizations already running SAP, Ariba extends existing infrastructure rather than adding a standalone tool.

Benefits:

• Comprehensive sourcing, contract management, and supplier lifecycle management in one suite.
• Native integration with SAP ERP and S/4HANA, plus connectivity to Oracle and other systems.
• Bi-directional supplier data synchronization between Ariba and your ERP.

Considerations: SAP Ariba is designed for large enterprises with dedicated procurement teams and existing SAP infrastructure. Implementation is complex, timelines are long, and licensing costs reflect the enterprise scope. For most car wash chains, it is more platform than the operation requires.

How Spark Car Wash uses Order.co to scale

Whether a customer pulls in at a site in New Jersey or Pennsylvania, Spark Car Wash aims to deliver the same dependable wash. But with employees buying supplies from whichever vendors had stock, keeping those products consistent grew harder with every opening.

Spark implemented Order.co to establish standardized purchasing and gain control over spend before scaling further. Through the platform, the team can shop across all contracted suppliers in one compliant marketplace instead of jumping between different websites.

The results show up in three places:

• Purchases, approvals, order tracking, and payments now flow through automated, centralized workflows.
• General and district managers gained full visibility across the purchasing lifecycle.
• Custom approval workflows automatically route every purchase to the right manager for sign-off before it goes through.

"We love using Order.co because it sets a standard and makes it super easy for everyone to find what they need in the same place," said Kate Marinelli, Marketing Manager at Spark. "It creates a good continuity where everyone's gonna get the same customer experience no matter where they go when they visit a Spark."

Bringing order to car wash purchasing

For multi-location car wash operators, the customer experience is essential. A member who washes at three different sites in a month expects the same soap, towels, and finish every time. That level of consistency starts with what each location stocks, and what each location stocks depends on how purchasing is managed.

Standardizing procurement is what closes the gap between the experience you promise and the experience each site actually delivers. When every location orders from the same approved catalog, runs every purchase through the same approval process, and reports spend in real time, consistency stops being something you hope for and becomes something you can measure.

Order.co was built for exactly this kind of operation. Book a demo to see how it can bring structure to purchasing across all your car wash locations.
