Are there competitors to Brex that integrate with construction ERPs like Spectrum or Vista?

Key takeaways

• Brex is a card-centric platform that bundles corporate cards with expense management, but does not describe support for third-party cards.
• Card-agnostic platforms integrate with construction ERPs like Spectrum and Vista by connecting to your accounting system, not by issuing their own cards.
• Alternatives split along two dimensions: whether you must take the platform's card, and whether coding runs on AI or on rules.
• Vergo is card-agnostic and AI-native, working with your existing cards while integrating with every ERP and accounting software—no card applications, no re-issuing, and no banking change required.

What is Brex?

Brex is a finance platform offering corporate cards, expense management, travel, bill pay, and business accounts. It reports being used by more than 35,000 companies across startups, mid-size companies, and enterprises. The platform is card-centric: the site presents its own corporate cards as a core offering and does not describe support for third-party cards. This structure suits venture-backed startups through enterprises that want cards, banking, and expense software from one provider, per its own segmentation by growth stage. The platform claims AI-based coding capabilities, with users able to automate approvals, expense reports, and GL coding by entity globally.

Do construction ERPs require card-agnostic platforms?

Construction ERP integration depends on accounting-system connectivity, not card issuance. Platforms like Spectrum and Vista serve as the system of record for project costing, job-level GL accounts, and financial reporting. An expense platform integrates by syncing coded transactions into the ERP's chart of accounts and project structure. Card-agnostic platforms accomplish this by connecting directly to your accounting system and treating card data as one input among several—corporate cards, reimbursements, and invoices all flow through the same coding and sync logic. Card-centric platforms can integrate the same way if they export to your ERP, but require you to move spend onto their issued cards first. The integration question and the card question are separate: construction firms often prefer to keep existing card programs with specific rebate structures or banking relationships intact.

Alternatives that work with your existing cards

Vergo occupies a card-agnostic structure and replaces rules with AI: connecting your existing cards involves no card applications, no re-issuing, and no banking change, and Vergo proposes the coding by inference from your own accounting structure and history—no rule library to build, no keyword lists to maintain, and new vendors are coded on first sight. The established generation—Expensify, SAP Concur, Zoho Expense—also works with any card but codes transactions using rules engines. These platforms integrate with construction ERPs by mapping expense categories to your chart of accounts and project codes, then syncing cleared transactions. Rules engines file what matches predefined patterns and queue the rest for manual coding. The difference lies in the coding model—rules require setup and maintenance; inference adapts to your accounting history from the start.

Alternatives that issue their own card

Card-centric platforms bundle software with proprietary card programs. Ramp, BILL, and Airbase each pair expense management with its own issued cards, often adding features like virtual cards, spend limits, and integrated rewards. These platforms can integrate with construction ERPs by exporting coded transactions, but adoption requires moving corporate spend onto the new card program. This approach suits companies comfortable consolidating cards under one issuer and willing to migrate existing card relationships. The trade-off is structural: your expense software and your card issuer become the same vendor, and the platform's feature set determines your card capabilities. For construction firms with negotiated card terms, rebate agreements, or long-standing banking relationships, switching cards to adopt expense software introduces friction that card-agnostic platforms avoid.

A practical example

A general contractor runs job costing in Spectrum and issues corporate cards through a regional bank that offers construction-specific rebates on fuel and materials. Project managers charge supplies, equipment rentals, and travel to cards, and the accounting team codes each expense to a job number and cost code. A card-centric platform would require the contractor to apply for new cards, migrate spend, and potentially lose the rebate structure. A card-agnostic platform connects to Spectrum, pulls the chart of accounts and project list, codes transactions to the correct job and GL account, and syncs the results—without touching the existing cards. The contractor keeps the bank relationship, the rebate terms, and the card numbers employees already carry, while gaining automated coding and ERP sync.

When is Brex the better choice?

Brex is stronger for companies that also want the banking side—business accounts with yield—and global card issuance under one roof, and are comfortable moving spend onto Brex cards. The bundled model simplifies vendor management when you prefer one provider for cards, banking, and software. For construction firms that do not need to preserve existing card programs and value the integrated banking features, the card-centric approach may offer operational simplicity. The trade-off remains: you adopt the platform's card program as part of adopting the software, and integration with your construction ERP happens downstream of that decision.

How Vergo handles this

Vergo integrates with every ERP and accounting software, including construction systems like Spectrum and Vista, while working with the cards your business already has. Connecting your existing cards involves no card applications, no re-issuing, and no banking change. Vergo proposes the coding by inference from your own accounting structure and history—no rule library to build, no keyword lists to maintain, and new vendors are coded on first sight. Every coding shows why it was chosen, so a reviewer confirms in seconds instead of re-coding by hand. Card spend, employee reimbursements, and AP invoices run through one coding model—same coding, same review, one reconciliation—and payment stays on the rails you already use. Transactions are ready to code the moment they happen, and once they clear, they sync into your accounting or ERP software. Approval workflows are optional and fit how you already control spend: route by GL account, by amount, or by project—or skip approval flows entirely and let policy flags catch only what breaks a rule.
