What Airbase Actually Does
Airbase is often discussed in fintech circles, but it is important to describe it correctly. It is not really a bank, and it is not a climate-focused finance platform. Airbase is a spend management and finance operations platform built to help companies manage the money going out of the business.
That includes accounts payable automation, bill pay, expense management, corporate cards, and procurement workflows. In October 2024, Paylocity completed its acquisition of Airbase, describing the company as a modern finance and spend management solution that combines those core finance tools into one platform.
For climate companies, that distinction matters. If a founder is looking for a bank account, treasury product, climate lending partner, or project finance solution, Airbase is not the full answer. But if a climate startup needs better control over vendor payments, employee expenses, approvals, corporate card spend, and procurement, then Airbase can be worth evaluating.
Why Airbase Is Not the Same as a Climate Bank
The keyword “banking for climate companies” can be a little misleading when applied to Airbase.
A bank helps with deposits, cash management, lending, credit lines, treasury services, and sometimes financing. A climate bank or climate finance provider may also support green lending, carbon projects, renewable energy financing, or sustainability-linked financial products.
Airbase sits in a different part of the finance stack. It helps companies control and track spending after money is already available. It is closer to the daily operating layer of finance than the capital-raising or banking layer.
That does not make it less useful. It just means climate companies should know what job they are hiring it to do. Airbase can help organize spending. It does not replace a banking partner, a climate finance strategy, or tools for carbon accounting and impact reporting.
Why Climate Companies Have Different Finance Needs
A climate company often spends money differently from a pure software startup. A SaaS company may mostly deal with payroll, cloud costs, subscriptions, travel, and contractor invoices. A climate company may have all of that, plus hardware, field work, lab testing, pilot projects, grant tracking, manufacturing vendors, site visits, permitting, installation partners, and long procurement cycles.
That creates more pressure on the finance team.
A battery startup, carbon removal company, solar company, or grid technology company may need to approve expensive equipment purchases before revenue is predictable. A climate hardware startup may need to track spend by project, grant, location, or customer pilot. A renewable energy company may need better controls around vendor payments, compliance costs, and field-team expenses.
This is where a platform like Airbase can make sense. It gives finance teams a clearer way to approve, track, categorize, and report spending before it becomes messy.
Where Airbase Can Help Climate Startups
The biggest value of Airbase for climate companies is control.
Climate founders often begin with a small team, a few cards, a basic accounting system, and a lot of manual approvals. That can work early on. But once the company starts adding teams, vendors, field projects, and multiple budget owners, manual finance processes become risky.
Airbase can help by bringing several workflows into one system. Its current product positioning under Paylocity for Finance includes expense management, AP automation, corporate cards, guided procurement, and visibility across spend workflows.
For a growing climate company, that can mean fewer surprise expenses, cleaner approvals, better vendor records, and a faster month-end close. It can also help finance leaders understand where money is going before cash burn becomes a problem.
Corporate Cards, Expenses, and Vendor Payments
Climate companies can burn through cash quickly, especially when they are running pilots, buying equipment, or sending teams into the field. Without clear controls, spending can get scattered across personal reimbursements, card charges, invoices, and one-off vendor payments.
Airbase is useful because it connects corporate cards, expense management, and bill payments into a more structured workflow. Instead of letting every department handle spend differently, finance teams can create approval rules, assign budgets, review expenses, and sync data back to accounting systems.
This is especially useful for teams that deal with:
R&D spend
lab equipment
field equipment
software subscriptions
contractors
consultants
testing facilities
supplier payments
travel expenses
prototype costs
For climate companies, the issue is not only whether the spend is approved. It is whether the company can explain why that spend happened, which project it supported, and whether it fits the budget.
Procurement Controls for Climate Projects
Procurement is often underrated in climate startups.
A software startup may be able to move fast with lightweight purchasing rules. A climate company often has higher-cost purchases, longer vendor cycles, and more compliance concerns. Equipment, materials, engineering services, installation partners, and testing vendors can all create bigger financial commitments.
That makes guided procurement useful. A finance team can set up approval paths before a purchase happens, instead of chasing receipts after the money is already spent.
For example, a climate company may want different approval rules for a $300 software subscription, a $12,000 lab equipment purchase, and a $90,000 pilot-project vendor contract. Those should not be treated the same way.
Airbase can help make procurement more consistent. It gives finance teams a way to build approval workflows, track purchase requests, and keep spending aligned with company policies.
Grant Tracking, Audits, and Financial Visibility
Many climate companies rely on grants, non-dilutive funding, research programs, tax credits, or public-sector partnerships. That creates an extra layer of financial discipline.
If a company receives grant funding, it may need to show exactly how the money was used. That can require receipts, vendor records, approval histories, project-level categorization, and clean reporting.
This is where Airbase can be valuable, even though it is not a grant management platform. Its strength is in creating an audit trail around spend. That can help finance teams answer basic but important questions:
Who approved this purchase?
Which department requested it?
Which vendor was paid?
Was it tied to a project?
Did it match policy?
Was it coded correctly in accounting?
For climate startups that expect audits, investor diligence, or grant reviews, better spend visibility can save time and reduce stress.
What the SVB Crisis Revealed About Payment Rails
One reason to evaluate Airbase carefully is that fintech tools often depend on payment rails and banking partners behind the scenes.
During the Silicon Valley Bank crisis in 2023, TechCrunch reported that Airbase was processing more than $5 billion in annual payments on behalf of customers, with a large portion flowing through SVB from customer bank accounts. That moment showed how important payment-rail resilience can be for finance platforms.
For climate companies, this is a practical lesson. Many climate startups operate with limited runway, grant milestones, supplier deadlines, or payroll pressure. If vendor payments are delayed, the impact can be real.
That does not mean climate companies should avoid Airbase. It means they should ask smart questions before choosing any finance platform:
What banks or payment partners support the platform?
What happens if a payment rail is disrupted?
How quickly can payments resume?
Are there backup options?
How are customers notified during disruptions?
A finance platform is only as useful as its ability to keep money moving reliably.
Where Airbase Falls Short for Climate Finance
Airbase can help climate companies manage spend, but it does not solve every finance problem.
It is not built primarily for climate finance, carbon markets, green lending, project finance, climate risk assessment, or impact reporting. Those areas belong to a different part of the climate fintech ecosystem.
The IMF describes climate fintech as technology that can support climate finance, while also noting that fintech is only a partial solution and carries risks that need to be managed. The Green Fiscal Policy Network also frames climate fintech around areas such as digital banking and payments, investment and asset management, carbon markets and offsets, risk assessment, insurance, green crowdfunding, data provision, and compliance.
That is broader than what Airbase does. So the honest answer is this: Airbase can support the finance operations of a climate company, but it is not a complete climate finance solution.
How Airbase Fits Into a Climate Company’s Finance Stack
A climate company may need several tools working together.
It may use a bank for deposits and treasury. It may use an ERP or accounting system like NetSuite, Sage Intacct, or QuickBooks. It may use a payroll platform, a carbon accounting tool, a grant management system, and investor reporting software.
Airbase fits into the spend management layer. That means it can sit between employees, vendors, cards, invoices, procurement requests, and the accounting system.
A simple finance stack might look like this:
Banking partner for operating accounts and cash management
Airbase for spend management, cards, expenses, AP, and procurement
Accounting system for the general ledger and financial reporting
Climate reporting tool for emissions, impact, or sustainability data
Grant or project tracking system for restricted funding and milestone reporting
This is the right way to think about Airbase. It is not the whole stack. It is one important layer.
When Airbase Is a Good Fit
Airbase is likely a good fit for a climate company when the company has moved beyond informal spending.
It may be useful if the company has multiple teams requesting purchases, many vendors, frequent reimbursements, growing card spend, recurring software subscriptions, and a finance team that needs cleaner approvals.
It may also fit companies that are scaling from early-stage startup to growth-stage operations. Paylocity has described Airbase as focused on companies with roughly 100 to 5,000 employees, which gives a helpful sense of the customer profile it is built for.
A climate company should consider Airbase if it needs:
better spend controls
cleaner vendor payments
approval workflows
corporate card governance
expense policy enforcement
procurement visibility
faster close processes
real-time spend reporting
stronger audit trails
better connection between finance and operations
For a finance leader trying to bring order to fast growth, those benefits can be meaningful.
When Airbase May Not Be the Right Fit
Airbase may not be the right choice for every climate company.
If a company is very early, with only a few employees and simple spending needs, a lighter tool may be enough. If the main need is a business bank account, a treasury product, or climate project financing, Airbase is not the right starting point.
It may also fall short if the company needs deep climate-specific functionality, such as carbon accounting, ESG reporting, green loan management, carbon credit tracking, or project finance modeling.
Climate companies should also consider implementation effort. A platform like Airbase becomes more valuable when a company is ready to standardize processes. If the team does not have clear owners for approvals, policies, budget categories, and accounting workflows, the software alone will not fix the problem.
What Climate Companies Should Compare Before Choosing Airbase
Before choosing Airbase, climate companies should compare it with tools such as Ramp, Brex, Mercury, Bill.com, Tipalti, Spendesk, and Procurify.
The right comparison depends on the main need.
If the company wants business banking and treasury, compare Mercury or other banking platforms.
If the company wants corporate cards and simple expense controls, compare Ramp or Brex.
If the company wants AP automation and vendor payments, compare Bill.com or Tipalti.
If the company wants procurement workflows, compare Procurify or similar platforms.
If the company wants an all-in-one spend management system, Airbase becomes more relevant.
The best choice depends on company size, finance maturity, international needs, accounting setup, approval complexity, and whether the company is mostly software, hardware, project-based, or grant-funded.
Questions Climate Founders Should Ask
Before adopting Airbase, climate founders and finance leaders should ask:
Does this solve our biggest finance bottleneck?
Are we trying to fix banking, spend control, or climate reporting?
Which expenses need approval before purchase?
Do we need project-based or grant-based tracking?
Can it integrate with our accounting system?
How does it handle multi-entity or international spend?
What payment rails and banking partners support it?
How easy is it for employees to use?
Will it make month-end close faster?
Can it support audit and investor diligence?
These questions help avoid buying a tool just because it sounds like fintech. The goal is not to add software. The goal is to make financial operations cleaner, faster, and safer.
The Practical Verdict on Airbase for Climate Companies
Airbase can be a good fit for climate companies, but only if it is evaluated for the right job.
It is not a climate bank. It is not a full climate finance platform. It is not a carbon accounting system. It will not replace a banking partner, grant strategy, project finance model, or sustainability reporting tool.
But it can be a strong finance operations layer.
For climate companies dealing with vendors, hardware purchases, field expenses, contractors, grants, pilot projects, and growing teams, Airbase can help bring structure to spending. It can give the CFO, controller, and finance team better visibility into where money is going and why.
That matters because climate companies often have expensive, complex, and mission-critical spending. When the goal is to build cleaner energy, better infrastructure, carbon removal, sustainable materials, or climate software, financial discipline is not just back-office housekeeping. It helps the company survive long enough to make an impact.
So the best way to evaluate Airbase is simple: do not ask whether it is “banking for climate companies.” Ask whether it can help your climate company control spend, manage approvals, pay vendors, track expenses, and build the finance discipline needed to scale.
