How Guesty saves property managers hundreds of hours managing expenses

Guesty is the leading AI property management platform for the short-term and vacation rental industry. Known as the "host of the hosts," Guesty provides property managers with an all-in-one solution to run every aspect of their business. Operating in over 100 countries, Guesty continues to expand its North American footprint through major strategic partnerships, powering operations for a rapidly growing franchise network of more than 40,000 vacation rentals.

As the leading platform for professional property managers, Guesty serves as the operating system for thousands of hospitality brands worldwide. These companies, ranging from boutique vacation rental hosts to enterprise giants, juggle a high volume of daily operational costs — emergency plumbing repairs, cleaning supplies, landscaping, and vendor bills.

Managing these expenses created a heavy administrative burden. Field teams routinely shared physical cards or paid out of pocket, forcing property management companies to front their own capital for owner-related expenses. Floating cash across thousands of listings tied up vital working capital and strained operational budgets while teams waited weeks for end-of-month reconciliations to recoup those funds from owners.

The challenge was even more acute due to the complexities of trust accounting. In property management, every dollar spent on a specific property needs to be accurately mapped to each property's ledger, resulting in timely and accurate monthly owner statements. For enterprise-level networks, fronting these expenses at scale eats into operational liquidity and directly impacts profit margins. Standard commercial cards simply weren't built to handle this operational scale, offering no way to automate payments directly from each property's dedicated external account.

Guesty knew that solving this time-consuming, margin-eroding bottleneck would be a game-changer for their customers. But building a native financial product from the ground up meant navigating a minefield of complexities:

1. 1

   The massive overhead of risk, compliance, and underwriting: Building a secure commercial card program requires far more than a sponsoring bank. Developing specialized underwriting models, navigating strict compliance, and managing fraud and risk requires years of upfront work and a continuous commitment to staff a dedicated operations team.

2. 2

   Engineering opportunity cost: Diverting elite engineering talent to build intricate ledger infrastructure, transaction-routing logic, and card tokenization protocols would have severely stalled product velocity. Every engineer building financial backend systems is an engineer not pushing forward Guesty's right to win.

3. 3

   Balance sheet and capital risk: Launching a credit product requires securing, scaling, and managing a massive credit facility. Without a partner, Guesty would have had to absorb direct credit risk and hold significant capital on their balance sheet.

Using CapitalOS's infrastructure, the team launched the Guesty Card, a fully embedded spend management program. To go one step further, Guesty leveraged CapitalOS APIs and data to route all card spend directly into its advanced accounting ledger, automating receipt collection, memo capture, and approval workflows.

The result? Hundreds of hours saved monthly and a complete elimination of the end-of-month rush to close the books. These gains extend across Guesty's customer base, from managers handling monthly expenses of around $5k to enterprise portfolios with over $1M in operational spend.

Linking the Guesty Card to their proprietary Guesty Accounting engine transformed a commodity credit card into a powerful operational tool. This integration streamlined the most complex parts of the property management workflow through three core capabilities:

1. 1

   Property-level ledgers: Every transaction is automatically tagged to one or more specific properties. Whether a cleaner buys supplies or a contractor handles an emergency repair, the expense is instantly routed to the correct property ledger.

2. 2

   Receipt capture and documentation: Mobile notifications prompt employees to capture and submit receipts and memos at the time of purchase. These digital records flow seamlessly into the Guesty platform, giving owners 100% transparency into how their funds are spent while enabling managers to track every purchase in real time.

3. 3

   Revenue-based underwriting: CapitalOS's underwriting agents use real-time business performance data from the Guesty platform to provide higher, more accurate credit limits that reflect a manager's true cash flow.

The partnership also offers white-glove support — from complex reconciliation logic to expedited card deployments — for Guesty's largest enterprise accounts. Throughout the implementation, CapitalOS acted as a strategic launch partner, providing expert integration support to ensure a seamless deployment.

By partnering with CapitalOS, Guesty transformed property-level expense management from a manual burden into an automated growth engine. Today, the Guesty Card provides property managers with the financial autonomy they need to run high-volume operations without the traditional friction of bank underwriting or manual reconciliation.

The impact is reflected in the platform's high adoption and engagement metrics:
