How Streamside Parks closed a $97M acquisition on DualEntry without missing a beat

Mark Paul has implemented enough ERP systems in 36 years to dread the next one. He runs finance at Streamside Parks, an RV resort roll-up that has grown from a single park in 2023 to 36 properties across more than 50 legal entities, coast to coast.

The Problem

30 silos, one Excel file, and a close that never ended

Streamside ran 30 separate instances of QuickBooks Online. One per park. Thirty silos that didn't talk to each other.

Any consolidated view meant exporting everything into Excel and stitching it together by hand. A balance sheet roll-up was a project, not a click. Third-party bookkeepers absorbed the transaction volume, and the close still dragged past a month. By the time senior leadership saw a financial package, the numbers were stale and the window to act on them had passed.

For a company acquiring parks across the country, that broke the business. You cannot pivot on month-old data when you are doubling in size.

The Solution

One ERP, 50+ entities, a few clicks

Alex Brahm, Streamside's Senior Director of Finance, selected DualEntry before Mark joined. Brahm had lived through several NetSuite implementations at other companies. Overruns. Data that would not migrate. Timelines that dragged on and on.

When Mark arrived in October 2025, he had the opportunity to veto the call. He ran his own due diligence, went back to NetSuite, revisited Yardi, both platforms he already knew. Ultimately he stuck with DualEntry.

DualEntry put all 50+ entities on one platform:

• Consolidated financials across every entity in a few clicks, no Excel roll-up
• A daily API integration with the Camp Spot point-of-sale system, replacing manual flat-file downloads and uploads
• Ramp credit card transactions flowing in automatically every day
• Native AI running bank reconciliations, journal entries, and accruals
• Dozens of hours a month handed back to the team for analysis

Then came the real test. On February 1, 2026, Streamside moved every location onto DualEntry. That same month it closed a $97 million acquisition of seven parks, more than doubling its top line. Those seven parks never touched QuickBooks. They went straight onto DualEntry, and the migration team stood them up fast. Streamside, in Mark's words, “didn't miss a beat.”

Results

• Financial package: built by hand after the period closed, now ready within about two and a half calendar weeks, in time to actually change course
• Consolidation: Excel marathons, now a few clicks
• Systems: 30 QuickBooks silos, now one ERP across 50+ entities
• Capacity: dozens of hours a month freed for analysis

Six people now run finance across the country on DualEntry. 

Mark has spent 36 years in accounting, including controller and CFO seats at multiple Fortune 500 and public companies, and run enough ERP rollouts to know they drag on for months. This one didn't: "Moving to DualEntry has allowed us to close the books in ten days. It's been a monumental game changer for us in our ability to get financial reporting out to the Chief Operating Officer and the operations team so that we can pivot and make changes as necessary."
