How Waymo built IPO-ready lease accounting after a failed platform migration

Waymo does not do anything small. The Alphabet subsidiary operates one of the most ambitious autonomous vehicle programs in the world, with testing facilities, operations centers, and office spaces spread across multiple states. When conversations about a potential public offering started getting serious, the finance team realized that lease accounting was a gap they could not afford to leave open.

Lisa Martinez, Waymo's Controller, had already been through one failed platform migration. The previous tool had been selected for its AI capabilities, but the reality did not match the sales pitch.

"The AI within the previous tool was making errors we could not explain," Martinez says. "Timezone support did not work properly for our West Coast operations. The integration with our ERP was incomplete. We spent four months trying to make it work and ultimately had to walk away."

Starting over with higher stakes

The failed migration cost Waymo both time and credibility internally. Martinez needed to justify another platform investment to an executive team that had already seen one attempt fail. The IPO preparation timeline made the urgency real: the company needed SOX-compliant lease accounting before the next audit cycle, not after.

Waymo's portfolio included roughly 150 leases, but the complexity was disproportionate to the count. Testing facilities had unusual terms, including variable rent tied to usage metrics. Some agreements blended real estate and equipment components. Several leases contained embedded options that required careful judgment about whether to include in the liability calculation.

"We had leases that required real accounting judgment," Martinez says. "Not just plug-and-play calculations. And after the previous experience, I needed a platform that could handle the nuance without inventing answers."

The existing process also lacked the controls that SOX compliance demands. There was no formal review workflow, no segregation of duties, and no systematic way to track who changed what and when. Everything was managed in Excel, with lease files stored on a shared drive. No audit trail, no version control.

Why Arvexi won after another tool failed

Martinez's evaluation criteria were shaped by the previous failure. She required every vendor to model five complex leases from Waymo's actual portfolio - including a variable-rent testing facility and a blended real estate and equipment agreement. She also required a live demonstration of the audit trail and control framework, not just screenshots.

"We gave every vendor the same five leases," Martinez says. "Arvexi was the only one that got all five right without manual overrides. The other platforms either could not handle the variable components or required workarounds that defeated the purpose of automation."

Arvexi's audit trail and role-based controls were built into the core architecture rather than added as an afterthought. Every data point traces to a source document. Every change is logged with a timestamp and user ID. Review workflows enforce segregation of duties with configurable approval chains.

Implementation took eight weeks. Arvexi's team worked alongside Waymo's external auditors during setup to ensure the configuration met SOX requirements from day one. "Having the auditors involved during implementation was a turning point," Martinez says. "They signed off on the controls before we went live, not after."

The daily difference

The monthly close dropped from 11 days to 4. More importantly, every close now produces a complete audit package automatically - roll-forward schedules, disclosure reports, and supporting documentation that the auditors can pull directly from the platform.

The Document Intelligence module handles new lease ingestion as Waymo expands into new markets. When the real estate team signs a new facility agreement, the document is uploaded, parsed, and routed for accounting review. Martinez's team validates the extracted terms, applies the necessary judgment calls, and approves the setup. The entire process takes hours instead of the days it previously required.

"Before we sign a letter of intent on a new facility, I can tell the real estate team exactly what the accounting treatment will look like," Martinez says. "That changes the negotiation dynamic."

Ready for scrutiny

In the 12 months since implementation, Waymo achieved full SOX compliance for its lease accounting function. The external auditors completed their first review of the new process with zero findings.

"The auditors spent half the time they budgeted," Martinez says. "They said they had never seen lease accounting documentation this clean at a pre-IPO company. After the previous platform failure, that was deeply satisfying to hear."

The portfolio has grown to over 170 agreements as Waymo expands its operations footprint. Each new lease flows through the same controlled process, maintaining the audit standard regardless of growth.

"We built something that scales," Martinez says. "Whether we are at 150 leases or 500, the process is identical. The controls are identical. The audit trail is identical. That is what public market readiness actually looks like - and it is what the previous tool could never deliver."
