From Sub Docs to General Ledger: Our Latest Integration with Ark

The investor onboarding process doesn't end when someone signs a subscription document. That's really where your fund operations begin—capital calls, distributions, LP reporting, and all the accounting work that happens throughout a fund's lifecycle.

We're announcing our integration with Ark that creates automatic data flow from executed sub docs in Passthrough directly into Ark's back office and investor relations solutions. This connection eliminates the manual work that typically sits between fundraising and ongoing investor management.

Where Fund Workflows Break Down

Most firms experience a significant operational break between closing a fund and beginning fund operations. Investors complete and sign sub docs. Legal reviews and executes them. Then someone—usually finance staff or a fund administrator—manually extracts data from those PDFs and enters it into the general ledger.

This manual transcription process creates multiple problems. It's slow, taking anywhere from 6-10 hours for a 50-investor fund to multiple days for larger raises. It's error-prone, with typos in entity names, transposed digits in capital commitments, and incorrectly formatted payment details creating reconciliation issues that persist throughout the fund lifecycle. And it's completely unnecessary work that adds no value but delays your ability to issue capital calls and begin operations.

The data your finance team needs already exists in structured format from Passthrough. It just needs to flow automatically into Ark instead of requiring manual rekeying.

Connecting the Workflow: How It Works

Our integration with Ark creates a direct data pipeline from investor onboarding to fund accounting:

Step 1: Investors complete sub docs in Passthrough. Your customized workflows collect all the information your fund needs—capital commitments, entity structures, tax details, payment instructions, and contact info.

Step 2: Documents get reviewed and executed. Your legal counsel reviews responses, requests revisions if needed, and marks documents as fully executed once the fund closes.

Step 3: Data automatically flows to Ark. Passthrough generates structured data formatted specifically for Ark's platform. Ark ingests this and maps investor information directly to LP records in your investor portal and general ledger.

Step 4: You're ready for operations. Your finance team or fund admin can immediately issue capital calls, generate LP reports, and manage ongoing fund operations with accurate investor data already in Ark.

No manual transcription. No delays between close and operations.

Why This Matters for Different Stakeholders

For fund managers: Your finance and IR teams stop wasting time on data entry and can focus on actual fund operations. You reduce errors that create reconciliation problems. And you accelerate time from fund close to first capital call.

For fund administrators: You eliminate the single biggest operational bottleneck when onboarding new GP clients. Clean data flows automatically from your clients' fundraising activities into your fund accounting workflows. You can offer premium investor onboarding services to clients while maintaining your existing operational processes in Ark.

For finance teams: You get structured, validated data instead of manually extracting information from PDFs. Capital commitments, entity details, and payment instructions are already formatted correctly for your general ledger. You spend less time fixing data errors and more time on financial analysis and reporting.

Best-of-Breed Tools, Connected Workflows

This integration reflects how both Passthrough and Ark approach fund technology: we build tools that work together, not against each other. Neither platform is trying to replace your entire tech stack. We're building the most effective investor onboarding and financial crime compliance solution in the market, then systematically connecting it to the specialized tools fund managers already use.

Ark excels at fund accounting, LP reporting, and administration because that's what they built their platform to do. Passthrough excels at investor onboarding and financial crime compliance because that's all we do. When specialized tools connect seamlessly, fund managers get best-in-class capabilities across their entire workflow without compromising on quality or forcing standardization that doesn't fit their operations.

Over the past year, we've launched integrations for document compliance management, investor portals, and LP relationship management. Ark strengthens our ecosystem with deep fund accounting and LP reporting capabilities. Each integration eliminates manual work at different points in fund workflows, and together they create end-to-end automation from first LP contact through ongoing fund operations.

Built Because You Asked

Fund managers and admin using both Passthrough and Ark requested this integration specifically. They told us Ark handles their fund accounting and LP reporting exceptionally well, and now automatic data flow from sub docs makes their operations even more efficient.

We're actively developing additional integrations based on these conversations. If there's a tool in your fund tech stack that should connect with Passthrough, we want to hear about it. Fund workflows shouldn't break down just because data needs to move between systems.

Getting Started

The Passthrough-Ark integration is available now. If you're using Ark for fund accounting and want to eliminate manual data entry from your LP onboarding workflow, reach out to learn about implementation.
