How Flying Ledger Onboarding Connects Your Source Systems

Flying Ledger’s guided onboarding connects your source systems, maps your accounts, customers and vendors, and identifies your entity structure. That means the setup work — the part where most financial tools stall — is walked through step by step so the platform starts with a clean, correct picture of your books before it does anything else.

What does guided onboarding actually do?

Guided onboarding connects your source systems, maps accounts, customers and vendors, and identifies your entity structure. In practice, that’s three jobs: hooking up the systems your data already lives in, matching the records inside them so the same customer or vendor isn’t counted twice, and figuring out how your legal entities relate to each other.

Flying Ledger connects QuickBooks, Toast (restaurant POS) and Tripleseat (event booking) per entity and keeps that data synced automatically. Onboarding is where those connections get made and verified, so the automatic sync afterward is working from a foundation you’ve reviewed.

Why does mapping accounts, customers and vendors matter?

Mapping is the process of telling the platform which records across systems refer to the same real-world thing. Without it, one vendor entered three different ways in QuickBooks looks like three vendors, and revenue from a POS system doesn’t line up with the accounts it should post to.

Getting this right during onboarding is what makes the rest of the platform trustworthy. Once vendors are mapped, Flying Ledger can clean up messy vendor names and show every open bill across entities by who it’s really owed to. Once accounts and event categories are mapped, revenue recognition can break event data down by category and post the correct deferred-revenue and revenue journal entries into QuickBooks. The mapping you do once feeds every report and reconciliation after it.

Why does identifying entity structure come first?

Identifying your entity structure means telling the platform which companies you run and how they relate — parent to subsidiary, and which systems belong to which entity. Flying Ledger works for any business on QuickBooks, but businesses running multiple entities get the most benefit, and that benefit depends on the platform knowing the shape of the portfolio.

That structure is what makes cross-entity features possible. The CFO Dashboard shows cash, debt, revenue, net income and accounts payable across every entity in a portfolio. Intercompany reconciliation confirms what one entity owes another matches on both sides of the books. Cost allocations can allocate from a parent company to subsidiaries. None of that works until onboarding has established which entities exist and how they connect.

What happens after onboarding?

After onboarding, Flying Ledger keeps your connected data synced automatically and the platform’s features run on your live numbers. Daily point-of-sale revenue gets reconciled against what the POS system itself reports, Treasury shows real bank and credit-card balances with a health score, and “Ask Fly” answers financial questions using the platform’s own live numbers rather than a guess.

Because onboarding already mapped and structured everything, these features start with data that reflects your actual books instead of a rough approximation you’d spend weeks correcting.

Who is this for right now?

Flying Ledger is actively used internally with real customer data today; it is not yet open to external users or a public beta. Guided onboarding is the on-ramp for when access opens — the process designed to get a new organization from raw QuickBooks, Toast and Tripleseat connections to a clean, mapped, entity-aware setup that the rest of the platform can build on.
