Sealed Ledger handles the work that doesn't fit into a monthly close — system migrations, deep data cleanup, and producing sealed, audit-ready archives that outlast the platforms they came from.
Moving accounting data between platforms is harder than it looks. Account types map differently. IDs don't survive. Inactive records get tangled up with active ones. Tax rates, classes, items, payment terms — every reference between records has to be remade in the new system, and the slightest mismatch quietly corrupts reports for years.
Our approach is different from a "lift and shift." We carry forward only what's needed to resume business as usual — open balances, current-year activity, master records that are still in use — and we seal the rest as a verifiable archive. The new file starts clean and reconciled. The history isn't lost; it's preserved in a form that's actually easier to reference than the original.
Most "messy books" aren't messy because of one big problem. They're messy because of small drifts that compounded over years — a duplicate vendor here, a miscoded transaction there, a reconciliation that was never quite finished. After a few treasurer turnovers or bookkeeper handoffs, the books stop telling the truth.
Cleanup work means finding the specific drifts, deciding which to repair and which to leave behind, and producing a file that ties back to source documents (bank statements, vendor invoices, prior-period closes) the way it should. We don't just close the gap — we explain how it got there, so it doesn't reopen.
An accounting file isn't useful forever. Software changes, subscriptions lapse, vendors get acquired, fiscal years close. But the data inside — the transaction history, the audit trail, the records you'd need if a question came up three years from now — that should outlast all of it.
Every Sealed Ledger engagement ends with a sealed snapshot: a complete, tamper-evident archive of the source-system data at the moment of the engagement. It's independently verifiable, doesn't depend on any vendor remaining in business, and stays usable as a reference long after the live file has moved on. You keep it. We don't.
Most accounting backups answer the question "what was in the file?" Sealed Ledger archives answer a stronger one: "what was in the file at this exact moment, and has anything changed since?"
Each archive is cryptographically signed at the moment of capture. Anyone with the archive — you, your CPA, an auditor, opposing counsel in a dispute — can independently verify that the contents haven't been altered since the seal was applied. No special software. No subscription required.
What the seal does not claim is also worth being clear about. The seal attests to what our tool extracted from the source system at a given timestamp. It doesn't independently verify the authenticity of the source-system data itself, and it can't — no software can. What it does, reliably, is freeze a moment in time. After the seal, nothing about the captured data can be edited without detection.
That's the most defensible thing an archive can claim. We don't claim more.
Every engagement starts the same way: a sealed read-only snapshot of your current accounting data. Nothing in your live file changes during this step. The snapshot is the foundation for everything that follows.
From the snapshot, we run a deep diagnostic — not a checklist, but an actual examination of the data: where balances tie out and where they don't, where duplicates exist, where the chart of accounts has drifted from how the books are actually being used, where reconciliations have quietly broken. The output is a written plan that describes what we found, what we recommend, what each option would cost, and what you'd have when we're done.
Only then does any actual work happen. Whether that's migrating to a new file, cleaning up the existing one, or producing an archive for a specific purpose, the work follows the plan and the plan is yours to approve, modify, or decline.
Engagements are scoped to specific outcomes, not retainers. We finish a project, deliver the result, hand over the sealed archive, and step out. We're not trying to become your bookkeeper.
Sealed Ledger is a service offering of Ubiquitous LLC, based in Connecticut and working remotely with clients nationwide. The practice is led by an engineer with a software background and several years of hands-on work with accounting data across QuickBooks Online, QuickBooks Desktop, and other systems. Sealed Ledger is a QuickBooks Online Certified ProAdvisor practice.
We're platform-agnostic by design. We work where your data lives, not where a vendor wants to sell. That's served us well across migrations into and out of QuickBooks, and lets us stay focused on the data problem rather than defending a particular product.
We're not a recurring bookkeeping firm. We don't close your month, run your payroll, or file your taxes. Those are different practices, often done well by people who specialize in them.
We're not industry specialists. If you need someone who knows the tax quirks of construction-industry job costing or the receivables conventions of medical billing, we're not the right firm. We're specialists in data, not in any particular industry's accounting.
And we're not generalists. We don't take engagements outside the three things we do well. If your situation isn't a migration, cleanup, or archiving project, we'll tell you so — and where appropriate, point you at someone better suited.
