How Quanta works

We're an accounting operation that grows with your finance team

Experts own your books

Quanta runs your close, reconciliations, accruals, revenue recognition, financial statements, and audit preparation. Your team reviews the decisions that matter.

Close, fully managed

Revenue treatment, accruals, allocations, and exceptions are reviewed by accountants who understand your business.

Judgement where it matters

Revenue recognition, accruals, allocations, and material estimates are reviewed by accountants who understand the policy.

A team that knows your books

SF-based named accountants own the work, understand your recurring edge cases, and surface issues before they delay the close.

We build what your accounting requires

When standard software breaks, Quanta connects your systems and builds the reconciliations, subledgers, and workflows your accounting requires.

Your systems, connected

Bring together the operational and internal data required to account for how your business actually works.

No more monthly workarounds

Turn recurring spreadsheets, manual calculations, and one-off processes into managed, repeatable accounting.

Every balance supported

Custom reconciliations keep source activity, supporting schedules, and ledger balances aligned.

Have a non-standard system or manual workflow?

We can scope additional integrations and accounting support around it.

Every number keeps the work behind it

Quanta’s modern general ledger holds more than the final entry. Operational data, accounting logic, reconciliations, workpapers, and review stay connected in one living record.

Trace any number to its source

Move from any reported balance to the entries, supporting schedules, calculations, and source activity behind it.

The reasoning stays attached

Adjustments, approvals, and material judgments stay connected to the records and balances they affect.

Prepared throughout the month

Source data and reconciliations stay current, so Finance can see what is complete and what still needs review.

Connect your agents to the books

Use MCP to give approved agents access to trusted financial data and the context behind every number.
