Digital Asset Reconciliation For Finance Teams
Rebuild balances from source activity, review inventory over time, and prepare cleaner outputs for your ERP.
A clearer view of digital asset activity before it reaches the books
BlockBriar collects wallet, custody, and exchange activity, rebuilds balances and inventory over time, identifies transfers between company-controlled accounts, and prepares outputs finance can review before posting to the ERP.
Digital asset close creates problems general ledgers do not solve on their own
Finance teams often have the data, but not a reliable way to turn it into a clean period-end answer across wallets, custody systems, spreadsheets, and accounting workflows.
What teams are dealing with
- Wallet history and custody exports
- Spreadsheets and manual adjustments
- Transfers between company accounts
- Balances that do not tie out cleanly
What that creates
- Longer close cycles
- Low confidence in period-end balances
- Inventory questions that are hard to explain
- More manual review before posting entries
Why this happens
- 1. Digital asset activity carries ownership, location, and transfer details that are hard to manage in spreadsheets alone.
- 2. ERP workflows still need a reviewed answer for balances, inventory, and exceptions before entries are posted.
- 3. Different source systems often describe the same activity in different ways.
- 4. A team may already have tools in place and still need a cleaner reconciliation process.
What BlockBriar helps teams do
The service is designed to turn source activity into a ledger finance can trace, review, and use for close support.
Core capabilities
The workflow centers on reconstruction, inventory support, reconciliation, and ERP handoff.
Rebuild balances from source activity
Review balances based on underlying transactions instead of relying only on exported balance summaries.
- Wallet and custody ingestion
- Unified ledger structure
- Deterministic replay
- Point-in-time balances
Support inventory and cost basis review
Track inventory by wallet, vault, ownership group, and reporting period with lot-based behavior and valuation support.
- Lot creation and consumption
- FIFO-based support
- Historical valuation inputs
- Carrying value rollforward
Review exceptions before close
Surface unresolved transfers, missing ownership mappings, valuation gaps, and ambiguous activity so finance can review open items before posting.
- Transfer identification
- Exception reporting
- Review queues
- Optional ERP sync
How the workflow is designed
Built for traceability and review
The workflow is built around source activity, replayable results, and clear review paths when the underlying data is incomplete or ambiguous.
Source-based ledger
Transactions and signed ledger entries are used to rebuild balances and support traceability.
Cross-system reconciliation
Custody data, wallet activity, and accounting records can be compared in one workflow.
Inventory-aware outputs
Reports are built to support inventory, lot activity, and period-end positions.
Review where needed
Open items remain visible instead of being forced into an overconfident classification.
Data cleanup controls
Spam assets, duplicate mappings, and import issues can be managed so the ledger stays usable.
Scoped deployment
Teams can begin with one entity, one wallet group, one custody environment, or one reporting period.
What the service can cover
- Wallet and custody ingestion across supported addresses, custody systems, CSV imports, and selected exports
- A unified ledger structure with asset, location, transaction, signed ledger entry, ownership grouping, and trace metadata
- Point-in-time balances by wallet, vault, ownership group, asset, and reporting cutoff
- Transfer identification so company-controlled movement does not distort gains, expenses, or acquisitions
- Lot-based inventory and FIFO support
- Historical valuation inputs with transaction-day and reporting-date pricing support
- Exception reporting for missing mappings, unresolved transfers, unmatched flows, and valuation gaps
- Month-end workflow support and optional ERP sync
Coverage depends on the reporting scope
- Supported sources and workflows are defined during scoping.
- Teams usually start with spot asset balances, reconciliation, and inventory support.
- A limited reporting perimeter is often the fastest way to get a useful result.
- Additional workflows can be assessed after the initial scope is clear.
The service works best when the reporting perimeter, data sources, and outputs are defined up front.
How It Works
A workflow finance teams can review
The service follows a repeatable sequence from data collection through reconciliation and output preparation.
Define the reporting scope
Set the entity, wallets, custody accounts, ownership mappings, reporting period, and assets to review.
Collect source activity
Bring in on-chain history, custody history, account exports, and supporting metadata.
Build the ledger view
Organize activity into transactions, signed ledger entries, ownership groupings, and trace data.
Rebuild balances and inventory
Compute historical balances, point-in-time positions, lot activity, and transfer treatment.
Review exceptions
Flag missing owned addresses, unlabeled activity, unmatched transfers, provider differences, and valuation gaps.
Prepare outputs
Deliver reconciliation reports, inventory rollforwards, supporting schedules, review queues, and optional ERP-ready journals.
Operational Outputs
- Wallet and vault inventory by asset
- Point-in-time balances
- Movement history by ownership group
- Unresolved transaction queue
Finance Outputs
- Inventory lot schedules
- FIFO support
- Period-end valuation support
- Reconciliation tie-outs
Control Outputs
- Source-to-ledger traceability
- Exception reporting
- Deterministic replay
- Comparisons against source systems
Teams that usually benefit first
The service is usually most useful for teams that already hold digital assets and need a more reliable close process.
- Crypto-native operators holding spot assets
- Fintechs using stablecoins operationally
- Treasury teams with wallets and custody in place
- Controllers and finance teams preparing for audit or close
- Teams using Fireblocks or similar custody systems
- Companies that want a second view alongside an existing ledger or vendor
Why teams start here
- It addresses a defined reporting problem without changing the whole finance stack.
- It can be tested on one entity or one reporting period.
- It focuses on balances, inventory, and open issues that matter at close.
Common concerns finance teams bring in
These are typical issues teams want to resolve before period-end numbers are posted.
Controller
Period-end review
We need to support the balance with source activity, not just accept an exported number.
Treasury lead
Inventory visibility
We need one view of what we hold across wallets, custody accounts, and reporting periods.
Finance operations
Reconciliation support
We need transfers, exceptions, and open items separated clearly before entries are posted.
Frequently asked questions
Common questions about scope, ERP handoff, custody support, and reconciliation workflows.
Start with a defined reporting scope
If digital asset balances are already part of your close process, a pilot can focus on one reporting perimeter and produce a concrete set of outputs for review.
What did we hold, where was it held, and what should reach the books?
Typical pilot scope
- One legal entity
- One custody environment or wallet group
- Selected spot assets
- One reporting period
- One ERP output target
