### Reconcile Transactions

Reconcile the transactions processed with [Customer Portal Explorer](https://communications.avalara.net/AFC/Reporting/Explorer) after your application comes back online. Temporary transactions such as uncommited tax estimates do not need to be reconciled.

### Duplicate Transactions

Review all transactions processed during the time of the outage to confirm that a transaction is only accounted for once. The transactions and related tax data can be reconciled by reviewing reports and tax data using the [Customer Portal Data Explorer](https://communications.avalara.net/AFC/Reporting/Explorer).

When a transaction is included more times than expected:

-   Use the [Commit endpoint](/communications/dev-guide_rest_v2/commit-uncommit/commit-request/) to uncommit the duplicate Document Code (`doc`) and commit only the final Document Code
-   Reprocess duplicate transactions using a new unique Document Code (`doc`) and [commit](/communications/dev-guide_rest_v2/commit-uncommit/commit-request/) this final Document Code
-   Run [adjustment transactions](/communications/dev-guide_rest_v2/customizing-transactions/sample-transactions/adjustment/) (`adj` = `true`) to negate the duplicate amounts
