How using this software benefits accounting and tax workflows

Common implementation challenges

  • Reconciling solar incentives and tax credits with client accounting records can create version-control issues across teams and documents.
  • Ensuring secure transfer of sensitive tax data when sending proposals increases administrative burden without proper encryption and access controls.
  • Mapping custom depreciation schedules and incentive calculations into templated proposals requires time-consuming setup and ongoing maintenance.
  • Coordinating signatures across multiple signers, tax preparers, and third-party finance partners often creates delays and tracking gaps.

Best practices for secure, accurate proposals and signed tax documents

Follow these practices to reduce errors, improve security, and ensure signed documents meet accounting and tax audit requirements.

Use standardized, reviewed templates across the firm
Maintain centrally approved templates that include required tax disclosures, calculation fields, and consistent formatting. Periodically review templates for regulatory changes, and version-control templates so reviewers can trace edits and reapprove updated content before use.
Require appropriate authentication levels for signers
Apply stronger authentication for signers of tax-sensitive documents, such as multi-factor authentication or identity verification. Align authentication methods with the document’s risk profile and retain evidence of the authentication process in audit logs for compliance reviews.
Integrate with accounting systems to reduce manual entry
Map proposal fields to accounting records and tax schedules to avoid duplicate data entry. Automated integration reduces transcription errors, ensures consistent dollar amounts, and speeds reconciliation between proposals and ledger entries.
Document retention and archival policies
Define retention schedules by document type and tax year, implement secure archival procedures, and routinely verify backups. Ensure retention policies meet statutory requirements and that archived documents remain retrievable for audits.
