Cost Report Template Generator for MarkiTect.
|
|
|
|
This module generates professional markdown cost reports from database data
|
|
with proper frontmatter/contentmatter structure. Reports include cost breakdowns,
|
|
issue allocations, and audit trails.
|
|
|
|
Supports multiple formats:
|
|
- Summary: High-level overview with totals
|
|
- Detailed: Complete breakdown by category and item
|
|
- Audit: Full transaction history and audit trail
