About This Automation

Retainer billing requires manual export of timesheets, comparison against client agreements, and reconciliation across multiple systems before invoices can be created. Manual steps introduce errors, delays, and repeated data entry that consume significant finance team capacity each month.

Automation compares logged hours against retainer caps, deduplicates entries from multiple sources, generates invoice line items, and sends invoices to clients on the same day. The finance team reviews only flagged discrepancies, freeing time for higher-value work.

Key features:

Compare timesheet hours against retainer agreements and flag overages automatically

Deduplicate and reconcile time entries logged in multiple systems

Calculate billable amounts and generate invoice line items without manual spreadsheet work

Send invoices to clients and log payment tracking details in one step

Route discrepancies to finance team for review before invoice creation
