# Stamp payroll

Irreversibly stamp payroll receipts. stamp_run queues every ready receipt of a run; send the ready count and net you checked with get_payroll, and a difference stamps nothing. restamp_row stamps a rejected receipt again after its employee was corrected. Receipts stamp in the background, each on its own; follow them with get_payroll. Safe retries require reusing the same idempotencyKey.

Tool: `stamp_payroll`

## Purpose

Irreversibly submit a run's ready receipts, or one corrected rejected receipt, for SAT stamping.

### Use when

The run's ready receipts were checked and the person confirmed their count and net.

### Do not use when

Receipts still need attention or are being calculated, or you need a one-off payroll CFDI; use create_payroll_invoice_draft.

- [`get_payroll`](/docs/en/mcp/tools/get_payroll.md) — **Read payroll**: Read payroll settings, runs (optionally of one frequency), one run with its receipt count and net per state, a run's receipts (optionally in one state), or one receipt with its lines and calculation.

- [`save_payroll`](/docs/en/mcp/tools/save_payroll.md) — **Save payroll**: Prepare or adjust payroll before stamping: change payroll settings (only the fields sent change; null clears one), prepare the run of a pay period (idempotent per period; receipts calculate in the background), change its payment date, recalculate it, or update one receipt (omit or include it, capture its amounts, or return it to the calculation), or prepare a canceled receipt again.

- [`get_document`](/docs/en/mcp/tools/get_document.md) — **Get document**: Retrieve one document by its public documentRef. Sales receipt details include stable lineRef values and remaining refundable amounts for sales receipt refunds.
