Explain a number.
Trace pay, tax, and deductions to the facts and cited rules that produced them.
Payroll can be easy to run and hard to doubt.
Modern payroll should be easy on payday and explainable long after it.
A worker asks why their check changed. A CPA needs the source of a tax number. A provider switch puts year-to-date balances at risk. An agency questions a period everyone thought was finished. Payroll becomes hardest when the answer is scattered across exports, tickets, screenshots, and overwritten records.
Runbook keeps an append-only record behind each approved payroll run: what was calculated, accrued, settled, filed, corrected, and preserved.
QUESTIONED RUN
Explainable
Employee asksWhy changed?
CPA asksWhich rule?
Agency asksWhat evidence?
Agent asksCan I verify?
Facts
Rules
Deltas
Seal
Three outcomes from one payroll record.
The record should make ordinary payroll easier and difficult payroll answerable.
Correct without erasing.
Keep the settled run intact and record the late fact, recomputation, and resulting delta.
Answer with evidence.
Connect payroll, liabilities, payments, filings, and corrections for a worker, CPA, or agency.
The signature workflow.
A questioned number becomes an explanation, a correction when needed, and a record another person can check.
Prepare
Runbook assembles workers, hours, taxes, deductions, employer cost, and liabilities.
Question
The operator opens an amount and sees its source facts, calculation, and rule snapshot.
Correct
If a fact arrived late, Runbook preserves the original and derives the exact change.
Verify
The approved run produces a sealed artifact a third party can check independently.
The winning product standard.
Make ordinary payroll as easy as the best modern systems. Make disputed payroll more exact, reconstructable, and independently checkable than a report or support ticket.
Easy when routine
Setup, inputs, review, approval, worker access, taxes, accounting, and support should feel like one service.
Exact when exceptional
Questions, notices, returns, corrections, and amendments should open the affected facts and obligations—not start a hunt through exports.
Automated with authority
Software and agents may prepare and explain work, but calculation, approval, external action, and outcome remain distinct and reviewable.
Provable afterward
The record should survive a provider switch, dispute, audit, correction, and system change without rewriting what was approved.
The claim we can defend today.
Runbook is not yet a full-service payroll provider. It is building toward that operational breadth on a record designed so every material number can be explained, corrected, and independently verified.
Payroll that shows its work.
See how a payroll record can explain a number, preserve a correction, and support an independent check.
