Benefit Deduction Change Manager

The problem this kills

Open enrollment ends and the changes pour in from everywhere: a benefits inbox, a stack of life-event forms, a spreadsheet someone keeps in a shared drive, a few Slack messages. Then payroll has to turn all of it into deduction changes with the right effective dates before the next run, by hand.

That is where it goes wrong. A 401(k) election sails past the annual contribution cap. A medical change gets the wrong effective date and back-bills three pay periods. A qualifying life event lands outside its eligibility window but nobody catches it. The same change gets keyed twice because it came in on two forms. Every one of these surfaces as an angry employee, a correction, and an off-cycle adjustment after the run.

The real problem is that nothing validates the elections before they hit payroll, and nothing forces a person to sign off on each one. This tool puts a checkpoint between "employee elected a change" and "payroll imports it."

What you'll build

A small, secure web app your HR/benefits and payroll team logs into. People submit (or paste in) deduction-change elections - new enrollments, mid-year qualifying life events, and contribution-percentage changes. The tool checks each change against your plan rules and limits, flags the problems, and queues the clean ones for an approver. The approver reviews each change one at a time, approves or rejects it with a reason, and only approved changes get batched. When the batch is ready, the tool exports a deduction-change import CSV in your payroll provider's exact column layout, plus a human-readable change summary.

It keeps a per-employee deduction history, so you can always see what changed, when it took effect, and who approved it.

What's inside the Implementation Plan

The plan opens by interviewing you about your business - your enrollment process, the systems and spreadsheets you use today, your real deduction codes and effective-date rules, your contribution limits, your typical and peak volumes, and your messy edge cases. It reads a short tailored spec back to you and waits for your thumbs-up. So you get a tool shaped to your plans and your payroll provider, not a generic template you have to bend to fit.

From there it walks you, prompt by prompt, through:

• Standing up the app, the login, and the database with row-level security.
• A data model for elections, plan rules, contribution limits, and per-employee deduction history - shaped by your interview answers.
• The validation engine: contribution-limit checks (like the 401(k) annual cap), effective-date rules, and life-event eligibility windows.
• Duplicate guards so the same change can't be batched twice.
• The approval queue and the human review screen.
• The approved-batch export to your payroll provider's import columns, plus the change summary.
• A "No API yet?" fallback that imports your changes from a Google Sheet or CSV and exports the deduction-change file in your provider's exact columns - so it is fully usable today.

Each step ends with a ready-to-copy prompt you paste into your AI agent.

The governance it includes (this is the point)

This is not a spreadsheet macro. It is built like the compliance tool payroll actually needs:

• Login so only your team can use it.
• Row-level security so people only ever see their own organization's data.
• A human-in-the-loop approval gate - the tool validates and drafts the change, a person reviews each one and approves it, and only then is it allowed into the payroll batch.
• A complete audit trail - who submitted, who approved or rejected, what the values were, and when, with a per-employee deduction history.
• Duplicate guards so the same election can't be processed twice.

Who it's for

HR/benefits and payroll teams who run open enrollment and handle mid-year benefit changes, and who are tired of turning a flood of elections into a payroll import by hand and praying the next run is clean.

You've got this - paste the first prompt and let the plan interview you.
