Time-to-Invoice/Payroll CSV Exporter

The problem this kills

Every billing or payroll cycle, someone on your team becomes a human spreadsheet. They pull approved hours out of one system, look up the right bill rate or pay code for each person and project, round everything to the nearest quarter-hour (or whatever your contracts say), total it up, and then hand-retype or hand-paste the result into the exact column layout your invoicing or payroll tool demands. One transposed column or one fat-fingered rate and you've under-billed a client, overpaid an employee, or — worst of all — billed the same week twice.

It's slow, it's error-prone, and it's the kind of repetitive, rules-heavy work that quietly eats a whole afternoon every cycle. It's also exactly the kind of work software is good at — you just never had software for your rates, your rounding rules, and your import template.

What you'll build

A small, private web app that your finance and ops team logs into. You drop in this period's approved time (a CSV or a synced Google Sheet), and the tool automatically applies your rate and pay-code table, your rounding and minimum-increment rules, and produces a line-by-line preview of exactly what will be billed or paid. A finance owner reviews that preview, approves it, and only then does the tool generate a CSV in the precise columns your invoicing or payroll system imports — and stamps every entry as exported so the same hours can never sneak into a second batch.

What's inside the Implementation Plan

• It interviews you first. Before it builds anything, the plan has the AI agent ask you about your business — how you track time today, what your rate and pay-code table looks like, your rounding and minimum-increment rules, the exact column names your billing or payroll import expects, and your messiest edge cases. It reflects a short tailored spec back to you for a thumbs-up, then builds the tool around your answers instead of a generic template.
• A step-by-step build, where every step ends with a ready-to-paste prompt for your AI agent.
• A config-driven column mapping, so the export matches your system's import template exactly — and you can change it without touching code.
• The rate, rounding, and pay-code engine wired to the rules you describe in the interview.
• A finance review-and-approve screen with a full export preview.
• The "exported" stamp and duplicate guard that make double-billing impossible.
• A verification checklist and a CSV-export fallback path so the tool is fully usable today, even with no integration to your existing systems.

The governance it includes (this is the point)

This isn't a loose macro on someone's laptop — it's a controlled process:

• Login so only your team can open the tool.
• Row-level security so each organization only ever sees its own time, rates, and exports.
• A complete audit trail — who imported, who computed, who approved, and exactly when.
• A hard human-in-the-loop approval gate — the tool drafts the amounts, a finance owner reviews and approves, and only then is the file generated and the batch marked exported.
• A duplicate guard — entries are deduped on entry ID plus export batch, so the same hours can never be billed or paid twice.

Who it's for

Finance and billing coordinators, agency operations leads, and payroll administrators who own a recurring time-to-money cycle — and who are tired of being the manual bridge between a time-tracking sheet and a rigid import template.
