AP Handoff Packet Builder: One Clean, Auditable Bundle Per Invoice

The problem this kills

The invoice is approved to pay. Now comes the part everyone hates: getting it cleanly to Accounts Payable. The PO is in one email thread, the receiving confirmation is a screenshot someone sent on Slack, the manager's approval is buried in a reply-all, and the GL coding lives in a side spreadsheet. The procurement coordinator forwards it all to AP in three separate emails and hopes nothing's missing.

It usually is. AP bounces it back asking for the receipt. A second invoice gets paid twice because it slipped into two different handoff emails. An auditor later asks "show me the approval for this payment" and it takes an hour of digging to find it. The work isn't hard — it's just scattered, manual, and impossible to prove was done right. You do not need to be a developer to fix it.

What you'll build

A simple internal web tool for the procurement-to-AP handoff. You select the approved-to-pay invoices for this batch. The tool assembles each one into a single packet — pulling in its linked PO, receipt, approval records, and GL coding — and runs a completeness check that confirms every required piece is present and the invoice is genuinely in "OK to pay" status. Anything incomplete is held back with a clear reason, never shoved through. A coordinator reviews the batch, sees exactly which packets are clean and which are short, and approves the batch. Only then does the tool produce the AP-format CSV (the exact import columns your payment system needs, with payment terms and due dates so AP can schedule), a combined PDF per invoice bundling all the supporting documents, a handoff log, and an email to AP with the batch attached.

What's inside the Implementation Plan

The downloadable plan is a step-by-step file you paste into an AI coding agent. It opens by interviewing you about your business — your purchasing and AP systems, the exact columns in your invoice and PO exports, how you name vendors and code invoices, what counts as "OK to pay," which supporting documents are required, and your real approval rules — so the tool is tailored to your handoff, not a generic template. From there it walks the agent through the data model, the import, the packet assembly, the completeness check, the coordinator approval gate, and the AP export. Every step ends with a ready-to-copy prompt. There's also a "No API yet?" path: import your records from a Google Sheet or CSV and export a clean AP-format CSV plus combined PDFs — so you can build and use the whole tool today, with no integration to your systems at all.

The governance it includes (this is the point)

The whole reason to do this in a real tool instead of email is the controls it bakes in: login so only your procurement and AP team can use it; row-level security so you only ever see your own organization's invoices; a complete audit trail of who selected, assembled, approved, and exported what, and when; a hard human-approval gate where a coordinator reviews each packet for completeness and approves the batch before any AP file is generated; and duplicate guards keyed on invoice number plus supplier, so the same invoice can appear in exactly one handoff batch — never handed off, and never paid, twice.

Who it's for

Procurement and AP coordinators who today forward approved invoices to AP with the supporting documents scattered across emails, screenshots, and spreadsheets — and who get the inevitable "where's the receipt?" bounce-backs and dread the audit. If you can describe what a complete, ready-to-pay packet looks like, you can build this.

You've got this — start with the plan, paste the first prompt, and answer a few questions about your handoff. Your first clean packet is minutes away.
