# Supplier invoice coding and approval

Read incoming supplier invoices, match them to purchase orders and past coding, and route each one to the right approver with the draft entry ready.

[Talk through this workflow](https://lidvizion.ai/contact/?need=ai-workflow&from=%2Fuse-cases%2Finvoice-coding-and-approval%2F#write) · [Automate the repeatable](https://lidvizion.ai/services/automation/)

Where it starts

## The trigger.

A supplier invoice arrives by email, upload or supplier portal.

How it runs today

- Invoices are keyed into the accounting system by hand.
- Coding depends on who remembers how a supplier was coded last time.
- Approvals stall in inboxes and late fees creep in.

The workflow

## Four bounded steps.

Each step has an owner and a stop rule.

1. 01 / Read
   Extract supplier, amounts, dates and line items from the invoice.
2. 02 / Match
   Check against the purchase order, receipt and previous coding for that supplier.
3. 03 / Draft
   Prepare the accounting entry with suggested codes and flag any mismatch.
4. 04 / Approve
   Route to the budget owner; approved entries are posted and anything unusual goes to finance.

Where people stay in control

## Approval points.

- A budget owner approves every invoice before it is posted or paid.
- Mismatches, new suppliers and changed bank details always go to a person.

How we would measure it

## Against a baseline.

Measured before and after, on the same work.

### Time from invoice received to approved.

### Share of invoices coded without edits.

### Late payments and duplicate payments caught.
