2-way vs 3-way matching
2-way vs 3-way matching
and when to use each
2-way checks the invoice against the order. 3-way also checks the goods arrived. Here is when to use each.
The question: What is the difference between 2-way and 3-way matching?
The short answer
2-way matching compares a supplier invoice with its purchase order: same items, same quantities, same agreed price. 3-way matching adds the goods receipt, so the invoice is only paid for what actually arrived. In InvoiceIQ AP by Analytos the difference is one policy setting, chosen per vendor or company-wide, not a different product.
- PO exists
- Vendor identity
- Price within 2%
- Quantity ≤ received
- Not already billed
Try it:
switch between 2-way and 3-way
- PO exists
- Vendor identity
- Price within 2%
- Quantity ≤ received
- Not already billed
All three have to agree before the bill can be paid.
2-way match
“Is this the bill I agreed to?”
Compares the bill against the order. Same items, same quantities, same price you agreed? Then it can be paid. It cannot tell you whether anything arrived — so it suits services, subscriptions and blanket orders.
3-way match
“…and did it actually arrive?”
Adds the goods receipt. Ordered, received and billed all have to agree before a penny moves. If the goods are still on their way, the bill simply waits — and releases itself the night the receipt is logged.
Side by side
| 2-way | 3-way | |
|---|---|---|
| Documents compared | Invoice and purchase order | Invoice, purchase order and goods receipt |
| Catches | Wrong price, items never ordered | Everything 2-way catches, plus goods that never arrived |
| Misses | Whether anything was delivered | Inspection or quality acceptance (that is 4-way) |
| Use it for | Services, subscriptions, utilities, blanket orders | Physical goods received into a warehouse or plant |
| In InvoiceIQ AP | Receipts are not consulted; the bill is raised from the order | The bill is composed from the receipt |
A third tier: invoices with no purchase order
Rent, utilities and professional fees have no order to match. InvoiceIQ AP’s non-PO tier marks the order and receipt checks as not applicable rather than simply off, while the duplicate guard, the total check and your own rules still run.
Is this a fit?
A good fit when
- 2-way: services, subscriptions and blanket POs
- 3-way: raw materials, components and finished goods
Not the right tool when
- 2-way where goods are received (you lose the delivery check)
- 3-way where nobody records receipts (every bill will wait)
Evidence

Frequently asked
questions
For physical goods, yes. For services there is nothing to receive, so 3-way would hold every bill.
3-way plus inspection or quality acceptance. InvoiceIQ AP does not ship it today; the check model can accommodate it as one more check.
Yes. The policy is a vendor default, with a company default behind it.
