The impact
Routine checking is taken out of the way
The repeated extraction, matching and classification steps happen consistently without finance staff treating every invoice as a fresh manual task.
Exceptions rise to the surface
Missing POs, value differences and other discrepancies are separated from clean matches and presented with the reason they need attention.
Approvals stay controlled
Transactions that need authority are routed to the right person instead of being chased through inboxes.
Finance gets a clearer operational picture
Teams can see what has arrived, what has matched, what is waiting and where intervention is needed.
The problem
Supplier invoices rarely move cleanly from inbox to accounts. Someone has to open the document, identify the supplier, find the relevant purchase order, check totals and line items, apply coding, and decide what happens when something does not match.
At volume, routine checking consumes finance time while exceptions are chased through email or spreadsheets. The process becomes dependent on individual knowledge, and it is harder to see what is waiting, why it is stuck and who needs to act.
What the Application does
AIMAI built the Application to manage the invoice-to-approval workflow. It receives supplier invoices through an agreed channel, extracts the key data, retrieves the relevant open purchase orders and compares the records using agreed rules and tolerances. It classifies matches and exceptions, explains the reason for a discrepancy and routes the right item to the right person for review or approval. Where an integration is agreed and technically scoped, approved data can then pass into the finance system.
How it works
- Invoice received
- Supplier and invoice data extracted
- Relevant purchase order retrieved and checked
- Match or exception classified
- Discrepancy or approval routed to the right person
- Approved record passed into the finance workflow
What it uses
- Supplier invoices
- Open purchase orders
- Supplier and coding records
- Matching rules and tolerances
- Approval matrix and project or job references
What it produces
- Confirmed invoice and PO matches
- Clearly classified discrepancies
- Exception and approval queues
- Structured accounting records
- Throughput, ageing and backlog reporting
- Audit history of checks, approvals and overrides
Where people stay in control
Finance remains in control of exceptions, approvals and posting rules. The Application applies the agreed logic and holds anything outside those rules for review. It does not remove finance approval from transactions that require judgement or authority.
The result
The finance team works from an exception-led process rather than giving every invoice the same manual attention. Routine checks happen consistently, problems are surfaced with context, approvals stay visible and the decision history is captured in one workflow.
Could something similar work in your business?
It is likely to be relevant if:
- You process a meaningful volume of supplier invoices.
- People repeatedly match invoices against purchase orders by hand.
- Discrepancies are managed through email, spreadsheets or individual knowledge.
- Approval rules vary by amount, supplier, project or transaction type.
- Finance staff spend too much time chasing routine exceptions.
