Supplier statement reconciliation, sorted

Supplier statement reconciliation means checking every supplier's statement against your own purchase ledger, line by line, to confirm invoices, payments and credits all match. Done manually, it's slow and easy to get wrong. Open ECX automates the matching and flags only the exceptions, so your team only looks at what's wrong.

Supplier statements pile up fast

Checking every one against your ledger manually gets harder with every supplier you add. This guide pulls together everything your finance team needs on statement reconciliation: what it is, how the matching works, and what changes when you automate it. Whether you're comparing software, building the case for a project, or just want a straight answer to "what is this, really", you're in the right place.

Start here: the foundations

Our guides cover what statement reconciliation is, how it works, and why it's worth automating.

How the matching works, in six steps

  1. Statements come in. Your supplier sends their statement, by email, PDF or portal.
  2. The ledger gets pulled. Your purchase ledger for that supplier is pulled in automatically.
  3. Every line gets checked. Each invoice, payment and credit on the statement is matched against the ledger.
  4. Mismatches get flagged. Anything that doesn't match, like a missing invoice, a duplicate payment or a credit you're owed, is flagged as an exception.
  5. Your team reviews the exceptions. Everything that matched cleanly needs no input, so AP only looks at what's wrong.
  6. The reconciliation gets logged. Once exceptions are resolved, the result is recorded for your next audit.

Staff time saved, Direct Heating & Plumbing

"Previously, we were manually ticking off each statement or performing VLOOKUPs in a spreadsheet to reconcile larger suppliers, which took a lot of valuable time. Now, Open ECX automatically reconciles any matching items to our ledger, and we only need to focus on any discrepancies."

Ryan Davies, Finance Manager, Direct Heating & Plumbing

Questions finance teams ask us

What is supplier statement reconciliation?

It's the process of comparing a supplier's statement against your own purchase ledger to confirm every invoice, payment and credit lines up. We flag anything that doesn't as a discrepancy to resolve.

How often should we reconcile supplier statements?

Monthly is the common baseline, though high-volume suppliers often get reconciled weekly. Automation makes the frequency a setting, not a staffing decision.

Is SOX compliance relevant to a UK business?

Only if you're SEC-registered or a subsidiary of a US-listed parent whose results roll into that parent's accounts. Most UK private companies sit outside SOX's direct scope, though the same control discipline still pays off ahead of an audit or an exit.

Can statement reconciliation be automated end to end?

Matching, flagging and reporting can run automatically. Exceptions still go to a person, which is exactly where the time should go.

What's the difference between statement reconciliation and invoice matching?

Invoice matching checks one invoice against a PO and a goods receipt before payment. Statement reconciliation checks the supplier's whole statement against your ledger after the fact. One stops errors, the other catches what got through.
