A customer advice shows what the payer intended; the bank record confirms what arrived. Compare amount, currency, customer identity, references, invoice identifiers, and allocation lines before changing an AR entry or forcing a match.
What a payment mismatch can mean
A mismatch is not necessarily a bad invoice match. It can begin at several different points: the bank transaction or remittance never reached the platform, document extraction produced incomplete values, fields were mapped incorrectly, matching rejected a valid transaction, an allocation did not clear the intended open item, or the payment was not posted where expected.

Keep the bank receipt and invoice application distinct while diagnosing. Microsoft Dynamics 365 Business Central supports reconciling a bank account without applying payments at the same time, which can help establish whether cash receipt recognition or invoice application is the problem. Microsoft Learn documents the separate reconciliation and application workflows.

Establish what was actually received
Obtain the bank statement line or other bank-confirmed payment proof, the customer’s remittance advice if available, and the relevant open invoice or credit memo records. Confirm the receipt belongs to the expected bank account and period. Do not treat the advice alone as proof that the bank received the stated amount: Salesforce distinguishes payment advice, which represents the customer’s claim about intended payment, from bank payment proof, which confirms the receipt. Salesforce describes comparing the advice and bank proof with open invoices.

-
Confirm the source records reached the platform
Check the bank-feed or statement-import status and verify that the advice or remittance document was ingested. Inspect the source or staging records for transaction date, amount, currency, payer or reference, invoice details, and batch or document identifier. A correct payment can appear unmatched if a connector failed, source data is missing, a content refresh is stale, or extraction returned no usable data. Salesforce lists these among its documented troubleshooting cases.
-
Compare extracted values with the original documents
For each field used in matching, compare the platform’s extracted value with the source file. Check especially for a blank or shifted invoice number, truncated payment reference, incorrect decimal interpretation, or missing currency. Then confirm that transforms or mappings deliver the values in the required fields and data types. Salesforce’s documented workflow extracts structured data with Document AI and transforms it into Billing fields before reconciliation; a mistake at this stage can prevent matching even when the underlying receipt is valid.

Check match fields and allocation lines
Start with currency where the platform uses currency matching. Salesforce checks currency ISO codes before evaluating other match criteria. Then compare the bank-confirmed amount with the remittance total and open balances, along with payer or customer identity, payment reference or bank text, invoice numbers, and open-entry status. Work out whether the receipt should clear one invoice or several and whether the remittance includes a partial payment, credit, discount, deduction, or other adjustment.

Review candidates before changing or posting anything
Open the unmatched transaction and compare suggested invoices or ledger entries with the source evidence. A platform suggestion is a candidate, not proof that the allocation is correct. Business Central allows users to review and change automatic applications before posting and provides a manual application path for cases that do not apply automatically. Salesforce likewise directs AR staff to review matched and unmatched reconciliation records.
Keep a clear reason for any manual allocation so the record shows which evidence supported it. If the correct open entry is missing, locate it or route the item for investigation rather than selecting an unrelated invoice.

Correct the cause, then post only when supported
If the source import or mapping is wrong, correct and reprocess it using the platform’s controls. If the receipt is real but an amount difference remains unexplained, leave it in the appropriate exception workflow; do not force a match or create an unsupported write-off. When useful, reconcile the bank view separately from invoice application to identify which stage is out of agreement.

Find the likely cause from the symptom
| Symptom | Check first | What to do next |
|---|---|---|
| Payment is absent from reconciliation | Bank-feed or statement-import status; source period and account; connector status; advice or document ingestion. | Confirm the source transaction exists and the ingestion path completed before changing ledger records. Salesforce lists connector failures and missing data as possible causes. Salesforce Help. |
| Payment exists, but advice data is blank or incomplete | Extraction result; content refresh or processing status; field transforms and output data types. | Compare extracted values with the original document and correct the processing or mapping issue. Salesforce lists stale Process Content refresh and empty Document AI output as troubleshooting cases. Salesforce Help. |
| Customer is right, but the invoice is wrong or no invoice matches | Invoice reference, payment text, customer identity, open-entry status, and whether the receipt covers multiple invoices. | Review the suggested entry and confirm it exists and is open. In Business Central, a related ledger entry may not exist; manually apply only when the evidence supports the allocation. Microsoft Learn. |
| Amount differs | Bank-confirmed receipt versus remittance total and open balances; partial payment, deduction, credit, or multi-invoice allocation. | Identify and document the reason for the difference. Business Central identifies differing amounts as a possible reason automatic application fails; Salesforce compares advice, bank proof, and invoices. Microsoft Learn · Salesforce Help. |
| Currency differs or matching rejects the payment | Currency on the advice, bank proof, and invoice; expected bank account and currency. | Resolve a source-data or configuration inconsistency before overriding a match. Salesforce checks currency ISO codes as part of its reconciliation workflow. Salesforce Help. |
| Bank agrees, but AR still shows an invoice open | Whether the receipt was applied to the correct open item and posted to the intended ledger or account. | Check invoice application separately from bank reconciliation. Business Central documents these as distinct operations. Microsoft Learn. |
Platform details that affect the investigation
Salesforce Billing
Salesforce’s documented workflow ingests payment advice and payment proof, extracts structured data with Document AI, transforms it into Billing fields, and uses reconciliation transforms to compare advice with bank proof and open invoices. Its troubleshooting guidance includes connector failures, missing data, stale Process Content refresh, and empty extraction output. The feature is documented for Lightning Experience in Enterprise, Unlimited, and Developer editions with a Revenue Cloud Billing license. See Salesforce’s Automate Payment Reconciliation documentation.
Microsoft Dynamics 365 Business Central
Business Central documents importing bank statements or feeds into the Payment Reconciliation Journal, applying payments to open ledger entries using payment text and entry information, and reviewing or changing suggested applications before posting. It also supports reconciling a bank account without simultaneously applying payments. Microsoft Learn’s page, “Apply payments automatically and reconciling bank accounts,” was last updated 2024-07-25. Read the Business Central documentation.
SAP Cash Application
SAP describes Cash Application as cloud microservices that use machine-learning intelligence for incoming bank statement and lockbox matching, customer account identification, payment-advice extraction, and related receivables workflows. SAP notes that one payment can match multiple open items, and AI-based features require additional entitlement and authorization. Exact screens and steps depend on the SAP deployment. SAP Help Portal explains SAP Cash Application.
