Depending on the product and setup, it can also return posting results or updated balances to the ERP. Unmatched or unclear payments still need a defined review path; a connection does not make every transaction automatic.
How the ERP and AR automation work together
The ERP provides the accounting context: customer records, invoices, open receivables, and payment information. AR automation uses some of that data to carry out receivables tasks, then may send results back to the ledger. The exact data exchanged, timing, and direction depend on the product, ERP edition and release, available interfaces, configuration, and licensing.
- Supply receivables context. The automation needs relevant customer, invoice, open-item, and payment data. Rex describes its integration as reading current invoice, customer, and payment data through an API or supported integration; that is a vendor description, not independent validation. Rex integration overview.
- Process receivables work. Depending on the solution, this can include invoice delivery, payment collection, remittance matching, cash application, and collections follow-up. Flywire describes these as elements of its invoice-to-cash platform. Flywire B2B platform.
- Return outcomes to the ERP. Some integrations write applied-cash results or updated balances back to ERP records. Do not assume that a connection is bidirectional or real-time: those behaviors are product- and configuration-specific. Rex and Flywire describe ERP data exchange for their offerings in their respective product materials (Rex; Flywire).
- Route unresolved items. A payment that cannot be matched or posted may need investigation. In SAP’s documented contract-account example, unresolved payments become clarification cases; SAP Cash Application can analyze remittance notes and propose matches with confidence ratings. Configuration determines whether a proposal is reviewed, followed up, or used to clear a receivable automatically. SAP Cash Application documentation.
Which receivables tasks can be automated?
Automation can support several stages of invoice-to-cash, but a product’s advertised scope is not proof that every feature is available for every ERP connection. The ERP remains the accounting context for customer invoices and payments. Microsoft Dynamics 365 documentation, for example, covers multiple forms of payment and centralized payments across legal entities. Microsoft Dynamics 365 accounts receivable documentation.
- Invoice and customer-data handling: use ERP customer and invoice information in receivables workflows, subject to supported data mappings and interfaces.
- Payment and remittance matching: compare payment references and remittance details with open receivables.
- Cash application: propose or perform application of receipts against invoices. SAP documents confidence-rated proposals when its configured clearing logic does not resolve a payment automatically.
- Collections follow-up: help coordinate follow-up work, where the relevant product and ERP connection support it.
- Posting and balance updates: return application outcomes to ERP records when the integration supports write-back.
These are possible workflow capabilities, not a promise that one integration includes all of them. SAP’s receivables API catalog lists distinct interfaces, including bank-statement posting and dispute management, which illustrates why the specific interface matters. SAP receivables APIs.

Where people still need to step in
Cash application depends on evidence that connects a receipt to the right customer and open item. A missing or ambiguous reference, an amount that does not fit the invoice, or other unresolved details can prevent automatic posting. In SAP’s contract-account example, the system creates clarification cases for payments it cannot automatically post and adopts them into a clarification worklist. SAP Cash Application can then analyze remittance notes and present confidence-rated proposals. This is a documented SAP flow, not a universal description of every AR platform.
“For payments that cannot automatically be posted to a contract account, the system creates clarification cases and adopts them into a clarification worklist.”
The practical question is not only how often a system can match payments, but what happens when it cannot. Confirm who reviews the queue, what evidence they can see, whether a proposal requires approval, and how corrections are recorded. No neutral automation-rate, matching-accuracy, time-saving, or days-sales-outstanding figure is established by the sources cited here.

Ask vendors to confirm behavior for the exact ERP product, deployment, and release in scope. “Connected” does not by itself establish which records move, how quickly they move, whether updates return to the ERP, or how failures are handled.

- Supported system and release: identify the precise ERP product, deployment type, version or release, and connection architecture. SAP documents functional constraints for some non-SAP and older SAP connections, so support should be confirmed rather than inferred. SAP connection documentation.
- Data coverage and direction: list the customer, invoice, open-item, payment, remittance, dispute, and posting data involved. Establish which system is authoritative for each record and whether the integration reads, writes, or both.
- Sync timing and failures: agree on expected synchronization timing, how errors or missed updates are surfaced, and who monitors and corrects them. These details must be confirmed for the proposed integration.
- Matching and controls: ask how match confidence is used, what enters a human review queue, which thresholds allow clearing or write-offs, and what audit trail is retained.
- Master data and multiple entities: check customer and vendor mapping, legal-entity requirements, and whether data must be replicated between systems. SAP documents a two-system scenario requiring Customer/Vendor Integration and asynchronous distribution. SAP Customer/Vendor Integration replication documentation.
- Interfaces, setup, and licensing: verify that required APIs or interfaces are available and enabled, that permissions and configuration are in place, and that the needed features are included in the commercial scope. SAP says its Cash Application add-on requires a separate license. SAP Cash Application documentation.
Ask for a walkthrough using representative transactions from your own workflow: a straightforward payment, a partial or ambiguous remittance, and a case that needs correction. Confirm what the ERP shows before and after each case, who handles exceptions, and which records provide the audit trail. Treat vendor descriptions as claims to validate against the proposed configuration.
