Integration pattern
SAP stays the system of record.
NexumFlow is the invoice-intelligence and workflow layer around it. The integration is scoped to the interfaces your SAP landscape already supports.
Resolve outside the posting transaction
Handle document extraction, mismatches and human approvals before sending a clean accounting transaction into SAP.
Write back through controls
Post approved invoices through configured APIs or file-based interfaces, preserving ERP responses and visible errors.
Workflow
From incoming document to SAP posting.
Capture and extract
Read invoice headers, lines, taxes and SAP references from email, PDFs and scans.
Validate the supplier invoice
Apply duplicate, GSTIN, tax, TDS, MSME and business-rule checks appropriate to the entity.
Match with SAP data
Compare the invoice with purchase-order and goods-receipt data at line level, including configured tolerances.
Route exceptions and approvals
Present the document and matching evidence together so approvers can decide without reconstructing the transaction.
Post and track the SAP response
Create the agreed SAP transaction only after approval; retain the document number or actionable posting error.
SAP variants
One product, landscape-specific integration.
| Environment | Typical read path | Typical write path | Scope decision |
|---|---|---|---|
| SAP S/4HANA | Released APIs, integration layer or approved extracts | Approved API or controlled interface | Cloud/on-premise topology and governance |
| SAP ECC | BAPI/RFC, middleware or file exchange | BAPI, IDoc or approved posting file | Available interfaces and change policy |
| SAP Business One | Service Layer or approved database/interface access | Service Layer transaction creation | Version, objects, network and authorization |
Why add NexumFlow

India-specific control gaps

- GSTR-2B and ITC exception visibility
- Section-wise TDS logic and evidence
- MSME 43B(h) payment-deadline tracking
Operational exception gaps
- Complex or poor-quality invoice documents
- PO and goods-receipt mismatches
- Approval evidence outside SAP
- Posting failures without a clear retry path
Questions
SAP invoice automation, answered.
Is direct SAP database writing required?
No. The integration should use the interface approved for your SAP version and governance model. NexumFlow does not require unsafe direct database writes.
Can the workflow run when SAP is temporarily unavailable?
NexumFlow uses durable workflows so a transient ERP outage can be retried while the invoice state and history remain visible.
How is the integration validated?
Start with read-only master and transaction data, validate matching and approvals in a controlled environment, then enable write-back after UAT and authorization testing.
