AP Automation
for SAP S/4HANA

Stampli delivers real-time, bi-directional AP and procurement automation that plugs directly into SAP ECC or S/4HANA without middleware, firewall changes, or custom development.

Stampli SAP S4HANA ERP Integration

How does SAP S/4HANA fall short for accounts payable?

SAP S/4HANA is a powerful system, but companies running core FI and MM modules often face complexity and manual workarounds without investing in additional SAP automation tools.

Invoices get stuck over minor mismatches

Price, quantity, or tax discrepancies block entire invoices, requiring complex screen navigation to resolve

Two different invoice entry paths

PO-based invoices use one workflow, non-PO invoices another, forcing AP teams to learn separate processes

Hard to find root cause of blocks

Error details hide in multiple screens, often requiring IT or SAP super-users to diagnose issues

Hard-wired approval flows

Changing approvers requires IT change requests that can take days or weeks to implement

Layering procure-to-pay seamlessly on SAP S/4HANA

Smart invoice coding & data integrity

Code complex SAP invoices in seconds with AI-driven automation and built-in field validation

Comprehensive PO management & matching

Handle all SAP PO types with live receiving data and many-to-many matching capabilities

Continuous, secure SAP synchronization

Bi-directional bridge syncs data every few minutes without firewall headaches or delays

User-centric experience & collaboration

Purpose-built AP interface with dynamic workflows that adapt to real-world scenarios

Our SAP S/4HANA integration is built in advance, built in-house, and built to completion.

Unlike other solutions that rely on middleware or custom configurations, Stampli provides a pre-built connector using standard BAPIs and a lightweight bridge for seamless integration.

Stampli streamlines invoice entry by pulling forward SAP master data, enforcing field relationships, and applying company‑specific defaults before anything reaches the ERP. The result is faster coding, fewer errors, and cleaner analytics without extra effort from AP.

  • PO‑type aware filters – guides coders to the right values based on the SAP PO type selected
  • Header‑level tax coding – lets AP enter a single tax code/amount that propagates across every line
  • Vendor default values – automatically applies vendor‑specific tax, 1099, bank, and distribution settings
  • Baseline date rules – configurable logic (or manual override) to derive the correct payment baseline date
  • Profitability segment coding – captures fields like product, sales order, and customer for margin analysis
  • Non‑deductible tax allocation – routes non‑deductible taxes to expense accounts instead of tax codes
  • Unplanned delivery cost allocation – adds and proportionally distributes unexpected delivery costs across lines
  • Additional SAP PO expense types – imports freight, storage, and other fees so they post correctly the first time
  • Native SAP fields in Stampli – exposes G/L, WBS, Profit Center, and more for precise coding
  • Internal‑order filtering – imports only the internal‑order types you actually use, keeping lists clean
  • Document type by vendor location – auto‑assigns document types according to vendor and company country codes

Stampli ingests every flavor of SAP PO and keeps live receiving data at AP’s fingertips, so even complex service, freight, split‑vendor, and partial‑ship scenarios flow straight through without manual workarounds.

  • All SAP PO types supported – limit, service, freight, and planned services included
  • Freight POs & multi‑currency conditions – matches freight charges in any currency
  • One PO ↔ multiple invoices (and vice‑versa) – perfectly handles partial receipts and cross‑department orders
  • Alternate payee vendors – pays the correct party when the PO specifies a different vendor
  • 2‑way & 3‑way matching – leverages SAP receiving data for straight‑through processing
  • Credit memos from billed POs – generates credits directly from the original PO‑based invoice
  • PO search by BOL/SES/delivery note – find the right PO fast, even with shipping references
  • Subsequent credits & debits – create follow‑up adjustments against billed or partially billed POs
  • Live receiving status sync – shows up‑to‑the‑minute receipt quantities inside Stampli
  • Invoices from scheduling agreements – automates billing against long‑term SAP contracts
  • Freight cost & multi‑vendor splits – splits additional costs across vendors on the same PO
  • PO header data mapping & live sync – brings every PO header/line field into Stampli within a two‑hour window

A bi‑directional integration keeps master data, POs, invoices, payments, and receipts in constant sync—without firewall headaches or list‑load delays—so finance always works with real‑time information while IT stays hands‑off.

  • Secure, automated on‑prem connector – one‑time firewall / domain setup, then hands‑off operation
  • Real‑time bridge with auto‑updates – no port openings; the bridge self‑updates without IT involvement
  • Lists stay in sync (5‑min pulls / 2‑hr pushes / on‑demand) – coders never wait for lists to load
  • Header & line‑level invoice sync – every field, memo, and account remains aligned between systems
  • PO data sync – item, rate, quantity, description, and more flow in for precise matching
  • Vendor payment detail sync – Direct Pay brings across bank accounts and payment methods
  • Payment method field sync – mirrors SAP’s payment‑method selection on each invoice
  • Internal‑order type filtering – choose which orders to import to avoid clutter
  • Multi‑entity framework – switch entities without separate Stampli accounts
  • Bi‑directional document links – jump between SAP and Stampli with a single click
  • Full invoice & credit memo export – creates native SAP docs plus the corresponding journal entries
  • Storage‑saving PDF links – link to Stampli images instead of paying SAP storage fees

Because Stampli is built for invoice processing—not generic ERP tasks—finance and business users can code, approve, and resolve issues in minutes without training or IT tickets.

  • Purpose‑built AP interface – dramatically shorter learning curve than SAP’s generic screens
  • Enhanced auto‑complete & search – find master data without knowing exact syntax
  • Native‑language list values – mirror SAP’s languages so global users choose the right value quickly
  • Dynamic approver routing – add approvers on the fly without creating new definitions
  • On‑invoice fee entry – add non‑PO fees directly in Stampli instead of returning to SAP

ERP Resources

Our pre-built connector integrates with SAP ECC or S/4HANA using standard BAPIs and requires minimal IT involvement. The lightweight bridge connects through standard Port 443 with no middleware installation needed. Once deployed, the connector is secure, auto-updating, and completely hands-off with no ongoing IT maintenance required.

Stampli supports all SAP PO types including limit, service, freight, and planned services out of the box. We handle complex scenarios like one‑PO‑to‑multiple‑invoices, alternate payee vendors, unplanned delivery costs, and multi‑currency freight charges without requiring custom configuration or workarounds.

While invoice images are stored securely in Stampli’s cloud, we create hyperlinks in SAP so auditors can access invoices directly from FB03 with one click. This maintains the complete audit trail while saving you SAP storage fees. All invoice metadata, approval history, and document links remain fully traceable within SAP.

Un‑exported invoices queue safely in Stampli if connectivity is interrupted. The connector retries automatically and alerts you after failures. Nothing posts to SAP until confirmation is received, ensuring zero data loss and no duplicates. All document integrity is maintained throughout any temporary connectivity issues.

Stampli syncs POs, vendors, and master data every 2 hours, with critical matching data available in real‑time. Document posting happens every 5 minutes, and you can trigger manual syncs on demand. PO line‑level data including receiving status is always current, so AP teams never work with stale information when matching invoices.

No. The same connector and transports are S/4HANA‑certified. You’ll simply point the RFC destination to the new system and run a delta transport with no re‑implementation required. Stampli’s integration is designed to work seamlessly across SAP versions, making it a future‑proof investment during your migration.
