SAP Business One Accounts Payable: Invoice Entry, Payment Wizard and AP Automation

Last updated: November 5, 2026 · Independent guide · We do not sell rankings or coverage.

SAP Business One accounts payable runs on three native pieces: the A/P invoice in the Purchasing – A/P module, approval procedures that hold documents as drafts until an authorizer signs off, and the Banking module, where you pay vendors one at a time through Outgoing Payments or in batches through the Payment Wizard. This guide covers the setup in the order an administrator does it, then shows where AP automation add-ons such as Tipalti, DOKKA, Rillion or Stampli take over.

Before you start

  • Documentation version. Menu paths here come from SAP’s public 9.1 and 9.2 help library and SAP Learning. Confirm each path in your own release’s help file before you train staff.
  • Authorizations. SAP Learning states that users who set up or use approvals need the general authorizations for Approval Stages, Approval Templates, the Approval Status Report and the Approval Decision Report (SAP Learning, no date shown).
  • Banking master data. Set up at least one house bank account linked to a G/L cash account, because the Payment Wizard groups payment methods by that account (SAP Help, Payment Wizard Step 5, no date shown).
  • Purchasing flow decided. Agree whether stock items will always pass through a purchase order and goods receipt PO before the A/P invoice.

Step 1: Turn on approval procedures

Go to Administration > System Initialization > General Settings, open the BP tab and select the approval procedures checkbox. SAP’s 9.2 help labels it Activate Approval Procedures, with a second checkbox, Activate Approval Procedures in DI, to apply approvals to documents created through the DI API (SAP Help, Setting Up Approval Procedures, no date shown). Turn the DI option on if an integration or add-on creates A/P invoices, otherwise those invoices bypass your approval rules.

SAP Learning notes that once templates are active you cannot switch the feature off, only deactivate individual templates.

Step 2: Create approval stages

Open Administration > Approval Procedures > Approval Stages. Give the stage a name, set the number of approvals and rejections required, and list the authorizers (SAP Help, Creating an Approval Stage, no date shown). SAP’s help says it is useful to have more than one authorizer per stage so requests keep moving when an authorizer is unavailable.

Step 3: Build the A/P invoice approval template

Open Administration > Approval Procedures > Approval Templates. On the Originator tab, add the AP clerks whose invoices need approval. On the Documents tab, select A/P Invoice. On the Stages tab, add one or more approval stages. On the Terms tab, choose Always or When the Following Applies, for example a document total above a threshold (SAP Help, Creating an Approval Template, no date shown).

Terms can also call a user query that returns True or False, for example to route by vendor. SAP Learning warns that terms and queries read header fields only. For routing design, see our guide to invoice approval workflows.

Step 4: Set up payment methods and vendor payment data

Go to Administration > Setup > Banking > Payment Methods. For each outgoing method, set the payment type to Outgoing, the payment means to Check or Bank Transfer, and the house bank. Grouping options (pay-to address, pay-to bank, currency, due date) decide which invoices the wizard combines into one payment (SAP Help, Payment Methods – Setup, no date shown).

Then open each vendor’s business partner master data and, on the Payment Run tab, include the payment methods the wizard may use for that vendor (SAP Help, Paying Negative Totals Using the Payment Wizard, no date shown). SAP’s wizard procedures ask you to confirm this tab includes the method you will select in the run. If you want to net vendor credit memos against invoices, also select Enable Negative Payment for Payment Wizard on the General tab of Document Settings and define a negative payment method.

SAP also lets you define payment blocks and assign them to a vendor or a single document, then use the block as a selection criterion in the wizard. Use this to hold disputed invoices out of a run (SAP Community, Optimizing the Payment Wizard Run, no date shown).

Step 5: Enter the A/P invoice

Open Purchasing – A/P > A/P Invoice, enter the vendor, then fill the Contents, Logistics and Accounting tabs and choose Add (SAP Help, Creating Purchasing Documents, no date shown). For stock purchases, use Copy From to pull in the goods receipt PO. Copy From opens the Draw Document wizard, where you can pick several base documents and adjust quantities (SAP Learning, Purchasing Items, no date shown).

The posting depends on the base document. SAP Learning states that an A/P invoice based on a goods receipt PO updates the vendor balance without changing stock, while an A/P invoice entered without a goods receipt increases stock when posted. Enter the vendor’s invoice number in the vendor reference field every time. SAP says you can decide, per document type, whether duplicate reference numbers are allowed (SAP Community, Keep Track of Reference Numbers, no date shown), and blocking them on A/P invoices is the cheapest control against paying twice. Our guide to duplicate payment detection covers other checks.

Step 6: Approve the invoice

SAP Learning states that when an invoice meets a template’s terms, SAP Business One saves it as a draft with the status Draft [Pending] and notifies the authorizers. Authorizers open Administration > Approval Procedures > Approval Decision Report, filter the list and approve or reject each document. Global Update approves or rejects several documents at once with a shared remark (SAP Help, Generating the Approval Decision Report, no date shown).

Approval does not post the invoice. According to SAP Learning, the draft moves to Draft [Approved] and the originator must open it and add it, at which point the document number is assigned.

Step 7: Pay individual invoices with Outgoing Payments

For one-off payments, open Banking > Outgoing Payments > Outgoing Payments, select the vendor, tick the open invoices and choose Payment Means to record check, bank transfer, credit card or cash (SAP Help, Payment Means, no date shown). Paying a document triggers an automatic internal reconciliation of the invoice and payment, according to SAP Learning.

Step 8: Run the Payment Wizard

Open Banking > Payment Wizard. SAP’s help library documents eight steps, one page per step:

  1. Payment Run Selection. Start a new run or reopen a saved one (SAP Help, Step 1, no date shown).
  2. General Parameters. Set the run date, choose Outgoing and Check or Bank Transfer (SAP Help, Step 2, no date shown).
  3. Business Partner Selection Criteria. Add vendors by code range, group or properties (SAP Help, Step 3, no date shown).
  4. Document Parameters. Filter by posting date, due date and balance due, with tolerance days and a minimum cash discount percentage (SAP Help, Step 4, no date shown).
  5. Payment Method Selection Criteria. Choose methods and a maximum outgoing amount, and check the Expected G/L Balance.
  6. Recommendation Report. Review each proposed payment. Green can proceed and red is blocked. Edit amounts for partial payments and use Non-Included Trans. to see what was left out (SAP Help, Step 6, no date shown).
  7. Save Options. Save criteria only, save the recommendation (reserving the transactions), run a payment order, or execute the payment run (SAP Help, Step 7, no date shown).
  8. Payment Run Summary and Printing. Print payments, checks and summary reports (SAP Help, Step 8, no date shown).

Use Save Recommendations as your review point: send the Step 6 report to the controller, then reopen the run and execute it once approved. Our payment run explainer covers the controls.

Common mistakes and how to fix them

  • A vendor never appears in the wizard. The vendor’s Payment Run tab lacks the method chosen in Step 5, the vendor has a zero balance, or a payment block applies. Fix the master data, then rerun from Step 3.
  • Payments made through the wizard skip approval. SAP Learning states that outgoing payment approval templates apply only to manually created payments, not to the Payment Wizard. Restrict who may execute runs and review the saved recommendation.
  • Approved invoices are never posted. The originator has not added the approved draft. Check the Approval Status Report daily.
  • Stock is counted twice. An A/P invoice was entered without copying from the goods receipt PO, so both documents increased stock. Always use Copy From for received goods.
  • Integration invoices bypass approvals. The DI approval checkbox was left off in General Settings.

Limitations of native SAP Business One AP

SAP’s documented A/P invoice process starts with a user keying the vendor and lines. The help pages we reviewed describe no invoice capture from PDF or email. Approval terms read header fields only, so line-level routing by cost center is a development task. Copying from a goods receipt PO carries quantities forward, but SAP describes no exception queue for price or quantity variances. Our guide to the three-way match lists what a full match control checks.

Tipalti, which sells an add-on, states that SAP Business One alone does not provide end-to-end AP automation or automated invoice matching (Tipalti, updated October 13, 2026).

When companies add an AP automation tool

Teams usually add a tool when manual keying becomes the bottleneck, approvers work outside SAP Business One, or vendors are paid in several countries. The add-ons below publish SAP Business One integrations. All capability statements are the vendors’ own, checked on November 5, 2026.

Add-on Connection to SAP Business One (vendor claim) Scope Published price
Tipalti Prebuilt, SAP-certified, two-way sync of vendors, invoices and payments Capture, matching, approvals, global payments, multi-entity Accounts Payable from $99/month plus transaction fees
DOKKA Connects through the SAP Business One Service Layer and posts AP journal entries with the source file Capture, matching of purchase orders, goods receipts and invoices, approval chains Not published
Rillion Continuous sync of approvals, postings and payments Two- and three-way matching, coding, approvals, optional Rillion Pay Not published on its SAP Business One page
Stampli File integration syncing invoice coding and payment data Invoice coding and payment data sync Not published on its SAP Business One page

The key differences are sync depth and who pays the vendor. Tipalti (Tipalti, updated October 23, 2026) and Rillion (Rillion, no date shown) can take over payments, which replaces the Payment Wizard for those vendors. DOKKA (DOKKA, no date shown) and Stampli (Stampli, no date shown) describe posting invoice data back to SAP Business One. DOKKA’s page does not mention payments, and Stampli’s page says invoice payment data syncs back to SAP Business One. In a demo, confirm whether matching reads purchase orders and goods receipts live from SAP Business One.

How we researched this

We read the top-ranking pages for “SAP Business One accounts payable” on November 5, 2026, including glossary pages from Hyperbots, a sponsored SAP PRESS post written by DOKKA, Tipalti’s SAP Business One guide and DOKKA’s add-on list. None gave menu paths or explained the Payment Wizard approval gap. Every step comes from SAP Help or SAP Learning, and every add-on claim from the vendor’s own page.

Frequently asked questions

Can SAP Business One require approval before an A/P invoice is posted?

Yes. Approval templates under Administration > Approval Procedures can cover A/P invoices for named originators, either always or when terms such as document total are met. The invoice is held as a draft until it is approved and the originator adds it.

Do approval procedures apply to the Payment Wizard?

No. SAP Learning states that outgoing payment approval templates apply only to manual outgoing payments. Control wizard runs through authorizations and a review of the saved recommendation report before execution.

Why is a vendor missing from my Payment Wizard run?

Check that the vendor’s Payment Run tab includes the method used in the run, that it has an open balance, that no payment block applies, and that Step 4 filters do not exclude its invoices. The Non-Included Transactions report in Step 6 lists what was left out.

Does SAP Business One read vendor invoices with OCR?

SAP’s help pages for the A/P invoice describe manual entry and no invoice capture. Teams that want capture add a tool such as Tipalti, DOKKA or Rillion, which post coded invoices into SAP Business One.
