SAP Business One for Retention and RA Billing

The retention process is bolding back a portion of payment to vendors who work for your organization. For example, the retention amount is released to the vendor when certain expectations are achieved or on a specified date that your vendor has agreed upon.

Running account (RA) billing refers to periodic or progressive billing used in long-term projects, such as construction, infrastructure, or contracting, where a vendor or contractor is paid incrementally as work progresses rather than through a single lump-sum payment at the end.

SAP Business One handles retentions and running account billing (often used in construction and project-based industries) by using tax withholding definitions, customized accounts payable and receivable workflows, and project cost accounting. Here, we’ll discuss SAP Business One for retention and RA billing.

Handling Retentions in SAP Business One

Unlike enterprise SAP ECC or S/4HANA, which use specific logistics invoice verification transactions like MIRO and special G/L indicators, SAP Business One handles retentions primarily through tax withholding or dedicated retention or holdback G/L accounts handled through invoice processing.

1. Withholding Tax Setup

Configure retentions by navigating to management, definitions, finance, taxes, and tax withholding.

2. Invoice Configuration

Set the category to invoice instead of payment.

3. General Ledger Integration

Allows the tax withholding checkbox under management, definitions, finance, and general ledger account determination.

4. Application

The retention percentage is automatically withheld and routed to a liability or retention account when you post the A/P or A/R invoice.

Running Account Billing (On-Account and Progress Billing)

Running account billing tracks continuous work-in-progress, running ledgers, and periodic installments against a project or contract.

1. Accounts Payable and Accounts Receivable Down Payments

Use down payment requests and down payment invoices to bill or pay fractions of a total contract without closing the base purchase order or sales order.

2. Project Costing Integration

Connect marketing documents like purchase orders, sales orders, and A/P and A/R invoices directly to specific projects or cost centers to maintain a running balance of work delivered versus billed.’

3. A/P Reporting

Review outstanding balances, running totals, and scheduled release dates for withheld amounts using financial and accounts payable reports.
