SAP SD Guide: Sales and Distribution and the Order-to-Cash Process
SAP SD runs the sell side - from order to cash. Here is what Sales and Distribution covers, the order-to-cash flow, pricing and credit control, and how it connects to the rest of SAP.
- SAP SD (Sales and Distribution) runs the sell side of the business - from a customer order through delivery to billing and cash - the order-to-cash process.
- It is built on the order-to-cash flow and the master data behind it (customer, material, pricing and credit), and it posts to finance at billing.
- This guide covers what SD does, the order-to-cash steps, pricing and credit control, and how SD integrates with MM and FICO.
If SAP MM runs the buy side, SAP SD (Sales and Distribution) runs the sell side. It takes a customer order and carries it all the way through to delivery, billing and the cash that lands in finance - the process known as order-to-cash. For any business that sells physical goods, SD is where revenue is captured and controlled in S/4HANA. This guide covers what SD does and how it fits together. For senior SAP help, Acqurio Tech provides SAP development and consulting.
What SAP SD Covers
SD manages the whole selling process: capturing sales orders, determining prices, checking credit and availability, organising deliveries and shipping, and billing the customer. It is the module that turns a customer's request into a priced, credit-checked order, into a delivery, and finally into an invoice and a receivable in finance. Alongside the transactions it also handles the sales master data and the pricing rules that make those transactions correct.
The Order-to-Cash Flow
The backbone of SD is the order-to-cash (O2C) process.
- Inquiry and quotation - optional pre-sales steps capturing interest and a formal quote.
- Sales order - the confirmed order, with pricing, credit check and availability check.
- Delivery - picking, packing and goods issue, which reduces inventory.
- Billing - the invoice to the customer, which posts the receivable and revenue to finance.
Pricing and Credit Control
Two areas decide whether SD protects the business or exposes it. Pricing in SD is driven by condition technique - a flexible framework of condition types for base price, discounts, surcharges, freight and tax - so the right price is calculated automatically from the customer, material and conditions. Credit management checks a customer's credit exposure before an order is confirmed, so a sale that would push them over their limit is blocked or flagged. Configured well, both run quietly; configured poorly, they cause wrong invoices and bad debt.
Master Data Behind SD
SD depends on clean master data: the customer (business partner) master for who you sell to and their terms, the material master shared with MM for what you sell, and condition records for pricing. Because the material master and stock are shared with MM, the buy side and sell side stay consistent - the same material that MM receives is what SD sells. Keeping this data governed is, as across SAP, the biggest lever on reliability.
How SD Integrates
SD is tightly linked to the rest of S/4HANA: it draws on MM for material and stock and triggers goods issue on delivery; it posts to FICO at billing, creating the receivable and recognising revenue; and it works with EWM for warehouse picking and shipping. Because billing posts straight to finance, SD and FICO have to be configured consistently or revenue and receivables go wrong. Acqurio Tech provides ongoing S/4HANA AMS for a pharmacy business across MM, SD, FICO, QM and EWM.

Frequently asked questions
What is SAP SD?
SAP SD (Sales and Distribution) is the S/4HANA module that runs the sell side of the business - capturing sales orders, determining prices, checking credit and availability, organising deliveries and shipping, and billing customers. It carries a customer order through to the invoice and the receivable in finance, a process known as order-to-cash, and it owns the sales master data and pricing rules behind those transactions.
What is the order-to-cash process in SAP SD?
Order-to-cash (O2C) is the core SD flow: optional inquiry and quotation pre-sales steps, then a sales order with pricing, credit and availability checks, then delivery (picking, packing and goods issue, which reduces inventory), then billing, which posts the invoice, revenue and receivable to finance. Each step hands off cleanly to the next, and billing is where SD connects to FICO.
How does pricing work in SAP SD?
Pricing in SD uses the condition technique - a flexible framework of condition types for base price, discounts, surcharges, freight and tax - so the correct price is calculated automatically from the customer, material and condition records. This lets you model complex pricing (customer-specific prices, volume discounts, promotions) without hard-coding, but it needs careful configuration, because pricing errors show up directly as wrong invoices.
How does SAP SD integrate with other modules?
SD draws on MM for the shared material master and stock and triggers goods issue on delivery, posts to FICO at billing to create the receivable and recognise revenue, and works with EWM for warehouse picking and shipping. Because billing posts straight to finance, SD and FICO must be configured consistently, or revenue and receivables will be wrong - which is why the SD-FICO integration deserves particular care.
Can an outsourced team support SAP SD?
Yes. Many businesses add senior SAP SD consultants through staff augmentation or an AMS arrangement to configure and support order-to-cash, pricing and credit management, with time-zone overlap so issues are handled during the working day. You keep full IP ownership and controlled change. Acqurio Tech provides this across MM, SD, FICO, QM and EWM, including GxP-aligned change for regulated businesses.
