Process Mapping for Small Businesses: Order-to-Cash and Procure-to-Pay

Two cycles run through almost every business: order-to-cash, from customer order to money in the bank, and procure-to-pay, from need to vendor payment. Mapping them visually is one of the fastest ways to find delays, revenue leakage and control gaps.

What a Process Map Shows

A process map shows each step, who performs it, which system is used, what document is created, and where decisions or approvals happen. Swimlane maps, with a lane for each team, work well for cross-team processes.

Order-to-Cash

1. Customer order or contract received.
2. Credit check and approval.
3. Order entered in the system.
4. Goods dispatched or services delivered.
5. Invoice raised, with e-invoice IRN where applicable.
6. Payment received and matched.
7. Overdue accounts followed up.

Common risks: delivery without invoicing, pricing errors, unauthorised discounts, credit notes without approval, and slow collections.

Procure-to-Pay

1. Purchase requisition raised.
2. Vendor selected and purchase order approved.
3. Goods or services received and recorded.
4. Vendor invoice received and matched to PO and receipt.
5. TDS deducted where applicable.
6. Payment approved and released.

Common risks: fictitious vendors, duplicate payments, paying for goods not received, missed TDS, and input tax credit lost because vendors didn't file.

How to Map

• Walk through the process with the people who do it, not just managers.
• Map what actually happens, including workarounds.
• Mark handoffs, delays and manual steps.
• Mark where controls exist, and where they're missing.

Using the Map

Once mapped, look for steps that can be removed, automated or combined, and for risks without controls. The map then becomes the backbone of SOPs and internal controls documentation.
