What Is A Purchase Order (PO)?

A purchase order (PO) is a formal document a buyer sends to a supplier to confirm a purchase. It clearly outlines what’s being bought, the quantity, agreed price, delivery timeline, and payment terms. Think of it as a contract that protects both sides ensuring there’s no confusion about expectations. POs also create a reliable paper trail, which makes audits easier and helps finance teams track spending against budgets.

‍

For modern businesses, POs aren’t just paperwork; they’re an essential tool for cost control and compliance. Instead of chasing down scattered requests or unclear invoices, POs give you visibility into every purchase. And when managed through platforms like Spendflo, the process is automated from creation to approval to reconciliation, saving time, reducing errors, and giving finance leaders more control over SaaS and vendor spend.

‍

What is PO automation?

Purchase Order (PO) automation is the use of software often enhanced by AI to create, approve, send, and track purchase orders digitally. Instead of relying on paper forms, spreadsheets, or scattered emails, businesses manage the entire PO process in one centralized platform. This makes procurement faster, more accurate, and easier to control.

‍

According to the 2023 Benchmarking Report on Automation Trends by the Institute of Finance & Management (IOFM), more companies are turning to automation to improve efficiency in core processes like PO management.

‍

Purchasing Made Digital

Think of it like online shopping. Instead of writing down what you need and mailing it to a store, you just select the items, click a button, and it’s done. PO automation works the same way employees submit requests, the system generates POs, and suppliers receive them instantly.

‍

Streamlined Ordering

With PO automation, businesses can digitally specify what they want to buy, in what quantity, and at what price. The system routes the request for approval, generates a PO, and sends it directly to the supplier. This eliminates manual errors and speeds up procurement.

‍

Faster Approval & Payment

Once goods or services are delivered, the software matches the supplier invoice against the PO and receipt. If everything aligns, approval and payment can happen automatically. This not only strengthens supplier relationships but also ensures finance teams close books on time.

‍

Importance of PO Automation

Automating purchase orders changes the way procurement and finance teams work. Instead of chasing emails or fixing errors in manual entries, automation delivers a faster, more reliable process. Approvals move smoothly, records stay accurate, and finance teams close books on time freeing up bandwidth for more strategic priorities.

‍

Key Benefits of PO Automation

• Efficiency: Cuts down manual work, speeds up approvals, and reduces human error.
• Compliance: Creates a complete audit trail and enforces policy checks automatically.
• Supplier Relations: Ensures timely, accurate POs and payments, strengthening trust.‍
• Cost Control: Flags overspending early and provides visibility into budgets and vendor contracts.

How does an ineffective PO process affect your bottom line?

Worryingly, 67% of supply chain managers still use Excel to manage aspects of their supply chain. Such an inadequate PO process can hurt your company's bottom line in several ways. Here's how:

‍

• Increased errors: Mistakes such as over-ordering or under-ordering become more common, leading to financial waste or shortages that disrupt operations.
• Wasted time: Employees spend too much time handling paperwork or correcting issues, diverting attention from more productive tasks.
• Project delays: Incorrect or late orders can postpone projects, upset customers, and potentially increase costs to expedite completion.
• Overspending: A lack of a tracking system for purchases and spending can result in going over budget. This might happen because more inventory visibility is needed to secure the best prices or because unnecessary items are bought.
• Strained supplier relationships: Suppliers prefer reliable partners. A chaotic PO process can cause frustrations like late payments or order inaccuracies, potentially  harming future negotiations or deals.
• Legal and compliance risks: Disorganization in the PO process can lead to regulatory non-compliance or legal issues, entailing hefty fines and reputational damage.
• Loss of trust: Frequent errors and inefficiencies can erode trust among employees, customers, and partners, leading to lost sales and damaged relationships.
  ‍

Manual PO process challenges & How automation fixes them

Manual purchase order (PO) processes slow down procurement, increase costs, and create compliance risks. In fact, a 2023 Deloitte survey found that companies using manual procurement workflows spend up to 30% more time on administrative tasks compared to those with automation. Here are the most common challenges and how automation addresses them.
