If your business still handles purchase orders (POs) on spreadsheets, you’re losing time, control and auditability. Free purchase order software can be the perfect low-risk way to automate PO creation, approvals and tracking — giving small teams enterprise-grade discipline without the upfront cost. In this guide you’ll learn what PO software does, which free options are worth testing in 2025, how to pick the right tool for your IT environment, and practical steps to deploy it successfully.
What is purchase order software? (quick primer)
A purchase order (PO) is the buyer’s formal document sent to a supplier describing products, quantities and agreed prices — effectively the buyer’s contract for the purchase. Purchase order software digitises that process: generating POs, routing approvals, tracking receipts and (often) matching invoices for payment. This reduces manual errors and creates an auditable trail. (Corporate Finance Institute)
Why switch from spreadsheets to PO automation?
Well-implemented PO systems deliver measurable benefits:
- Reduce manual errors and duplicate orders — automated forms and validation stop common human mistakes.
- Faster approvals and visibility — approval workflows speed processing and let managers see outstanding commitments.
- Better budget control — POs give early visibility into committed spend so finance can manage cash flow and project budgets.
- Improved audit readiness — an electronic PO trail simplifies supplier audits and tax/record-keeping.
If automation is part of a broader purchase-to-pay (P2P) or procurement transformation, the efficiency gains can be much larger — P2P systems can automate requisition-to-payment steps and improve cash flow management. (Investopedia)
Who should consider free purchase order software?
Free PO tools are ideal when you need to:
- Validate a new digital procurement workflow before committing budget.
- Support small teams with low monthly PO volume.
- Trial supplier integrations or test invoice-matching workflows.
- Provide a lightweight PO system for specific projects or departments.
Free options usually trade advanced features (ERP integrations, deep analytics, multi-entity accounting) for zero cost — but they’re excellent pilots.
Top free purchase order tools & what to expect in 2025
There are many free and freemium purchasing/procurement tools available. Market aggregators and software marketplaces maintain up-to-date catalogues of free purchasing tools and free tiers to try before you buy. If you need a central place to evaluate many options, G2 lists free purchasing software and user reviews that help shortlist candidates. (G2)
Smaller specialist projects (like the Free-Procurement / Free-PO initiatives) also publish free open offerings for basic PO automation and can be especially useful for very small teams. (The Free-Procurement Project)
Quick comparison table — Free vs Paid PO software (high-level)
Capability / Need | Free PO tools (typical) | Paid / Enterprise PO software (typical) |
PO creation & templating | ✔ Basic templates, manual entry | ✔ Advanced templates, multi-currency, line-level rules |
Approvals / workflows | ✔ Single / simple workflows | ✔ Multi-stage, delegated, conditional workflows |
Invoice matching (3-way) | ✖ Often limited | ✔ Automated 2/3-way match, exceptions handling |
Integrations (ERP/Accounting) | ✖ Limited or manual export | ✔ Native integrations (Xero, QuickBooks, SAP, Dynamics) |
Reporting & analytics | ✖ Basic export | ✔ Real-time dashboards, spend analytics |
User seats | ✔ Often limited free seats | ✔ Scalable, role based access |
Support & SLAs | ✖ Community / docs | ✔ SLA, onboarding & dedicated support |
How to evaluate a free PO solution — checklist
Before you deploy, measure a candidate tool against these practical criteria:
- Core PO features: Can it create POs, capture supplier info, and generate printable PDF POs?
- Approval workflow: Does it allow at least one approval layer and email/Slack notifications?
- Export & accounting compatibility: Can you export POs in CSV or integrate with your accounting system?
- User and role controls: Does it let you restrict who can issue POs vs who can only propose requisitions?
- Audit trail & attachments: Can users attach invoices, quotes or delivery notes to POs?
- Data ownership & exportability: Are your records easily exportable so you can migrate later?
- Security & hosting: Is the tool cloud-hosted with basic security practices (HTTPS, access controls)?
- Upgrade path: If your needs grow, can you move to a paid tier or migrate to an ERP seamlessly?
Use this checklist as a lightweight RFP when trialling free tools.
Implementation best practices (IT & procurement aligned)
Because Code Hyper One helps Sydney businesses with Microsoft 365 and process automation, these implementation tips are tailored to IT teams that will deploy or secure a PO tool:
- Start with one department. Pilot POs for one team (e.g., IT or Facilities) to limit risk.
- Map current process first. Document steps, approvals and required fields so you don’t automate bad workflows.
- Integrate with existing accounts. Export formats or lightweight integrations (CSV, Teams notifications or SharePoint storage) reduce duplicate work. (SharePoint + Power Automate can be a low-cost path for customised workflows.) (Code Hyper One)
- Enforce approval rules in the tool, not outside. Avoid separate email approvals that weaken the audit trail.
- Train approvers on thresholds. Make thresholds explicit (e.g., purchases under $1,000 single approver; above $1,000 manager required).
- Plan data export and backup. Ensure you can export POs periodically and store them in your accounting system or SharePoint for long-term records.
- Review security posture. Confirm vendor security basics (TLS, access logging, account management). If you need help mapping this to Microsoft 365 governance or wider IT policy, reach out to an IT consultancy. (See how Code Hyper One helps with SharePoint automation and Microsoft 365 governance.)
When a free tool is not enough
Free tools are for pilots and small teams. Move to a paid or ERP-integrated PO solution if you need:
- Multi-entity accounting and consolidated reporting.
- Automated invoice matching and supplier reconciliation.
- Advanced approvals with delegated authority matrices.
- Procurement analytics and supplier performance dashboards.
- High-security, enterprise SLAs, or on-premise deployments.
Market research and reviews show that paid P2P platforms (or ERP modules) are focused on integration and scale — features most free tiers do not include.

- Small but flexible platforms: Platform blogs and roundups (Jotform, Spendflo, Growrk) list approachable tools with free tiers and workflow builders worth testing.
How Code Hyper One can help
If you want to run a pilot, integrate a free PO tool with Microsoft 365 (SharePoint, Power Automate, Teams) or evaluate upgrade paths into ERPs like Dynamics 365, our IT consultancy and Microsoft 365 services can help scope, secure and automate your purchasing process.

Conclusion
Free purchase order software is a pragmatic way to remove manual PO friction, tighten approvals and create an auditable trail — with minimal budget risk. Use a pilot approach, validate critical integrations (export to accounting, notification channels), and prioritise data exportability so you’re never locked in. When requirements scale — advanced matching, analytics and ERP integration — a paid P2P or ERP procurement module becomes the right choice. Start small, measure impact, and iterate.
Frequently Asked Questions
What exactly is a purchase order and why does it matter?
A purchase order (PO) is the buyer’s formal instruction to a supplier describing the items, quantities and agreed prices. It matters because it creates a legally defensible record of the order, improves budget control and simplifies audits. (Corporate Finance Institute)
Can free purchase order software handle invoice matching?
Most free tools offer basic matching or manual reconciliation. Automated 2- or 3-way matching (PO vs goods receipt vs invoice) is usually a paid feature in enterprise P2P systems. If invoice matching is essential, evaluate paid upgrades or ERP options. (AvidXchange, Spendflo)
How do I choose between a free tool and upgrading to a paid P2P system?
Use free tools to pilot processes, then upgrade when you need advanced integrations (ERP/accounting), automated invoice matching, multi-entity support, or enterprise analytics. Track the operational cost of manual work during the pilot — when that cost exceeds the paid tier, it’s time to scale. (Investopedia, G2)
