Free Purchase Order Software (2026): 8 Free Plans Compared

Which purchase order software tools have a free plan in 2026?

Every tool below lets you produce a purchase order at no licence cost with no end date; the difference is how much of the purchasing process it covers. Odoo, Dolibarr and ERPNext cover RFQ, PO, receipt and supplier bill. Zoho Inventory, Zoho Books, Wave and Invoice Ninja are inventory or accounting tools whose free tiers handle bills and vendor records; Zoho Books says outright that POs start at Professional, and the other three do not mention POs on their pricing pages at all. Vertex42 is a template.

What is missing is the entire procurement-software category: Procurify, Precoro, Coupa, Kissflow, Bellwether and Order.co quote or demo only; Tradogram ($99 a month), Spendwise ($9 a user) and ProcurementExpress ($415 a month) sell trials. If you need approval routing in a hosted tool without hosting anything, there is no free option — Odoo is the nearest and its Purchase app page does not mention approvals.

The table shows what each free tier states about POs, the binding cap and the Free Score. Open a row for users, licence, the upgrade trigger and the page we checked.

Why it ranks here. The only hosted free tier here built for purchasing, with no seat cap. The one-app rule is the catch: the moment you want Inventory beside it, every user is $31 a month.

Why it ranks here. More ERP than Dolibarr and more to run; the $5 managed option is the cheapest hosted ERP on Kurums Free, but it is not free.

Why it ranks here. A form, not a system; honest and free, and the right answer for a company that raises three POs a year.

Which free PO tool has no credit-card requirement?

Odoo states no card on its Purchase app page; Dolibarr, ERPNext (self-hosted) and the Vertex42 template need nothing. Zoho Inventory, Zoho Books, Invoice Ninja and Wave do not state it. Nothing here auto-converts; Zoho Inventory’s trial drops to the free plan.

The procurement platforms that do take a card are the excluded ones — ProcurementExpress’ trial needs none but ends in 14 days; Tradogram and Spendwise sell from the first month.

When does the free plan stop being enough?

Kurums Match: which free PO tool fits your situation?

How did we verify these free tiers?

We opened each vendor’s pricing page and, for open-source projects, the official repository, and recorded PO features, user and order caps, licence and the paid step. Zoho Inventory’s pricing page does not state PO availability on its free plan, so it is marked not stated. Invoice Ninja’s repository shows the Elastic License, which is source-available rather than OSI open source, and its pricing page does not mention POs. Procurify, Kissflow, Coupa, Bellwether and Order.co were excluded as quote-only; Tradogram, Spendwise, ProcurementExpress and Precoro as paid or trial-only.

Prices are USD.
