Purchase order software for Irish businesses
'Purchase order software', 'po software' and 'purchase order management system' each get around 50 searches a month in Ireland. Small numbers, but a common story: POs in a spreadsheet, invoices matched by memory, and approvals by email.
The short answer
Purchase order software for Irish businesses should raise POs from approved requests, carry the correct VAT rate or reverse charge on each line, handle euro and sterling orders, record goods receipts and match invoices before payment. It should sync with Sage 50, Xero, NetSuite or Dynamics 365 and be able to match structured EN 16931 invoices when Irish e-invoicing begins in November 2028.
What changes when Irish POs leave the spreadsheet
Irish mid-market companies often run POs from a numbered spreadsheet and a Word template. That is fine until two people take the same number, a supplier in Belfast invoices in sterling, or a delivery arrives short and nobody records it.
PO software ties each order to its approval, its currency, its VAT treatment and its delivery. When the invoice comes in, AP checks it against all four. Variances get flagged instead of paid.
Cross-border trade is the reason Irish teams feel this sooner than others. Orders to Northern Ireland, Great Britain and the EU each carry different VAT and currency rules, and getting them right on the PO saves a lot of credit notes.
What Ireland asks of a purchase order software
On an Irish PO, the VAT treatment and the currency matter most. EU supplier orders should expect reverse charge invoices with no Irish VAT. Sterling orders need an exchange rate policy. And from November 2028, large corporates will receive domestic invoices as structured data, so the PO should hold enough detail to match automatically.

Start where your team actually is
If you are replacing a spreadsheet, keep research short and test vendors with real POs from Irish, UK and EU suppliers.
Count the cost of loose POs
Duplicate orders, unmatched invoices and late approvals add up. Measure them in Ireland first.
Test the awkward cases
Ask each vendor to handle a split delivery and an amended PO from your Irish business.
Confirm fit, then sign
Get pricing in writing and agree a go-live date that avoids your Irish year-end.
Requirements to put in your Ireland purchase orders RFP
Add these Irish rows to the usual PO numbering, templates and approvals.
| Requirement | Why it matters in Ireland | Ask the vendor |
|---|---|---|
| 1VAT rate per line | Irish orders can mix rates and zero-rated goods. | Show a PO with 23%, 13.5% and zero-rated lines. |
| 2Reverse charge for EU suppliers | EU invoices arrive without Irish VAT. | Does the PO tell AP to expect a reverse charge invoice? |
| 3EUR and GBP orders | Trade with Northern Ireland and Great Britain is common. | How is the exchange rate set on a sterling PO and at invoice? |
| 4Goods receipt | Matching needs proof of delivery. | Can a warehouse user record partial receipts on a phone? |
| 5Three-way match | Matching is the payoff of using POs. | How much price or quantity variance can we allow, and where do exceptions go? |
| 6Structured invoice matching | E-invoicing begins for large corporates in November 2028. | How will EN 16931 invoices reach your matching engine? |
