What to Look For in Irish T&S Software

If you're evaluating travel and subsistence expense software for an Irish business, the features that matter most aren't the ones in the marketing headlines — they're the Irish-specific compliance details that a generic, global expense tool quietly gets wrong. This is a neutral checklist of the evaluation criteria that actually matter, framed as questions you can put to any vendor. No product is named or knocked; the Irish-specificity speaks for itself.

Why "Irish-Specific" Is the Real Test

Most expense tools can photograph a receipt and route an approval. Where they differ — and where the compliance risk lives — is whether they understand Irish Revenue rules: the progressive civil service mileage bands, the subsistence eligibility tests, the normal-place-of-work distinction, and Enhanced Reporting Requirements. A tool that applies a single flat mileage rate, or a UK/US rate set, will produce claims that are wrong at source.

Use the checklist below as objective evaluation criteria. For each one, there's why it matters and a question to ask the vendor. Score every product you're considering against the same list — including this one.

The Evaluation Checklist

1. Irish rate accuracy

Why it matters: The whole point is correct, tax-free reimbursement. The tool must use the current civil service mileage and subsistence rates — not UK HMRC rates, not a generic flat rate.

Ask the vendor: Which rates does it use, and are they the current Irish civil service rates? How quickly are they updated when Revenue changes them?

2. Cumulative-band handling

Why it matters: Irish mileage uses four progressive bands based on each employee's year-to-date distance. A trip can cross a band mid-claim. Flat-rate tools get this wrong all year.

Ask the vendor: Does it track distance per employee across the year and split a trip that crosses a band boundary automatically?

3. Subsistence & journey rules

Why it matters: Day vs overnight rates, the duration and distance tests, the "lesser of" rule, and normal-place-of-work handling all determine what's claimable. Foreign trips use per-country rates in local currency.

Ask the vendor: Does it apply the subsistence eligibility tests, the lesser-of rule, and foreign subsistence in the correct currency?

4. ERR export

Why it matters: Since 1 January 2024, reimbursed T&S must be reported to Revenue via ROS on or before payment. This is now a routine obligation, not a year-end task.

Ask the vendor: Does it produce a categorised, ROS-ready ERR export, and does it support the on-or-before-payment timing?

5. Approval workflow

Why it matters: Public bodies and good governance need a clear sign-off chain with segregation of duties — no one approving their own claim.

Ask the vendor: Can it model multi-tier approval, and does it prevent self-approval?

6. Free accountant access

Why it matters: Your accountant or bookkeeper often manages filings and year-end. Access without an extra per-seat charge removes real friction.

Ask the vendor: Can my accountant get access, and is it included or charged per seat?

7. Audit trail & retention

Why it matters: You must keep records for six years and be able to produce any single claim — trip, rate, approval, payment, ERR submission — if Revenue asks.

Ask the vendor: Is there a complete, time-stamped audit trail, and are records retained and retrievable for the full period?

8. Data residency & GDPR

Why it matters: Expense data is personal data (names, addresses, journeys, bank details). Where it's stored and processed matters — essential for public-sector buyers.

Ask the vendor: Where is the data stored and processed? Is it within the EU/EEA, and is a GDPR data processing agreement available?

9. Practical fit

Why it matters: It has to be used. Fast mobile logging, receipt capture, clean reporting/exports, transparent pricing, and responsive support decide whether a tool actually sticks.

Ask the vendor: Can staff log trips from a phone? Are exports (PDF/CSV) clean? Is pricing transparent with no surprise add-ons?

The underlying rules behind these criteria are worth understanding before you buy: the civil service rates, normal place of work, ERR, and the full compliance checklist. A vendor who can talk fluently about these is a good sign.
