Irish Compliance Comparison

For Irish businesses, compliance with Revenue, GDPR, and local banking standards is non-negotiable. Here is how ResDiary and SumUp POS compare on the requirements that matter most to Irish SMEs.

Revenue Integration

Neither ResDiary nor SumUp POS offers native Revenue Online Service integration. Irish businesses in crm may not need this feature directly, but should ensure their accounting software handles Revenue compliance separately.

Irish Bank Feeds

Neither ResDiary nor SumUp POS offers direct Irish bank feed integrations, which is expected for crm software. Your accounting platform should handle bank feeds separately.

GDPR Data Residency

Both ResDiary and SumUp POS store data in EU data centres, providing strong GDPR compliance out of the box. Irish businesses can use either platform without worrying about cross-border data transfers to the US or other non-EU jurisdictions.

SEPA and IBAN Support

SumUp POS supports SEPA Direct Debit and Irish IBAN format, making euro payments and bank transfers seamless. ResDiary does not support SEPA natively, which could mean extra manual steps when processing euro payments or setting up direct debits for Irish customers.

VAT Handling

Neither ResDiary nor SumUp POS handles Irish VAT directly. This is expected for crm tools - your accounting software should manage VAT compliance.

Who Should Choose ResDiary

ResDiary is the better fit if your business matches one or more of these profiles:

✓ Growing businesses with 21-50 employees that need a platform which scales
✓ Those who value: purpose-built for restaurant reservations
✓ Those who value: strong google reserve and direct booking integration

Who Should Choose SumUp POS

SumUp POS is the better fit if your business matches one or more of these profiles:

✓ Those who value: no monthly subscription fee
✓ Those who value: irish iban payouts supported
✓ Those who value: very simple to set up

Our Verdict

ResDiary is the clear choice for Irish restaurants, hotels, and hospitality groups that manage advance bookings, table allocation, and guest communications - its purpose-built reservation engine, Google Reserve integration, and deposit handling address needs that SumUp POS simply does not cover. SumUp POS wins for Irish sole traders, market traders, and micro-businesses in retail or hospitality that need a low-cost way to accept card payments with no monthly subscription, supported by Irish IBAN payouts via SEPA, making settlement straightforward for Irish business accounts. Neither vendor offers native Revenue integration or PAYE Modernisation connectivity, so Irish businesses using either platform will need separate payroll and accounting software.

ResDiary suits businesses with 1 to 50 employees in hospitality, while SumUp POS is realistically best for businesses with 1 to 5 employees given its limited advanced POS features and basic reporting. Both vendors process data within the EU, satisfying GDPR data residency requirements, and both offer Irish-based support.

Ultimately, the best choice depends on your specific business needs, team size, and priorities. We recommend taking advantage of free trials from both vendors before making your final decision. If you are working with an Irish accountant or payroll bureau, ask which platform they prefer - their familiarity with the software can save you significant time and hassle during setup and ongoing support.
