Square Appointments is one of the most polished tools in the world for managing bookings - but it's a North American tool. The Square ecosystem integrates card terminal, e-commerce, payroll, capital - it's mature and impressive. Outside the US/UK, however, there are barriers that change everything: the Square terminal isn't officially available in many countries, invoices don't comply with most local tax rules, and language support is uneven. This comparison goes into the details.
Where Square is genuinely strong
Square strengths (in the right markets)
- Integrated ecosystem: bookings, terminal, e-commerce, payroll, capital - all in one account.
- Own hardware (Square Reader, Square Stand) well designed.
- Mature mobile app with 10+ years of iteration.
- Huge marketplace of plugins and integrations.
- Strong presence and support in the US, UK, Ireland.
Limitations outside the US/UK
- Square Reader isn't homologated by most non-US/UK banking authorities.
- Local fiscal invoicing (tax ID, informational fiscal codes, correct VAT) isn't native.
- Chat support in Portuguese is limited, with long waits.
- Setup designed for the American market - some fields confusing for non-US users.
- No WhatsApp as a native channel - you depend only on email/SMS.
- Onboarding requires international banking link for some features.

Catarina's case, owner of a massage space in Lisbon
Catarina tried Square for 4 months. Features: great. Everything else: pain. Tax ID invoices for insurance clients - she had to generate separately on InvoiceXpress. Portuguese support - chat closed at 5pm Portugal time. Hardware - she used her own Caixa terminal, no Square integration. In the end, the feeling was of having powerful tools poorly aligned with her reality. Migrated to BookHero in 3 hours and never looked back.
When Square still makes sense
If you operate primarily in the US/UK and want a single platform to manage everything, Square may be the right choice. If most of your billing goes to clients there, the Square ecosystem pays its complexity.
When BookHero is the obvious path
- You operate outside the US/UK.
- You need native informational invoice with tax ID.
- You want WhatsApp reminders instead of SMS.
- You value human support in Portuguese by the product team.
- You don't want to complicate with international card terminals or strange integrations.
The quick choice
Business outside the US/UK? BookHero - the tool plays well with your local fiscal rules and language. Operating primarily in the US/UK? Square may pay its complexity. If you're fighting Square's American defaults daily, migrate.
