Frequently asked questions

Software companies usually deliver late — what guarantee do you give?

We work fixed-price + fixed-deadline. The delivery date is in contract; if we are late, we pay 3% penalty per week (max 20%). We manage this because we set a tight scope from day one, avoid scope creep and use AI-assisted code. 23 of our last 24 projects delivered on time or earlier (references shared on the call).

Do you hand over the code or do we depend on you?

**The code is 100% yours.** GitHub repo is transferred for free. You can continue with any other company or hire internal developers. Vendor lock-in is not our model — we retain clients through quality, not contracts.

You use AI — won't quality be inferior to human code?

On the contrary. Our senior with Cursor + Claude/GPT-4 delivers ~40% faster and with 25% fewer bugs than a solo developer (own measurements). AI writes code, but architecture, code review and tests go through our 12-year team. Result: same quality, faster and cheaper.

Are prices in Euros? What VAT regime?

Yes, all prices in **Euros (EUR)** + **IVA 23%** (mainland standard rate). For business clients in the Azores (16%) or Madeira (22%) we apply the regional rate. AT-certified invoicing with ATCUD and monthly SAF-T(PT). We accept SEPA transfer, card (Stripe), MB WAY and Multibanco.

Where is the hosting? GDPR compliant?

Yes — GDPR compliant by default. We recommend hosting on **OVH Portugal (Lisbon)**, **IONOS** or **Aruba** (EU datacenters). AWS Lisbon and Azure West Europe also available. Personal data stays in the EU; designated DPO; ROPA (Record of Processing Activities) delivered. CNPD audit possible at any time.

Have you built software for our sector in Portugal?

Logistics (CTT/DPD multi-warehouse), e-commerce (Worten/Fnac/Amazon ES), healthcare (SNS24/PDS), construction (Segurança Social PT), restaurants (Bolt Food/Uber Eats), real estate (Idealista/Imovirtual), B2B retail (PRIMAVERA + AT) — we have production projects in all. If your sector is not listed, on the call we present 1-2 similar clients.

Which systems do you integrate in Portugal?

**ERP/Accounting:** PRIMAVERA Professional/Executive, Sage X3 PT, Moloni, InvoiceXpress, Cegid Quadrant, Multipeers, Toconline. **AT/e-Document:** e-Fatura, ATCUD, SAF-T(PT), IES, Modelo 22, IVA return. **Marketplaces:** Worten, Fnac PT, KuantoKusta, Amazon ES, El Corte Inglés PT, Continente Online, OLX Portugal, PCDIGA. **Payments:** Stripe PT, MB WAY, Easypay, Eupago, PayPal, Multibanco. **Shipping:** CTT (Correios), Chronopost Portugal, DPD Portugal, Nacex Portugal, MRW Portugal, DHL Portugal. If the system exposes REST/SOAP API, we integrate.

Do you have an office in Portugal? Where?

Yes — **Lisbon (Avenida da Liberdade / Príncipe Real)** is the main office. We also serve clients in **Porto, Braga and Coimbra** with regular visits. In-person meetings in Lisbon by appointment; rest of the country by Google Meet/Teams. Team speaks PT-PT (not Brazilian), EN and ES.

Do I really need a mobile app or is web enough?

If you have field staff (CTT courier, store manager, site engineer, doctor) mobile is essential — push, offline, camera (QR/barcode/photo). For desktop-only teams a Progressive Web App (PWA) is enough — faster and cheaper. On the call we recommend based on the scenario; if you do not need mobile, we say so.

Custom Software for Portugal — AT-Certified by Design

Any custom business application targeting Portugal — CRM, WMS, B2B portal — must integrate AT (Autoridade Tributária) certification, the e-Fatura rail, monthly SAF-T PT exports and the ATCUD chained-sequence engine. ZunaPro ships these turn-key on NestJS, .NET 8 or Spring Boot.

PHC Software integration

PHC CS dominates Portugal's SME ERP market. ZunaPro syncs customers, products, stock, orders and invoices via PHC WebAPI, the legacy WebService and PHC FX. Same contract works for PHC dCloud hosted and on-prem SQL Server.

Primavera BSS / Cegid Primavera

Primavera BSS rules the mid-market. ZunaPro standardizes integration via the Primavera Public API, Web CRM SDK and P-Tray middleware, with dedicated mappers for each Pro / Executive / Enterprise / Elite edition.

SAGE 50 PT and ETICADATA

SAGE 50 Portugal and ETICADATA (hospitality/retail) have ZunaPro pre-built connectors. The data contract is unified: ProductFamily, VATCode, StockMovement, Invoice/ATCUD.

e-Fatura AT API

Submission to Portal e-Fatura AT uses the DGITA SOAP WebService. ZunaPro's WS Faturas API client transmits each document in real time and monitors the Comunicação de Faturas 5-business-day deadline.

SAF-T PT — automated monthly

SAF-T (PT) is the AT audit XML format. The billing SAF-T is due by the 5th of each month; the accounting SAF-T is yearly. ZunaPro produces schema-valid XML with a chained digital signature to prevent tampering.

ATCUD and QR code engine

For each invoice series ZunaPro fetches a Código de Validação from AT, stores it permanently and stamps every document as ATCUD-AAJ-XXXXX. The QR is embedded in the PDF and exposed as a base64 PNG via the API.

Multibanco reference engine

For B2B portals, ZunaPro calls SIBS WebService to mint the entidade + 9-digit referência + valor triplet with a 72-hour validity window, then listens for SIBS webhooks to mark orders paid.
