[View Digital Ecosystems โ†’](/en/digital-ecosystems/) ## Frequently Asked Questions Shopify or WooCommerce โ€” which should I choose? โ€บ It depends on your case. Shopify is ideal for those who want to get started quickly with less technical complexity and do not need deep ERP integrations. WooCommerce offers full control, is more flexible for advanced customisations and integrates natively with systems like Primavera, PHC or SAP. For most of our clients in Portugal, we recommend WooCommerce for its integration freedom and absence of sales commissions. I already have an online store โ€” can you migrate without losing data? โ€บ Yes. We perform full migrations from platforms such as Shopify, Magento, PrestaShop or custom stores. We migrate products, customers, order history, reviews and URLs (with 301 redirects to preserve SEO). The process is planned to minimise downtime โ€” typically the transition happens within a window of just a few hours. What payment methods work in Portugal? โ€บ We integrate all payment methods relevant to the Portuguese market: MB Way, Multibanco reference, credit/debit card (via Stripe or SIBS), PayPal, and bank transfer. For international stores, we also add Apple Pay, Google Pay and local methods from other European markets. Certified invoicing is issued automatically via integration with your billing software. How does inventory synchronisation with my ERP work? โ€บ Synchronisation is bidirectional and in real time. When a product is sold in the online store, inventory updates automatically in the ERP (and vice versa). This includes variants, multiple warehouses and inventory reservations. We integrate with Primavera, PHC, SAP, Moloni and others โ€” eliminating sales of out-of-stock products and manual counts. ## What Our Clients Say Real results. Real names. No fine print. BC Beatriz C. Fashion Brand Founder, Porto โ˜…โ˜…โ˜…โ˜…โ˜… "The new store converted at 3.2% in the first month โ€” the previous one barely reached 0.8%. With the optimised checkout and abandoned cart emails, we recovered โ‚ฌ4,200 in lost sales in the first quarter alone." NR Nuno R. Gourmet Store Owner, Lisbon โ˜…โ˜…โ˜…โ˜…โ˜… "We went from 40 orders per month to over 180 in 6 months. The ERP integration eliminated 3 hours of daily manual work and inventory errors are gone. International sales now account for 35% of revenue." JA Jorge A. B2B Sales Director, Leiria โ˜…โ˜…โ˜…โ˜…โ˜… "The B2B store with per-customer pricing and recurring orders transformed our business. Clients place orders 24/7 without calling the sales team. Visitor-to-customer conversion rate rose 127% and the average order value increased by 22%." CM Catarina M. Supplements Store Founder, Aveiro โ˜…โ˜…โ˜…โ˜…โ˜… "The subscription model changed everything. 38% of customers signed up for monthly recurring delivery โ€” predictable revenue and very low churn. CAC paid back on the 2nd purchase instead of the 5th. In 8 months we went from โ‚ฌ12k to โ‚ฌ58k MRR from the online store alone โ€” no new ad spend."
