Seia
The office is in the Serra da Estrela.
27n has bases in Seia, Évora and Lisbon.
The problem
Selling online and running the company are the same problem.
A slow store loses sales. A disconnected ERP, invoicing on the side and paper documents stall the operation. We build the store and what connects it to the rest of the business.

FAQ
Questions brands usually ask before starting.
How much does a Shopify project cost?
It depends on scope: custom theme, migrations, integrations and Plus features change the budget. After a discovery call we send a fixed proposal in 48–72h, no retainers required to get a clear number.
How long does a store take to launch?
A focused custom build typically lands in 6–10 weeks. Migrations with ERP integrations or multi-market setups can take longer. You get a roadmap with milestones from day one.
Can you migrate from WooCommerce, Magento, Wix, VTEX and others?
Yes. We migrate from Square, WooCommerce, Etsy, Wix, Amazon, eBay, Clover, Lightspeed R/X (Vend), Magento, Adobe Commerce, VTEX, PrestaShop, nopCommerce, Jumpseller, Weasy, BigCommerce, Ecwid, Joomla + VirtueMart, OpenCart and Squarespace, with 301 redirects URL by URL.
Do I need Shopify Plus?
Plus makes sense at higher volume or when you need checkout extensibility, B2B, advanced automation or expansion stores. We'll help you decide without upselling more than you need.
What happens after launch?
Launch is the start. Most clients stay with us for support, CRO and continuous improvement. We can also train your team to manage day-to-day catalog and content.
Do you only work with Shopify?
No. We have been a Shopify Select Partner since 2021 and we also build websites, Astro and Medusa stores, AT-certified invoicing (SAF-T, ATCUD, QR code), MB WAY and Multibanco payments, ERP integrations (Moloni, Primavera, Sage, Zone Soft), custom software, cloud, cybersecurity and digital preservation.
