Questions, answered properly.

An authorised software licensing distributor — founded in Hong Kong in 2011, headquartered in Singapore since 2019, operating globally. We serve individuals, IT professionals, and resellers with genuine licenses, a free public knowledge base, and support that stays past the sale.

Since 2011 — fifteen years of software licensing, through two jurisdictions and one very hard year (2019, when we relocated the company to Singapore). The full story is on our About page.

Yes — registered in the Microsoft Partner Network, ID 7033487. Microsoft products in our catalogue carry that status; documentation is available whenever procurement asks.

No. Arco is a licensing distributor: genuine keys and activation support. We don't provide infrastructure migration, deployment consulting, or application compatibility services — and we say so up front rather than disappointing you later.

Yes — three tiers (Reseller, Preferred Partner, Strategic Partner) with wholesale rates, scaling terms, and dedicated support. Details and the application live on the Partner page.

Yes. One-off volume purchases are quoted individually — write to us with the products and quantities, and you'll get a wholesale-informed price without any partner commitment.

On partner tiers, yes: Net 14 at Preferred and Net 30 at Strategic, defined in your partner agreement. First-time and Reseller-tier orders are pre-payment.

We encourage it. Buy one retail key, run it through your own process end to end — delivery, invoice, activation — then apply for partnership. There is no minimum first order.

Under 3 minutes, by email — your key, your VAT invoice, and the installation guide for the exact product you bought. Delivery is automated, so it's just as fast at midnight as at noon.

Yes — every order, automatically, attached to the delivery email. Suitable for business accounting and procurement documentation.

Yes. Our licenses are used by home users, businesses, and IT providers alike; where a product carries a usage restriction, it's stated plainly on the product page before you buy.

Activation is guaranteed. If a key fails within its warranty, we replace it first — quickly, without argument. If a genuine problem can't be fixed, refunds follow our Return Policy — write to us and we sort it. Either way, you're not left holding a dead key.

Email or WhatsApp, 7 days a week, 8:00–21:00 CET, same-day response. All channels are on the Support page.

Both exist — and we label them unmistakably. Perpetual licenses (e.g. Windows, Office Pro Plus) are one-time purchases, yours permanently. Subscription products (e.g. Microsoft 365, most antivirus) renew on a stated term. The product page always says which.

Retail keys are the most flexible — they survive reinstalls and can move to a new machine. OEM keys bind to the first hardware they activate on. Bind licenses attach to a Microsoft account rather than a key. Every product states its type before checkout, and the Library explains each in depth.

Stated on every product page — most retail licenses cover one device at a time, while multi-device editions say exactly how many. If you move machines, the license moves with you (the guide is in the Library).

Retail keys survive reinstalls and formats. Changing machines is a five-minute process — deactivate, reinstall, reactivate (or phone activation for stubborn cases). We attach the exact walkthrough to your delivery email.

Your delivery email includes the official download source and a step-by-step activation guide for your exact product. If anything argues, the Library has the fix — and support answers 7 days a week.

First, the Library — most activation errors have a written fix that takes minutes. If the key itself is at fault, contact support with your order number: that's a warranty case, and we replace the key without argument.

Online activation is the default; where it refuses, phone activation (slui 4 on Windows) completes it offline via Microsoft's automated line. The Library walks you through it.

Multilanguage products, yes — install in any supported language or switch afterwards. Single-language editions say so plainly on the product page.

Every product page states its system requirements, supported platforms, and bitness. Unsure which edition your machine needs? The Library's version guides answer it in a minute — before you spend anything.

Desktop licenses are for desktop systems. Products with genuine mobile coverage (some antivirus and VPN suites) state their device types explicitly on the product page.

Generally yes for retail licenses, subject to the vendor's own terms — and where a product restricts VM or RDS use, we state it before checkout, not after.

Wherever the vendor does, yes — with a plain-words comparison of what each edition actually adds, so you buy the one you need rather than the one that sounds bigger.

Yes. Every licence is sourced through authorised distribution channels and traceable to its source. Microsoft products carry our Microsoft Partner Network status; EU digital-exhaustion law (UsedSoft v. Oracle, C-128/11) is the legal framework our trade operates under.

No. You receive a genuine key, a VAT invoice, and — on request — sourcing documentation. That's a lawful purchase with a paper trail, which is precisely what grey-market sellers cannot give you.

A VAT invoice with every order, automatically. For procurement and compliance audits, sourcing documentation is available on request — we built the business assuming someone would eventually ask.

Globally valid unless the product page states otherwise. Regional limitations, where a vendor imposes them, are declared before checkout — never discovered at activation.
