Ten Spain delivery locations, but not ten Spain headquarters
Every company on this page carries at least one delivery location recorded in Spain, and that field alone decides membership on this page. Headquarters is a separate field, and for this composition it does not line up one to one with delivery. Of the 10 companies, 7 also record a headquarters in Spain. The other 3 are headquartered elsewhere: Luxe Quality and GlobalStep in the United States, and TSOFT in Argentina. For these three, the entity recorded as registered sits outside Spain while a Spain delivery location is recorded all the same. The delivery location field holds countries rather than cities, so no profile on this page says where inside Spain the work sits.
One tag reaches everyone, then a narrower nearshore split
All 10 companies on this page carry the Nearshore for the EU tag, so it does not separate any company from another here. A narrower tag, Nearshore for the USA, applies to 4 of the 10: GlobalStep, Internet Security Auditors, MTP and TSOFT. Each of these four also carries Nearshore for the EU, since the wider tag reaches every company in this composition. For 4 of the 10, Nearshore for the EU is the only applicability tag tracked on this page: Redsauce, S21sec, Tarlogic Security and Zerolynx carry no other tag in this composition.
Two single-company tags that never overlap
Two tags on this page apply to exactly 1 company each, and to a different company in each case. Accessibility specialists applies only to ILUNION Accesibilidad. Automation first applies only to Luxe Quality. Neither of these two companies carries the other's tag. Neither carries the Nearshore for the USA tag either.
Where these ten profiles are thinnest, and where they hold up best
None of the 10 companies on this page has a signed BAA or a GDPR data processing agreement recorded in its profile, the largest gap among the fields tracked in this composition summary. Named clients sit at the other end: 5 of the 10 profiles record at least one named client, a smaller gap than any other field tracked here. A verified certificate is recorded for 3 of the 10 profiles; the field carries no confirmed value for the other 7. A case study is recorded for 2 of the 10 profiles. An external review count from a named platform is recorded for only 1 of the 10; the other 9 carry no published value for that field. None of these fields is part of the criterion for this page: a company qualifies by its Spain delivery location alone, regardless of how many of these fields its profile fills in.
How this ranking was put together
Membership is computed from the profile, not chosen: companies appear here when they have a delivery location in one of the countries Spain covers, as their own profile states. Position in a ranking cannot be bought. Paid options are limited to the extended profile, labelled sponsor slots and lead forms, and none of them affect tags or order.
The table compares the fields that decide this axis: delivery locations, published rates, team size, plus the number of verified reviews on external platforms. Rates, minimum project size and onboarding time carry the source they came from next to the value.
- Nearshore for the EU: At least one delivery location in the EU or the EEA, or in Ukraine, Georgia, Serbia or Moldova.
- Nearshore for the USA: At least one delivery location in Canada, Mexico, Central America or South America.
- Accessibility specialists: Accessibility testing is offered as a service, and at least one published case study reports an accessibility conformance metric.
- Automation first: Test automation is offered as a service, and at least one published case study reports a coverage or regression time metric.
The criteria for this axis are on the methodology page, together with field definitions and the rule for editorial order. Changes of order are recorded in the changelog.
Questions
- How many companies on this page have at least one served industry recorded in their profile?
- 4 of the 10 companies on this page have at least one served industry recorded in their profile. The other 6 have no industry value published, so this page cannot say which sectors, if any, those 6 companies focus on. An industry value on a profile applies to the company as a whole; it does not indicate whether work in a recorded industry was carried out specifically through the Spain site.
- Does a Spain delivery location indicate that the team assigned to a project can test in Spanish and support localization work aimed at Latin American markets?
- Spanish is the official language in Spain and also the majority language across most of Latin America, so a delivery location there sits inside a language footprint that spans both regions in a way a single-language European delivery location cannot. That geographic fact says nothing about a specific team's working language: a delivery-location field records the country where a company runs work; it does not record which languages that team tests or reports in. A buyer whose project depends on Spanish-language test scripts or on localization aimed at a Latin American market needs to confirm the working language directly with the company.
- How does a Spain delivery location affect real-time overlap with a buyer's team based in the United States compared with one based elsewhere in Europe?
- Spain runs on Central European Time, a zone shared with most of continental Europe despite the country's geographic position further west, so a delivery location there keeps close to a full working-day overlap with a buyer's team elsewhere in Europe. Against a buyer's team in the United States, the same delivery location runs roughly six hours ahead of the US Eastern zone and about nine hours ahead of the US Pacific zone. The delivery-location field does not capture which working hours a specific team keeps, so actual overlap on a given engagement depends on the schedule the vendor sets for its Spain-based staff.
- Is delivering from Spain typically cheaper or costlier than delivering from another EU country?
- A Spain delivery location alone does not fix whether delivery costs more or less than sourcing from another EU country; the rate a specific vendor sets decides that, and rates vary company by company regardless of country. Only one company with a Spain delivery location on this page publishes an hourly rate, a blended figure of 25 to 49 US dollars per hour that is not broken out by seniority grade. A cost comparison against other EU countries is not something a single published rate figure can settle, and the field carries no second entry from a Spain-based vendor to compare it with.

Every fact about a company comes from a listed source. A field without a source stays empty. A certificate counts as confirmed only when a registry, certificate or auditor report backs it; a certificate the company only claims about itself is published separately, under that label. Vendors can request a correction at hello@qa-rating.com. A correction is applied when it comes with a public source.
