TSI Outsourcing: Customer Service & Sales Experts - Santa Clarita - California

## Tri Source International (TSI Outsourcing)

Tri Source International, operating as TSI Outsourcing, is a nearshore-focused BPO headquartered in Valencia, California (Santa Clarita area), with delivery centers spanning Los Angeles, Austin, Tijuana, Mexicali, Nicaragua, Costa Rica, Panama, and the United Kingdom. The company positions itself around what it calls "Nearstaffing" -- a delivery model that blends Central American labor cost advantages with the geographic and cultural proximity of its Baja Production Triangle, a cluster of US and Mexico locations all within 3.5 hours of each other by road or air.

The practical pitch here is straightforward: you get offshore-adjacent pricing with minimal timezone friction, agents who have strong US cultural awareness, and easy executive travel to the delivery site. That combination matters most to mid-market US companies that want cost savings but cannot afford the coordination overhead of a pure offshore engagement in the Philippines or India.

### What TSI Actually Delivers

The service portfolio covers three broad areas.

**Customer Experience** is TSI's primary line. This includes omnichannel support across voice, digital, and presumably chat and email channels -- the company describes its CX delivery as always omnichannel. They explicitly reject an one-size-fits-all model, which is the right framing for a buyer who has learned that generic contact center coverage rarely lifts customer satisfaction metrics.

**Back Office Support** covers billing services through to more complex back-office tasks. TSI frames this as the operational backbone that keeps front-line agents effective. The specifics of which processes they run (claims processing, data entry, document handling) are not fully detailed in available materials, so a buyer evaluating this area should ask directly: what back-office processes have you run for a company of my size and complexity, and what does your QA workflow look like for non-voice work?

**Sales** is listed as a distinct practice. TSI describes this as needing "aggressive teammates" who can hustle and build brand equity -- that language signals outbound or blended inbound/outbound sales rather than pure order-taking. Whether this includes structured telemarketing, appointment setting, or full outbound lead generation is worth clarifying before you shortlist them for a sales engagement.

TSI has also built out a **AI Customer Service** offering, positioning AI phone agents as a complement to their human agent workforce. The capabilities listed include human-like voices, 24/7 support, compliance monitoring, multilingual handling, and data protection. The company publishes an AI Agent Fact Sheet and voice samples on their site, which is an useful starting point for a buyer evaluating whether their AI layer is a real product or just a slide in a deck. I would listen to those samples and ask what the escalation path looks like when the AI agent hits its limits -- that handoff is where most AI-in-contact-center deployments fail.

TSI also offers a **Pay for Performance** and **Value Based Care** model, suggesting they operate in outcome-adjacent commercial structures for at least some clients. The Value Based Care label typically signals healthcare-adjacent work.

### Delivery Footprint and Language Capability

The Baja Production Triangle -- Los Angeles plus Tijuana and Mexicali -- is the core delivery model. TSI highlights English proficiency across all its Mexico locations and publishes agent voice samples by name, which signals transparency around a key buyer concern for nearshore Mexico delivery. Nicaragua, Costa Rica, and Panama round out the Central American footprint.

The UK office is listed but not elaborated on. It may are a sales or account management presence rather than a delivery center -- confirm this if EMEA delivery matters to you.

Languages supported include English and multilingual capability, with Spanish almost certainly native to the Mexico and Central America sites. Confirm the specific language mix on your call if you need Portuguese, French, or other languages.

### Client Profile and Verticals

TSI serves what it describes as "leading global companies" but does not name clients publicly beyond an anonymized healthcare executive testimonial. That testimonial specifically calls out TSI's ability to recruit personnel tailored to specific needs, which points to a strength in custom hiring profiles rather than pulling from a generic agent pool. That matters if your process requires domain knowledge -- healthcare, insurance, technical support -- rather than general customer service.

The Value Based Care and healthcare executive reference suggest healthcare is a real vertical, not just an aspiration. Whether they have structured compliance workflows for HIPAA-regulated data is something a healthcare buyer must verify directly -- no certifications are publicly documented in available materials.

### Pricing and Engagement Model

TSI lists a Pay for Performance model, which implies at least some engagements are structured around outcomes. For an US buyer, nearshore Mexico and Central America rates typically land in the $10 to $22 per agent hour range depending on process complexity and dedicated versus shared staffing. I would expect TSI to sit somewhere in that band, with the Baja Triangle locations at the higher end of nearshore due to their US-proximity premium. Confirm whether pricing is per-seat, per-hour, or outcome-linked before comparing quotes.

### Editor's Take

TSI is a reasonable candidate for an US company that wants nearshore delivery, values easy site visits, and needs strong English and US cultural alignment without paying onshore rates. The Nearstaffing model is a real differentiator compared to vendors who treat nearshore as just "cheaper than the US."

The things I would pressure-test: ask to see the QA process documentation, not just the SLA number. Ask who manages the day-to-day team -- is there a dedicated team lead, and how is performance reported? If you are in a regulated industry, confirm compliance posture before assuming it is covered. The AI agent offering is worth exploring if you have high-volume, repetitive inbound queries, but get a live demo and map out the escalation logic before committing.

For a mid-market US company needing bilingual or English-only CX and back-office support with same-timezone or near-same-timezone coverage, TSI is worth a conversation. For a buyer needing deep offshore cost arbitrage or documented HIPAA/SOC 2 compliance from day one, do more homework before shortlisting.
