When a company decides it needs more qualified leads, the first question that comes up is almost always the same: do we hire an SDR directly or use staff augmentation?
It's a decision that seems simple but has deep implications for cost, speed of results, operational flexibility and business risk. And most companies make it without having all the data on the table.
In this article we do the complete comparison: real costs, ramp times, risks and benefits of each model so you can make the right decision for your company.
A direct hire that doesn't work out can cost between 3 and 6 times the employee's annual salary when you add up recruiting costs, onboarding, lost time and turnover. A poorly chosen staff augmentation model can produce low-quality leads that waste the closing team's time and distort pipeline metrics.
Neither mistake is cheap. That's why the decision deserves rigorous analysis, not a gut feeling.
In B2B sales, time is a critical factor. Every month without a robust pipeline is a month of revenue that can't be recovered. The difference between having an operational SDR in 2 weeks versus 3 months can represent tens or hundreds of thousands of dollars in lost opportunities.
SDR salaries vary significantly by market, experience and sector. In Latin America, a junior SDR can earn between $800 and $1,500 per month, while a senior SDR with experience in complex B2B sales can reach between $2,000 and $3,500 plus commissions.
In the United States, the ranges are significantly higher: between $45,000 and $65,000 annually for a junior SDR and between $65,000 and $90,000 for a senior SDR, plus commissions and benefits.
But the salary is just the tip of the iceberg.
Most companies underestimate the real cost of a direct hire because they only calculate the salary. The total cost includes:
Recruiting and selection: posting the position on job boards, HR team time or the cost of a recruiting agency, interviews and evaluations. In total, between $1,500 and $4,000 depending on the market and recruiting method.
Benefits and payroll taxes: depending on the country, mandatory benefits and payroll taxes can represent between 20% and 40% of the additional gross salary. In many Latin American countries, this includes social security, year-end bonuses, paid vacation, health insurance and other mandatory benefits. In the United States, benefits packages typically add 25% to 35% on top of base salary.
Equipment and licenses: laptop, phone, CRM licenses, prospecting tools like Apollo or LinkedIn Sales Navigator, email sequencer. Together, between $300 and $800 in additional monthly costs depending on the tech stack.
Management and supervision: the time a Sales Manager or Commercial Director dedicates to supervising, training and providing feedback to the SDR has a real cost even if it doesn't appear on any spreadsheet line. A junior SDR can require between 5 and 10 hours of weekly supervision during the first months.
Turnover: the SDR turnover rate is one of the highest in B2B sales, with averages of between 12 and 18 months of tenure. Every time an SDR leaves, the complete cycle of recruiting, selection and onboarding starts again.
The direct SDR hiring process follows a path that few companies can significantly accelerate:
Defining the profile and opening the position: 1 to 2 weeks. Posting and attracting candidates: 2 to 4 weeks. Interview and evaluation process: 2 to 3 weeks. Offer, acceptance and candidate notice period: 2 to 4 weeks. Initial onboarding: 2 to 4 weeks. Ramp to full productivity: 2 to 4 months.
In total, from the hiring decision to having an SDR generating qualified leads consistently, the process can take between 4 and 7 months. In many cases longer.
Hiring directly means assuming risks that many companies don't explicitly calculate: the risk that the candidate doesn't fit with the team culture, that they don't have the prospecting skills they demonstrated in interviews, that they leave within the first 6 months or that the market changes and the position no longer makes sense in that format.
The cost of an SDR via staff augmentation is a monthly fee that covers the professional's salary, benefits and payroll taxes, tools and tech stack, SDR management and supervision, the selection and onboarding process and replacement at no additional cost if the profile doesn't work out.
In Latin America, the monthly cost of an SDR via staff augmentation with a provider like Siete is typically between $2,500 and $5,000 per month depending on the profile, dedication and target market.
When you compare the real cost of staff augmentation with the total cost of direct hiring, the difference is significantly smaller than it appears at first glance.
A directly hired SDR in Latin America with a salary of $2,000 per month has a real total cost of between $3,200 and $4,500 per month when you include payroll taxes, benefits, tools, management and amortization of the recruiting cost. That's without counting turnover cost.
An SDR via staff augmentation at $3,500 per month includes all of that and also eliminates turnover risk, reduces ramp time and requires no upfront investment in recruiting.
The real cost difference between the two models is much smaller than the monthly fee number suggests at first glance.
This is where staff augmentation generates its greatest competitive advantage. The typical process is:
Profile definition and briefing: 2 to 3 days. SDR selection by the provider: 5 to 7 days. Client onboarding: 1 to 2 weeks. First active prospecting campaigns: week 2 or 3. First qualified leads: week 3 to 6.
In total, from the decision to the first results, the process can take between 3 and 6 weeks. Compared to the 4 to 7 months of direct hiring, the speed advantage is enormous.
With staff augmentation you can scale the team up or down based on results and business needs. If in one quarter you need three SDRs to cover an expansion campaign and in the next you only need one, you can make that adjustment without the costs and complexities of a team restructuring.
With direct hiring, that flexibility is practically nonexistent.
Direct hiring: 4 to 7 months to full productivity. Staff augmentation: 3 to 6 weeks to first results. Advantage: staff augmentation, by a wide margin.
Direct hiring: between $1,500 and $4,000 in recruiting alone, plus internal team time. Staff augmentation: generally no setup cost or a minimal onboarding cost. Advantage: staff augmentation.
Direct hiring: salary plus payroll taxes plus tools plus management. Staff augmentation: all-inclusive monthly fee. Advantage: similar or slightly favorable to staff augmentation when all real costs of direct hiring are calculated.
Direct hiring: very low. Scaling up requires new hiring processes. Scaling down involves layoffs with legal and severance costs. Staff augmentation: high. The team can be adjusted within weeks based on business needs. Advantage: staff augmentation, by a wide margin.
Direct hiring: high. If the SDR doesn't work out, replacing them costs the same time and money as the original hire. Staff augmentation: low. A serious provider includes replacement at no additional cost if the profile doesn't meet expectations. Advantage: staff augmentation.
Direct hiring: total. The SDR is part of the team, operates under your direction and culture. Staff augmentation: high when the provider operates in an integrated way with your team, as Siete does. Advantage: tie or slightly favorable to direct hiring in cases where provider integration is limited.
Direct hiring: depends entirely on the candidate you find in the market. Staff augmentation: the provider selects SDRs with specific experience in your industry or type of sale. Advantage: staff augmentation when the provider has the right talent pool.
Direct hiring makes sense when the company has time to wait for results, when the prospecting volume justifies an internal team of at least 3 to 5 SDRs, when the internal culture and processes are mature enough to onboard and develop junior sales talent and when the company is in a stability phase where flexibility isn't a priority.
Staff augmentation is the right decision when the company needs fast results, when the budget doesn't justify the fixed costs of a direct hire, when you want to validate a prospecting process before committing to an internal team, when entering a new market or segment and when flexibility to scale the team up or down is important.
For most growing B2B companies in Latin America, staff augmentation is the model that generates the best balance between speed, cost, risk and flexibility.
At Siete (Sie7e) we're a specialized agency in B2B lead generation and commercial staff augmentation for companies across Latin America and the United States.
