40% SDR Attrition: Sales Outsourcing Models and Costs for B2B Teams

Sales outsourcing means paying an outside firm, contractors or an AI-run service to do some or all of your selling: prospecting, appointment setting, follow-up or closing. Judge it against the in-house seat it replaces. The Bridge Group’s 2025 survey of 351 B2B companies puts median SDR pay at US$80K on-target, with a 3.0-month ramp and 40% annual attrition.

Sales outsourcing at a glance

• Five seats you can hand over: prospecting, first response and setting, follow-up and reactivation, closing, and account growth. Most firms outsource one or two, not all five.
• Five models: staff augmentation, managed SDR or setting agency, commission-only closers, full-cycle outsourced team, and AI-first pay-per-result.
• The in-house yardstick (Bridge Group, 2025): $80K median SDR on-target earnings, 10 held meetings a month median quota, 60% of reps at quota, 40% median annual attrition.
• The break-even: on our labelled assumptions, an in-house SDR seat costs about $1,528–$1,698 per held meeting at 80% attainment. That is the number an outside offer has to beat.
• The legal point: outsourcing the calls does not outsource the liability. Under the US Telemarketing Sales Rule the seller stays responsible for its do-not-call list.

What sales outsourcing is (and the five seats you can hand over)

Sales outsourcing is any arrangement where people who are not your employees perform part of your sales process under your brand, paid by fee, by result or both. It is a decision made seat by seat, not all at once.

Sales outsourcing covers five distinct seats; three of them produce an output you can count and pay on, which is why those three are the ones most often outsourced.

Seat	What it does	Output you can count	Our deeper guide
1. Prospecting	Builds lists and makes the first outbound touch	Conversations started	Outsourced SDR
2. First response and setting	Answers inbound leads and books meetings	Meetings booked and held	Appointment setting outsourcing
3. Follow-up and reactivation	Works leads that went quiet and old databases	Meetings booked from aged leads	—
4. Closing	Runs the sales call and asks for the order	Deals closed, revenue	Commission-only closers
5. Account growth	Renewals, upsell, expansion	Revenue retained and expanded	—

This page covers the whole function. Where a single seat already has its own guide, it is linked above rather than repeated here.

How it works

How to outsource sales one seat at a time

01

Map the five seats

List prospecting, setting, follow-up, closing and account growth. Note who does each today.

02

Run the Seat Test

Ask Count, Coverage and Judgement of each seat. Outsource seats that pass Count and Coverage and fail Judgement.

03

Set the break-even

Work out your in-house cost per held meeting, including ramp, turnover and management. That is the price to beat.

04

Pilot, then decide

Run a fixed pilot with written meeting definitions and a review date. Decide on held meetings and close rate, not activity.

Why companies outsource sales in 2026

Companies outsource sales because an in-house sales seat is slow to fill, slow to ramp and quick to empty. The Bridge Group’s 2025 report on sales development, based on 351 B2B companies (78% North America-based, 83% B2B SaaS), gives the numbers:

• Ramp: 3.0 months on average before an SDR is productive.
• Attrition: 40% median annual attrition, with a 25th–75th percentile range of 21%–57%.
• Tenure: 1.9 years on average.
• Attainment: 60% of reps at quota, the lowest in the study’s history.

Time is the other pressure. In Salesforce’s survey of 7,775 sales professionals (August–September 2022), reps said they spend just 28% of their week actually selling. Outsourcing a seat is often a way to give the remaining in-house sellers more of that week back.

The quotable line: sales outsourcing is less about cheaper labour than about not carrying the empty months of a seat that turns over 40% a year.

Five sales outsourcing models, compared

There are five common sales outsourcing models, and the real difference between them is who carries the risk when the work produces nothing.

Five sales outsourcing models compared on what you pay for and who carries the risk; only commission-only and pay-per-result models move most of the no-result risk to the provider.

Model	Seats usually covered	How it is usually priced	Who carries the risk of no results	Wrong for
Staff augmentation (dedicated contract or offshore reps)	Prospecting, setting	Hourly or monthly per rep	You	Teams without a sales manager to run the reps day to day
Managed SDR or appointment-setting agency	Prospecting, setting, follow-up	Monthly retainer, often plus a per-meeting fee	Mostly you	Offers with a very small, already-known buyer list
Commission-only closers	Closing	Percentage of closed revenue	Mostly the closer	Offers without a steady supply of booked, qualified calls
Full-cycle outsourced sales team	Prospecting through closing	Retainer plus commission	Shared	Products where the buyer expects to meet the founder or engineers
AI-first, pay-per-result service	First response, setting, follow-up, reactivation	Per appointment, revenue share, or a mix	Mostly the provider	Businesses that want to build and own a setter team

Pricing for each model varies by provider; read each provider’s own pricing page rather than relying on a summary. For the difference between paying on output and paying for effort, see our guide to pay-for-performance marketing.

Which sales seats to outsource: the Seat Test

The Seat Test is a three-question rule for deciding, seat by seat, what to outsource and what to keep. Ask each question of each of the five seats:

1. Count: can the seat’s output be counted and agreed by both sides (a held meeting, a closed deal)? If not, you cannot contract for it cleanly.
2. Coverage: does the work need more hours than one person’s shift (evenings, weekends, several time zones) or arrive in uneven bursts? If so, a provider can spread it across people or systems.
3. Judgement: does doing it well depend on knowledge you cannot write down in a few pages (pricing exceptions, technical scoping, relationship history)? If so, keep it.

Outsource a seat when it passes Count and Coverage and fails Judgement. Keep it when it passes Judgement, whatever the other two say.

The Seat Test applied to all five sales seats: setting and follow-up usually pass Count and Coverage and fail Judgement, so they are the default first seats to outsource.

Seat	Count	Coverage need	Judgement need	Usual verdict
Prospecting	Yes (meetings held)	Medium	Medium (messaging, targeting)	Outsource if you can write the ideal-customer definition in a page
First response and setting	Yes	High (leads arrive any hour)	Low	Outsource first
Follow-up and reactivation	Yes	High (long, patient cadences)	Low	Outsource first
Closing	Yes (revenue)	Low to medium	High for complex or custom offers	Keep in-house unless the offer is standard and repeatable
Account growth	Partly	Low	High (relationship history)	Keep in-house

If you are weighing the closer seat specifically, our guide on whether commission-only closers are worth it goes deeper.

Sales outsourcing benchmarks: the in-house numbers to compare against

The fairest benchmark for any sales outsourcing offer is the in-house seat it replaces. These are the median figures from The Bridge Group’s 2025 SDR report, which you can use until you have your own:

The Bridge Group’s 2025 medians for an in-house SDR seat: $80K on-target earnings for a quota of 10 held meetings a month, with 60% of reps reaching it.

Metric	2025 figure	Note
Median SDR on-target earnings	$80K	$55K base / $25K variable; unchanged since 2022
Monthly quota, held meetings (Stage 0)	10	Global median, down 40% since 2018
Share of SDRs at quota	60%	Lowest in study history
Average ramp time	3.0 months	Lowest since 2010
Median annual attrition	40%	25th–75th percentile 21%–57%
SDRs per first-line leader	6.4	Down from 8 in 2021–2023
SDR manager on-target earnings	$146K	Up from $127K in 2018

Sample caveat: the respondents are mostly North American B2B SaaS companies with a $50K median average selling price, so the dollar figures are US-market and the meeting quota reflects SaaS sales cycles. A consumer or local-services business should replace them with its own numbers. For a US cost breakdown of the SDR seat alone, see how much an SDR costs in the USA.

Worked example: the vacancy-adjusted break-even for sales outsourcing

The vacancy-adjusted break-even is the cost per held meeting of an in-house seat once ramp, turnover and management are included. Any outsourced offer priced per held meeting below it costs less on paper. The worked example uses the Bridge Group medians above plus labelled assumptions.

Inputs from the report: $55K base, $25K variable at quota, quota of 10 held meetings a month, 3.0-month ramp, 40% attrition, 6.4 SDRs per manager, $146K manager on-target earnings.

Assumptions (ours, illustrative, replace with yours): on-costs (payroll taxes, benefits, equipment, software) add 25%; variable pay scales with attainment; no meetings during ramp; a departing rep leaves a 2-month vacancy before the replacement starts ramping; recruiting costs roughly offset the salary saved while the seat is empty.

1. Rep cost at 80% attainment: ($55,000 + $20,000) × 1.25 = $93,750.
2. Manager share: $146,000 ÷ 6.4 × 1.25 = about $28,516.
3. Seat cost: $93,750 + $28,516 = about $122,266 a year.
4. Year one (new hire): 12 months minus 3 ramp = 9 productive months × 8 meetings = 72 held meetings. $122,266 ÷ 72 = about $1,698 per held meeting.
5. Steady state: 40% attrition × (2 vacancy + 3 ramp months) = 2 months lost a year, so 10 productive months × 8 = 80 meetings. $122,266 ÷ 80 = about $1,528 per held meeting.

On these assumptions an in-house SDR seat costs about $1,528 to $1,698 per held meeting at 80% attainment, and about $1,934 to $2,148 if attainment is 60%.

Attainment (assumption band)	Held meetings a month	Seat cost a year	Cost per held meeting, year one (9 months)	Cost per held meeting, steady state (10 months)
60%	6	$116,016	$2,148	$1,934
80%	8	$122,266	$1,698	$1,528
100%	10	$128,516	$1,428	$1,285

What the break-even leaves out, honestly: the in-house rep builds product knowledge and relationships you keep; the outsourced meeting may be of different quality; and a provider that charges per booked rather than per held meeting needs your show rate applied before you compare. Adjust for those before deciding.

The quotable line: compare an outsourced meeting with the cost of a held meeting from a seat that is sometimes empty, not with a salary divided by twelve.

How to outsource sales in seven steps

A sales outsourcing project succeeds or fails in the set-up weeks, before any provider makes a call. The sequence that works:

1. Run the Seat Test and pick one seat to start. Setting or follow-up is usually the safest first seat.
2. Write the qualified-meeting definition in a page: who counts, which questions must be answered, what disqualifies. Our lead qualification framework is a starting template.
3. Measure your baseline for at least a month: leads, contact rate, meetings booked, meetings held, deals closed.
4. Shortlist providers by model, not by brand, using the five-model table. Ask each for reporting samples and a reference in a similar offer.
5. Agree the scripts and the handoff: how a booked meeting arrives in your calendar and CRM, with notes.
6. Run a fixed pilot with a review date and the metrics agreed in advance.
7. Decide on the numbers at the review: held meetings, cost per held meeting against your break-even, and close rate on outsourced meetings versus your own.

What to put in a sales outsourcing contract

A sales outsourcing contract should define the output, protect your data and keep compliance responsibility visible, because outsourcing the work does not outsource the liability.

• Definitions: what a qualified meeting, a held meeting and a no-show are, in writing.
• Data ownership: every lead, recording and note belongs to you and is returned on exit, in a stated format.
• Reporting: weekly, at lead level, not just totals.
• Brand and scripts: what the provider may say about your offer, price and guarantees.
• Exit: notice period and what happens to meetings already booked.
• Compliance: who maintains do-not-call lists, consent records and calling-hour rules. In the US, the FTC’s guidance on the Telemarketing Sales Rule states that a seller is ultimately responsible for keeping a current entity-specific do-not-call list, whether through a telemarketing service it hires or its own efforts. In Australia, ACMA manages the Do Not Call Register; check the rules in each market you call. Our do-not-call compliance guide covers the US detail. This is general information, not legal advice.

Where sales outsourcing goes wrong

Sales outsourcing usually goes wrong for reasons that were visible before the contract was signed. The common ones:

1. No agreed definition of a qualified meeting, so both sides report success and the closers disagree.
2. No baseline, so nobody can tell whether the provider moved anything.
3. Outsourcing the judgement seat first. Handing complex closing to strangers before handing over setting reverses the Seat Test.
4. Paying for activity, not output, then arguing about dial counts.
5. Thin handoff, so meetings arrive without notes and the closer starts from zero.
6. Data left on the provider’s systems, so leaving means losing the pipeline history.
7. Judging too early or too late: a review date set before the pilot starts avoids both.

The quotable line: a sales outsourcing failure is usually a definition failure that shows up three months later as a results failure.

What I’d fix first before outsourcing sales

If a business asked me to outsource its sales next month, I would do these things first, in this order:

1. Measure what happens to leads you already have. Response time and follow-up depth on existing leads are often the cheapest fix available.
2. Run the break-even table with your own numbers. If your in-house cost per held meeting is already low, outsourcing a seat should be about coverage, not cost.
3. Outsource one countable seat, usually setting or follow-up, and keep closing in-house until the meetings prove themselves.
4. Pay on output where you can, with the definitions written down.

In our own client work we typically see a business still running 2020-style sales operations rather than 2026 AI-driven ones convert roughly 300% better once the gaps are closed; speed to lead alone is often around 3x, doubling contact rate around 2x, and doubling set rate around 2x. That is an operator observation, not a study, and the levers do not multiply: 3x × 2x × 2x is not 12x, because they overlap.

How LeadsNow applies sales outsourcing

LeadsNow takes the countable seats in the Seat Test: first response and setting, follow-up and reactivation of older leads. We book calls using AI calling, SMS and DM follow-up, into your calendar; your team keeps the offer, the price and the close.

• Volume: 50,769+ AI-booked sales appointments since 2017 and 1M+ leads generated.
• Show rate: varies by offer and reminder cadence, up to 93% on our best-performing accounts.
• Sales lift: a 7x average sales lift, as defined on our methodology page, which also discloses that the median is closer to 4x.
• Track record: 24 filmed client case studies and a 4.7 rating from 60 Google and Facebook reviews.

The service itself is described on our AI appointment setting page.

LeadsNow: a pay-per-result way to put this into practice

LeadsNow is priced on results: 5–25% of the revenue we generate for you (revenue share), or an equivalent pay-per-appointment fee, and the two can be combined as a revenue share, a fee per appointment, or a mix of both. Where you land depends on lead volume, what is being sold and its price, the type of product and business, and which part (or all) of the sales funnel we run. Details are on our pricing page.

• No-shows aren’t charged.
• Bad-fit dials and the cost of contacting the many people who never book are our cost, not yours.
• No retainer; cancel any time with 14 days notice.
• We are the wrong fit if you want to outsource complex closing or account management, or to build and own an in-house setter team.

FAQ

What is sales outsourcing?

Sales outsourcing is paying an outside firm, contractors or an AI-run service to perform part or all of your sales process under your brand, such as prospecting, appointment setting, follow-up or closing, paid by fee, by result or a combination.

Is it cheaper to outsource sales than to hire?

It can be, but compare like with like. Using The Bridge Group’s 2025 medians and our labelled assumptions, an in-house SDR seat costs about $1,528 to $1,698 per held meeting at 80% attainment once ramp, turnover and management are counted.

Which part of my sales process should I outsource first?

Start with a seat whose output can be counted and that needs more hours than one shift, usually first response and appointment setting, or follow-up on older leads. Keep closing and account management in-house until the outsourced meetings prove themselves.

How do outsourced sales companies charge?

The common structures are hourly or monthly per rep, a monthly retainer often with a per-meeting fee, a percentage of closed revenue for closers, retainer plus commission for full-cycle teams, and per-appointment or revenue-share pricing for pay-per-result services.

Am I still responsible for compliance if I outsource sales calls?

Generally yes. In the US, the FTC’s Telemarketing Sales Rule guidance says a seller is ultimately responsible for keeping a current entity-specific do-not-call list, whether through a telemarketing service it hires or its own efforts. Check the rules in every market you call.

Does sales outsourcing work for small businesses?

It works when there is enough countable work to hand over: a steady flow of leads or a defined list of reachable buyers. With only a handful of leads a month, the owner answering them quickly usually beats any provider.
