Should You Sign a 3, 6, or 12-Month Lead Gen Contract?
When each window makes sense, and the trade-offs between flexibility and pricing.
By the Launch Leads team · 5 min read · Updated April 2026
Pick the right lead gen contract length by starting with a 90-day pilot regardless of what the agency proposes. After the pilot, 6 months is the default for most engagements, 3 months is pilot-friendly for new relationships, and 12 months is only correct if you’ve already done a successful 6-month engagement with the agency, you have a defined large-volume need, or the discount is 15%+ paired with a 30-day notice window for early exit.
The agency proposed 12 months and you’re trying to figure out what’s standard.
Standard, in lead gen, is whatever benefits the agency. The 12-month default exists because it’s the agency’s preferred length — predictable revenue, slow exits, time to recover from weak early performance. Three months is the buyer’s preferred length — fast exit, low commitment, structural pressure on the agency to perform.
The right answer is somewhere in between, and depends on what you’re optimizing for.
The thesis: start with a 90-day pilot regardless of what the agency proposes. After the pilot, the right contract length is 6 months for most engagements, 3 months if the agency has a track record of fast ramp, 12 months only if you’re getting meaningful pricing concessions for the lock-in.

1. What each window actually buys you
3 months. The fastest path to “we know whether this works.” Pairs naturally with a pilot structure (see How to structure a pilot before committing). Best for new relationships, untested ICP segments, or category exploration. Trade-off: you’ll feel friction at month 4 if you want to continue — renegotiation work just as the engagement is hitting stride.
6 months. The sweet spot for most ongoing engagements. Long enough that the agency invests in iteration; short enough that you don’t have to live with a bad fit for a year. Best for established categories, defined ICP, and agencies you’ve worked with at least once before. Trade-off: 6-month commitments are typically priced 5–10% above 12-month equivalents.
12 months. Best for clients with predictable, high-volume needs and an agency they’ve already tested for 6 months and want to scale with. Worst for new relationships — locks you in before you have signal. Trade-off: lowest pricing, slowest exit, biggest risk if the relationship goes wrong.
2. The pricing trade-offs by length
Most agencies offer this rough discount ladder:
- 3-month: list price.
- 6-month: 5–8% discount on monthly fee, paid monthly.
- 12-month: 12–18% discount on monthly fee, often with a quarterly or upfront payment requirement.
The 12-month discount looks compelling. It’s also where the agency’s lock-in math lives. The discount is real; the value of the discount depends entirely on whether you’d have wanted to continue at month 7 anyway.
The way to think about it: a 15% discount on a 12-month contract you exit at month 9 is functionally a 0% discount, because you paid 3 extra months you didn’t want. A 15% discount on a 12-month contract you’d have continued at month 13 is a real 15%.
You don’t know which one you have when you sign. That’s why the 90-day pilot matters — it converts the unknown into a known before you commit to the longer term.
“They get up and running fast, the people they have are talented, they’re experienced. They’re people who understand how to sell to the types of customers that we deal with.”
— Eric Flynn, CEO, Treehouse Interactive
3. When to take the longer term anyway
Three situations where 12 months is the right call:
- You’ve already done a 6-month engagement with the agency and want to scale. The unknown is converted; the discount is real.
- You have a defined, large-volume need and the operational costs of switching agencies are higher than the lock-in risk. Common in enterprise inside-sales motions.
- You’re getting a meaningful pricing concession — 15%+ discount, paired with a 30-day notice window after month 6 for early exit. The concession compensates for the risk.
Outside these three, the 6-month contract is almost always the better trade. Lower lock-in risk, easier renegotiation, less leverage to the agency in the relationship dynamic.
4. The notice and renewal terms that matter more than length
Contract length is one variable. Notice window and renewal terms matter more.
A 12-month contract with a 30-day notice window after month 6 and no auto-renewal is functionally a 6-month contract with optional extension. A 6-month contract with 90-day notice and 12-month auto-renewal is functionally an 18-month commitment.
What to negotiate, in priority order:
- No auto-renewal — explicit re-signature required, not silence.
- 30-day notice window after the initial term, not 60 or 90.
- Early-termination right at month 3 if defined criteria aren’t met.
- Pro-rated refund for any unmet portion of qualified-meeting targets.
- Data and IP delivery in CSV within 14 days of termination.
Get all five and the contract length matters less. Miss any of them and the contract length is the agency’s leverage, not yours.

Frequently asked questions
What’s standard in lead gen contracts — 6 or 12 months?
12 months is what most agencies propose first. 6 months is what most engagements should actually be. “Standard” is the agency’s negotiation anchor; you’re not obligated to accept it.
What if the agency only offers 12-month contracts?
That’s a negotiation position, not a fact. Push for a 6-month structure. If the agency truly only does 12-month, run a 90-day pilot first as a separate engagement, then evaluate the 12-month. Don’t sign 12 months on month 1.
Should I sign a longer contract for a discount?
Only if (a) you’ve validated the agency through a 6-month engagement first, or (b) the discount is 15%+ and paired with a 30-day notice window for early exit. Otherwise the discount math doesn’t work.
Can I negotiate length down without losing the discount?
Often yes. Ask for the 6-month price at the 12-month rate in exchange for a renewal commitment if metrics hit. Many agencies will agree.
What’s the worst contract structure I should refuse?
12 months, 90-day notice, auto-renewal for another 12. That combination is the agency’s strongest lock-in and the buyer’s worst exit position.
