Definition

SQL

A Sales Qualified Lead (SQL) is a prospect that sales has evaluated through direct conversation and determined worthy of active pursuit—typically meaning they meet BANT criteria (budget, authority, need, timing) or equivalent qualification standards. SQLs represent the transition from marketing-nurtured leads to active sales opportunities in your pipeline. Whilst marketing qualified leads (MQLs) meet behavioural and demographic criteria suggesting interest and fit, SQLs require human verification through discovery calls where sales confirms genuine pain points, evaluates budget and timeline, and identifies decision-makers. Not all MQLs become SQLs—many turn out to be students researching, competitors gathering intelligence, or prospects lacking budget or authority. The SQL stage typically triggers CRM status changes, assignment to account executives for deal development, and formal pipeline forecasting. SQL criteria vary by organisation but generally include confirmed need for your solution category, identified pain or opportunity cost driving urgency, accessible decision-makers, realistic budget and timeline, and no obvious disqualifiers (wrong company size, location, or use case).

Importance

Why this matters

SQLs matter because they represent the filtered subset of leads actually worth intensive sales effort, preventing your team from wasting time on prospects unlikely to close. The distinction between MQL and SQL creates crucial accountability: marketing owns MQL-to-SQL conversion (lead quality), whilst sales owns SQL-to-opportunity and opportunity-to-close conversion. This clarity eliminates the blame-shifting common in revenue organisations where marketing claims sales doesn't follow up properly and sales claims marketing sends rubbish leads—now both claims are testable with clear metrics. For forecasting, SQLs provide much more accurate pipeline predictions than total lead counts because they've been vetted for genuine qualification. SQL volume and cost-per-SQL also guide marketing efficiency better than crude lead metrics: a campaign generating 1,000 leads but 10 SQLs is less valuable than one generating 100 leads but 30 SQLs, even though the first campaign wins on vanity metrics. The SQL stage also protects customer experience: prospects receive appropriately calibrated attention rather than aggressive sales outreach when they're merely researching or gentle nurture when they're actively comparing vendors. For scaling sales organisations, SQL definitions enable specialisation: SDRs (sales development reps) can focus on qualification conversations whilst account executives focus exclusively on qualified opportunities, dramatically improving productivity for both roles. The handoff also surfaces process gaps: if MQL-to-SQL conversion is extremely low, your MQL criteria need tightening; if SQL-to-opportunity conversion is low, your qualification questions need refinement. Organisations with tight MQL and SQL definitions consistently report 25-40% shorter sales cycles and 15-20% higher close rates because both marketing and sales focus on genuinely viable prospects rather than hopeful maybes.

Introduction

Introduction to

SQL

A Sales-Qualified Lead is a contact that both marketing and sales agree is now a real buying opportunity. The hand-off has already happened: a salesperson (SDR, AE, or partner) has spoken, chatted, or emailed with the prospect, confirmed key buying criteria, and decided to move the record into the sales pipeline as an Opportunity or Deal.

At minimum the rep validates four checkpoints—often called BANT:

  • Budget – Money (or realistic funding) exists for the solution.
  • Authority – The contact can sign or directly influences the signer.
  • Need – A clear, painful problem the solution can fix.
  • Timing – A concrete window to decide or implement.

If any checkpoint is weak, the lead is parked back in nurture or marked “disqualified.”

HubSpot uses Lifecycle stage = SQL and often auto-creates a Deal when a meeting is logged.

Pipedrive simply drags the card from Lead Inbox into the first stage of the chosen pipeline.

1.Establish shared criteria

Bring marketing, SDRs, AEs, and finance into one workshop. Choose the deal-winning traits—role, company size, industry, tech stack, pain, urgency. Document them on a single page titled SQL Definition v1.0 and store it in the playbook.

Sample SaaS criteria:

  • 50–500-employee B2B SaaS firm
  • VP Finance or C-suite sponsor
  • Sees benefit of automating revenue recognition in the next 90 days
  • Budget range £15 k–£50 k confirmed on call

2. Embed a qualification call script

Equip reps with a short, natural language checklist (not robotic interrogation). Example for an architecture firm using the BANT criteria :

Budget – “Have funds already been earmarked for design and planning?”

Authority – “Who else will review our proposal?”

Need – “What challenges prompted your search for a new architect?”

Timing – “When must planning permission be submitted?”

The rep fills four CRM fields—each “Yes”, “No”, or “Unknown.” Only when three or four show “Yes” does the lead advance to SQL.

3. Automate conversion and ownership

HubSpot workflow: when rep sets property BANT = Qualified → update Lifecycle stage to SQL, create Deal in Pipeline “New Business,” assign to AE, notify via Slack and email.

Pipedrive automation: dragging card into stage “Discovery” triggers task “Send recap and next-step email,” sets forecast amount, and reminds the rep in 48 hours if no activity.

4. Enforce a service-level agreement (SLA)

Inbound SLA – Marketing must ensure at least 70 % of SQLs arrive with Budget and Need confirmed.

Outbound SLA – SDRs contact every MQL within 24 hours and either convert to SQL or recycle within five working days.

Weekly dashboards expose SLA breaches so teams can course-correct quickly.

5. Close the feedback loop

Run a monthly MQL→SQL→Won review. If SQL→Won exceeds target but MQL→SQL lags, tighten marketing filters or improve SDR scripts. Continuous loops keep the funnel healthy.

Practical examples of SQL in B2B services

  • Creative agency – CMO of a 100-person fintech signs off budget for rebrand next quarter; timeline aligns with product launch.
  • IT managed service provider – Healthcare CIO needs 24/7 monitoring before ISO audit in 60 days; board approved £120 k budget.
  • Law firm – SaaS founder must update terms for EU expansion; legal spend earmarked; CEO is signer; deadline three months.
  • Bookkeeping firm – CFO of a £5 m ARR SaaS wants gap-free accrual accounting; demo completed; funds approved for Q1.

Each case shows budget, authority, need, timing—and therefore qualifies as SQL.

Conclusion

An SQL is where interest turns into opportunity. By defining clear shared criteria, embedding a friendly but firm BANT script, automating pipeline conversion, and enforcing SLAs, B2B teams keep the sales queue packed with winnable deals and the revenue forecast honest. Consistent SQL discipline unites marketing and sales, protects rep time, and signals to delivery and finance exactly how fast the business will grow.

Why most B2B marketers don't get the results they want

Most B2B marketers are either Random Ricks (trying everything) or Specialist Steves (obsessed with one channel). Generalists run tactics without strategy. Specialists hit channel ceilings. But there's a better way.

See entire course
Random Rick
Always-busy marketer

Tries everything at once. Posts on LinkedIn, runs ads, tweaks the website, chases referrals. Nothing compounds because nothing's consistent. Growth feels chaotic.

Specialist Steve
Single channel specialist

Obsessed with one tactic. 'We just need better ads' or 'SEO will fix everything.' Ignores the rest of the system. One strong engine can't carry a broken machine.

Solid Sarah
Full-funnel marketer

Finds the bottleneck. Fixes that first. Then moves to the next weakest link. Builds a system that's predictable, measurable and doesn't need 80-hour weeks.
