A founder I know hit 4.5 months of runway last year. She didn't panic. She ran through a version of this playbook and bought herself 11 months. No new funding. No layoffs. Just nine moves executed in the right order over six weeks.
Here's the thing about runway extension: most of the advice out there is either obvious (“spend less”) or requires outside capital (“raise a bridge round”). This playbook is for when you need to extend runway with the resources you already have, starting this week.
I'm going to use a baseline of a company burning $120K/month with $540K in the bank. That's 4.5 months of runway. The goal: get to 10+ months.
Move 1: Kill Zombie Subscriptions ($2K–$8K/month)
Every company has them. SaaS tools that someone signed up for, used for a project, and forgot about. The average SMB has 4–7 subscriptions that nobody has logged into in 90+ days.
Run a usage audit. Check the last login date for every tool you're paying for. If nobody's used it in 60 days, cancel it. If someone complains, you can re-subscribe. They almost never complain.
Typical savings: $3K–$5K/month for a 30-person company. One founder found $4,200/month in dead subscriptions, including a $900/month analytics tool that the marketing team had replaced six months earlier.
Move 2: Renegotiate Your Top 5 Vendors ($3K–$10K/month)
Sort vendors by annual spend. Take the top five. Call each one and say: “We're reviewing all our vendor relationships to reduce costs. We want to stay with you, but we need a better rate. What can you do?”
Most vendors would rather give you 15–20% off than lose you entirely. SaaS companies have 70–80% gross margins. They have room to negotiate.
Typical savings: 10–20% off your top 5 vendors. If those five total $30K/month, that's $3K–$6K/month.
Move 3: Switch to Annual Billing Where It Saves Money ($1K–$3K/month)
This one's counterintuitive when you're trying to preserve cash. But many SaaS vendors give 15–20% discounts for annual vs. monthly billing. If you have the cash and the tool is one you'll definitely use for 12+ months, the upfront payment reduces your effective monthly burn rate.
Be selective. Only do this with tools you're certain about. The worst thing is paying annual upfront and canceling at month four.
Move 4: Accelerate Collections ($5K–$20K one-time, then ongoing)
Check your accounts receivable aging report. How much is sitting in 30+, 60+, 90+ day buckets? For most SMBs, 15–25% of outstanding AR is past 30 days.
Three things to do immediately:
- Send a personal email (not an automated one) to every customer with a balance over 45 days. “Hey, just checking in — noticed this invoice is outstanding. Any issues?”
- Offer a 2% discount for payment within 10 days on new invoices. You lose 2% on the invoice but gain 20–50 days of cash.
- Shorten your default payment terms. If you're at Net 45, go to Net 30. If you're at Net 30, go to Net 15.
Typical impact: Pulling in $20K–$50K of outstanding AR in the first two weeks, plus ongoing improvement in cash conversion cycle.
Move 5: Delay Non-Critical Hires (Variable, Often $8K–$15K/month per role)
This isn't “don't hire.” It's “delay the hires that won't generate revenue in the next 90 days.” That ops coordinator you were going to bring on? Push it 90 days. The second designer? Table it until runway is above 8 months.
Every role you delay saves $8K–$15K/month in fully loaded cost (salary + benefits + equipment + overhead). Two delayed hires can add 1–2 months of runway by themselves.
Move 6: Move to Contractors for Variable Work ($3K–$7K/month)
Some roles don't need to be full-time. If you have a full-time employee doing work that fluctuates — design, content, QA — switching to a contractor for that function can cut costs 30–50% while maintaining output for the hours you actually need.
The trade-off is real: contractors are less embedded in your culture, slower to ramp, and less available. But when you're extending runway, the math matters more than the ideal org chart.
Move 7: Renegotiate Payment Terms with Your Own Vendors ($2K–$5K/month effective)
If you're paying vendors on Net 15 or Net 30, ask to move to Net 45 or Net 60. Most vendors will agree, especially for established relationships. This doesn't reduce your costs, but it shifts when cash leaves your account, which directly impacts runway calculations.
For a company paying $80K/month to vendors, moving from Net 30 to Net 60 effectively adds one month's worth of vendor payments ($80K) to your available cash. That alone could be an extra month of runway.
Move 8: Audit Your Infrastructure Costs ($1K–$4K/month)
Cloud costs are notorious for growing unchecked. Unused instances, oversized databases, dev environments running 24/7, that staging server from the feature branch you abandoned in October.
Run a right-sizing exercise on your AWS/GCP/Azure account. Look for instances running at under 20% CPU utilization. Check for unattached storage volumes. Review your reserved instance coverage.
Typical savings: 20–35% of cloud spend. For a company spending $8K/month on infrastructure, that's $1,600–$2,800/month.
Move 9: Revenue Acceleration (Variable, but Often the Highest Impact)
This one isn't about cutting costs. It's about pulling revenue forward.
- Offer annual prepay discounts. Give customers 10–15% off for paying annually upfront. You give up some margin but you get 12 months of cash immediately.
- Launch a limited-time offer. Create urgency for prospects who are evaluating. “Lock in 2025 pricing before March 31” works better than you'd think.
- Upsell existing customers. Your best source of new revenue is your current customer base. What can you offer them that they'd pay more for?
Putting It Together
Back to our example company: $120K/month burn, $540K cash, 4.5 months runway.
If they execute moves 1–8 aggressively:
- Zombie subscriptions: –$4K/month
- Vendor renegotiation: –$5K/month
- Annual billing savings: –$2K/month
- Delayed hires (2 roles): –$20K/month
- Contractor conversion: –$4K/month
- Infrastructure audit: –$2K/month
New burn rate: $83K/month. Plus they pulled in $35K in outstanding AR and gained an extra $80K from extended vendor payment terms.
New runway: ($540K + $35K + $80K) / $83K = 7.9 months. Add revenue acceleration and they're above 10. That's the difference between survival and scramble.
The key is speed. Don't spend three weeks analyzing. Start with the easiest wins and work through the list in order. Most of these can be initiated in a single week.
