Essential Metrics & Valuation Tips for SEIS and EIS B2B SaaS Investments

Why SEIS and EIS Matter for B2B SaaS Investments
SEIS and EIS schemes exist to fuel the UK startup scene. They reward angels and retail investors with hefty tax breaks. For a B2B SaaS investment, here’s why they matter:
-
Up to 50% Income Tax Relief
SEIS offers 50% relief on investments up to £100k. EIS gives 30% relief on up to £1 million. -
CGT Exemption
Profits on shares held for three years are free from Capital Gains Tax. -
Loss Relief
If the startup bombs, you can offset losses against your income tax. -
Portfolio Diversification
Tax reliefs make it easier to back multiple SaaS bets.
That cushion changes your risk–reward calculus. But don’t let it lull you into sloppy diligence. You still need to pick winners.
Eligibility and Requirements
Before you click “invest,” check:
- The company is UK-registered and qualifies as a trading entity.
- At least 70% of activities are commercial (no property flipping!).
- Share issues must be new shares, held for at least three years.
- No more than £150k raised under SEIS previously (or £5m under EIS).
Meet those, and you’ve earned your seat at the table.
Key Metrics to Bookmark in B2B SaaS Investments
Venture capitalists live and die by metrics. SEIS/EIS investors should too. Here’s the shortlist:
Monthly & Annual Recurring Revenue (MRR / ARR)
- Why it matters: Predictability. You can forecast next quarter.
- Target: Fast-growing deals often show >10% monthly MRR growth. ARR multiples inform valuations.
Churn Rate
- Why it matters: Retention = long-term value.
- Target: <1% monthly churn (or <5% annual). Higher churn sends warning bells.
Customer Acquisition Cost (CAC) & Payback
- Why it matters: Efficiency. How fast does the startup recoup marketing and sales spend?
- Target: CAC payback in under 12 months. Faster is better.
Lifetime Value (LTV) to CAC Ratio
- Why it matters: Profitable growth.
- Target: LTV:CAC ≥ 3x. Below 2x? You’re burning cash.
Average Revenue Per User (ARPU)
- Why it matters: Monetisation health.
- Target: Steady ARPU growth signals cross-sell and up-sell success.
Burn Rate and Runway
- Why it matters: Survival. How long until they need cash again?
- Target: Minimum 12 months runway. Ideally 18–24 months after your cheque clears.
These metrics guide your term-sheet conversations. They also factor into your valuations and exit planning.
Valuation Approaches for SEIS/EIS Rounds
Valuing a young B2B SaaS can feel like guesswork. Blend these methods for a more balanced view:
1. Market-Based Multiples
Use ARR multiples from comparable SaaS deals. Public SaaS firms might trade at 8–12x ARR, while seed rounds often land at 4–8x. Adjust for:
- Growth rate
- Gross margins
- Capital efficiency
2. Discounted Cash Flow (DCF)
Project cash flows three to five years out. Then discount by a high rate (25–40%) for risk. Best for later SEIS/EIS rounds where forecasts aren’t total fantasy.
3. Venture Capital Method
Work backwards from your target exit value. Decide on a 10x or 15x return. Estimate the company’s exit valuation. Solve for today’s price per share.
Adjusting for Tax Relief
Remember: SEIS/EIS relief lowers your effective cost basis. Factor that in:
- Shrink your valuation hunch by the relief percentage.
- Consider the tax refund timing—income tax relief comes after your tax return.

Structuring Your SEIS/EIS Deals
Your term sheet must protect you. Common instruments:
-
Convertible Notes & SAFEs
Quick. Fewer negotiations. But watch for cap tables. -
Equity Financing
Straight shares. Often paired with board seats or observer rights. -
Preferred Shares
Liquidation preferences. Anti-dilution clauses. They tilt the table in your favour. -
Milestone Tranches
Release funds when the startup hits MRR targets or hires key execs.
Aligning your interests with founders is crucial. Milestones and liquidation preferences ensure both sides stay hungry.
Exit Strategies & Risk Management
An exit plan is a risk-control tool. Here’s where SEIS/EIS investors shine:
Strategic Acquisitions
A larger tech player buys the SaaS for its IP or customer base. These exits can fetch 5–12x ARR.
IPOs
Public markets reward scale and profitability. But only a handful of EIS-backed firms make it there.
Secondary Sales
Late-stage rounds or secondary transfers let early investors cash out partially before a big exit.
Risk Controls
- Monitor Burn & Runway monthly.
- Revisit CAC & LTV every quarter.
- Scenario-Plan for downturns or rapid expansion.
- Stay Engaged: join board meetings or investor calls.
SEIS/EIS investing isn’t “set and forget.” It’s active oversight with tax breaks as a bonus.
