Most early-stage businesses are simultaneously over-tracking and under-tracking — drowning in dashboards that show traffic, follower counts, and CTRs, but unable to answer "did we make money this week?" without a 20-minute spreadsheet exercise. The fix isn't more metrics. It's the right five.
The five numbers that actually matter
- Monthly revenue. Not "annual run rate," not "pipeline" — money in this calendar month.
- Gross margin. Revenue minus the variable cost of delivering the product/service. A revenue line that grows but loses money per unit is a worse problem than no growth.
- Active customers. Whatever "active" means in your business — paid users this month, retainer clients on the books, units shipped. The denominator that matters more than total signups.
- Customer acquisition cost (CAC). Total marketing + sales spend divided by new customers acquired. Without this, you can't tell whether ad spend is working.
- Cash on hand. Bank balance minus committed-but-unspent obligations. The number that determines how many months you can survive at current burn.
Five numbers. One spreadsheet. Updated weekly. That's a complete metrics system for ~95% of small businesses, and it beats whatever expensive dashboard tool you'd otherwise be tempted to set up before having data worth dashboarding.
The metrics that look important but aren't
- Total followers / subscribers — vanity unless you can show a conversion path. 10k followers who don't buy is worse than 100 customers.
- Website traffic — useful as a leading indicator if you also know conversion rate. Useless on its own.
- Email open rates — Apple Mail privacy + bots have made this nearly meaningless since 2022. Click rates and replies still matter.
- Net Promoter Score — overrated for businesses under $1M revenue. Better signals: are people referring you? Do people renew?
- Time on page, bounce rate — analytics theater. Real signal is: did the page produce a desired action?
Where to pull each number from
- Revenue + active customers: Stripe directly. The Stripe dashboard is enough; export CSV monthly.
- Gross margin: Wave, QuickBooks, or a manual cost model in your spreadsheet.
- CAC: Spend (ads, tools, sales time) ÷ new customers. Spreadsheet column.
- Cash: Your bank account. Updated manually weekly.
None of this needs a paid dashboard tool. If you're spending more than 30 minutes per week on metrics, the system is over-engineered.
The weekly cadence that works
Monday morning, 30 minutes:
- Open the metrics spreadsheet.
- Update the five numbers from their sources.
- Look at last 4 weeks of trend.
- Write one sentence: "Last week was up/down/flat because ___."
- Decide one action for this week based on what you saw.
That's the whole ritual. Done weekly for a year, you'll know your business at a depth that no dashboard tool would have given you.
When you outgrow the spreadsheet
Three signals: (1) you have a team that needs to see the same numbers, (2) data updating manually is taking 2+ hours a week, (3) you need real-time vs weekly. At that point, a tool like Geckoboard, Databox, or self-hosted Metabase pays back. Until then, the spreadsheet is the right tool — fast, flexible, and visible to the only person whose decisions it informs (you).
The one number to overweight
Pick one of the five as your "headline metric" — the number that, if it moves, everything else follows. For most early-stage businesses, this is monthly revenue. For some, it's active customers (because the revenue model isn't proven yet). For pre-revenue, it's a leading indicator like qualified conversations. Track all five. Optimize for the one. Avoid the trap of optimizing for whichever metric is currently up.
