# CAC payback in 30 days and the 30-day cash collected rule

## TL;DR
- **Target payback ≤30 days.** A credit card gives about 30 days of interest-free money, so a 30-day payback lets a bootstrapped business fund unlimited growth without investors.
- **30-day cash rule:** gross profit collected from a customer in the first 30 days should be greater than **COGS + CAC** for that customer.
- If payback is 90 days, restructure the offer rather than accept it. Add setup fees, a paid onboarding, a front-end programme, a physical product bundled up front, prepaid durations, buy-one-get-two deals, or last month paid up front.
- Hormozi says every one of his businesses that got really big recovered CAC within the first 30 days.

## Details
**Why 30 days.** Alex Hormozi chooses 30 days for a practical reason. Almost any owner in the developed world can get a credit card. You spend $100 of card money to buy a customer, earn the $100 back before the statement is due, owe nothing, and still have the customer. Then you repeat that indefinitely.[^1][^2] Longer paybacks aren't wrong, but they cap growth at your cash reserves. Funded companies and giants (he cites Apple) can afford them. The ~24 of 25 people in his room who were bootstrapped can't.[^3] For founders who do raise money, a 30-day payback is what makes investors keen, and it also means you don't actually need them, which gives you leverage in the negotiation.[^3]

**Pulling cash forward.** Ask whether some configuration of your existing pricing and products would collect more cash up front without adding much operational drag. That question is what his *$100M Money Models* book is about. Tactics he lists:[^4]
- initiation or setup fees
- a defined front-end programme or onboarding sold up front, with continuity afterwards
- a physical product bundled with the service
- an extended period sold as a bundle and paid on day one
- buy one, get two
- last month paid up front

**The 30-day cash collected rule.** This goes one step beyond payback. Gross profit on cash collected in the first 30 days should exceed what it cost to **acquire and deliver** to that customer (CAC + COGS, where "goods" can be a service). Then each customer funds the next one.[^5][^6]

## Disagreements / caveats
- This is a bootstrapper's rule. Subscription apps with trials, or brands whose LTV builds from repeat orders, often can't reach 30 days without changing the model. The tripwire and upsell mechanics in web2app funnels are one way to get there ([[web2app-tripwire-pricing]], [[web2app-upsells-and-downsells]]).
- "Fund it on a credit card" only works if the payback is reliable. Volatile CAC can turn it into debt.
- **Subscription and rebill businesses deliberately run negative.** Stefan Georgi's peptide funnel lost ~$20 per new customer on day zero but netted positive daily cash from rebills. He'd accept a $300–500 CPA once rebill cash is flowing.[^7] CTC's Taylor Holiday says high-LTV brands like IM8 (~$308 CAC) win Meta's auction by financing longer paybacks.[^8] See [[paying-above-first-order-cac]].
