Unit Economics of a White-Label Shortener

This business has unusually clean economics: one flat cost, revenue that stacks client by client, and no percentage skimmed off the top. This lesson does the arithmetic properly — costs, break-even, per-client margin, lifetime value — with real platform numbers. The standing caveat from the track introduction applies to every table here: these are worked illustrations of mechanics. Your revenue depends on your prices, niche and effort, and nothing on this page is a promise of income.

Your cost side: flat, known, bounded

The platform subscription is sized by client capacity, not by your revenue — the full grid is on the pricing page:

| Plan | Monthly | Billed yearly (−20%) | Client workspaces | | --- | --- | --- | --- | | Starter | $49 | ≈ $39/mo | 25 | | Growth | $149 | ≈ $119/mo | 80 | | Scale | $399 | ≈ $319/mo | 250 |

Commission on your client revenue: 0%, structurally — the platform is never in your money path. Your other recurring costs are small and knowable: domain renewals (a few dollars a month), card processing inside your own Stripe or PayPal (roughly 2.9% + $0.30 per charge, by your provider's schedule), and whatever you spend on marketing. That last one is the only genuinely variable line, and the paid-channels lesson is about keeping it deliberate.

Notice what this cost shape means before any revenue arrives: your maximum monthly downside is the subscription plus loose change. This business fails cheap — which is exactly why the correct move is to launch fast and test demand with real prospects rather than protect yourself with months of planning.

Break-even: the first number to know by heart

Break-even is subscription ÷ average revenue per client. On Starter at $49, with processing fees rounded in:

| Your average price | Clients to break even | | --- | --- | | $9/month | 6 | | $19/month | 3 | | $29/month | 2 |

Six clients at the bottom of the market band. That is the honest entry bar of this business — not zero, but low enough that one good first-client week repeated a handful of times clears it. Write your own version of this number down; it turns the abstract question "will this work?" into the concrete question "can I find six restaurants?"

Per-client margin: why growth is quiet but relentless

Because the platform cost is flat, every client after break-even contributes their full price minus processing pennies. A $19 client costs you roughly $0.85 in Stripe fees and $0 in platform commission: ~$18 of monthly margin. Your own time is the real marginal cost — support, onboarding — and it is front-loaded: a client needs attention in week one and very little after (the retention lesson explains why that early attention is an investment, not overhead).

Assemble the pieces on Starter at an illustrative $19 average:

| Paying clients | Revenue | Platform | Processing (approx.) | Margin | | --- | --- | --- | --- | --- | | 3 | $57 | −$49 | −$3 | ≈ $5 | | 10 | $190 | −$49 | −$9 | ≈ $132 | | 25 (Starter full) | $475 | −$49 | −$21 | ≈ $405 |

The lesson of the table is its shape: the platform line never grows, so margin widens with every retained client. At 25 clients you have hit Starter's capacity — the upgrade decision that follows is the next lesson, and the table there shows it is a good problem.

Lifetime value: where pricing and retention multiply

Monthly margin understates what a client is worth, because clients stay for many months. Lifetime value in its simplest useful form:

LTV = monthly margin per client × average months retained.

A $19 client who stays 4 months is worth ~$72 to you; the same client retained 18 months is worth ~$326. Same price, same acquisition effort — four and a half times the value, all of it decided by retention. This single multiplication is why the Money track ends with a whole lesson on renewals, and why "cheap" acquisition that attracts short-lived clients is expensive in disguise.

LTV also disciplines your marketing spend: paying $40 to acquire a $72-LTV client is marginal; paying $40 for a $326-LTV client is excellent. You cannot judge any paid channel without an LTV estimate, even a rough one.

Reading your own numbers without self-deception

Three habits make these formulas useful rather than decorative:

1. Use real averages, not list prices. Your average revenue per client is actual MRR ÷ actual paying clients — discounts and old grandfathered prices included. The dashboard's billing view has both numbers; the weekly metrics lesson builds the ritual around them.
2. Estimate retention pessimistically until you have data. With under a year of history, assume single-digit average months. Upgrade the assumption when renewals, not optimism, justify it.
3. Count your hours honestly at the review, not per ticket. Time is a real cost, but metering every support minute poisons client relationships. Once a quarter, ask: does margin ÷ hours spent clear a rate you respect? If not, the fix is usually fewer, better clients at a higher average price — a pricing and niche decision, not a spreadsheet one.

Your assignment

Build your one-page model — twenty minutes, pen and paper is fine:

• [ ] Write your cost line: platform plan + domains + a realistic monthly marketing figure (zero is a valid start).
• [ ] Compute break-even at your prices from the pricing lesson. If it exceeds ~10 clients, your prices are likely too low for your plan tier — revisit before you market.
• [ ] Recreate the margin table for 5, 15 and 25 clients at your average price.
• [ ] Compute two LTVs: retention of 4 months and of 18. Sit with the gap for a minute.
• [ ] Mark your Starter capacity point (25 clients) and note the monthly revenue it implies — you will need that number in the next lesson.
