| Said | Means | Hard |
|---|---|---|
| our buyers | the 4,180 US property managers the customer sentence matches | Yes |
| the store | the platform with the largest share of those accounts and a store that lists integrations | Yes |
| 10 reviews | asked of design partners the week their result lands, after the listing is live | No |
| Way | Time to first customer | Cash per customer | At scale, customers a month | Your hours a week | Loaded CAC |
|---|---|---|---|---|---|
| Partnerships and marketplaces | 60 days (35 to 120) | $300 ($5 to $600) | 5 (1 to 20) | 5 (1 to 20) | $490 |
Days are to the first paying customer; cash leaves out your hours, and loaded CAC adds them at $100 an hour. Planning estimate unless a source is named: how each was set.
The decision
Pick the platform whose store already reaches the most of your buyers. Three tests decide it. A large share of your approved accounts run it. Its store shows demand for your job. The integration takes 40 to 80 of your hours. Find your first customers reads the share from your approved accounts.
Estimate the demand before you build. Read the store’s own search for your job with Keyword.search, and count the installs of the listings that rank: where a store hides installs, reviews × 20 to 50 is a fair estimate, so a rival with 40 reviews has about 800 to 2,000 installs. A category whose top three together show under 1,000 installs will not fill a funnel of 5 customers a month.
Build the smallest integration that delivers your core result inside the platform. List it with the job in the title and the result in the first screenshot; Make content drafts it. Ten reviews in the first 30 days set its rank, so line them up with Review requests before it goes live.
Partners shorten deals and keep integrated customers longer. Treat that as the reason to try, never as a forecast: your own store numbers replace every planning number here by week 12. Integration partners runs the partner side, and Weekly readout reads both.
The math
customers a month = listing views × view to install × install to active × active to paid
| Input | Value | Basis |
|---|---|---|
| Accounts that fit | 4,180 | Leaseline’s market count |
| Share that run the platform | 40% | The software read on your approved accounts |
| Category page views a month | 2,400 | The store’s listing analytics |
| View to install | 5%; measure your own | A listing whose first screenshot shows the result |
| Install to active | 30% | Set up on install, with no separate account |
| Active to paid | 15% | A trial that ends on a card |
| Installs per review | 20 to 50 | Stores that show both counts |
| The store’s share | 20% of revenue | The store’s published partner terms; 0% to 25% across stores |
| Listing fee | about $1,000 a year | A listing or security-review fee, where the store charges one |
| The build | 40 to 80 of your hours over 3 to 4 weeks | The smallest integration that delivers the core result |
Planning estimate unless a source is named: how each was set.
Reachable accounts = 4,180 × 40% = 1,672, read by Pick who to sell to from the software each account's site runs.
Customers = 2,400 × 5% = 120 installs; × 30% = 36 active; × 15% = 5 paying. That is about 5 customers a month at scale from one store category, at about $300 cash a customer.
Cash CAC counts what the store takes: its 20% of a $149 customer's first 12 months after churn is $149 × 20% × 9.19 = $274, and the listing fee over a year's 60 paying customers adds $17. With $5 of data that is about $300 cash a customer.
The build is priced too: 40 to 80 of your hours is $4,000 to $8,000 loaded, spread over the first 12 months of installs: $100 a customer at 60 hours, plus an hour a week of upkeep. That is 1.9 hours a customer and $490 loaded, paid back in 4.5 months at $149, inside the $795 the price can afford. Across the first quarter that averages about 5 hours a week of yours. Marketplace listings runs the listing, and Competitor gap shows who already ranks in the store.
Playbook
| Step | Move on when |
|---|---|
| 1. Read the software your approved accounts run, and rank platforms by share | Lead with a platform 30% or more of them run |
| 2. Read the store’s search for your job and the installs of who ranks, before you build | The top three show 1,000 installs or more together, counting reviews × 20 to 50 where installs are hidden |
| 3. Read the store’s share, fees, publishing rules and review time | Review under 4 weeks; cash CAC with the share under half of what your price can afford |
| 4. Build the smallest integration that delivers your core result | 40 to 80 of your hours, and set up on install with no separate account |
| 5. Write the listing: the job in the title, the result in the first screenshot, a 30-second video, the price in text | Listing submitted by week 4 |
| 6. Ask each design partner for a review the week their result lands | 10 reviews within 30 days of going live |
| 7. Pitch the partner’s team one co-marketing item after 5 shared customers | One joint guide, template or directory feature by week 12 |
| 8. Read installs, activation and partner revenue by listing every week | 3% or more of views install by week 12 |
Worked example
Leaseline integrates with a property-accounting platform that 38% of its approved accounts run, read by Pick who to sell to. The store’s search for rent tracking ranks three listings with 25, 40 and 60 reviews, about 2,500 to 6,250 installs between them, and the category page shows 2,400 views a month. The build takes the founder 60 hours over 3 weeks. With no store at 30% of its accounts, it would lead with Hands-on.
Launch kit writes the listing, and the founder submits it in the store’s own console. Listing check reads it daily until it is live.
At 5% view to install, the listing brings 120 installs a month, and Silence watch follows each one to activation. 36 activate and about 5 pay, at $149 a month. Review requests asks ten design partners in its first 30 days, and its rank rises with their reviews.
About 5 customers a month from one store category, $745 of new monthly revenue, at $300 cash and $490 loaded a customer once the store's share, the listing fee and 60 build hours are counted.
When it breaks
| Symptom | Cause | Fix | Fix with |
|---|---|---|---|
| Listing views that install (under 1%, a month after approval) | The first screenshot does not show the result. | Lead with the result screen and a 30-second video. | Content.update |
| Installs that activate (under 20%, at 50 installs) | Setup needs an account in your app first. | Create the account on install, signed in through the platform. | Customer.activate |
| Reviews on the listing (under 10 reviews, 60 days after going live) | No ask at the moment the result lands. | Ask each design partner the week their result lands. | Review.request |
| Partner replies (under 1 reply, after 5 asks) | No shared customer yet. | Ask again after 5 shared customers, and name them. | Message.schedule |
| Store review time (over 28 days, per submission) | The listing breaks a store rule. | Read the rules before building, and fix the rule the store cites. | Post.update |

Good looks like
| When | The number | Target | Below this, do |
|---|---|---|---|
| Week 1 | Share of your approved accounts that run the chosen platform | 30% | Under 30%: no store fits yet; lead with Hands-on. |
| Week 4 | Integration built and the listing submitted | 1 listing in review | Not submitted by week 6: cut the integration to its one core result. |
| Week 12 | Listing views that install, with 10 reviews or more | 3% | Under 3%: rewrite the first screenshot, then ask for more reviews. |
