A thinking tool
Sales, cost and stock
are one machine.
Most shop owners are handed five separate pieces of advice. They are not five things — they are one equation with a factory bolted to the end of it. Move the sliders and watch profit, cash and reorder timing move together.
What the factory hands you
Set to 0 if you make it yourself and never wait on a factory
Including box, label and inbound freight
What you charge
This is what decides how fast one production run clears
Finding new customers
Ads, paid reviews, content — every baht spent to get discovered
Keeping the ones you have
How long one unit lasts is your repurchase cycle
Where the order is placed
No marketplace cut, and you keep the customer contact
Three panels, starting from the constraint you do not get to choose. Change anything — every chart below re-reads.
Month 12 — once the machine is up to speed
Numbers settle after a year of building a repeat base · Type a target and the model works backwards to the driver
Where one order's money goes
The factory clock — lot after lot, seamlessly
The funnel at month 12
Where you lose the most people
12 months of revenue, split by who paid
View as a table
Cash in hand over 12 months
You pay for the first lot before you sell anything, then earn it back
If you could move only one lever
Extra profit per month, measured from your current numbers
The five things this makes visible
A deliberately simple model, built to show direction and priority rather than to forecast sales. The customer base is a cohort: each cycle a share returns at the repeat rate and the rest is treated as churned. All figures are in Thai baht.
This is the first hour of a project.
We build the systems that make these numbers real — POS, stock, storefront, the reporting that tells you which lever actually moved. Scoped honestly, operated for years.
