Fig. TL-A, three instruments, each a link to its tool. AI cost check: The comb meter at the check’s opening example: 40 actions a month pour through the q/b mark into a US$20 seat with room for 48 lines, and fill 1.1 of 48 lines. Export invoice check: The export invoice check’s ruler: the specimen invoice’s ten lines, seven carried and three still loose, then its dates to scale, from the invoice to the day the money must be in India. Studio hours: The planner’s specimen week, Monday to Sunday: job hours hatched in ink, studio hours combed in blue, the weekly review one lemon hour on Sunday.

Open the AI cost check

The opening example as use grows: the cost a user a month at three tiers of one provider, against one seat price; the middle tier meets the seat at its break-even, dimensioned under the chart.

One rule each, drawn.

The same rules, dates and words as the kits, and the sources each one was checked against.
