FAQ

Why does one won project absorb so much of an ID firm's ad spend?

At RM80k–RM500k project values, a single won project generates the bulk of monthly revenue. If ad spend is RM8k and one project of RM100k is won that month, ad spend equals 8% of revenue on that single project. Miss a month and the same ad spend becomes 100% of revenue. Volatility is the real risk.

What does the minimum viable project value tell me?

It is the project value at which the month's ad spend, divided across the projects won that month, stays under a self-imposed threshold. Firms with lumpy months should stress-test at one won project rather than the average.

What inputs should I use?

Your real monthly ad spend across Meta, Google and other channels, your real projects-won-per-month count from your job board, and your real average project value. No industry defaults are assumed.

Quick answer

Ad spend as a share of revenue = monthly ad spend ÷ (projects won × average project value). A firm spending RM8,000 to win 1 project of RM100,000 is at 8%; miss the month and that same RM8,000 becomes 100%.

Under a 10% acquisition ceiling, minimum viable project value is RM80,000. Pair with the quote-to-close calculator. Property developers modelling launch-phase pacing (a different economics question with unit values in six and seven figures) should read the Malaysian property marketing agency hub for how the same input frame changes at property-vertical scale.
