ครีเอทีฟโฆษณา SaaS สไตล์มินิมอลพร้อมใบแจ้งหนี้

A minimalist static SaaS advertisement on a warm off-white background with elegant editorial typography. Top section: a large black serif headline in two lines reading: "[Your dev team shouldn’t be your analytics team.]" with "dev team" in italic serif and the remaining text in bold high-contrast serif with generous tracking. Center section: top-down view of a slightly tilted white paper invoice with soft drop shadow and a subtle vertical center fold crease. The invoice features black monospaced typewriter text reading: "INVOICE — DEV HOURS, OCTOBER" header, followed by five column-aligned line items: "A/B test setup on pricing page 8 hrs $1,200", "GTM tag install (3 events) 4 hrs $600", "Funnel tracking debug 6 hrs $900", "Meta pixel mapping 3 hrs $450", and "Attribution reporting build 12 hrs $1,800". Below the items is a dashed horizontal line, with bold monospaced "TOTAL" on the bottom-left and "$4,950" on the bottom-right. A bright yellow marker line strikes through "$4,950". Four doodle marker annotations frame the invoice: on the left, handwritten yellow text "every month??" with a yellow arrow pointing right toward the invoice; on the top right, a yellow starburst doodle; below the total, a green curved arrow curving up toward the crossed-out price; and on the lower right, a green hand-drawn circle containing the handwritten words "zero devs" attached to the green arrow. Bottom section: centered two-line black sans-serif body copy reading: "[Marketers ship tests and track revenue themselves. No tickets. No tag manager. One script.]". Clean, spacious layout blending startup graphic design with realistic tactile paper textures.
