Template Debt Ratio

Template Debt Ratio is the count of live render templates a client account depends on divided by the number of people who can safely edit them. A ratio above roughly 10:1 means every campaign change routes through one technical owner, and that owner becomes a single point of failure for delivery. Agencies win high-volume visual retainers by templating once and rendering many times, but the template library quietly accumulates variants: seasonal banners, regional copy swaps, per-platform crops. Bannerify's REST API and Figma-style editor make the first ten templates cheap and the two-hundredth expensive, because each one needs naming, versioning, and a fallback when a field breaks. AppScreenshots shows the healthier pattern, bundling 14-language translation into one asset definition rather than 14 separate files. Audit the ratio quarterly, retire templates nobody rendered in 90 days, and document the field schema before adding a new client to the pipeline.
