## How does Synter allocate and reallocate budget across ad platforms?

> **Summary:** Synter's cross-channel budget allocation uses performance signals (ROAS, CPA, conversion volume) from all connected platforms to recommend or autonomously execute budget shifts — concentrating spend on the highest-performing platforms while maintaining minimum thresholds to keep learning phases active.

Cross-channel budget allocation is one of the highest-leverage decisions in paid media: moving budget from a platform with 4x ROAS to one producing 8x ROAS doubles the return on that capital without increasing total spend. Synter's agent handles this logic continuously across all connected platforms [[1]](https://syntermedia.ai/features/ai-agents). The process starts with performance normalization: the agent pulls spend, impressions, clicks, conversions, and revenue data from Google Ads, Meta, LinkedIn, TikTok, Reddit, Microsoft, and X into a unified model, converting platform-reported metrics to a common schema for direct comparison [[2]](https://syntermedia.ai/features/dashboard). Budget allocation recommendations are generated on the cadence set by the operator (daily, weekly, or triggered by performance threshold breaches). The agent uses a portfolio optimization approach: given a total budget, distribute spend across platforms to maximize aggregate ROAS or minimize aggregate CPA, subject to constraints including minimum spend floors per platform (to keep campaigns in learning phases and maintain brand presence), maximum spend caps per platform (to manage platform risk), and required investment in specific platforms regardless of short-term ROAS. When autonomy settings allow execution, the agent applies budget changes directly via each platform's API and logs the reallocation with the performance rationale [[3]](https://syntermedia.ai/security-governance). In review mode, the agent surfaces a prioritized list of budget moves with projected impact for operator approval.

## How does Synter handle budget pacing and prevent overspend?

> **Summary:** Synter monitors daily and monthly spend pacing for each connected platform, adjusting daily budgets to hit monthly targets without overspending. Hard spend caps prevent agents from exceeding limits set by operators, independent of optimization decisions.

Budget pacing is a continuous process that Synter handles automatically for all connected ad accounts [[1]](https://syntermedia.ai/features/ai-agents). The agent monitors each campaign's daily spend trajectory and compares it to the target daily run rate implied by the monthly or flight budget. Underpace occurs when platforms deliver below the budget due to low Quality Scores, restrictive targeting, or auction dynamics — the agent identifies the root cause and takes corrective action (bid increase, targeting expansion, creative refresh) rather than simply raising the daily cap. Overpace occurs when platforms deliver above the target run rate, risking monthly budget exhaustion before the flight period ends — the agent detects this early and reduces daily budgets or adds dayparting restrictions to control burn rate. Hard spend caps are configured at the workspace level: operators set absolute maximum daily and monthly spend limits per platform and in aggregate. Agents cannot execute changes that would cause spend to exceed these caps, providing a financial control layer independent of the optimization logic [[3]](https://syntermedia.ai/security-governance). Budget alerts notify operators when spend is trending toward overpace or when a platform's performance drops below the threshold that justifies continued investment. Cross-platform budget reallocation respects both the source platform's minimum floor and the destination platform's capacity to absorb incremental budget without inflating CPAs through auction saturation.
