How an Agency Migrated 15 Clients in 1 Week

A performance marketing agency managing 15 e-commerce and lead gen clients was drowning in manual sGTM configurations. GetCAPI Business gave them centralized control, saving 80% of their setup time and delivering better results for every client.

The Challenge

Manual sGTM management for 15 clients was unsustainable

1

Each client required a separate sGTM setup

Every new client onboarding required 2-3 days of developer time to set up server-side Google Tag Manager, configure tags for each ad platform, and test the entire flow. With 15 clients, this consumed most of the agency's technical resources.

2

No centralized visibility or management

Each client's sGTM container was an isolated silo. Checking match rates, debugging issues, or rolling out updates meant logging into each container individually. There was no way to see overall health at a glance.

3

Inconsistent results across clients

Different team members had set up different clients, leading to inconsistent configurations. Some clients had 85% match rates while others were stuck at 60%, with no clear reason why.

The Solution

GetCAPI Business with multi-container management and team collaboration

The agency migrated all 15 clients to GetCAPI Business over the course of one week. Using template configurations, the team created standardized setups for common client profiles (Shopify + Meta, WooCommerce + Google, etc.) and deployed them in minutes per client. The multi-container dashboard gave the entire team visibility into all accounts, while role-based access ensured junior team members could manage day-to-day operations without risk.

“Before GetCAPI, onboarding a new client's server-side tracking took 2-3 days of developer time. Now our account managers do it themselves in under an hour. We migrated all 15 clients in a single week, and every one of them saw better conversion data immediately. It's become our secret weapon in new business pitches.”
