Your clients' stores are breaking. You're the last to know.

The agency monitoring problem

A typical ecommerce agency managing 20 Shopify clients faces a practical impossibility: you can't manually check 20 stores every day for new errors, performance regressions, or broken checkout flows. The first you hear about most bugs is when a client emails you, frustrated, asking why their conversion rate dropped. By that point, the damage has been done — and the client relationship has taken a hit.

The alternative is proactive monitoring: tools that watch your clients' stores continuously and alert you the moment something breaks. This changes the agency relationship fundamentally. Instead of reacting to client complaints, you're telling clients about problems before they notice. That's a retainer you can justify. That's a value proposition that clients understand.

What agencies need from error monitoring

Multi-store visibility

Agency monitoring needs a view across all stores, not just individual store dashboards. You need to see, at a glance, which clients have active critical issues, which stores have open error regressions, and which have Core Web Vitals scores that are trending into “poor” territory. Bloodhound's Enterprise plan includes a multi-store dashboard for exactly this.

Proactive alerting

Alerts should fire to a channel your team monitors — Slack, Microsoft Teams, or a custom webhook into your project management system. New errors, regressions, and performance threshold breaches all need to trigger notifications. The agency team shouldn't have to check dashboards; the dashboards should come to the team.

Client-facing reporting

Demonstrating value to clients requires reporting. Monthly or weekly summaries of issues caught, resolved, and their estimated revenue impact give clients a tangible view of what monitoring is doing for them. Bloodhound's weekly email reports (Business plan and above) give clients automatic visibility without requiring agency involvement in report generation.

API access for integration

Agencies with their own internal tooling — dashboards, project management integrations, Jira automations — need API access to pull Bloodhound data programmatically. The Enterprise plan provides per-store API tokens with access to issues, CWV data, script metrics, and security findings.

The monitoring retainer model

Proactive monitoring gives agencies a legitimate basis for a recurring retainer. The conversation changes from “we'll fix things when they break” to “we watch your store continuously and catch problems before they cost you money.”

The math works for clients. A store doing £300,000/year in revenue at a 3% conversion rate loses approximately £1,500 for every 0.1% of conversion rate drop. A single JS error caught and fixed in a day versus left for a month is the difference between £50 in lost revenue and £1,500. A monitoring retainer at £500/month is justified by preventing two such incidents per month.

The math works for agencies. Monitoring tooling at $49/month per store, sold as part of a £500/month retainer, represents a healthy margin on top of the time spent responding to alerts and fixing issues.

What to include in a monitoring service offering

A comprehensive ecommerce monitoring service offering from an agency should cover:

• Error monitoring: continuous capture and alerting on JS errors, with triage and response SLA
• Performance monitoring: weekly Core Web Vitals review, with quarterly performance audits
• Third-party script auditing: regular review of which scripts are loading and their performance impact
• Checkout monitoring: funnel analysis and error detection in the checkout flow
• Security auditing: monthly security header scan, secret leakage check, and supply-chain review
• Monthly reporting: executive summary of issues, actions taken, and estimated revenue impact

Common objections and answers

“My clients manage their own stores”

Even clients who manage day-to-day operations themselves benefit from having an expert in their corner who's watching for technical issues. The monitoring layer is separate from content management and marketing — it's infrastructure, not operational work.

“My clients already have Shopify's built-in analytics”

Shopify Analytics shows revenue, orders, and traffic. It doesn't show JavaScript errors. It doesn't show which third-party scripts are breaking the store. It doesn't show why conversion rate drops. There's no overlap.

“We only get called when something is obviously broken”

This is precisely the problem. The most expensive bugs are the ones that are subtly broken — affecting some users, on some devices, in some scenarios — and never obvious enough to trigger a support call. Error monitoring finds these. The reactive model misses them entirely.

Getting started as an agency

The practical approach for agencies:

• Install Bloodhound on one client store first — a client you have a good relationship with
• Let it run for two weeks and review the issues it surfaces
• Present the findings to the client: here are the errors that were running on your store, here's the estimated revenue impact, here's what we fixed
• Use that as a case study to roll out to other clients

In almost every case, the first store will surface at least one error that's had measurable revenue impact. That story sells the service.
