How to Run Facebook Ads for Clients: Complete Agency Guide

Managing Facebook ads for clients is fundamentally different from managing your own campaigns. You need proper account structures, clear processes, professional reporting, and ironclad asset protection. Get it wrong, and you risk losing access, damaging client relationships, or exposing yourself to liability.

This guide covers everything you need to know to run Facebook ads for clients professionally—from account setup to ongoing management and reporting.

Account Access Options

The first decision when onboarding a new client: how will you access their ad account? There are three primary approaches, each with tradeoffs.

Option 1: Partner Access (Recommended)

Partner access through Meta Business Manager is the gold standard for agencies. The client grants your agency Business Manager access to their assets without transferring ownership.

How it works:

  1. Client has their own Business Manager with ad account and Pixel
  2. Client adds your agency's Business Manager as a partner
  3. Client assigns specific permissions (advertiser, analyst, admin)
  4. You manage ads through your own Business Manager interface

Advantages:

  • Client retains full asset ownership
  • Clean separation—if partnership ends, access is simply revoked
  • Professional, audit-friendly setup
  • No password sharing required

Disadvantages:

  • Requires client to have Business Manager setup (you may need to help)
  • Initial setup takes more time

According to Meta Business Manager best practices, "Business Manager solves this by centralizing assets and turning access into a permission model you can audit."

Option 2: Agency-Owned Ad Account

You create and own the ad account under your Business Manager, then run ads on the client's behalf.

When to use:

  • New businesses without existing Facebook presence
  • Clients who want fully managed, hands-off service
  • White-label arrangements

Advantages:

  • Full control over setup and structure
  • No dependency on client technical skills
  • Billing under your account

Disadvantages:

  • Client loses ownership if relationship ends
  • Potential conflicts over historical data access
  • More liability on your side

Option 3: Direct Ad Account Access

The client adds you directly to their personal ad account or gives you login credentials.

Why to avoid this:

  • Security risk (shared credentials)
  • No audit trail
  • Messy ownership and permissions
  • Unprofessional

Only consider this for very small clients or informal arrangements—and transition to proper Business Manager setup as soon as possible.

Permission Levels Explained

When setting up partner access, assign appropriate permission levels:

Permission Level What They Can Do
Admin Full control—add/remove people, change settings
Advertiser Create and manage ads, view performance
Analyst View reports only—no editing ability

Most agencies need Advertiser access on ad accounts and Analyst on Pixels. Only request Admin if you're managing the entire Business Manager.

Client Onboarding

A structured onboarding process sets expectations and prevents problems. According to industry research, "agencies that establish realistic KPIs during onboarding achieve 15-20 percentage point better retention."

Pre-Onboarding Checklist

Before launching any campaigns, collect:

Business Information:

  • Business name, website, industry
  • Products/services being advertised
  • Target geographic areas
  • Unique selling propositions

Account Access:

  • Business Manager ID
  • Facebook Page access
  • Instagram account (if applicable)
  • Pixel/Conversions API status

Campaign Requirements:

  • Budget (daily/monthly)
  • Objectives and KPIs
  • Timeline and launch dates

Technical Setup Checklist

Setting Expectations

During onboarding, clearly define:

  1. Communication cadence – Weekly updates? Monthly calls?
  2. Reporting schedule – When and what format
  3. Approval workflow – Who approves ads before launch?
  4. Response times – SLA for requests and changes
  5. Budget changes – How much notice needed for adjustments

Document everything in a kickoff document or onboarding agreement.

Reporting

Professional reporting separates agencies from freelancers. Clients pay for transparency and insights—not just ad management.

What to Include in Reports

Performance Metrics:

  • Spend vs. budget
  • Results (conversions, leads, purchases)
  • Cost per result (CPA, CPL, CPS)
  • Return on ad spend (ROAS)
  • Click-through rate (CTR)
  • Cost per click (CPC)

Trend Analysis:

  • Week-over-week or month-over-month changes
  • Performance by campaign/ad set
  • Top performing ads
  • Audience insights

Insights and Recommendations:

  • What's working and why
  • What needs optimization
  • Tests to run next period
  • Budget recommendations

Reporting Frequency

Client Type Recommended Frequency
High-spend clients (>$10k/month) Weekly reports, bi-weekly calls
Medium-spend ($2k-$10k/month) Bi-weekly reports, monthly calls
Low-spend (<$2k/month) Monthly reports and calls

Reporting Tools

Native Options:

  • Meta Ads Manager custom reports
  • Export to spreadsheet

Professional Tools:

  • Data Studio/Looker Studio – Free, customizable dashboards
  • Agency reporting platforms (Supermetrics, AgencyAnalytics, etc.)
  • Custom dashboards via APIs

Data-driven agencies "demonstrate ROI, optimize future campaigns, and strengthen client confidence" through measurement and transparent reporting.

Best Practices

After managing hundreds of client accounts, here are proven best practices.

Naming Conventions

Standardize naming across all client accounts:

[Client]_[Objective]_[Audience]_[Date]

Examples:
AcmeCo_Conversions_Retargeting_2601
AcmeCo_Traffic_ColdProspecting_2601
AcmeCo_Leads_Lookalike_2601

Consistent naming makes reporting easier and prevents confusion across multiple clients.

Campaign Structure

Use a clean, scalable structure:

  1. One campaign per objective – Don't mix conversion and awareness goals
  2. Logical ad set grouping – By audience, placement, or creative test
  3. 3-6 ads per ad set – Enough for testing, not so many it dilutes budget
  4. Clear creative labeling – Identify concept, format, and version

Budget Management

  • Never exceed approved budget without written client approval
  • Set campaign budget limits as a safety net
  • Document all budget changes with timestamps
  • Monitor daily during launches and high-spend periods

Creative Management

  • Get approval before launching new creative concepts
  • Keep a creative library organized by client
  • Track creative fatigue – refresh ads every 2-4 weeks
  • Document what works for each client

Communication

  • Proactive updates on significant changes (good or bad)
  • No surprises – inform clients before they check Ads Manager
  • Clear, jargon-free language in reports and calls
  • Document all decisions in writing

Protecting Client Assets

  • Use partner access, not personal credentials
  • Enable two-factor authentication on your Business Manager
  • Limit admin access to senior team members only
  • Regular access audits – remove departed employees immediately
  • Document asset ownership in contracts

Frequently Asked Questions

Should I use my ad account or the client's?

Use partner access to the client's ad account whenever possible. This protects both parties—the client retains ownership, and you're not liable for payment issues. Only create agency-owned accounts for new businesses or specific white-label arrangements where ownership is clearly documented.

How do I handle a client who wants login access?

Educate them on Meta's partner access system. Explain that sharing credentials violates Meta's terms of service and creates security risks. Set them up with their own Business Manager if needed, then have them add you as a partner. Most clients appreciate the professionalism once they understand the benefits.

What if a client doesn't pay?

This is why account ownership matters. If you're using partner access, continue managing ads while resolving the payment issue separately—you can pause campaigns if needed. If you own the account, you have more leverage but also more risk. Always have clear payment terms in your contract, and consider requiring payment in advance for new clients.

How many clients can one person manage?

It depends on account complexity and service level. General guidelines:

  • Full-service management: 5-10 clients per manager
  • Media buying only: 10-20 clients per buyer
  • Light management: 20-30 clients per person

Quality suffers beyond these ranges. Scale with proper systems and team expansion.
