What to document before changing marketing agencies

If you are changing marketing agencies, the most expensive mistake is usually not the handoff fee. It is the quiet missing piece: one login nobody can find, one ad account tied to an old email, one tracking tag nobody documented, or one design file stored in a folder no one remembers. The work can look “moved over” while the business is still exposed to avoidable delays.

The fix is simple in theory and tedious in practice: document what you own, who can access it, what is being measured, and what rights you have to the creative and data. Do that before the relationship ends, not after.

Start with an ownership inventory

Make a plain list of every marketing asset tied to your business. The goal is not perfection; it is to answer, “What exists, where is it, and who controls it?”

Include things like:

• Website domain and hosting
• Business email accounts used for marketing
• Analytics and ad accounts
• Call tracking numbers
• Social media pages and business profiles
• Review platforms and directory listings
• Email marketing software
• CRM and lead intake forms
• Photo, video, and design files
• Landing pages and lead magnets

For each item, document the account name, the primary owner, the admin users, and where the recovery email or phone number goes. If an asset is registered to an agency employee’s personal email, flag it immediately.

A useful rule: if your business would struggle without it for a week, it belongs on the list.

Record access without sharing passwords badly

A clean handoff does not require emailing passwords around. In fact, it should not. Use a password manager or a secure access-sharing process so the business retains control and access can be revoked when needed.

Document:

• Which accounts use shared logins
• Which accounts should be converted to business-owned logins
• Which two-factor authentication method is enabled
• Who has backup codes
• Whether the agency is an admin, editor, or only a viewer

If you can, move toward role-based access instead of shared credentials. That way, the old agency can be removed cleanly without changing the business owner’s login details.

A hypothetical example: a neighborhood HVAC company might discover that its website, Google Business Profile, and paid search account are all connected to the agency’s staff email. Before switching, the owner should create business-controlled admin access, save recovery details, and then remove the agency only after the new team has confirmed everything works.

Capture tracking before it gets overwritten

Tracking is often the first thing that breaks during a transition because nobody thinks to document the “invisible plumbing.”

Before the switch, save screenshots or exports of:

• Website analytics settings
• Conversion goals and events
• Call tracking numbers and forwarding rules
• Form destinations and autoresponders
• UTM naming conventions
• Tag manager containers and notes about what each tag does
• Offline conversion imports, if any

Write down what counts as a lead for your business. A form fill? A phone call over a certain duration? A booked appointment? If the old agency used custom reporting, capture the logic behind it.

Be careful here: not every metric should be treated as a business outcome. If a report mixes impressions, clicks, calls, and qualified leads, note which numbers are useful for operations and which are just directional. That keeps the next agency from rebuilding the wrong dashboard.

Secure creative rights and source files

Many businesses have marketing assets they can see but cannot fully use. A logo may be in a PDF. An ad graphic may live only in an agency account. A video may be posted publicly, but the editable source file is nowhere to be found.

Document which files you own outright and which were licensed. Ask for:

• Editable design files
• Final exported versions
• Photo and video source files
• Copy documents for ads, emails, and landing pages
• Brand guides and style notes
• Any third-party licenses attached to the work

If there are stock images, fonts, or templates involved, note whether the license transfers or whether you need a new one. Also record any restrictions on reuse. That matters if you want to repurpose old campaigns under a new agency.

Tradeoff: collecting all source assets takes time, and some agencies may not have organized archives. Still, the extra effort is worth it because rebuilding from screenshots later is slower and more expensive.

Keep a short transition sheet for the new team

Once the inventory is done, turn it into a simple transition sheet. This should be readable in one sitting, not a sprawling folder nobody opens.

Include:

• List of accounts and owners
• Admin access steps
• Tracking summary
• Creative file locations
• Current campaigns and active budgets
• What should stay live during the handoff
• Deadlines or business events to avoid disrupting

If you are working with a new partner such as a fractional marketing lead, ask them to review the sheet before any changes are made. If you need help organizing a handoff, you can start a conversation through /contact.

What to avoid during the switch

Three common mistakes cause most handoff headaches:

1. Changing too much at once. If you redesign the website, rewrite ads, and switch analytics in the same week, it becomes hard to tell what broke.
2. Assuming access means ownership. Being able to log in is not the same as controlling the account.
3. Deleting old systems too early. Keep the old setup available long enough to confirm the new one is stable.

A slower, documented transition is usually better than a fast one that creates guesswork.

Action checklist

• List every marketing asset and who controls it
• Move important logins to business-owned accounts
• Save admin roles, recovery details, and backup codes securely
• Export tracking settings, reports, and conversion definitions
• Collect source files and confirm creative rights
• Write a one-page transition sheet for the new agency
• Remove old access only after the new setup is working

A good agency change is not just a transfer of tasks. It is a transfer of control, history, and responsibility. The more clearly you document those pieces now, the less you will have to reconstruct later.
