The best-practice model for a hybrid in-house and external agency team is for the brand to own the shared workflow while each agency manages its own internal production process. A brand-owned marketing project management platform should hold the briefs, deadlines, deliverables, feedback, approvals and final assets. Agencies can use their own production tools, provided agreed milestones, versions and decisions are recorded in the brand's system.
This gives the brand visibility and control without requiring agencies to adopt every internal process.
Hybrid delivery is now common in larger marketing organisations. The internal team typically handles high-volume, fast-turnaround work — social, digital, adaptations, always-on content — while external agencies take the larger campaigns, specialist production and projects that benefit from outside thinking. In its 2023 research, the Association of National Advertisers reported that 82% of respondents had an in-house agency, and 92% of those organisations continued to work with external agencies as well.
What follows is how to run that arrangement so it does not generate a weekly reconciliation job for someone in marketing.
Hybrid teams get into trouble when responsibility is divided by organisation rather than by deliverable. Assign four roles to every project instead.
| Role | Typical owner | Responsible for |
|---|---|---|
| Business owner | Brand or marketing lead | The objective, the budget and the outcome |
| Project owner | In-house project or marketing manager | The brief, schedule, workflow and project record |
| Delivery owner | In-house team or agency | Producing the agreed deliverable |
| Approvers | Brand, legal, compliance, product | Reviewing and formally approving |
The brand should retain: the approved brief, project priorities, brand and compliance requirements, budget approvals, stakeholder decisions, final marketing approvals, and the approved assets and campaign record.
The agency should own: its production process, its internal resourcing, creative development, delivery against agreed scope and milestones, and flagging risks before they hit a deadline.
Getting this written down prevents the most common hybrid failure: the agency believes it is waiting on the brand, the brand believes work is progressing, and a week disappears.
Every project needs its own brief, and every brief should start the same way whether the work goes to your internal team or to an agency. Consistency matters more than the format — an agency receiving a different standard of brief to your studio will produce a different standard of work.
A complete creative brief covers:
Use a online form rather than a document, or better still use online briefing templates to ensure consistency and completeness . Marketing project management software such as Simple Admation can make the important fields compulsory, ask conditional questions, and route the request to the right place. Selecting "regulated product campaign", for example, can automatically request substantiation for claims and add legal and compliance to the reviewer list, while a standard social post follows a much shorter path.
A project should not begin simply because someone submitted a request. Insert a checkpoint:
This is one of the most effective controls in a hybrid setup. It stops incomplete requests becoming urgent projects, and it means an agency never starts work on a brief your own team has not signed off.
Brand consistency is where hybrid working creates the most risk, because you now have two or more groups producing work and only one of them sits inside your building.
Off-brand work becomes far more likely when external partners have no direct access to current brand assets and guidelines. They work from whatever they were last sent, whenever they were sent it — so an agency using a logo variant that was superseded two updates ago is behaving reasonably given the information it has. The failure is in the distribution method, not the partner.
What fixes it:
Simple Brand Manager is built for this, and there is more detail in keeping a brand consistent across teams and markets. In regulated industries, centralised brand asset management also supports marketing compliance, because it helps you confirm that published material used the same brand elements, claims and disclaimers that were approved.
External partners do not need to see every internal project. Use role-based permissions so each partner accesses only what their work requires.
Agency users typically need to: view the approved brief, see the schedule and their assigned deliverables, download approved brand assets, upload drafts and new versions, respond to feedback, update progress, record time or costs where required, and see decisions that affect their work.
They should not automatically access: other agencies' commercial information, confidential internal discussions, unrelated campaigns, unapproved strategic material, personal or sensitive information, or executive and compliance conversations that do not involve them.
Two requirements matter more than they first appear. Agencies working on the same brand should not see each other's work — they compete, they pitch against each other, and creative approaches and rates are commercially sensitive. And you need one view across all of them, or the only complete picture of the campaign lives in a spreadsheet maintained by one person.
Teams routinely confuse comments with sign-off. Someone writing "looks good" in a chat thread is not a formal approval, and treating it as one is how unapproved work reaches market.
Run two distinct stages.
Collaborative review — the internal team, the agency and any subject matter experts discuss the work and resolve creative questions.
Formal approval — named decision-makers approve or reject a specific version inside your marketing approval workflow, which records the comment, the version and the decision against the asset.
A sound marketing approval process gives you comments directly on the asset, one consolidated feedback record, version control, defined review stages, approval deadlines and reminders, per-reviewer status, the date, time and identity of every decision, a record of exactly which version was approved, and an exportable audit trail.
Complete your internal review before asking the agency to make changes. They should receive one consolidated and prioritised set of feedback, not conflicting comments from ten stakeholders they cannot rank.
A practical sequence:
Not every project needs every stage. The workflow should adjust to campaign type, cost, risk and channel. A low-risk organic social post might need one marketing approver. A national financial services campaign might need brand, product, legal and compliance. A rebrand might add procurement, executive and regional sign-off.
Approval templates let you define these once per work type rather than rebuilding the routing every campaign.
One point specific to working with agencies: bring legal and compliance in at the copy and claims stage, before layout. They are reviewing wording, and wording settles early. Waiting until final artwork means their changes ripple through every format the agency has already produced — and you pay for that rework.
A common hybrid setup looks like this:
Each tool works. The system does not, because no single place answers the questions that matter.
Test yours. From one platform, can you answer:
Chat and email are fine for discussion. Decisions need to land in the project record.
Most hybrid setups draw on four categories, and the first decision is which of them you actually need.
| Category | What it does | Best suited to |
|---|---|---|
| General project management | Tasks, schedules, assignments | Teams coordinating work, without formal creative review |
| Marketing project management | Briefs, creative projects, proofing, approvals, campaign records | Brands managing complex briefs and multiple partners |
| Online proofing | Mark-up, versions, review and sign-off | Teams with project management already, needing better creative review |
| Brand and digital asset management | Approved assets, permissions, version control, distribution | Giving internal teams and agencies controlled access to current assets |
A smaller team with straightforward work may be fine with general project management plus online proofing. Brands running several agencies, regulated marketing or multi-stage approvals generally need purpose-built marketing project management, because that is the category that keeps the brief, the project, the feedback, the approval history and the final asset connected to each other.
Worth being clear on one term, because it causes confusion. Agency management software usually means software an agency uses to run its own business — clients, time, billing, profitability. What a brand needs for a hybrid model is marketing project management software: the same creative workflow, but owned by the brand and extended to its partners.
Whichever category you land on, check a shortlist against what a hybrid team actually needs:
That last one is worth asking early. Where a platform charges per external reviewer, teams start rationing access: two logins for the agency instead of four, external legal left out because it is not worth another seat. The workflow you designed reverts to email, and the reason is commercial rather than practical.
For a comparison of specific platforms, see our guide to the best marketing project management software.
Agency relationships end, and when they do the approval history should not leave with them. If it lived in the agency's system it goes; if it lived in email it is technically retained and practically unusable. Either way an incoming agency starts from a verbal handover and your compliance team has a gap.
The brand should hold the master schedule, the approval record and the final asset library regardless of who produced the work.
Simple Admation is marketing project management and approval workflow software for brands managing work across internal teams, agencies and external stakeholders. It is built around this model, and the governing principle is that the brand sets the rules — the platform provides the controls, and how they are configured is your decision.
Where approvals cross into a genuinely separate organisation — an underwriter, a joint-venture partner, a client of yours — the same platform handles it through partner approvals, with each side running its own internal review privately. That is covered in cross-organisation marketing approvals.
It also works from the other direction. Where an agency holds the account and runs several clients through it, each client sees only their own projects and data, and agency staff see only the accounts they work on. Our agency use case covers that view.
You can see the model in practice in our a2 Milk Company case study, where internal teams across four markets and external digital agencies work in one approval process.
One brief per project. One shared project record. One controlled feedback process. One documented approval trail.
Your agency does not need to adopt your internal processes. It needs to work within your governance at the points that matter: briefing, milestones, asset submission, feedback, approval and final delivery. Get that right and moving work between internal and external teams becomes a decision rather than a disruption.
The internal team generally owns brand strategy, priorities, stakeholder management and final approval, while the agency provides specialist capability, additional capacity or outside perspective. In most brands the internal team handles high-volume fast-turnaround work such as social, digital and adaptations, while agencies take larger campaigns and specialist production. The arrangement works when the brand owns the workflow — briefs, deadlines, deliverables, feedback, approvals and final assets — while each agency keeps control of its own internal production process. Problems usually start when briefs change informally or feedback reaches the agency through several channels at once.
Through a staged workflow that sets out who reviews at each point and who has authority to approve. A typical sequence runs from internal creative review, to brand review, to legal or compliance review where required, to final approval by a named decision-maker. Two things make it work: separating collaborative discussion from formal sign-off, so a comment in a chat thread is never mistaken for approval; and consolidating internal feedback before it reaches the agency, so they receive one prioritised set of changes rather than conflicting comments from stakeholders they cannot rank.
Give scoped access configured per partner rather than either full access or file transfer. An agency producing work typically needs the approved brief, the schedule and its own deliverables, approved brand assets, the ability to upload versions and respond to feedback, and visibility of decisions affecting its work. It should not automatically access unrelated campaigns, other agencies' commercial information, confidential internal discussion or unapproved strategy. Access should be revoked centrally when the engagement ends, without relying on the agency to delete the copies it holds.
Give both groups the same live source of approved assets rather than sending files out. Off-brand work from external partners is almost always the result of working from whatever they were last sent, so the fix is access rather than distribution: current approved logos, colours, typography and imagery in one place, with usage rules attached at the point of download and superseded versions removed from circulation. Scope access per partner so an agency working on one market cannot reach another's material, and use locked templates for work produced outside the creative team.
Yes, provided the platform isolates partners rather than simply adding them as guests. This matters commercially rather than socially, since agencies compete for the same accounts and creative approaches and rates are sensitive. Each agency should see only its own scope while the brand keeps a single view across all of them. Without that combined view, the only complete picture of the campaign lives in a spreadsheet maintained by one internal person, which makes them a single point of failure whenever anyone needs a status update.
The brand should own it. The approval record is evidence of what was authorised and by whom, and it needs to outlast any individual supplier relationship. A brand-owned workflow also means the same process applies whether work is produced internally or externally, which makes it far easier to move a project between the two. Agencies should keep control of their own production process — how they resource, schedule and develop the work — but the brief, the milestones, the feedback, the approvals and the final assets belong in the brand's system.
Agency management software is generally built for agencies to run their own business: managing clients, tracking time, handling billing and monitoring profitability. Marketing project management software is built for the brand side, covering briefing, creative projects, resource visibility, proofing, approvals and campaign records. The distinction matters in a hybrid model because the brand needs a system it owns and can extend to partners, rather than relying on each agency's internal platform. The two can coexist — the agency runs its business in one, and participates in the brand's workflow in the other.
It depends entirely on where the record was held. If approvals lived in the agency's system, the history leaves with the agency. If they lived in email, it is technically retained and practically unusable. The record should sit with the brand, so that a question about an asset produced eighteen months ago does not depend on which supplier was engaged at the time. It also gives an incoming agency a reliable account of what was approved and why, rather than starting from a verbal handover.
