Fractional vs Consultancy vs Agency vs Full-Time: How to Choose the Right Ecommerce Support

Short answer: The right support depends on two things: whether anyone senior already owns ecommerce strategy, and whether the gap is capacity or expertise. No senior owner and can't yet justify a full-time salary points to fractional. An existing team missing specific expertise points to consultancy, ongoing or project-based. Scaling one channel points to a specialist agency. Only once ecommerce is complex enough to need someone in the building full time does a permanent hire make sense.

What's the real difference between fractional and consultancy support?

Fractional

• Best for: Small, growing brands with no one senior yet owning ecommerce strategy
• How it works: Embeds as part-time senior leadership, owning strategy end-to-end
• Commitment: Ongoing, scoped to agreed hours or outcomes
• Why not a full-time hire instead: Not yet ready for the cost of a full-time senior salary

Consultancy

• Best for: Brands with an existing team that's missing specific expertise
• How it works: Provides expert direction and support alongside the existing team, without taking over ownership
• Commitment: Ongoing or project-based, depending on the need
• Why not a full-time hire instead: Doesn't need a new senior hire, just the expertise to unlock the next stage

What should actually drive the decision?

• Revenue stage: Pre-revenue or early traction vs established and scaling vs multi-channel at volume
• Operational complexity: Single channel and simple fulfilment vs multiple channels, markets, or a growing team to coordinate
• Nature of the gap: No one senior owns strategy at all, vs a team that owns it but is missing specific expertise

Fractional, consultancy, agency, or full-time: which fits?

• No one senior owns ecommerce strategy yet, can't yet justify a full-time salary: Fractional Head of Ecommerce, embeds and owns strategy end-to-end
• Team is in place but lacks the expertise to reach the next level: Consultancy, ongoing or project-based
• One channel needs to scale fast, such as paid media: Specialist agency, ideally directed by fractional or consultancy support so it stays aligned to overall strategy
• Ecommerce is now core to the business, multi-channel, high volume: Permanent full-time executive hire; the role has grown past what fractional or consultancy support should carry long-term

Transitional situations that call for fractional or consultancy support

• Launch: usually fractional; needs senior direction from day one on an ongoing basis, and there's no team yet to advise.
• Restructure: fractional as a bridge for continuity while a full-time replacement is found.
• Rapid scaling: fractional if there's still no senior owner; project or ongoing consultancy if the team already exists but is out of its depth.
• A specific initiative, such as a relaunch, entering a new channel, or an underperforming CRO programme: project-based consultancy.
• Bridge to full-time: the brand knows it will hire a permanent exec eventually, but needs the role covered, and the hiring process actually informed by someone who has done the job, in the meantime.
