How to Price Warehouse Start-Up Costs: Mobilisation, Ramp-Up and Amortisation

Most 3PL tenders price the steady state well and the first ninety days badly. The project team, the early-start manager, the recruitment campaign, the half-speed picking team in week two — these costs are real, they land before the first invoice goes out, and they are routinely guessed as a single lump sum or forgotten entirely. Here is how to build them up properly.

Why start-up costs get mispriced

A warehouse contract has two cost phases. The steady state — rent, labour, equipment, overheads — is what most of the pricing effort goes into. The mobilisation phase is everything it takes to get there: hiring and inducting a team, standing up the site, running the project, and absorbing the productivity dip while a new workforce learns the operation.

The steady state is priced from volumes and productivity rates. Mobilisation is priced from a staffing plan — who is involved, for how many weeks, at what weekly cost. When that plan is replaced by a single "implementation fee" guess, two things happen: the number is indefensible when the customer challenges it, and the items that scale with the deal (recruitment scales with headcount, ramp-up scales with team size) don't move when the deal changes.

The five kinds of start-up cost

Almost every line in a warehouse mobilisation budget falls into one of five categories:

• Project team — the implementation manager, solution designer and HR lead who run the start-up. Costed as weekly rate × weeks.
• Early-start operational staff — the site manager and supervisors who start before go-live to hire, train and set up. Their weekly cost should be inherited from the operational salary they will actually be paid (annual salary ÷ 52), not re-typed as a guess.
• Recruitment — medicals, police checks and advertising for the operational team. This one should be calculated, because it scales directly with headcount.
• Empty building — rent on the facility during the run-up weeks, if the lease starts before the revenue does. Often negotiated away with a rent-free fit-out period, so treat it as a toggle.
• Travel and other — accommodation and travel for the project team, plus anything deal-specific.

Recruitment: calculate it, don't guess it

Recruitment cost is a function of the team you are hiring — which the steady-state model has already worked out. A defensible build-up:

Cost per hire covers the per-person items (pre-employment medical around $350, police check around $40). Advertising is per role, not per person — one ad fills three picker positions. On a site with roughly 15.7 operational heads across 32 distinct roles, that is 15.7 × $391 + 32 × $300 ≈ $15,742. When the deal grows to two shifts, the number recalculates instead of staying frozen at the original guess.

Ramp-up: the cost nobody itemises

A new warehouse team does not pick at full rate in week one. Industry experience says a new operation starts somewhere between 60% and 80% of standard productivity and climbs to full speed over four to ten weeks, depending on the complexity of the operation. During that climb you are paying full wages for partial output — and the gap has to be covered with extra labour, typically casuals.

The extra labour cost of a straight-line ramp has a clean closed form:

Every line traces to a rate, a duration and a quantity. When the customer asks what the implementation fee covers, the answer is a table, not a shrug.

Amortised or upfront? Both — per line

The last decision is how the customer pays. There are two honest options, and the right answer is often different line by line:

• Upfront — the line is invoiced at the start of the contract, marked up with overhead and margin like any other cost.
• Amortised — the line is spread across the contract term inside the base warehouse cost. You are now financing the customer's start-up, so the annual charge should carry a financing cost — the same annuity (PMT) calculation used for funded assets:

Amortising the $11,594 site manager early-start over a 3-year term at 8.5% gives $11,594 × 0.3915 ≈ $4,539 per year — $13,618 over the term, of which roughly $2,024 is the financing cost of waiting three years for the money. Quoting $11,594 ÷ 3 = $3,865 per year is quietly giving the customer an interest-free loan.

Renewals: don't re-charge mobilisation

A continuing site being renewed does not get re-mobilised — the team exists, the racking is up, productivity is at standard. A renewal should carry near-zero start-up and no ramp-up on existing sites. But a new site added during a renewal genuinely needs the full treatment: project team, recruitment, ramp-up, all of it. Pricing both correctly in the same contract is exactly the kind of detail that separates a defensible quote from a copy-paste one.

The principle

Start-up pricing is a staffing plan with rates attached, not a round number. Build it from the five categories, calculate what can be calculated, put ramp-up in the months where it really lands, and charge a financing cost when you spread payment over the term. The first ninety days stop being a margin lottery.
