Scaling Ecommerce from Garage to 3PL: When and How to Make the Move

When the garage becomes the problem#

Most ecommerce SMBs start with home fulfilment — the founder packing orders in the garage, basement, or spare bedroom. This is how Gymshark started. It's how Charlotte Tilbury's brand began. At low volumes (under 20 orders per day), it's an economical, flexible model. The problems begin when order volume exceeds the founder's personal packing capacity, when the home storage model creates inventory accuracy problems (stock in the garage, some in the kitchen, can't find the 3XL in black), when quality consistency suffers because packaging varies by whoever is packing, and when seasonal spikes (Christmas, Black Friday) completely overwhelm the home setup. Most ecommerce founders hit this point between 30 and 100 orders per day. At 50 orders per day at an average £45 order value, that's £820,000 in annual revenue — and the operational model hasn't changed since the business was doing £80,000. The mismatch is unsustainable.

The three fulfilment options between garage and 3PL#

Before committing to a 3PL, consider the intermediate options: (1) A small rented warehouse unit — typically 1,000-2,500 sq ft, £8,000-£20,000 per year. You handle all fulfilment in-house with hired pickers and packers. This works between 30-150 daily orders and gives you control over quality and cost. (2) A fulfilment centre that's part of an ecommerce platform — Amazon FBA is the most common, where Amazon holds your stock and fulfils orders for a fee (typically 15-30% of item price depending on size and category). The economics work best for standardised, non-fragile products with high volume. (3) A true 3PL (third-party logistics) provider — a specialist warehousing business that handles receiving, storage, picking, packing, and dispatch for a per-order fee. This is the most scalable option and the right one for brands that want to maintain their own fulfilment standards outside Amazon's ecosystem.

The 3PL economics: What you're actually paying#

A typical UK 3PL charges: inbound receiving fee (£0.15-£0.40 per unit received), monthly storage fee (£12-£25 per pallet or £0.20-£0.50 per cubic metre per week), pick and pack fee (£1.00-£2.50 per order depending on complexity and pack spec), materials (box, fill, tape) at cost plus a small margin, and outbound carrier cost (often negotiated by the 3PL at better rates than you'd get independently). On a typical ecommerce SMB order of 2 items, packed to a standard spec, the 3PL fee excluding delivery is £1.80-£3.50 per order. For a business shipping 100 orders per day (£65 average order value), that's £54,000-£105,000 in annual 3PL fees — compared with the staff cost of in-house fulfilment at the same volume (typically £35,000-£55,000 including manager). The 3PL premium is real — but it buys flexibility (scale up for Black Friday without hiring), professional infrastructure, and often better carrier rates.

Choosing a 3PL: The five questions that matter#

Not all 3PLs are the same. Ask these before you commit: (1) What is your average pick accuracy rate? Acceptable is 99.5%+. Below this, you're picking up the cost of mis-picks in customer service and returns. (2) What is your technology stack? You need real-time inventory visibility through a WMS (warehouse management system) that integrates with your ecommerce platform (Shopify, WooCommerce). (3) What is your SLA for same-day dispatch? Orders received by 2pm should ship same day — anything less than this is a customer service liability. (4) How do you handle returns? Returns processing should be included in the per-order fee or charged at a transparent flat rate. (5) What are the exit terms? You need to be able to exit within 30-90 days if the relationship doesn't work — not locked into a 3-year contract with punitive early exit fees.

Inventory accuracy: The transition risk most brands don't plan for#

The most common problem in the 3PL transition is inventory discrepancy — your ERP or POS shows 500 units of SKU-1147 in stock; the 3PL WMS shows 483 units. The gap is caused by receiving errors, damaged units not reported correctly, and the inherent inaccuracy of the stocktake at the point of transfer. Budget 1-2% of stock value for inventory shrinkage during the transition. Conduct a full stocktake immediately before transfer and reconcile against the 3PL's receiving confirmation within 48 hours of inbound. Set up your AskBiz inventory to pull from the 3PL's WMS in real time — this is the single most important integration in your ecommerce tech stack. If your website is selling stock that the 3PL no longer has in their system, you're creating oversell situations that generate customer complaints and emergency air freight.

The right moment to make the move#

The optimal 3PL transition point is when two of these three conditions are true: (1) You're fulfilling more than 50 orders per day consistently (not just at peak). (2) Fulfilment is consuming more than 30% of your or your team's working hours. (3) Your packaging quality or dispatch speed is generating customer complaints. Making the move earlier than this means you're paying fixed minimum fees for capacity you're not using — many 3PLs have monthly minimums of £500-£1,500 that can make them uneconomical at low volumes. Making the move later means your customer experience is already suffering — which affects reviews, repeat rates, and brand perception at exactly the moment your revenue is growing fastest.

AskBiz keeps your ecommerce data connected at every growth stage#

Whether you're packing in a garage or using a multi-site 3PL network, AskBiz keeps your inventory, sales, and financial data connected. When you're in the garage phase, AskBiz tracks your stock levels, average order values, and fulfilment performance in one dashboard. When you move to a 3PL, the integration with your WMS maintains inventory accuracy across both your ecommerce channels and your physical retail locations. And AskBiz's Xero integration means your 3PL invoices are reconciled against your shipped orders automatically — no manual line-by-line checking. Try it free at askbiz.co/signup.

• Moving ecommerce fulfilment from home to a third-party logistics provider (3PL) is a major operational transition.
• Do it too early and you pay for space you don't need.
• Do it too late and customer service suffers.
