Fulfillment center vs. own warehouse — the real numbers for a successful online store
Real figures with public sources and verifiable links, transparent math, no marketing fluff. We put every euro you'll pay if you build your own warehouse on the table — and compare it with the outsourced option. You decide.
You've hit 10,000 orders per month. Congratulations — that's the threshold where logistics can no longer be run from the garage or the back of the shop. You have to make a major decision: do you build your own warehouse with an in-house team, or do you outsource everything to a fulfillment center?
It's a high-stakes decision and one that's hard to reverse. Once you've signed a 5-year lease, bought the racking, trained the people and integrated a WMS, changing direction costs time, money and nerves. And the answer isn't obvious — because it depends on concrete numbers that nobody in the market puts together transparently.
This article is the honest analysis. Yes, we're a fulfillment company. But every figure below comes with a linked public source — Romania's National Institute of Statistics, BestJobs, the Colliers and Cushman & Wakefield reports, real equipment offers from eMAG, SmartScan, IT Genetics, real rental listings from OLX, Imobiliare.ro, publi24, Romimo. You get the math. The decision is yours.
The scenario: which store we're using as the example
The reference online store profile
To keep the figures comparable with your reality, we fix the parameters of a typical store that has reached the decision threshold:
This scenario is identical to the one in our previous article on the cost of fulfillment in Romania, so you can make the comparison directly. The model applies to any store with small products reaching 10,000+ orders per month — beauty, fashion, accessories, supplements, gadgets, stationery.
Complete breakdown
The real cost of an in-house warehouse — every euro, with a source
Below we walk through every cost category. For each one, we show you where the figure comes from, not just the final number. You'll notice we include the founder's time cost from the start — along with an explanation of why it has to be there in any serious financial analysis.
Staff — pickers, supervisor, overtime
For 10,000 orders/month you need at minimum 2 full-time pickers plus a supervisor/coordinator who handles stock receiving, returns, courier communication and day-to-day problems.
Average picker productivity, according to international benchmarks, is 30 orders/hour for simple single-item orders. At 168 working hours/month per FTE, two pickers produce capacity for ~10,000 orders — exactly your threshold, with no buffer for holidays, resignations or Black Friday.
Real salaries, based on BestJobs and INS data for 2025-2026: an experienced warehouse operator reaches €700-900 net/month. With the 2.25% labour insurance contribution (CAM) and meal vouchers (840 RON), the total employer cost climbs to ~€1,250/month per picker. The supervisor (~€1,000 net) costs ~€1,700/month total.
Add Black Friday and holiday overtime (Romanian law mandates +75% per overtime hour worked) plus the natural staff turnover in logistics (30-40% annual turnover is typical in warehousing).

Warehouse rent and utilities
For 10,000 orders/month with 50 SKUs you realistically need ~200 sqm — receiving area, picking area, packing area, returns area, plus a small office. Less than that and it's operational chaos.
According to the Colliers Q4 2025 report, rent for Built-to-Suit prime space in modern industrial zones (CTPark, P3, MLP) is €4.5-5/sqm/month. For smaller spaces, class B/B+ warehouses in areas such as Pantelimon, Berceni, Drumul între Tarlale, Faur, real prices on OLX, Imobiliare.ro, publi24, Romimo and specialized real estate agency sites are €5.5-8/sqm/month. Realistic median for a warehouse suitable for a small-to-medium ecommerce business: €7/sqm.
Add utilities (three-phase power for the loading ramp, gas for winter heating, internet, water) — approximately €280/month — and administration/maintenance/cleaning — another ~€100.

The initial fit-out — the investment nobody calculates correctly
This is the category founders underestimate the most. A functional ecommerce warehouse for 10,000 orders/month requires professional equipment, not improvised solutions. Here's the realistic list with verifiable market prices:
- 3 professional barcode scanners (Zebra DS2278 or Honeywell Voyager 1470g, ~€700/unit) — €2,100
- 2 industrial thermal AWB printers (Zebra ZD230, TSC TE200 or equivalent, ~€600/unit) — €1,200
- 2 commercial scales (metrologically certified, up to 30 kg, ~€500/unit) — €1,000
- 3 ergonomic packing tables with consumables shelving (~€400/unit) — €1,200
- Complete industrial metal racking system for 200 sqm (angle-iron upright racking + crossbeams) — €8,500
- 3 picking carts with compartments (~€500/unit) — €1,500
- 1 manual pallet jack for pallet receiving — €800
- Security system (IP cameras, NVR, alarm, control panel) — €3,000
- 2 workstation PCs + monitors for the WMS — €1,500
- Miscellaneous (labelers, tools, tape dispensers, electrical installations, floor markings, ergonomic chairs, etc.) — €2,700
Total realistic initial investment: ~€23,500. Conservatively amortized over 24 months.

Professional WMS software with integrations
For 10,000 orders/month you need a serious WMS — not Excel, not a free plugin. You need bidirectional integration with Shopify/eMAG/WooCommerce/MerchantPro, mobile-terminal picking, location mapping, barcode scanning, accounting-grade reporting.
On the Romanian market, a professional WMS with all multi-channel integrations for a store doing 10,000+ orders/month realistically costs ~€1,000/month, whether as a cloud subscription or as a license with amortized maintenance and implementation.

Consumables — mailers, tape, labels
Bubble mailers, adhesive tape, thermal AWB labels, brand labels, bubble wrap, void fill — all of it costs money. For a store buying medium volumes (not industrial-scale): bubble mailer ~€0.18/unit, tape/labels/wrap ~€0.07/order. Realistic total: ~€0.25/order. A fulfillment center buying for dozens of clients simultaneously gets significantly lower prices — but you, as an individual store, don't access those prices.
Insurance — building, contents, liability
Building and contents insurance (for stored goods) starts at ~€80/month for a 200 sqm warehouse with average-value stock. Civil liability insurance for accidental damage — another ~€50/month.
Miscellaneous — maintenance, repairs, accounting, unforeseen costs
Costs that inevitably arise in a physical operation: shelving repairs, scanner replacements, security system maintenance, dedicated accounting for the logistics division, professional cleaning, pest control, electrical maintenance, occupational safety audits, etc. Combined, they reach ~€650/month.
The founder's time — a real cost, not a fictional one
When you have your own warehouse, you — the founder who should be creating business value — spend on average 2 hours every working day solving operational problems. Someone doesn't show up to work on Black Friday. The AWB isn't generating. The courier reports a damaged parcel. A picker resigned. The WMS made a stock error. And so on, every single day.
For a founder running a 10,000 orders/month store, 1 hour of their time is worth at least €50 in opportunity cost — because in that hour they could be doing strategy, marketing, new product development — things that multiply the business.
Why this figure is included from the start: it's a real cost, not a fictional one. The only way to eliminate it entirely is to hire a dedicated Operations Manager (which costs €2,500-3,500/month in total employer cost). You either pay with salary or with your time. No serious financial analyst ignores the opportunity cost of key decision-makers' time.
The total: what comes out at the end of the month
| Category | Monthly cost |
|---|---|
| Staff (2 pickers + 1 supervisor + overtime + turnover) | €4,770 |
| Rent 200 sqm + utilities + administration | €1,780 |
| Fit-out amortization (€23,500 / 24 months) | €980 |
| Professional WMS software | €1,000 |
| Consumables (mailers, tape, labels) | €2,500 |
| Insurance (building + liability) | €130 |
| Miscellaneous (maintenance + accounting + unforeseen) | €650 |
| Subtotal direct costs | €11,810 |
| + Founder's time (opportunity cost) | €3,000 |
| REAL MONTHLY TOTAL | ~€14,810/month |
Cost anatomy — €14,810 per month (founder's time included)
Real cost per order: €14,810 / 10,000 = ~€1.48/order. Or, if you temporarily strip out your time: €11,810 / 10,000 = ~€1.18/order on pure costs alone.
Direct comparison
The cost with Fast Fulfill for the same scenario
For the exact same 10,000 orders/month, with products that fit in a mailer, the cost breakdown with Fast Fulfill is transparent and published on our public pricing grid. The full calculation is in our previous article on fulfillment in Romania:
And — crucially — zero hours of your time spent on operational logistics.
The annual difference — in plain numbers
- Picker recruitment and retention
- Holidays, resignations, BF overtime
- Initial investment ~€23,500
- 5-year lease, hard to reverse
- 2 hours of your time, every day
- Zero recruitment, zero in-house team
- Zero initial investment
- Zero hours of your time, every day
- Pay exactly what you use
- Instant scalability as you grow
Monthly cost — visual comparison
Annual difference for 10,000 orders/month:
• Monthly cost, own warehouse (real, with founder): €14,810
• Monthly cost, Fast Fulfill: €8,000
• You save €6,810 / month × 12 = ~€81,700 / year
Plus elimination of the ~€23,500 initial investment and the fixed 5-year lease commitment.
For smaller volumes (1,000-5,000 orders/month), the difference becomes even more dramatic in favor of outsourcing — because most of the costs above (rent, WMS, supervisor, fit-out) are fixed and dilute poorly across small volumes. At 2,000 orders/month, the in-house cost per order shoots dramatically above €5/order, while Fast Fulfill stays below €1.10/order.
Why it's cheaper with us — the scale economy logic
It's not magic. We're more efficient because we share fixed costs across dozens of clients simultaneously. Here are the concrete mechanisms:
1. Fixed costs shared across many clients
Warehouse rent, WMS subscription, supervisor's salary, IT, logistics accounting, insurance — all of these cost roughly the same whether we process 10,000 or 100,000 orders per month. With dozens of active clients in the warehouse at the same time, each client pays a fraction of what they'd pay if they had to cover those costs alone.
2. Real volume on material purchasing
Bubble mailers, adhesive tape, thermal labels, bubble wrap — we buy everything at preferential prices negotiated at high volumes, directly from manufacturers under annual contracts. You, as an individual store, pay retail prices no matter how much you buy upfront.
3. Specialization — we do this every day, for years
Our operators run the same type of operation every day, with refined processes written into the WMS, tested across hundreds of thousands of orders. When you build from scratch, you pay the learning tax every single day.
4. Seasonality absorbed naturally
When you hit your Black Friday peak, other clients of ours are in the trough. Our team redistributes naturally onto the highest-volume clients, without us paying +75% overtime or panic-hiring temps in October.
5. Recruitment eliminated entirely
You no longer hunt for pickers in October. No more sick leave blocking production. No more resignations leaving you a person short on Wednesday. Our team is already there, trained, seasoned, redundantly covered.
Common myths — addressed head-on
"With my own warehouse I have better control over the goods."
Control means visibility, not physical possession. At a serious fulfillment center, you have a 24/7 client portal with a complete audit trail — you see every unit received, every order prepared, every return, in real time. Real control is often greater than what you get with an in-house team you can't supervise minute by minute.
"My margin is better without a logistics middleman."
The math above shows the exact opposite. Realistic in-house cost for 10,000 orders is €1.48/order (with founder's time) or €1.18 (pure costs only), versus €0.80/order with us. "No middleman" sounds good, but the real cost of going it alone is higher than the cost of collaborating at scale — up to the 30-50K orders/month threshold.
"I don't want to depend on someone else for deliveries."
Real dependency isn't on a partner with a written SLA and a clear 30-day notice contract. Real dependency is on pickers who quit without notice, on a courier you have a direct contract with who leaves you stuck with 500 parcels, on a WMS that crashes during Black Friday. With outsourced fulfillment, you have one point of contact, one SLA, one partner that's accountable.
When your own warehouse is the right choice
- Handmade products where the founder is involved in finishing or personalization. If every order requires 5-15 minutes of artistic handwork (engraving, custom assembly, painting, packing with a handwritten note), it can't be outsourced without losing the very thing that differentiates the product.
- Large B2B operations with pallets and their own distribution flow. If you deliver wholesale to retailers on pallets, with scheduled unloading windows at their warehouses, possibly using your own transport, the B2C fulfillment model doesn't apply.
- Luxury brand at very low volumes (under 500 orders/month). For a premium brand building the unboxing experience as a keepsake (engraved-logo box, silk paper, handwritten letter), at very low volumes simplifying the in-house process may be more efficient.
- Very high volumes — above 30,000-50,000 orders/month. At this threshold, you start to justify in-house economies of scale: you can afford a dedicated Operations Manager, an enterprise WMS, a team with real specialization, possibly partial automation. Below this threshold, outsourcing almost always beats the in-house solution on the math.

At what order volume does running your own warehouse start to make sense?
The realistic threshold is in the 30,000-50,000 orders/month range, when you can afford a dedicated Operations Manager (who takes over the founder's role in logistics, ~€2,500-3,500/month), and fixed costs dilute across enough orders. Below 30,000 orders/month, outsourcing almost always wins the math battle against the in-house solution — at 2,000 orders/month the in-house cost per order climbs above €5.
Why is the founder's time included in the calculation?
Because it's a real cost, not a fictional one. The founder who spends 2 hours/day on operational logistics problems loses those hours from strategy, marketing, product development. The only way to fully eliminate this cost is to hire a dedicated Operations Manager (who costs €2,500-3,500/month total employer cost). You either pay with salary or with your time.
How much does a warehouse picker realistically cost in Romania in 2026?
For an experienced warehouse operator with a net salary of €700-900/month, the total employer cost (gross salary + 2.25% CAM labour insurance contribution + meal vouchers of 840 RON) is approximately €1,250-1,470/month. For a supervisor/coordinator on €1,000 net, the total cost reaches ~€1,700/month. Add 30-40% typical annual turnover in warehousing, Black Friday overtime at +75%, and recruitment costs of €1,500 per replacement.
How many orders per hour can a picker process?
International industry median: 35 orders/hour (Rebus 2026 benchmarking). Ecommerce with a good WMS and optimized layout: 60-100 picks/hour (Productiv 2025). For a small ecommerce warehouse without sophisticated automation, realistically: 25-40 orders/hour for simple single-item orders. For our calculation we used 30 orders/hour — a conservative number, supported by the specialist literature.
How much does it cost to rent a logistics warehouse in Bucharest in 2026?
Built-to-Suit prime in modern industrial zones (CTPark, P3, MLP): €4.5-5/sqm/month (Colliers 2025 report). Smaller spaces (under 500 sqm), class B/B+ warehouses in areas like Pantelimon, Berceni, Drumul între Tarlale, Faur: €5.5-8/sqm/month (listings on OLX, Imobiliare.ro, publi24, Romimo, real estate agencies). For a 200 sqm ecommerce warehouse, the realistic median is €7/sqm = €1,400/month in rent + ~€280 utilities + €100 administration.
