The verdict in three sentences
For a vegetable seed and young plant distributor serving greenhouse growers across the Westland and South Holland, the best option in 2026 is a B2B store with grower trade accounts, contract pricing and plant passport data on every relevant product, connected to your ERP. A general consumer SaaS can work for a small retail side, but it struggles with tiered grower pricing, lot traceability and pallet delivery slots. The ranking below starts from three year total cost and reversibility, so your catalogue and customer data stay yours when you change provider.
What the store must handle for a seed and plant distributor
A seed catalogue is technical. Each item combines a variety, a seed count or weight, coating or priming, a lot number and, for young plants and some seeds, plant passport details required under the EU Plant Health Regulation (EU) 2016/2031. Growers order by contract and by sowing schedule, often weeks ahead, and young plants are delivered on Danish trolleys or pallets to greenhouses in Naaldwijk, Honselersdijk or Westland villages within tight time windows.
| Requirement | Why it matters | 2026 ballpark |
|---|---|---|
| 400 to 2,000 SKUs | Varieties, seed counts, treatments | 4 to 8 weeks of content work |
| Grower trade accounts | Contract prices and volume tiers | Account approval and price lists per grower |
| Plant passport fields | Required on relevant plant material | Lot and passport data synced from the ERP |
| Pay on invoice and iDEAL | Growers pay on terms, small buyers pay now | Credit limits per account |
| Pallet and trolley delivery slots | Greenhouse logistics | Slot booking per postcode |
| Reorder from sowing plan | Repeat orders every season | Saved lists and scheduled orders |
The 2026 ranking
The ranking compares provider types and public software on stable criteria. Budgets are 2026 market ballparks for 400 to 2,000 SKUs and an 8 to 16 week launch; public software subscriptions vary by plan.
| Rank | Option | Three year total (ballpark) | Time to launch | Reversibility | Local support | Best for |
|---|---|---|---|---|---|---|
| 1 | B2B module of your ERP or an ERP centred stack (Odoo for example) | 40,000 to 120,000 EUR | 12 to 16 weeks | Medium to high | Good with a Dutch integrator | Distributors where lots and passports live in the ERP |
| 2 | Open source B2B store (Magento Open Source or WooCommerce) with a specialist agency | 30,000 to 100,000 EUR | 10 to 14 weeks | High, code and data are yours | Good | Complex pricing, own roadmap |
| 3 | Hosted SaaS with B2B features (Shopify for example) | Monthly subscription, public price varies by plan, plus apps and build | 6 to 10 weeks | Medium | Through partners | Mixed retail and trade, fast launch |
| 4 | Custom B2B portal | 60,000 to 150,000 EUR | 14 to 20 weeks | High if code is assigned | Good | Very specific ordering logic |
| 5 | Nearshore build on open source | Lower build cost, see below | 8 to 14 weeks | High | Remote with Dutch business hours overlap | Tight budget, clear scope |
| 6 | Industry marketplace or buying platform | Commission or fee | Immediate | Low | Varies | Extra reach only |
The ERP route ranks first because plant passport and lot data must be right, and the safest source is the system that already holds them. Open source ranks second on reversibility and freedom to model grower pricing. Hosted SaaS is fast but tiered contract pricing and delivery slots usually need paid apps.
Kolonell is one possible nearshore option. Kolonell's prices: Premium ecommerce site from 3,050 to 5,340 EUR (2,000,000 to 3,500,000 FCFA) in 21 to 30 business days, ecommerce option for 50 to 500 products at 760 EUR, and a medium application from 6,100 to 10,670 EUR for a grower portal with price lists and more than 500 SKUs. ERP connectors are scoped in the quote.
Mini case study
Illustrative example: Sanne, sales director at a seed and young plant distributor near Rotterdam, serves 350 growers. Her inside sales team handles 6,000 orders a year by phone and email, 12 minutes each, or 1,200 hours. With a B2B store she targets 60 % of orders online in year one, saving 720 hours at 40 EUR, or 28,800 EUR a year. If saved sowing plans lift reorders by 3 % on 12 million EUR of revenue, that adds 360,000 EUR of sales. An ERP centred store at 80,000 EUR over three years pays back within the first season.

FAQ
Do we need plant passport data in the online store?
Where a product requires a plant passport, the passport details travel with the goods, and showing lot and passport data in the account and on documents avoids errors. Sync them from the ERP rather than typing them into the store, across 400 or more SKUs.
Can growers keep paying on invoice?
Yes, B2B stores handle payment terms and credit limits per account, with iDEAL or cards for small buyers. Most distributors keep 80 % or more of trade revenue on invoice.
How long to put 1,000 SKUs online?
Plan 4 to 8 weeks for content, often longer than the build itself. Start with the 250 items that make 80 % of revenue.
How do delivery slots work for greenhouses?
The store offers slots by postcode and day, capped by trolley or pallet capacity per route. A grid of 3 to 5 delivery zones covers the Westland and surrounding area.
Should we build a mobile app?
Not at first: a fast responsive store covers 90 % of grower use. An app makes sense once growers reorder several times a week.
