One system · your whole operation

Four modules.
One system.

No separate packages, no integration mess. One database, one login, one point of contact. Below is what your potato trading company runs on — shown with real screenshots.

Lot registration

Lot registration

Every lot gets a KB number and is tracked from purchase to delivery. Warehouse, bay, sampling, grading — always traceable.

View module →
Contract processor

Contract processor

Incoming contracts read in automatically and linked to the right lot — no retyping.

View module →
Crop protection

Crop protection

Record sprays and treatments per lot. Products, dosages and pre-harvest intervals — complete and auditable.

View module →
Forklift manager

Forklift manager

Record every stock movement straight from the forklift — scanned on tablet and handheld, visible at the office in real time and linked to the KB number.

foundation.
New sector.

PotatoManager runs on the same codebase as BulbManager — in production at 200+ companies since 2009. You're not getting a 1.0 experiment; you're getting a 17.0 system with a new face on it.

Proven technology

No experiment. A mature system that has proven itself for 17 years.

Built for practice

Frequently asked questions

Questions we
often get.

How does PotatoManager differ from BulbManager?
+
Same codebase, same reliability. The difference is in the configuration: potato-specific size gradings, variety names and sector standards, set up for the potato chain. You're not getting a "bulb product with a different logo" — you're getting an implementation set up for your sector, on a foundation that has been in production for 17 years.
Can I import my existing data?
+
Yes. During the configuration phase we import your existing lots, customers, growers and history. Excel, CSV and direct exports from most fresh-produce and trading packages are standard.
How long does implementation take?
+
On average 4 to 8 weeks. Demo, configuration, training, go-live. We work at your pace, not to a rigid schedule. For larger companies with multiple warehouses it can take a little longer; for smaller companies, shorter.
What does it cost?
+
It depends on company size and which modules you use. We're happy to give a concrete quote after a no-obligation demo — no hidden price list, no "from €…" tricks. Just a fair price for a fair product.
Is there on-site support?
+
Yes. We do training on-site as standard — for the office and for the warehouse. For service visits we drive from Zwaagdijk-Oost throughout the Netherlands. For customers across the border we work via remote support.
