Why we built
Produsera.
Produsera began as a CRM for one Dutch services company in 2025. Their work led to stock, purchasing and replenishment modules. Here is what exists today, how we build it and where the product is still young.
From CRM to inventory.
Produsera began in 2025 for IT'er aan Huis, a Dutch IT services company managing customers across spreadsheets and email. We built a CRM to keep customer records, appointments, quotes and invoices together.
Their next problem was inventory. Quotes became orders, orders needed stock, and stock needed suppliers and replenishment. Each new module came from work the team was already doing.
Today the same product offers a free CRM core and 13 optional modules for stock, purchasing, replenishment, returns and finance. It is still a young product, built from one real deployment and open to other teams with similar work.
Why existing software fell short.
I worked extensively with Odoo before building Produsera. It can get an ERP project moving quickly: define the data, add the logic and the interface takes shape. That speed is a real strength.
The harder part came when a business needed a workflow that did not fit the standard screens. A stock figure might need different rules for one warehouse, or a field might need to appear in a different place. Small changes became hours of tracing custom logic and overrides.
Produsera takes a narrower approach. Its CRM, inventory, purchasing and replenishment modules are built around those specific jobs. We can change a workflow without asking a customer to take on a full ERP rollout.
From one CRM to a modular product.
The product grew from one company's customer workflow into a CRM with inventory and purchasing modules. Here are the main steps.
- Autumn 2025
First build
A CRM for a Dutch services company to manage customers, appointments, quotes and invoices in one place.
- Through 2026
It became a product
Inventory, purchasing, replenishment, returns and accounting became optional modules as the customer needed them.
- Now
Open to the first workspaces
Teams can start with a free CRM for 2 users and choose from 13 paid modules as their work grows.
How we make product decisions.
The software fits the business
Custom fields, roles and module choice are configured in the browser, not quoted as a project. The point is the result, not the rebuild.
Honest beats impressive
This site names only modules you can actually open, and the sample figures on it are labelled as samples. If Produsera isn't a fit for you, the answer to your email will say so.
Nothing charges you by surprise
The 90-day programme takes no card. When it ends the paid modules lock rather than billing you €111 for a catalogue you may have opened twice.
Built to last, not to raise
Unfunded and not chasing scale. The plan is to make money shipping software that a handful of companies genuinely run on, and to still be here in ten years.
Work directly with the builders.
Produsera is a small remote team. Meetings happen on video, in English, with someone who can answer how the product works and what can change.
You talk to the people who build it
No account executives, no support tier that escalates to someone who has to go and ask. The reply to your email comes from the person who wrote the code it is about.
Fixes ship in days, not quarters
Small and unfunded cuts both ways: there is nobody to chase a bug for you, and nobody standing between the bug and the person who can fix it.
The roadmap is what partners ask for
That is the actual reason the first 10 workspaces are free. Access alone measures usage; a call every couple of weeks tells us what to build next.
