Start with the core.
Bolt on the rest.
Produsera is a CRM you assemble. Customers, appointments, quotes and invoices are free forever. Stock, purchasing, replenishment, returns and accounting are separate modules — switch one on this month, switch it off the next.

The part you never pay for.
Customers, appointments and a dashboard over them — plus quoting, invoicing, notes and a full audit log. Unlimited records, up to 2 users, and no expiry date on the trial, because there isn't one.
Dashboard
Revenue, recent activity and what needs attention, on the screen you land on.
Customers
Contacts and accounts, with quotes, orders and invoices attached to each one.
Appointments
A shared calendar for visits, jobs and calls, kept against the customer record.
Team and roles
Invite people, set what each role can reach, and read the audit log for the rest.

The first 10 workspaces
get all of it, free.
Produsera is new and looking for its first real operators. Ten workspaces get the entire catalogue for 90 days in exchange for telling us the truth about it.
Slots go in signup order · No approval step
- What you get
- Every module unlocked, 5 users, 90 days
The whole catalogue is €111/month once the programme ends. During it you pay nothing and we never ask for a card.
- What we ask
- A call every couple of weeks
Tell us what broke, what you needed and what you went back to a spreadsheet for. That is the entire price.
- What happens after
- The core keeps running
On day 91 the paid modules lock. Nothing is deleted, nothing is charged automatically, and your CRM data stays open in front of you.
Fit what you run.
Each module is a separate part with its own price. Fit one and it appears in the workspace inside a minute. Remove it and billing stops at the end of the month — your data stays where it is.

It tells you what to buy.
You still decide.
A run projects availability forward across your lead times, finds what will fall short, and drafts the purchase orders that fix it. It changes no stock quantity and posts nothing — a suggestion you never approve costs you nothing.
- Target and safety stock per item, with per-supplier overrides
- MOQ, order multiple and lead time read from the supplier's own offer
- Runs are immutable — last month's decision is still auditable
