StemmaAIFor businesses with heavy supplier spend, whatever you buy
Stemma checks every supplier invoice against your contracts and pricing history, flags the overcharges that slip through, and drafts the claim to reclaim them.
Free six-week pilot. You only pay if we find money.
~10 MNOKburned yearly
On every 1 bn NOK of supplier spend, around 10 MNOK leaks straight through.
>10,000hours yearly
On every 1 bn NOK of supplier spend, roughly 5 full-time roles vanish into admin.
Unit rates billed above your contracted tier.
Tiers that should have applied but did not.
Charges converted on the wrong basis.
Price rises beyond the agreed index (SSB/KPI) or cap.
Freight, energy, and add-on fees you never agreed.
The same line billed twice, even across separate invoices.
Link your ERP and contracts. Read-only, no engineering work, no rip-and-replace.
Every contract clause and every invoice line, parsed and checked as invoices arrive.
Breaches surface with the clause and the invoice line side by side, for your team to review.
Stemma drafts the recovery claim. You confirm it and send it to the supplier.
Stemma reads. Your team decides. You stay in control of every claim.
And more we connect to, not shown here. Stemma reads from your data and never writes back, so a new system connects in hours, not weeks.
After the pilot, we add up what it saves you and price from that, at a 6 to 8x return to you.
