Why a standard ERP does not work for you

And what we do instead.

Off-the-shelf ERP
  • Off-the-shelf ERP (SAP, Dynamics) costs €500–2,000/mo in licenses
  • You bend your business to fit the software, not the other way around
  • Months-long rollouts and expensive consultants
  • Your data is locked in with the vendor
Custom ERP by Saitami
  • One-time investment from €2,000 — no monthly licenses
  • We design the modules around your real workflow
  • Live in 1–3 months, a demo every 2 weeks
  • You own the code and the data forever
