RELEX Solutions vs Streamline (2026): which should you pick?

Pick RELEX Solutions if

• Fits if you run a large retail or wholesale chain with a planning team
• Makes sense if you want forecasting, replenishment and pricing from one vendor

Look elsewhere if

• Not for you if you are a small business, as it is aimed at enterprises
• Skip it if you want a price on the page, as none is published
• Watch out: confirm which of its many modules a quote covers
• Watch out: no free plan or trial is shown, only demos

Pick Streamline if

• Fits if you run a mid-sized maker or distributor and want orders written back to your ERP
• Works for teams that want forecasting and MRP in one tool

Look elsewhere if

• Skip it if you want a price on the page, as none is published
• Skip it if you are a small shop, since it is pitched at medium and large firms
• Watch out: setup depends on connecting your source system by API, ODBC or files
• Watch out: no free plan or trial is shown

RELEX Solutions

• No price is published; the site's call to action is to request a demo.
• It is positioned at enterprises, so a small business is unlikely to be its target buyer.
• The platform spans many modules, so a buyer should confirm which ones a quote covers.

Streamline

• No price is published: the pricing page asks buyers to share details so a specialist can reply.
• The platform is pitched at medium and large enterprises, so a small shop may find it more than it needs.
• Data connects by API, ODBC, spreadsheet or database, so setup depends on the customer's source system.
