Flowlity vs Streamline (2026): which should you pick?

Pick Flowlity if

• Fits if you are a mid-sized distributor or maker with an ERP and a stock planning problem
• Makes sense if you want forecasts that size safety stock

Look elsewhere if

• Skip it if you want a price on the page, as none is published
• Watch out: the trial's length and limits are not stated
• Watch out: a data feed to your ERP has to be set up first
• Too light for large store networks, by the vendor's own FAQ

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

Flowlity

• No prices are published and the vendor has no public pricing page; buyers book a demo.
• The vendor says the product connects to ERPs by API, SFTP or EDI, so a data feed has to be set up.
• Flowlity's own FAQ says it has less depth than RELEX in shelf-level merchandising for very large store networks.
• Some modules, such as assortment planning and the Co-Planner, are marked as new.

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.
