Flowlity vs Slimstock (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 Slimstock if

• Fits if you run a mid-sized or large distributor or retailer with a planning team
• Makes sense if you want one vendor for forecasting, replenishment and S&OP

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 that only counts stock
• Watch out: no free plan or trial is shown, only demos
• Not for you if you want self-serve sign-up

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.

Slimstock

• No pricing is published; the site directs buyers to book a demo or contact a local office.
• The platform covers far more than stock control, so it suits larger planning teams more than small shops.
• The vendor's pages are available in 11 languages and it lists offices in 28 countries.
