Morsa publishes this guide. Morsa is software with an AI agent that works in your ERP, email and Teams; it keeps the supplier dates in your MRP true. Prices are the vendors’ own, read 8 November 2026.
Quick answer
Per user or per plan: only MRPeasy charges per user. The others sell plans with a set number of logins (and, at Cin7, yearly sales orders), so the login that crosses the plan’s user count is what pushes you up a tier.
Shopify and QuickBooks: MRPeasy, Katana, Fishbowl, Cin7 and inFlow all connect to both. Fishbowl Advanced charges $50 a month per store, and Cin7 counts Shopify as one of its included app integrations.
Do you need MRP at all? If you assemble simple kits to stock, inventory with bills of materials (BOMs) is enough. If you run work orders through routings, buy material against customer orders and send parts out for plating, you need MRP.

Worked cost: a 15-person maker
The shop: 15 people, 6 logins (owner, planner, buyer, sales, bookkeeper, shop lead), 200 SKUs, 60 BOMs, one building, 150 orders a month from wholesale accounts and its Shopify store, books in QuickBooks Online. It needs routings, lot tracking and outside processing such as plating.
Every total uses yearly billing, the cheapest way to pay (MRPeasy charges 11 months for 12). Three-year totals assume today’s prices and 6 users throughout.
System and plan | Why this plan | Year one, then three years |
|---|---|---|
MRPeasy Professional | Adds subcontracting and quality control over Starter; Shopify and QuickBooks included | 6 users x $69 x 11 months = $4,554; $13,662 |
Cin7 Core Pro | Standard caps at 5 users and sells MRP as an add-on | $6,589 paid yearly ($7,188 paid monthly); $19,767 |
inFlow Manufacturing Scale | Growth caps at 5 users; lot numbers are an add-on | $629 x 12 + $499 onboarding + $39 x 12 lot numbers = $8,515; $24,547 |
Fishbowl Advanced Manufacturing | Fishbowl Inventory has no MRP | From $675 x 12 + $50 x 12 Shopify = $8,700; from $26,100. A floor: the quote rises with users and deployment |
Katana Advantage | Free stops at 30 SKUs | Quote only |
Without subcontracting, MRPeasy Starter is 6 x $49 x 11 = $3,234 a year. Optional extras: inFlow’s $999 training package in place of the $499 one [6]; MRPeasy expert hours from $199 a month [1]. Leaving QuickBooks instead of adding to it? See moving from QuickBooks to an ERP.
A 2-warehouse ecommerce brand with 8 users and 3,000 orders a month: year one is about $6,487 on inFlow Inventory Pro, $8,748 on Fishbowl Inventory Scale and $13,189 on Cin7 Core Advanced, paid yearly.
Keeping supplier dates in the MRP true
Each system above plans from the PO dates typed into it, so a supplier slip nobody records makes the shortage report wrong. Morsa works next to whichever one you buy, or on QuickBooks and spreadsheets before you buy.
It asks suppliers to confirm every open PO date from the buyer’s own mailbox. The buyer approves each kind of message once; after that it runs under that rule.
When a reply moves a date, it updates the PO and shows which work orders and customer orders that hits.
The buyer picks the fix; notes to customers wait as drafts.
JRG Automotive, a Morsa customer, caught 5 of 8 production-stopping shortages early enough to act, about $2 million saved. Book a 30-minute walkthrough, or read the method in automating supplier follow-up on open POs.
