The 30-second answer
Fishbowl is the bigger, longer-established choice: more features out of the box, a long QuickBooks track record and a consistent product that works the same way for every customer, with little room for custom work. Convexity is smaller and younger and works more like a boutique: our founders and engineers set it up with you, adapt it to how you work, and put AI to work on your purchasing. Pick Fishbowl for breadth and a proven standard; pick Convexity for an autonomous purchasing manager and a team that builds around your process.

An autonomous purchasing manager, not another tool
Fishbowl gives you reorder points to set and maintain. Convexity’s inventory optimization works like an autonomous purchasing manager: every week it re-forecasts each SKU from its own sales history, resets reorder points and safety stock, and drafts purchase orders by vendor that respect lead times, minimums and case packs, with the reasoning shown. Your buyer reviews the exceptions and approves; the routine work is already done.
Why a home-furnishings brand chose Convexity over Fishbowl
In October 2026 a made-to-order home-furnishings brand with about 4,000 fabric SKUs signed with us after also evaluating Fishbowl. Orders reach them through WooCommerce, showroom reps, EDI from department stores and email, and 20 to 30% of their SKUs were regularly out of stock or late. They told us Convexity cost more than Fishbowl and chose it anyway, for four reasons:
The SKU-level inventory projections went further than what they saw from other vendors.
Every pillow, sofa and ottoman maps to the yardage of fabric it uses, so each sale draws down raw material automatically.
They work directly with our founders. One of them ran purchasing and inventory at Wayfair, a channel this brand sells through heavily.
We adapt the workflow to how their factory runs, now and later, instead of the other way round.
Can Convexity run alongside Fishbowl?
No. Convexity does not integrate with or operate on top of Fishbowl. It replaces the inventory, sales-order and purchasing work you run in Fishbowl today, and QuickBooks Online stays your accounting system.
