Affordable Shopify App for B2B/B2C Inventory Segmentation
A focused Shopify app that enables non-Plus merchants to segment inventory by customer tags — showing and selling only the appropriate stock pool to each customer type. The app fills the gap between expensive enterprise solutions and clunky manual workarounds, targeting the large population of small-to-medium merchants running both wholesale and direct-to-consumer channels on a single Shopify store.
Why this matters
You run a growing Shopify store serving both wholesale and direct-to-consumer customers. Your wholesale buyers place large orders that need guaranteed fulfillment, but your DTC customers can accidentally drain the same stock pool, forcing you to cancel or delay B2B orders — damaging critical relationships. Shopify Plus would solve this, but at $2,000+ per month it is far beyond your budget. Existing apps feel overpriced for what is essentially one feature. The workaround of creating duplicate SKUs breaks your ability to manage products, draft orders, and purchase orders as unified items. You need a simple, affordable way to say: B2B customers see and buy from this inventory pool, DTC customers see and buy from that one — all on a single store without Plus.
- · Built for Small-to-medium Shopify merchants (on Standard or Advanced plans, not Plus) who sell to both B2B/wholesale and B2C/DTC customers on a single store and need to reserve or separate inventory pools by customer segment.
- · Most likely monetization: SaaS subscription with tiered pricing based on order volume or number of inventory segments.

MVP Scope · 1–2 weeks
- Set up Shopify Partner account and create a development store with B2B and DTC customer tags, two inventory locations, and sample products
- Build a backend service using Shopify Admin API that reads customer tags and maps them to permitted inventory locations via a metaobject configuration
- Create a Theme App Extension that intercepts product page inventory display and shows only the tag-appropriate location's stock count
- Implement a basic admin settings panel using Shopify App Bridge where merchants configure which customer tags map to which locations
- Write and run integration tests verifying that a B2B-tagged customer sees different stock than an untagged DTC visitor
- Implement Shopify Functions cart validation that blocks checkout when a customer attempts to purchase more than their assigned location's available stock
- Add purchase quantity cap configuration per customer segment to preserve stock for priority channels
- Build a unified admin dashboard showing combined and per-segment inventory across all products in one view
- Add support for draft orders by allowing admin to select which segment's inventory to draw from manually
- Package the app for Shopify App Store submission, write listing copy focused on the single pain point, and prepare screenshots showing before/after inventory separation
Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1Shopify's checkout on non-Plus plans may not provide sufficient extension points to enforce inventory pool restrictions at the critical moment of purchase — if a B2B customer can still check out using DTC stock, the core value proposition collapses
- 2Shopify could ship native customer-segment-based inventory allocation as a Standard plan feature within 12-18 months, especially as B2B commerce grows on the platform, making a third-party app redundant
- 3The target segment is explicitly price-sensitive and may churn to free workarounds (separate SKUs, manual monitoring) if the app cannot demonstrably prevent overselling in the first 30 days of use
Evidence Summary
How AI synthesized this insight — no verbatim quotes
Approximately 8 commenters in this discussion describe the same core problem: needing to separate or reserve inventory by customer segment without Shopify Plus. Multiple users explicitly state Plus is unaffordable and existing apps are overpriced for a single feature. Several describe failed workarounds — separate SKUs that break unified product management, and location-based flows that do not restrict what customers see at checkout. At least two commenters are actively pursuing custom development, and one has already implemented a variant of the separate-SKU approach for a client. The pain is acute, recurring, and currently unresolved by affordable off-the-shelf tools.
