- 12-24 months, due to hardware device drivers, offline sync queues, and multi-location accounting edge cases.
ERP & Inventory
$1,500/mo/mo
- MVP
- 1 month
- Full replacement
- 12-18 months, due to low-latency mobile barcode scanner workflows, physical edge cases, offline resilience, and hardware integration.

our call
Start with Peoplevox — highest vibe code, weakest moat.
Erply
Erply controls the operational plumbing of retail: physical receipt printers, payment terminal bridges, offline sync queues, and matrix item variants. Building a basic web inventory list with AI is easy, but maintaining network-resilient register hardware integrations and complex FIFO inventory ledgers across physical locations is not feasible with prompt-generated software.
you can rebuild
- Product catalog management and matrix variant definitions
- Customer records and simple loyalty points tracking
- Basic manual stock adjustments and intra-warehouse transfer orders
- Web-based register UI for touch-screen product selection
- Standard sales dashboard reporting and inventory valuation metrics
what you lose
- Native local hardware wrappers for receipt printers, cash drawers, and barcode scanners
- Offline-first POS register state engine using local browser storage and sync queues
- EMV credit card reader direct integrations (Ingenico, Verifone, PAX)
- Fiscal memory cash register compliance modules for strict European tax jurisdictions
- Automated purchase order generation based on historic reorder points
real moats
- Hardware integration layer abstracting physical payment terminals and peripherals
- Operational switching costs associated with retraining retail floor staff across multiple locations
- Localized retail fiscal tax compliance and audit-trail engines
open source escape hatches
- ERPNext GPL-3.0
- Odoo Community LGPL-3.0
- Apache OFBiz Apache-2.0
Peoplevox
While modeling an inventory database with barcode fields takes hours, building a production-grade WMS requires sub-second mobile scanner responses, offline network resilience, local print agents, and zero-error inventory locking. Warehouse bugs physically halt fulfillment operations. Pay for battle-tested WMS software.
you can rebuild
- Web dashboard for stock inventory viewing and manual location assignments
- Purchase order receiving log and manual stock adjustment records
- Static PDF pick-list generation for basic order fulfillment
- Webhook triggers to push stock updates to Shopify or BigCommerce
- Supplier catalog database and basic low-stock threshold reporting
what you lose
- Optimized multi-item, batch-picking walk path algorithms for warehouse staff
- Native mobile scanner UI engineered for fast laser barcode scanning and vibration feedback
- Real-time bin location locking to eliminate double-allocations during high-volume sales
- Direct network hardware triggers for Zebra/EPL thermal shipping label printers
- Warehouse edge-case workflows (item damage tagging, partial pick fallbacks, item swaps)
real moats
- Extremely high switching costs tied to physical warehouse processes and worker muscle memory
- Deep hardware-level integration with rugged barcode scanners and thermal printers
- Mission-critical reliability requirements where software failure halts physical shipping
Questions people ask
Which is easier to rebuild with AI, Erply or Peoplevox?
Peoplevox. It scores 3/10 on vibe code with a moat of 4/10, so an AI-assisted MVP takes about 1 month and a full replacement about 12-18 months, due to low-latency mobile barcode scanner workflows, physical edge cases, offline resilience, and hardware integration..
Which one costs less, Erply or Peoplevox?
Erply at $450/mo/mo for a typical mid-market store. The gap between the two is about $12,600/mo a year.
