Packaged WMS software switches on in weeks and fits a standard warehouse well. It stops fitting when the floor runs on workarounds, the ERP or carrier you use is not on the connector list, or per-user fees grow with every hire. This page is written for operations leaders at distributors, 3PLs, and manufacturers with 50 to 500 people who have outgrown spreadsheets and packaged WMS tools. It lays out the decision factor by factor, with our published build bands beside each cost line.
Build a custom WMS when a package forces workarounds on the floor, the integrations you need are missing, or per-user fees across 30 or more floor users outgrow a one-time build. Buy a package when your pick-pack flows are standard, you run one site, and you need it live in weeks. A single-site custom build runs $30,000 to $64,000.
Last reviewed . Every figure on this page checked against our delivered-project records.
| Factor | Custom build with Rorix | Off-the-shelf WMS |
|---|---|---|
| Workflow fit | Built around how your floor actually receives, picks, packs, and ships. Exceptions become rules in the system rather than notes beside the scanner. | Configurable within the vendor's model. Flows the package did not anticipate become workarounds or change requests. |
| Integrations | Any system with an API or a file interface: your ERP, carriers, marketplaces, scanners, and the legacy tool nobody wants to replace yet. | Strong where a supported connector exists. Anything off the list means middleware, a partner, or a manual export. |
| Licensing model | One-time build with no per-user fees. Ongoing cost is hosting plus a maintenance retainer you size. | Per-user or per-site monthly subscription. The bill grows with every floor user and every added warehouse. |
| Code and data ownership | 100% of the source code and the database transfer to you. Host it anywhere and extend it with any team. | The vendor owns the platform and the roadmap. Your data is yours under the export terms in the contract. |
| Time to launch | Go-live in 8 to 12 weeks on our 5-phase process, with working software after every 2-week sprint. | Faster to switch on for a standard single site, often within weeks once configuration and data migration are done. |
| Scalability | Adding a site, a client, or a workflow is engineering work you commission, not a tier you upgrade to. | Scales within the vendor's tiers. New sites and modules are usually available, priced as additional licenses. |
| Customization cost | Priced as scoped work at published rates. Changes ship in sprints and become part of the code you own. | Configuration is included. Anything deeper depends on the vendor's roadmap or a paid customization from a partner. |
| Support model | A named technical lead during the build and a maintenance retainer after launch, sized to the system during scoping. | Vendor support tiers with published response times. Fixes ship on the vendor's release schedule. |
| Hardware (barcode and RFID) | Barcode scanning, RF-directed picking, and RFID readers integrated against the devices you already run on the floor. | Barcode support is standard. RF-directed workflows and RFID depend on the product and often on a higher tier. |
| Reporting | KPI dashboards built on the questions your supervisors and managers actually ask, with direct database access for anything new. | Standard reports and dashboards, with custom reporting through the vendor's tools or an export to your BI stack. |
Custom figures are our published build bands, derived from our team retainers and reviewed with every pricing change. The packaged column is left blank on purpose: vendors price per user, per site, and per module, and a range typed here would be stale before you read it.

| Line item | Custom build with Rorix | Off-the-shelf WMS |
|---|---|---|
| Single-site build with ERP integration | $30,000 to $64,000 one-time, you own the code. 3–5 developers, 3–4 months. | Vendor quote, verify before relying on it |
| Multi-site or RFID | $80,000 to $180,000+ one-time, you own the code. 5–10 developers, 5–6+ months. | Vendor quote, verify before relying on it |
| Years 2 to 5 | Maintenance retainer sized to the system. No license fees, no per-user fees, no per-site fees. | Vendor quote, verify before relying on it |
Go-live lands at 8 to 12 weeks inside each band; the band prices the full engagement, including stabilization and iteration after launch. A 30-minute scoping call turns the band into a written quote for your operation.
Fit as the vendors describe it. Pricing comes from their own pages and belongs in your written quote, not here.
Fits when: Companies already running NetSuite ERP who want warehousing inside the same suite, with one login and one data model.
Teams outgrow it when: When floor workflows or non-NetSuite systems need deeper integration than the module exposes.
Fits when: QuickBooks-centered small operations adding inventory control and basic warehouse tracking without leaving their accounting system.
Teams outgrow it when: Multi-site operations, high daily order volume, or custom picking logic beyond what an inventory-first product is positioned for.
Fits when: Multichannel product sellers who want inventory and order sync across marketplaces and storefronts in one SaaS.
Teams outgrow it when: Warehouse-floor execution depth: RF-directed picking, custom rules, and hardware integration beyond what a sales-channel-first platform positions itself for.
Discovery and assessment: we map your current warehouse operations, the workarounds, and every integration, and define the success metrics the build is measured against.
Design and configuration: a WMS design based on your workflows, with picking strategies, inventory rules, and integrations specified, and key screens prototyped for the floor to react to.
Development and integration: the WMS is built in 2-week sprints, integrated with your ERP, carriers, and sales channels, and connected to your barcode or RFID hardware.
Testing and parallel run: user acceptance testing, then the new system runs beside the package with every count and every order reconciled, while staff are trained and SOPs are written.
Go-live and support: a phased rollout by zone or by site, on-site support during launch week, and the package switched off only once the parallel run has matched for a full cycle.
Straight answers on cost, timeline, integrations, and ownership.
