WMS for Xero users: keep the ledger, fix the floor

Understand the decision

Search for "WMS that integrates with Xero" and you are really asking two questions: how do I get warehouse capability without giving up Xero, and how much system do I actually need? Confirm current subscription, allowances and implementation costs against an itemised proposal; the commercial structure is explained below. Xero's own guidance for businesses with real stock movement is to connect an inventory or warehouse system and let that system be the stock master, with Xero items set to untracked.

The field splits into three shapes. The classic Xero inventory add-ons, Unleashed and Cin7 Core (formerly DEAR Systems), with the quote-based Cin7 Omni above them, are inventory and order management platforms born in the Xero ecosystem: stock accuracy, purchasing, multichannel sales orders and B2B portals, with mobile barcode apps for pick, pack and putaway. Lighter tools like inFlow, Katana and Zoho Inventory cover simpler versions of the same job. Then there are operations platforms like OpsUI, where receiving and putaway, wave and zone picking, slotting optimisation, cycle counts, RF scanning and dispatch run as first-class modules on the same record set as orders, inventory and CRM, a platform built around the warehouse rather than a WMS app added to an inventory platform.

This guide is written by OpsUI, so read it knowing that, but the honest version of the advice cuts both ways. Plenty of Xero businesses do not need a WMS: if a small team can pick the day's orders from a list without falling behind, an add-on is cheaper, faster to connect and entirely sufficient. The trigger for more is when the floor becomes the constraint, pick rates, walking distance, mispicks, missed dispatch cut-offs, because directed workflows are what fix those. And credit where it is due: the add-ons have moved here, with Cin7 Core's WMS app documenting zone-assigned picking, directed picks by bin group and guided walk paths. The honest OpsUI differentiation is not that the add-ons cannot direct a pick. It is wave planning, velocity-based slotting optimisation and structured cycle-count programmes, plus orders, inventory, warehouse, dispatch and CRM on one record set, at public per-module pricing, with ANZ data residency, rather than a WMS app bolted onto an inventory core.

OpsUI's shape in this field: keep Xero as the ledger and run operations, orders, inventory, warehouse, dispatch, shipping, CRM, in a modular platform of 20 operational modules plus 5 integration connectors, with bidirectional Xero sync wired during rollout via the Finance & Accounting module. To be precise: that sync is configured with you during rollout, not a one-click Xero App Store install today, and we would rather you know that up front.

Local operating considerations

Confirm production, backup and log locations for the proposed deployment. Regional domains or billing currencies do not establish data residency. That local centre of gravity matters in practice: GST handling on both sides of the Tasman is table stakes rather than an afterthought, and support hours match your shifts. Two things still need checking on any shortlist. First, carriers: OpsUI has NZ Couriers live today, with Australia Post, StarTrack and other Australian carriers wired during rollout, whichever system you choose, confirm the specific carrier APIs you need are live, not roadmap. Confirm production, backup and log locations for the proposed deployment. Regional domains or billing currencies do not establish data residency.

Ask which carrier accounts, services and label formats are supported; how your accounting records move; and where production data, backups and logs are held. Record the answers for the exact deployment under consideration.

Compare the full operating cost.

Separate subscription cost from user allowances, integrations, devices, data preparation and onboarding. Ask who owns configuration, training, cutover and support, and which items are recurring.

A starting subscription price is not an implementation quote. Compare the same workflows, team size and transaction volumes across proposals. Keep the original currency, tax treatment and billing period visible.

OpsUI’s published package structure

Published monthly subscriptions in NZD. Existing annual pricing and package allowances apply. Additional seats are NZ$99 per month beyond the applicable allowance; integration connectors are separate add-ons.

A checklist you can use in a demonstration.

Bring representative records and ask each vendor to work through the same scenarios. Write down what was demonstrated, what needs configuration and what remains unverified.

1. Receive a discrepancy. Use an expected delivery with a missing line and damaged stock. Follow the difference through recording, review and the stock decision.
2. Allocate constrained stock. Use two orders competing for the same stock. Check reservations, priorities and what the service team sees.
3. Resolve a short pick. Start with an empty pick location. Show the exception, reassignment or backorder, and who can approve the next step.
4. Complete the dispatch handoff. Use your carrier, parcel mix and label format. Check tracking references, manifests and a rejected address.
5. Recover from an interrupted sync. Reject a record or interrupt delivery. Show visibility, retry behaviour, duplicate prevention and reconciliation.
6. Confirm access and reporting. Run the same scenario as an operator and supervisor. Check action permissions and the records available for investigation.

Fit and trade-offs

When a Xero inventory add-on is the better fit

Your pain is stock accuracy and channel sync, not floor workflow. If a small team can pick the day's orders from a printed or app list without falling behind, Unleashed or Cin7 Core solves the actual problem, reliable multichannel inventory above Xero, with less cost and less change. And if you need one step more than list picking, Cin7 Core's WMS app stretches to zone-assigned and directed picking without changing platforms.

You want a marketplace app connected this week. Unleashed and Cin7 are native Xero App Store integrations with years of maturity behind them; OpsUI's Xero sync is wired during rollout via the Finance & Accounting module, which is a configured step in a rollout, not a one-click install today.

You assemble or lightly manufacture. Unleashed and Cin7 Core both handle bills of materials and assembly natively, which suits food brands, fabricators and kit-builders that have outgrown Xero alone but do not need warehouse-directed workflows. (For heavy MRP and finite-capacity scheduling, look at dedicated manufacturing systems. That is not OpsUI's lane either.)

You sell hard across marketplaces and storefronts. Cin7's connector catalogue, it advertises 700+ platform connections, is far broader for ecommerce channel coverage than anything OpsUI publishes.

You are a 3PL billing clients for storage and fulfilment. Neither a Xero inventory add-on nor OpsUI leads there: purpose-built 3PL platforms like CartonCloud and Mintsoft handle per-client billing depth better today.

When you need a real WMS beside Xero

The bottleneck has moved from the spreadsheet to the floor. When pickers walk too far, mispicks creep up and dispatch cut-offs get missed, you need directed work, and you need it joined up. Cin7 Core's WMS app can direct a zone pick; where OpsUI goes deeper is wave planning, velocity-based slotting optimisation and structured rolling cycle-count programmes, run as modules of the same platform as your orders, dispatch and CRM.

You want operations breadth without a suite migration. Confirm current subscription, allowances and implementation costs against an itemised proposal; the commercial structure is explained below. All of it is published pricing.

Scope the required modules, users, data preparation and integrations before comparing delivery time or total cost. OpsUI was built from the floor by a founder with three years on it, ships a public weekly changelog, and rolls out module by module — the bidirectional Xero sync is wired during that rollout so the ledger keeps reconciling from day one.

Confirm production, backup and log locations for the proposed deployment. Regional domains or billing currencies do not establish data residency.
