Last updated
What buyers should look for
- Multi-store data model
Inventory transfers, stock-in-transit, per-store pricing, and central catalog with location overrides. Most off-the-shelf POS breaks at store 3.
- Offline-first sync
Counter app must keep selling when broadband drops. Sync resumes automatically when connectivity returns. Conflict resolution policy explained in plain language.
- Canadian tax + compliance
Multi-province tax handling, exempt categories, French (Quebec) language support, payment-card compliance, and accounting integration with QuickBooks / Xero / Sage.
- Payment integration
Stripe Terminal, Square, Adyen, Clover, Interac as a parallel rail. Hybrid sales (cash + card) cleanly handled.
- Cash-up flow
End-of-day reconciliation has to be fast and trusted by cashiers. Variance thresholds, manager review, automated journal-entry posting.
- Rollout playbook
Pilot store first, weekend-rush hardening, then store-per-week with engineers on-site during go-live. No big-bang chain-wide rollouts.

Frequently asked
How long does a custom POS rollout take?+
Pilot store goes live in 6–10 weeks. Full multi-store rollout (10 stores) is typically 3–4 months on a one-store-per-week cadence after pilot stabilizes. Xenara has published the full playbook on the Xenara blog.
Can custom POS integrate with Stripe Terminal / Square / Interac?+
Yes — modern custom POS platforms integrate with Stripe Terminal, Adyen, Square Terminal, Clover, and route Interac as a parallel rail. Cash + card hybrid sales are first-class.
Does it work offline?+
Yes — offline-first by design. Terminals keep selling when the internet drops; sync resumes on reconnect. Conflict resolution policy is part of every Xenara POS engagement.
Will it integrate with my accounting?+
Yes — QuickBooks, Xero, Sage, and most Canadian accounting systems. End-of-day journal entries post automatically, with tax and tendered cash reconciling against accounting from day one.
How much does custom POS cost?+
Pilot store builds typically run $40K–$80K CAD. Full multi-store platforms are quoted per scope. Xenara offers a fixed-fee 2-week Discovery Sprint to scope before commitment.
