Why the current way breaks

What this looks like on a normal Tuesday

When the internet goes down, our stores cannot ring up customers and lines form out the door.

Lost retail revenue and frustrated walk-outs.

What we build

Engineered capabilities, not generic templates

C-01

Offline-First Transaction Processing

Full local browser storage allowing continuous checkout, receipt printing, and cash drawer triggers with automatic background syncing upon reconnect.

Technical detail

IndexedDB client persistence, conflict-free replicated data types (CRDT).

Outcomes

Offline-capable

Store tills

Sales keep recording through an internet outage and sync afterwards.

Live

Stock and sales back to head office

No end-of-day upload.

We measure your baseline in discovery and report against it. No borrowed percentages.

Automation built in

Workflows that run on top of this module

Counter Sale → Real-Time Multi-Channel Stock Deduct

Sale completed at physical register immediately updates online e-commerce inventory to prevent accidental overselling.

  1. S1 · Trigger POS Receipt Finalized
  2. S2 · System Local Stock Deduct
  3. S3 · Action E-Commerce Channel Sync
  4. S4 · Notification Low Shelf Restock Notice
Event-driven trigger with retry queue · human sign-off where set

How a Point of Sale project runs, week by week

Open any stage to see what we do, what you receive and what we need from you.

We sit with the people doing the work and map how orders, stock and money actually move today, including the spreadsheets nobody mentions in the first meeting.

What happens

  • Process walk-throughs with key users
  • Inventory of every data source
  • Quantifying where time is lost

What you get

  • Current-state process map
  • Data source and quality audit
  • Scope baseline

What we need from you

  • Sample invoices, orders and spreadsheets
  • Two-hour interviews with each department lead

Risk handled

Critical spreadsheets that management does not know staff rely on.

We design the data model, roles, approval rules and integrations on paper before anything is configured.

What happens

  • Data model design
  • Chart of accounts review
  • Approval matrix design

What you get

  • Solution blueprint document
  • Role-by-role screen wireframes
  • Data dictionary

What we need from you

  • Sign-off on the chart of accounts and permission structure

Risk handled

Sales and warehouse asking for conflicting things mid-build.

We provision environments, configure the standard modules to the blueprint, and build any approved extensions.

What happens

  • Environment setup and hardening
  • Module configuration
  • Approved custom development

What you get

  • Working staging environment
  • Configured modules matching the blueprint

What we need from you

  • Tax settings, bank details and branding assets
  • Named admin users

Risk handled

Configuration drifting away from what was agreed in the blueprint.

We extract customers, vendors, products and balances from your current tools, remove duplicates and load trial datasets you can check.

What happens

  • Migration scripts
  • Duplicate detection
  • Trial balance reconciliation

What you get

  • Staging database loaded with cleaned data
  • Reconciliation sheet

What we need from you

  • Decisions on flagged duplicates
  • Lists of inactive products and customers to archive

Risk handled

Bad legacy data being carried into the new system on day one.

We connect the system to the tools that stay: banks, e-commerce stores, payroll, shipping and anything else agreed in the blueprint.

What happens

  • API and webhook connectors
  • Error handling and retries
  • End-to-end integration tests

What you get

  • Tested integrations in staging
  • Integration runbook

What we need from you

  • API credentials and vendor contacts for connected systems

Risk handled

Silent sync failures that nobody notices until month-end.

Your staff test real scenarios in staging and learn the system role by role, with recorded guides they can return to.

What happens

  • Role-based training sessions
  • Scenario testing
  • Fix sprints on UAT findings

What you get

  • Signed UAT test matrix
  • Recorded training library

What we need from you

  • Key users available about four hours a week for testing

Risk handled

Staff meeting the system for the first time on go-live day.

We freeze the old system, move the final changes across, verify opening balances and switch over, usually across a weekend.

What happens

  • Final delta migration
  • Opening balance verification
  • Hardware and scanner checks

What you get

  • Live production system
  • Signed cutover checklist

What we need from you

  • A data-entry freeze on the old system at an agreed time

Risk handled

Downtime during trading hours.

The team that built the system stays on it after go-live: fixing issues on the day they surface, adjusting screens staff struggle with, and sitting with finance through the first month-end close.

What happens

  • Daily check-in with your project lead
  • Same-day fixes and small adjustments
  • First month-end close support

What you get

  • Hypercare issue log with resolutions
  • First month-end close sign-off

What we need from you

  • A 15-minute daily call with your project lead
  • Staff reporting problems as they happen, not at the end of the week

Risk handled

Early friction pushing staff back to the old spreadsheets.

With clean data in one system, we automate the repetitive work around it: invoice capture, reorder drafts, approval routing and alerts.

What happens

  • Automation opportunity review
  • Workflow and agent build
  • Monitoring and tuning

What you get

  • Live automation workflows
  • Monthly report of hours recovered

What we need from you

  • A ranked list of the bottlenecks you want gone next

Risk handled

The new system settling into a passive record-keeping tool.
