Eight modules, one loop,
one source of data
Sales, purchasing, inventory and costing form the operations loop; bookkeeping, payroll, tax and reporting follow along. Every module comes from systems we already run, then is tailored to your process.
Operations loop
Sales→Purchasing→Inventory→Costing
Each transaction happens once; documents, inventory and cost follow it all the way — no copying between systems and Excel.
Books & compliance
Bookkeeping·Payroll·Tax·Reporting
Every transaction posts automatically; payroll, sales tax and reports all come from the same data.

AI INSIDE
Ask anything, move faster,
people confirm every step
AI drafts, people confirmEvery write is shown to a person first.
Ask in plain language
Ask about balances, aging, margins, inventory or the story behind any document; answers cite their source and open to the detail.
Automation: let the system do the repetitive work
Invoice recognition, bank-feed classification, month-end checks and recurring monthly entries — drafted by the system.
AI assistant: work in a conversation
Connects directly to AI assistants such as Claude, so staff can look up the books, enter documents and run month-end in a conversation — with per-person permissions on what they can do and which company they can see.
CASE STUDY
A mid-sized manufacturer:
from three data silos to one system
Books in QuickBooks, inventory in SOS Inventory, costing in dozens of Excel files — the same shipment showed three different numbers in three places.
- Anonymized
- Mid-sized manufacturer
- Imported materials · multi-currency
- Multi-step costing

One system, one source
- Operations, inventory, costing and books connected
- Subledgers tie to the GL every month
- Click any number on a report to see its documents

Month-end flowTheir own month-end steps, one node each: colour shows data status, a tick means a person confirmed it, and a click opens that step.

Accountants and IT together:
fewer detours than traditional custom builds
Big ERP systems cost too much, off-the-shelf software can't fit your process, and with a traditional custom build you often find the books don't tie only after go-live. With accountants and IT working together, the books, tax and costing are designed right from the start.
| Traditional custom build | EasyONE: CPA × IT | |
|---|---|---|
| Are the books right? | — Developers rarely know accounting; mismatched reports surface after go-live | ✓How each transaction posts is decided before development; subledgers checked against the GL every month |
| Tax compliance | — Sales tax and payroll deductions are yours to verify | ✓GST/HST, payroll deduction and corporate tax rules are built into the system from design |
| Data migration | — Often quoted separately, or left to you | ✓Opening balances and history — we migrate them; old and new run in parallel until they tie |
| Data security | — Security is often patched in later; permissions and audit trails are incomplete | ✓The architecture & security team is involved from the design stage: tiered permissions, full audit trail, data kept in Canada |
| Fees | — Billed by the hour; every change costs more | ✓Diagnosis before quote, with several pricing options |
“Traditional custom development” means the common approach where only a software vendor builds to your spec. Practices vary; this is a general comparison.

HOW WE WORK
Tailored to your process,
we migrate, run in parallel, then switch
Two things make switching systems scary: data that won't move, and numbers that don't tie. We own both from day one.
1
Process diagnosis
CPA + IT together
We map your process from order to financial statements and flag the most manual, error-prone steps.
2
Tailored build
you see every step
Start from proven modules and build only what's unique to you; adjust as you use it — not a black box delivered all at once.
3
Full data migration
We do it
Opening balances, history, item master, customers and vendors, open documents — imported from your old system and Excel, then tied out line by line.
4
Parallel run
Switch only when it ties
Old and new run side by side, reconciled account by account each month, every difference traced; you switch when you're satisfied.
5
Go-live & support
Ongoing support
Month-end support and staff training; accountants and IT stay with you, adding features as needs change.
We learn your needs first, then give you several pricing options
Mix and match modules
Sales, purchasing, inventory, costing, bookkeeping, payroll, tax, reporting — pick only what you use; never pay for features you don't need.
Go live in phases
Start with the biggest pain point, add the next once it runs smoothly; each phase is quoted separately.
Flexible payment
Implementation fee + monthly fee, or pay by phase — agreed together after the diagnosis.
Support included monthly
Hosting, maintenance, updates and ongoing support from accountants and IT are all in the monthly fee.
Pricing depends on modules, data volume and customization; you get a written quote after the diagnosis, based on the plan we both confirm.
