The operating model

Your finance department: the roles, the software, and how it all connects.

Most owners buy accounting software and wait for a finance function to appear. It doesn’t. A finance department is a set of roles, a set of systems, and a rhythm that ties them together — sitting inside the wider business, taking in what sales and operations produce, and handing back the numbers you make decisions with. This is the whole map, layer by layer.

What feeds it

The rest of your business

Sales, purchasing, payroll and your own decisions all arrive as transactions. Finance doesn’t create them — it catches them.

What it does

Five layers of software

Capture, ledger, money movement, treasury, and the close. Each one hands cleaner information to the next.

What comes back

Decisions you can defend

Pricing, hiring, tax, and a set of books a bank or a buyer will accept without an argument.

The map

One system, three zones.

Finance isn’t a department that sits off to the side. It sits in the middle of the flow — and every block below is a place where the flow either holds together or breaks.

Hover a block to light up what it touches. Select one to open what it does, who runs it, and the software behind it.

Zone 1 · The business feeds it

every decision and every dollar arrives as a transaction

Zone 2 · The finance department

a reviewed set of numbers goes back out

Zone 3 · It hands back

Those decisions change what the business does next — and the loop starts again.

Start anywhere

Pick a block above.

Each one opens here with what it does, what “running well” actually looks like, the software behind it, and how it fails when it’s neglected. If you’re not sure where to begin, start with Layer 2 — the core ledger. Everything else either feeds it or reads from it.

Take it with you

The whole map, on two printable pages.

The three zones, the five layers and the software behind each, where each one usually breaks, one month of cadence, and a build-order checklist with tick boxes. Print it, mark what you already have running, and bring it to the conversation.

The rhythm

Software doesn’t run a department. A cadence does.

The stack is only half of it. What separates a finance function from a pile of subscriptions is that the same things happen at the same time every week and every month, whether or not anyone feels like it. Here is one month of a well-run department.

Daily
Receipts captured at the till, bills forwarded as they arrive, the bank feed clearing itself into the ledger.
You & the bookkeeper
Weekly
Everything delivered gets invoiced. Receivables chased. Bills approved and the payment run released on its published day.
Office admin
Pay period
Payroll processed on the calendar, source deductions remitted against it, the liability cleared — not carried.
Payroll & admin
The close
Every balance sheet account reconciled, coding reviewed, accruals posted, prior period locked, reporting pack issued.
Bookkeeper → controller
daily habit scheduled event the close Scroll sideways on a narrow screen.

QUARTERLY

Sales tax filed, instalments checked, the tax reserve topped up, treasury reviewed — and an actual conversation about what the numbers are saying. Controller & CFO.

ANNUALLY

Year-end and the T2, compensation mix set, next year budgeted, and an honest look at whether the stack still fits the business. CFO & tax accountant.

Build order

You don’t need all of it. You need the next layer.

Buying the whole stack at once creates administration you don’t need and a system nobody uses. Each layer below solves a problem the one before it creates — add it when that problem actually shows up.

FIRST

Get the record right

Before anything else, and worth doing properly even if you never add another tool.

  • A business bank account that is only ever used for business
  • Xero or QBO, with every account on a live feed
  • Dext, submitted daily
  • A chart of accounts designed on purpose
NEXT

Get out of the payment loop

Add this when someone other than you is spending, or when paying bills has become an evening job.

  • Dext Payments — approve and pay where the bill was captured
  • A published weekly payment run
  • Plooto for pre-authorised debit and CRA payments
  • Loop, if you buy or sell in another currency
THEN

Add the review layer

Add this the moment the numbers start driving real decisions — hiring, borrowing, pricing.

  • A close calendar with a date on it
  • Controller review before anything is used
  • The same reporting pack every month
  • A funded, untouchable tax reserve
LATER

Put the surplus to work

Add this once there is genuinely idle cash and the three layers above it are running without you.

  • Treasury accounts, split by purpose
  • A quarterly CFO cadence
  • KPIs tied to your real drivers
  • Planning that runs further out than year-end

Not sure which layer you’re on? The five stages of the client journey maps this against where the business itself is.

Common questions

The things owners actually ask.

Do I need all of this software to run a small business?

No. A ledger and a capture tool cover most businesses under about half a million in revenue. The rest gets added when a specific problem appears: an approval layer when someone other than you starts spending, multi-currency banking when you have foreign customers or suppliers, treasury when there is genuinely idle cash. Buying the whole stack early creates admin you don’t need.

Xero or QuickBooks Online — which is better for a Canadian business?

Both are capable. We prefer Xero for its bank reconciliation workflow, its app ecosystem and its multi-currency handling, and it’s what we standardise on for new files. QuickBooks Online is very widely used in Canada and is a fine choice, particularly where an existing bookkeeper or payroll workflow is already built around it. The larger risk is not the platform — it’s a chart of accounts that was never designed for the decisions you actually make.

Dext Payments or Plooto — do I need both?

They overlap on paying suppliers and differ everywhere else. If your bills already arrive through Dext, Dext Payments removes a handoff entirely: the invoice is captured, approved and paid without leaving the platform. Plooto earns its place on the receivables side — pre-authorised debit for collecting from recurring customers — and for CRA payments. Many businesses run both, and there is no prize for using fewer tools than the job needs.

How often should I submit receipts?

Daily, at the point of purchase. A receipt photographed at the till takes about ten seconds and still carries the context of what it was for. The same receipt found in a glovebox five months later takes ten minutes and an email exchange, and often ends up coded to a guess. Capture discipline is the single cheapest improvement most businesses can make to their books.

Does the Canada Revenue Agency accept photographed receipts?

The CRA requires business books and records to be kept for six years from the end of the last tax year they relate to, and electronic records must be kept in an electronically readable format and be accessible on request. An image stored against the transaction in your accounting system satisfies the readability and accessibility part, which is what makes a review go smoothly. Before destroying paper originals, confirm your imaging process meets the CRA’s electronic record keeping requirements.

Should my corporation invest its surplus cash?

Sometimes, but the tax treatment matters. Investment income earned inside a Canadian-controlled private corporation is taxed differently from active business income, and passive investment income above $50,000 in a year begins to grind down access to the small business deduction. Money owed to the CRA in the next ninety days should not carry market risk at all. Decide the purpose of each pool of cash before deciding where it sits — our passive income calculator is a reasonable place to start.

What’s the difference between a bookkeeper, a controller and a CFO?

A bookkeeper records what happened and reconciles it. A controller is accountable for whether the record is right — the systems, the close, and compliance. A CFO or advisor uses that record to decide what happens next. In a small business one person often wears more than one of these hats, but the three jobs are genuinely different, and skipping the controller layer is what allows errors to travel into decisions. The bookkeeping process walks through all four roles in detail.

On the software we name. These are the tools we use on real client files, chosen because they work well together — not because of any commercial arrangement. Some vendors operate partner or referral programmes for accounting firms, and we may participate in or receive a benefit from one or more of them. It doesn’t change what we recommend, and we’re happy to tell you exactly where we stand on any tool listed here if you ask. Pricing, features and country availability all change; check the vendor’s own site before you commit.
A conversation starter, not advice. This page describes a general operating model. Your situation — your structure, your industry, your obligations — will change what the right answer looks like. Nothing here is accounting, tax, or investment advice, and it isn’t a substitute for a conversation about your specific circumstances.
One team, one system

Let’s look at what you’ve already got.

Most businesses we meet already own three of these five layers — they just aren’t connected, and nobody is reviewing the output. A short conversation is usually enough to see which layer is missing and what it would take to close the gap.
