What a finance function in this sector actually needs.
Inventory is bought before it is sold, which means every incremental dollar of growth consumes cash. It arrives as a sentence: we are growing sixty percent and we cannot make payroll.
We build stacked contribution margin — after shipping, after fees, after returns, after advertising — because that is the only margin that tells you whether an order was worth taking. Blended acquisition cost and blended marketing efficiency at the business level, not platform-attributed, so the same sale is counted once.
Profitability is rebuilt per item and per channel with marketplace commissions, fulfillment and storage penalties loaded in, and returns are run as a real line with a reserve against them rather than a surprise. Multi-channel settlement timing is reconciled properly, because each channel recognizes and pays differently.
Then the structural problem: inventory financing. Buying terms, turns, and the working capital facility modeled together, so growth is funded deliberately. Sales tax registration is mapped across every state and province where a threshold has been crossed — and Canada is heavier than most operators expect, because the provincial taxes are not all harmonized and each has its own rules.
What you can do afterwards that you cannot do now.
Know the contribution on an order before you spend to win it.
Fund growth without the inventory cycle eating it.
Register where you are actually obliged to, before a jurisdiction finds you.
Matched to the sector, not the postcode.
With a named controller alongside them, a named backup on every seat, and the specialist bench behind both — all inside one fixed monthly fee.
Nobody needs all of it at once.
The diagnostic decides which two or three matter first in your business, and you keep that assessment either way.
Your sector is one conversation away from a written answer. Start with what is actually going on.
One hour on your business, with the CFO who would hold the seat rather than a salesperson. Nothing to prepare and nothing to sign. A written note back within two working days saying what we heard and what we would look at first.
