Most accountants see deposits in the bank and call it revenue. We do not. Inventory and COGS on accrual so your margins are real, sales-tax nexus handled before it becomes a liability, every Shopify, Amazon, and Stripe payout reconciled, and margin you can actually read by channel, from a licensed CPA who knows e-commerce.




Inventory you paid for but haven't sold, marketplace fees, refunds, ad spend, and sales tax in a dozen states: on a cash basis it all blurs together and your "profit" is fiction. We put inventory and COGS on accrual, reconcile every channel's payouts, and handle sales-tax nexus, so you finally know your real margin and where you owe.

Shopify, Amazon, Stripe, and PayPal payouts reconciled net of fees and refunds, all on one clean set of books.
Topline by channel and the cash to fund inventory, so growth never quietly runs you out of stock or money.
Economic nexus reviewed across states, registrations handled, and filings kept current, so an audit isn't a crisis.
Inventory and COGS on accrual with landed cost, so your margin is real and your taxable income is right.
Selling into Canada or overseas (GST/HST, duties, and international payouts) gets the cross-border treatment on top. See cross-border →
Most start with the return and a sales-tax review, then grow into monthly books and a CFO view as the brand scales across channels.
Just launched on Shopify? We set up the entity, the books, and sales-tax tracking so it is right from your first sale (formation & tax). Not sure which? A short call sorts it, we will tell you the one thing worth fixing first.
A Shopify brand had cash in the bank and assumed it was profitable. On accrual, with inventory and COGS done right, the real margin told a different and fixable story.
An Amazon seller had crossed economic-nexus thresholds in a dozen states without registering. We reviewed the exposure, registered where required, and got filings current.
A brand selling on Shopify, Amazon, and Stripe couldn't tie payouts to sales, so the books never matched the bank. We rebuilt the reconciliation channel by channel.
Client engagements of the firm. Details anonymized.
"On accrual, our 'profit' was smaller than the bank suggested, but at least it was real. We fixed our pricing and now we actually make money."

"They found we owed sales tax in eleven states and cleaned it up before any of them found us. That alone was worth it."

"Shopify, Amazon, and Stripe finally reconcile to the penny. I stopped guessing whether the books were even right."
