Cash versus accrual is a decision to set with your CPA, and it bites harder in ecommerce than in most businesses because inventory and payout timing pull the two methods apart. That choice is not ours to make, but it shapes how the file is kept and why the monthly close is worth doing properly.
On a pure cash basis, buying a large slug of inventory looks like an enormous expense the day you pay for it, and a payout that clears in the next month drags income across the period boundary — both of which distort margin badly for a seller carrying stock. Accrual, with inventory held as an asset and COGS matched to the sales that consumed it, usually gives a truer read of ecommerce profitability. Whichever basis your CPA elects, a real month-end close is what keeps the picture honest: every channel's payouts reconciled, inventory and COGS trued up, fees and refunds recorded, sales-tax liabilities separated. We keep those underlying records clean so your chosen basis sits on reconciled data, and we do not choose or change your accounting method — that stays with your accountant.
