How CoreOps works

Ecommerce headaches

Why generic accounting does not work for ecommerce.

Selling online introduces layers of financial complexity that traditional bookkeeping was never designed to handle. Between marketplace fees, multi-currency settlements, inventory valuation, and advertising costs, ecommerce brands need an approach that captures every dollar flowing through the business.

01

Multi-channel chaos

Shopify, Amazon, Etsy, wholesale: each platform reports differently. Reconciling them by hand eats hours every week and introduces costly errors into your books.

02

Inventory tracking gaps

COGS, dead stock, reorder points. Most accountants do not understand inventory well enough to track it properly, and without accurate valuation your balance sheet and margins are unreliable.

03

Payment processor complexity

Stripe, PayPal, Shop Pay, Amazon Pay. Fees, refunds, chargebacks, and multi-currency transactions all need specialized handling, and each processor settles on a different timeline, so bank reconciliation is a moving target.

04

No real product profitability

You know your revenue, but do you know profit per SKU after shipping, fees, returns, and ad spend? Most brands do not, and without that you cannot decide which products to scale or sunset.

Questions

Ecommerce FAQs.

What multi-channel sellers ask us most.

Yes. We manage direct-to-consumer channels like Shopify and Amazon alongside wholesale and B2B. Each channel is tracked separately so you can see profitability across the whole business, from marketplace to retail to wholesale.
MATAX does not provide tax filing services. We do make sure your sales tax data is tracked and reconciled accurately across every channel, and we can recommend trusted partners who specialize in multi-state ecommerce sales tax compliance.
We set up automated rules inside your payment processor integrations, Stripe and PayPal among them, so chargebacks, fees, and returns are categorized and recorded as they happen. That stops revenue being artificially inflated and keeps your bank accounts reconciling cleanly at month-end.
We integrate your inventory management software directly into Xero for real-time COGS tracking. Every time a unit sells, the cost is recognized immediately, which gives you an accurate picture of gross margin and inventory asset value rather than a quarterly guess.
Yes. Many brands bring us in specifically to build the integrations and handle multi-channel reconciliation while keeping their existing tax CPA or strategic CFO in place. We are used to working as one part of a wider finance team.
