Accounting services for e-commerce sellers

Services Overview

Accounting built around how e-commerce actually works

Three services, each focused on a distinct layer of your financial picture — from daily transaction flow to quarterly fee audits and inventory valuation.

What We Offer

Focused accounting, not general practice

Brevmist works exclusively with e-commerce businesses. That focus shapes everything — the services we provide, the reporting formats we use, and the questions we know to ask. Sellers on Amazon, Shopify, Etsy, eBay, or any combination of platforms encounter financial complexity that general accountants rarely see on a regular basis.

Each of the three services below addresses a specific part of that complexity. You can engage one independently or combine them depending on where your accounting currently has gaps.

Service 01

E-Commerce Financial Management

Accounting services designed specifically for online retailers, whether you sell through one platform or several. The service covers revenue tracking across all your active marketplaces, payment processor reconciliation, inventory cost accounting, and management of multi-currency transactions.

Each month, your sales data is consolidated into a unified financial report — one clear picture regardless of how many selling channels you operate. Well-suited to sellers processing fifty or more transactions per month who want accurate, organized financials without dedicating internal time to piecing them together.

Service 02

Marketplace Fee Analysis

A structured breakdown of every fee category charged by the selling platforms you use. Referral fees, fulfillment charges, advertising costs, and subscription fees are mapped to revenue by channel — giving you a clear view of what each marketplace relationship actually costs.

The analysis is delivered as a quarterly report with trend comparisons across periods. Over time, it surfaces patterns that are easy to miss in raw payout statements and supports informed decisions about where to focus selling effort, how to price products, and whether a given platform remains worthwhile.

Service 03

Inventory Valuation & Costing

Calculation and documentation of inventory values using costing methods suited to your business structure. The service covers raw materials, work-in-progress, and finished goods, with appropriate overhead allocation applied consistently throughout.

Inventory records are maintained in a format that supports both financial reporting and tax preparation, reducing the lift at year-end and during audits. The service includes an annual physical inventory reconciliation support session to align physical counts with recorded values.

Combined Approach

Services that work well together

Each service stands on its own. Together, they cover the financial side of an e-commerce business from multiple angles — operational, analytical, and structural.

Month to month clarity

Financial Management keeps your books current and your reports ready, so you're never working from incomplete data when decisions need to be made.

Quarterly fee visibility

Fee Analysis layers on top of that operational base, translating raw payout data into a legible picture of what each platform is actually costing you.

Year-end readiness

Inventory Valuation ensures the product-holding side of the business is documented accurately, supporting clean financial statements and reducing tax-season complexity.
