Ecommerce bookkeeping is not ordinary bank-feed categorization. Deposits arrive net of fees, refunds, reserves, chargebacks, gift cards, and taxes. Inventory moves across warehouses and channels. A sales platform can report revenue differently from the accounting system. If a firm does not understand those flows, the books may reconcile to the bank while the financial statements remain wrong.

The short answer

Ask an ecommerce bookkeeping firm exactly how it reconciles gross sales to net payouts, records inventory and cost of goods sold, handles returns and gift cards, monitors sales-tax liabilities, reports profitability by channel, and proves that the balance sheet is complete.

Platform and payout questions

1. Which ecommerce platforms, marketplaces, payment processors, and gateways do you support?
2. How do you reconcile gross sales, discounts, refunds, fees, reserves, chargebacks, and net deposits?
3. Do you use a connector such as A2X, Link My Books, or another tool, and who owns its setup and review?
4. How do you prevent duplicate revenue when sales data and bank feeds both enter the accounting file?
5. How do you handle timing differences between an order, shipment, payout, and bank deposit?

Inventory and COGS questions

1. How will inventory be valued, and which system is the source of truth?
2. How often are inventory and cost of goods sold recorded and reconciled?
3. Can you handle landed costs, freight, duties, bundles, assemblies, samples, shrinkage, and damaged goods?
4. How are returns and exchanges reflected in revenue, inventory, and COGS?
5. What happens when the inventory system, 3PL, marketplace, and general ledger disagree?

Tax and liability questions

1. How do you separate marketplace-collected tax from seller-collected tax?
2. Will you monitor sales-tax payable accounts even if another provider files the returns?
3. How do you coordinate with the income-tax CPA and sales-tax specialist?
4. How are gift cards, store credits, processor reserves, and customer deposits recorded?
5. What documentation will you provide for year-end tax and audit requests?

Reporting and advisory questions

1. Which monthly reports are included, and when will the books close?
2. Can reporting show gross margin and contribution margin by channel, product, or brand?
3. How will advertising, fulfillment, merchant fees, returns, and shipping affect profitability reporting?
4. Do you provide cash forecasts that include inventory purchases and payout timing?
5. Who explains the results and recommends actions?
6. What additional support is available for budgeting, pricing, inventory planning, financing, or an eventual sale?

How to evaluate the answers

Specific answers are more important than confident answers. A credible firm should describe the data source, reconciliation, review, deliverable, and exception process. “Our software handles it” is incomplete. Software can move data, but people still need to establish mapping, investigate differences, and decide how transactions belong in the financial statements.

Red flags

• Revenue will be recorded from bank deposits only.
• Inventory will be adjusted once a year with no monthly visibility.
• The firm cannot explain how refunds and fees reach the books.
• Sales-tax activity is ignored because a marketplace collects some tax.
• Every channel is combined even though you need channel economics.
• No one owns connector setup, reconciliation, or exception review.
• CFO support means only receiving a dashboard.

Match the firm to your stage

A low-volume seller with simple products may need accurate monthly bookkeeping and tax coordination. A multi-channel brand with inventory, 3PLs, financing, and rapid growth may need controller oversight, weekly cash planning, and SKU or channel analysis. Do not buy complexity you do not need, but do not force a complex operation into a basic package.
