E-COMMERCE & RETAIL

Bookkeeping for E-Commerce & Retail Sellers

Sales are up. Your payout is down. Where did the money go?

IF THIS IS YOU...

“Amazon/Shopify payouts never match my sales.”

...HERE'S WHAT CHANGES

Settlement reports reconciled with fees, refunds, and chargebacks recorded separately — so you see gross sales and the real cost of each channel.

IF THIS IS YOU...

“I don't know my margin by product or channel.”

...HERE'S WHAT CHANGES

Contribution reporting by channel and product category. That's where marketplace fee differences show their true cost.

IF THIS IS YOU...

“Inventory and COGS are a guess.”

...HERE'S WHAT CHANGES

Cost of goods and inventory movement tracked across channels, using counts and purchase records on an agreed cadence.

IF THIS IS YOU...

“I sell online AND in a store.”

Both reconciled and reported by channel — read separately or together.

Common Questions

Industry Accounting FAQ

Common questions on specialized accounting standards, revenue recognition, and CPA coordination.

How is deferred revenue handled for SaaS companies?

Contract revenue is tracked across the periods it covers, with deferred balances maintained and reconciled each month. Your CPA or auditor sets the recognition policy; NSI CAPITALS applies it consistently and ties schedules back to contracts.

Can you reconcile Amazon, Shopify, and other marketplace payouts?

Yes. We reconcile settlement statements from Amazon, Shopify Payments, Walmart, eBay, and Etsy against bank deposits, separating sales tax, shipping income, platform commissions, FBA fees, and return reserves.

Do you prepare Form 990 for non-profits?

We assemble the complete, reconciled financial package — including Statement of Functional Expenses, Statement of Activities, and grant schedules — required for your CPA or tax attorney to file Form 990.

How do you track restricted grant funds?

Using class and project tracking in QuickBooks or Xero, we isolate restricted donor funds, record qualifying expenditures against each grant, and generate budget vs. actual reports for grantor audits.

Who signs and files individual tax returns?

NSI CAPITALS prepares and organizes all schedules, reconciliations, and workpapers. Returns are reviewed, signed, and filed by your licensed CPA or EA (or we connect you with one of our licensed network partners).
