How to Choose Ecommerce Accounting Software: A Buyer's Checklist

Colleen Quattlebaum

June 1, 2026

Most ecommerce sellers choose accounting software the wrong way. They start with price, or with whichever tool their accountant already knows. The better approach is to start with the seven things the software actually has to do, then see which tools clear the bar.

An ecommerce business has accounting requirements a generic small-business tool was never built for. Marketplace settlements arrive as net deposits with a dozen fee types buried inside. Inventory costs shift with every lot and every tariff. The same product has different margins on different channels. A tool that handles a service business or a brick-and-mortar shop will not handle this cleanly.

Here are the seven criteria that separate software that fits an ecommerce operation from software that creates a second job. Score each tool you evaluate against all seven before you look at the price.

1. Settlement reconciliation, is it automatic?

Every marketplace deposits a net amount after fees. The software has to take that deposit, break it into sales, refunds, referral fees, fulfillment fees, advertising, taxes, and reserves, and post each piece to the correct account in your accounting platform without you touching a spreadsheet.

The question to ask on a demo: "Show me a real Amazon settlement reconciling end to end." If the answer involves exporting a CSV and mapping columns by hand, the tool is not automating the work. It is relocating it.

2. COGS, is it calculated per unit, automatically?

Revenue without matching cost of goods sold produces books that look more profitable than the business is. The software should maintain a live inventory ledger, apply a costing method (FIFO or weighted average) automatically, and post COGS for each period based on units actually shipped.

The question to ask: "When I receive a new lot of inventory at a different landed cost, what do I have to do?" The right answer is "enter the lot once." The wrong answer is "update a cost field on every SKU manually each month."

3. Multi-marketplace, one tool or one per channel?

If you sell on three or more marketplaces, running a different reconciliation process per channel is how errors and missed close deadlines happen. The software should handle every channel you sell on in one workflow, and the pricing model should not punish you for adding channels.

The question to ask: "What does the monthly cost look like at four marketplaces and 2,000 orders a month?" Per-channel pricing models can quietly triple between the demo and the real invoice.

4. SKU-level reporting, can you see profit by product?

Knowing the company is profitable is not the same as knowing which products make the money. Software that only produces a clean company-level profit and loss statement leaves you guessing at the SKU level, which is where pricing, inventory, and advertising decisions actually get made.

The question to ask: "Can I see contribution margin for one SKU, on one channel, trending over the last six months, without exporting anything?"

5. Accounting platform fit

The software should integrate cleanly with the accounting platform you use or intend to use. QuickBooks Online, QuickBooks Desktop, or Xero are the common ones for ecommerce. If you are on QuickBooks Desktop specifically, confirm support directly; many newer tools are QuickBooks Online only.

6. Returns, reimbursements, and the messy edge cases

The difference between adequate and excellent ecommerce accounting software shows up in the edge cases: unsellable returns that have to be written down separately from customer refunds, FBA reimbursements for lost inventory, multi-currency settlements on international marketplaces, and marketplace-facilitator sales tax.

7. Where it is going, the AI layer

Accounting software is moving from "clean books" to "clean books plus answers." The forward-looking question is whether the tool can answer business questions from your data. Which SKUs lost money last month, what your margin trend looks like by channel, all without you building a report. This is the AI CFO layer, and it is becoming a real differentiator rather than a gimmick.

A simple scoring method

Score each tool 0-2 on each of the seven criteria: 0 if it does not do it, 1 if it does it with manual effort, 2 if it does it automatically. A tool scoring 11 or below will create work. A tool scoring 12-14 is doing the job. Only after you have the scores should you bring price into the decision.

FAQ

Do I need ecommerce-specific accounting software, or will QuickBooks alone work?

QuickBooks (or Xero) is your accounting platform, the general ledger. Ecommerce-specific software sits on top of it, turning marketplace settlements into accurate entries.

How much should ecommerce accounting software cost?

Ecommerce-specialized tools start around $149/month for entry tiers and scale to $300+/month based on marketplace count, order volume, and feature depth.

When should I switch accounting software?

When your current process can't keep the books closed within ten days of month-end, when you can't see profit by SKU, or when adding a marketplace means adding manual work. Any one of those is the signal.

What's the most overlooked criterion?

COGS automation. Many tools reconcile revenue and fees well but leave cost-of-goods as a manual monthly task. That gap is where margin errors hide until year-end.
