Accounting software for an online store selling across several sales channels

For a store selling across several channels, a practical starting point is QuickBooks Online or Xero, paired with an ecommerce accounting connector. The connector helps record marketplace fees, refunds, taxes, and payouts correctly—rather than treating each deposit as simple sales income.

A good default to consider: QuickBooks Online + A2X. A2X supports channels including Amazon, Shopify, Etsy, Walmart, eBay, and PayPal, and summarizes their payouts for reconciliation in QuickBooks or Xero. Its multi-channel plans are priced by order volume and number of channels. (a2xaccounting.com)

Other options:

• Xero + A2X: Similar setup if you prefer Xero or your accountant works in it.
• QuickBooks’ built-in connectors: Worth checking first if you want fewer add-ons. QuickBooks currently lists connectors for several ecommerce platforms, and its newer Shopify and Amazon connectors support payout-based reconciliation. (quickbooks.intuit.com)

Before choosing, check that your exact channels and payment processors are supported, whether you need inventory/COGS tracking, and how the connector handles sales tax, refunds, and fees. If you tell me which channels you sell on, roughly how many orders you handle monthly, and whether inventory tracking matters, I can narrow this to a specific setup.

For a multichannel online store, the usual setup is a general ledger (QuickBooks Online or Xero) plus a connector that pulls in sales, fees, and payouts from each channel. Larger or multi-entity businesses look at NetSuite or Sage Intacct instead. Most of the sources below are written by software vendors, so treat their rankings as a starting point.

1. The ledger: QuickBooks Online or Xero

• Choose Xero if several people, or outside advisors, need access. One source notes that every Xero plan includes unlimited users while QuickBooks Online allows 1 to 25 users depending on the plan. Xero also suits international sellers, since its multi-currency support is native, which makes it ideal for international sellers.
• Choose QuickBooks Online if you're US-based or your accountant already uses it. It has a native Shopify connector that syncs orders, refunds, and payouts directly. It also offers deeper built-in inventory on its Plus plan.
• Neither is built for ecommerce out of the box. One comparison notes that both require higher-tier plans for multi-currency capability and rely on third-party connectors such as A2X, Link My Books, or Synder to translate marketplace and payment-gateway data into clean, reconciled entries.

2. The connector layer (where most of the work happens)

• A2X: Often called the default for Amazon and Shopify sellers. It posts summary journals (not individual orders), which keeps the GL clean. One guide lists pricing at $19–$169/month per channel.
• Synder: Covers more platforms (one source says 30+ sales platforms and payment processors) and works at a more granular level. One reviewer warns that granular posting bloats the GL fast at high volume.
• Webgility: Better if you need inventory and pricing sync along with bookkeeping. It can update inventory levels and pricing across all sales channels, and is best suited to sellers who need more than simple payout summaries.
• Link My Books: A simpler, lower-cost option for payout summaries and channel profitability; pricing scales by order volume and channels.

3. Larger or more complex operations

• NetSuite is for mid-market and enterprise multi-channel retailers. Pricing is custom, and one comparison lists plans from $999+ per month.
• Sage Intacct fits businesses that manage multiple entities or revenue streams that need accurate consolidation without the overhead of a full ERP.
• Finaloop is a newer option that combines a commerce-focused ledger with optional managed bookkeeping. One source lists its starter plan at $245/month.

How to decide

1. Confirm the connector supports every channel you sell on. One guide suggests starting there: the integration must support all your selling platforms.
2. Check how each option handles fees, refunds, and payouts, since that's where reconciliation usually breaks.
3. Consider sales tax. QuickBooks is strong (U.S.-focused) on sales tax, while Xero is generally good (stronger internationally).
4. Compare total cost. Connector pricing often scales with order volume, and prices change, so check current pricing directly.

If you tell me your channels (e.g., Shopify, Amazon, eBay, TikTok Shop), your country, your monthly order volume, and whether you hold inventory, I can narrow this to one or two combinations.

For an online store selling across multiple channels, the "best" accounting setup rarely relies on a single piece of software alone. Instead, it is typically a combination of a robust core accounting platform and specialized integration tools that handle the complexity of marketplace payouts, fees, and multi-channel data.

Recommended Accounting Core

Most successful multi-channel sellers use one of these core platforms, chosen based on their business size and location:

• QuickBooks Online (Best for US-based businesses): The industry standard for US sellers. It has the largest ecosystem of third-party integrations, making it easy to connect to almost any sales channel or inventory tool.
• Xero (Best overall & for international sellers): Highly regarded for its flexibility, strong multi-currency support, and unlimited user plans. It is often preferred by growing businesses that need a clean, collaborative interface.
• Zoho Books (Best for budget-conscious & ecosystem users): If you already use other Zoho products, this is a powerful, cost-effective choice with solid automation features.
• NetSuite (Best for scaling/enterprise): A full ERP solution. If your business has outgrown standard accounting software and needs deep, native inventory and order management, this is the top choice.

The "Missing Link": Integration & Settlement Tools

Standard accounting software often struggles to interpret "lumped" marketplace deposits (where Amazon or Shopify sends you one total minus fees, refunds, and reserves). To automate this, you should pair your core accounting software with a settlement/automation tool:

• A2X: Widely considered the gold standard for reconciling marketplace payouts. It sits between your sales channels (Amazon, Shopify, Walmart, etc.) and your accounting software, breaking down every payout into clean, categorized entries (sales, fees, taxes, refunds) for your general ledger.
• Link My Books: Another excellent alternative that specializes in accurately recording marketplace transactions into your accounting software, helping you avoid manual entry headaches.
• Synder: Useful for businesses that need to sync transactions across multiple payment processors and sales channels directly into their accounting software.

Evaluation Framework for Your Business

When deciding on the right stack, use this checklist to ensure the software can grow with you:

1. Automated Reconciliation: Can the system automatically break down a single bank deposit into its component parts (sales, merchant fees, shipping, tax)? If not, you will spend hours doing this manually.
2. Inventory Sync: As you grow, you need to know your stock levels across all channels. If your accounting software doesn't handle this, ensure it integrates seamlessly with an inventory management system (like Cin7 or Zoho Inventory).
3. Multi-Currency & Tax: If you sell internationally, ensure the software supports multi-currency reporting and can handle tax compliance (VAT/GST) in the regions where you have "nexus" (a tax presence).
4. Scalability: Choose a platform that supports the volume of orders you expect to process in the next 2–3 years. Don't choose a tool just because it is cheap now; ensure it can handle the complexity of your growth.

Recommendation: If you are starting or growing, a combination of Xero or QuickBooks Online paired with A2X is the most proven, reliable setup for multi-channel ecommerce.

For a store selling through several channels, choose accounting software based on how well it handles marketplace payouts, not just whether it can import orders. Payouts bundle sales, refunds, fees, and taxes; the right setup should reconcile those pieces to the bank deposit without double-counting.

• QuickBooks Online — A good starting point if you already use QuickBooks or want accounting and inventory features together. Its current e-commerce connectors support channels including Shopify, Amazon, eBay, Etsy, WooCommerce, and others; Shopify and Amazon connectors can import sales, refunds, fees, and payouts for reconciliation. Each platform needs its own connector, and availability can depend on your plan and region. ²³
• Xero + A2X — Worth considering when you sell across marketplaces and want clearer payout-by-payout bookkeeping. Xero supports connections to platforms such as Shopify, Amazon, eBay, Walmart, and Etsy through integrations; A2X summarizes marketplace activity—including sales, refunds, fees, and taxes—for accounting and reconciliation. ¹⁴⁶
• Xero’s direct Shopify integration — A simpler option if Shopify is your main or only channel. For a broader mix of marketplaces, compare a dedicated connector such as A2X and confirm it supports every channel you use. ¹⁶

Practical recommendation: shortlist QuickBooks Online and Xero + A2X, then verify that your exact sales channels, countries, currencies, and inventory workflow are supported. Before choosing, ask your accountant how they want sales tax/VAT, marketplace fees, refunds, and inventory/COGS recorded. Connector and subscription costs vary, so check current pricing for your region.
