Best Accounting Software for Ecommerce (2026): QuickBooks, Xero, A2X and Synder

A2X does one job: it reads each payout or settlement from your sales channel and posts a summary of it to your ledger, so the entry lines up with the deposit in your bank. Reconciliation becomes matching one entry to one deposit, instead of hunting through hundreds of orders, and the fees, refunds and sales tax inside each payout land in their own accounts rather than being netted into sales.

From the Basic plan, A2X’s COGS feature calculates cost of goods sold per SKU per payout and posts an entry that moves that cost from your inventory asset account to your COGS expense account. That gives you real gross margin without a full inventory system. A2X can also pull past periods from Shopify to help you clean up old books.

Which plan to pick: Shopify Mini at $29 a month if you have under 200 orders a month and do not need COGS. Basic at $45 for up to 500 orders, or if you want COGS. If you sell on more than one channel, compare A2X’s Multi-channel plans, which combine 2 to 10 channels in one subscription.

Watch out for: order counts. Plans are sized by monthly orders per channel, so check your volume across your busiest months, not an average. Prices here are from A2X’s Shopify pricing page, which we read through a search of A2X’s site because its pricing calculator did not load for us.

Xero is a strong ledger for an online store paired with a connector. Every plan includes bank reconciliation, sales tax, W-9 and 1099 management and real-time reports, and Xero does not charge per user, which matters when an owner, a part-time bookkeeper and an outside accountant all need access.

For product businesses, Xero’s Inventory Plus add-on is available on Growing and Established; Xero lists it as optional rather than giving a price on the plan page, so check the cost before you rely on it. Many stores instead let A2X or Synder post COGS to Xero and keep detailed stock counts in their store platform or an inventory app.

Which plan to pick: Growing at $59 a month for most stores, since it removes the Early plan’s invoice and bill caps and includes auto-reconcile. Established at $97 if you buy from overseas suppliers or sell in several currencies.

Watch out for: the Early plan’s limits. Twenty invoices and five bills a month is enough for a store that bills nothing directly, but wholesale orders or many supplier bills will push you to Growing. Xero raised US prices on October 1, 2026; the prices here are the new ones.

QuickBooks Online is the safe ledger choice for a US store, mainly because of the people around it. Most US bookkeepers and accountants know it, so it is easy to find help, and every plan includes free accountant access. Both connectors in this guide post to QuickBooks Online, and Synder’s entry plan supports it alongside Xero.

For product businesses, the key plan is Plus, which adds inventory tracking along with classes and locations, so you can split results by sales channel or warehouse. If you rely on a connector for COGS, Simple Start or Essentials may be enough.

Which plan to pick: Essentials if a connector handles COGS and you need up to 3 users. Plus if you want QuickBooks to track inventory quantities and value, or report by class or location.

Watch out for: price. The prices above are Intuit’s retail list prices, re-checked on October 12, 2026. On an earlier check, Intuit’s accountant pricing page showed higher list prices for Essentials, Plus and Advanced ($85, $140 and $340). Confirm the price at checkout.

Synder covers more payment channels than A2X, which makes it a good fit for stores that sell through a website, a marketplace and in person, or that bill subscriptions through Stripe. It syncs sales from 30+ platforms into QuickBooks Online, Xero or Puzzle on the entry plan, with NetSuite, Intuit Enterprise Suite and Sage Intacct on higher plans, and checks balances in Synder before posting so the books match each platform.

Synder can sync product names, costs and quantities to your books for COGS, and it also lists transaction reconciliation that flags missing or mismatched entries; check which plan includes it. The pricing page also lists per-plan differences in how customers are recorded, from a single generic customer to individual customer names, so check which plan matches the detail your accountant wants.

Which plan to pick: Basic at $52 a month billed yearly if you have up to 500 sales transactions a month. Essential, from $103 a month billed yearly, if you need more volume, live chat or a faster support lane; Synder says the final price depends on your monthly transaction needs.

Watch out for: transaction counts. Synder counts every synced transaction except processing fees against your plan, so a store with many small orders can outgrow Basic quickly. Use the 15-day free trial to measure your real volume, because purchases are non-refundable.
