What Is Synder?

Running an online store is thrilling until the books hit your desk. Every payout from Shopify, Amazon, Stripe, and PayPal lands with different fees, currencies, and tax rules. Synder steps in as an automation layer that pipes that clutter straight into QuickBooks Online, Xero, NetSuite, or Sage Intacct while keeping everything tidy for reconciliation. You connect your sales channels once, choose how much detail you want, and Synder quietly syncs sales, refunds, fees, and even inventory data in the background.

Key Features

Seamless Integrations

With connections to over 30 platforms—including Shopify, Amazon, eBay, Etsy, Stripe, PayPal, Square, and more—Synder lets multichannel sellers keep one source of truth. Two integration “slots” come with the Basic plan, and you can add more as you scale. The connectors map products, customers, and payment specifics so you do not have to juggle CSV files ever again.

Dual Sync Modes

Not every accountant wants thousands of tiny records. Synder offers Per Transaction Sync for line-level detail and Summary Sync for a single daily journal entry or payout-based entry. You pick the mode per organization, and swaps are as easy as spinning up a new org when your needs change. Hourly or fully-fetched schedules keep your ledgers updated without manual clicks.

Smart Rules Automation

Smart Rules are Synder’s “if-this-then-that” engine. You can auto-tag Amazon fees to an Expense account, assign California sales the proper tax code, or trigger thank-you emails after a Stripe payment. Rules update transactions almost instantly after sync, eliminating late-night manual edits and giving your workflow a boost. 

AI Dashboards

Launched in May 2025, AI Dashboards let you ask plain-English questions like “Show me total sales by channel last quarter” and get charts or numbers on the spot. The natural-language layer sits on Synder’s register, so data never leaves your account. It is currently in open beta for all Summary Sync users at no extra cost. 

Payout & Reconciliation Engine

Synder’s Payout feature posts deposits and processor fees to the correct clearing and bank accounts so the Banking tab in QuickBooks lights up with instant matches. One click later, the month is reconciled. That same feed can track COGS and inventory counts so your margins stay accurate as stock moves.

Pricing: Plans That Grow With Volume

Synder keeps it simple with a 15-day free trial on every plan. After that:

Basic: $65 per month (or $624 per year) for up to 500 transactions, two integrations, hourly sync, multicurrency, and one extra user. 

Essential: starts around $115 per month and scales to 3,000 transactions. Good for brands that just outgrew spreadsheets. 

Pro: begins near $275 per month and supports tens of thousands of monthly orders plus advanced features like consolidated reporting.

Premium: custom quote for high-volume or enterprise setups needing dedicated support and custom API work.

Annual billing knocks roughly 20 percent off the sticker price. Volume overages simply prompt you to bump up instead of shutting off syncs, so books keep flowing.

FAQ

Which accounting platforms does Synder work with?

Synder connects to QuickBooks Online and Desktop, Xero, NetSuite, and Sage Intacct right out of the box.

How long does set-up take?

Most ecommerce stores get connected in under 15 minutes. You choose your sync mode during onboarding and can import years of historical data in one batch.

Can I switch plans as my volume grows?

Yes. Upgrades are prorated, and your data stays intact. Downgrades happen at the next billing cycle once your monthly transaction volume is below the new limit.

Does Synder support multiple currencies?

Absolutely. Synder pulls the gateway’s exchange rate and records the home-currency value automatically, keeping foreign sales compliant.

Is there a free trial?

Every new account gets a 15-day free trial with full functionality to test integrations and Smart Rules before committing.

Final Thoughts

If you spend more time exporting transactions than growing your shop, Synder is a lifesaver. The combo of deep integration, zero-touch reconciliation, and now AI-powered dashboards makes it feel like you just hired a back-office robot that never sleeps. For solo founders the Basic plan already beats hiring a bookkeeper for routine imports. For agencies and accountants, multi-org management and Smart Rules free you to advise instead of data-clean. Try the trial, flip on Daily Summary Sync, and see if your bookkeeping to-do list does not shrink by tomorrow.
