Daily summary entries that balance · $14.99 a month

Shopify into QuickBooks Online as clean daily summary entries — that provably balance.

Your Shopify sales as clean QuickBooks Online entries: one summary entry per day of sales, one per day of refunds and one per payout, through a Shopify clearing account. Every entry must balance to the cent before export. Every payout is reconciled against its charges, refunds, fees and adjustments; one that does not add up is held with the difference named. Gift cards sold are a liability, and discounts, shipping and sales tax each go to their own account. Download the import file.

Questions

The ones merchants actually ask

Which Shopify plans does it work on?

Works on every Shopify plan. Where a part needs Shopify Plus, the app says so on the screen rather than hiding it.

How am I billed?

$14.99/month through Shopify's own app billing, on your normal Shopify bill. No card is taken here and there is no share of your sales.

What happens to my data if I uninstall?

Shopify tells the app the moment you uninstall, and the app erases what it kept for your store. Customer data requests from Shopify are answered the same way. The full detail is on the app's own privacy page.

Is it on the Shopify App Store?
