Slack delivery
Post a document straight into a channel with preview and download links. None of the four list Slack delivery.
Where we stand
Send Invoice Pro launched in August 2026, so we have no review history and the apps below have thousands between them. What we have instead is a different job: they print and generate, we deliver on rules. Each page below lists what the other app does better, at the same length as what we do better.

Send Invoice Pro vs Shopify Order PrinterThe one you already have
All comparisons checked 28 August 2026 against the live Shopify App Store listings, each linked from its page.
In short
What actually makes us different
Three things none of the apps above offer, and one thing they mostly do better than us.
Rules, not just automation
Conditions on order value, tags, channel, country or segment, plus quiet hours, per-schedule timezones and a holiday freeze.
Flat pricing
Priced by feature, not by order volume. Your bill does not climb because you had a good month.
And the honest gap: we do not support e-invoicing, Peppol, ZUGFeRD or Factur-X. If you sell B2B into the EU, Order Printer Pro and Vify both do and we do not - that is worth knowing before you install anything.
