A long-established invoicing app, on the App Store since 2013, built around tax-correct documents: separate credit notes for refunds, VAT number validation and e-invoicing. Every plan caps how many invoices you can create a month.
The short version
Sufio is the stronger choice if tax compliance is the job: EU B2B, e-invoicing, VAT validation and translated documents are what it is built for, and we would rather say so. If you want invoices delivered on rules, into Slack or Drive, without a monthly invoice cap, Pro does that for $19 where Sufio’s unlimited plan is $129.
Overview
What each one does
Both apps turn Shopify orders into PDF documents. They part company on what happens next.
Send Invoice Pro
Documents that deliver themselves
Reads every order, builds a branded PDF, and sends it on a rule you set once - by email, into
a Slack channel, or filed to your own Google Drive.
Nine document types, from invoices to return forms
Hourly to monthly schedules, or on order placed, fulfilled or paid
Conditions, quiet hours and per-schedule timezones
Flat monthly pricing, never per document
From $0 · $9 · $19 · $39 per month

Where each one is stronger
We have listed their advantages at the same length as ours. If one of theirs matters more to
your store, use them - you will find that out faster from us than from a trial.
Send Invoice Pro
What we do better
Unlimited invoices at $19. Sufio’s $19 Growth plan stops at 50 invoices a month; unlimited is its $129 Premium plan. Pro is $19 with no cap.
A free plan. 70 invoices a month at no cost. Sufio starts at $7 for 15, after a 14-day trial.
Slack and Google Drive delivery. Their listing shows neither.
Rules without a $129 plan. Conditions, quiet hours and per-schedule timezones are part of our scheduling, and our top plan is $39. Sufio lists its automation workflows on Premium at $129.
Vendor commissions and payouts on Pro, which their listing does not mention.
Sufio
What they do better
Peppol, ZUGFeRD and Factur-X. Three e-invoicing standards we do not support.
Tax depth. VAT number validation, EU B2B tax exemptions, HS codes, commercial invoices, and tax support listed for the EU, India, Canada and the US.
Documents in more languages, translated by local accountants.
Customer self-service. Customers download invoices in your store, and it lists Shopify POS, Klaviyo, Recharge and Stripe among its integrations.

Decide
Which one to choose
The useful question is not which app is better, it is which job you are trying to finish.
Choose Sufio if
You sell B2B in the EU, need e-invoicing or VAT validation, or need documents in several languages.
Choose Send Invoice Pro if
You send a lot of invoices and want no monthly cap, Slack or Drive delivery, or scheduling rules without a $129 plan.
Install free, send your first invoice in minutes, and pay only when you outgrow it. Orders are
encrypted and handled to Shopify’s Protected Customer Data standard.
