Invoices, credit notes, receipts, packing slips, quotes and returns forms for your Shopify orders.

• Issued automatically

  Each supported order gets its VAT invoice when it is paid, or at the moment you choose, in a gapless number series. Packing slips, receipts and returns forms keep their own series.

• Kept exactly as issued

  An issued invoice never changes. A refund becomes a linked credit note, and your design changes only when you switch, with at least 30 days' notice and 90 days to change back.

• Held, never guessed

  An order whose VAT treatment cannot be labelled waits in Needs you with the reason and the next step, and uses no invoice number.

Moving from another invoicing app? Summette continues your numbering from the next number. How switching from Sufio works

• The Shopify order page

  A Summette block on each order lists the order's documents and why each exists. Issue invoice now and Create packing slip are in the order's More actions.

• The Print menu

  Summette documents are in the Print menu of an order, and of the orders you select on the Orders list, printed together as one PDF.

• Issue invoices for selected orders

  Select orders on the Orders list and choose Issue invoices. Every order still passes every check.

• Shopify POS

  Staff print an order's invoice on a receipt printer or in A4, or email it, from the order or straight after a sale.

• Customer accounts and the thank-you page

  Buyers find their documents under each order in Shopify customer accounts and on the checkout thank-you page.

• Draft orders

  A Shopify draft order can become a pro forma invoice or a quote, each in its own number series and never a VAT invoice.

• Shopify Flow

  Your workflows can use five Summette triggers (Invoice issued, Credit note issued, Order held for review, Document emailed and Payment reminder sent) and three actions (Issue invoice for order, Send document and Create packing slip).

• Order fields other apps can read

  The invoice number, invoice status and paid date on each Shopify order, for Shopify Flow, order exports and other apps. Optional: off until you switch it on.

• The Shopify mobile app

  Summette is embedded in the Shopify admin, so it also opens in the Shopify mobile app.

• Every plan makes every document. The plans differ in how many invoices they include, a concierge setup call with our team on paid plans and up to ten storefronts sharing one allowance on Plus.
• Only issued invoices count. Credit notes, quotes, pro formas, packing slips and every other document never count, on any plan.
• Every paid plan includes a 30-day free trial.
• There are no usage charges. On a paid plan we keep issuing every invoice past the allowance, tell you, and suggest the plan that fits.
• On the Free plan, orders past the 25 included invoices in a month wait in Ready to issue, unnumbered, until your next month starts or you choose a paid plan. Nothing is lost.
• Join before 1 April 2027 and your price is locked for as long as you stay on that plan.
• All charges are billed by Shopify.
• Brands with up to ten storefronts can ask us for the private Plus plan: from $249 a month, 12,000 invoices a month.

What every plan includes beyond printing

• Originals that never change

  An issued invoice or credit note is stored exactly as issued and cannot be edited. A correction is a new document.

• Linked credit notes

  Refunds and cancellations become credit notes tied to the original invoice, and never credit more than was invoiced.

• VAT checks that hold rather than guess

  An order whose VAT treatment cannot be labelled waits in Needs you with the reason, and uses no invoice number.

• The accountant pack

  Period totals by rate, treatment and OSS destination, the original PDFs and CSV files, and a read-only link you can give your accountant.

• Structured e-invoice files

  XRechnung XML and ZUGFeRD PDFs for eligible German documents, and Factur-X PDFs for eligible French documents, ready to download.

• Missed orders found

  A monthly check that every Shopify order has an invoice or a reason, and a hold with the reason when an order your rules should have invoiced has none.

• A person to talk to

  Ask our team from the support centre in the app, on any plan, and a person replies. We aim to reply within one working day. A concierge setup call comes with every paid plan.

• For merchants established in Germany, France, Belgium, the Netherlands, Ireland, Austria, Luxembourg, the United Kingdom and Switzerland. Selling to every EU member state is covered, including consumer sales through OSS.
• Not available yet for merchants established in Italy, Spain or Portugal, because we do not connect to their national invoicing systems.
• Domestic business sales in Germany, France and Belgium wait for your review by default. In Germany you can switch on automatic ZUGFeRD invoices; in Belgium and France they wait while network delivery is unavailable.
• Network delivery over Peppol and through a French accredited platform is unavailable until a provider is active and a real delivery receipt has been verified. Summette creates the supported structured files for the merchant to download.
• Invoices and credit notes print in English, German, French and Dutch, the four reviewed languages, plus 24 draft packs you preview, check and switch on yourself. Packing slips, delivery notes, receipts, commercial invoices, gift receipts, returns forms, quotes, pro formas, payment reminders, customer emails, the order number and returns code on point-of-sale prints and the VAT-number check note on invoices use the four reviewed languages only: with a draft language chosen, they print in English. The Summette workspace, where you work, is in English. Setup, Home, Needs you, their help, the support centre and our emails to you are also in German and French, as draft translations; every other page is in English only.
• Summette is not accounting software and not tax advice. The VAT report is the arithmetic of the documents you issued, not a filed return.
