The problem

Free Order Printer isn’t UK VAT-ready

Shopify’s free Order Printer helps with documents, but many UK sellers still struggle to get sequential numbers, reverse-charge wording, zero-rated lines and a buyer VAT number onto a proper invoice without fighting Liquid templates.

Full-suite apps often cost $10–40/mo

Established invoice apps are excellent when you need everything. For small UK stores that mainly need VAT-correct invoices and packing slips, that price band can feel heavy.

Built for UK Ltds first

VatSlip is an early-access project aimed at UK Shopify merchants (with EU wording where useful). We will not claim HMRC approval or that any invoice “guarantees compliance” — templates and settings are tools; your accountant remains the authority. Operated by Witkowski Holdings Limited.
