What Am I Buying? 5 Compliance Apps Built for Real Stores
You shouldn't need a law degree to sell online. Here is exactly what each Domillio app does, the expensive problem it eliminates, and how it protects your Shopify business.
Tax Exemption Desk
Wholesale buyers get charged sales tax at checkout, get upset, and force manual refunds while emailing PDFs. In a state audit, missing certificates result in thousands in back-taxes.
Adds a buyer portal (/apps/tax-exempt) to your store. Buyers upload resale permits. You verify with 1 click, Shopify exempts them on future checkouts, and you export audit CSVs anytime.
CPC Safety Desk
US Federal law requires an official Children's Product Certificate (CPC) for every toy, baby item, or kid's apparel SKU. Without it, retail partners and US Customs will seize goods.
Stores all your test lab reports centrally, generates compliant, print-ready CPC certificates with tamper-proof QR codes verifiable by customs officers.
GPSR Compliance Desk
Under EU GPSR 2023/988, non-EU stores shipping consumer products to European shoppers must list an authorized EU contact and safety labels. Without them, customs will hold parcels.
Automatically displays verified EU Responsible Person information and required safety disclosures on product pages and packing slips so parcels pass customs without delay.
EPR Packaging Desk
If you ship boxes, mailers, or bubble wrap to Germany (LUCID) or France (ADEME), you are legally required to register and pay recycling fees or face severe marketplace bans.
Tracks packaging material weights (cardboard, paper, plastic, glass) based on actual orders shipped. Generates exact totals for your annual recycling reports in 1 click.
Prop 65 Defense Desk
In California, bounty lawyers target Shopify stores for products containing trace chemicals without mandatory pre-purchase warnings, demanding $50k+ settlements.
Dynamically attaches statutory warning triangles and legally compliant text to matching product detail pages and order confirmations for safe-harbor legal protection.
How It Works in 3 Simple Steps
No complex enterprise setup or endless configuration. You can be fully compliant and approving wholesale certificates in under 5 minutes.
Install in 1 Click
Add Domillio from the Shopify App Store. It instantly integrates with your store without altering your Liquid theme code or slowing down page speed.
Buyers Self-Serve
Wholesale customers visit your store's /apps/tax-exempt portal, enter their business details, and upload their resale permit directly from their phone or computer.
1-Click Approval & Tax-Free Orders
Review the state tax ID in your Shopify Admin and click Approve. Shopify automatically updates their customer account to tax-exempt so their future checkout orders are 100% tax-free.
Why Domillio Beats Legacy Compliance Software
Traditional enterprise compliance platforms charge hidden per-transaction cuts and trap your customer data in proprietary silos. Domillio gives power back to the merchant.

Frequently Asked Questions
Common questions regarding suite deployment, domain routing, and specific desk capabilities.
What is the Domillio Compliance Suite?
Domillio is an integrated software suite of specialized regulatory compliance applications for Shopify merchants. We provide sovereign, audit-ready solutions across wholesale sales tax exemptions, children's toy safety (CPC/CPSIA), European cross-border regulations (GPSR 2023/988), European packaging recycling (EPR/VerpackG), and California Proposition 65 clear warning defense.
Can I run Domillio apps on my own server or preferred cloud host?
Yes. All Domillio apps support a Sovereign Self-Hosting model using Docker, PostgreSQL, and Cloudflare Zero Trust Tunnels. You can run the entire suite on your own Linux server, private bare-metal, VPS (Hetzner, DigitalOcean, Linode), or container platforms (AWS ECS, Google Cloud Run, Railway, Render) while retaining 100% ownership and physical custody of your compliance records.
Do the apps require modifying my Shopify theme code?
No. Domillio apps use standard Shopify App Proxy routes (such as /apps/tax-exempt and /apps/gpsr-compliance) to render secure, responsive, theme-native interfaces without modifying your liquid template files or causing theme update regressions.
How do custom domain routing and subdomains work across the suite?
Domillio.org acts as the central hub, knowledge wiki, and global FAQ center. Individual applications operate on their own dedicated subdomains (tax.domillio.org, cpc.domillio.org, gpsr.domillio.org, epr.domillio.org, prop65.domillio.org) with isolated database tenancy, independent OAuth scopes, and dedicated SSL certificates.
Compatible Cloud Hosting Platforms & Self-Hosted Servers
Deploy Domillio on your own terms. Run on your private on-premises Linux hardware, dedicated bare-metal, or any leading cloud container platform with complete data sovereignty and zero vendor lock-in.
