Automated Tax Compliance With Avalara, Built Into Checkout
Calculate the right sales tax, VAT, and GST in real time at checkout, manage exemptions, and file returns without spreadsheets or guesswork.
Tax is a moving target you can't manage by hand
Tax rules change constantly and differ by every jurisdiction you sell into. In the USA, thousands of state, county, and city rates combine with economic nexus thresholds that can create a filing obligation in a state you've never set foot in. In Europe, VAT rates and rules vary by country, and cross-border sales pull in registration, invoicing, and reporting duties. Newer regimes in Qatar and the wider Gulf add fresh VAT obligations, and rates and terminology shift by market, from MWST in Germany and Switzerland to moms in Sweden. Managing all of this with static rate tables and spreadsheets leads to under-collection, audit exposure, missed filing deadlines, and checkout errors that cost you sales and trust.
Avalara AvaTax, wired directly into your commerce engine
Hepek integrates Avalara AvaTax into your storefront and back office so tax is calculated in real time at the point of checkout, invoicing, or order processing, using jurisdiction-aware logic that reflects current rates and boundaries. AvaTax handles multiple tax types from one platform, including US sales and use tax, EU and Gulf VAT, and GST, and keeps rates and rules current without manual updates. We connect economic nexus tracking, exemption certificate management, cross-border duty and import tax calculation, and automated returns preparation, so the whole compliance lifecycle runs from a single source of truth with a complete audit trail on every transaction.
So funktioniert es
- 1
Compliance discovery & nexus review
We map where you sell, ship from, and hold inventory, then review your US economic nexus exposure and your VAT and GST registration obligations across Europe, the Gulf, and other markets. This defines exactly which jurisdictions AvaTax needs to calculate and file for.
- 2
AvaTax integration into checkout
We connect AvaTax to your storefront, cart, and ERP so tax is calculated in real time at checkout and on every invoice or order. Address validation and product tax codes ensure the right rate is applied down to the correct city, county, state, or country.
- 3
Exemption certificate management
We wire in exemption certificate handling so B2B and reseller customers can submit certificates that are validated against jurisdictional rules. Expired, invalid, or missing certificates are flagged, and exempt transactions are taxed correctly instead of guessed.
- 4
Cross-border duties & customs
For international orders we configure cross-border calculation so customs duties, import taxes, and VAT or GST are estimated at checkout, with HS code classification to keep customs and trade documentation accurate and landed costs transparent to buyers.
- 5
Automated returns & filing
We set up automated returns so tax collected is reconciled and filings are prepared, filed, and remitted on schedule for US sales and use tax and for VAT. This offloads deadline tracking and paperwork while keeping a defensible audit trail.
- 6
Monitoring, alerts & hardening
We enable nexus threshold alerts and monitor calculations, exemptions, and filings after launch. As you enter new states or countries, we extend the configuration so compliance keeps pace with your growth instead of trailing behind it.

Vorteile
Accurate tax at every checkout
Buyers see the correct sales tax, VAT, or GST in real time based on their exact location, so you collect the right amount up front and avoid the under-collection that turns into liabilities later.
Nexus surprises eliminated
Automated economic nexus tracking warns you before you cross a US state threshold, so you never discover an unregistered filing obligation during an audit or a costly catch-up filing.
Multi-region VAT and GST handled
One integration covers US sales tax, EU VAT, Gulf VAT, and GST, including regional variants like German and Swiss MWST and Swedish moms, so selling into new markets doesn't mean rebuilding your tax logic.
Exemptions managed, not guessed
Validated exemption certificates keep B2B and reseller orders tax-correct and audit-ready, removing manual certificate chasing and the risk of taxing exempt customers or exempting the wrong ones.
Filing off your plate
Automated returns preparation and filing reduce the manual effort behind every deadline, cutting the risk of late or inaccurate filings and the penalties that follow them.
Cross-border clarity
Estimated duties and import taxes at checkout give international buyers transparent landed costs and reduce surprise fees, abandoned orders, and rejected shipments at the border.
Häufig gestellte Fragen
How does Avalara calculate sales tax at checkout?
Avalara AvaTax calculates tax in real time at the moment of checkout using the customer's validated address and the product's tax code. It applies current rates and rules for the exact jurisdiction, combining state, county, and city sales tax in the USA or the correct VAT or GST rate internationally. Hepek integrates it directly into your cart and invoicing so every order is taxed accurately without manual rate tables.
What is economic nexus and does Avalara track it?
Economic nexus is a US rule where selling above a certain revenue or transaction threshold into a state creates a sales tax obligation there, even without a physical presence. Avalara tracks your sales against each state's thresholds and alerts you as you approach or cross one, so you can register and begin collecting on time. Hepek configures this monitoring so nexus obligations never catch you by surprise.
Does Avalara handle VAT for Europe and the Gulf?
Yes. Avalara supports VAT and GST alongside US sales tax from one platform, covering EU countries, Gulf markets like Qatar, and regional variants including German and Swiss MWST and Swedish moms. It applies the correct rate per jurisdiction at checkout and can automate VAT returns preparation and filing. Hepek scopes your registration obligations before integrating so the setup matches where you actually sell.
How are exemption certificates managed?
Exemption and resale certificates are collected from B2B and reseller customers, validated against each jurisdiction's rules, and stored centrally. The system flags certificates that are expired, invalid, or missing so those sales are taxed correctly and stay audit-ready. Hepek wires this into your checkout and customer records so exempt orders are handled automatically rather than by manual review.
Can Avalara calculate cross-border duties and customs?
Yes. For international orders, Avalara can estimate customs duties, import taxes, and VAT or GST at checkout, and automate HS code classification to keep customs and trade documentation accurate. This gives buyers transparent landed costs and reduces surprise fees and border delays. Hepek configures cross-border calculation as part of your tax integration when you ship internationally.
Does Hepek support tax compliance outside the USA?
Yes. Hepek implements Avalara tax automation for merchants across the USA, Europe, and Qatar and the wider Gulf, with engineering rooted in Bosnia and Herzegovina and clients in markets including Germany, Switzerland, and Sweden. We handle multi-region VAT, GST, and sales tax as part of the build. Reach us at info@amygdal.com to discuss your jurisdictions.
