Stop filing taxes on guesswork. Get Avalara working across every sales channel.
You sell in multiple states. Your ERP, ecommerce store, and marketplaces each handle tax differently. We connect them all to Avalara so every checkout, invoice, and return calculates the right tax, files on time, and passes an audit. Proposal in 3 days. Go live in as few as 14.
Manual tax compliance fails the moment you cross a second state line
"We had nexus in 9 states and handled tax manually in our ERP. The audit found we undercollected $200K in two years. Avalara paid for itself in month one."
Every day without Avalara is a day of hidden liability
Drag the sliders to your numbers. See what manual tax compliance actually costs your business each year in audit risk, penalties, and wasted labor.
What your Avalara integration actually handles
A real Avalara integration does more than route tax calls. It manages exemptions, syncs history, handles refunds, and keeps returns data current across every platform.
Tax calculated correctly at every transaction
Every checkout, invoice, credit memo, and return triggers an AvaTax API call. Rates match the exact ship-to address, product taxability, and buyer exemption status. No manual lookup. No guesswork.
Exemption certificates managed automatically
B2B buyers need zero-tax transactions. We connect CertCapture to your checkout and ERP so certificates are collected, validated, and applied at the line-item level. No spreadsheets. No chasing PDFs.
Returns filed on time, every state, no manual entry
Transaction data flows into Avalara Returns automatically. Filings go out on schedule across all nexus states. Your finance team stops spending hours on data entry.
ERP and ecommerce data synced to Avalara in real time
Orders, invoices, credit memos, and refunds write back to Avalara as they happen. Works with NetSuite, SAP, Dynamics, BigCommerce, Shopify, Magento, and custom APIs.
Built on Avalara's native APIs, not a third-party wrapper
Generic connectors wrap Avalara's API behind middleware. That middleware breaks on version updates. It cannot handle partial refunds, bundled products, or marketplace facilitator rules. We build directly against AvaTax, CertCapture, and Returns endpoints. Your tax data stays accurate and current.

Three things that separate a tax integration from a tax incident
Tax-domain knowledge, not just API access
Most integration teams treat Avalara as a REST endpoint. They POST transactions and call it done. We understand the tax content engine, nexus logic, and product taxability rules. That knowledge prevents the silent errors other teams miss.
Edge-case handling built in from day one
Partial refunds. Bundled products. International VAT. Digital goods. Subscription billing. Marketplace facilitator laws. Each one breaks basic integrations. We map and handle all of them during scoping, before code is written.
Scoped proposal before you commit anything
Submit your system map. We send a line-by-line proposal in 3 business days. It covers the build, data mapping, testing plan, and maintenance terms. You see the full scope before spending a dollar.
Questions before you start your Avalara integration
No. We build against Avalara's REST API directly. Your system only needs to provide order data. If it has an API, we can route transactions to Avalara. No native connector required.
Single-platform integrations go live in 14 to 21 days after sign-off. Multi-platform builds covering ERP, ecommerce, and marketplaces take 28 to 42 days. Add 7 to 10 days if you need exemption certificate management.
Yes. Avalara's API accepts historical transaction imports. We handle data cleaning, format conversion, and batch upload as a separate phase. Historical data matters for accurate returns filing from day one.
Every integration includes fallback logic. If Avalara is unreachable, orders keep processing with your fallback rate. The system retries and commits queued transactions when the connection restores. You get an alert the moment fallback mode activates.
Yes. Avalara's Global Tax Compliance module handles VAT, GST, and indirect taxes across 190 countries. We scope international requirements separately because thresholds, invoice formats, and filing schedules differ from US sales tax. Flag your international volume in the brief and we include it.
