Does Kintsugi calculate sales tax inside DualEntry?

DualEntry keeps calculating and recording tax exactly as it does today. Kintsugi's integration is read-only, so it never writes back to your invoices. Instead, Kintsugi uses your DualEntry invoice and customer data as the source of truth for monitoring your total tax exposure, and for preparing and filing the returns that follow.

Does Kintsugi sync sales orders and sales receipts from DualEntry?

No. Kintsugi's DualEntry integration pulls sales invoices and sales credit memos only, not sales orders or sales receipts.

What do I need to connect Kintsugi to DualEntry?

You'll need a DualEntry API key with Admin access. Create one from DualEntry under Settings > API Keys, then paste it into Kintsugi's Data Sources page to connect. Once you do, Kintsugi begins importing your customers, invoices, credit memos, and products automatically, and keeps pulling in new transactions from there.

I'm switching from Avalara. Can I use Kintsugi with my existing DualEntry setup?

Run Kintsugi alongside Avalara on your DualEntry-connected sales first. Nothing about your chart of accounts changes, so there's no upfront cutover. Once you've compared the two side by side, our team will help you complete the switch whenever you're ready.

What happens when I issue a credit memo in DualEntry?

Kintsugi picks up every sales credit memo from DualEntry and factors it into your tax liability at the transaction level, so a return reflects the adjusted amount you actually collected rather than the original invoice total.

Is my DualEntry data secure with Kintsugi?

Yes. Our read-only connection to DualEntry runs on least-privilege API access under Kintsugi's SOC 2 Type II certification, meaning we can see your data but never edit it. Data is encrypted at rest and in transit, and we'll provide security documentation for your finance and compliance team on request.

Kintsugi

DualEntry stays your system of record for customers, products, invoices, and credit memos. Kintsugi reads that same data to monitor where you owe sales tax, categorize your products correctly, and keep every return prepared and filed before it's due, all without asking your accounting team to touch a new system.

How it Works

Kintsugi connects to DualEntry as a read-only integration, so nothing changes about how your team invoices or manages your chart of accounts. Once connected, Kintsugi pulls in your customers, products, sales invoices, and sales credit memos to build a complete picture of your sales tax exposure across every state you sell into.

From there, Kintsugi's product categorization applies the right taxability rules to each item in your DualEntry catalog, so your exposure and liability numbers are built on accurate groundwork, not assumptions.

With DualEntry feeding Kintsugi as your indirect tax system of record, you're set up to automate registration, filing, and remittance in every jurisdiction where you owe, backed by the reporting your finance team needs to stay audit-ready.
