Nexus as usage grows

How Orb connects to Kintsugi
Orb builds invoices as usage accrues, which makes manual sales tax tracking hard to keep accurate. Kintsugi reads each invoice as it syncs and keeps your liability, nexus, and filings current.

Connect & sync
Connect Orb with your Kintsugi API key. Customers, invoices, credit notes, and products sync as your usage-based billing generates them, giving you a live, itemised view of exposure.
Calculate what you owe
Kintsugi classifies each Orb line item as usage and product mix shift, and calculates what you owe in every US state, plus VAT and GST in 100+ countries.
Register, file, and remit
Kintsugi registers you where you owe, files every return, and remits on schedule as metered revenue grows, with audit-ready reporting behind every return.
What Kintsugi syncs from Orb
| Synced | What Kintsugi does with it |
|---|---|
| Customers | Matched to the location each invoice is taxed in. |
| Invoices | Read as they're generated, so usage-based revenue counts toward nexus and liability right away. |

| Products | Classified for taxability by jurisdiction, even as your product mix changes. |
Who uses Kintsugi with Orb
Usage-based and metered pricing
Invoices that change every cycle get the same accuracy as flat subscriptions, line item by line item.
Crossing thresholds faster than planned
A usage spike can create nexus mid-quarter. Kintsugi flags it as the invoices sync, not at quarter end.
Switching from Avalara or TaxJar
Run Kintsugi in parallel on your Orb billing and compare results, with no cutover on day one.
How Orb sales tax works
What Orb does
Orb doesn't calculate tax itself. It sends invoice data to a third-party tax provider you connect, applies the result to the invoice, and reports the finalised transaction back to that provider.
Where it stops
In Orb's words, it doesn't decide how much tax you owe, and filing and reporting sit with the provider rather than with Orb.
What Kintsugi adds
Kintsugi reads your Orb invoices, credit notes, and products as they sync to calculate what you owe on usage-based revenue, monitor nexus, and register, file, and remit for you.
