Kintsugi integration

Calculate sales tax and VAT on Bunny quotes and invoices through Kintsugi, with tax treatment driven by the tax code on each price list charge.

What the integration does

Tax at quote and invoice

Kintsugi is called when a quote is priced and when an invoice is raised, so the signed amount and the billed amount agree.

Driven by tax codes

The tax_code field on each price list charge determines treatment, so different product types are handled correctly in every jurisdiction.

Nexus monitoring

Kintsugi tracks where your sales create filing obligations — useful for a SaaS business acquiring nexus faster than it notices.

Simple credentials

An API key and an organization ID is the whole connection. Debug logging is available while you validate the setup.

If you sell SaaS in the United States, nexus is the trap. You do not have to open an office in a state to acquire a filing obligation there — enough revenue or enough transactions will do it, and the thresholds differ state by state.

Kintsugi is built around that problem, and the Bunny integration wires it into the two moments where the answer is needed: pricing a quote and raising an invoice. The tax treatment of each line comes from the tax code on the price list charge, so the same configuration that drives Avalara drives Kintsugi.

Switching vendors later

Because tax treatment lives on your price list charges rather than inside the tax plugin, moving between supported tax engines is a configuration change rather than a re-modelling exercise.

FAQ

Frequently asked questions

How does Kintsugi compare to Avalara in Bunny?
Both plug into the same points in Bunny and are driven by the same tax_code field on price list charges. The choice is about which tax vendor you prefer commercially, not about what Bunny can do with them.
What do I need to connect it?
A Kintsugi API key and your organization ID. Debug logging can be enabled while you validate the configuration.
Does it handle VAT?
Yes, alongside US sales tax.

Keep the stack you have

Bunny sits between your CRM, your tax engine, your payment processor and your ledger — so quoting, subscriptions, usage and invoicing share one system of record without anyone migrating off the tools they already use.
