Kintsugi calculates tax on Hyperline invoices and credit notes while they are still editable, and writes the rate to each taxable line.
Kintsugi reads your Hyperline customers, products, and invoices to track your exposure in the US and 100+ countries, and sends nexus alerts.
Kintsugi registers you, files your returns, and remits on schedule. Filing starts at $75.
Hyperline runs your billing. Kintsugi connects to your Hyperline account and adds the tax to your invoices, so you keep the billing setup you already have.
In Kintsugi, open Data Sources and choose Hyperline. Sign in to Hyperline as an admin, approve Kintsugi, and pick the invoicing entity to connect. There is no API key to create or copy.
Kintsugi pulls in your customers, products, invoices, and credit notes. Set an import start date if you want to limit how far back it goes.
In Hyperline, set the tax engine for that invoicing entity to Manual and turn off automated tax collection and Anrok. Turn on Generate draft invoices for your subscriptions, and set a grace period if you bill for usage.
Click Enable Tax Collection on the connection and finish the checklist. Kintsugi registers the webhook it needs in Hyperline, so there is nothing to install.
| Synced | What Kintsugi does with it |
|---|---|
| Invoices | Your invoices, with line items. Kintsugi adds tax to drafts and to usage invoices in their grace period, and counts final invoices toward nexus and your returns. |
| Credit notes | Linked to the original invoice, so refunds net out correctly. Editable credit notes get tax too. |
| Customers | Name, email, billing address, and tax ID where present, plus whether the customer is exempt |
| Products | Your product catalog, which Kintsugi categorizes for tax |
| Tax rate (returned to Hyperline) | Written onto each taxable line of editable invoices and credit notes. Hyperline shows one combined rate per line, and Kintsugi keeps the full breakdown. |
Kintsugi reads invoice status to tell whether a sale counts, so it does not import payments as a separate record.
Kintsugi signs in through Hyperline's own approval screen and reads invoices, credit notes, customers, and products to track nexus, build reports, and file your returns. It doesn't change anything in Hyperline. You can deactivate the connection at any time, and the data already synced stays in Kintsugi.
Turn on Tax Collection and Kintsugi calculates tax on editable invoices and credit notes and writes the rate back to Hyperline, so the tax your customer sees matches the tax Kintsugi files.
Flat-fee, per-seat, and usage-based invoices all land as invoices, so they sit in one place.
Kintsugi keeps one connection per entity, so you connect each one on its own and keep each legal entity's liability separate.
Credit notes link to the original invoice, and product and address issues surface in one list.
Hyperline runs your products, customers, subscriptions, and invoices. It applies tax rates you set yourself, or connects to an outside tax provider.
Hyperline doesn't tell you where you have nexus, register you, or file your returns.
Kintsugi calculates tax on your Hyperline invoices and credit notes, tracks your nexus, registers you where you owe, and files and remits on schedule.
