Rillet is a modern AI-native ERP and accounting platform built for software companies.

​
Prerequisites

You need to have a valid Rillet account, an API key issued from Rillet, and admin rights on Hyperline.

​
Setup

1

In Hyperline, navigate to the Settings > Integrations page

2

Click Connect on the Rillet card

3

Paste your Rillet API key

Hyperline uses the API key to authenticate every call to your Rillet account. The key can be revoked from Rillet at any time.
4

Map your invoicing entities to Rillet subsidiaries

On the Settings > Integrations > Rillet page, link each Hyperline invoicing entity to a Rillet subsidiary. The subsidiary drives the currency, accounts and tax codes available in the rest of the configuration.
5

Choose a revenue recognition mode and configure mappings

Pick Revenue recognition only or Full accounting sync, configure your products and (optionally) enable subscription contract sync. See Settings and Mapping below.
6

That's it!

Your Hyperline account is ready to send invoices, credit notes, payments and contracts to Rillet.

​
Settings

You can configure the following options on the Settings > Integrations > Rillet page:
  • Subsidiary: Rillet subsidiary used to push invoices and contracts for the selected invoicing entity.
  • Revenue recognition mode: see Revenue recognition mode below.
  • Bank account: cash account used to post payments in Rillet. Required when Full accounting sync is selected. The list is pulled from your Rillet chart of accounts.
  • Sync subscriptions as contracts: when enabled, Hyperline pushes each subscription to Rillet as a contract so Rillet can schedule revenue automatically. See Contract sync.

​
Revenue recognition mode

Hyperline can push invoices to Rillet in two different ways:
  • Revenue recognition only (default): Hyperline sends invoices so Rillet can recognise revenue. Rillet automatically settles payments on its side, so payments are not pushed from Hyperline.
  • Full accounting sync: Hyperline sends invoices and the matching payments to Rillet, including accounts receivable tracking. Requires a bank account to be configured.
The mode applies to both invoices and credit notes.

​
Mapping

​
Customers

To link an existing Rillet customer to a Hyperline customer, open the Hyperline customer page, click Edit in the Integrations section, and paste the Rillet customer ID. For bulk linking during initial onboarding, contact our support team or use this API endpoint. If a Hyperline customer is not linked to any Rillet customer, the behavior depends on the Customer sync mode configured in Settings:
  • no synchronization — the customer must be linked manually before any invoice can be pushed; otherwise the invoice push fails.
  • from Hyperline to Rillet — the customer is automatically created in Rillet the first time it is needed (typically on the first invoice push).

​
Products

Every invoice line item must be mapped to a Rillet product. For each product in Hyperline, go to the Accounting section of the product page and enter the corresponding Rillet product identifier in the Product code field. If a line item is missing a product mapping, the invoice push fails with a clear error listing the affected products so you can fix the mapping and retry.

​
Tax codes

Tax codes are configured at the invoicing entity level — set up tax codes with automatic computation in the tax settings of the relevant invoicing entity. Tax codes are then resolved according to what is configured in Hyperline and pushed to Rillet on each invoice line.

​
Synchronization

When you connect your Rillet account, Hyperline automatically sends invoices, credit notes, customers, payments and (optionally) contracts with their complete details.
By default, only data created after the connection date is synced. To push older data, please contact our support team.
Synchronization is one-way: Hyperline → Rillet. Rillet is queried read-only to fetch metadata (subsidiaries and chart of accounts).

​
Customer synchronization

Hyperline supports 2 modes of synchronization for customers:
  • no synchronization: customers are not automatically created — they must be linked manually before any invoice can be pushed.
  • from Hyperline to Rillet: customers created in Hyperline are automatically created in Rillet with their details.

​
Invoice and credit note synchronization

Invoices and credit notes are pushed as native Rillet invoices and credit memos. Updates made to an invoice in Hyperline are propagated to the matching Rillet record automatically.

​
Payment synchronization

In Revenue recognition only mode, payments are not pushed to Rillet — Rillet automatically marks invoices as settled on its side once they are recognised. In Full accounting sync mode, Hyperline supports a per-payment-method sync setting (card, SEPA / ACH / BACS direct debit, bank transfer, Apple Pay, Google Pay, Stripe Link, external, other). Each can be set independently to:
  • no synchronization: payments are not synchronized.
  • from Hyperline to Rillet: payments settled in Hyperline are pushed to Rillet against the corresponding invoice using the configured bank account.
The synchronization delay is 5 minutes maximum.

​
Contract sync

When Sync subscriptions as contracts is enabled, Hyperline pushes each Hyperline subscription to Rillet as a contract. Rillet uses the contract to schedule revenue recognition automatically over the subscription term. Contracts are kept in sync as the subscription evolves: changes are pushed as updates, and when a subscription is cancelled the matching Rillet contract is ended on the cancellation date.
