Partnership
Billecta is one of Sweden's leading invoicing platforms. Millentic is the AI-native workspace for financial operations. Together, we solve one of the most persistent problems in B2B finance: the gap between where billing data lives and where invoices need to go.
The problem most companies don't talk about
Billecta's invoicing engine is powerful. But using it fully requires connecting your operational systems to its API, and that's where many businesses get stuck. A broadband provider with thousands of subscribers, a property manager billing hundreds of tenants, a utility running complex tiered tariffs: these companies have the customer data, the billing logic, and the invoicing volume. What they lack is the technical capacity to wire it all together without a lengthy, expensive IT project.
The result is that invoicing stays manual, error-prone, or delayed. Finance teams export spreadsheets, re-enter data by hand, and spend days each month on work that should take minutes.
What the partnership makes possible
Billecta now offers Millentic as a whitelabel data layer, embedded directly into the Billecta product experience. The flow works like this:
- A Billecta customer uploads unstructured billing data, a spreadsheet from their CRM, an export from their provisioning system, a file from their ERP, in whatever format they already use.
- Millentic handles the data transformation: cleaning, normalising, mapping customer records, applying billing logic, and structuring the output as valid invoice instructions.
- Those instructions are passed directly to Billecta's invoicing engine, which handles the rest: delivery, payment collection, reconciliation, and bookkeeping.
No custom API work required. No IT project. No data consultant. The entire flow is configured and owned by the finance or operations team.
“Through our integration with Millentic, we're making it even easier for our customers to invoice smarter. By combining Billecta's invoicing engine with Millentic's platform, we're creating a complete solution for tomorrow's finance departments.”
A real example: broadband and infrastructure providers
Broadband providers, energy resellers, and infrastructure companies share a common challenge: they manage large subscriber bases with recurring billing needs, but their operational systems were never designed to talk to an invoicing platform. Building a direct API integration to Billecta is technically possible, but it requires developer time, ongoing maintenance, and a level of IT capacity most of these organisations simply don't have.
With the Millentic layer in place, these companies can:
- Import subscriber data and service details in any format, including unstructured files and spreadsheet exports.
- Run automated transformation jobs that apply billing rules, handle exceptions, and generate clean invoice instructions for thousands of customers at once.
- Send those instructions to Billecta automatically, on a schedule, without touching a single spreadsheet or filing a single IT ticket.
What used to take days of manual preparation now runs in the background. Finance teams get the accuracy and speed of a full API integration without the cost or complexity of building one.
Who this is built for
This partnership is designed for Billecta customers who need to send high volumes of invoices but whose systems aren't ready for a direct API integration. In practice, that covers a wide range of industries:
- Utilities and infrastructure: broadband providers, energy resellers, water companies billing on meter data and tiered tariffs.
- Property and real estate: landlords, property managers, and housing associations handling recurring rent, service charges, and utility billing for large portfolios.
- Platforms and marketplaces: businesses invoicing on behalf of third parties where data comes from multiple upstream sources in inconsistent formats.
- Any organisation managing subscription or usage-based billing at scale without the developer capacity to build and maintain custom integrations.
“Billecta and Millentic are creating new possibilities for financial administration that previously couldn't be achieved without large, time-consuming, and expensive integration projects. This partnership is already generating significant efficiency gains for our customers.”
