How the invoicing works at Sid.

Updated today

Invoicing Schedule

Invoices are typically issued on the 5th of each month and must be paid within 25 days from the invoice date.Payments are primarily made in advance, with a one-time transition period at the start of the collaboration.

First Invoicing Cycle (Start of Collaboration)

When a collaboration starts mid-month, the first invoicing cycle will include multiple invoice periods to align billing with our standard monthly invoicing schedule.

Example:
If the collaboration starts on April 17, the first invoice will be sent on May 5 and will include the following periods:

  • April 17–30 (partial past month)

  • May 1–31 (current month)

  • June 1–30 (upcoming month)

This means the first invoice may cover past, current, and upcoming periods to ensure the invoicing schedule is aligned going forward.

Ongoing Monthly Invoicing

After the initial invoicing cycle, billing is simplified and follows a single-invoice, advance-payment model.

Example:
On June 5, an invoice is issued covering the period July 1–31. The invoice must be paid no later than June 30. From this point onward, each invoice will:

  • Be issued on the 5th of the month

  • Cover one upcoming month

  • Be paid in advance

Summary

  • Invoices are sent on the 5th of each month

  • Payment terms are 25 days

  • The first invoice may include multiple billing periods to align with the monthly cycle

  • All subsequent invoices cover one upcoming month and are paid in advance
