We are updating the billing cycle for all Moss customers from Post Monthly to Pre Monthly billing. This article explains what this change means, why we are making it, what you can expect during the transition, and answers the most common questions.

Previously, your Moss subscription was billed on a Post Monthly basis — meaning you received an invoice on the first business day of each month for the services used in the previous month.

Going forward, your subscription will be billed on a Pre Monthly basis — meaning you will receive your invoice at the start of each billing cycle, for the upcoming period. Your billing date will be set to a fixed day of the month (your personal billing anchor date), and each invoice will cover a full month from that date forward.

This change is in line with our Terms & Conditions, which have always defined Pre Monthly as our standard billing model.

Pre Monthly billing is the industry standard for SaaS products and how the vast majority of subscription software is billed globally. This change allows us to:

When your billing is switched, you will receive two invoices in close succession. This is a one-time transition effect and will not happen again after the switch is complete.

You will receive a short partial invoice covering the days from the 1st of the current month up to the day before your new billing anchor date. This invoice is prorated, meaning you are only charged for the exact number of days in that period.

For example, if your new billing anchor date is the 17th, you will receive a partial invoice for the 1st to the 16th of the month.

From your billing anchor date onwards, you will receive a full Pre Monthly invoice covering one complete month. This will be your regular invoice going forward, issued on the same date each month.

Example: Anchor date is the 17th

No. Your pricing does not change. The only thing changing is the timing of when your invoice is issued and the period it covers. Your monthly rate stays exactly the same.

This is a one-time transition effect. Because you have already been billed for the beginning of the current month under Post Monthly billing, we need to issue a short bridging invoice to cover the remaining days until your new billing anchor date kicks in. After that, you will only ever receive one invoice per month.

The partial invoice is prorated based on the exact number of days in the bridging period, divided by 30 (our standard monthly billing period). Your full monthly rate is divided proportionally across those days.

Any discounts or add-ons on your account are applied in the same way — proportionally to the number of days in the period.

Yes. Pre Monthly billing is our standard model as defined in our Terms & Conditions. This change will be applied to all customers over time as part of a company-wide rollout. There is no opt-out.

If you are on a Pre Yearly (annual) contract, this change does not apply to you — your billing cycle is already set at the start of each annual period. This article applies to customers on a monthly billing cycle only.

No. You are only ever charged for the exact number of days of service. The partial invoice covers fewer days than a full month, so it will always be lower than your regular monthly invoice.

Your billing anchor date is set based on your contract renewal date. All future invoices will be issued on this fixed date each month.

No. The partial invoice only covers the days from the 1st up to your new billing anchor date. Your previous invoice covered the month before. There is no overlap.

All line items on your invoice — including add-ons such as ERP integration, accounting modules, and reimbursements — are prorated in the same way as your base subscription.
