Checking for additional charges before sending a multiparty private offer

The safest approach is to check both the private offer in Partner Center and the vendor's underlying pricing terms. A fixed upfront or installment payment schedule does not necessarily mean there are no additional recurring or usage-based charges.

Before sending the offer, check:

Pricing model: Fixed fee, monthly recurring fee, or consumption-based billing.

Metered charges: Usage limits, overages, and additional consumption rates.

Recurring fees: Support, maintenance, licences, or other monthly charges.

Payment terms: Confirm what the upfront or installment amount actually covers.

Vendor confirmation: Ask the ISV to confirm any charges outside the private offer.

Is it visible in Partner Center? Yes, partly. Microsoft documents that SaaS plans can combine recurring fees with metered usage charges, so the payment schedule alone isn't enough to establish the total cost.

My recommendation: make vendor confirmation mandatory before sending the offer.

Best practice: Get written confirmation of all recurring fees, metered charges, overages and third-party costs, and share these with the customer before acceptance.
