HYBRID PLANS

Combine seats and usage in one plan

Bill a recurring subscription or seat charge alongside metered AI usage. Add eligible prepaid credits and customer-specific rates as your pricing evolves.

Trusted by the most innovative companies

Bill seats and AI usage together

For example, 20 seats at $30 and 1,000 document analyses at $0.10 produce $600 in seat charges and $100 in usage, before credits and tax. One Lago plan can price both charges.

Apply credits to the intended charges

A wallet restricted to the analysis metric can apply $50 of eligible credits to the $100 usage charge while leaving the $600 seat charge intact. Lago Premium can set customer-specific subscription fees and usage rates.

Create custom metrics

Create complex usage metrics with custom SQL and use advanced aggregation to ensure accurate charges.

Change prices without losing billing history

When a customer upgrades, keep the same subscription ID. Lago bills earlier usage at the old rate and later usage at the new rate. A downgrade can start at the next renewal. On Premium, preview the proposed plan change and its estimated invoice before applying it.

Hybrid billing FAQ

What is a hybrid billing plan?

A hybrid plan puts a fixed subscription or seat charge and metered usage on the same customer agreement. For example, you can charge for seats and the document pages those users analyze.

Can credits cover usage without covering seats?

Yes. Configure a Lago wallet to cover usage charges. In an illustrative invoice, three seats at $10 and seven analyzed pages at $1 make $37 in charges. A $5 usage credit leaves $32 due before tax; the $30 seat charge stays intact.

What happens when a customer changes plans?

Assign the new plan using the existing subscription ID. An upgrade can take effect immediately: earlier usage keeps its original rate, while later usage takes the new rate. A downgrade is scheduled for the next billing period.

Can I preview an upgrade or downgrade invoice?

Yes, with Lago Premium. Send the active subscription and proposed plan code to the invoice preview endpoint. It estimates the fees, eligible discounts, taxes, and total without issuing an invoice. This previews one plan change; test a wider pricing migration separately. See invoice previews →
