💰New Field: estimated_monthly_income in /profile

• Starting on March 23, 2026, the GET /profile/{identifier} endpoint will return a new field: estimated_monthly_income.
• This field represents the sum of all invoice amounts for the identifier in the last 30 days, expressed in MXN.
• When no invoices exist in that period, the field returns null.

⚠️ What Changes

• New field added — estimated_monthly_income will appear in all /profile responses. It is a BigDecimal value serialized as a string (e.g. "11139.00"), or null.
• No breaking changes — this is an additive change. Existing fields (personal_info, address, employment_status) remain unchanged.

💡 What This Means for You

• One simple income output — instead of interpreting multiple invoice records from /invoices, you now get a single estimated monthly income directly in /profile.
• Calculated from invoices only — this value is derived exclusively from invoice data. It does not use IMSS, ISSSTE, or /employments data.
• 30-day rolling window — the calculation sums all invoice amounts from the last 30 days. At least 1 invoice must exist in that period; otherwise the value is null.
• Nullable — if the identifier has no invoices in the last 30 days, expect null. Make sure your integration handles this case.

🧾 Example

If an individual has the following invoices in the last 30 days:
