How to Use METS?

Overview

METS stands for Meritto Engagement and Transactional System is Meritto’s centralized credit management system. It streamlines how institutes manage communication credits across Email, SMS, WhatsApp, Niaa, and Mio AI channels Mio AI Guide, Mio AI Voice, and Mio AI Coach.

METS now supports multi-currency configuration. The exchange rate is: 1 METS = 1 unit of whichever currency is configured for the institute. For example, if the institute's configured currency is INR, 1 METS = ₹1. if the configured currency is USD, 1 METS = $1.

Message consumption depends on the channel type. Email, SMS, and WhatsApp operate on CPM (Cost Per Message). Niaa, Mio AI Guide, and Mio AI Coach operate on CPS (Cost Per Session). Mio AI Voice operates on CPP (Cost Per Pulse). All rates are calculated in the institute's configured currency.

Key Benefits of METS

Why You Might See a Temporary Negative Balance in Ledger

  1. Sometimes Ledger shows a negative balance for a moment, in the middle of a transaction.
  2. This is not an error, and it does not mean the institute owes anything.
  3. It happens because a single bulk action — for example, a bulk send where some messages fail — is recorded in two separate steps: first the full cost is deducted, and shortly after, the portion that didn't go through is credited back.
  4. Between those two steps, the balance can briefly dip below zero.
  5. Once both steps are recorded, the closing balance is correct after clubbing both.
Example:
  1. An institute has 100 METs available.
  2. A bulk send of 150 messages is triggered, and the system deducts the full cost upfront — 150 METs — since that is the total cost of the batch. This takes the balance to -50 METs.
  3. Shortly after, 60 of those 150 messages fail to deliver, so the system credits back 60 METs for the ones that didn't go through.
  4. Once this reversal is applied, the balance becomes -50 + 60 = 10 METs — exactly right, since the institute is only charged for the 90 messages that were actually delivered (100 - 90 = 10).
  5. The dip to -50 METs in between was never a real shortfall; it was simply the deduction posting before its matching reversal.
  6. In short: if you see a negative number in METs ledger right after a bulk action, wait for the reversal entry — it typically posts within moments — and check the closing balance. It will reconcile.
How can my Existing Credits be migrated to METs?

All existing credit in systems will be migrated based on the defined automated calculation to METs:

  • Channel-specific credits, converted to METs using standard CPM/CPS.
  • Negative balances adjusted.
  • Unified system for better flexibility and visibility.
