## Content

**Intro:** Choosing between WhatsApp, SMS, email and chat for ERP notifications is mostly a cost per delivered message question. This worksheet puts each channel in a row so you can see spend, delivered volume and the real price of a message that actually arrives.

**Sections:**

#### How to use the worksheet

**Body:** Add one row per channel and use case, for example order updates versus one time passcodes, because rates differ by message type and country. Enter monthly volume, the rate from your provider invoice, and the delivery rate from your delivery receipts. The sheet calculates monthly spend, delivered messages and the cost per delivered message, then totals and blends across rows. Export to Excel to share with procurement.

**Bullets:**

- One row per category and country
- Use invoiced rates, not list prices
- Add platform and number rental fees as extra rows

#### The calculation

**Body:** Monthly spend is volume times rate. Delivered is volume times delivery rate. Cost per delivered message is the rate divided by the delivery rate, so a 0.045 SMS with 90 percent delivery really costs 0.05 per arrival. Blended cost is total spend divided by total delivered. Some channels bill on sent messages and some on delivered, so check the contract, because that changes whether delivery rate matters for spend.

#### Common mistakes

**Body:** Comparing price alone ignores whether the recipient can use the channel. A cheap email that nobody reads is not cheap. Also do not forget fallback logic: if you retry a failed WhatsApp message over SMS, count both attempts. Finally, free internal channels such as Teams still cost integration and maintenance time, which belongs in your business case even if the message rate is zero.

**Bullets:**

- Include fallback sends as separate rows
- Check whether billing is on sent or delivered
- Add integration run costs for internal channels

**Cta:** If you want a single notification layer that picks the right channel from ERP events and logs delivery back to the record, Netray can design it with you.

**Faq:**

#### Why does delivery rate change cost?

**Answer:** If you pay per sent message, every failed delivery is wasted money, so the effective price per arrival is the rate divided by the delivery rate. If billing is on delivered messages, enter 100 for billing purposes.

#### Where do I get delivery rates?

**Answer:** From delivery receipts or status webhooks of each provider over a representative month. Do not use marketing figures.

#### Does it handle multiple currencies?

**Answer:** Work in one currency and convert provider rates first. For several countries, keep one row per country with its converted rate.

#### Can I add columns?

**Answer:** Export to Excel and extend it there, for example with tax or volume discount tiers.
