Choosing an SMS platform and finding connectivity suppliers are important decisions. They do not settle every question involved in running the business.
You still need to decide who your customers will be, what traffic you intend to handle, how you will charge for it, and who owns each part of the operation. Those decisions give your platform provider and suppliers something concrete to configure and test.
This checklist is for founders, commercial leads and technical teams preparing a wholesale SMS operation. Use it before the first interconnection discussion, then keep it open through testing and handover. An unanswered question is a planning item, not something to hide to make the launch date look better.
1. Describe the operation you are building
Start with a short operating brief rather than a list of software features.
Write down:
- The customers you intend to serve and the traffic you plan to accept.
- The countries or destinations you want to cover first.
- How customers will submit messages to your operation.
- Your initial volume assumptions, including peaks and uncertainty.
- Who owns customer onboarding, supplier relationships and day-to-day operations.
You do not need a perfect forecast. A clearly labeled estimate is more useful than an unexplained number.
Be specific about what you are not launching yet. A narrower first scope gives the people doing the setup a clearer set of requirements. You can assess additional markets, integrations and traffic types separately instead of treating them as already covered.
Also identify the questions that need advice for your markets, including permitted traffic, sender requirements, privacy and contractual responsibilities. A platform selection does not establish that every planned use is permitted.
2. Separate the platform from connectivity
Give each responsibility an owner before discussing the interconnection details.
Your operating business needs to establish what it sells, which customers it accepts, and which suppliers it contracts with. The platform and its agreed configuration support that operation. Connectivity suppliers have their own offers, onboarding requirements and commercial terms.
For each supplier, ask:
- Which traffic, destinations and use cases are covered by the proposed arrangement?
- What onboarding, payment or credit conditions apply?
- What connection details, limits and security requirements must be agreed?
- Who is the technical contact, and how are issues escalated?
- Which tests are authorized, and what will count as an acceptable result?
Do not treat an initial commercial conversation as a completed supplier agreement. Equally, do not assume your platform quote includes traffic, supplier approval or daily management of your business unless those services are explicitly agreed.
Keep access credentials and account details in an appropriate secure system. A shared planning sheet can record who holds them and whether access has been verified without exposing the secrets themselves.
3. Agree the commercial and configuration rules
Before asking someone to configure accounts, routes and rates, make the intended rules explicit.
Accounts and responsibilities
Agree how customer and supplier accounts will be identified, who can change them, and who approves commercial changes. Make sure the commercial and technical teams use the same references when discussing a connection or a rate profile.
Rates and currencies
Record the applicable rate source, currency, effective date and change process. Specify who checks that the intended rates are the ones being used. Avoid relying on an old spreadsheet attachment without identifying which version applies.
Balances, credit and limits
Decide which balance, credit or operating-limit rules you need and what should happen when a relevant limit is reached. Then confirm how the chosen platform and supplier arrangements support those rules. Do not assume the desired behavior is already configured.
Routing and failure handling
Document the intended routing choices and any fallback behavior you require. Ask what happens when a route is unavailable or a submission fails, and who decides whether a retry is appropriate. Test the agreed behavior rather than relying on the label of a feature.
Counting and charging
Ask each provider to define the event being counted and the event being charged. Keep submission, acceptance and delivery-status questions distinct.
For Crossbow SMS, the platform's commercial structure includes setup, fixed service and usage charges based on submitted messages. The applicable rates, included services and billing terms are set out in the quote. That does not define another supplier's charging rules, or answer every question about rejected submissions, retries and multipart messages.
Write those questions down and resolve them with the relevant provider. A sample reconciliation is easier to assess when the counting rules are explicit.
4. Test the agreed scope
Prepare the test plan with the relevant parties before generating traffic. Use authorized destinations and agreed test conditions; do not use real customer traffic as an improvised test environment.
For each test, record the intended result, the actual result, the relevant identifiers and who reviewed it. Include the questions you need to answer about:
- The agreed message path through the operation.
- Available submission responses, logs and delivery-status information.
- How the same test is identified across the systems involved.
- Authorized failure, limit and retry scenarios.
- The counters and charges expected under the agreed commercial rules.
An unexplained difference should remain an open issue. Do not turn a test into a pass simply because one part of the flow worked.
You also need a handover decision: who can authorize launch, which unresolved items are acceptable, and which ones block it? Record the reasoning rather than leaving it in a private chat.
5. Make the handover operational
A handover should identify the people and procedures needed after setup.
Confirm who monitors the agreed service indicators, who investigates customer enquiries, who can change rates or routes, and how a supplier or platform issue is escalated. Agree access, security, backup and recovery responsibilities within the service scope rather than assuming another party owns them.
Keep a short list of open decisions with an owner and a next action. That is more useful than a completed checklist whose tick marks nobody can explain.
A simple readiness review
Before moving ahead, ask each responsible person to identify:
- What has been agreed and where it is recorded.
- What has actually been configured or tested.
- What remains unknown or outside the launch scope.
- What they need from someone else before proceeding.
The accompanying readiness worksheet is designed for this discussion. Tick an item only when the answer and responsible owner are clear. Leave unresolved items open.
Discuss your planned SMS operation
Crossbow SMS provides a cloud platform for routing, customer management and billing. DataTechLabs handles the agreed initial configuration, helps establish supplier interconnections and provides operational advice as you get started.
You normally bring your own suppliers and routes. If you are still planning your operation, the useful starting point is your intended customers, initial scope and the decisions you need help resolving.
