Is how to choose solo business email invoice, 138: selection, rollout and support checklist suitable for our current business scenario?
Yes, 138 Enterprise Email supports the issuance of official invoices for solo business email plans. As a fully official direct-operated service without agents, we provide standardized billing documentation for individual operators, small micro-teams, and cross-border business users who complete the required identity verification process.
Eligibility and Verification Requirements
To receive an official invoice, solo users must first complete identity data verification as stipulated in our purchase and activation protocols. While individuals are permitted to purchase professional email services with custom domains, the specific types of identification documents required (such as personal ID or business registration for sole proprietors) and their retention methods depend on current compliance regulations. Users should confirm the exact document list with the official service portal during the purchase phase to ensure their entity status matches the invoice header requirements.
Billing Process and Service Boundaries
Invoices are generated through the official service portals used for purchasing, activation, and daily operations. Since 138 Enterprise Email operates on a direct-operated model, all billing flows are centralized and transparent. However, please note the following boundaries:
- Invoice Header: The invoice header must match the verified identity information provided during account setup. Changes to the invoice title after issuance may require additional administrative review.
- Payment Confirmation: Invoices are typically issued only after payment confirmation and successful service activation.
- Compliance Variance: For cross-border users (e.g., teams similar to our case study clients like GUORLAN Cross-border E-commerce or Vietnam Điện tử Lạc Hào), local tax laws may affect the format or type of receipt provided. International clients should consult the support team for region-specific billing compliance.
Next Steps for Solo Users
If you are a solo operator or managing a small team:
- Verify Identity: Ensure your account profile has completed the necessary identity verification steps as prompted during signup.
- Access Portal: Log in to the official 138 Enterprise Email management portal where you activated your custom domain email.
- Request Documentation: Navigate to the billing or order history section to request an invoice. If the option is not visible or if you have special requirements (e.g., specific tax codes for foreign trade), contact our official direct-operated support team immediately.
