Hi there,

I'm looking for billing management software that can send emails sequentially to customers who purchase products with unique serial numbers. Ideally, the system would automatically send an email to the customer with the specific serial number they purchased. For example, if I have 10 serial numbers in stock, the first customer would receive an email with the first serial number and so on. I used to use WHMCS but I'm not sure if it has this capability. Do you have any suggestions or know of a software that can do this?

Thank you for your help!

WHMCS is widely considered as the most reliable choice for billing management software. Although there are other options available, WHMCS has become so ubiquitous that it's often recommended to stick with them as they are considered the gold standard.

My recommendation is to seek assistance from a professional to find typical solutions for these types of problems. However, the basic idea is to have a CRM system at the center of your strategy. Although Salesforce is widely used as a CRM system, it may be too costly for some. A free alternative is HubSpot, which could be a good starting point. For file storage, it's best to use a cloud drive such as Google Drive if your business is already on Google Suite or Office 365 otherwise. If you don't have a cloud solution yet, it's recommended to get one. In case you can't make it work, look into services like Dropbox for storing files in the cloud.

To complete the package, you'll require other SaaS solutions that can be easily integrated with your chosen CRM system. If they can't be integrated, they should be avoided. Consider using Mailchimp for email distribution and Typeform for forms, etc.
