Go to sheets.google.com, create a new spreadsheet, and name it WAS Receipt System.
Click Extensions → Apps Script. Delete all existing code. Paste the contents of the WAS_AppsScript.js file you downloaded (delivered alongside this HTML file).
Click Deploy → New Deployment. Type: Web App. Execute as: Me. Who has access: Anyone. Click Deploy. Authorise when prompted.
The counter lives in your Google Sheet (the Counter tab). Every device reads from and writes to the same number, so Marie-Lynn and Chioma can never issue the same receipt number.
