Customer Self-Service App for Machine Shops

A typical job starts as an email with a drawing attached, passes to an estimator who checks the material and cycle time, and then becomes a job traveler on the floor. Each handoff copies details by hand. A revised drawing may arrive after the setup is already running on a Haas or a Mazak, and nobody is certain which revision the operator is working from.

The breakdown points are easy to spot. A purchase order is entered with the wrong quantity, a first article report sits in a folder waiting for a signature, and a customer asks for a cert that the quality team filed under the wrong heat lot. A self-service app will not fix a bad estimate, but it removes the constant chasing that eats the shop's office hours.

• Drawings arrive by email and are saved under inconsistent file names
• Revision changes reach the floor late or not at all
• Customers ask for status on jobs that the shop has already shipped
• Material certs are searched for by hand in the quality folder

Not every machine shop handles restricted work, so the rules that matter depend on the customers. Shops making parts for defense programs may need to control who can view technical drawings and where that data is stored, and export control rules can apply to some drawings. Where that applies, we would restrict access by company and role and keep the upload trail complete.

For most shops, the real care points are customer confidentiality and records retention. Drawings are valuable intellectual property, so access should be limited to the buyer's own team, and certificates should be kept with the job they belong to. If you hold a quality certification, the app should support those records without us claiming that certification ourselves.

• Access limited by customer company and role for every drawing
• Export control checks for drawings that fall under those rules
• Certificates linked to the job, heat lot and inspection record
• Upload and download history kept for quality audits

A customer app only works when the office staff use it too. The estimator, the planner and the quality lead should all update the same job record from the start, so the customer does not see one status while the floor sees another. We would run a trial with a handful of repeat customers before opening it to every account.

For buyers, the first message should come from the account owner, not from a generic system email. It should explain what the app shows, how to upload a revised drawing and where to ask a question. After that, the reminders should be limited to real events such as a quote ready for approval or a cert available to download.
