Invoice-to-Job Automation for a Roofing Contractor

Supplier invoices read from email and attached to the right job in the CRM automatically, with only the ambiguous ones sent to a person, so material cost is known per job, not at month end.

Verification pending. This write-up describes what was built and how it works. It contains no performance figures, and it will be updated with measured results once they are verified.

Challenge

Supplier invoices for shingles, underlayment, flashing and dumpsters arrived by email all month. Material cost per job was a month-end reconstruction, which meant a money-losing job was discovered after it closed.

Existing workflow

Invoices sat in the inbox until someone had time to key them into the CRM, often against the wrong job, sometimes not at all.

What we built

An automation that reads supplier invoices as they arrive and attaches each one to the right job in the CRM, so material cost shows up on the job the week it’s incurred. Anything it can’t match with confidence goes to a person.

Human involvement

People resolve every exception and approve every payment. The automation never pays a bill or edits accounting records.

Result

Built and tested on Certified Contracting’s invoices; not currently running day to day. This case study will be updated with measured before-and-after data before it is marked verified.
