Automate invoice checks and supplier orders in one CRM

A business owner built tools that matched supplier invoices, tracked cost changes, and handled ordering and client billing from one place.

Done with Custom agent· Intermediate

What they did
They used a custom AI setup to build internal workflows instead of handing off the whole process. One tool handled bookkeeping by comparing supplier invoices, flagging pricing shifts, and surfacing freight-cost changes. Another custom CRM turned call notes into mailers, let them place supplier orders, and pushed client invoices through the Zoho Books API.
How it went
They described the system as a single hub for orders and invoicing, and said it saved them a lot of time. No figures were shared for speed, savings, or error reduction.
Tips
This kind of setup works best when you split the job into small tools with clear handoffs. For anything that changes invoices, sends orders, or records payments, make the agent pause and ask before it acts.

Help me build a workflow for [business process]. First, review my source files and list the tasks that can be automated and the ones that should stay manual. Then draft a setup that can compare [supplier invoices] with [purchase orders], report price and freight changes, and prepare client invoices in [billing system]. For the CRM part, turn [call notes] into draft mailers and draft supplier orders from [supplier list]. Stop and ask for my approval before you send an order, create an invoice, delete a record, or change any live data. Show me the draft output and the exact action you want to take before you do anything irreversible.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
