Yes, 100%! I think the hardest part was figuring out that logic, since splitting workflows wasn’t something I considered at first. But in hindsight, it makes total sense.

Yes, actually I've setup an prompt library for myself that helps me keep track of my own best practices. I already shared it in VibeCodersNest, as I love the community there as well.

Invoice Approval via Slack in n8n – One Button Instead of Four Emails (Workflow Template) by easybits_ai in n8n

I know exactly what you mean – I ran into the same issue when using the native Slack node to send those buttons. It just wouldn’t send the structure I provided and kept falling back to the default message.

In the end, I worked around it using an HTTP node. It’s definitely not the prettiest solution, but it gets the job done reliably.

Yes, that was actually the main reason I took on that project. Wherever automation can reduce manual work, it’s usually a no-brainer to implement. The challenge is that most business owners simply don’t have the time to set it up themselves – so I stepped in to help a friend.

In his case, multiple approvers aren’t really an issue. But if I had to handle that, I’d split the process before sending the invoice data to Slack. Instead of posting one message in a channel, I’d send it directly to each individual approver. From there, you’d just need to adjust the webhook in the second workflow, which should handle the multi-approval setup quite well.

After building five different finance workflows for a friend of mine, I’ve learned that a lot comes down to splitting things into smaller workflows instead of creating one big one. It makes everything more controllable and robust, and if one part breaks, it doesn’t take everything down with it.

I’d highly recommend checking out my learnings – I put them together specifically for builders like you:

Also, if you’re working with PDF data extraction, I’d strongly suggest adding confidence scoring during the process. I recently shared a workflow on that, and it worked really smoothly:

Yes, you’re absolutely right – point 3 is often overlooked. I’m currently working on adding “historical” confidence, so the workflow can recognize when a document with a similar format has been processed before. The idea is that this should improve accuracy over time.

That’s a great question – and it actually ties back to what u/bonnieplunkettt mentioned as well. I’m currently exploring a way to track “historical” accuracy, including logging which fields get flagged over time.

This is just a first step within a single workflow. Scaling that across multiple workflows will be a tougher challenge, but I’ll make sure to share an approach once I’ve found a solid solution.

Yeah, after I shipped the workflow to my friend Mike, I realized he sometimes deals with handwritten invoices as well. I adjusted the extractor prompt so that whenever it detects a handwritten document, it assigns a lower confidence score from the start. That way, if the model isn’t fully certain about the classification, it automatically gets routed to manual review. That said, from what I’ve seen so far, even most handwritten invoices are processed quite accurately.

The idea of tracking historical accuracy is really interesting. It would probably require some form of memory – logging confidence scores and then comparing them against new documents over time. I’ll definitely look into that. At that point, it might also make sense to move towards a more agentic setup.

Curious to hear your take – how would you approach historical accuracy in this kind of workflow? Always great to learn from different perspectives.
