I’ve worked extensively with automation systems that mirror the type of workflow you’re describing here. In my experience building solutions with tools like n8n, Gmail API, and Google Drive API, I’ve set up automations that parse incoming data, apply custom date logic, and then organize or store files dynamically. For example, I’ve designed end-to-end automations for clinics and CRMs where inbound data was parsed from calls or emails, organized into structured formats, and then pushed to the right folders or pipelines. I’ve also handled recurring scheduled tasks like monthly folder zipping and automated dispatches, so I understand how important it is to get both the logic and reliability right for long-term use. Your use case for invoice sorting, non-standard date periods, and monthly zips aligns closely with the workflows I’ve delivered before. Happy to connect and share insights from my experience if it’s helpful.
