Automate bookkeeping workflows and supplier-delay emails
Commenters used n8n to automate bookkeeping firm workflows, saving about 600 hours a year, and to email customers automatically when supplier lead times changed.
Done withn8n
- What they did
- One commenter said a bookkeeping firm paired n8n with new pre-accounting software: the software handled the accounting side, while n8n automated document management and chased clients for missing items. Another described an ERP-Shopify pre-order flow that pulls supplier-confirmed delivery dates from purchase orders and automatically emails waiting customers when lead times change, with cancellation offered if dates move.
- How it went
- The bookkeeping setup saved about 600 hours a year directly, and the firm said it could quadruple its client list without another hire, framed as roughly 2,400 effective hours and close to $30,000 in wage savings. The pre-order system was only recently live, so they shared no final revenue or time-saved numbers yet.
- Worth knowing
- The bookkeeping commenter said the gains did not come from n8n alone; they depended on introducing new pre-accounting software alongside the workflows.
Try it yourself with n8n
Build an n8n workflow for my [business type] that handles [repetitive task, e.g. collecting client documents and sending invoice reminders] automatically. Also add a flow that watches [supplier sheet/email] for lead-time changes and drafts an email to affected customers. Have it draft customer emails for my approval before sending anything. Done means both workflows run successfully on test data and I get a short note on the time saved per week.
