ERPNext already models your processes: quotes become orders, orders become invoices, receipts become stock. What it does not do on its own is the glue between those steps — the follow-up emails, the handoffs, the exceptions. That glue is exactly what the vibe-code agent on your OpenSysLab server can build. It reads the configuration, writes scripts, and wires documents together, and every rule it creates can be reviewed before it runs. Here are ten workflows worth automating.

1. Quote-to-cash with follow-ups

Quotations die quietly when nobody chases them, and invoices age the same way. The agent builds the full chain: a quotation converts to a sales order, the order becomes a delivery note and an invoice, and scheduled notifications nudge owners when a quote sits untouched or an invoice passes its due date.

Say “When a quotation is open for more than 7 days, email the assigned salesperson a reminder with the customer name, the total, and a link to the quote.” The same pattern extends to invoices, so dunning stops being a guilt trip and becomes a schedule. Your pipeline stops depending on memory.

2. RFQ to purchase order

For regular purchasing, the agent can wire the buying chain end to end: an approved material request triggers a request for quotation to your approved suppliers, incoming supplier quotations land in one comparison, and the winning line becomes a purchase order.

Try “When a material request for packaging is approved, send RFQs to our three packaging suppliers and summarize their quotes in a comparison table for me.” You pick the winner; the paperwork handles itself, and the quoted prices stay attached to the purchase order for the receipt to check against.

3. Make-to-order production

If you manufacture, a confirmed sales order should start production without anyone re-keying it. The agent connects the chain: production plan, work orders for each bill of materials level, job cards for shop-floor time, a finished goods receipt, and a message when the item is ready to ship.

Ask “When a sales order includes a manufactured item, create the work order automatically and notify me when all its job cards are complete.” If a raw material is short, the work order says so up front, and the agent can raise the purchase request for it. Production status stops living on a whiteboard.

4. Low-stock replenishment that runs itself

ERPNext tracks reorder levels per item and warehouse and can raise material requests on its own, but most installs never switch that on. The agent sets the reorder and safety-stock numbers with you, enables automatic material requests, and drafts purchase orders against each item’s default supplier.

Say “For my top 50 items, set safety stock from the last 6 months of sales and raise a purchase request automatically when projected stock drops below it.” Stockouts stop being a surprise, and the draft POs arrive in your inbox for a one-click review instead of an evening of list-making.

5. The monthly payroll run

With the HRMS app installed, payroll is a fixed monthly pipeline: attendance flows into a payroll entry, salary slips generate, and a bank summary goes out for payment. The agent can install the HR app if it is missing, configure salary structures once, then automate the cycle.

Try “At month end, pull attendance into payroll for my 12 staff, flag unexplained absences before generating slips, and prepare the bank payment summary.” Exceptions come to you; the routine runs itself. Payroll is one workflow where you should insist on reviewing the draft slips before anything is submitted.

6. Expense approvals with real states

By default an expense claim is just a document. The agent attaches a workflow: the employee submits, a manager approves anything over a threshold, accounts pays, and both sides get an email at each transition. The full history stays on the document, which auditors appreciate.

Say “Add an approval workflow to Expense Claim: anything over 200 dollars needs manager approval, and email accounts when a claim is approved.” You can draw the same pattern on purchase orders or leave applications later.

7. A quality gate on goods receipt

Receiving bad stock silently poisons your sellable inventory. The agent links quality inspection templates to item groups, so a receipt for those items cannot become sellable stock until an inspection passes — failed lots can route to a quarantine warehouse automatically.

Ask “Require a quality inspection for everything in the Electronics item group before it enters sellable stock, and email the checklist to our QC person when a receipt arrives.” Defects get caught at the dock, and the supplier dispute has a dated inspection record attached.

8. Batch expiry alerts

If you stock perishables or chemicals, batches carry expiry dates that quietly become write-offs. The agent switches on batch tracking for the right items, then schedules a daily check for batches nearing expiry with their remaining value, so you can discount or repurpose stock before it dies on the shelf.

Say “Every Monday, list batches expiring in the next 60 days with their on-hand quantity and stock value, oldest first.” Write-offs shrink when you see them coming, and picking can favor the earliest-expiry batch so old stock moves first.

9. Timesheet to invoice

Services businesses bill hours, and hours live in timesheets. The agent wires the path: approved project timesheets roll up at each customer’s billing rate and land as draft sales invoices for your review, with the timesheet detail attached.

Try “Every Friday, draft sales invoices from approved timesheets on the Acme project at 95 dollars an hour and hold them for my review.” Billing stops waiting for someone to assemble it by hand, and the project profitability report starts reflecting reality.

10. Keep your webshop in sync

ERPNext has a REST API and a webhook engine, which is enough to talk to an external storefront. The agent builds a sync: item prices and stock push out to your shop, new shop orders pull in as sales orders, and stock reserves at the moment of purchase so you never oversell.

Say “When stock changes for items tagged Webshop, push the new quantity to my WooCommerce store, and pull new orders in every 15 minutes as sales orders.” Two systems, one truth, and no more apologizing for stock you did not actually have.
