Stage the work on invoices.
There is no separate sales-order fulfilment stage screen. Bill a deposit, then raise further invoices for progress or the balance against the same customer. Tracked stock moves when each invoice posts.
Deliver what you can, when you can.
Several invoices against the same customer as the job progresses.
Deposit invoice
Convert the estimate and bill a portion.
Progress invoice
New invoice for the next stage against the same customer.
Time-based
Time Tracking → Timesheet, then invoice unbilled hours from the project.
Keep cash and customers moving.
No fake dispatch
You will not mark 3 of 10 units shipped on a sales order that does not exist.
Projects
Job costing lives under Time Tracking → Projects.
Credit notes
If a stage is cancelled, credit the invoice.
Partial & staged fulfilment: common questions
Is there a fulfilment kanban?
No.
Can I ship part of a tracked SKU?
Invoice the quantity you are billing; that is the stock movement.
Can I keep the rest on backorder?
Keep a note on the customer or project. There is no backorder document.
Where do I convert the quote?
Sales → Estimates → convert to invoice.
Progress billing without a sales-order module.
Estimates, invoices, projects — those are the admin menus.
