It is a little tricky to give advices, since you do not mention what your business.  Do you manufacture a product to deliver to your customer? Or are you trading only?  I assume you manufacture in my answer.  With all this I advice to set all product with traceability to lot numbers.

1. What is the relation with the client reference? Order, product, Batch, lot?  Can be straight forward to keep track on or difficult.

2. Perhaps use variants for sales products. I would recommend different products for each vendor.  Then you can have different BOMs related to each variant with the corretc vendor for each.

3. What kind of revisions?  Change in specifications?  Or Quality checks.  There are many thing that can be revised.  So not easy to give advice on that.

4. Specific batches? I assume that this is batches of raw materials from a specific manufacturer?  In that case a MTO process might help you to ensure that it is correct.  Can be set up so you send a specific purchase order to you supplier specificy the batch to be delivered.  That batch will then be reserved directly to your manufacturing order and sales order.

Hope this helps you on the way.
