How do I make a return reduce the job's cost?

Record the credit as its own entry tagged to the same job as the original purchase, then note the net cost (original minus credit, minus any restocking fee). The two records sit side by side so the job's recorded material cost reflects what you actually kept.

Where should the credit memo live?

Attach the supplier's credit-memo document or return receipt to the return record inside the job's folder, so the proof and the entry stay together for month-end and year-end review.

Does Cash Workspace calculate the net cost for me?

You record the original amount, the credit, and any fee, and note the net yourself. Cash Workspace keeps those records and the attached credit memo organized in one place for your review — it does not compute profit or margin.

Keep material returns and supplier credits tied to the job

You over-buy a few boxes of tile, a couple of fittings, an extra bundle of shingles — then return them and the supply house issues a credit memo. If that credit never gets recorded against the original purchase, the job's recorded material cost stays too high and the credit memo goes missing by the time your bookkeeper asks for it. Cash Workspace gives you one place to record the return, attach the credit document, and note the net cost so the job's records match what you actually spent.

The problem

Why returned materials throw off job costs

A return is two events — the original purchase and the credit — and most trades only ever record the first. Without the credit recorded against the same job, the cost on the books overstates what the job really used.

The original $1,400 lumber receipt is recorded, but the $260 return credit never is, so the job looks $260 more expensive than it was.
A supply-house credit memo lives in the truck door or a text thread instead of the job's folder.
Returns from two different jobs hit the same account, and the credit gets applied to the wrong job.
By the time you reconcile the supplier statement, nobody remembers which return matches which purchase.
Restocking fees are forgotten, so the net credit you actually received doesn't match what's recorded.

The workflow

Record a return and its credit against the original purchase

Treat every return as a credit recorded against the purchase and job it came from, with the credit document attached.

1
Find the original purchase
Open the original material expense record — the receipt for what you bought and which job it was tagged to.
2
Record the return
Add a return/credit record tagged to the same job, noting the items returned and the credit amount the supplier issued.
3
Attach the credit memo
Attach the supplier's credit-memo document or return receipt to the record so the proof sits with the entry.
4
Note the net material cost
Write the original amount, the credit, any restocking fee, and the resulting net cost in the notes so the job's true material cost is clear.
5
Confirm at statement time
When the monthly supplier statement arrives, check that the credit shows up and matches the recorded amount.

Record structure

What to record for each return

A few consistent fields keep the return tied to the purchase and the job, and make the net cost easy to read later.

Linked original purchase: A note pointing back to the original receipt/expense record this credit reverses.
Job tag: The same job the original purchase was tagged to, so the credit reduces the right job's recorded cost.
Supplier: The supply house or vendor that issued the credit, as a consistent vendor name.
Items returned: What went back — e.g. 3 boxes of 12x24 tile, 1 case of PVC couplings.
Credit amount: The dollar value of the credit memo as issued.
Restocking fee: Any fee deducted from the credit, so the net credit recorded is accurate.
Net material cost note: Original cost minus net credit, written in the notes for quick review.
Credit-memo document: The attached credit memo or return receipt PDF/photo proving the credit.
Date: When the return was processed, so it lands in the right month and fiscal year.

Common mistakes

Mistakes to avoid

Recording the purchase but never the credit, so the job's cost stays overstated.
Filing the credit memo somewhere other than the job it belongs to.
Forgetting the restocking fee, so the recorded credit is bigger than what you actually got back.
Applying a credit to the wrong job because two jobs bought from the same supplier the same week.
Leaving the return undated, so it's hard to match against the monthly supplier statement.
