Per-job parts records for HVAC technicians and contractors
A compressor swap, a refrigerant top-off, and a thermostat install can all hit the supply house in one run, and refrigerant alone is expensive enough that you can't afford to mis-bill it. Without parts tied to the job and the unit, the customer invoice is wrong and your margin takes the hit. Cash Workspace gives you one place to record each parts run against the job and the unit, with the invoice attached.
The problem
Why HVAC parts get mis-billed
Parts for several jobs come off one supply-house run, refrigerant is sold by the pound, and units aren't noted, so the right parts don't land on the right invoice.
- One supply-house invoice covers a compressor for one customer and filters for three others.
- Refrigerant by the pound gets used across calls and never split correctly.
- A thermostat or capacitor pulled from the truck never gets billed.
- You can't tell which unit a part went into when a customer has two systems.
- Warranty parts and paid parts get mixed on the same record.
The workflow
Record each parts run against the job and unit
Tie every part to the customer and the specific unit while the job is fresh.
- 1
Record at the supply house
After a parts run, record the vendor, date, and amount and attach the invoice before the next call.
- 2
Tag job and unit
Note the customer, job, and which unit — 'Patel — upstairs condenser' — so parts map to the right invoice and system.
- 3
Split shared invoices
When one invoice covers several jobs, make a record per job with its parts and attach the invoice to each.
- 4
Separate warranty from billable
Tag whether each part is warranty, paid by the customer, or shop stock so billing stays correct.
- 5
Pull at invoice time
Open the job's parts records when you bill so every part and pound of refrigerant lands on the invoice.
Record structure
What to record for each parts purchase
These fields keep expensive parts mapped to the right customer and unit.
- Supply house / vendor
- The HVAC distributor, parts house, or big-box store.
- Date
- When the run happened, so it files into the right month and job.
- Amount
- What you paid for the parts on this record, including tax.
- Part type
- Compressor, refrigerant, filters, thermostat, capacitor, or motor.
- Customer, job, and unit
- Who, which job, and which system, so parts map to the invoice.
- Warranty / billable
- Whether the part is warranty, customer-paid, or shop stock.
- Invoice
- The supply-house invoice attached to the record.

Common mistakes
Mistakes to avoid
- Not noting the unit, so you can't tell which system a part went into.
- Mixing warranty and billable parts on one record.
- Forgetting to bill a capacitor or thermostat pulled from the truck.
- Lumping several jobs' parts on one record instead of splitting the invoice.
- Leaving refrigerant unsplit across the calls it was used on.

FAQ
HVAC parts records FAQ
- How do I track refrigerant used across several jobs?
- Record the purchase, then create or note a record per job for the amount used on each, attaching the same invoice. Keeping a refrigerant area in your workspace makes the split easy to see since it's sold by weight.
- Why note which unit a part went into?
- When a customer has more than one system, the unit tells you and the customer exactly which system was serviced. It also helps when the same customer calls back, so you can pull the history for that specific unit.
- Does Cash Workspace extract parts off my supply-house invoice?
- No. You enter the vendor, date, and amount and attach the invoice. Cash Workspace keeps the record and the invoice together against the job and unit so parts are easy to match to the customer invoice.
