WIP Process – Evaluating Pre-Billed Jobs(New)
WIP Process – Evaluating Pre-Billed Jobs
When Pre-Billings are calculated automatically, JobBag evaluates each Kind on every job:
- It compares the amount invoiced to the client against the value generated on the job.
- Accurate value recording per Kind is essential for correct WIP and Pre-Billing calculations.
How Pre-Billings Are Calculated
With WIP Settings for Income Recognition set to automatic:
- Job status is checked:
- Proposed
- Live
- On Hold
- JobBag evaluates each Kind:
| Scenario | Result |
|---|---|
| Billings > Value | Pre-Billings = Billings − Value |
| Value ≥ Billings | Pre-Billings = 0 |
Example 1 – Basic Pre-Billing
- Invoiced this month: $20,000
- Value generated this month: $8,000
Pre-Billings: $20,000 − $8,000 = $12,000
This $12,000 will be carried over to the next month.
Example 2 – Carrying Over Pre-Billings
- Pre-Billings last month: $12,000
- Invoiced this month: $0
- Value generated this month: $8,000
Pre-Billings this month: $12,000 − $8,000 = $4,000
Example 3 – Adding New Invoice to Existing Pre-Billings
- Pre-Billings last month: $4,000
- Invoiced this month: $10,000
- Value generated this month: $12,000
Total billings to date: $4,000 + $10,000 = $14,000
Pre-Billings this month: $14,000 − $12,000 = $2,000
Handling Value Recorded on the Wrong Kind
Sometimes, value and billings are recorded on different Kinds:
| Kind | Invoiced | Value | Pre-billings | WIP | Write-on | Write-off |
|---|---|---|---|---|---|---|
| Concept | 10,000 | 8,000 | 2,000 | 8,000 | – | – |
| Design | 0 | 6,000 | 0 | 6,000 | – | – |
Adjustment Steps:
- Reduce WIP on the Kind where value was incorrectly recorded.
- Reduce Pre-Billings on the Kind where it is overstated.
After adjustment:
| Kind | Invoiced | Value | Pre-billings | WIP | Write-on | Write-off |
|---|---|---|---|---|---|---|
| Concept | 10,000 | 8,000 | 2,000 | 6,000 | 6,000 | – |
| Design | 0 | 6,000 | 0 | 0 | – | 6,000 |
Net Result:
- Pre-Billings carried over: $2,000
- Write-on (Concept) and Write-off (Design) offset each other
- Revenue correctly reported in P&L: $8,000
✅ Key Takeaways
- Always record value against the same Kind as the invoice.
- Adjust WIP and Pre-Billings if billings and value are misaligned.
- Pre-Billings carry forward until work is completed or billed.
- Write-on / Write-off adjustments do not affect total revenue; they ensure correct allocation per Kind.
