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:

  1. Job status is checked:
    • Proposed
    • Live
    • On Hold
  2. 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:

  1. Reduce WIP on the Kind where value was incorrectly recorded.
  2. 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.
