Payment Applications
A Payment Application is your interim valuation — what you're claiming for work done in a period. Bidix tracks the full cycle the Construction Act expects: what you applied for, what was certified, the notices due, and what was finally paid — and it derives every statutory date for you so nothing becomes time-barred. Find them on the job's Payment Applications tab.
The cycle
Submitted → Certified → Paid (or Overdue if the final date passes)
| Field | Meaning |
|---|---|
| Applied amount | The gross value you're claiming this period |
| Certified amount | What the payer certifies as due |
| Retention | Deducted automatically per the job's terms (override if needed) |
| Paid amount / paid date | Recorded on settlement |
The statutory dates
Set the application date and Bidix derives the rest from the job's contract type (you can override any of them). The day counts are:
| Contract | Payment due | Final date for payment | Pay-less notice |
|---|---|---|---|
| JCT / SBCC | application + 14 days | due + 17 days | final − 7 days |
| NEC4 | application + 21 days | due + 14 days | final − 7 days |
| Standard | application + 30 days | due + 14 days | final − 7 days |
The payment notice is due 5 days after the payment due date in all cases.
Worked example — JCT, applied 15 Jun 2026:
- Payment due: 29 Jun (15 Jun + 14)
- Payment notice due: 4 Jul (due + 5)
- Pay-less notice due: 9 Jul (final − 7)
- Final date for payment: 16 Jul (29 Jun + 17)
The list flags applications overdue against the final date for payment (with the number of days), and warns when one is due soon (within 7 days).
Notices and what's legally payable
This is where the Construction Act bites. Bidix works out the notified sum — the amount that must legally be paid — from the notices served and whether they were served on time:
1Notified sum = pay-less notice amount (if a valid pay-less notice was served)
2 → else payment notice amount (if a valid payment notice was served)
3 → else the full applied amount (the payee's right under the Act)
A notice served after its deadline is ineffective, so the amount falls back down the list. From the notified sum:
1Shortfall = max(0, applied amount − notified sum) (what the payer is withholding)
2Net payable = max(0, notified sum − retention) (what's due after retention)
3Outstanding = max(0, net payable − paid amount) (still owed)
Why it matters: if the payer misses both notice deadlines, the full applied amount becomes payable — the "smash-and-grab" right. Bidix tracks those deadlines precisely so you know where you stand.
Cadence
The expected interval between applications is configurable (monthly by default), and Bidix can suggest the next application date from the job's most recent one.
How it feeds the rest of the system
- Applied and certified values drive Value Earned in the CVR.
- Certification and payment dates feed the Cashflow Forecast.
- Retention deducted here flows through to retention release — see the Retention guide.
Tip: Enter the application date and let Bidix calculate the deadlines — then act on the pay-less notice date in particular. For a payer, missing it can mean paying the full claim; for a payee, it's the date your entitlement crystallises.
