Proper Invoice Requirements in New Brunswick
Under the Construction Prompt Payment and Adjudication Act, SNB 2023, c. 15
A proper invoice is the single document that starts the New Brunswick payment clock under the Construction Prompt Payment and Adjudication Act (SNB 2023, c. 15). Get it right and every downstream deadline is anchored and defensible; get it wrong and a payer can argue the clock never started.
New Brunswick has no deemed-proper-invoice rule, so an invoice must contain every required element from the outset. There is no silence-equals-acceptance safety net.

What a proper invoice must contain
New Brunswick proper invoices identify the contractor and the payer, describe the work or materials supplied, state the amount payable and the period covered, give the contract or project reference, and set out the payment terms. Any additional content the contract requires must also be present.
No second chance: get it right the first time
Because New Brunswick has no deeming rule, there is no review window that quietly converts a flawed invoice into a proper one. An invoice that is missing a required element simply does not start the 28-day clock, so completeness on day one is everything.
Why the receipt date anchors every NB clock
Every New Brunswick prompt-payment deadline is measured from the date the proper invoice is received, not the date it is dated or sent. Recording and preserving that receipt date determines when the owner must pay and when every downstream clock expires.
A note on status
New Brunswick's framework is enacted but not yet proclaimed, so these day-counts are working assumptions.
Proper invoice in New Brunswick: FAQ
Does New Brunswick deem an invoice proper if the payer stays silent?
No. New Brunswick has no deemed-proper-invoice provision, so the invoice must be complete and correct from the outset for the clock to start.
When does the payment clock start in New Brunswick?
On the date a proper invoice is received (NB CPPAA s. 10). If the invoice is missing required information it may not qualify, and the clock may not start until the defect is cured.
