Complete the questionnaire

Follow the form from top to bottom, question by question

05
This section follows the form from top to bottom. The question numbers below are the same numbers you see on your screen. Work through them in order and click Save draft often.
Form §1

Section 1 – General Supplier Common Information

Where: The top of the form, under 1 General Supplier Common Information Questions.

YOUR SCREEN This is what Questions 1.1 to 1.7 look like. Fill them in using the instructions below.

What you see: Questions 1.1 Jurisdiction to 1.7 Website. Some answers are already filled in by Aecon.
1.1

Jurisdiction

This refers to the location country of your remit-to (payment) address. It is usually filled in already. If it is filled in, do not change it without asking your Aecon buyer.

1.2

Request Type

If it is already filled in, do not change it. The most common answer is New Supplier / Remit to, even if you already supply Aecon. If it is empty, ask your Aecon buyer what to select.

IMPORTANT:

Choosing the wrong Request Type causes delays because your registration will be sent back to you at the end of the review, and it will have to go through all the approvals again.

1.3

Legal Supplier Name

  • This is filled in with the name you provided to the buyer or the name we already have in our system. Check that it matches the name on your tax document exactly, including endings such as Ltd., Inc. or LLC.
  • If you invoice under a different trade name (DBA), you must insert it before the legal name, in the same box. Then attach a document linking both names in Question 14 or 15.
  • Remove accents and special characters (for example, type “e” instead of “é”). Most banks cannot process them.
  • If the prepopulated name is very different from your company’s name, contact your buyer before you continue.
IMPORTANT:

If the name here does not match the name on your invoices, your invoices will not be processed.

1.4

Supplier Contact Email

Your company email address. Do not use an Aecon email address.

1.5

Business Contact Name

The person Aecon can contact about this registration. Aecon may call this person to confirm the details.

1.7

Form §1.8

Section 1.8 – Tax Information

Where: Still in Section 1, under 1.8 Tax Information. Have ready: your tax document.

1.8.1

Does Your Company Have a Government Tax Identification Number?

Your form shows one of two versions of this question. Answer the version you see:

If your screen asks…Answer
Version 1: “Are you Tax exempt?”No if you have a federal or national tax ID (this is the usual answer). Yes only if you do not have a government tax ID. This question is not about U.S. tax-exemption certificates.
Version 2: “Does your company have a Government Tax Identification Number (Tax ID Registration)?”Yes if you have a federal or national tax ID. No if you do not.

EXAMPLE Version 2 of the tax questions, filled in for a Canadian supplier.

What you see: 1.8.1 answered Yes. 1.8.3 shows Country/Region Canada (CA) and the GST number 123456789RT0001. 1.8.5 shows the attached file.
1.8.2

Reason for Tax exemption

This appears only if you said you have no tax ID. Explain why you cannot provide a federal or national government tax ID. (This question is not about U.S. tax-exemption certificates)

1.8.3

Tax Number(s) – Add Each Tax Number

First select the Country/Region. Then type your tax number in the Tax Number box. It must match your tax document.

Where your company isWhat to enter
CanadaGST/HST number in this exact format: 123456789RT0001 (9 digits + RT + 4 digits). Aecon collects and remits GST/HST, which uses the CRA program code RT, so use this format only.

United StatesYour W-9.
Other countriesA similar document from your government tax agency.
IMPORTANT:

The document must show the same tax number and the same company name (legal name or DBA) that you entered. If your DBA is not on the tax document, attach a government document linking both names in Question 14 or 15.

1.8.6

Will You Perform Subcontracted Work on an Aecon or Aecon JV Site?

Answer Yes or No. If you already have a supplier ID with Aecon, ask your buyer whether your account is set up as a subcontractor (SUB) before you answer. Changing this answer will overwrite the SUB settings in Aecon’s system.

  • U.S. suppliers: if the proof of address document does not show the full 9-digit ZIP code, attach an additional screenshot from the USPS.COM Look Up a ZIP Code in Question 14 or 15.
