From submitting your prequalification to sending an invoice or finding a bid opportunity — all resources are in one place. Jump directly to the section you need.
Olive Tree Builds uses a structured bidding process for all subcontract work. If we would like you to bid on a project, you will receive an invitation directly via email from our project team.
Complete our prequalification process to be added to our approved vendor list. This is required before receiving bid invitations.
When a project matches your trade and region, our project team will reach out directly with an invitation to bid, including drawings and scope documents.
Review the scope, ask questions during the RFI period, and submit your bid by the specified deadline. All bids must be submitted in writing.
Successful bidders will be notified and issued a formal subcontract agreement. Review, execute, and submit required insurance documents before mobilizing.
Live Bid Board Coming Soon
We’re building a live bid board where prequalified trade partners can view and respond to open opportunities. Complete your prequalification now to be first in line.
All subcontractors and vendors must be prequalified before receiving bid invitations or being awarded work. Prequalification is valid for one year from the date of approval.
After submitting your request, our team will send a secure upload link for document submission.
Use this form to request a new prequalification, renew an existing one, or check your current status. Our team will follow up within 5–7 business days.
Use the contacts and requirements below to submit invoices and statements. Our AP system reads and routes invoices automatically — formatting requirements must be followed exactly to avoid processing delays.
For larger subcontracts, invoices are processed through our payment portal. Invoices submitted through the portal do not need to be emailed separately. Your project manager will advise which method applies to your contract.
For invoice files only. Cannot process correspondence or inquiries.
Questions about your account or invoices. Response within 48 hours.
All invoices must be submitted in PDF format — one invoice per file
Invoice must include the 6-digit Olive Tree project number (provided in your subcontract)
Invoice must include your company legal name, address, and HST registration number
Progress billing invoices must reference the approved Schedule of Values line items
Any backup documentation (delivery receipts, time sheets) must be combined into the same PDF
Do not send the same invoice to multiple email addresses — this causes duplicate processing
Invoices submitted through our payment portal do not need to be emailed separately
Invoices that do not meet formatting requirements will be returned unprocessed. This may delay payment. If you have questions about formatting, contact [email protected] before submitting.
All subcontracts are governed by the Ontario Construction Act. Statutory holdback of 10% is retained on all progress payments and released 45 days after the date of substantial performance, provided no liens have been registered against the project.
