A two-sided portal. Your contractors log in to bid against your RFQs, see their work orders, view transmitted drawings, request inspection, submit work-done, upload bills, update bank details. Your back office sees everything land in the same screens they already use — no parallel inbox, no email forwarding, no re-entry.

§ 01
Two sides
One portal · two audiences · five stations

What contractors do.
What we see.

Every step the contractor takes on the portal becomes a record in the back office. No copy-pasting. No email chase. The journey below is the same five-station flow viewed from both sides at once — contractor's actions above the line, your team's view below.

The pillars
Three deep-dives · what the contractor actually does

Quote. Execute. Bill.

Each pillar below is one phase of what the contractor does on the portal. The illustration shows what they see; the text explains what your back office sees. Six menu items split across three pillars.
Pillar · 01 · Quote

Tender Quotation + amendment · online.

You publish an RFQ. The portal pings every onboarded vendor. They log in, see the BOQ, fill quoted rates against each line, attach their commercial terms, click submit. You see the quote land instantly — and the price comparison auto-runs across all bidders the moment the RFQ closes. If they need to revise, Quotation Amendment carries the audit trail.

View Order · drawings · RFI · Work Done.

Once they win, the order shows up in their portal — every line, every term, every drawing transmitted to them. They request inspection when an activity is ready. They submit Work Done — quantity executed, dates, location. Your billing engineer's screen lights up with each submission, ready for the certification chain (DPR, QC, sign-off).

Pillar · 03 · Bill

Bill Inward · approval · payment status.

Once work-done is certified, the contractor uploads their bill via Bill Inward — PDF, supporting docs, GST/TRN-compliant. Your back office sees it land in the AR queue with the certified work-done already linked, retention pre-deducted, escalation pre-applied. The contractor sees status updates as the bill moves through approval, all the way to payment hitting their account. Vendor Bank Update lets them maintain payment details themselves.

And separately…
A different tool · same back-office team uses it

Bills come in from many places.
AI Scan handles them all.

Not every contractor uses the portal. Some still send paper bills, some email PDFs, some couriers a stack of vouchers. Your back office shouldn't care which channel — they should just hit a button. AI Scan is the tool that does that. It's a separate sub-page because it's a separate audience: your back office, not your contractors.
▸ AI Scan · sub-page 05

Paper. PDF. Portal upload.
Same engine.

Upload a scanned bill, an emailed PDF, a portal-submitted file. AI Scan reads it, extracts header + line items, matches them to the work order, drafts the RA bill against the certified work-done, flags discrepancies. The back-office team reviews and approves — they don't re-key.

Where to go next.

The portal is the contractor-facing surface. The other sub-pages cover the spine, the LMP rhythm, drawing management (which transmits drawings to the portal), AI Scan, and BIM Revit BOQ.
Before the portal, my procurement team's mailbox was the bottleneck. Vendors emailing quotes, calling for status, couriering bills. Now the portal is the inbox — and the inbox is the system. The thing I didn't expect: vendors prefer it. They can see exactly where their bill is, exactly when it'll be paid. Our supplier relationships got better.

Next step

See both sides
of the portal.

30 minutes. We'll show your back office's view of an active RFQ, then jump into a contractor's login and walk the same RFQ from their side. Submit a quote. View an order. Request inspection. Upload a bill. Watch it land back in your queue without a single email.
