Lift Installation Payment Milestones: Stop Funding the Builder's Project

By Mr. Sumeet Katariya, ElevatorPlus ·

In short: Lift installation payment milestones should follow your cash out, not the builder's progress. You pay for material weeks before erection, so the largest payment should fall at or before material delivery, not at handover. Tie every milestone to an event you can prove with a document the builder signed. Avoid triggers you do not control, such as building occupancy. Then track each milestone weekly: the event date, the invoice date, the due date and the payment received.

Key takeaways

If most of your money arrives at handover, you are lending to the builder. Material, labour and transport are paid long before the lift is handed over.
Every milestone needs a trigger you can prove. A signed challan, a signed checklist or a signed test report. Not "on completion of work".
Never tie a payment to an event the builder controls. "On handover" can stall for months if the flats are not ready. Split commissioning from handover.
Retention is a date, not just a percentage. If the builder holds back a part of the price, put its release date in the same list as the warranty end date.
Milestones only work if someone checks them weekly. Event done, invoice raised, due date set, payment logged, follow-up made.

Why do lift companies end up funding the builder's project?

Because the contract follows the builder's timeline and your costs follow yours. The two do not match.

A lift installation spends money in a fixed order. You place the material order and pay your suppliers. You transport the material to site. You pay an erection team for weeks. Only then do you test and hand over. If the contract pays you mainly at handover, you have carried the whole cost of the lift for the length of the project.

That might be three months on a site that runs well. On a site where the shaft was not ready, or the power came late, it can be a year.

What happens	When you pay for it	When a handover-heavy contract pays you
Material ordered from suppliers	At order or dispatch	Months later
Material delivered to site	At delivery	Months later
Erection team on site	Every week of erection	Months later
Rework caused by site changes	When it happens	Often never, unless agreed in writing
Handover	Small cost	Most of the money

The fix is not a bigger advance alone. It is milestones that sit on the events where your money goes out.

Which payment milestones should a lift installation contract have?

Use named milestones, each tied to an installation stage. The names matter more than the percentages, because the name tells everyone what has to be true before the money is due.

Milestone	Trigger event	Evidence you hold	Who controls the trigger
Booking advance	Order signed	Signed order or work order	Builder and you
Drawing approval	Layout drawing signed	Signed drawing with revision number	Builder
Material at site	Material delivered and received	Delivery challan signed by the builder's storekeeper	You, once civil is ready
Erection complete	Mechanical and electrical work done	Erection check sheet, dated site photos	You
Testing and commissioning	Lift runs through your full test routine	Signed test report	You, once permanent power is connected
Handover	Lift handed over in working order	Signed handover letter	Builder
Retention release, if any	End of the agreed defect or warranty period	Handover letter date plus the period	The calendar

The percentages against each milestone are a commercial decision. For example, 30/40/30 across advance, material and commissioning is one structure. It is an illustration, not a recommendation. Use what your contracts and your customers support.

What matters is the shape. The money should be weighted towards the milestones you control and the ones where your cash goes out. The stage-by-stage sign-offs behind these triggers are in Lift Installation Stages in India: From Site Survey to Handover, and Who Signs Off Each One.

How should a milestone trigger be worded?

A trigger should describe an event that happened on a date, proven by a document. If two people can disagree about whether it happened, it is a weak trigger.

Weak trigger	Why it fails	Stronger trigger
"On completion of work"	Nobody agrees what "complete" means	"On the signed test report"
"On handover" alone	The builder decides when to accept handover	"On testing and commissioning", with handover as a separate, smaller milestone
"On occupancy of the building"	Depends on the builder's sales, not your work	Remove it. Tie the payment to your own stage
"On receipt of lift licence"	The statutory step differs by state and is not in your hands	Tie the payment to your test report. Handle the statutory step as a separate line
"Material payment after erection"	Your supplier is paid months before	"On delivery of material at site, against the signed challan"
"As per progress"	Progress is an opinion	Name the stage and the document

Two warnings. First, contract wording and enforceability are questions for your lawyer, not for this page. Second, a strong trigger only helps if you collect the evidence on the day. A challan signed three weeks late is a three-week delay in your cash.

What about retention money held by the builder?

Some builders hold back part of the price until the end of a defect or warranty period. Whether you accept that is your commercial call. If you do, treat retention as a dated receivable, not as money you will remember to chase.

Retention is the payment most often forgotten. The project closed a year ago, the site team has moved on, and nobody owns the last invoice. Put the retention release date in the same list as the warranty end date. They usually fall on the same day, and both start from the handover letter.

Record at handover	Why
Handover date	Starts the warranty and the retention clock
Warranty end date	The day the AMC should start
Retention release date, if any	The day the last payment falls due
Name of the person who will release it	Builders change accounts staff too

Plan the AMC conversation and the retention collection together. A builder who is about to sign your AMC for the society is more likely to release retention on time.

What happens to payments when the site stalls?

Stalls are where installation cash disappears. The shaft is not ready, permanent power has not arrived, or another trade blocks access. Your team leaves site. Your material sits in the builder's store.

Three things protect you when that happens:

The material milestone has already been paid. If you were paid at delivery, a stalled site costs you time, not cash.
The stall is in writing. Record the date, the cause and who owns it. "Erection stopped, no permanent power, builder informed by email" is evidence. A phone call is not.
Remobilisation is priced. If your team has to leave and return, agree in the contract what that costs. Talk to your lawyer about the wording.

The worst position is a stalled site, material delivered but unpaid, and an erection team waiting. That is the position a handover-heavy contract creates.

How do you track installation milestones once the project is running?

With one list across all projects, reviewed every week. One row per milestone, not per project.

Column	What goes in it
Project and lift ID	Which job and which lift
Milestone	Booking advance, material at site, erection complete, and so on
Event date	When the trigger happened
Evidence	Challan, checklist, test report or handover letter reference
Invoice date	When the invoice was raised in your accounting software
Due date	When payment is due under the contract
Received	Amount and date of each payment, including part payments
Next follow-up	Date and owner of the next collection call

Run the review every Monday. It takes four questions:

Question	What it catches
Which events happened last week with no invoice raised?	Money earned and not billed
Which invoices passed their due date?	Money billed and not paid
Which milestones are blocked by the site?	Stalls that need a written note today
Which retention dates fall in the next 60 days?	The payment everyone forgets

The first question finds the most money. The event happened, the evidence is signed, and nobody told accounts.

Payment management in ElevatorPlus logs every payment received and the next due date. ElevatorPlus reminds your team when a collection follow-up is due. The invoice itself stays in whatever invoicing software you already use; ElevatorPlus never creates invoices. It keeps the receipts of payments collected, and your team can upload any file, invoices included, to Important Documents so the paperwork sits with the project. Tally is live, and other platforms connect through our open API.

Project management tracks plan dates against actual progress for each installation stage, with site photos and remarks from the team on site. The photo and the date for the event sit next to the stage, ready when the builder asks for proof.

Frequently asked questions

1. What are typical payment milestones for a lift installation in India?

Common named milestones are booking advance, drawing approval, material at site, erection complete, testing and commissioning, handover, and retention release if the builder holds retention. The split between them is a commercial decision for each contract.

2. What percentage should the advance be for a lift installation?

There is no standard figure. For example, 30/40/30 across advance, material and commissioning is one structure. Use what your contracts and customers support, weighted towards the milestones where your cash goes out.

3. Why should lift material be paid for at delivery?

Because you pay your suppliers before or at dispatch. If the material payment waits until erection or handover, you carry its cost for the length of the project.

4. Should a lift payment be tied to handover?

Keep handover as a separate, smaller milestone. The builder controls when handover happens. Tie the larger payment to testing and commissioning, which your own signed test report proves.

5. How do I stop retention money being forgotten?

Record the retention release date at handover, next to the warranty end date, with the name of the person who will release it. Review it in the same list as every other milestone.

6. Is this legal advice on installation contracts?

No. Contract wording and whether a clause can be enforced are questions for your lawyer.

7. Does ElevatorPlus raise installation invoices?

No. Invoices stay in whatever invoicing or accounting software you already use. ElevatorPlus logs every payment received and the next due date, keeps the receipts of payments collected, and reminds your team when a collection follow-up is due. You can upload any file, invoices included, to Important Documents.

Most lift companies price an installation carefully and then accept a payment schedule that makes them the builder's bank. The margin on paper is fine. The cash in the account is not.

Move the money to where your costs are. Material at site, testing and commissioning, and a small, separate handover milestone. Every trigger backed by a document the builder signed.

Then check the list every Monday. An event with no invoice is money you earned and did not ask for.
