A project cannot advance while its checklist still has open items.

A rooftop installation is not one thing: it is fifteen working stages, plus Complete and Cancelled once it is over, seventeen in total. Documentation verification happens first, typically a single day, then name resolution if the customer's name needs to match across paperwork. A loan-backed deal adds four stages here (application, document submission, sanction and disbursal) before the file moves on; a cash deal skips past them entirely. Loan sanction is the visible bottleneck — at one Delhi-NCR EPC we work with, it is the slowest stage in the pipeline, and that is the bank's calendar, not yours. Site survey comes next, then either structure dispatch (cash) or material dispatch straight through (loan), then installation, pending payment, net meter activation, WiFi setup and invoice creation carry every project the rest of the way. Tasks exist only inside these stages, and every stage has its own checklist.

The checklist itself branches. Loan tasks appear on loan projects only; subsidy tasks only on PM Surya Ghar or GBI projects. Net metering paperwork changes depending on whether the customer sits under BRPL, PVVNL, DHBVN, TPDDL, BYPL, UHBVN or NPCL — the seven DISCOM boards Solar Spine knows by name. Nobody types these tasks. Nobody decides when they are due. The moment a project enters a stage, Spine writes the complete checklist with calendar due dates already on it, and a stage cannot roll forward until every open item is closed.

This is not a time-wasting process gate — it is the only thing that stops you from discovering in month three that a customer skipped straight past site survey because the month was busy. The gate stays free to roll back or cancel a project; it only stops you from pretending work is finished when it isn't.

A reminder can be ignored on a bad day. These three cannot. The stage gate stops you from moving a project forward while its checklist has open items. The payment gate prevents dispatch and net meter activation until the money actually arrives: the defaults are 25 per cent collected before structure dispatch, 65 per cent before material dispatch on a loan-backed deal, 95 per cent on a cash deal, and 100 per cent before net meter activation or completion. A director can change these thresholds for their own workspace; they are the numbers the first customer ran, and every new workspace starts on them until it sets its own. The document gate holds a document as done only when ops marks it correct, not when someone ticks a box.

The salesperson photographs the customer's papers on their phone the moment the sale closes. Documentation marks each file right or incorrect; incorrect files get a reason and go straight back to the photographer, not into a folder nobody opens. Cheque bounces reopen the instalment instead of disappearing into a bank statement nobody reconciles until quarter end. The system holds the project and the payment schedule in the same place, so what you invoiced and what you agreed cannot drift apart.

Once you set these gates, they are not negotiable. You cannot call the material dispatcher and talk them into sending panels early on a promise. The button to move the project forward is simply not available until the money lands and the documents verify.

At 7:00 am, before anyone is in, overdue instalments have already gone to whoever is responsible for collections and to their manager. Anything that went late last night has already climbed a rung up the org chart. No one opened anything to make that happen. At 9:00 am, each of the nine roles opens its own screen. Each person sees exactly their work for the day: what is due today, what is late, who has too much and who has nothing. Documentation ops sees the files waiting on verification, a target, and overdue items by name. The telecaller sees a calling list that is already built and already ordered. Delivery sees dispatches. The director sees the whole book by stage, by person, and what it is worth in kW.

All day, a project cannot stall silently between two departments. A stuck stage is an open item with a name and a date on it. If that date passes, it goes looking for someone more senior. The week that is left is for growing the business, not chasing status. Month-end is one list, not six — every rupee due this month sits in one place, beside kW installed and net meters activated.
