Most interior firms only find out whether a project made money after it is over, when someone finally adds up the invoices and the vendor bills. By then it is too late to fix. Real project profitability for interior firms means a live, project-wise profit and loss that updates as money moves, so you can act while the project is still open.
Why project profitability for interior firms is so hard to see
On a fit-out job, money enters and leaves in dozens of places. Client milestones get invoiced and collected in stages. Vendors bill you for materials and labour. Your own team buys things on site and files reimbursement claims. Each of those usually lives in a different sheet, a different WhatsApp thread, or a different person's head. The result is a familiar feeling: the project is busy, the bank balance looks fine, and you still cannot say whether this project is actually profitable.
The fix is not another month-end report. It is treating every rupee, in or out, as belonging to a project, so margin is a number you can read at any moment rather than reconstruct at the end. That is the idea behind Panzo's project-first Finance view: you land on a list of projects sorted by what is most outstanding, open one, and see all of its money in a single place.
What rolls up into a project-wise P&L
A project P&L is only trustworthy if everyone agrees on how the two sides are built. In Panzo the definition is fixed and the same everywhere in the app, so margin never changes depending on which screen you are looking at.
- Revenue is the contracted milestone value, the stages the client actually signed up to pay. It follows the deal and its payment plan, so it reflects what was agreed, not what you hope to bill.
- Cost is real money out: posted vendor bills, company site purchases, and approved employee reimbursement claims. A claim counts only once it is approved, so the cost side never inflates on unverified spend.
- Margin is simply revenue minus cost, computed live. Because both legs are defined in one place, the margin on the P&L tab is the same figure the rest of the app uses.
Tip
Margin is a delivery tool, not just a report
Reading the Finance overview at a glance
Above the individual projects, the Finance overview answers the two questions that actually keep owners up at night: what are we owed, and what do we owe. It does this with a small set of headline figures rather than a wall of tables.
| Figure | What it tells you |
|---|---|
| Money in | Total collected across projects in the period |
| Money out | Total paid out: vendor payments and reimbursements |
| Net cash | Money in minus money out, your real cash position |
| Outstanding | Invoiced but not yet collected from clients |
| Overdue | The slice of Outstanding that is past its due date |
| Payables | What you still owe vendors on posted bills |
Alongside these sit two worklists, a to collect list and a to pay list, both ordered worst-first. You are not meant to read every row. You are meant to work the top of each list, because that is where the largest or most overdue amounts are.
A project-wise P&L turns "are we doing okay?" into "this project is at 22% and this one is underwater, so here is where I spend my afternoon."
Receivables and payables ageing: the money at risk
Outstanding money is not all equally risky. A bill raised last week is normal. A bill unpaid for two months is a problem. Panzo ages both receivables and payables into current, 1 to 30, 31 to 60, and 60 plus day buckets, and the fiscal year follows your own setting, April to March by default. Ageing is what turns a big Outstanding number into a plan of action.
On the receivables side
The 60 plus bucket is where your working capital quietly gets stuck. Chasing it is not about sending more reminders to everyone. It is about identifying which client and which milestone is sitting in the oldest bucket and dealing with that one first.
On the payables side
Payables ageing protects relationships, not just cash. Vendors who get paid on time quote you better and hold your slots. Seeing what falls due, before it becomes overdue, lets you sequence payments deliberately rather than reacting to an angry call the week before handover.
Turning the P&L into collected cash
A live P&L is only useful if it drives collection. Panzo closes that loop with a clean, auditable flow rather than a spreadsheet of promises.
Work the to-collect list worst-first
Start at the top, the largest or most overdue milestones, instead of chasing whoever messaged you last.Send a WhatsApp payment reminder
The reminder actually messages the customer on WhatsApp before it is marked sent, so a failed send never leaves a false record and you can safely retry without double-messaging.Record the payment with maker-checker
One person records the payment and a different person with the approve permission signs it off. Separation of duties is enforced so no one can invoice, record, and self-approve.Let allocation waterfall
A payment larger than its target milestone fills that milestone, cascades the excess into later invoiced milestones in order, and holds any remainder as a project advance on account.
For genuinely late invoiced milestones, Panzo also shows the interest contractually owed, based on the rate, cap, and grace period in your terms. It shows the figure; it never auto-charges it or blocks work, because pursuing interest is a commercial call. Getting the billing structure right in the first place, covered in our guide to GST and milestone billing, is what makes the whole P&L honest.
Note
What this is not
From visibility to margin discipline
Seeing profit per project changes how you run the firm. A job trending below your target margin is a signal to revisit scope, tighten procurement, or formalise a change order while there is still room to move. A pattern across many jobs is a pricing signal, which is exactly what our playbook on pricing to keep margin is about. Either way, you are deciding on numbers, not on a hunch. When you are ready to see the plans and what is included, the pricing page lays it out, flat per workspace rather than per seat.
Key takeaways
- Real project profitability for interior firms means a live, project-wise P&L, not a year-end tally.
- Revenue is contracted milestone value; cost is posted vendor bills plus site purchases plus approved claims; margin is the same number everywhere in the app.
- The Finance overview answers what you are owed and what you owe with Money in, Money out, Net cash, Outstanding, Overdue, and Payables.
- Receivables and payables age into current, 1 to 30, 31 to 60, and 60 plus buckets, so you can work the money most at risk first.
- Collections use maker-checker approval and waterfall allocation, and late-payment interest is shown, never silently charged.
