Raise milestone invoices and get paid on time
To get paid on time, link every invoice to a milestone written in the agreement, raise it the day that milestone is reached, and record each part-payment against it. Send reminders on a fixed schedule with the invoice attached. Track every material, labour and vendor cost against the project so you see profit while the job is running, not after handover.

Agree the payment schedule before work starts
Every invoice problem traces back to a vague agreement. Before taking the booking amount, write down each milestone, its share of the contract value, the visible event that triggers it and the payment terms. Include how change orders and delays are billed. When the client signs this schedule, later reminders become routine rather than awkward, and your team knows exactly when to invoice.
Raise milestone invoices the day a stage is done
Interior payments slip when invoices go out late. The milestone should be visible on site, such as carcass installed, so the client cannot dispute it.
- Copy the milestones and percentages from the signed agreement into an invoice schedule.
- Define each milestone by a visible event, with a site photo as proof.
- Raise the invoice on the same day the supervisor confirms the milestone.
- Include any approved change orders on that invoice as separate lines.
- Issue a proper GST invoice and confirm the GST treatment of your contract with your CA.
In the D&B Operating System, milestone invoices with GST follow the payment schedule set in the agreement.
Track every client payment, including part-payments
Clients often pay in parts over UPI, bank transfer and cheque. Without a ledger per project, balances get confused.
- Keep one payment sheet per project: invoice number, amount, due date, amount received, date, mode, balance.
- Match each bank or UPI credit to an invoice the same day.
- Send a receipt for every payment received.
- Review all open balances every Monday with the owner.
The D&B Operating System tracks part-payments and receipts, and shows the owner money due, received and overdue.
Send payment reminders that stay polite
A clear schedule removes the awkwardness. The client knows reminders are routine, not personal.
- Three days before the due date, send a friendly note with the invoice attached.
- On the due date, send the UPI ID or bank details and the amount.
- Three days after, the project manager calls and confirms a payment date.
- After a week, the owner speaks to the client and agrees next steps, including pausing the next stage if the agreement allows.
The D&B Operating System sends payment reminders and lists overdue payments in reports.
See project profit while the project runs
Many firms only learn a job lost money at the end. Track costs against the quoted value every week.
- Set the budget per project from the BOQ: materials, factory, labour, vendors, transport.
- Log every purchase order, vendor bill and labour payment against the project.
- Compare actual cost to budget each week and flag any line over budget.
- Profit is the invoiced value, including change orders, minus actual costs.
- Review profit by project each month to see which project types earn the most.
In the D&B Operating System, vendor bills and expenses sit against each project, with project profitability reports and exports for your accountant.
