A finance team needs to know what the proposed screens will cost, which expenses will actually disappear and how any additional contribution will be measured. A claim that screens “save time” is not enough to establish a cash return. Build the case from invoices, staff work records and a limited pilot.
The following single-screen example is entirely illustrative. These figures are budgeting assumptions, not Signmitra prices, supplier quotations or expected customer results. Replace every input with your own evidence.
Key Takeaways
- Keep the full upfront investment separate from annual running costs; depreciation is not the initial cash payment.
- Released staff hours are useful capacity, but they are not payroll savings unless spending actually falls.
- Calculate payback only when ongoing cash benefits exceed ongoing cash costs, and test weaker assumptions.
1. Build the upfront and recurring cost worksheet
On smaller screens, scroll sideways to view every column.| Item | Upfront | Annual recurring |
|---|---|---|
| Display | 25,000 | — |
| Player | 7,500 | — |
| Installation and mounting | 5,000 | — |
| Software allowance | — | 6,000 |
| Paid content work | — | 9,000 |
| Support and maintenance | — | 3,000 |
| Incremental connectivity | — | 2,400 |
| Electricity allowance | — | 3,600 |
| Total | 37,500 | 24,000 |
The first-year cash outlay is therefore ₹37,500 + ₹24,000 = ₹61,500. Use actual incremental costs: if an existing connection needs no upgrade, do not charge the project for the whole office internet bill. If existing staff create content, record the hours separately from new paid work. Include applicable taxes consistently using your finance team's treatment.
Also plan a replacement reserve, for example an illustrative ₹1,800 annually. Money set aside is not itself a supplier payment. Keep the reserve visible in the budget, then put expected replacement purchases into the cash-flow year in which they occur. Do not count both a reserve and the same replacement purchase as two operating expenses.
2. Separate cash benefits from capacity
Assume verified reductions in printing and distribution would save ₹2,500 per month, or ₹30,000 annually. Count only print work that can genuinely stop. Some physical notices may still be necessary.
Suppose a measured promotion could add ten orders per month, each contributing ₹150 after variable costs. That would be 10 × 12 × ₹150 = ₹18,000 annual contribution. This is a hypothetical input, not an assumption that every sale after installation was caused by signage. If a pilot cannot establish additional orders, set this input to zero.
The base-case annual cash benefit is ₹30,000 + ₹18,000 = ₹48,000. Separately, six staff hours freed per month at an illustrative internal value of ₹350 per hour represent 6 × 12 × ₹350 = ₹25,200 of capacity. Exclude that capacity from this cash model unless payroll or contractor spending actually falls. Redeployment alone does not reduce the cash outflow.
3. Calculate first-year ROI and simple cash payback
- Annual net operating cash benefit: ₹48,000 − ₹24,000 = ₹24,000.
- First-year net cash result: ₹48,000 − ₹24,000 − ₹37,500 = −₹13,500.
- First-year cash ROI: (first-year benefits − total first-year cash costs) ÷ total first-year cash costs = −₹13,500 ÷ ₹61,500, approximately −22.0%.
- Simple payback: ₹37,500 ÷ ₹24,000 = 1.5625 years, approximately 18.8 months.
Those results are consistent: a project that pays back after the first year can have negative first-year ROI. The simple payback estimate assumes benefits and running costs occur evenly, ignores financing and discounting, and excludes later replacement purchases. For a purchasing decision, also build a dated cash-flow schedule covering the expected equipment life.
4. Test conservative, base and optimistic assumptions
On smaller screens, scroll sideways to view every column.| Scenario | Cash benefit | Net operating cash | Simple payback |
|---|---|---|---|
| Conservative: ₹18,000 print savings; no additional sales | ₹18,000 | −₹6,000 | No positive payback |
| Base: ₹30,000 print savings + ₹18,000 contribution | ₹48,000 | ₹24,000 | 18.8 months |
| Optimistic: ₹36,000 print savings + ₹24,000 contribution | ₹60,000 | ₹36,000 | 12.5 months |
If the project works only under an unsupported optimistic assumption, reduce its scope or collect better evidence before expansion. A pilot should test the uncertain benefit, such as whether print orders actually stop or a promotion produces additional contribution.
5. Keep an evidence sheet with the proposal
- Attach actual hardware and installation quotations, with the proposed player model.
- List licence terms and renewal assumptions using current published information or a quote.
- Record baseline print invoices and content-maintenance hours.
- Name the owner who will measure any sales contribution and explain attribution limits.
- Review the cash model after the pilot, including costs that were initially missed.
A common mistake is dividing depreciated annual hardware cost by a benefit that includes staff capacity, then calling the result cash payback. Use the full upfront investment and actual net cash flows. A defensible proposal makes its limitations visible and lets the business choose a scale it can support.

Try this with your own screens
Use one representative screen to record setup work, paid content time and the print expenses you could stop. Bring those measured inputs into your cost worksheet before expanding.
