Two quotes can have the same monthly figure and buy very different work. Put the service beside the price before treating either proposal as cheaper.
The idea in view · Planning diagram
Normalize price without flattening scope
- Provider unit
- Included duties
- Stated exclusions
- Same period
- Full-cost scenario
- Pending assumptions
Build a common specification
Send every bidder the same view list and schedule. Ask them to mark deviations rather than assume equivalent service. A proposal for overnight alert review is not the same scope as a staffed live viewing position.
Normalize the financial inputs
Choose one currency and a common comparison term. Keep taxes, foreign exchange assumptions and financing separate. Spread setup over that term only for comparison; the actual cash payment may be due immediately. Request usage examples for a quiet and a busy month without treating either as a forecast.
Record unresolved terms
Check minimum commitment, cancellation, renewal, equipment ownership and data export. Price changes linked to activity bands need a definition and a notice process. Rank the fit and the remaining questions alongside price so a cheap incomplete bid does not appear complete.
Compare a quiet month and a difficult one
Use the bidders’ own definitions to build two illustrative bills. For a quiet month, list the recurring fee and unavoidable extras. For a busier month, add a stated number of chargeable events or call-outs using the quoted rules. Label the quantities as assumptions, not expected activity. This is a way to discover a confusing tariff, not to forecast the site.
Keep non-price issues in the same review. A bidder may leave camera support, export rights or a required language unresolved. Mark those cells as pending and give them an owner. Do not enter zero simply to make the spreadsheet calculate. Once scope matches, the financial comparison becomes useful; until then, an apparent saving may just be an omitted duty.
Set one purchasing baseline before collecting prices
Begin with a short requirement that every bidder receives: accepted locations, candidate views, hours, review model, expected activity, escalation duties and any supported local response. State what is still unknown. A bidder may reasonably quote provisionally when the camera system has not been assessed, but the assumptions should remain visible in the comparison. Otherwise the cheapest price may simply belong to the smallest interpretation of the task.
Give each cost a basis. A monthly site fee, a per-camera charge, an event allowance and a staffed viewing hour are different units. Preserve the provider's unit and calculate the total for your stated scenario separately. Do not turn a per-camera headline into a full-site cost without checking minimums, covered hours and additional duties. NightMarshal's own recurring site fee follows an agreed coverage band; it is not a substitute for comparing the complete requirements.
Include implementation and change costs
A quote can omit equipment replacement, installation, network changes, storage, connectivity, configuration, training or a local response agreement. Ask who provides each item and whether it is optional, mandatory or already included. Include one-time charges in the comparison period rather than pretending they are either free or a recurring subscription. Keep the original quote alongside your normalization so the calculation can be traced.
Changes also need a price basis. Ask what happens when a new camera is added, the site opens later, event volume changes or a second location joins. A quiet initial month may not represent later operations. Where a provider cannot price a scenario yet, label it pending and request the missing assessment. Avoid manufacturing an allowance just to make the spreadsheet balance. The uncertainty itself is part of the purchasing decision.
Compare risk allocation as well as the total
Read the scope, responsibilities and exit terms beside the number. Who reports an offline camera? Who pays for repair? What happens if the site cannot supply the agreed connection? Can recordings and incident records be retrieved at exit, and what access needs to be removed? These questions influence the cost of running and changing the service even when they are not line items on the first invoice.
Separate mandatory requirements from preferences. If a provider cannot meet an essential data-access rule or a required duty, an attractive price does not repair the mismatch. Record that result before weighted scoring. If two providers both meet the requirement, price can then be assessed alongside evidence, reporting and implementation effort. Keep a short reason for each judgement so the decision can be explained after the purchasing team changes.
A fictional calculation with a defined comparison period
Suppose one hypothetical offer costs 900 per month with 1,200 setup and another costs 1,000 per month with setup included. Over twelve months, their stated totals are 12,000 and 12,000 before taxes and any excluded work. The first offer's monthly equivalent is 1,000 when setup is spread across that period. This calculation says nothing about whether the duties are equivalent or which provider will perform better.
Now imagine the first offer excludes a required connection upgrade and the second has not confirmed the overnight delivery route. Keep both uncertainties visible. Do not assign a guessed value to the upgrade or assume the route is included. Request a revised quote or condition the decision on acceptance. If the term changes, repeat the calculation using the actual period and check whether early termination changes the payable amounts.
Make the call
Which figure belongs in the comparison?
| Situation | Decision to make | What to ask for |
|---|---|---|
| Setup is paid immediately | Cash due now versus a normalized monthly comparison | Both totals shown separately |
| Extra events are chargeable | What counts as a billable event | Duplicate rules and an illustrative busy-month bill |
| One bid includes attendance | Whether the other needs a separate response contract | The same response duties priced on both sides |
Before you move on
- Choose a common scope and term.
- Request all excluded charges and activity band rules.
- Resolve blank cells before choosing a supplier.
A worksheet you can actually use
Start with the blank sheet. Add one row per item, assign an owner and mark anything unresolved as pending. The completed example shows the level of detail to aim for.
Keep completed security plans private. Use aliases; keep passwords, access codes, personal contacts and footage links in your approved systems.
How to fill the worksheet
- Provider
- Identify the quoted organization and the written proposal version so later clarifications can be traced to the right offer.
- Covered views
- List the same required views for comparison and show any bidder-specific acceptance conditions rather than assuming equivalence.
- Hours
- State the viewing or review periods, including the treatment of holidays, changes and activities outside the quoted window.
- Recurring quote
- Preserve the currency, charging unit and recurring amount before calculating a normalized scenario total over the selected period.
- Setup quote
- Include stated one-time charges and distinguish installation, configuration or equipment that must be quoted separately.
- Excluded charges
- Keep required but unpriced items visible. Do not invent allowances merely to make a proposal appear complete.
- Term
- Record the comparison period and actual contractual commitment separately where they differ, including relevant notice conditions.
- Unresolved item
- State the missing answer, its decision consequence and who will obtain the clarification before selection or activation.
A worked example
Fictional comparison: proposal A includes gate speaker use; proposal B lists it as optional. The buyer adds the speaker charge to B before comparing recurring fees. No market price is inferred.
| Provider | Covered views | Hours | Recurring quote | Setup quote | Excluded charges | Term | Unresolved item |
|---|---|---|---|---|---|---|---|
| Example A | Gate and yard | Overnight | Enter quote | Enter quote | Local call-outs | Enter term | Export format |
Questions readers bring to this task
What else should you know?
Should we choose the lowest total?
Only after mandatory requirements are met and the scope is comparable. Record any accepted exception with its decision owner. If two proposals make different operating assumptions, resolve them before ranking the price; a spreadsheet cannot decide whether a missing duty is acceptable.
Link to this answer ↗Which currency should the comparison use?
Use one comparison currency and record the date and rate if a conversion is necessary. Retain the original quoted currency and identify taxes or transfer costs separately. Do not mix a converted monthly charge with an unconverted setup amount or present a fluctuating conversion as a fixed contractual price.
Link to this answer ↗Should I choose the lowest monthly fee?
Only after confirming that the essential duties, implementation costs and contract terms meet the requirement. A smaller monthly charge may be suitable for a narrower task. It may also leave required work outside scope. The worksheet helps identify the difference; it cannot decide your priorities for you.
Link to this answer ↗What if a provider quotes only after a survey?
Record the assessment as a pending dependency, supply the same site information to each provider and compare written scope assumptions while waiting. A provisional estimate is useful for planning when labeled correctly. It should not be treated as the final amount or used to claim a provider is definitively cheaper.
