Make sure the quotes describe the same job
A quotation is useful only when you can tell what the provider will deliver for the stated price. Two totals may look comparable while one covers preparation, materials and cleanup and the other covers labour alone. Start by agreeing the job, then compare the money.
This guide applies to everyday services such as painting, repairs, cleaning, moving and installation. The details vary, but the method is consistent: describe the work, identify what is included, resolve uncertain costs and record the agreed terms before the job starts.
For specialist or safety-critical work, confirm appropriate competence and obtain technical advice where needed. A low price cannot establish whether the proposed method is suitable. The figures used below are invented examples, not current Sri Lankan service rates.
Send each provider a clear description
Give each provider the same information: location, quantities or measurements, condition, required result, access restrictions and preferred timing. Photographs can help, but say what they do not show. If a site visit is necessary to establish the scope, arrange it before treating the price as settled.
For example, a painting request could identify the rooms and surfaces, approximate area, existing flaking or damp, finish required and whether furniture must be moved. Ask the provider to confirm measurements and preparation after inspection. If the underlying problem is water entry, repainting alone may not address it.
For a move, specify pickup and delivery addresses, stairs or lifts, parking, packing responsibility and unusual items. For an appliance repair, provide the model, symptoms and what has already been tried. More accurate information reduces the chance that providers price different assumptions.
- Describe the result, quantities and surfaces or items involved.
- Disclose known defects and practical access constraints.
- State who supplies materials and who prepares the area.
- Ask whether inspection or call-out charges apply even if you do not proceed.
- Share material clarifications with every provider still being considered.
Ask whether the price is fixed, estimated or based on usage
Providers may use the words quote and estimate differently. Ask them to state the pricing basis and change conditions in writing rather than assuming the heading determines every obligation. For a significant engagement, have unclear terms reviewed before accepting.
If a repair cannot be priced until equipment is opened or a concealed area inspected, agree the diagnostic fee and a pause for approval. Record what happens if you decline further work, including safe reassembly, temporary protection or return of the item where applicable.
| Pricing approach | Question to resolve before agreeing |
|---|---|
| Fixed price for a defined scope | Which assumptions or approved changes can alter the amount? |
| Estimate before full inspection | What remains unknown, and when will the provider confirm a revised price? |
| Hourly or daily rate | How are hours recorded, what is the minimum charge and is travel included? |
| Rate per unit or measured area | Who confirms the quantity, and how will the final measurement be agreed? |
| Allowance for an undecided item | What amount is allowed and how will the actual selection change the total? |
Read the scope, materials and exclusions line by line
Descriptions such as premium materials or complete service are difficult to verify. Ask for a specification that matters to the job. If a brand or part is unavailable, agree that substitutions require approval and clarify any effect on price or warranty.
Mark an unpriced exclusion as unresolved, not zero. Ask whether you can supply an item yourself and how that changes installation responsibility, compatibility checks and follow-up. A cheaper material is only a saving if it still meets the required use.
| Item | What to compare |
|---|---|
| Labour and preparation | Inspection, protection, removal, preparation, installation and testing |
| Materials and parts | Type, specification, quantity, new or refurbished condition and substitutions |
| Access and equipment | Parking, scaffolding, lifting, special tools and transport |
| Finishing and cleanup | Making good, disposal, packing removal and the condition in which the area is left |
| Timing | Start window, expected duration, working hours and dependencies |
| Follow-up | Defect correction, workmanship terms, manufacturer cover and contact arrangements |
| Final amount | Applicable taxes, delivery, call-out charges and other mandatory costs |
A worked comparison: the lowest headline price can change
Imagine three quotes for the same room-painting job. After clarification, each provider confirms the same area, preparation, finish and required work. Provider A originally quoted labour only; Provider B quoted an inclusive total; Provider C excluded cleanup. The additions below are confirmed amounts, not guesses.
Assume all figures use the same tax treatment and that there are no other mandatory charges. Real quotes should state applicable taxes explicitly. This example isolates scope differences and does not assess workmanship or suitability.
| Comparable item | Quote A | Quote B | Quote C |
|---|---|---|---|
| Original quoted amount | LKR 45,000 | LKR 78,000 | LKR 72,000 |
| Required materials omitted from original amount | + LKR 25,000 | Included | Included |
| Required preparation omitted from original amount | + LKR 8,000 | Included | Included |
| Required cleanup omitted from original amount | + LKR 4,000 | Included | + LKR 5,000 |
| Total for the agreed common scope | LKR 82,000 | LKR 78,000 | LKR 77,000 |
Agree how hidden problems and extra work will be handled
A provider may discover damaged components, unsafe wiring or a surface that needs more preparation than was visible. Agree a process before work starts: explain the finding, show supporting evidence where practical, describe the proposed response and obtain approval for cost and time changes.
For example, if an additional repair is proposed, the change record should identify the work, its price, the new total and any completion delay. Keep the original scope and all approved changes together. A discussion onsite can be followed by a written confirmation that both parties acknowledge.
Keep your own contingency for uncertainty, but do not treat it as permission for the provider to spend without approval. Where urgent action may be needed to make the site safe, agree who can authorise it, a spending limit if appropriate and how you will be contacted. Do not ask anyone to continue unsafe work while waiting for a pricing decision.
Check deposits, validity and payment milestones
Confirm how long the quote remains valid and whether a proposed start date is reserved or only indicative. Ask what depends on materials, access, weather or earlier jobs. Record cancellation and rescheduling terms, including what happens to a deposit.
A deposit may fund booking or materials, but its purpose and treatment should be clear. Confirm the recipient, amount, receipt and whether it is credited towards the total. Use a traceable payment method and verify changed payment instructions through a known contact.
For larger jobs, consider payments linked to identifiable stages agreed in advance. Specify how completion will be checked and when the balance falls due. If an LKR 78,000 job includes an LKR 20,000 deposit credited to the price, the remaining amount is LKR 58,000 before any approved changes; the deposit is not an extra charge.
Compare the provider as well as the price
Check who will do the work, relevant experience, availability and examples of similar jobs. Ask a reference about the finished result, treatment of changes and whether the provider returned to address a problem. A clear quote is helpful, but it is not proof of competent work.
Ask what follow-up is offered, for how long, and what is excluded. Distinguish cover for a supplied part from correction of installation or workmanship. Confirm whether transport, call-out or labour charges apply when reporting a defect, and keep any written warranty or service terms.
If one price is much lower, ask which method, specification or assumption explains it. If one is much higher, ask what additional work or service it includes. Avoid assuming either cheap or expensive automatically means better value.
Keep the records you need at completion and afterwards
Review the result against the agreed scope with the provider. Check the relevant operation, finish, cleanup and included items, and note outstanding work. For specialist testing or certification, obtain appropriate professional evidence rather than relying only on how the work looks.
Request an itemised final account showing the original price, approved changes, payments already made and balance. Keep the quote, messages, photographs where appropriate, receipts, part details and follow-up terms together. Explain any discrepancy promptly and ask for a written response.
If a problem remains unresolved, document the issue, the remedy requested and the steps already taken. Sri Lanka's Consumer Affairs Authority publishes information on complaints involving goods and services. Check its current process, time limits and whether it can handle your matter promptly; specialist services or contractual disputes may need another route. Do not assume a particular remedy is guaranteed.
Your final quote-comparison checklist
Choose the quote that offers a credible method and a clear, manageable commitment for the work you need. If the total is still impossible to establish, narrow the first stage to a defined inspection or investigation before authorising the full job.
- Every provider has priced the same required result and quantities.
- The pricing basis, assumptions and validity period are clear.
- Materials, labour, preparation, access, cleanup and taxes are accounted for.
- Unpriced exclusions and possible additional charges have been resolved or clearly identified.
- Extra work requires an agreed approval process.
- Timing, deposit, cancellation and payment terms are recorded.
- The provider's capability and follow-up arrangements are suitable.
- The accepted version of the quote and later changes are saved together.
Frequently asked questions
Is a quote always a fixed price?
Do not rely on the heading alone. Ask the provider to state whether the amount is fixed for the described scope, estimated or based on time or quantity, and what can change it. Have unclear terms reviewed for a significant commitment.
How do I compare a labour-only quote with an inclusive quote?
List the materials and other work required for the same result, obtain confirmed prices for missing items and add them to the labour-only amount. Do not assume exclusions cost nothing. Ask for the accepted scope and revised total in writing.
Should I always ask for the cheapest materials?
Choose a specification suitable for the job and compare providers on that basis. Cheaper parts or materials may affect compatibility, expected use or follow-up. Agree substitutions before they are purchased or installed.
What if the provider cannot see the whole problem in advance?
Agree a defined inspection or diagnostic stage, its fee and what happens if you decline further work. Require a revised scope and price before additional work proceeds, with a separate plan for making any immediate hazard safe.
How much deposit is reasonable?
There is no universal amount for every service. Ask what the deposit funds, how it counts towards the price, the refund or cancellation conditions and what evidence you receive. Consider the size and risk of the commitment before paying.
Can the final invoice include extra work I did not approve?
Ask for the reason, supporting records and the agreed basis for each addition. Compare the invoice with the quote and change approvals and raise discrepancies promptly. Your position depends on the facts and terms; seek appropriate advice if agreement cannot be reached.
What records should I keep if the work is defective?
Keep the accepted quote, changes, messages, payment receipts, relevant photographs, warranty terms and a dated description of the problem. Contact the provider promptly and check any applicable complaint process and time limits rather than waiting indefinitely.
