Define the decision before asking for a signature

“Sample approved” is an incomplete instruction when several decisions sit behind one finish. A client may like the colour without accepting the price, while a fabricator may be waiting for permission to cut. Before the first sample meeting, ask the designer to explain the approval stages in the appointment: appearance selection, technical coordination, purchasing authority and acceptance of delivered or installed work.

Give each stage a recognisable outcome. A concept board can establish a direction; a labelled physical sample can confirm a particular product and finish; a mock-up can show an important junction. None should silently become authority for a different stage. The site’s interior designer process guide helps place these decisions within the broader design sequence. Use the appointment to specify which stages the designer actually provides and which remain with the client, supplier or contractor.

Split aesthetic choice from technical responsibility

The client should know what they are being asked to choose: colour, texture, visible pattern, sheen or an agreed combination. The designer should identify how that choice relates to adjacent finishes and the design intent. The supplier should identify the exact product and explain relevant product limitations. The installer should raise application and interface concerns within their scope before proceeding.

Agree these responsibilities expressly rather than assuming every designer appointment includes purchasing or site inspection. A client’s preference for a surface should not be recorded as the client verifying its installation method. Equally, a designer’s aesthetic recommendation should not be mistaken for release of an order when purchasing authority remains elsewhere. Put the decision-makers and any spending limits in the interior design brief, then carry them into the agreed appointment and project communications.

Use a sample that represents the product being ordered

Ask whether the sample is a colour chip, a piece of the specified product, a production sample or a representative example from another batch. That distinction changes what the client can reasonably judge. EGGER states in its customer advice services information that colour-matching finish selection requires the original sample. A digital reproduction can help shortlist options, but it is a weaker basis for agreeing the physical match.

For patterned materials, sample size also matters. A small piece may show the background colour while excluding the dominant pattern. Ask for the larger view needed to understand the intended application, and identify where a full-size mock-up or slab layout is worth the additional effort. Keep the evaluation proportionate: an inexpensive cupboard interior and a prominent bookmatched feature require different evidence. The approval record should say what the supplied sample demonstrates and what remains to be checked.

Record variation instead of promising an exact replica

Natural material variation needs a specific discussion. Cosentino’s Sensa slab quality-control document explains that slabs of the same named natural stone can vary in tone and show colour concentrations. It also distinguishes those characteristics from other nonconformities. That is evidence about the documented Sensa range, not a blanket rule that every difference in every stone product is acceptable.

Ask the supplier how variation will be represented for the material actually proposed. Options might include viewing the intended slabs, reviewing a range of representative pieces or agreeing a layout before fabrication. Record the chosen evidence and any identified feature the client wants positioned or avoided. A note saying “natural variation accepted” should not replace a description of the range reviewed. It also does not resolve wrong product identity, damaged material or work outside the agreed specification.

Make approval traceable to one instruction

A useful sample record identifies the room and surface, manufacturer, product reference, finish, sample identifier and relevant drawing revision. Add the date and conditions of viewing, the client decision and any stated limitations. Link the physical sample to the record with a label that survives handling. Retain a reference sample where practical, particularly when installation will occur after the client has left Cyprus.

Use clear statuses such as selected for appearance, awaiting information, approved for the stated order, or rejected with a reason. Explain them in the project procedure rather than relying on their wording alone. Separate an approval condition from a casual comment: “subject to seeing the actual slab” means the cutting release is still unresolved. Identify who checks that condition and who communicates the final instruction to the person placing the order. Copying everyone into an email does not establish that responsibility.

Follow the discrepancy before deciding who is at fault

When a finish looks wrong, begin with identity. Does the delivered product reference and finish match the approved instruction? If not, ask the purchasing contact and supplier to reconcile the documents before further use. If identity matches, compare the retained sample and supplied material under comparable conditions. Ask whether the concern is colour, pattern, sheen, damage or an installation detail; each points to different evidence.

If the concern is an interface or workmanship issue, send it to the designer and responsible installer with the relevant detail and location. If it concerns product variation, request the supplier’s applicable product information and the approval evidence. If the instruction itself is ambiguous, resolve that ambiguity before issuing another order. This is an escalation route, not a remote diagnosis or allocation of contractual liability. Preserve photographs and references, and agree whether the affected work should pause while the discrepancy is investigated.

A hypothetical joinery and stone approval

Imagine a client selecting pale joinery doors and a natural stone counter for an apartment. This is a hypothetical appointment example. The designer presents a labelled original door sample, a small stone piece and a rendering. The client likes the combination. The record approves the door appearance but states that stone selection remains subject to reviewing the intended slabs and layout. Purchasing release is a separate instruction.

A proposed replacement door finish later arrives because the selected finish is unavailable. Although its colour name sounds similar, the designer obtains a new physical sample and explains the programme implications before seeking a decision. Meanwhile, the fabricator is told that the stone cutting release remains pending. The process prevents one broad approval from being stretched across a substitution and an unresolved slab choice. It does not guarantee the final result; it makes the outstanding decisions visible before fabrication.

Agree substitutions and final comparison in the appointment

Ask how the appointment handles replacement products, repeated sample meetings and late client changes. Identify who obtains samples, who pays supplier charges if any, who tracks decision dates and what happens when a deadline is missed. Avoid inventing a universal number of included revisions. The agreed service should explain whether site attendance and comparison against the approved sample form part of the designer’s work.

At completion, compare the relevant installed areas with the agreed references and document specific exceptions. Keep product records and care information with the handover so future repairs do not depend on someone remembering a showroom name. When comparing designer appointments through interiordesigner.cy, describe the finishes that worry you, whether you can attend in person and whether purchasing is included. Seek a responsibility split that follows the actual work, from first selection through order release to any unresolved installation concern.

Frequently asked questions

Does approving a colour sample authorise the order?

Only where the agreed procedure makes that approval an order instruction. Record appearance selection and purchasing release separately when different people control them.

Can a rendering replace a physical finish sample?

A rendering can communicate design intent. For physical colour matching, obtain the relevant original product sample and record any remaining limits.

Should a client accept every difference in natural stone?

No. Compare the actual product documentation, variation discussed and approval evidence. Natural variation does not automatically explain wrong identity, damage or an installation discrepancy.

Who handles a proposed substitute?

Name the coordinator in the appointment. The supplier identifies the replacement, the designer explains design implications within scope, and the authorised client or purchasing contact releases the revised order.

Compare designer appointments and clarify sample selection, purchasing and inspection responsibilities.
