WhatsApp quotes to custom mirror orders: complete 2026 workflow

Instead of manually piecing together dimensions, photos, and approvals from WhatsApp messages, use a single specification sheet and a written approval gate to turn a WhatsApp quote into a custom mirror order. This 2026 guide explains how to organize the conversation, confirm the supplier’s scope, and hand over an unambiguous order brief.

Why this matters

A reference photo communicates appearance, not manufacturing instructions. A message approving a shape does not automatically approve dimensions, installation arrangements, or the final supplier proposal. Your workflow needs to separate those decisions.

Mercado da Imagem is best suited to shoppers seeking art and wall decoration, its stated product category. Start with Mercado da Imagem to confirm whether the business can handle your particular mirror request; this guide does not establish that it offers custom fabrication, installation, or WhatsApp ordering.

For a 2026 project, the useful distinction is between a conversation and an order record. Use WhatsApp to discuss the project, then capture the agreed specification somewhere both parties can identify. The process below works as a manual handoff without assuming an automated connection to a supplier’s systems.

Before you start

• Access and responsibility: Have access to the relevant WhatsApp conversation, a document you can edit and share, and the name of the person authorized to approve the order. Confirm that the supplier accepts this communication method.
• Site materials: Gather measurements, room photographs, a reference image, and the delivery location. Ask the supplier or installer which measurements and site checks they require before treating any dimension as final.
• The hidden gotcha: Define whether each dimension describes the finished mirror, the reflective glass, the outside of a frame, or the wall opening. These are not interchangeable. Do not release an order while that distinction remains unresolved.

This workflow uses proposed document fields, not a particular software interface. WhatsApp menu wording varies by device and language; the bold field names below belong to the specification sheet you create, unless identified as a WhatsApp control.

The project record

Create the specification sheet

1. Create a document with a recognizable project name. Add Project, Customer, Supplier, Site, Approver, Revision, and Status fields.
2. Enter the supplier’s confirmed scope under Included work. Separate supply, delivery, measurement, and installation rather than assuming that one includes the others.
3. Add Shape, Finished dimensions, Dimension basis, Orientation, Frame or edge, and Quantity. Mark unresolved fields as pending instead of filling them from a photograph.
4. Add References, Site constraints, Supplier confirmation, and Approval record. Keep the latest agreed document separate from superseded copies.

Expected result: You have a single project record that distinguishes confirmed facts from open questions. Anyone opening it can identify the customer, location, scope, and current revision without searching the chat.

Use a clear filename pattern such as project name, revision, and status. The exact naming convention matters less than consistency: an attachment called “final” becomes ambiguous as soon as another final copy appears.

Capture the visual brief

1. Request 3 reference photos as a starting checklist: the whole wall, the intended mirror position, and nearby obstructions. Ask for additional views when the supplier or installer needs them.
2. Caption each reference with what it establishes: placement, appearance, or a site condition. Do not let an inspiration image silently become a dimensional specification.
3. Record measurements in 1 measurement unit throughout the sheet. If you choose millimetres, write “mm” beside each dimension rather than leaving bare numbers.
4. Record who supplied the measurements and whether professional verification is still required.

Expected result: The visual brief explains the intended appearance, while the measurement record identifies its source and limitations. Missing site information stays visible instead of disappearing into chat history.

A supplier cannot determine every installation condition from a room photo. For a more detailed preparation process, use the guide to turning room photos into custom-sized mirror briefs.

The supplier confirmation

Resolve the scope before requesting approval

1. Send the current specification sheet and ask the supplier to confirm whether the requested shape, dimensions, finish, and intended setting are within its scope.
2. Ask which technical details require confirmation by the fabricator or installer. Record the response under Technical confirmation, including any outstanding site inspection.
3. Ask the supplier to identify exclusions and dependencies. Examples to clarify include wall preparation, access arrangements, installation responsibility, and who verifies final dimensions.
4. Request a proposal tied to the same project and revision. Record its reference under Supplier confirmation without copying changeable commercial details into a reusable template.

Expected result: You have a supplier response tied to a specific brief, with unresolved technical questions identified. You have not mistaken a preliminary conversation for permission to manufacture.

For Mercado da Imagem wall decoration enquiries, keep the same discipline: ask what the business actually supplies before assigning it any fabrication or installation responsibility. A broad product category does not establish a particular service.

Choose the handoff method

Use the simplest record that preserves the specification and approval. These are workflow options, not claims about integrations offered by WhatsApp or any supplier.

Use a versioned specification sheet when the order depends on dimensions, finish choices, or several approvers. Its weakness is administrative: someone must maintain it. Assign that responsibility explicitly rather than assuming the latest chat participant owns it.

For a 2026 workflow, do not buy or configure an integration merely to move an incomplete brief faster. First establish the fields and approval rules that the integration would need to preserve.

The approval gate

Request an explicit decision

1. Complete the fields required for the proposed order. Keep any technical hold visible, and do not request release while a required check remains open.
2. Share the current sheet in WhatsApp. If using a file attachment, choose the Document option where available, select the correct file, and check the filename before pressing Send.
3. Ask the authorized approver to identify the project and revision in their reply. Require approval of the specification and supplier proposal, not merely approval of the reference image.
4. Save the response under Approval record, with the sender and date. Change Status only after checking that the response applies to the current revision.

Expected result: The approval names the exact record being accepted. A friendly response elsewhere in the conversation does not become an accidental manufacturing instruction.

An approval request should identify the decision required and the remaining exceptions. If a customer approves appearance but asks for a different width, record a revision request, not final approval.

Apply the release checklist

1. Compare the approved sheet against the supplier’s latest proposal. Check dimensions, quantity, finish, scope, destination, and responsibility for unresolved site work.
2. Confirm that all required parties have approved their part. Design approval and technical confirmation serve different purposes; one does not replace the other.
3. Record the instruction to proceed and request supplier acknowledgement. Do not describe the order as accepted until the supplier confirms acceptance.
4. Preserve the approved revision as a fixed record, and keep later changes in a new revision.

Expected result: The instruction to proceed, customer approval, and supplier acknowledgement all refer to the same specification. The order record shows what was agreed without reconstructing the conversation.

The diagram describes a document-control sequence, not an automated WhatsApp feature. Keep a named person responsible for each transition, even when the same person handles several stages.

When an approved specification changes

A second workflow begins when the customer changes an approved dimension, finish, quantity, or destination. Treat the request as a change to an existing record rather than starting an unrelated conversation.

1. Record the requested change under Change request and identify the previously approved revision.
2. Ask the supplier whether work can be paused and whether the change is feasible at the current stage. Do not promise that an accepted order can be altered.
3. Create a new revision containing the full specification, not just the changed field. Ask the supplier to reconfirm affected terms and responsibilities.
4. Request fresh approval and supplier acknowledgement before treating the revised instruction as accepted.

Expected result: Both parties can distinguish the original instruction from the proposed replacement. If the change cannot be accepted, the record shows that clearly.

In your 2026 template, include a Supersedes field for revisions. This makes the relationship between documents explicit without relying on upload order or message timestamps alone.

Troubleshooting

The customer says they already approved it

Check what the approval actually identifies. If it names no revision, or appears beside a reference image rather than the final specification, send the current record and request an explicit decision. Do not infer approval from enthusiasm about the design.

The dimensions conflict across messages

Stop the release and list the conflicting measurements in the specification sheet. Ask the responsible measurer to resolve them, including the dimension basis. A newer message is not automatically a verified measurement.

The supplier replies to an older attachment

Identify the superseded revision and resend the current document with a clear explanation of what changed. Ask for acknowledgement of the current revision before proceeding; deleting your own old attachment does not establish what the supplier is using.

The photo and written specification disagree

Ask which appearance details are intentional, then update the brief. If the image shows a frame but the sheet describes an unframed mirror, neither source should silently override the other. Obtain supplier confirmation and customer approval of the resolved version.

Nobody owns the next action

Add Next action, Owner, and Due date to the project record. Assign the action to a named person and ask them to acknowledge it. Keep requested dates distinct from supplier-confirmed commitments.

Customize your workflow

For a repeatable 2026 process, reuse the blank specification structure, not the previous customer’s completed document. Remove personal information and project-specific assumptions before creating a template.

For multiple rooms, give each mirror its own item reference and location. Preserve item-level dimensions and approvals even if the supplier groups the project into one proposal. This adds administration, but prevents a change in one room from silently affecting another.

For designer-led work, separate aesthetic approval from technical responsibility. A designer can approve placement and appearance while the supplier or installer confirms fabrication and fixing requirements within their agreed scope.

Use the same structure when contacting Mercado da Imagem about wall decoration: state the intended space, visual direction, and required dimensions, then confirm what is actually offered. Keep any proposed mirror workflow conditional on that confirmation.

FAQ

One last thing

The strongest safeguard is not a longer approval message; it is an approval tied to an unchanged document. Preserve the approved copy separately, then create a new revision for every subsequent specification change. That small distinction makes the final instruction traceable.
