Purchasing premium natural stone is a significant investment, whether you are fitting out a family kitchen, constructing a luxury residence, renovating a hotel, or developing a commercial building. While buyers often focus on selecting the right marble, granite, quartzite, or engineered quartz, understanding the purchasing process is equally important. Knowing how quotations, deposits, VAT, payment methods, and invoicing work helps prevent misunderstandings and ensures the project progresses smoothly.
When buying natural stone in Kenya, every order is usually customised to the client’s specific requirements. Unlike off-the-shelf building materials, natural stone is cut, fabricated, and finished after measurements have been confirmed. Once fabrication begins, the stone cannot simply be returned to stock because it has been tailored for a particular project.
Recommended Stone Solutions
For this reason, reputable stone suppliers normally require formal quotations, approved drawings, deposit payments, and written confirmation before production starts. This process protects both the customer and the supplier while ensuring that the correct material, dimensions, and finishes are produced.
Understanding the purchasing process also helps buyers compare quotations more accurately. Two suppliers may offer similar-looking prices but include different payment terms, delivery arrangements, installation services, or tax treatments. Looking beyond the total price provides a much clearer picture of the overall value.
At Maruti Mining Limited, we believe that transparent quotations, clear payment terms, and professional documentation are essential parts of delivering premium natural stone projects. Our team works closely with homeowners, architects, contractors, interior designers, and developers to ensure every stage of the purchasing process is clearly explained.

Why a Formal Quotation Matters
The first step in buying natural stone in Kenya should always be obtaining a detailed written quotation.
A professional quotation should clearly describe:
- Material type
- Stone variety
- Slab thickness
- Surface finish
- Quantity
- Fabrication scope
- Installation scope
- Delivery arrangements
- Applicable taxes
This provides a reliable basis for comparing suppliers.
Understanding Deposit Payments
Most natural stone projects require an initial deposit before fabrication begins.
Deposits are commonly used to:
- Reserve selected slabs
- Purchase raw materials
- Schedule production
- Allocate fabrication time
Because each project is custom-made, fabrication generally starts only after the quotation has been approved and the agreed deposit has been received.
Why Deposits Are Important
Natural stone cannot usually be treated as a standard stock item once it has been fabricated.
A deposit helps cover:
- Material reservation
- CNC machining
- Edge profiling
- Custom cut-outs
- Labour allocation
This allows production to proceed with confidence that the project has been authorised.
Mobile Payments
Many suppliers now accept convenient electronic payment methods.
Common payment options may include:
- Mobile money services
- Bank transfers
- Corporate payments
- Electronic funds transfer (EFT)
The available methods vary by supplier, so it is advisable to confirm accepted payment options before placing an order.
VAT and Tax Considerations
When comparing quotations, it is important to establish whether VAT is included.
A quotation should clearly indicate:
- Material cost
- Fabrication cost
- Installation cost
- VAT treatment
- Total payable amount
Understanding the tax treatment helps prevent confusion when budgeting for the project.
Professional Invoicing
Following quotation approval, reputable suppliers issue formal invoices.
A professional invoice should normally include:
- Supplier details
- Customer details
- Invoice number
- Description of goods and services
- Payment terms
- Tax information
- Total amount due
Maintaining accurate documentation benefits both residential and commercial buyers.
Payment Schedules
Large projects may use staged payment arrangements.
Typical project milestones include:
- Deposit
- Fabrication completion
- Delivery
- Installation completion
The exact schedule depends on the project scope and supplier policies.
Confirming Your Order
Before production begins, buyers should verify:
- Stone selection
- Colour
- Thickness
- Finish
- Edge profile
- Drawings
- Measurements
- Delivery address
Careful review at this stage reduces the risk of costly changes after fabrication has started.

Understanding Lead Times
When buying natural stone in Kenya, production does not usually begin immediately after requesting a quotation. Each project follows a structured process to ensure the finished installation matches the approved design.
Typical project stages include:
- Quotation approval
- Deposit payment
- Material reservation
- Digital site measurement
- Final templating
- CNC fabrication
- Quality inspection
- Delivery
- Installation
Lead times vary depending on material availability, fabrication complexity, and project size.
Why Accurate Measurements Matter
Natural stone is fabricated specifically for each project.
Before cutting begins, professional suppliers normally confirm:
- Cabinet installation
- Finished wall positions
- Appliance locations
- Sink specifications
- Tap locations
- Site dimensions
Accurate measurements help minimise installation issues and reduce material waste.
Reviewing the Quotation Carefully
A quotation should explain exactly what is included.
Before approving the order, check that it specifies:
- Stone type and colour
- Slab thickness
- Surface finish
- Edge profile
- Number of cut-outs
- Splashbacks (if included)
- Delivery
- Installation
- VAT
- Warranty (where applicable)
An itemised quotation makes it much easier to compare competing suppliers.
Delivery Arrangements
Natural stone requires specialist transportation because slabs are heavy and fragile.
Delivery planning may include:
- Vehicle access
- Lifting equipment
- Safe unloading
- Storage before installation
- Delivery scheduling
Projects in apartments, high-rise buildings, or restricted-access sites should discuss logistics well before the installation date.
Inspecting the Stone Before Fabrication
Whenever possible, buyers should view the actual slab before fabrication begins.
This allows confirmation of:
- Colour consistency
- Natural veining
- Pattern movement
- Surface finish
- Overall appearance
Viewing the full slab helps avoid surprises because small samples rarely represent the complete stone.
Understanding Variations in Natural Stone
Every slab of natural stone is unique.
It is normal to see variations in:
- Veining
- Colour
- Crystal formation
- Mineral deposits
- Fossils (in some stones)
These natural characteristics are part of the appeal of genuine marble, granite, quartzite, travertine, and limestone.
Questions to Ask Before Paying
Before making a payment, consider asking:
- Is the selected slab currently in stock?
- Has the quotation included all fabrication costs?
- Are delivery and installation included?
- Is VAT included in the total?
- What are the expected lead times?
- Can the actual slab be viewed before fabrication?
- What happens if additional material is required?
Clear communication at this stage helps avoid delays and unexpected costs.
Common Buying Mistakes
Choosing a Supplier Based Only on Price
The lowest quotation may not include:
- Digital templating
- Professional fabrication
- Installation
- Delivery
- Quality inspection
Always compare complete project costs.
Approving Drawings Without Checking Details
Before fabrication starts, carefully review:
- Measurements
- Edge profiles
- Cut-outs
- Splashbacks
- Layout
Correcting mistakes before production is far easier than making changes afterwards.
Delaying Material Selection
Premium stone varieties can sell quickly.
Selecting and reserving slabs early improves the likelihood of securing matching material from the same production batch.
Why Documentation Matters
Keeping copies of all project documents provides clarity throughout the installation.
Important documents include:
- Formal quotation
- Approved drawings
- Deposit receipt
- Tax invoice
- Delivery confirmation
- Final invoice
Good documentation protects both the customer and the supplier while making future maintenance or additional orders easier.
