Structuring client approvals for dual NYC and Hamptons properties

If you run an interior design studio in New York, managing a dual-property client can quietly drain your time and your margin. It is a common metropolitan pattern — the same client signs a contract for a complete refresh of their Upper East Side townhouse and a full build of their shingle-style retreat in Water Mill.

While it is one client and one relationship, treating these two properties as a single project in your system creates operational friction. Most studios already organize projects across pins, spreadsheets, and Gmail folders long before a dedicated system enters the picture. However, when you mix Manhattan specifications with East End purchase orders, small details get lost. A fabric meant for the beach house gets ordered for the city library — or a delivery truck arrives at a townhouse with a crate built for a Hamptons driveway.

To protect your margins and your sanity, you must separate these properties operationally from day one.

Structure your approvals by location, not just by room

When you present a massive, combined PDF deck or a single digital spreadsheet to a client, you invite decision fatigue. A client sitting in their Manhattan office does not want to review a custom velvet sofa for their living room right next to outdoor teak chaises for the pool deck in Bridgehampton. The aesthetic languages are different — the timelines and mental compartments are different, too.

Instead of grouping your approvals strictly by item type or room across the entire engagement, group them into distinct property scopes.

Presenting separate, bite-sized approval packages allows the client to sign off on the city residence and the beach house in separate, clean steps. This keeps their focus sharp. They can approve the city dining room selections on Monday — then they can review the Hamptons guest suites on Thursday without feeling overwhelmed by a hundred unrelated line items.

The math of dual-property procurement: sales tax and landed costs

The financial realities of New York City and Suffolk County require precise tracking. If you apply the wrong tax rate or delivery address during the approval stage, your accounting cleanup later will be painful.

Consider a typical scenario with two high-end pieces:

• The Manhattan Dining Table: Sourced from a workshop in Brooklyn for the city townhouse.
  • Net wholesale cost: $12,000
  • Markup (35%): $4,200
  • Client subtotal: $16,200
  • NYC sales tax (8.875%): $1,437.75
  • Manhattan white-glove delivery: $800
  • Total client cost: $18,437.75
• The Hamptons Custom Sectional: Sourced from a vendor in North Carolina for the Water Mill living room.
  • Net wholesale cost: $15,000
  • Markup (35%): $5,250
  • Client subtotal: $20,250
  • Suffolk County sales tax (8.625%): $1,746.56
  • Freight and East End receiver delivery: $1,800
  • Total client cost: $23,796.56

If these items are grouped on the same client proposal, your team has to manually calculate two different tax rates based on the final delivery destinations. If your spreadsheet or software only allows one tax rate per project, you will likely default to the NYC rate. On a large project, that 0.25% variance adds up — and filing incorrect sales tax returns to the state creates unnecessary audit risks.

By assigning the correct tax rates, delivery addresses, and receiving warehouses at the product level during the initial design phase, your purchase orders and invoices will automatically generate with the correct financial data.

Sequencing the logistics: city tight spots vs. Hamptons seasonal windows

The physical constraints of a Manhattan delivery and a Hamptons install require entirely different operational timelines.

A Manhattan townhouse delivery is an exercise in precision. You need a Certificate of Insurance (COI) for the building, a reserved freight elevator, and a narrow parking window on a busy street. You are often limited to a strict 9:00 AM to 4:00 PM weekday schedule.

A Hamptons delivery has different hurdles. Route 27 traffic can delay trucks for hours during the summer season. Many local home associations ban construction and large deliveries between Memorial Day and Labor Day. Additionally, you must coordinate with local receivers who specialize in East End routes.

To manage this, structure your approvals so that long-lead items for both properties are approved and ordered early — but warehouse receiving and final delivery are phased separately.

For example, approve the custom upholstery for both homes in the autumn. This allows the items to arrive at your receiver during the winter. You can then schedule the Manhattan install for a quiet week in February — and hold the Hamptons items in storage until the local roads clear and the property is ready in early May.

How Alcove keeps your dual-property approvals organized

Instead of running two completely separate projects or risking a mixed-up spreadsheet, you can manage both properties under one client umbrella.

Alcove lets you organize a single client project into separate location scopes with dedicated client approval portals, keeping budgets, tax rates, and delivery addresses isolated.

Your client sees a clean, organized portal where they can approve the city townhouse items and the beach house items in their own dedicated tabs. Behind the scenes, your team can generate purchase orders with the correct sales tax rates and shipping addresses automatically, keeping your QuickBooks sync clean. So you can spend more time on design decisions and less on copying cells.

FAQs

Should I create two separate projects in my accounting software for a dual-property client?

Yes, it is highly recommended. Keeping the Manhattan and Hamptons properties as separate sub-projects or classes ensures your sales tax reporting, freight costs, and profitability metrics remain accurate for each location.

How do I handle receiving when items for both homes are arriving at the same time?

Work with a receiver that has locations or delivery routes serving both metro NYC and the East End. Ensure every purchase order explicitly states the final destination property so the warehouse can tag and stage the items in separate bays.

How do I present a unified budget to the client while keeping approvals separate?

Use a system that allows you to show an overarching project financial summary to the client for peace of mind, while still sending separate, bite-sized approval packages for the individual city and beach house scopes.
