Furniture Lead Time Planning: When to Order for Each Stage
· 9 min read
Furniture lead time planning means working backwards from the renovation stage at which each item must be on site. Take that date and subtract the buffer, transit, production, payment and approval time. The result is the latest date you can place the order. Items with long production or with dimensions that affect the construction work have to be ordered while the renovation is still at an early stage.
Start from the renovation stage, not the purchase list
A purchase list sorted by room or by supplier tells you what to buy, but not when. Sort it by the stage at which each item is needed. Some items must be known before the walls are closed. Others can arrive on the last week. The sequence below is typical, so adjust it to your project and contractor.
| Item group | Needed by | Why this stage |
|---|---|---|
| Plumbing fixtures, built-in appliances | Before rough-in work | Dimensions and connection points define where pipes, sockets and cables go |
| Lighting and electrical fittings | Before electrical first fix and ceiling closing | Fitting type decides the cut-outs, power points and driver locations |
| Windows and exterior doors | Before finishing starts | Long production, and the measurement needs finished openings |
| Tiles, flooring, wall finishes | Before the matching finishing phase | The installer needs the material on site, often a few days early to acclimatise |
| Interior doors, wall panels, built-in furniture | Measurement after wet finishing; delivery after painting | Made to measure, so production cannot start until the site is ready |
| Loose furniture, upholstery | Final stage, after painting and cleaning | Easily damaged, and nobody wants to store it on a building site |
| Decor, textiles, accessories | Last week | Low risk and short lead time |
Next to every item, write down the construction phase that depends on it. That phase date becomes the target date for the calculation.
Break lead time into parts
A supplier who says "8 weeks" usually means production only. The real lead time is longer, and the extra parts are where most delays come from. List each part separately so you can see which one you can shorten.
| Part | What it covers | Where to get the number |
|---|---|---|
| Client approval | Time for the client to choose the finish and confirm the price | Your own experience with this client |
| Invoice and advance payment | Requesting the invoice, client payment, supplier payment | Supplier terms, your payment chain |
| Production or picking from stock | Manufacturing, finishing, quality check | Supplier quote, in writing |
| Shipping and customs | Transport to your country or city, border procedures | Supplier or forwarder |
| Delivery to site or storage | Last mile, lift, access hours | Contractor, building rules |
| Acceptance and claims | Checking the delivery, photos, replacing damaged parts | Your past projects |
| Buffer | Reserve for rescheduling by the supplier | Your own judgement, see below |
Choose the buffer by risk
Do not use one flat buffer for everything. A stock item from a local warehouse needs a small reserve. A custom piece from a workshop abroad needs a large one. A simple rule: the longer the chain and the more steps are outside your control, the larger the buffer. Keep a record of how often each supplier moved the date on previous projects and use it as the base for the next buffer.
Calculate the latest order date
- Set the target: the date the item must be on site, which is the start of the dependent construction phase or a few days before it.
- Collect each lead time part from the table above. Ask the supplier to confirm production time in writing and to say whether it counts working or calendar days.
- Convert everything to the same unit. Working days are easier to plan with, but supplier quotes are often in weeks, so convert them before adding.
- Add the parts and subtract the total from the target date, skipping weekends and public holidays.
- Mark two dates: the date to send the item for client approval, and the date to place the order. These are different dates, and the first one is earlier.
- Compare the result with the project calendar. If the order date has already passed, you have three options: choose a faster item, ask for an in-stock alternative, or move the construction phase.
Worked example
The example below uses invented numbers for a custom upholstered sofa that must be on site at the start of the final stage (day 0). All values are working days.
| Part | Working days | Cumulative, counted back from day 0 |
|---|---|---|
| Buffer | 10 | 10 |
| Delivery to site | 8 | 18 |
| Production | 35 | 53 |
| Invoice and advance payment | 3 | 56 |
| Client approval | 5 | 61 |
In this example the sofa goes to the client for approval 61 working days before the target, and production must start 53 days before it. That is about twelve working weeks, so the sofa is a rough-in-stage decision even though it arrives at the very end. The same method applied to a stock side table might give 12 days in total.
Handle items that depend on site measurements
Built-in furniture, wall panels, windows and interior doors are the hardest group. Production starts only after measurement, and measurement can happen only after the previous construction phase is finished. This creates a chain, and a delay in any link moves everything after it.
- Find the phase after which the measurement is possible, for example plastering for panels or finished openings for windows.
- Add the planned measurement date to the chain, plus the time needed to prepare drawings and get approval.
- Calculate production and delivery from the measurement date, not from the order date.
- Link the phases so that the measurement moves automatically when the previous phase moves.
- Give these items the largest buffer, because every phase delay passes directly into their delivery date.
Where possible, order the long-lead part first. For example, request the window quote and confirm production time while the contractor is still working on the walls, so you only wait for the measurement itself.
Keep the plan alive during the project
A lead time plan made on day one is wrong by week four. Review it on a fixed rhythm, for example once a week, and after every change in the construction schedule.
- Every item has a target date, a latest order date and an owner.
- Each supplier date is confirmed in writing, with a note on working or calendar days.
- Items waiting for client approval are highlighted, with a date by which the answer is needed.
- Measurement-dependent items show the phase they wait for.
- Any delivery date that moved is recorded with the reason, so you can see which suppliers are unreliable.
- Items with an overdue planned delivery date have a follow-up task, not just a memory.
- Storage is arranged for early deliveries, with someone responsible for checking them on arrival.
- The contractor knows the delivery windows and the access conditions.
How to do it in ArchiBoard
- Open the project and go to Timeline, then click Add Phase for each construction phase, such as "Electrical" or "Finishing".
- Enter the phase dates from the keyboard or drag the bar by its edge. Duration is counted in working days.
- Link phases with an arrow if one cannot start before the other, and set an offset in days if needed. When a phase moves, dependent phases shift automatically.
- Items from the estimate are placed into phases by category automatically. To change this, drag the item to another phase or click Move to phase….
- For each item, check the order, waiting and delivery segments on the timeline. Segments marked with 🔒 are calculated from the estimate, so change them in the item, not on the timeline. The delivery time can be filled in by Auto-fill from the product link or set in the web clipper in business days.
- Open the Upcoming purchases block to see what must be ordered first, sorted by order deadline. In Estimates, the By order priority view shows the same logic as a list.
- For built-in furniture, windows, wall panels and interior doors, enter the planned and actual measurement dates. The item shows an "Awaiting measurement" badge until the measurement is done.
- When a supplier changes the date, open Vendor & payment → Dates: delivery and installation, enter the new planned date and choose a Reason for reschedule. The history stays in the item and in the Suppliers list.
- Use the Mode switch in the timeline: Board for tasks by status, Timeline for the Gantt chart.
The system also creates tasks automatically, for example "Request delivery date from {supplier}" for an ordered or paid item without a date, and an urgent "Request new delivery date" when the planned date has passed. More details are in the procurement timeline feature overview, the help chapter on tasks and the estimates chapter.
FAQ
How much buffer should I add to the furniture lead time?
There is no universal figure. Use a small buffer for stock items from a nearby warehouse and a larger one for custom pieces, imports and anything that depends on measurements. Base the number on how often each supplier has moved dates on your past projects, and increase it when the chain has more steps outside your control.
Should I order furniture before the renovation starts?
Order early only what has a long lead time or affects construction: windows, built-in furniture, lighting and plumbing fixtures. Loose furniture can wait until the order date from your calculation, as long as storage is not a problem. Ordering everything on day one ties up the client's money and creates storage and damage risks.
What if the supplier gives only a range, such as 6 to 10 weeks?
Plan with the upper value and ask for a written confirmation before the order. If the longer value does not fit your schedule, ask what influences the range, such as fabric availability or the workshop queue, and whether a deposit reserves a production slot. Otherwise treat the item as high risk and prepare an alternative.
How do I plan items that need measurements on site?
Put the measurement on the schedule as a separate step after the phase it depends on. Count production and delivery from the measurement date and link it to that phase, so that a delay is visible immediately. Use the largest buffer for these items, because every construction delay is passed on to their delivery.
What should I do when an item will arrive too early?
Check first whether the supplier can hold the goods in their warehouse. If not, arrange storage and name a person responsible for accepting the delivery and checking it for damage. Do not put finished furniture into a room where dusty work is still going on, because covering is rarely enough to protect it.
