How to Read a Signage Quotation (Line by Line)
Short answer: A complete signage quotation names the sign's size and drawing reference, every material and its grade, the LED and driver specification, the fixing method, who does the electrical connection, whether the license and landlord approvals are included, access equipment, removal of any old sign, warranty terms, timeline, payment stages and exclusions. If a line is missing, assume it is not included.
Why a quote is worth reading closely
Most signage disputes start with something the quote did not say. The sign looks right, but the electrical point was "by client", the license was "to be advised", or the lift for installation was never priced. Reading the quote line by line takes ten minutes and is the cheapest way to avoid a surprise invoice.
It also makes quotes comparable. Two suppliers may quote $900 and $1,500 for the "same" lightbox; once you lay out what each line includes, the gap usually explains itself.
What each line should say
Quote line | What a good quote states | Why it matters |
Description and drawing | Sign type, overall size, quantity, reference to a drawing or mock-up | Ties the price to an agreed design |
Face material | Acrylic type (cast or extruded), thickness, colour, print or vinyl | Affects clarity, fading and resistance to cracking |
Body and returns | Aluminum, stainless steel grade (304 or 316), galvanised steel, finish | Decides rust resistance and look |
Illumination | LED brand or grade, quantity, colour temperature, lit or unlit | Brightness, evenness and lifespan |
Driver (power supply) | Brand, wattage, IP rating, location | The most common point of failure |
Fixing method | Bracket type, anchors, wall type, any frame or spacers | Safety and facade damage |
Electrical works | Who provides the power point and connects the sign | Often excluded and billed later |
Installation and access | Ladder, scissor lift or boom lift, day or night work | Lift hire is $300 to $800 a day |
Approvals and license | Landlord drawings, BCA license handling fee, BCA fee, PE if needed | License handling is $300 to $700 |
Removal | Dismantling and disposal of an old sign, wall making-good | Easy to forget on replacements |
Warranty | Period and coverage for structure, electrics and finish | Defines who pays when something fails |
Timeline | Lead time from approval and from deposit | Sets expectations for opening dates |
Payment terms | Deposit, progress payments, balance trigger | Protects both sides |
Validity and GST | How long the price holds; whether 9% GST is included | Avoids price changes and confusion |
Exclusions | Anything specifically not included | The most important line to read |
The lines that cause most surprises
Electrical works "by others"
An illuminated sign needs a power point close to it. If the quote says electrical works are by others, you will need to arrange and pay for that separately, through your landlord's or your own licensed electrical worker. Ask the sign maker to check the power point position during the site survey.
License "to be advised"
There are two different costs: the BCA license fee itself, which is paid yearly and starts at $20 for a small advertisement or $50 for a signboard of up to 15 m² (BCA), and the sign maker's fee for preparing drawings and submitting. Make sure the quote says which is included.
Access equipment
For anything above ladder height, a scissor lift or boom lift may be needed. Some malls and buildings also restrict installation to night hours, which can affect the price. Ask whether the quote assumes daytime work.
Professional Engineer certification
Large signs carried on an advertising structure, generally those over 10 m², need a Permit To Use from BCA, submitted by a Professional Engineer. A PE certificate typically adds $500 to $1,500. If your sign is near that size, ask.
A worked example
Here is how a vague line compares with a clear one for the same sign.
Vague | Clear |
Acrylic lightbox with LED, 2 m by 0.6 m | Single-sided lightbox, 2,000 mm by 600 mm by 120 mm deep, powder-coated aluminum frame (black), 5 mm cast acrylic face with digital print and UV laminate, LED modules [brand], 6,500 K, IP65 driver [brand] mounted behind access panel |
Installation included | Installation at 3.2 m height using ladders, daytime, wall type: concrete with tiles; fixing with stainless steel anchors |
License extra | BCA license handling included; BCA license fee payable by client annually |
The clear version tells you what you are buying and gives you something to hold the supplier to.
Questions to ask before you sign
What is not included?
Does the price assume a power point within reach of the sign?
What happens to the price if the landlord asks for changes?
Is the warranty in writing, and what voids it?
When will the shop drawing be ready for my landlord?
How long does fabrication take after approval?
Payment terms, validity and timelines
A complete quote also tells you how and when you pay, and when you get the sign:
Deposit and balance: a deposit on confirmation and the balance on completion is common; be wary of full payment before design approval.
Validity: how long the price holds, since material costs change.
Lead time: from approved design to installation, and whether it depends on approvals.
GST: whether prices include GST (9% in Singapore) if the supplier is registered.
Spotting variation risks
Some wording means the final bill could change. Look for:
Wording | What it means | What to ask |
"Subject to site survey" | The price may change after the survey | When will the survey happen, and what could change? |
"Provisional sum" | An allowance for work that can't be priced yet | How is the final amount calculated? |
"Excludes..." | Items you will pay for separately | Get those items quoted now |
"Electrical by others" | You must arrange the power connection | Who will do it, and at what cost? |
"License fees not included" | BCA fees are on top | Is handling included, and what are the fees? |
Frequently asked questions
Should a signage quotation include GST?
If the supplier is GST-registered, the quote should state whether prices include or exclude GST, currently 9%. Ask if it is unclear.
What does "supply and install" mean on a sign quote?
It means the supplier makes the sign and fixes it in place. It does not automatically include the electrical connection, license, lift hire or old sign removal, so check those lines separately.
Why is my lightbox quote much cheaper than another?
Usually because of materials (extruded instead of cast acrylic, unbranded LEDs, a driver without a waterproof rating) or scope (no license, no electrical works, no access equipment). Compare line by line.
Can I ask for a revised quote after the site survey?
Yes. A survey often changes the fixing method, access or electrical scope, and a fair supplier updates the quote to match.
What is a provisional sum on a signage quote?
An allowance for work whose cost can't be fixed yet, such as wall repairs found after the old sign comes off. The final amount is adjusted to the actual cost, so ask how it will be calculated.
Should a signage quote include GST?
If the supplier is GST-registered, the quote should say whether its prices include GST, which is 9% in Singapore.
