Why Quotes for the Same Project Differ by 10x — and How to Compare Them

Send the same requirements to five vendors and the quotes come back ranging from NT$200,000 to NT$2,000,000 (≈US$6,400 to US$64,000). Nobody is necessarily ripping you off — each vendor is simply looking at a completely different project. This article shows you how to read a quote for where the differences hide, and whose professionalism deserves your trust.

Five Sources of a 10x Spread

1. Different readings of scope

You write "member features." Vendor A reads that as sign-up and login. Vendor B reads it as sign-up and login plus tiers, points, birthday rewards, and gamified missions. Same two words, five times the work. The number-one source of quote variance is always vague requirements — and that's not the vendors' fault; it's homework the requirements document didn't finish. On writing requirements, we have a separate RFP writing guide.

2. Whether the invisible work is priced in

Testing, security, performance, SEO, accessibility, documentation. A cheap quote usually isn't cutting corners deliberately — these items simply aren't in that vendor's vocabulary. You find out after launch: the site breaks on mobile, Google can't find it, and it falls over under load.

3. Who actually does the work

A senior engineer costs three times the hourly rate of a freelance beginner — but the gap in output quality and rework rate is even bigger. A cheap hourly rate often gets made back with double the hours, spent where you can't see them.

4. Maintenance and warranty scope

Some quotes include a year of warranty and basic maintenance; others start billing per incident the day after acceptance. This is the item most easily overlooked when comparing prices — and it's the bulk of long-term cost.

5. Company cost structure

A company with an office, a full-time team, and proper tax invoices inherently costs more than a solo freelancer. That doesn't make freelancers bad — but be clear-eyed: the price of cheap may be "will this person still be findable next year?"

The right way to compare quotes isn't finding the lowest price — it's normalizing every quote to the same scope first, then comparing.

Reading Professionalism From the Quote Itself

• A vendor who dares to write "not included" is more credible than one who only writes "included." Scope awareness is the first signal of professionalism.
• A vendor who asks about your business goals is more credible than one who quotes immediately. A price given without questions is a template price.
• If a quote is far below market, ask them to explain why it's cheap. If the answer is "we're very efficient," follow up with how they handle testing and documentation.
• Beware the single lump-sum price with no line items. A quote that can't be broken down usually means the vendor never actually calculated it.
