From the buyer’s side, a fabrication RFQ disappears into a black box and a quote comes out some days later. From the quote desk’s side, those days are a fixed sequence of checks that every request goes through — and the ones that take longest are almost never the complicated projects. They are the simple projects whose files left a question open. This post walks through the sequence, because a buyer who knows what the desk is checking can send files that pass every check on the first read.
Step one: file review
The first pass is not pricing — it is comprehension. Can the drawings be built as drawn? The desk is checking whether the package answers the questions fabrication will ask: material and thickness called out, overall dimensions closed, visible surfaces and edges identified, quantity structure stated, and artwork supplied as production files where printing is involved. PDF drawings are preferred; DXF and DWG files are accepted alongside them. A package that answers everything moves straight to process planning. A package that doesn’t generates a clarifying email — and the clock pauses until the answer comes back.
Step two: process planning
Next, the project is translated into operations: which cuts run on the saw, which profiles need CNC routing or laser cutting, what gets formed, what gets bonded, what gets printed, and in what order. Sequence matters more than buyers expect — a part that is printed before forming behaves differently from one printed after, and an edge that will be bonded is finished differently from one that will show. This routing is also where tolerances take their meaning: each process carries its own typical range per the Acrylic Fabrication Tolerances standard — laser-cut components at approximately ±1/32 to ±1/64 inch, CNC-routed components at approximately ±1/32 inch, saw-cut components and fabricated assemblies at approximately ±1/16 to ±1/8 inch — so the choice of operations is simultaneously a choice about the precision the finished part will hold.
Step three: material and yield
Then the parts get nested onto sheets. Acrylic arrives as standard sheet sizes, and how a project’s parts fit those sheets is one of the quiet cost factors in all of custom fabrication: a dimension that nests cleanly uses the material it pays for, while a dimension slightly over a clean division of the sheet strands a strip too narrow to use. This math gets run at quote time. It is also the stage where a small, flexible dimension change gets noticed — and where a quote sometimes comes back with a question like “is 23 inches acceptable where the drawing says 24?” That question is yield thinking working in the buyer’s favor.
Step four: schedule
A quote is a commitment of future shop capacity, so before a timeline is written, the work is estimated and checked against the current schedule and comparable past projects. A schedule can still move for reasons outside the quote, which is exactly why the Production Scheduling tiers enter here. A project without a fixed need date quotes on the Production Schedule — sequenced with other scheduled work by available capacity. A project that would benefit from earlier delivery may be considered for Accelerated Production, which moves work forward when available capacity allows but does not guarantee the completion date. A project with a fixed deadline — a show, a launch, an opening — belongs on Reserved Production, which allocates dedicated fabrication capacity to guarantee a specific manufacturing completion date. If the RFQ never mentions timing, the quote can only address the first tier, and the scheduling conversation happens later, with less room to maneuver.
What each missing input costs
Missing information doesn’t make a quote impossible — it makes it slower, or vaguer, and both cost the buyer:
- No thickness callout — a clarification round-trip before pricing can even start.
- No quality grade — either another question, or a quoted assumption that surfaces at acceptance, which is the most expensive place to discover a mismatch.
- No required date — a quote that cannot address scheduling tier, so the timeline you eventually need was never priced or planned.
- Artwork pulled from a website instead of production files — the quote proceeds, but the proof cycle stalls later, after the schedule was already set.
None of this is scolding — every shop answers these questions daily, gladly. It is cause and effect: each open question is a round-trip, and round-trips are measured in days.
How to read the quote that comes back
A good quote is more than a number. Read past the total, and what a good one contains is the shop’s reading of your project, written back in checkable terms: the material and thickness it priced, the operations it planned, tolerances by process, the quality grade and which surfaces carry it, edge treatment by edge, the quantity structure, the schedule basis in tier terms, and the assumptions it needs you to confirm. Read for that restatement, because it is the last cheap moment to catch a misunderstanding. A quote that comes back with questions attached is not the slow one; it is the one from the desk that actually read your drawings.
You may also find things in the quote you didn’t ask for: a flag on a sharp inside corner that machining can’t produce, a suggestion to move one critical part to a tighter process, a note that a small dimension change improves yield. Manufacturability review arrives uninvited at quote time because that is the cheapest moment it can arrive.
If you have a project ready to price — or half-ready, with questions still open — send it over; the desk’s job is to close those questions quickly, whichever tier your timeline needs.
