Answer the BOM sent on WhatsApp with a quote the buyer can compare.
A founder building a smart meter sends a BOM, Gerbers and a pick-and-place file to five assemblers in one message. The first to reply with a clear per-board price, a note on the missing footprints and a date for the first article has the strongest claim on the lot. The others are still reading the zip file.
Scope, fee, reporting and term are agreed in writing after we have read your brief and spoken to you.

In one paragraph
A PCB assembly company mounts and solders components on printed circuit boards for other brands, from SMT and through-hole work to testing and box build. Marketing brings OEM and startup engineers to your line. Sales converts each BOM and Gerber pack into a turnkey or consigned quote. GullySales builds the capability pages and the BOM-to-order follow-up.
Assembly shops do the hard part well: component sourcing, reflow profiles, inspection. They describe it as "SMT and DIP assembly available". Buyers searching for a place to build fifty units, or for an NPI partner, cannot tell if the line suits them.

How buyers decide
How PCB assembly companies are chosen.
Early-stage buyers choose on responsiveness and on whether the shop will talk through design-for-manufacture issues before building. A founder with a first prototype wants someone who will say the footprint is wrong, not someone who builds it and sends a bill.
OEM purchase teams choose on component sourcing and quality systems. They ask who buys the parts, how counterfeit and shortage risk is handled, what inspection and testing exist, and whether the shop has built boards like theirs. Turnkey versus consigned parts changes both price and risk, and the buyer needs that explained plainly.
Longer programmes bring in a plant visit, a trial lot and a quality agreement. Once these are in place, the buyer has little reason to change shops until service slips.
The problem
What usually goes wrong for PCB assembly companies.
What owners tell us on the first call, in their words.
“The BOM comes in and the quote takes a week”
Half the parts need pricing from distributors, the quoting engineer is on the floor, and the buyer has moved on by Thursday.
“Founders think we only do large volume”
Your line takes small lots, but the website talks about capacity, so prototype and pilot work goes to a smaller shop.
“We win the first lot and lose the next one”
The buyer finds a cheaper shop when volume grows because nobody on our side checks in after the first delivery.
“Our component sourcing is a strength nobody knows about”
Buying parts from authorised channels protects the customer from counterfeits, but the page never says how it is done.
“Enquiries arrive as incomplete files”
No pick-and-place data, no polarity marks, no alternates listed, and the sales person spends days chasing the missing pieces.
“Customers audit us and the paperwork scatters”
Process records, ESD controls and calibration details are in different hands, and a visiting customer team sees the gaps.
What we do
What we do for PCB assembly companies.
Everything included for PCB assembly companies.
Capability page with the line described
Machines, placement range, component sizes, reflow, inspection and test steps, ESD controls and the kinds of boards built, written in plain terms for an engineer.
BOM intake and checking routine
A form and a WhatsApp route that collect BOM, Gerbers and placement data, with a short list of what is missing and a named person who replies.
Turnkey and consigned explained
A simple page that explains the two ways of working, who buys what, and how shortages are handled.
Quote tracker
Every BOM logged with the buyer, the lot size, the price and a follow-up date.
First lot to second lot routine
A plan to contact each customer after delivery, collect feedback on yield, and learn the next lot date.
Customer audit pack
Process records, calibration and training records in one maintained folder.
BOM-to-lot sheet
BOMs received, quotes, orders and repeats in one sheet, so each built lot traces back to the file that started it.
How the result is measured
- BOMs received from startups, OEMs and marketplaces
- BOMs that arrived complete against those that needed chasing
- Prototype lots that grew into production lots
- Second and third lots by customer
- Days from BOM receipt to the quote leaving
- Marketplace enquiries that became orders
Recorded as a baseline before work starts, so every later report has an honest comparison.

Not for
It is not the right fit if.
- You want a guaranteed Google ranking or a guaranteed number of leads. Nobody honest can promise either.
- You need enquiries by next week and have nobody to answer them.
- You want posts and reach reported, not enquiries and orders.
How it works
From your first message to the first report.
No open-ended retainer. Every step gives you something in writing.
First
Your brief
You tell us what you need in a few short steps: your business, what you want, where enquiries come from and how they are handled.
After the brief
A conversation and a written scope
We read it, then talk with whoever handles your enquiries. If you want our help, the scope, the fee and the reporting come in writing, and nothing starts before you have read them.
Before work starts
Baseline recorded
The numbers this work is meant to move, such as enquiries, quotations, orders, visits or renewals, written down so every later report has an honest comparison.
After the baseline
The first fix goes live
The fix we agreed to start with is put in place and measured against the baseline, whether that is a reply, a follow-up, a page, a listing or the handover between marketing and sales.
As agreed
Report against the baseline
What moved, what did not, and what changes next, in plain words. How often you get it is set in writing before work starts.
At renewal
Renew on the numbers
The term ends and you decide whether to continue from the results. The length is agreed in writing before anything starts.
How the work runs for PCB assembly companies
- 1
Go through the last quotes sent
Your estimator's old BOM replies show how long a quote took, what was missing from the files and which lots became orders.
- 2
Put a checklist between the zip file and the estimator
Gerbers, pick-and-place data, polarity marks and alternates are ticked off before pricing starts, and each file gets a named owner.
- 3
Describe the line the way a founder asks about it
Lot sizes you accept, parts you source, tests you run and the boards you build best, on pages an engineer can read quickly.
- 4
Choose which buyers to go after
Hardware startups find you through search; OEM sourcing heads need a pack; fabs and distributors can refer both.
- 5
Call after the first delivery
Yield, change requests and the next lot date the customer gives are written down per customer, so reorders are not left to memory.
