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.

Realistic editorial illustration of electrical equipment manufacturers at work in India

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.

  1. 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.

  2. 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.

  3. Turnkey and consigned explained

    A simple page that explains the two ways of working, who buys what, and how shortages are handled.

  4. Quote tracker

    Every BOM logged with the buyer, the lot size, the price and a follow-up date.

  5. First lot to second lot routine

    A plan to contact each customer after delivery, collect feedback on yield, and learn the next lot date.

  6. Customer audit pack

    Process records, calibration and training records in one maintained folder.

  7. 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.

Worth a page and a campaign of their own

Prototype and pilot lots for hardware startups · Turnkey assembly with component sourcing · Industrial controller and power electronics boards · IoT and smart meter assembly · Automotive and EV board assembly · Functional testing and programming · Box build with enclosures and wiring · Long-run production for repeat customers

Priority campaigns

Campaigns for what PCB assembly companies most want to sell.

Each one planned around when your buyers decide, and measured against the baseline.

  • Hardware startup campaign

    Search advertising and content for founders needing a first batch built, with a landing page that explains the process step by step.

  • OEM sourcing outreach

    A capability pack, a reference board photo set and direct outreach to purchase heads at electronics makers.

  • EV and automotive electronics campaign

    Content on testing, traceability and board handling aimed at EV component makers and their sourcing teams.

  • Medical and industrial electronics campaign

    A page on low-volume, high-mix assembly and documentation, with outreach to makers of instruments and controllers.

  • Repeat-lot reminder campaign

    A call and message script for customers whose boards repeat, built around the last lot size and any change requests.

Beyond search

Where we reach buyers of PCB assembly companies, beyond Google.

Search matters, but it is rarely the only way this industry's buyers find a supplier.

  • Hardware startups and incubators

    Content and an enquiry path for founders who need a first build, with a presence in the incubators near your plant.

  • OEM design and sourcing teams

    A purchase team adding an assembler wants a vendor pack and quality papers; a record shows which OEM has reached which stage.

  • PCB fabs and component distributors

    Referral conversations with the fabs and distributors your customers already buy from.

  • Automotive, EV and industrial brands

    Sector pages and sample references for buyers in segments with strict quality needs.

  • Existing customers

    Customers whose boards repeat are called with the last lot and their change requests in front of you, not a cold script.

Who it is for

This is written for these PCB assembly companies.

  • Prototype and low-volume SMT assembly shops for startups
  • Turnkey assemblers who source components for OEMs
  • Consigned-parts assembly for brands that buy their own components
  • High-mix, low-volume lines for industrial and medical electronics
  • Automotive and EV electronics assemblers
  • Box-build and final assembly providers with enclosure and harness work
  • Contract manufacturers for consumer and IoT products
  • Rework and repair houses for expensive boards

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.

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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. 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. 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. 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. 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. 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.

FAQ

Questions PCB assembly companies ask before they call.

Not here? More answers, or ask on WhatsApp.

How do we attract OEMs and not only one-off prototype buyers?
Describe the line and the quality steps in language a purchase team trusts, and name the segments you build for. Then send sourcing heads a capability pack directly. Prototype buyers are reached through search.
Should we advertise turnkey or consigned assembly?
Both, with a clear explanation of each. A founder who does not know the difference asks the same questions on every call, so a plain page on it answers them first.
How do we stop losing the second lot?
Call after the first delivery and ask how the boards performed. We set up a record for each customer, with a short note of the next lot date the customer gave, so the follow-up is not left to memory.
Can you help with customer audits and approvals?
We organise the documents and the vendor pack, but the approval belongs to the customer. Your quality head decides what goes in the pack and signs it.
Does IndiaMART work for assembly services?
It brings a volume of enquiries, and some arrive without a BOM. We set up a sort so complete BOM requests reach your estimator first.
How much does it cost?
There is no price list, because the work differs by business. The fee is scoped after we have read your brief and spoken to you, and put in writing before anything starts, split into our time, your media spend and production.
How long is the contract?
The term is agreed in writing after we have spoken, along with the fee and the reporting. It is never a default twelve months, and renewal is decided on the numbers against the baseline recorded at the start.
How soon will we see results?
Fixes to reply time, follow-up and your Google Business Profile are the quickest to show, because the enquiries already exist. Ads can follow soon after follow-up is in place. SEO and content take longer. How long each takes depends on your business, and we tell you which applies to you after we have spoken. Nothing here is guaranteed.
Who will actually do the work?
The person you speak to before anything starts. We work from one office in Nagarbhavi, Bengaluru, with no account managers in between.
What do you need from us?
To start, last month's enquiries in any format and time with whoever handles them. After that, access to the accounts the work touches, such as the website, Google Business Profile or CRM.
