Electronics Procurement Checklist for Hardware Founders

A first production order is a different kind of purchase from a prototype order. It ties up cash, locks in design choices, assumes the product is compliant and sets a delivery date a customer will hold you to. At this stage a missing suffix on a part number, an unchecked lifecycle status or a loose "equivalent allowed" note can cost more than any price difference you negotiated.

The checklist below runs in the order the decisions should be made. Each section opens with the mistake it exists to prevent, because most startup sourcing failures are predictable: the same ten or so turn up again and again. Give every item an owner, a status and a link to the evidence. Mark an item "not applicable" only with a reason written next to it; a blank box is not an approval.

1. Pin down what you are building, and how many

The mistake: treating the prototype buy and the production buy as the same exercise. Ten boards bought on cut tape from a catalogue tell you little about reels, lead times or MOQ at volume.

• Product, model and hardware revision for this build are approved.
• Prototype, validation, pilot and saleable quantities are listed separately.
• The date parts are needed at the factory comes from the build plan, not the launch date.
• Yield loss, setup, test, rework and service spares are added to the quantity.
• Customer, safety, environmental and sector requirements are written down.
• One named person owns the purchase decision and the escalation path.

Split the sales forecast into firm, flexible and upside demand. Only the firm part should become a commitment you cannot unwind without the founder and whoever runs finance signing off. The forUdyog guide on prototype versus production manufacturing covers the wider shift between the two stages.

2. Make the BOM fit to quote

The mistake: sending suppliers a BOM line such as "10k resistor 0402". It leaves tolerance, power, voltage, temperature coefficient and manufacturer open, so every quote answers a different question and the comparison means nothing.

• Every line has its own internal part number.
• Manufacturer and full orderable MPN, including packaging suffix, are recorded.
• Description, value, package, tolerance and ratings agree with the MPN.
• Alternates are released by engineering; a distributor's suggestion is only a starting point.
• Datasheet, drawing and BOM revisions are controlled.
• Standard pack, moisture sensitivity level, date-code and CoC needs are stated.
• Do-not-substitute lines are flagged.

Search the BOM for duplicates and vague lines before it leaves the building. "USB-C connector" or "STM32 MCU" will not survive a production RFQ.

3. Check lifecycle and supply exposure

The mistake: assuming stock today means supply for the life of the product. A startup can complete certification just as a critical IC is moved to last-time-buy.

• Lifecycle status is checked on the manufacturer's own site and dated.
• NRND, last-time-buy and obsolete parts each have an approved action.
• Lead time is confirmed for the exact MPN and quantity.
• Single-source and long-lead lines are on a risk list with owners.
• Someone is subscribed to change and discontinuance notices for each critical part.
• The time needed to qualify an alternate is in the continuity plan.

Texas Instruments, for example, recommends that new designs consider an alternate for parts it marks NRND, last-time-buy or obsolete (checked October 2026). Other manufacturers use their own terms, so read each one's definitions instead of relying on a distributor's search filter.

4. Choose the buying channel

The mistake: buying from a source that looks genuine because the website is polished, a GST invoice is offered and the photo shows a sealed reel. None of that proves authorisation, chain of custody or how the parts were stored.

• Direct supply from the manufacturer has been considered.
• Manufacturer-authorised distributors for the exact line have been asked.
• Authorisation is confirmed on the manufacturer's website, not on a quote logo.
• Seller's legal entity, address, bank account and stock location agree.
• Stock ownership, original packaging and warranty position are known.
• Any non-authorised purchase goes through a separate, approved risk process.

ECIA's position is that the best guard against counterfeit parts is to buy from authorised distributors, and in June 2026 it published a position paper urging the industry to keep to authorised channels. TI states that it gives no warranty or support for semiconductors bought outside its authorised sources. If a shortage forces an independent buy, quarantine the lot, inspect and test it to a plan agreed in advance, and remember that testing cannot recreate missing paperwork. The guide to verifying authorised distributor status walks through the check.

5. Qualify the supplier and the exact offer

The mistake: approving a company on the strength of a good quote, without evidence about defects, delivery or the specific site that will supply you.

• Quality-system certificate scope covers the supplying site and activity.
• References or past delivery records have been reviewed.
• Inspection, non-conformance and corrective-action processes are understood.
• Capacity and the supplier's approach to allocation in a shortage are discussed.
• Lot traceability and document retrieval have been demonstrated, not described.
• Samples or a pilot lot are approved where the risk justifies it.

NIST's manufacturing extension programme suggests looking at total cost of ownership, quality systems and lot control, and supplier capacity before unit price. A supplier running very full or very empty is a warning sign in either direction.

6. Compare quotes on the cost of a usable part

The mistake: picking the lowest unit price. For an Indian buyer the catalogue price leaves out freight, insurance, customs duty, handling, currency and banking costs, finance, attrition and any MOQ balance that will never be used.

• Every supplier quoted the same BOM revision and quantity schedule.
• Currency, validity and price-change conditions are explicit.
• MOQ, order multiple and standard pack are shown separately.
• "In stock", lead-time start and promised ship date are distinguished.
• Freight, insurance, import and handling scope are included or priced.
• Payment, cancellation, reschedule and NCNR terms have been read.

Add goods, freight, insurance, duty, handling, any tax you cannot claim back, and finance cost to get landed cost. Then divide by the quantity you expect to use. Suppose a reel of 5,000 parts costs ₹40,000 landed but the forecast only needs 3,000 before the next revision: the usable cost is about ₹13.33 a part, not ₹8. The landed cost guide covers duty in detail. Use the ICEGATE duty calculator with your own reviewed classification; a rate copied from a similar-looking part is not reliable.

7. Get import and product compliance ready

The mistake: checking Indian compliance after the design is frozen. A certified module does not certify the finished product, and a missing registration can hold goods at the port.

• The importing entity holds a DGFT Importer-Exporter Code with current profile details.
• Eight-digit classification, description, origin and valuation are reviewed.
• Duty and notification assumptions are written down with the date checked.
• BIS registration applicability is checked for the product and its accessories.
• WPC Equipment Type Approval is checked for anything with a radio.
• Model, applicant, factory, test report and label on each registration all match.

The BIS Scheme II list and the WPC Wing's equipment type approval pages are the official references (checked October 2026). Both change, so recheck them before the first shipment and take specialist advice where classification is uncertain.

8. Write the requirements into the purchase order

The mistake: relying on "as per datasheet". It says nothing about mixed lots, opened moisture barrier bags, substituted parts or unannounced process changes.

• Exact MPN and a no-substitution clause.
• Original or agreed packaging, with ESD and moisture controls.
• Disclosure and segregation of mixed lots and date codes.
• CoC, country of origin and traceability documents to accompany the goods.
• Acceptance criteria, sampling plan and the route for deviations before shipment.
• Notice of product or process change and of discontinuance.
• The order acknowledgement is checked against the PO before shipment.

Where the supplier's standard terms conflict with your PO or the quote, settle it before goods ship and file the agreed version with the approval record.

9. Prepare receiving before the cartons arrive

The mistake: releasing material to the line because production is waiting, and losing track of which lot went where.

• Stores know the PO, package count and the identifiers to expect.
• A quarantine area and a quality owner are assigned.
• Labels, MPN, quantity, lot, date code and documents will be reconciled.
• Packaging, seals and moisture indicators will be inspected.
• Different lots will be kept apart.
• Each receipt gets an internal lot and package ID.

Record every split reel, line return and scrap. Link component package IDs to work orders and then to finished serial numbers. The guide to date codes, lot traceability and CoCs explains the records.

10. Close the loop after delivery

The mistake: measuring purchasing only on price variance, which rewards decisions that delay builds or leave excess.

• Received, accepted, rejected, issued and remaining quantities reconcile.
• Delivery is measured against the confirmed date and the build need date.
• Defects, document errors and response time go onto a supplier scorecard.
• Forecast and excess are reviewed before the next release.
• A traceability drill is run both ways: one lot forward to all affected units, one serial back to its lots.

The founder's one-page sign-off

Before a production PO goes out, the founder or a delegated approver should see one page.

A red item blocks the order. An amber item needs a named deviation, an owner and an expiry date.

Questions founders ask

When should NCNR terms be accepted?

Only when the design, the quantity and the demand behind it are understood and approved. Record the frozen window, any reschedule rights and who owns the stock if the forecast drops.

Can a spreadsheet run this checklist?

At modest scale, yes, if revisions, evidence links and ownership are controlled. Move to ERP or PLM when transaction volume or lot genealogy makes manual control unreliable.

Should the EMS partner buy everything?

It saves effort, but keep the approved manufacturer list, visibility of the buying channel and the excess-stock terms in your hands. For the critical lines, consider buying or nominating the source yourself.

If you want help organising the supplier side, describe the requirement on the RFQ page and post a QUICK RFQ. For the decisions that should be made even earlier, see planning component sourcing before product development.
