OEM and manufacturer authorisation letters in tenders.
Original Equipment Manufacturer (OEM) and manufacturer authorisation letters appear frequently in technical and product procurement. They can be used to prove that a bidder is authorised to sell, support, distribute, install or otherwise represent a manufacturer's products.
The dangerous assumption is that any generic “authorised reseller” letter will satisfy any tender. It may not.
First determine what the tender actually requires
Read the requirement literally. The bid may require:
- An authorised reseller or distributor letter
- A manufacturer authorisation form in a prescribed format
- Confirmation that the bidder may supply a specific product range
- Confirmation of local warranty or technical support
- Confirmation that the offered product is genuine and supported
- An OEM relationship for the duration of the contract
- A letter addressed to the procuring institution or referencing the tender number
These are not interchangeable requirements.
What a useful authorisation letter should identify
Where the tender does not prescribe its own form, the strongest letter normally makes the relationship easy to verify. It should clearly identify the manufacturer, the bidder, the relevant product or product family, the nature of the authorisation and the person issuing it.
If the tender requires project-specific authorisation, include the tender or project reference and ensure the letter is current for the submission period.
Match the legal names exactly
Check the bidder's legal name against the letter. A manufacturer letter issued to a related business, previous trading name or individual does not automatically prove authorisation for the bidding entity.
Check the scope of the relationship
“Reseller”, “distributor”, “service partner”, “integrator” and “authorised agent” can mean different things. If the tender requires installation or warranty capability, a letter proving only resale rights may not be enough.
Connect the letter to the offered product
Use a technical schedule that identifies manufacturer, model number and supporting evidence. The OEM letter should support the same manufacturer and product relationship described in that schedule.
If the tender permits an alternative product, first perform the equivalence assessment described in our guide to “or equivalent” specifications.
Do not fabricate urgency around an OEM
Manufacturer authorisations often take time because they require internal approval. Request them early, provide the exact tender number and closing date, and send the relevant wording from the tender so the manufacturer understands what must be confirmed.
Keep verification details
Where possible, the letter should contain verifiable issuer details and be on recognisable manufacturer letterhead. Keep the source email and contact information in the bid working papers in case clarification is requested.
Watch expiry and territory
Some authorisations are restricted by date, product, geography or customer type. Confirm that the letter covers South Africa and remains valid for the relevant period.
Examples from public procurement practice
South African public tender documents can expressly score or require OEM confirmation. Recent eTender documents have required bidders to provide valid OEM authorisation confirming approved distributor or agent status, while others require an MOU or authorisation letter where the bidder is not the manufacturer. The lesson is not that every tender needs one; it is that the tender-specific wording matters.
File the letter as evidence, not decoration
In the bid pack, place the letter where the evaluator expects it and reference it from the relevant returnable or technical matrix. A strong evidence pack should make the relationship obvious without forcing the evaluator to search through hundreds of pages.
