Detailed merch RFP: clause-by-clause prose guide

The long guide — what a buyer writes in each clause of the Request for Proposal, which numbers never get left out, which verbs replace which adjectives, and how everything ties to the Mexican compliance layer (CFDI 4.0, Carta Porte 3.0, NOM-050, USMCA, IMMEX) without the supplier picking up the phone.

Why a detailed RFP reads itself

A generic RFP produces generic proposals. When a buyer pastes a paragraph from a blog post and sends it to five suppliers in New York, Chicago, and Austin, all five responses sound like each other: every one promises “quality,” “fast turnaround,” and “competitive pricing,” and the final decision comes down to who replied first or who priced the cheapest, not who actually understood the program. A detailed RFP inverts that logic. Every clause carries numbers, units, and tolerances, so a serious supplier can quote without a single clarification call, and an informal supplier self-selects out.

Depth does not mean length. Depth means every assertion in the document is backed by a metric or a verifiable reference. “Combed cotton tee, 180 g/m², double-stitched seams, 1×1 rib collar, garment-dyed” is a clause. “Premium tee” is a hole in the prose that the supplier fills with whatever is on their shelf. Detailed prose closes the hole before the evaluation, not during it.

For Mexico-bound or USMCA-crossing programs, the prose has to be especially explicit on three planes. The first is fiscal: CFDI 4.0 with the comprobante type, the CFDI use code, the payment method, and — when the shipment crosses the border — the Carta Porte 3.0 complemento with the transit regime. The second is technical compliance: NOM-050-SCFI-2010 for textile labeling in Spanish, REACH SVHC and California Prop 65 when the destination crosses the border under USMCA, ISO 105-C06 or ASTM D5034 when the piece will see hard use. The third is operational: the prose has to distinguish between an IMMEX program where inputs are imported under a duty suspension and a regular program where VAT is credited against the domestic invoice. Each plane changes the supplier's response.

This guide walks the eight clauses a 12-to-18-page document usually carries: header, scope, technical brief, compliance, logistics, evaluation, timeline, and annexes. Each clause is broken into sub-clauses with the exact prose a US-based buyer can copy and adjust. The prose is not sold as final; it is sold as a first cut with verifiable numbers, enough to make the first round of proposals arrive comparable.

The assumed program for the examples is 2,500 units across five SKUs, delivery to three Mexican cities (CDMX, Monterrey, Guadalajara), a 45-business-day cycle from RFP issuance to PO signature, and a mixed fiscal regime (80% domestic market, 20% USMCA-bound export).

Clause by clause: the prose that closes the holes

  1. Clause 1 — Header and cover letter. Half a page with the program name, tracking number, issue date, proposal deadline (date and time, CDMX time zone), responsible buyer with their Mexican tax ID (RFC) if they have one, single Q&A contact (name, phone, email), and a three-line paragraph that says what is being competed, what is not, and why it is being competed now. The header does not sell. It frames.
  2. Clause 2 — Scope and volume. One page with audience (internal, channel, prospect, event), use case (onboarding, trade show, launch, year-end, key-account gifting), total units, number of SKUs with a one-line description of each, brands and sub-brands with their relative weight, cities with volume per city (CDMX 1,200, Monterrey 700, Guadalajara 600), and the budget band in MXN before VAT with an explicit range (“between MXN 680,000 and 820,000 plus VAT”). Scope is the clause that saves the most calls.
  3. Clause 3 — Technical brief per SKU. Three to five pages with one sheet per SKU: substrate with numbers (combed cotton 180 g/m², PU notebook 300 g/m², 18/8 stainless steel tumbler 500 ml), print method with color count and position (2-color screen print, front, 8 cm down from the collar), Pantone codes with thread and ink equivalents (Pantone 286 C — thread 28 224, ink CMYK 100/75/0/0), decoration area with tolerance (± 2 mm), individual packaging (recyclable polyethylene bag), and master pack (corrugated cardboard, 24 units, weight and dimensions). Three more pages if the piece ships in gift packaging or with instructions.
  4. Clause 4 — Compliance and certifications. One to two pages with the closed list: NOM-050-SCFI-2010 for textile labeling in Spanish, ISO 105-C06 for wash fastness (with the cycle count), California Prop 65 for California-bound shipments, REACH SVHC for European-bound shipments, IMMEX when it applies, and CFDI 4.0 with the comprobante type. Each compliance line carries its mandatory response question (“Attach a current certificate issued by an accredited laboratory”), not the standard by itself.
  5. Clause 5 — Logistics and delivery. One page with cities and addresses or delivery zones, delivery windows per city in business days, last-mile rule (DHL, FedEx, Estafeta, or local parcel depending on weight and urgency), master pack with weight and dimensions, gift packaging policy if any, and Carta Porte 3.0 issuance with the transit regime when the freight crosses the border or leaves an IMMEX warehouse. The prose also states who pays freight and under which invoice line it lives.
  6. Clause 6 — Evaluation criteria. Two pages with the five-criterion matrix (compliance 25%, technical capability 25%, proposal quality 15%, total price 25%, sustainability and risk 10%), a one-sentence description of each criterion, mandatory response format (PDF plus spreadsheet with five tabs), and the annex list the supplier must deliver. The prose in this clause is the difference between a clean comparison and a post-mortem fight.
  7. Clause 7 — Timeline and Q&A process. One page with 10 business days of Q&A, 15 for proposal, 5 for clarifications, 10 for decision and PO. The Q&A rule goes in writing: all questions in writing, all answers published to all bidders within 48 business hours, no one-to-one conversations. The rule protects the comparison and is citable in any later audit.
  8. Clause 8 — Annexes. Numbered list of annexes: technical brief per SKU, brand manual, blank scorecard, response template (spreadsheet), compliance glossary, detailed timeline, coverage map per city, and draft contract. Each annex has its own version control table with date.

Prose anti-patterns that break the comparison

The first anti-pattern is the ambiguous verb. “Several,” “a few,” “various,” “standard.” These words look like they fill space and leave the supplier guessing. Detailed prose replaces each with a number, its unit, and its window.

The second anti-pattern is the adjective without a metric. “Premium,” “high quality,” “durable,” “resistant.” A serious buyer pastes the number the adjective was hiding: “combed cotton 180 g/m²,” “tensile strength 80 N minimum per ASTM D5034.” Without the metric, the supplier prices in for the risk.

The third anti-pattern is half-stated compliance. “Comply with applicable regulation” without enumerating the standards lets the supplier pick the minimum. Detailed prose lists every standard by name and number, and asks for specific evidence (certificate, lab report, declaration).

The fourth anti-pattern is mixed currencies without an exchange rate. When part of the program is invoiced in USD and part in MXN, the prose defines at which rate the comparison is made (DOF rate from the business day before the deadline), how each part is invoiced (CFDI in MXN, invoice in USD), and under which fiscal regime each line sits.

The fifth anti-pattern is a deadline without days. “Standard turnaround” or “usual timelines” are disguised agreements. Detailed prose states the number: “five to eight business days from strike-off approval, with a 35% surcharge for delivery in three to five business days.”

The sixth anti-pattern is the brand mark without the asset. Asking for the logo “in full color” without sending the editable SVG and the brand manual with Pantone and safe area opens the door to a supplier quoting against a badly cropped JPG. Detailed prose enumerates the files delivered and asks the supplier to quote against that material.

The seventh anti-pattern is freight and VAT outside the comparison line. If the RFP asks for unit price without VAT and without freight, the evaluation sums them later and surprises appear. Detailed prose asks for the three lines — unit price before VAT, freight per city, VAT at 16% — and the matrix compares the landed total.

The eighth anti-pattern is sustainability in one sentence. “Program committed to the environment” is not a clause. Detailed prose enumerates the required attributes (GOTS-certified organic cotton, water-based ink, recyclable packaging, FSC for the master carton), the certifications the supplier must present, and the percentage weight sustainability carries in the scorecard.
