What to Include in an Ecommerce Fulfillment RFP

A fulfillment RFP is not a price-collection exercise. The goal is to find an operational partner who will own a critical piece of your customer experience: the moment an order leaves a warehouse and arrives at a doorstep. Because 3PLs vary widely in network footprint, technology stack, SLA commitments, and pricing structure, a generic procurement document will not expose the tradeoffs that matter. You need a document built around the specific operational realities of ecommerce fulfillment.

A request for proposal gives you two concrete benefits. First, it forces internal alignment: every stakeholder must agree on requirements before a single vendor sees the document. Second, it creates a structured basis for comparison. When providers answer identical questions, you can evaluate them on the same criteria rather than reconciling proposals written in incompatible formats. An RFP also signals to vendors that you are a serious, prepared buyer, which typically produces more accurate and complete responses.

The first section of any fulfillment RFP must describe your business in enough detail for a 3PL to price accurately and confirm fit. Include your current and projected monthly order volume, your SKU count and whether it is growing, your average units per order, your product types (fragile, temperature-sensitive, regulated, hazmat, or standard parcel), and the channels you sell on (DTC website, marketplace, wholesale, or social commerce). Without this data, a 3PL cannot tell you whether their facility configuration, labor model, or carrier relationships are compatible with your needs.

Peak season capacity is one of the most common failure modes in 3PL relationships. Ask providers to confirm they can handle multiples of your normal volume during high-demand periods such as a product launch or a holiday surge. Require them to provide specific peak-season data: actual order volumes processed, same-day fulfillment rates achieved, and how accuracy held up under load. Also specify whether you require B2B fulfillment in addition to DTC, since B2B orders carry different requirements including pallet-level shipments, retailer compliance labels, EDI connectivity, and specific routing guides.

If your catalog includes products with expiration dates or lot numbers, state that requirement explicitly and ask whether the provider's warehouse management system supports lot tracking and first-expired-first-out (FEFO) logic. A 3PL optimized for apparel replenishment may have no capability for expiry management, and discovering that after onboarding is costly.

SLAs are the contractual core of a 3PL relationship. Your RFP must require providers to state their committed performance targets for the three most important fulfillment metrics: on-time shipping (the percentage of orders that ship on the day they are due to ship), order accuracy (the percentage of orders sent to customers without errors such as wrong item or wrong quantity), and inventory accuracy (the degree to which recorded inventory matches physical inventory in the facility). Order accuracy errors compound quickly because they distort your inventory count and create downstream stockout risk.

Ask each provider to state their daily order cutoff time for same-day shipment and whether that cutoff is fixed or varies by carrier pickup schedule. Some 3PLs set cutoffs based on carrier pickup times, while others that operate their own transportation can receive orders outside standard windows. Require providers to explain what corrective action or financial remedy they offer when they miss a committed SLA. A target that carries no consequence when missed is not a real SLA. Also ask about how the provider tracks and reports on these metrics: does a live dashboard exist, or do you only see performance in a monthly PDF report?

For returns, require a separate SLA section. Ecommerce return rates reached an estimated 19.3 percent of online sales in 2025. A return that sits unprocessed in a warehouse ties up inventory, distorts stock counts, and increases the likelihood that the customer does not come back. Ask for committed turnaround times for intake, inspection, restocking of sellable units, and disposition of unsellable inventory. Ask whether the provider has dedicated reverse logistics infrastructure or treats returns as a secondary workflow bolted onto outbound operations.

Fulfillment pricing is notoriously opaque. A low headline pick-and-pack rate can be overshadowed by receiving fees, monthly storage charges, account setup fees, minimum monthly spend requirements, and peak-season surcharges. Your RFP must require an itemized breakdown of every fee category. At minimum, request line items for: receiving fees (flat rate or hourly per inbound shipment), storage fees (per cubic foot, per bin, per pallet, or per SKU), pick-and-pack fees (per unit or per order), outbound shipping costs, account setup fees, return processing fees, and any applicable minimum monthly spend. If the provider charges peak-season surcharges, require the timing, trigger thresholds, and rates to be stated in the proposal.

Storage pricing models differ in ways that significantly affect cost depending on your catalog. Some 3PLs charge by cubic foot of space occupied, which favors dense, small-SKU catalogs. Others charge by pallet or bin, which can be more economical for slow-moving bulky goods but expensive for large SKU counts with low velocity per SKU. Ask which model applies and request a sample calculation using your own SKU mix and volume figures so comparisons are apples-to-apples.

Also ask whether the provider allows you to use your own negotiated carrier rates or whether all shipping must go through their carrier accounts. If you have volume-based rates with a specific carrier, being forced onto the 3PL's carrier contract may cost more than the fulfillment savings. If the provider handles international freight, ask whether customs brokerage fees and import duties are included in quoted rates or billed separately.

A 3PL's warehouse management system (WMS) is the operational backbone for inventory tracking, order processing, and reporting. Your RFP must ask each provider which WMS they operate, how orders are pushed from your ecommerce platform to their WMS, and what the typical timeline to go live is. If you run custom order routing logic, inventory allocation rules, or channel prioritization, ask whether the 3PL has a documented API and request a copy of that documentation before you commit. A 3PL that cannot provide API documentation is unlikely to support the integrations your operation requires at scale.

Integration failure is a real onboarding risk. Connecting a WMS with an order management system and an ERP can take significant time and resources, and rebuilding those integrations when you switch providers later is expensive and disruptive. Your RFP should therefore require providers to list the integrations they natively support, whether there are additional fees for custom integrations, and which ecommerce platforms, order management systems, and marketplace channels they have verified connections with.

For reporting, require providers to describe the reporting tools and dashboards available to you as an operator. Ask whether the dashboard covers order accuracy rate, fulfillment speed by day, shipping performance by carrier and zone, and cost per order. Understand whether data is refreshed in real time or on a delay. If your RFP requires inventory accuracy reporting, ask how the provider handles cycle counts and rolling audits to detect and correct discrepancies between system records and physical stock.

Where a 3PL's facilities are located relative to your customer base directly determines the delivery speeds and shipping costs you can achieve. A single warehouse in one region forces long-zone shipments to customers on the opposite coast, raising both cost and transit time. Your RFP must ask each provider to identify which specific facilities would handle your volume, where those facilities are located, and what average delivery speed you can expect to the zip codes or regions where most of your customers are concentrated.

Distributed inventory across multiple fulfillment nodes can reduce shipping zones and lower per-shipment cost, but it also adds complexity to inventory allocation and replenishment. If a provider offers distributed inventory, ask whether that capability is included in their standard pricing or requires a separate arrangement. Also ask how inventory is rebalanced across nodes when one location runs low and another runs high, and what the lead time is for that process.

If you sell internationally or plan to, ask how many countries the provider services, whether they have fulfillment infrastructure in those markets or rely on cross-border shipping from domestic facilities, and how they handle customs documentation and duties. A 3PL with a physical presence in the markets that matter to your business allows you to hold inventory closer to customers, shortening delivery times and reducing shipping costs compared to fulfilling everything from a single domestic origin.

Before you send the RFP, your team must agree on how you will score the responses. Defining evaluation criteria in advance prevents the selection process from drifting toward the vendor that presents best rather than the vendor that fits best. Common scoring dimensions for a fulfillment RFP include: operational capability and SLA commitments, technology and integration depth, pricing and total cost of ownership, geographic network fit, returns and reverse logistics capability, and references from clients with a similar order profile to yours.

Weight each dimension according to your business priorities before any proposals arrive. A brand competing on two-day delivery should weight network geography and on-time SLAs heavily. A brand with a high return rate should weight reverse logistics capability accordingly. Once proposals are received, use the same scorecard for every provider so that evaluation is structured and defensible. Require each evaluator on your team to score independently before the group compares results, which reduces anchoring bias from whoever speaks first.

After scoring, shortlist two or three providers and request site visits or live operational demonstrations using your actual order scenarios. References from brands with similar volume, SKU complexity, and channel mix are more informative than generic client lists. Ask references specifically whether the provider met SLA commitments during peak periods, how responsive their account team was when issues arose, and whether the billing matched the original proposal. Those three questions will surface more decision-relevant information than any other reference check.
