Step 1: Define the problems and expected outcomes. Write down what's actually wrong and convert each problem into a measurable goal. "We need a modern ERP" gives a project nothing to aim at; "reduce expiry write-offs by a third within a year" gives it a target, a deadline, and a way to know whether the investment worked.
Step 2: Document the key processes. Map purchasing, receiving, batch records, ordering, pricing, picking, delivery, returns, recalls, and invoicing—capturing for each who participates, what data moves, and where the manual work hides. This document becomes the yardstick every vendor gets measured against.
Step 3: Prioritize requirements. Sort into mandatory (the company can't operate without it: batch and expiry support, FEFO, customer-specific pricing, multiple units of measure, accounting integration, batch-to-customer lookup), important (real value, livable workaround), and additional (never a reason to choose one system over another). A list where everything is equally critical prevents objective comparison—and hands the decision to whichever vendor demos best.
Step 4: Establish the scale and complexity of the business. Gather the baseline a vendor will ask about—SKUs, orders per day, customers, warehouses, users, entities, currencies, channels, vehicles, integrations—and resist judging size by headcount or turnover. A twelve-person distributor with short-shelf-life batches, catch weight, and its own trucks is operationally complex whatever its revenue says, and complexity drives solution type, cost, and timescale.
Step 5: Choose the appropriate solution type. Decide the level before comparing brands, using the taxonomy above: basic record-keeping for simple single-warehouse operations; specialist distributor software for industry scenarios without a full ERP program; food distribution ERP when systems have fragmented; an enterprise ecosystem for multi-entity groups; a standalone WMS, routing tool, or B2B platform when the ERP generally works and one process needs serious improvement.
Step 6: Check industry-specific functions. Put the same questions to every vendor—batches and expiry dates, automatic FEFO, catch weight, units of measure, batch-to-customer lookup, batch blocking, returns and recalls, customer-specific pricing, multi-warehouse support—and weight the scoring by your model: catch weight is existential for a protein distributor and noise for a beverage one.
Step 7: Assess integrations and hardware compatibility. List every system and device the newcomer must talk to, from accounting and EDI to scales, scanners, and temperature sensors—establishing for each what data moves, which system is the source of truth, and what happens on failure. A logo on a vendor's integrations page is not an integration.
Step 8: Choose the deployment model. Apply the cloud/on-premises/hybrid comparison from the previous section to your own constraints—a generic recommendation would be worth what it cost you.
Step 9: Assess usability for every role. The daily users are salespeople, buyers, warehouse staff, drivers, and finance—a much wider cast than the managers watching the demo. Count the actions behind a standard order, receipt, and pick, and put real future users in the demonstrations. Their verdict decides everything: if pickers hate the system, it fails regardless of its feature list.
Step 10: Check scalability. Can it absorb more of everything—orders, SKUs, warehouses, entities, channels, users? Ask for reference customers at your scale or larger, get specific about what growth costs, and test the deeper definition: real scalability means more complex processes handled without a spreading web of manual workarounds.
Step 11: Assess security and reliability. Ask how access rights restrict by role, whether there's an activity log, how backups run and how often recovery is tested, and how data is stored, exported at contract end, and deleted afterward. Check availability commitments separately.
Step 12: Assess the vendor and quality of support. You're choosing a partner as much as a product: food-distribution experience, customers like you, implementation record, roadmap, and financial stability—with support terms pinned down in writing, including who supports integrations after the implementation team moves on. Read food service distribution software ratings like a researcher: a wall of five-star reviews from businesses nothing like yours says little about your fit.
Step 13: Request a demonstration using real scenarios. Write one script and give it to every vendor unchanged—receive a batch with expiry date, order at individual pricing, pick by FEFO, handle catch weight, ship partially, substitute, process a return, and trace a batch to every customer who received it—then push into the ugly cases: insufficient stock, expired product, an order changed mid-pick, a failed integration. A rehearsed interface tour is a performance; identical scripts against your real scenarios are evidence.
Step 14: Off-the-shelf solution or bespoke development? In most cases, start with a ready-made industry product or configurable platform and adapt it—off-the-shelf implements faster, while ground-up development costs more, takes longer, and leaves you maintaining everything forever. There's also a middle path, and for many distributors it's the strongest of the three: keep a ready-made ERP for standard internal operations, connect a flexible B2B commerce platform for the customer scenarios that differentiate you, and join the pieces through APIs—bespoke-grade fit at the customer edge without bespoke fragility underneath, provided the platform layer comes with guaranteed upgrades rather than a codebase that fossilizes the day the contractors leave.
