Write the operation on one page
Record what you sell or consume, where it is stored, who touches it, and where orders originate. Include current and reasonably expected order counts, locations, users and connected systems. Separate observed numbers from estimates; a hopeful growth target should not masquerade as today's requirement.
Describe your inventory boundary. Does it include customer-owned goods, demonstration units, parts in vehicles or stock at a contractor? These questions matter even when the total quantity is small. Add the name of the person accountable for each boundary. “Everyone updates inventory” is not an ownership rule.
Convert wishes into demonstrations
Replace “good barcode support” with “a receiver scans a supplier label, sees the correct item, records a partial delivery and can explain the balance afterward.” Replace “multi-location” with “goods leave Warehouse A, remain identifiable during transfer and are received at Warehouse B without being available twice.”
Use four columns: decision, example transaction, acceptable result and evidence. The evidence might be a visible movement history, a permission test or an export that reconciles. Label requirements as mandatory, useful or deferred. A mandatory requirement needs a real consequence if absent; visual preference alone rarely deserves that label.
Specify exceptions before integrations
A connection logo says little about ownership. For every sales channel, choose the system that creates products, changes available stock and records fulfillment. Then ask what happens to cancellations, edited orders, refunds, bundles and duplicate messages. Do not describe an integration as complete until those cases have a supported path.
Zoho's item-preferences documentation illustrates another choice: serial and batch information can be collected against different transaction types. The useful requirement is not merely “batch tracking”; it is which staff must capture it and at what moment. Your own traceability needs should drive that decision.
A fictional brief that a vendor can answer
Consider a wholesale hardware team with four users, two buildings and a web store. Its first three requirements might be: reserve an accepted trade order; receive 18 of 24 ordered boxes; and move stock between buildings with an accountable handoff. Add the box-to-each conversion and an incorrectly labelled delivery as exceptions. All quantities here are illustrative.
If this business only distributes finished goods, production scheduling should not dominate its shortlist. Conversely, a maker consuming ingredients must include the transformation from components to finished units. inFlow's separate product families make that distinction explicit, but other vendors should receive the same brief. Finish with a signed list of mandatory tests, an accountable evaluator and a budget range that includes implementation. That becomes the script for your demo, rather than a list the salesperson can satisfy with checkmarks.
