Start from your day, not the feature list
Feature lists all look the same. What separates systems is how they handle your ordinary day: a rep without signal, a customer over their limit, a short-dated lot, a month that will not balance. Write down your ten most common transactions and your five worst recent problems before you see a single demo.
Then ask every vendor the same questions, in the same order, and have them show each answer on screen with your data rather than describe it. The twelve questions below are a starting point; add your own.
TipSend the questions to vendors before the demo, so the time is spent showing answers rather than giving the standard tour.
Questions 1 to 3: the field
For a distributor, the van and the rep’s phone are where most errors start. These questions test whether the field and the office run on one set of rules.
- Can a rep sell, invoice and collect with no signal, and what happens to those documents when the signal returns? Ask to see it with the phone in flight mode.
- Is each van its own stock location, and is the day closed with a count of stock and cash that the office approves?
- Are credit limits, discount ceilings and the rep’s catalogue enforced by the server, so the rep app cannot get round them?
Questions 4 to 6: stock
Stock is where distributors lose money quietly. These questions show whether the system tracks stock the way your warehouse actually holds it.
- Does it track lots and expiry dates, and pick soonest expiry first by default when no lot is named?
- Can each item be bought, stored, sold and counted in different units, such as cartons and pieces, with the conversion kept per item?
- Can you count one bin at a time while the warehouse keeps working, with an approval before the difference posts?
Questions 7 to 9: money
An ERP earns its name when operations and the books are one record. If anyone has to re-key the day into accounting, you have two systems, not one.
- Does every invoice, payment and stock movement post its own journal, and can you click from a journal to the document behind it and back?
- Once a month is closed, is it closed against every channel, including the till and the vans, and can it be locked for good?
- Is e-invoicing built and in use for your country, from every channel you invoice through, including invoices made offline?
Questions 10 to 12: the company and control
These questions decide whether the system fits the company you will be in three years, not only the one you are today.
- Can you run several companies under one account, each with its own currency, fiscal year and document numbers, and report on them together?
- Who can do what? Ask how roles are set, whether the server refuses what a screen hides, and what the audit trail records.
- What does the system not do today? Ask for the list in writing, and ask how your data gets in and out: imports, exports and links to other systems.
Test the answers and count the full cost
A yes in a meeting is not an answer. Ask for a test account with your own items, customers and prices, and run a week of real transactions through it, including the awkward ones: a return, a credit hold, a short count, a closed month.
Then compare the cost of the first year, not the monthly price. Licences are often the smaller part; setup, data migration, training and printers add up.
Finally, speak to two customers of each vendor who run a business like yours, and ask what took longer than promised.
TipAsk each vendor to price the same scope in writing, so you compare like with like.
